dryers. DOE has determined that the amended energy conservation standards for these
products would result in significant conservation of energy and are technologically
feasible and economically justified.
DATES: The effective date of this rule is [INSERT DATE 120 DAYS AFTER DATE
OF PUBLICATION IN THE FEDERAL REGISTER]. If adverse comments are
received by [INSERT DATE 110 DAYS AFTER DATE OF PUBLICATION IN
2
THE FEDERAL REGISTER] and DOE determines that such comments may provide a
reasonable basis for withdrawal of the direct final rule under 42 U.S.C. 6295(o), a timely
withdrawal of this rule will be published in the Federal Register. If no such adverse
comments are received, compliance with the amended standards established for consumer
clothes dryers in this direct final rule is required on and after March 1, 2028. Comments
regarding the likely competitive impact of the standards contained in this direct final rule
should be sent to the Department of Justice contact listed in the ADDRESSES section on

Synopsis of the Direct Final Rule
The Energy Policy and Conservation Act, Public Law 94-163, as amended
(“EPCA”),
1
authorizes DOE to regulate the energy efficiency of a number of consumer
1
All references to EPCA in this document refer to the statute as amended through the Energy Act of 2020,
Pub. L. 116-260 (Dec. 27, 2020), which reflect the last statutory amendments that impact Parts A and A-1
of EPCA.
7
products and certain industrial equipment. (42 U.S.C. 6291–6317) Title III, Part B of
EPCA
2
established the Energy Conservation Program for Consumer Products Other Than
Automobiles. (42 U.S.C. 62916309) These products include consumer clothes dryers,
the subject of this direct final rule. (42 U.S.C. 6292(a)(7))
Pursuant to EPCA, any new or amended energy conservation standard must,
among other things, be designed to achieve the maximum improvement in energy
efficiency that DOE determines is technologically feasible and economically justified.
(42 U.S.C. 6295(o)(2)(A)) Furthermore, the new or amended standard must result in
significant conservation of energy. (42 U.S.C. 6295(o)(3)(B))
In light of the above and under the authority provided by 42 U.S.C. 6295(p)(4),
DOE is issuing this direct final rule amending energy conservation standards for
consumer clothes dryers.
The adopted standard levels in this direct final rule were proposed in a letter
submitted to DOE jointly by groups representing manufacturers, energy and
environmental advocates, consumer groups, and a utility. This letter, titled “Energy
Efficiency Agreement of 2023” (hereafter, the “Joint Agreement”
3
), recommends specific
energy conservation standards for consumer clothes dryers that, in the commenters view,
would satisfy the EPCA requirements in 42 U.S.C. 6295(o). DOE subsequently received
letters of support from States—including New York, California, and Massachusetts

and utilities—including San Diego Gas and Electric (“SDG&E”) and Southern California
Edison (“SCE”)
5
—advocating for the adoption of the recommended standards.
In accordance with the direct final rule provisions at 42 U.S.C. 6295(p)(4), DOE
has determined that the recommendations contained in the Joint Agreement are compliant
with 42 U.S.C. 6295(o). As required by 42 U.S.C. 6295(p)(4)(A)(i), DOE is also
simultaneously publishing elsewhere in this Federal Register a notice of proposed
rulemaking (“NOPR”) that contains standards identical to those adopted in this direct
final rule. Consistent with the statute, DOE is providing a 110-day public comment
period on the direct final rule. (42 U.S.C. 6295(p)(4)(B)) If DOE determines that any
comments received provide a reasonable basis for withdrawal of the direct final rule
under 42 U.S.C. 6295(o) or any other applicable law, DOE will publish the reasons for
withdrawal and continue the rulemaking under the NOPR. (42 U.S.C. 6295(p)(4)(C)) See
section II.A of this document for more details on DOE’s statutory authority.
The amended standards that DOE is adopting in this direct final rule are the
efficiency levels recommended in the Joint Agreement (shown in Table I.1). The
standards are expressed in terms of the combined energy factor (“CEF
D2
”), measured in
pounds per kilowatt-hour (“lb/kWh”), as determined in accordance with DOE’s consumer
clothes dryer test procedure at title 10 of the Code of Federal Regulations (“CFR”) part
430, subpart B, appendix D2 (“appendix D2”). The CEF metric includes active mode,
standby mode, and off mode energy use. The amended standards recommended in the

Joint Agreement are represented as trial standard level (“TSL”) 3 (hereinafter the
“Recommended TSL”) and are described in section V.A of this document. The Joint
Agreement’s standards for consumer clothes dryers apply to all products listed in Table
I.1 and manufactured in, or imported into, the United States starting on March 1, 2028.

A. Benefits and Costs to Consumers
Table I.2 summarizes DOE’s evaluation of the economic impacts of the adopted
standards on consumers of consumer clothes dryers, as measured by the average life-
cycle cost (“LCC”) savings and the simple payback period (“PBP”).
6
The average LCC
savings are positive for all product classes, and the PBP is less than the average lifetime
of consumer clothes dryers, which is estimated to be 14 years (see section IV.F of this
document).
6
The average LCC savings refer to consumers that are affected by a standard and are measured relative to
the efficiency distribution in the no-new-standards case, which depicts the market in the compliance year in
the absence of new or amended standards (see section IV.F.9 of this document). The simple PBP, which is
designed to compare specific efficiency levels, is measured relative to the baseline product (see section
IV.C of this document).

DOE’s analysis of the impacts of the adopted standards on consumers is described
in section IV.F of this document.
B. Impact on Manufacturers
The industry net present value (“INPV”) is the sum of the discounted cash flows
to the industry from the base year (2024) through the end of the analysis period, which is
30 years from the analyzed compliance date.
7
Using a real discount rate of 7.5 percent,
DOE estimates that the INPV for manufacturers of consumer clothes dryers in the case
without amended standards is $2.12 billion in 2022$.
8
Under the adopted standards,
which align with the Recommended TSL for consumer clothes dryers, DOE estimates the
change in INPV to range from -6.8 percent to -5.7 percent, which is a decrease of
7
DOE’s analysis period extends 30 years from the compliance year. The analysis period for the MIA
ranges from 20242056 for the no-new-standards case and all TSLs, except for TSL 3 (the Recommended
TSL). The analysis period for the Recommended TSL ranges from 20242057 due to the 2028 compliance
year.
8
The no-new-standards case INPV of $2.12 billion reflects the sum of discounted free cash flows from
20242056 (from the reference year to 30 years after the 2027 compliance date) plus a discounted terminal
value.
11
approximately $144.2 million to a decrease of approximately $119.7 million. In order to
bring products into compliance with amended standards, it is estimated that industry will
incur total conversion costs of $180.7 million.
DOE’s analysis of the impacts of the adopted standards on manufacturers is
described in section IV.J and section V.B.2 of this document.
C. National Benefits and Costs
9
DOE’s analyses indicate that the adopted energy conservation standards for
consumer clothes dryers would save a significant amount of energy. Relative to the case
without amended standards, the lifetime energy savings for consumer clothes dryers
purchased in the 30-year period that begins in the anticipated year of compliance with the
amended standards (2028–2057), amount to 2.7 quadrillion British thermal units (“Btu”),
or quads.
10
This represents a savings of 11 percent relative to the energy use of these
products in the case without amended standards (referred to as the “no-new-standards
case”).
The cumulative net present value (“NPV”) of total consumer benefits of the
standards for consumer clothes dryers ranges from $ 9.23 billion (at a 7-percent discount
rate) to $20.08 billion (at a 3-percent discount rate). This NPV expresses the estimated
9
All monetary values in this document are expressed in 2022 dollars and, where appropriate, are
discounted to 2024 unless explicitly stated otherwise.
10
The quantity refers to full-fuel-cycle (“FFC”) energy savings. FFC energy savings includes the energy
consumed in extracting, processing, and transporting primary fuels (i.e., coal, natural gas, petroleum fuels),
and, thus, presents a more complete picture of the impacts of energy efficiency standards. For more
information on the FFC metric, see section IV.H.2 of this document.
12
total value of future operating-cost savings minus the estimated increased product and
installation costs for consumer clothes dryers purchased during the period 20282057.
In addition, the adopted standards for consumer clothes dryers are projected to
yield significant environmental benefits. DOE estimates that the standards will result in
cumulative emission reductions (over the same period as for energy savings) of 57.1
million metric tons (“Mt”)
11
of carbon dioxide (“CO
2
”), 13.9 thousand tons of sulfur
dioxide (“SO
2
”), 116.5 thousand tons of nitrogen oxides (“NO
X
”), 527.6 thousand tons of
methane (“CH
4
”), 0.5 thousand tons of nitrous oxide (“N
2
O”), and 0.1 tons of mercury
(“Hg”).
12
The estimated cumulative reduction in CO
2
emissions through 2030 amounts
to 1.3 Mt, which is equivalent to the emissions resulting from the annual electricity use of
more than 260 thousand homes.
DOE estimates the value of climate benefits from a reduction in greenhouse gases
(“GHG”) using four different estimates of the social cost of CO
2
(“SC-CO
2
”), the social
cost of methane (“SC-CH
4
”), and the social cost of nitrous oxide (“SC-N
2
O”). Together
these represent the social cost of GHG (“SC-GHG”). DOE used interim SC-GHG values
(in terms of benefit per ton of GHG avoided) developed by an Interagency Working
Group on the Social Cost of Greenhouse Gases (“IWG”).
13
The derivation of these values
11
A metric ton is equivalent to 1.1 short tons. Results for emissions other than CO
2
are presented in short
tons.
12
DOE calculated emissions reductions relative to the no-new-standards case, which reflects key
assumptions in the Annual Energy Outlook 2023 (“AEO2023”). AEO2023 represents current Federal and
State legislation and final implementation of regulations as of the time of its preparation. See section IV.K
of this document for further discussion of AEO2023 assumptions that affect air pollutant emissions.
13
To monetize the benefits of reducing GHG emissions, this analysis uses the interim estimates presented
in the Technical Support Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates
13
is discussed in section IV.L of this document. For presentational purposes, the climate
benefits associated with the average SC-GHG at a 3-percent discount rate are estimated
to be $3.3 billion. DOE does not have a single central SC-GHG point estimate and it
emphasizes the importance and value of considering the benefits calculated using all four
sets of SC-GHG estimates.
DOE estimated the monetary health benefits of SO
2
and NO
X
emissions
reductions, using benefit-per-ton estimates from the Environmental Protection Agency,
14
as discussed in section IV.L of this document. DOE estimated the present value of the
health benefits would be $2.6 billion using a 7-percent discount rate, and $6.3 billion
using a 3-percent discount rate.
15
DOE is currently only monetizing health benefits from
changes in ambient fine particulate matter (PM
2.5
) concentrations from two precursors
(SO
2
and NO
X
), and from changes in ambient ozone from one precursor (for NO
X
), but
will continue to assess the ability to monetize other effects such as health benefits from
reductions in direct PM
2.5
emissions.
Table I.3 summarizes the monetized benefits and costs expected to result from the
amended standards for consumer clothes dryers. There are other important unquantified
effects, including certain unquantified climate benefits, unquantified public health
Under Executive Order 13990 published in February 2021 by the IWG. (“February 2021 SC-GHG TSD”).

shipped in 20282057.
* Climate benefits are calculated using four different estimates of the global SC-GHG (see section IV.L of
this document). For presentational purposes of this table, the climate benefits associated with the average
SC-GHG at a 3-percent discount rate are shown; however, DOE emphasizes the importance and value of
considering the benefits calculated using all four sets of SC-GHG estimates. To monetize the benefits of
reducing GHG emissions, this analysis uses the interim estimates presented in the Technical Support
Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates Under Executive Order
13990 published in February 2021 by the IWG.

monetizing (for SO

) PM

X
) ozone precursor health
15
benefits, but will continue to assess the ability to monetize other effects such as health benefits from
reductions in direct PM
2.5
emissions. See section IV.L of this document for more details.
Total and net benefits include those consumer, climate, and health benefits that can be quantified and monetized. For
presentation purposes, total and net benefits for both the 3-percent and 7-percent cases are presented using the average
SC-GHG with a 3-percent discount rate.
Costs include incremental equipment costs as well as installation costs.
‡‡ Operating Cost Savings are calculated based on the life cycle costs analysis and national impact analysis
as discussed in detail below. See sections IV.F and IV.H of this document. DOE’s national impact
analysis includes all impacts (both costs and benefits) along the distribution chain beginning with the
increased costs to the manufacturer to manufacture the product and ending with the increase in price
experienced by the consumer. DOE also separately conducts a detailed analysis on the impacts on
manufacturers (the MIA). See section IV.J of this document and chapter 12 of the direct final rule technical
support document (“TSD”). In the detailed MIA, DOE models manufacturers’ pricing decisions based on
assumptions regarding investments, conversion costs, cashflow, and margins. The MIA produces a range
of impacts, which is the rule’s expected impact on the INPV. The change in INPV is the present value of all
changes in industry cash flow, including changes in production costs, capital expenditures, and
manufacturer profit margins. Change in INPV is calculated using the industry weighted average cost of
capital value of 7.5 percent that is estimated in the MIA (see chapter 12 of the direct final rule TSD for a
complete description of the industry weighted average cost of capital). For consumer clothes dryers, those
values are -$144 million to -$120 million. DOE accounts for that range of likely impacts in analyzing
whether a TSL is economically justified. See section V.C of this document. DOE is presenting the range of
impacts to the INPV under two manufacturer markup scenarios: the Preservation of Gross Margin scenario,
which is the manufacturer markup scenario used in the calculation of Consumer Operating Cost Savings in
this table, and the Preservation of Operating Profit scenario, where DOE assumed manufacturers would not
be able to increase per-unit operating profit in proportion to increases in manufacturer production costs.
DOE includes the range of estimated change in INPV in the above table, drawing on the MIA explained
further in section IV.J of this document, to provide additional context for assessing the estimated impacts of
this direct final rule to society, including potential changes in production and consumption, which is
consistent with OMB’s Circular A-4 and E.O. 12866. If DOE were to include the INPV into the net benefit
calculation for this direct final rule, the net benefits would range from $19.96 billion to $19.98 billion at 3-
percent discount rate and would range from $9.06 billion to $9.08 billion at 7-percent discount rate.
Parentheses () indicate negative values.
The benefits and costs of the adopted standards can also be expressed in terms of
annualized values. The monetary values for the total annualized net benefits are (1) the
reduced consumer operating costs, minus (2) the increase in product purchase prices and
installation costs, plus (3) the value of climate and health benefits of emission reductions,
all annualized.
16
16
To convert the time-series of costs and benefits into annualized values, DOE calculated a present value in
2024, the year used for discounting the NPV of total consumer costs and savings. For the benefits, DOE
calculated a present value associated with each year’s shipments in the year in which the shipments occur
(e.g., 2020 or 2030), and then discounted the present value from each year to 2024. Using the present
value, DOE then calculated the fixed annual payment over a 30-year period, starting in the compliance
year, that yields the same present value.
16
The national operating cost savings are domestic private U.S. consumer monetary
savings that occur as a result of purchasing the covered products and are measured for the
lifetime of consumer clothes dryers shipped in 2028–2057. The benefits associated with
reduced emissions achieved as a result of the adopted standards are also calculated based
on the lifetime of consumer clothes dryers shipped in 2028–2057. Total benefits for both
the 3-percent and 7-percent cases are presented using the average GHG social costs with
a 3-percent discount rate. Estimates of SC-GHG values are presented for all four SC-
GHG discount rates in section IV.L of this document.
Table I.4 presents the total estimated monetized benefits and costs associated with
the adopted standards, expressed in terms of annualized values. The results under the
primary estimate are as follows.
Using a 7-percent discount rate for consumer benefits and costs and health
benefits from reduced NO
X
and SO
2
emissions, and the 3-percent discount rate case for
climate benefits from reduced GHG emissions, the estimated cost of the standards
adopted in this rule is $60.0 million per year in increased equipment costs, while the
estimated annual benefits are $971.4 million in reduced equipment operating costs,
$185.5 million in climate benefits, and $259.9 million in health benefits. In this case, the
net benefit would amount to $1,357 million per year.
Using a 3-percent discount rate for all benefits and costs, the estimated cost of the
standards is $57.2 million per year in increased equipment costs, while the estimated
annual benefits are $1,177 million in reduced operating costs, $185.5 million in climate
17
benefits, and $349.4 million in health benefits. In this case, the net benefit would amount

Note: This table presents the costs and benefits associated with consumer clothes dryers shipped in
2028−2057. These results include benefits to consumers which accrue after 2057 from the products
shipped in 2028−2057. The Primary, Low-Net-Benefits, and High-Net-Benefits estimates utilize
projections of energy prices from the AEO2023 Reference case, Low Economic Growth case, and High
Economic Growth case, respectively. In addition, incremental equipment costs reflect a medium decline
rate in the Primary Estimate, a constant rate in the Low-Net-Benefits Estimate, and a high decline rate in
the High-Net-Benefits Estimate. The methods used to derive projected price trends are explained in
sections IV.F.1 and IV.H.3 of this document. Note that the Benefits and Costs may not sum up to the Net
Benefits due to rounding.
* Climate benefits are calculated using four different estimates of the global SC-GHG (see section IV.L of
this document). For presentational purposes of this table, the climate benefits associated with the average
SC-GHG at a 3-percent discount rate are shown,
but DOE does not have a single central SC-GHG point estimate,
18
and it emphasizes the importance and value of considering the benefits calculated using all four sets of SC-
GHG estimates. To monetize the benefits of reducing GHG emissions, this analysis uses the interim
estimates presented in the Technical Support Document: Social Cost of Carbon, Methane, and Nitrous
Oxide Interim Estimates Under Executive Order 13990 published in February 2021 by the IWG.
** Health benefits are calculated using benefit-per-ton values for NO
X
and SO
2
. DOE is currently only
monetizing (for SO
2
and NO
X
) PM
2.5
precursor health benefits and (for NO
X
) ozone precursor health
benefits, but will continue to assess the ability to monetize other effects such as health benefits from
reductions in direct PM
2.5
emissions. See section IV.L of this document for more details.
Total benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with a
3-percent discount rate, but DOE does not have a single central SC-GHG point estimate.
‡ Costs include incremental equipment costs as well as installation costs.
‡‡ Operating Cost Savings are calculated based on the life cycle costs analysis and national impact analysis
as discussed in detail below. See sections IV.F and IV.H of this document. DOE’s national impact
analysis includes all impacts (both costs and benefits) along the distribution chain beginning with the
increased costs to the manufacturer to manufacture the product and ending with the increase in price
experienced by the consumer. DOE also separately conducts a detailed analysis on the impacts on
manufacturers (the MIA). See section IV.J of this document and chapter 12 of the direct final rule TSD. In
the detailed MIA, DOE models manufacturers’ pricing decisions based on assumptions regarding
investments, conversion costs, cashflow, and margins. The MIA produces a range of impacts, which is the
rule’s expected impact on the INPV. The change in INPV is the present value of all changes in industry
cash flow, including changes in production costs, capital expenditures, and manufacturer profit margins.
The annualized change in INPV is calculated using the industry weighted average cost of capital value of
7.5 percent that is estimated in the manufacturer impact analysis (see chapter 12 of the direct final rule TSD
for a complete description of the industry weighted average cost of capital). For consumer clothes dryers,
those values are -$12 million to -$10 million. DOE accounts for that range of likely impacts in analyzing
whether a TSL is economically justified. See section V.C of this document. DOE is presenting the range of
impacts to the INPV under two manufacturer markup scenarios: the Preservation of Gross Margin scenario,
which is the manufacturer markup scenario used in the calculation of Consumer Operating Cost Savings in
this table, and the Preservation of Operating Profit Markup scenario, where DOE assumed manufacturers
would not be able to increase per-unit operating profit in proportion to increases in manufacturer
production costs. DOE includes the range of estimated annualized change in INPV in the above table,
drawing on the MIA explained further in chapter 12 of this direct final rule TSD, to provide additional
context for assessing the estimated impacts of this direct final rule to society, including potential changes in
production and consumption, which is consistent with OMB’s Circular A-4 and E.O. 12866. If DOE were
to include the INPV into the annualized net benefit calculation for this direct final rule, the annualized net
benefits, using the primary estimate, would range from $1,642 million to $1,644 at 3-percent discount rate
and would range from $1,345 million to $1,347 million at 7-percent discount rate. Parentheses () indicate
negative values.
DOE’s analysis of the national impacts of the adopted standards is described in
sections IV.H, IV.K, and IV.L of this document.
D. Conclusion
DOE has determined that the Joint Agreement was submitted jointly by interested
persons that are fairly representative of relevant points of view, in accordance with 42
19
U.S.C. 6295(p)(4)(A). After considering the recommended standards and weighing the
benefits and burdens, DOE has determined that the recommended standards are in
accordance with 42 U.S.C. 6295(o), which contains the criteria for prescribing new or
amended standards. Specifically, the Secretary of Energy (“Secretary”) has determined
that the adoption of the recommended standards would result in the significant
conservation of energy and is the maximum improvement in energy efficiency that is
technologically feasible and economically justified. In determining whether the
recommended standards are economically justified, the Secretary has determined that the
benefits of the recommended standards exceed the burdens. The Secretary has further
concluded that the recommended standards, when considering the benefits of energy
savings, positive NPV of consumer benefits, emission reductions, the estimated monetary
value of the emissions reductions, and positive average LCC savings, would yield
benefits that outweigh the negative impacts on some consumers and on manufacturers,
including the conversion costs that could result in a reduction in INPV for manufacturers.
Using a 7-percent discount rate for consumer benefits and costs and NO
X
and SO
2
reduction benefits, and a 3-percent discount rate case for GHG social costs, the estimated
cost of the standards for consumer clothes dryers is $60.0 million per year in increased
product costs, while the estimated annual benefits are $971.4 million in reduced product
operating costs, $185.5 million in climate benefits, and $259.9 million in health benefits.
The net benefit amounts to $1,357 million per year. DOE notes that the net benefits are
20
substantial even in the absence of the climate benefits,
17
and DOE would adopt the same
standards in the absence of such benefits.
The significance of energy savings offered by a new or amended energy
conservation standard cannot be determined without knowledge of the specific
circumstances surrounding a given rulemaking.
18
For example, some covered products
and equipment have most of their energy consumption occur during periods of peak
energy demand. The impacts of these products on the energy infrastructure can be more
pronounced than products with relatively constant demand. Accordingly, DOE evaluates
the significance of energy savings on a case-by-case basis.
As previously mentioned, the standards are projected to result in estimated
national energy savings of 2.7 quads FFC, the equivalent of the primary annual energy
use of 18 million homes. In addition, they are projected to reduce cumulative CO
2
emissions by 57.1 Mt. Based on these findings, DOE has determined the energy savings
from the standard levels adopted in this direct final rule are “significant” within the
meaning of 42 U.S.C. 6295(o)(3)(B). A more detailed discussion of the basis for these
conclusions is contained in the remainder of this document and the accompanying TSD.
Under the authority provided by 42 U.S.C. 6295(p)(4), DOE is issuing this direct
final rule amending the energy conservation standards for consumer clothes dryers.

The information on climate benefits is provided in compliance with Executive Order 12866.

direct final rule. See 42 U.S.C. 6295(p)(4)(A)(i).
II.
Introduction
The following section briefly discusses the statutory authority underlying this
direct final rule, as well as some of the relevant historical background related to the
establishment of standards for consumer clothes dryers.
A. Authority
EPCA authorizes DOE to regulate the energy efficiency of a number of consumer
products and certain industrial equipment. Title III, Part B of EPCA established the
Energy Conservation Program for Consumer Products Other Than Automobiles. These
products include consumer clothes dryers, the subject of this document. (42 U.S.C.
6292(a)(8)) EPCA prescribed energy conservation standards for these products (42
U.S.C. 6295(g)(3)), and directed DOE to conduct future rulemakings to determine
whether to amend these standards. (42 U.S.C. 6295(g)(4)) EPCA further provides that,
not later than 6 years after the issuance of any final rule establishing or amending a
standard, DOE must publish either a notice of determination that standards for the
product do not need to be amended, or a NOPR including new proposed energy
conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C.
6295(m)(1))
22
The energy conservation program under EPCA consists essentially of four parts:
(1) testing, (2) labeling, (3) the establishment of Federal energy conservation standards,
and (4) certification and enforcement procedures. Relevant provisions of EPCA
specifically include definitions (42 U.S.C. 6291), test procedures (42 U.S.C. 6293),
labeling provisions (42 U.S.C. 6294), energy conservation standards (42 U.S.C. 6295),
and the authority to require information and reports from manufacturers (42 U.S.C.
6296).
Federal energy efficiency requirements for covered products established under
EPCA generally supersede State laws and regulations concerning energy conservation
testing, labeling, and standards. (42 U.S.C. 6297(a)(c)) DOE may, however, grant
waivers of Federal preemption in limited instances for particular State laws or
regulations, in accordance with the procedures and other provisions set forth under
EPCA. (42 U.S.C. 6297(d))
Subject to certain criteria and conditions, DOE is required to develop test
procedures to measure the energy efficiency, energy use, or estimated annual operating
cost of each covered product. (42 U.S.C. 6295(o)(3)(A) and 42 U.S.C. 6295(r))
Manufacturers of covered products must use the prescribed DOE test procedure as the
basis for certifying to DOE that their products comply with the applicable energy
conservation standards adopted under EPCA and when making representations to the
public regarding the energy use or efficiency of those products. (42 U.S.C. 6293(c) and
6295(s)) Similarly, DOE must use these test procedures to determine whether the
products comply with standards adopted pursuant to EPCA. (42 U.S.C. 6295(s)) The
23
DOE test procedures for consumer clothes dryers appear at title 10 of the Code of Federal
Regulations (“CFR”) part 430, subpart B, appendix D1 (“appendix D1”) and appendix
D2 (“appendix D2”).
DOE must follow specific statutory criteria for prescribing new or amended
standards for covered products, including consumer clothes dryers. Any new or amended
standard for a covered product must be designed to achieve the maximum improvement
in energy efficiency that the Secretary determines is technologically feasible and
economically justified. (42 U.S.C. 6295(o)(2)(A) Furthermore, DOE may not adopt any
standard that would not result in the significant conservation of energy. (42 U.S.C.
6295(o)(3)(B))
Moreover, DOE may not prescribe a standard if DOE determines by rule that the
standard is not technologically feasible or economically justified. (42 U.S.C.
6295(o)(3)(B)) In deciding whether a proposed standard is economically justified, DOE
must determine whether the benefits of the standard exceed its burdens. (42 U.S.C.
6295(o)(3)(B)) DOE must make this determination after receiving comments on the
proposed standard, and by considering, to the greatest extent practicable, the following
seven statutory factors:
(1) The economic impact of the standard on manufacturers and consumers of the
products subject to the standard;
24
(2) The savings in operating costs throughout the estimated average life of the
covered products in the type (or class) compared to any increase in the price,
initial charges, or maintenance expenses for the covered products that are
likely to result from the standard;
(3) The total projected amount of energy (or as applicable, water) savings likely to
result directly from the standard;
(4) Any lessening of the utility or the performance of the covered products likely
to result from the standard;
(5) The impact of any lessening of competition, as determined in writing by the
Attorney General, that is likely to result from the standard;
(6) The need for national energy and water conservation; and
(7) Other factors the Secretary considers relevant.
(42 U.S.C. 6295(o)(2)(B)(i)(I)(VII))
Further, EPCA, as codified, establishes a rebuttable presumption that a standard is
economically justified if the Secretary finds that the additional cost to the consumer of
purchasing a product complying with an energy conservation standard level will be less
than three times the value of the energy savings during the first year that the consumer
25
will receive as a result of the standard, as calculated under the applicable test procedure.
(42 U.S.C. 6295(o)(2)(B)(iii))
EPCA, as codified, also contains what is known as an “anti-backsliding”
provision, which prevents the Secretary from prescribing any amended standard that
either increases the maximum allowable energy use or decreases the minimum required
energy efficiency of a covered product. (42 U.S.C. 6295(o)(1)) Also, the Secretary may
not prescribe an amended or new standard if interested persons have established by a
preponderance of evidence that the standard is likely to result in the unavailability in the
United States in any covered product type (or class) of performance characteristics
(including reliability), features, sizes, capacities, and volumes that are substantially the
same as those generally available in the United States. (42 U.S.C. 6295(o)(4))
EPCA specifies requirements when promulgating an energy conservation standard
for a covered product that has two or more subcategories. A rule prescribing an energy
conservation standard for a type (or class) of product must specify a different standard
level for a type or class of products that has the same function or intended use if DOE
determines that products within such group (A) consume a different kind of energy from
that consumed by other covered products within such type (or class); or (B) have a
capacity or other performance-related feature which other products within such type (or
class) do not have and such feature justifies a higher or lower standard. (42 U.S.C.
6295(q)(1)) In determining whether a performance-related feature justifies a different
standard for a group of products, DOE consider such factors as the utility to the consumer
of such a feature and other factors DOE deems appropriate. Id. Any rule prescribing such
26
a standard must include an explanation of the basis on which such higher or lower level
was established. (42 U.S.C. 6295(q)(2))
Additionally, pursuant to the amendments contained in the Energy Independence
and Security Act of 2007 (“EISA 2007”), Pub. L. 110-140, final rules for new or
amended energy conservation standards promulgated after July 1, 2010, are required to
address standby mode and off mode energy use. (42 U.S.C. 6295(gg)(3)) Specifically,
when DOE adopts a standard for a covered product after that date, it must, if justified by
the criteria for adoption of standards under EPCA (42 U.S.C. 6295(o)), incorporate
standby mode and off mode energy use into a single standard, or, if that is not feasible,
adopt a separate standard for such energy use for that product. (42 U.S.C.
6295(gg)(3)(A)(B)) DOE’s current test procedures for consumer clothes dryers address
standby mode and off mode energy use, as do the amended standards adopted in this
direct final rule.
Finally, EISA 2007 amended EPCA, in relevant part, to grant DOE authority to
directly issue a final rule (i.e., a “direct final rule”) establishing an energy conservation
standard upon receipt of a statement submitted jointly by interested persons that are fairly
representative of relevant points of view (including representatives of manufacturers of
covered products, States, and efficiency advocates), as determined by the Secretary, that
contains recommendations with respect to an energy or water conservation standard. (42
U.S.C. 6295(p)(4)) Pursuant to 42 U.S.C. 6295(p)(4), the Secretary must also determine
whether a jointly submitted recommendation for an energy or water conservation
standard satisfies 42 U.S.C. 6295(o) or 42 U.S.C. 6313(a)(6)(B), as applicable.
27
The direct final rule must be published simultaneously with a NOPR that proposes
an energy or water conservation standard that is identical to the standard established in
the direct final rule, and DOE must provide a public comment period of at least 110 days
on this proposal. (42 U.S.C. 6295(p)(4)(A)–(B)) While DOE typically provides a
comment period of 60 days on proposed standards, for a NOPR accompanying a direct
final rule, DOE provides a comment period of the same length as the comment period on
the direct final rulei.e., 110 days. Based on the comments received during this period,
the direct final rule will either become effective, or DOE will withdraw it not later than
120 days after its issuance if: (1) one or more adverse comments is received, and (2)
DOE determines that those comments, when viewed in light of the rulemaking record
related to the direct final rule, may provide a reasonable basis for withdrawal of the direct
final rule under 42 U.S.C. 6295(o). (42 U.S.C. 6295(p)(4)(C)) Receipt of an alternative
joint recommendation may also trigger a DOE withdrawal of the direct final rule in the
same manner. (Id.)
DOE has previously explained its interpretation of its direct final rule authority. In
a final rule amending the Department’s “Procedures, Interpretations and Policies for
Consideration of New or Revised Energy Conservation Standards for Consumer
Products” at 10 CFR part 430, subpart C, appendix A (“Process Rule” or “appendix A”),
DOE noted that it may issue standards recommended by interested persons that are fairly
representative of relative points of view as a direct final rule when the recommended
standards are in accordance with 42 U.S.C. 6295(o) or 42 U.S.C. 6313(a)(6)(B), as
applicable. 86 FR 70892, 70912 (Dec. 13, 2021). But the direct final rule provision in
EPCA does not impose additional requirements applicable to other standards
28
rulemakings, which is consistent with the unique circumstances of rules issued through
consensus agreements under DOE’s direct final rule authority. Id. DOE's discretion
remains bounded by its statutory mandate to adopt a standard that results in the maximum
improvement in energy efficiency that is technologically feasible and economically
justifieda requirement found in 42 U.S.C. 6295(o). Id. As such, DOE’s review and
analysis of the Joint Agreement is limited to whether the recommended standards satisfy
the criteria in 42 U.S.C. 6295(o).
B. Background
1. Current Standards
In a direct final rule published on April 21, 2011, (“April 2011 Direct Final
Rule”) DOE prescribed the current energy conservation standards for consumer clothes
dryers manufactured on and after January 1, 2015. 76 FR 22454.
19
These standards are
set forth in DOE’s regulations at 10 CFR 430.32(h)(3) and are shown in Table II.1.
These standards are consistent with a prior joint proposal submitted to DOE by interested
parties representing manufacturers, energy and environmental advocates, and consumer
groups.
20
The current standards are defined in terms of a minimum allowable CEF, as
measured according to appendix D1. Even though DOE maintained the same energy
19
DOE published a confirmation of effective date and compliance date for the direct final rule on August
24, 2011. 76 FR 52854.

efficiency descriptor for both appendix D1 and appendix D2, DOE notes that the CEF
values are not equivalent because of the extensive differences in test methods.
21
To avoid
potential confusion that would result from using the same efficiency descriptor for both
test procedures as it relates to the standards discussed in this document, DOE is including
a “D1” or “D2” subscript when referring to the appendix D1 CEF and appendix D2 CEF,
respectively (“CEF
D1
” and “CEF
D2
”).

2. Current Test Procedure
On October 8, 2021, DOE published a final rule for the test procedure rulemaking
(86 FR 56608) (the “October 2021 TP Final Rule”), in which it amended appendix D1
and appendix D2, both entitled “Uniform Test Method for Measuring the Energy
Consumption of Clothes Dryers,” to provide additional detail in response to questions
from manufacturers and test laboratories, including additional detail regarding the testing
of “connected” models, dryness level selection, and the procedures for maintaining the
21
While the current standards are based on CEF as determined in accordance with appendix D1,
manufacturers are permitted to use the appendix D2 test procedure to comply with the current standards, as
long as they use a single appendix for all representations. Beginning on the compliance date of the
amended standards established by this direct final rule, manufacturers will be required to use appendix D2
to comply with the amended standards.
30
required heat input rate for gas consumer clothes dryers; additional detail for the test
procedures for performing inactive and off mode power measurements; specifications for
the final moisture content (“FMC”) required for testing automatic termination control
dryers; specification of a narrower scale resolution for the weighing scale used to
determine moisture content of test loads; and specification that the test load must be
weighed within 5 minutes after a test cycle has terminated. In addition, as part of the
October 2021 TP Final Rule, DOE amended the test procedures to update the estimated
number of annual use cycles for consumer clothes dryers; provide further direction for
additional provisions within the test procedures; specify rounding requirements for all
reported values; apply consistent use of nomenclature and correct typographical errors;
remove obsolete sections of the test procedures, including appendix D; and update the
reference to the applicable industry test procedure to the version certified by the
American National Standards Institute (“ANSI”). 86 FR 56608, 56610.
DOE’s current energy conservation standards for consumer clothes dryers are
expressed in terms of CEF
D1
. (See 10 CFR 430.32(h)(3).) Appendix D1 tests timed
drying cycles, and accounts for clothes dryers with automatic termination controls by
applying a higher field use factor to units that have this feature. Appendix D2 tests
“normal” automatic termination cycles and more accurately measures the effects of
automatic cycle termination.
EPCA authorizes DOE to design test procedures that measure energy efficiency,
energy use, water use, or estimated annual operating cost of a covered product during a
representative average use cycle or period of use. (42 U.S.C. 6293(b)(3)) The appendix
31
D2 test procedure, which is required for use to demonstrate compliance with the amended
energy conservation standards established in this direct final rule, measures the energy
consumption of a representative use cycle that dries a load of laundry from an initial
moisture content of 57.5 percent to an FMC of less than 2 percent. 86 FR 56624-56625.
For timer clothes dryers, the test load is dried until the FMC is between 1 and 2.5 percent
of the bone-dry weight of the test load. The measured energy consumption is then
normalized to determine the energy consumption required to dry the test load to 2-percent
FMC, with a field use factor applied to account for the over-drying energy consumption.
For automatic termination control clothes dryers, appendix D2 specifies that a “normal”
program be selected for the test cycle, and for clothes dryers that do not have a “normal”
program, the cycle recommended by the manufacturer for drying cotton or linen shall be
selected. If the drying temperature and drying level settings can be chosen independently
of the program, they shall be set at the maximum drying temperature setting, and at a
“normal” or “medium” dryness level setting. The test is considered valid if the FMC of
the test load is 2 percent or less after the completion of the test cycle. If the FMC is
greater than 2 percent, the test is considered invalid and a new run shall be conducted
using the highest dryness level setting.
The current 2-percent FMC requirement using the DOE test cloth was adopted as
representative of approximately 5-percent FMC for “real-world” clothing, based on data
submitted in a joint petition for rulemaking.
22
DOE determined in the final rule published
22
The petition was submitted by AHAM, Whirlpool Corporation, General Electric Company, Electrolux,
LG Electronics, Inc., BSH, Alliance Laundry Systems, Viking Range, Sub-Zero Wolf, Friedrich A/C, U-
Line, Samsung, Sharp Electronics, Miele, Heat Controller, AGA Marvel, Brown Stove, Haier, Fagor
32
on August 14, 2013, that established the appendix D2 Test procedure that the specified 2-
percent FMC using the DOE test load was representative of consumer expectations for
dryness of clothing in field use. 78 FR 49608, 49620–49622, 49610–49611. DOE did not
amend the FMC requirements in the October 2021 TP Final Rule. 86 FR 56626.
DOE has conducted the rulemaking analysis for this direct final rule based on
CEF
D2
because compliance with the amended energy conservation standards established
in this direct final rule must be determined based on the use of appendix D2. DOE
discusses additional details in section IV.C.1 of this document about how it developed the
engineering baseline, in terms of CEF
D2
, from the current consumer clothes dryer
standards that are in terms of CEF
D1
.
3. The Joint Agreement
On September 25, 2023, DOE received a joint statement of recommended
standards (i.e., the Joint Agreement) for various home appliance products, including
consumer clothes dryers, submitted jointly by groups representing manufacturers, energy
and environmental advocates, consumer groups, and a utility.
23
In addition to the
America, Airwell Group, Arcelik, Fisher & Paykel, Scotsman Ice, Indesit, Kuppersbusch, Kelon, and
DeLonghi, American Council for an Energy Efficient Economy, Appliance Standards Awareness Project,
Natural Resources Defense Council, Alliance to Save Energy, Alliance for Water Efficiency, Northwest
Power and Conservation Council, and Northeast Energy Efficiency Partnerships, Consumer Federation of
America and the National Consumer Law Center. See Docket No. EERE2011BT–TP– 0054, No. 3.
23
The signatories to the Joint Agreement include AHAM, American Council for an Energy-Efficient
Economy, Alliance for Water Efficiency, Appliance Standards Awareness Project, Consumer Federation of
America, Consumer Reports, Earthjustice, National Consumer Law Center, Natural Resources Defense
Council, Northwest Energy Efficiency Alliance, and Pacific Gas and Electric Company. Members of
AHAM’s Major Appliance Division that make the affected products include: Alliance Laundry Systems,
LLC; Asko Appliances AB; Beko US Inc.; Brown Stove Works, Inc.; BSH Home Appliances Corporation;
Danby Products, Ltd.; Electrolux Home Products, Inc.,; Elicamex S.A. de C.V.; Faber; Fotile America; GE
Appliances, a Haier Company; L’Atelier Paris Haute Design LLG; LG Electronics; Liebherr USA, Co.;
33
recommended standards for consumer clothes dryers, the Joint Agreement also included
separate recommendations for several other covered products.
24
And, while
acknowledging that DOE may implement these recommendations in separate
rulemakings, the Joint Agreement also stated that the recommendations were
recommended as a complete package and each recommendation is contingent upon the
other parts being implemented. DOE understands this to mean that the Joint Agreement
is contingent upon DOE initiating rulemaking processes to adopt all of the recommended
standards in the agreement. That is distinguished from an agreement where issuance of an
amended energy conservation standard for a covered product is contingent on issuance of
amended energy conservation standards for the other covered products. If the Joint
Agreement were so construed, it would conflict with the anti-backsliding provision in 42
U.S.C. 6295(o)(1), because it would imply the possibility that, if DOE were unable to
issue an amended standard for a certain product, it would have to withdraw a previously
issued standard for one of the other products. The anti-backsliding provision, however,
prevents DOE from withdrawing or amending an energy conservation standard to be less
stringent. As a result, DOE will be proceeding with individual rulemakings that will
evaluate each of the recommended standards separately under the applicable statutory
criteria.

24
The Joint Agreement contained recommendations for 6 covered products: refrigerators, refrigerator-
freezers, and freezers; clothes washers; clothes dryers; dishwashers; cooking products; and miscellaneous
refrigeration products.
34
A court decision issued after DOE received the Joint Agreement is also relevant
to this rule. On March 17, 2022, various States filed a petition seeking review of a final
rule revoking two final rules that established product classes for residential dishwashers
with a cycle time for the normal cycle of 60 minutes or less, top-loading residential
clothes washers (“RCWs”) and certain classes of consumer clothes dryers with a cycle
time of less than 30 minutes, and front-loading RCWs with a cycle time of less than 45
minutes (collectively, “short cycle product classes”). The petitioners argued that the final
rule revoking the short cycle product classes violated EPCA and was arbitrary and
capricious. On January 8, 2024, the United States Court of Appeals for the Fifth Circuit
granted the petition for review and remanded the matter to DOE for further proceedings
consistent with the Fifth Circuit’s opinion. See Louisiana v. United States Department of
Energy, 90 F.4th 461 (5th Cir. 2024). On February 14, 2024, following the Fifth Circuit’s
decision in Louisiana v. United States Department of Energy, DOE received a second
joint statement from this same group of stakeholders in which the signatories reaffirmed
the Joint Agreement, stating that the recommended standards represent the maximum
levels of efficiency that are technologically feasible and economically justified.
25
In the
letter, the signatories clarified that “short-cycle” product classes for RCWs, clothes
dryers, and dishwashers did not exist at the time that the signatories submitted their
recommendations and it is their understanding that these classes also do not exist at the
current time. Accordingly, the parties clarified that the Joint Agreement did not address
short-cycle product classes. The signatories also stated that they did not anticipate that the

recommended energy conservation standards in the Joint Agreement will negatively
affect features or performance, including cycle time, for consumer clothes dryers.
The Joint Agreement recommends amended standard levels for consumer clothes
dryers as presented in Table II.2. (Joint Agreement, No. 55 at p. 9)

When the Joint Agreement was submitted, DOE was conducting a rulemaking to
consider amending the standards for consumer clothes dryers. As part of that process,
DOE published a NOPR and announced a public meeting on August 23, 2022 (“August

consistent with its obligations under EPCA and the Administrative Procedure Act
(“APA”). 87 FR 51734. DOE subsequently held a public webinar on September 13,
2022, to discuss and receive comments on the NOPR TSD.
Although DOE is adopting the Joint Agreement as a direct final rule and no
longer proceeding with its prior rulemaking, DOE did consider relevant comments, data,
and information obtained during that rulemaking process in determining whether the
recommended standards from the Joint Agreement are in accordance with 42 U.S.C.
6295(o). Any discussion of comments, data, or information in this direct final rule that
were obtained during DOE’s prior rulemaking will include a parenthetical reference that
provides the location of the item in the public record.

III.
General Discussion
DOE is issuing this direct final rule after determining that the recommended
standards submitted in the Joint Agreement meet the requirements in 42 U.S.C.
6295(p)(4). More specifically, DOE has determined that the recommended standards
were submitted by interested persons that are fairly representative of relevant points of
view and the recommended standards satisfy the criteria in 42 U.S.C. 6295(o).
28
The parenthetical reference provides a reference for information located in the docket of DOE’s

(commenter name, comment docket ID number at page of that document).
37
On March 17, 2022, various states filed a petition seeking review of a final rule
revoking two final rules that established product classes for residential dishwashers with
a cycle time for the normal cycle of 60 minutes or less, top-loading RCWs and certain
classes of consumer clothes dryers with a cycle time of less than 30 minutes, and front-
loading RCWs with a cycle time of less than 45 minutes (collectively, “short cycle
product classes”). The petitioners argued that the final rule revoking the short cycle
product classes violated EPCA and was arbitrary and capricious. On January 8, 2024, the
United States Court of Appeals for the Fifth Circuit granted the petition for review and
remanded the matter to DOE for further proceedings consistent with the Fifth Circuit’s
opinion. See Louisiana v. United States Department of Energy, 90 F.4th 461 (5th Cir.
2024)
Following the Fifth Circuit’s decision, the signatories to the Joint Agreement
submitted a second letter to DOE, which stated that Joint Recommendation did not
“address” “short-cycle product classes.”
29
That is because, as the letter explained, such
product classes “did not exist” at the time of the Joint Agreement.
In a recently issued Request for Information,
30
DOE is commencing a rulemaking
process on remand from the Fifth Circuit (the Remand Proceeding) by soliciting further
information, relevant to the issues identified by the Fifth Circuit, regarding any short
cycle product classes. In that Remand Proceeding, DOE will conduct the analysis

required by 42 U.S.C. 6295(q)(1)(B) to determine whether any short-cycle products have
a “capacity or other performance-related feature [that] . . . justifies a higher or lower
standard from that which applies (or will apply) to other products. .....
The current standards applicable to any products within the scope of that
proceeding remain unchanged by this rule. See 10 CFR 430.32(g). Consistent with the
Joint Parties’ letter, short-cycle products are not subject to the amended standards
adopted by this direct final rule. If the short-cycle products that DOE will consider in the
Remand Proceeding were subject to these standards, that would have the practical effect
of limiting the options available in the Remand Proceeding. That is because EPCA’s anti-
backsliding provision precludes DOE from prescribing any amended standard “which
increases the maximum allowable energy use” of a covered product. 42
U.S.C. 6295(o)(1). Accordingly, were the products at issue in the Remand Proceeding
also subject to the amended standards adopted here, the Department could only reaffirm
the standards adopted in this direct final rule or adopt more stringent standards.
The Joint Agreement specifies the product classes for consumer clothes dryers:
electric, standard; electric, compact; vented electric, compact; vented gas, standard;
vented gas, compact; ventless electric, compact; and ventless electric, combination
washer-dryer. Although these product classes were not further divided by cycle time,
DOE understands them to exclude vented electric standard-size clothes dryers and vented
gas standard-size clothes dryers with a cycle time of less than 30 minutes, when tested
according to appendix D2. As previously noted, any such “short-cycle” consumer clothes
39
dryers will be considered in the Remand Proceeding; the current standards applicable to
such “short-cycle” consumer clothes dryers are unchanged by this rule.
Under the direct final rule authority at 42 U.S.C. 6295(p)(4), DOE evaluates
whether recommended standards are in accordance with criteria contained in 42 U.S.C.
6295(o). DOE does not have the authority to revise recommended standards submitted
under the direct final rule provision in EPCA. Therefore, DOE did not analyze any
additional product classes beyond those product classes included in the Joint Agreement.
That is, DOE has not separately considered or established amended standards applicable
to any short-cycle product classes. In the event that DOE establishes short-cycle product
classes, pursuant to the rulemaking on remand from the Fifth Circuit, DOE will
necessarily consider what amended standards ought to apply to any such product classes
and will do so in conformance with EPCA.
DOE notes that the data and analysis used to support this direct final rule includes
information for vented electric standard-size clothes dryers and vented gas standard-size
clothes dryers that is not distinguished by cycle time and is representative of all consumer
clothes dryers currently on the market today. To the extent that any short cycle product
classes were included in this data and analysis, DOE believes the amount of such data is
negligible.
40
A. Scope of Coverage
Before discussing how the Joint Agreement meets the requirements for issuing a
direct final rule, it is important to clarify the scope of coverage for the recommended
standards. EPCA does not define the term “clothes dryer.” (See 42 U.S.C. 6291) DOE has
defined an “electric clothes dryer” as a cabinet-like appliance designed to dry fabrics in a
tumble-type drum with forced air circulation. The heat source is electricity and the drum
and blower(s) are driven by an electric motor(s). 10 CFR 430.2. DOE has defined a “gas
clothes dryer” as a cabinet-like appliance designed to dry fabrics in a tumble-type drum
with forced air circulation. The heat source is gas and the drum and blower(s) are driven
by an electric motor(s). Id. This direct final rule covers consumer clothes dryers, i.e.,
those consumer products that meet the definitions of “electric clothes dryer” and “gas
clothes dryer,” as codified at 10 CFR 430.2.
See section IV.A.1 of this document for discussion of the product classes analyzed
in this direct final rule.
B. Fairly Representative of Relevant Points of View
Under the direct final rule provision in EPCA, recommended energy conservation
standards must be submitted by interested persons that are fairly representative of
relevant points of view (including representatives of manufacturers of covered products,
States, and efficiency advocates) as determined by DOE. (42 U.S.C. 6295(p)(4)(A)) With
respect to this requirement, DOE notes that the Joint Agreement included a trade
41
association, AHAM, which represents 11 manufacturers of consumer clothes dryers.
31
The Joint Agreement also included environmental and energy-efficiency advocacy
organizations, consumer advocacy organizations, and a gas and electric utility company.
Additionally, DOE received a letter in support of the Joint Agreement from the States of
New York, California, and Massachusetts (See comment No. 56). DOE also received a
letter in support of the Joint Agreement from a gas and electric utility, SDG&E, and an
electric utility, SCE (See comment No. 57). As a result, DOE has determined that the
Joint Agreement was submitted by interested persons who are fairly representative of
relevant points of view.
C. Technological Feasibility
1. General
In each energy conservation standards rulemaking, DOE conducts a screening
analysis based on information gathered on all current technology options and prototype
designs that could improve the efficiency of the products or equipment that are the
subject of the rulemaking. In evaluating the recommended standards proposed in the
Joint Agreement, DOE conducted the same analysis. As the first step in such an analysis,
DOE develops a list of technology options for consideration in consultation with
manufacturers, design engineers, and other interested parties. DOE then determines
which of those means for improving efficiency are technologically feasible. DOE
31
These companies include: Alliance Laundry Systems, LLC; Beko US Inc.; BSH Home Appliances
Corporation; Danby Products, Ltd.; Electrolux Home Products, Inc.; GE Appliances, a Haier Company; LG
Electronics; Midea America Corp.; Miele, Inc.; Samsung Electronics America Inc.; and Whirlpool
Corporation.
42
considers technologies incorporated in commercially available products or in working
prototypes to be technologically feasible. Sections 6(b)(3)(i) and 7(b)(1) of appendix A.
After DOE has determined that particular technology options are technologically
feasible, it further evaluates each technology option in light of the following additional
screening criteria: (1) practicability to manufacture, install, and service; (2) adverse
impacts on product utility or availability; (3) adverse impacts on health or safety; and (4)
unique-pathway proprietary technologies. Sections 7(b)(2)(5) of appendix A. Section
IV.
B of this document discusses the results of the screening analysis for consumer clothes
dryers, particularly the designs DOE considered, those it screened out, and those that are
the basis for the standards considered in this rulemaking. For further details on the
screening analysis for this rulemaking, see chapter 4 of the direct final rule TSD.
2. Maximum Technologically Feasible Levels
When DOE proposes to adopt an amended standard for a type or class of covered
product, it must determine the maximum improvement in energy efficiency or maximum
reduction in energy use that is technologically feasible for such product. (42 U.S.C.
6295(o)(2)(A)) Accordingly, in the engineering analysis, DOE determined the maximum
technologically feasible (“max-tech”) improvements in energy efficiency for consumer
clothes dryers using the design parameters for the most efficient products available on the
market or in working prototypes. The max-tech levels that DOE determined for this
rulemaking are described in section IV.C of this document and in chapter 5 of the direct
final rule TSD.
43
D. Energy Savings
1. Determination of Savings
For each TSL considered, DOE projected energy savings from application of the
TSL to consumer clothes dryers purchased in the 30-year period that begins in the year of
compliance with the amended standards (2027–2056 for all TSLs except the
Recommended TSL (i.e., TSL 3) and 2028–2057 for TSL 3).
32
The savings are measured
over the entire lifetime of consumer clothes dryers purchased in the 30-year analysis
period. DOE quantified the energy savings attributable to each TSL as the difference in
energy consumption between each standards case and the no-new-standards case. The
no-new-standards case represents a projection of energy consumption that reflects how
the market for a product would likely evolve in the absence of amended energy
conservation standards.
DOE used its national impact analysis (“NIA”) spreadsheet models to estimate
national energy savings (“NES”) from potential amended standards for consumer clothes
dryers. The NIA spreadsheet model (described in section IV.H of this document)
calculates energy savings in terms of site energy, which is the energy directly consumed
by products at the locations where they are used. For electricity, DOE reports national
energy savings in terms of primary energy savings, which is the savings in the energy that
is used to generate and transmit the site electricity. For natural gas, the primary energy
savings are considered to be equal to the site energy savings. DOE also calculates NES
in terms of FFC energy savings. The FFC metric includes the energy consumed in

DOE also presents a sensitivity analysis that considers impacts for products shipped in a 9-year period.
44
extracting, processing, and transporting primary fuels (i.e., coal, natural gas, petroleum
fuels), and thus presents a more complete picture of the impacts of energy conservation
standards.
33
DOE’s approach is based on the calculation of an FFC multiplier for each of
the energy types used by covered products or equipment. For more information on FFC
energy savings, see section IV.H.2 of this document.
2. Significance of Savings
To adopt any new or amended standards for a covered product including through
a direct final rule, DOE must determine that such action would result in significant
energy savings. (42 U.S.C. 6295(o)(3)(B))
The significance of energy savings offered by a new or amended energy
conservation standard cannot be determined without knowledge of the specific
circumstances surrounding a given rulemaking.
34
For example, some covered products
and equipment have most of their energy consumption occur during periods of peak
energy demand. The impact of these products on the energy infrastructure can be more
pronounced than products with relatively constant demand. Accordingly, DOE evaluates
the significance of energy savings on a case-by-case basis, taking into account the
significance of cumulative FFC national energy savings, the cumulative FFC emissions
reductions, and the need to confront the global climate crisis, among other factors.
33
The FFC metric is discussed in DOE’s statement of policy and notice of policy amendment. 76 FR
51282 (Aug. 18, 2011), as amended at 77 FR 49701 (Aug. 17, 2012).

Procedures, Interpretations, and Policies for Consideration in New or Revised Energy Conservation
Standards and Test Procedures for Consumer Products and Commercial/Industrial Equipment, 86 FR
70892, 70901 (Dec. 13, 2021).
45
As stated, the standard levels adopted in this direct final rule are projected to
result in national energy savings of 2.7 quads, the equivalent of the electricity use of 18
million homes in one year. Based on the amount of FFC savings, the corresponding
reduction in emissions, and the need to confront the global climate crisis, DOE has
determined the energy savings from the standard levels adopted in this direct final rule
are “significant” within the meaning of 42 U.S.C. 6295(o)(3)(B).
E. Economic Justification
1. Specific Criteria
As noted previously, EPCA provides seven factors to be evaluated in determining
whether a potential energy conservation standard is economically justified. (42 U.S.C.
6295(o)(2)(B)(i)(I)(VII)) The following sections discuss how DOE has addressed each
of those seven factors in this direct final rulemaking.
a. Economic Impact on Manufacturers and Consumers
In determining the impacts of amended standards on manufacturers, DOE
conducts an MIA, as discussed in section IV.J of this document. DOE first uses an
annual cash-flow approach to determine the quantitative impacts. This step includes both
a short-term assessment—based on the cost and capital requirements during the period
between when a regulation is issued and when entities must comply with the regulation
and a long-term assessment over a 30-year period. The industry-wide impacts analyzed
include (1) INPV, which values the industry on the basis of expected future cash flows;
(2) cash flows by year; (3) changes in revenue and income; and (4) other measures of
impact, as appropriate. Second, DOE analyzes and reports the impacts on different types
46
of manufacturers, including impacts on small manufacturers. Third, DOE considers the
impact of standards on domestic manufacturer employment and manufacturing capacity,
as well as the potential for standards to result in plant closures and loss of capital
investment. Finally, DOE takes into account cumulative impacts of various DOE
regulations and other regulatory requirements on manufacturers.
For individual consumers, measures of economic impact include the changes in
LCC and PBP associated with new or amended standards. These measures are discussed
further in the following section. For consumers in the aggregate, DOE also calculates the
national net present value of the consumer costs and benefits expected to result from
particular standards. DOE also evaluates the impacts of potential standards on
identifiable subgroups of consumers that may be affected disproportionately by a
standard.
b. Savings in Operating Costs Compared to Increase in Price (LCC and PBP)
EPCA requires DOE to consider the savings in operating costs throughout the
estimated average life of the covered product in the type (or class) compared to any
increase in the price of, or in the initial charges for, or maintenance expenses of, the
covered product that are likely to result from a standard. (42 U.S.C. 6295(o)(2)(B)(i)(II))
DOE conducts this comparison in its LCC and PBP analysis.
The LCC is the sum of the purchase price of a product (including its installation)
and the operating cost (including energy, maintenance, and repair expenditures)
discounted over the lifetime of the product. The LCC analysis requires a variety of
47
inputs, such as product prices, product energy consumption, energy prices, maintenance
and repair costs, product lifetime, and discount rates appropriate for consumers. To
account for uncertainty and variability in specific inputs, such as product lifetime and
discount rate, DOE uses a distribution of values, with probabilities attached to each value.
The PBP is the estimated amount of time (in years) it takes consumers to recover
the increased purchase cost (including installation) of a more efficient product through
lower operating costs. DOE calculates the PBP by dividing the change in purchase cost
due to a more stringent standard by the change in annual operating cost for the year that
standards are assumed to take effect.
For its LCC and PBP analysis, DOE assumes that consumers will purchase the
covered products in the first year of compliance with new or amended standards. The
LCC savings for the considered efficiency levels are calculated relative to the case that
reflects projected market trends in the absence of new or amended standards. DOE’s
LCC and PBP analysis is discussed in further detail in section IV.F of this document.
c. Energy Savings
Although significant conservation of energy is a separate statutory requirement
for adopting an energy conservation standard, EPCA requires DOE, in determining the
economic justification of a standard, to consider the total projected energy savings that
are expected to result directly from the standard. (42 U.S.C. 6295(o)(2)(B)(i)(III)) As
discussed in section IV.H of this document, DOE uses the NIA spreadsheet models to
project national energy savings.
48
d. Lessening of Utility or Performance of Products
In evaluating design options and the impact of the recommended standard levels,
DOE evaluates potential standards that would not lessen the utility or performance of the
considered products. (42 U.S.C. 6295(o)(2)(B)(i)(IV)) Based on data available to DOE,
the standards adopted in this document would not reduce the utility or performance of the
products under consideration in this rulemaking.
e. Impact of Any Lessening of Competition
EPCA directs DOE to consider the impact of any lessening of competition, as
determined in writing by the Attorney General, that is likely to result from a standard.
(42 U.S.C. 6295(o)(2)(B)(i)(V)) It also directs the Attorney General to determine the
impact, if any, of any lessening of competition likely to result from a standard and to
transmit such determination to the Secretary within 60 days of the publication of a
proposed rule, together with an analysis of the nature and extent of the impact. (42
U.S.C. 6295(o)(2)(B)(ii)) DOE will transmit a copy of this direct final rule to the
Attorney General with a request that the Department of Justice (“DOJ”) provide its
determination on this issue. DOE will consider DOJ's comments on the rule in
determining whether to withdraw the direct final rule. DOE will also publish and respond
to the DOJ's comments in the Federal Register in a separate document.
49
f. Need for National Energy Conservation
DOE also considers the need for national energy and water conservation in
determining whether a new or amended standard is economically justified. (42 U.S.C.
6295(o)(2)(B)(i)(VI)) The energy savings from the adopted standards are likely to
provide improvements to the security and reliability of the Nation’s energy system.
Reductions in the demand for electricity also may result in reduced costs for maintaining
the reliability of the Nation’s electricity system. DOE conducts a utility impact analysis
to estimate how standards may affect the Nation’s needed power generation capacity, as
discussed in section IV.M of this document.
DOE maintains that environmental and public health benefits associated with the
more efficient use of energy are important to take into account when considering the need
for national energy conservation. The adopted standards are likely to result in
environmental benefits in the form of reduced emissions of air pollutants and GHGs
associated with energy production and use. DOE conducts an emissions analysis to
estimate how potential standards may affect these emissions, as discussed in section IV.K
of this document; the estimated emissions impacts are reported in section V.B.6 of this
document. DOE also estimates the economic value of emissions reductions resulting
from the considered TSLs, as discussed in section IV.L of this document.
g. Other Factors
In determining whether an energy conservation standard is economically justified,
DOE may consider any other factors that the Secretary deems to be relevant. (42 U.S.C.
6295(o)(2)(B)(i)(VII)) To the extent DOE identifies any relevant information regarding
50
economic justification that does not fit into the other categories described previously,
DOE could consider such information under “other factors.”
2. Rebuttable Presumption
As set forth in 42 U.S.C. 6295(o)(2)(B)(iii), EPCA creates a rebuttable
presumption that an energy conservation standard is economically justified if the
additional cost to the consumer of a product that meets the standard is less than three
times the value of the first year’s energy savings resulting from the standard, as
calculated under the applicable DOE test procedure. DOE’s LCC and PBP analyses
generate values used to calculate the effect potential amended energy conservation
standards would have on the payback period for consumers. These analyses include, but
are not limited to, the 3-year payback period contemplated under the rebuttable
presumption test. In addition, DOE routinely conducts an economic analysis that
considers the full range of impacts to consumers, manufacturers, the Nation, and the
environment, as required under 42 U.S.C. 6295(o)(2)(B)(i). The results of this analysis
serve as the basis for DOE’s evaluation of the economic justification for a potential
standard level (thereby supporting or rebutting the results of any preliminary
determination of economic justification). The rebuttable presumption payback
calculation is discussed in section IV.F of this document.
IV. Methodology and Discussion of Related Comments
This section addresses the analyses DOE has performed for this rulemaking
regarding consumer clothes dryers. Separate subsections address each component of
51
DOE’s analyses, including relevant comments DOE received during its separate
rulemaking to amend the energy conservation standards for consumer clothes dryers prior
to receiving the Joint Agreement.
DOE used several analytical tools to estimate the impact of the standards
considered in this document. The first tool is a spreadsheet that calculates the LCC
savings and PBP of potential amended or new energy conservation standards. The
national impacts analysis uses a second spreadsheet set that provides shipments
projections and calculates national energy savings and net present value of total consumer
costs and savings expected to result from potential energy conservation standards. DOE
uses the third spreadsheet tool, the Government Regulatory Impact Model (“GRIM”), to
assess manufacturer impacts of potential standards. These three spreadsheet tools are
available on the DOE website for this rulemaking: www.regulations.gov/docket/EERE-
2014-BT-STD-0058. Additionally, DOE used output from the latest version of the
Energy Information Administration’s (“EIA’s”) Annual Energy Outlook 2023
(“AEO2023”) for the emissions and utility impact analyses.
A. Market and Technology Assessment
DOE develops information in the market and technology assessment that provides
an overall picture of the market for the products concerned, including the purpose of the
products, the industry structure, manufacturers, market characteristics, and technologies
used in the products. This activity includes both quantitative and qualitative assessments,
based primarily on publicly available information. The subjects addressed in the market
and technology assessment for this rulemaking include (1) a determination of the scope
52
of the rulemaking and product classes, (2) manufacturers and industry structure, (3)
existing efficiency programs, (4) shipments information, (5) market and industry trends,
and (6) technologies or design options that could improve the energy efficiency of
consumer clothes dryers. The key findings of DOE’s market assessment are summarized
in the following sections. See chapter 3 of the direct final rule TSD for further discussion
of the market and technology assessment.
1. Product Classes
The Joint Agreement specifies seven product classes for consumer clothes dryers.
(Joint Agreement, No. 55 at p. 9). In this direct final rule, DOE is adopting the product
classes from the Joint Agreement, as listed in Table IV.1.
Table IV.1 Joint Agreement Consumer Clothes Dryer Product Classes
Product Classes
1. Electric, Standard (4.4 ft3 or greater capacity)
2. Electric, Compact (120V) (less than 4.4 ft3 capacity)
3. Vented Electric, Compact (240V) (less than 4.4 ft3 capacity)
4. Vented Gas, Standard (4.4 ft3 or greater capacity)
5. Vented Gas, Compact (less than 4.4 ft3 capacity)
6. Ventless Electric, Compact (240V) (less than 4.4 ft3 capacity)
7. Ventless Electric, Combination Washer-Dryer
DOE further notes that product classes established through EPCA’s direct final
rule authority are not subject to the criteria specified at 42 U.S.C. 6295(q)(1) for
establishing product classes. However, in accordance with 42 U.S.C. 6295(o)(4)—which
is applicable to direct final rules—DOE has concluded that the standards adopted in this
direct final rule will not result in the unavailability in any covered product type (or class)
53
of performance characteristics, features, sizes, capacities, and volumes that are
substantially the same as those generally available in the United States currently.
35
Additionally, DOE notes that DOE’s findings in this regard are discussed in detail in
section V.B.4 of this document.
2. Technology Options
In this direct final rule, DOE considered the technology options listed in Table
IV.2, consistent with the table of technology options presented in the August 2022
NOPR. 87 FR 51734. Chapter 3 of the TSD for this direct final rule includes a detailed
list and descriptions of all technology options identified for consumer clothes dryers. As
discussed in chapter 3 of the TSD for this direct final rule, DOE has performed market
research and evaluated available consumer clothes dryers to assess existing technology
options to improve efficiency. The results of this research are discussed in chapter 3 of
the TSD for this direct final rule. DOE notes that it did not receive any comments
regarding the technology options analyzed in the August 2022 NOPR.

EPCA specifies that DOE may not prescribe an amended or new standard if the Secretary finds (and
publishes such finding) that interested persons have established by a preponderance of the evidence that the
standard is likely to result in the unavailability in the United States in any covered product type (or class) of
performance characteristics (including reliability), features, sizes, capacities, and volumes that are
substantially the same as those generally available in the United States at the time of the Secretary’s
finding. (42 U.S.C. 6295(o)(4))

B. Screening Analysis
DOE uses the following screening criteria to determine which technology options
are suitable for further consideration in an energy conservation standards rulemaking:
(1) Technological feasibility. Technologies that are not incorporated in
commercial products or in commercially viable, existing prototypes will not
be considered further.
(2) Practicability to manufacture, install, and service. If it is determined that
mass production of a technology in commercial products and reliable
installation and servicing of the technology could not be achieved on the scale
necessary to serve the relevant market at the time of the projected compliance
date of the standard, then that technology will not be considered further.
55
(3) Impacts on product utility. If a technology is determined to have a significant
adverse impact on the utility of the product to subgroups of consumers or
result in the unavailability of any covered product type with performance
characteristics (including reliability), features, sizes, capacities, and volumes
that are substantially the same as products generally available in the United
States at the time, it will not be considered further.
(4) Safety of technologies. If it is determined that a technology would have
significant adverse impacts on health or safety, it will not be considered
further.
(5) Unique-pathway proprietary technologies. If a technology has proprietary
protection and represents a unique pathway to achieving a given efficiency
level, it will not be considered further, due to the potential for monopolistic
concerns.
10 CFR part 430, subpart C, appendix A, sections 6(b)(3) and 7(b).
In sum, if DOE determines that a technology, or a combination of technologies,
fails to meet one or more of the listed five criteria, it will be excluded from further
consideration in the engineering analysis. The reasons for eliminating any technology are
discussed in the following sections.
The subsequent sections include DOE’s evaluation of each technology option
against the screening analysis criteria, and whether DOE determined that a technology
option should be excluded (“screened out”) based on the screening criteria.
56
1. Screened Out Technologies
In conducting the screening analysis for this direct final rule, DOE considered
comments it had received in response to the screening analysis conducted for the August
2022 NOPR.
a. Thermoelectric heating, electric only
DOE notes that thermoelectric heating clothes dryers are still undergoing
preliminary research, including at Oak Ridge National Laboratory (“ORNL”). While
ORNL’s test results of a preliminary prototype have shown the potential for improved
efficiency, ORNL indicated that the initial prototype design produced longer-than-desired
drying times due to direct-contact heat transfer limitations via the drum surface. ORNL
subsequently developed another prototype that added pumped secondary water loops that
transferred heat from the thermoelectric modules to the process air via air-to-water heat
exchangers to further improve efficiency and minimize cycle length. ORNL’s testing
indicated efficiency and cycle times for this prototype that are approximately equivalent
to those of vapor compression heat pump clothes dryers.
36
Because the research for such
a thermoelectric heating clothes dryer that produces energy savings and meets consumer
expectations for drying cycle time is still in the prototype stage, DOE determined that this
technology option would not be practicable to manufacture, install, and service on a scale
necessary to serve the relevant market at the time of the projected compliance date of any

57
new or amended consumer clothes dryer standards, and did not consider it for further
analysis.
b. Microwave, electric only
Due to the large energy savings associated with microwave drying, this
technology was the subject of a multiyear development effort at the Electric Power
Research Institute (“EPRI”) in the mid-1990s.
37
At least one major manufacturer
Whirlpool—developed a countertop-scale version of such a product as recently as 2002,
38
but to date this technology has not been successfully commercialized.
Microwave drying introduces significant technical and safety issues with potential
arcing from metallic objects in the fabric load, including zippers, buttons, or “stray” items
such as coins. While efforts have been made to mitigate the conditions that are favorable
to arcing or to detect incipient arcing and terminate the cycle, the possibility of fabric
damage cannot be completely eliminated.
39
In addition to those consumer utility impacts,
these conditions can also pose a safety hazard. For these reasons, microwave drying was
not considered further for analysis.
c. Indirect heating
Indirect heating would be viable only in residences that use a hydronic heating
system. Also, in order to derive clothes dryer heat energy from a home’s heating system,

58
significant plumbing work would be required to circulate heated water through a heat
exchanger in the clothes dryer. Therefore, this technology option does not meet the
criterion of practicability to install on a scale necessary to serve the relevant market at the
time of the effective date of any new standard and was not considered for further
analysis.
d. RF drying, electric only
CoolDry, LLC (“CoolDry”) developed an RF clothes dryer prototype, claiming an
efficiency of 90 percent, compared to 50 percent for conventional clothes dryers.
40
CoolDry stated that its RF drying technology operates at lower temperatures than do
conventional clothes dryers and, because the transfer of energy to clothes is not
dependent on convective heat transfer, the RF clothes dryer requires less tumbling and
subsequently consumes less energy for drum rotation than a conventional clothes dryer.
Because this technology was in the prototype stage at the time it was initially considered
and the company is no longer in business, research and development is unlikely to be
ongoing. Therefore, DOE determined that this technology option would not be
practicable to manufacture, install, and service on a scale necessary to serve the relevant
market at the time of the projected compliance date of any new or amended consumer
clothes dryer standards and did not consider it for further analysis.
40
Cool Dry did not specify the metric or test method used to determine the efficiency of its prototype.
59
e. Ultrasonic drying, electric only
Researchers at ORNL have developed an ultrasonic drying prototype that uses
piezoelectric transducers to separate water from clothes through water cavitation
produced by ultrasonic vibrations. According to their research, the energy imparted to the
water must overcome surface tension in order to break the water into droplets, but this
energy is substantially less than the latent heat of vaporization of water, which is the
primary thermodynamic barrier for conventional evaporation drying. The ORNL
researchers anticipate that ultrasonic drying technology will result in an energy factor
41
of
greater than 10 and a drying time of less than 20 minutes.
42
Because this technology is
still in the prototype stage, however, DOE determined that this technology option would
not be practicable to manufacture, install, and service on a scale necessary to serve the
relevant market at the time of the projected compliance date of any new or amended
consumer clothes dryer standards and did not consider it for further analysis.
DOE did not receive any comments in response to the August 2022 NOPR
regarding these screened out technology options, and for the reasons discussed, screened
out the same technologies for this direct final rule analysis.
2. Remaining Technologies
Through a review of each technology, DOE tentatively concludes that all of the
other identified technologies listed in section IV.A.2 of this document met all screening
41
This energy factor incorporates only active mode energy use and not standby mode and off mode energy
use.

60
criteria to be examined further as design options in DOE’s direct final rule analysis. In
summary, DOE did not screen out the following technology options:
Table IV.3 Retained Design Options for Consumer Clothes Dryers
Dryer Control or Drum Upgrades
Improved termination
Modified operating conditions
Improved air circulation
Increased insulation
Improved drum design
Methods of Exhaust Heat Recovery (vented models only)

Transformerless Power Supply with Auto-Powerdown
DOE determined that these technology options are technologically feasible
because they are being used or have previously been used in commercially available
products or working prototypes. DOE also finds that all of the remaining technology
options meet the other screening criteria (i.e., practicable to manufacture, install, and
service and do not result in adverse impacts on consumer utility, product availability,
health, or safety). For additional details, see chapter 4 of the direct final rule TSD.
As previously discussed, on February 14, 2024, DOE received a second joint
statement from the same group of stakeholders that submitted the Joint Agreement in
61
which the signatories reaffirmed the standards recommended in the Joint Agreement.
43
In
particular, the letter states that the joint stakeholders do not anticipate the recommended
standards will negatively affect features or performance.
C. Engineering Analysis
The purpose of the engineering analysis is to establish the relationship between
the efficiency and cost of consumer clothes dryers. There are two elements to consider in
the engineering analysis: the selection of efficiency levels to analyze (i.e., the efficiency
analysis) and the determination of product cost at each efficiency level (i.e., the cost
analysis). In determining the performance of higher efficiency products, DOE considers
technologies and design option combinations not eliminated by the screening analysis.
For each product class, DOE estimates the baseline cost, as well as the incremental cost
for the product/equipment at efficiency levels above the baseline. The output of the
engineering analysis is a set of cost-efficiency “curves” that are used in downstream
analyses (i.e., the LCC and PBP analyses and the NIA).
1. Efficiency Analysis
DOE typically uses one of two approaches to develop energy efficiency levels for
the engineering analysis: (1) relying on observed efficiency levels in the market (i.e., the
efficiency-level approach), or (2) determining the incremental efficiency improvements
associated with incorporating specific design options to a baseline model (i.e., the design-
option approach). Using the efficiency-level approach, the efficiency levels established
43
This document is available in the docket at: www.regulations.gov/comment/EERE-2014-BT-STD-0058-
0058.
62
for the analysis are determined based on the market distribution of existing products (in
other words, based on the range of efficiencies and efficiency-level “clusters” that
already exist on the market). Using the design-option approach, the efficiency levels
established for the analysis are determined through detailed engineering calculations
and/or computer simulations of the efficiency improvements from implementing specific
design options that have been identified in the technology assessment. DOE may also
rely on a combination of these two approaches. For example, the efficiency-level
approach (based on actual products on the market) may be extended using the design-
option approach to interpolate to define “gap fill” levels (to bridge large gaps between
other identified efficiency levels) and/or to extrapolate to the “max-tech” level
(particularly in cases where the “max-tech” level exceeds the maximum efficiency level
currently available on the market).
For this direct final rule, DOE used an efficiency-level approach, supplemented
with reverse engineering. This approach involved first testing and then physically
disassembling a representative sample of commercially available products, reviewing
publicly available cost information, and modeling equipment cost. From this information
and through the reverse engineering process, DOE estimated the manufacturer production
costs (“MPCs”) for a range of products currently available on the market, considering the
design options and the steps manufacturers would likely take to reach a certain efficiency
level. As part of this analysis, DOE included test units that represent baseline models,
newly introduced units on the market, units with unique configurations, and units with
technologies as observed in the technology assessment. The efficiency levels analyzed as
63
part of this engineering analysis are attainable using commercially available clothes dryer
technologies, or technologies that have been demonstrated in working prototypes.
a. Baseline Efficiency Levels
For each product/equipment class, DOE generally selects a baseline model as a
reference point for each class, and measures changes resulting from potential energy
conservation standards against the baseline. The baseline model in each
product/equipment class represents the characteristics of a product/equipment typical of
that class (e.g., capacity, physical size). Generally, a baseline model is one that just
meets current energy conservation standards, or, if no standards are in place, the baseline
is typically the most common or least efficient unit on the market.
The baseline clothes dryer efficiency levels for this direct final rule differ from
the existing energy conservation standards that were established in the 2011 rulemaking
analysis primarily due to the difference between the then-current appendix D1, which
DOE used to evaluate products in the previous rulemaking, and the present version of
appendix D2, established in the October 2021 TP Final Rule and which DOE used as the
basis for this analysis. Appendix D2 includes test methods that more accurately measure
the effects of automatic cycle termination and that may result in differences in the total
measured energy consumption of the test cycle as compared to the test methods in
appendix D1. Specifically, for automatic termination control dryers, appendix D2
requires a lower FMC of the test load and does not rely on a field use factor to account
for the over-drying energy consumption, instead requiring that the automatic termination
drying program run to the end of the cycle. Additionally, appendix D2 contains
64
instructions for the testing of timer dryers, which include a lower FMC of the test load as
compared to the version of appendix D1 used for the 2011 rulemaking analysis.
For the engineering analysis, DOE began by identifying the efficiency level
corresponding to the Federal minimum energy conservation standards for each product
class. Due to the test procedure changes adopted in the October 2021 Final Rule, DOE
determined the baseline efficiency level representative of minimally compliant products
when tested under appendix D2. To identify the appendix D2 baseline levels, DOE tested
22 models that were certified as minimally compliant with the current energy
conservation standards, from across all product classes. Because certified performance
data are not available for models on the market tested in accordance with both appendix
D1 and appendix D2, DOE tested each basic model in its test sample in accordance with
appendix D1 and appendix D2 and used the test values for appendix D2 to determine the
baseline models in support of this engineering analysis. Due to the differences in the two
test procedures previously described, the baseline CEF
D2
measured using appendix D2 is
numerically lower for each product class than the corresponding CEF
D1
value in the
current energy conservation standards, though that does not indicate a lower efficiency.
The test procedure differences drive the lower baseline CEF
D2
values and do not
represent a lower efficiency or backsliding.
With regard to the vented gas compact product class, DOE is unaware of any
currently available commercial products that fall within the vented gas compact product
class. To determine the baseline level for this product class, DOE analyzed a vented gas
compact-size model that was previously available on the market prior to the effective
65
date of the current energy conservation. DOE’s previous testing of that model—which
utilized electromechanical controls—suggests that the model would not be compliant
with the existing standards. DOE expects that manufacturers would implement electronic
controls as a design option to produce vented gas compact clothes dryers that minimally
comply with the existing standard. DOE determined the efficiency performance that
would be achieved through the addition of electronic controls by applying the same
relative efficiency improvement observed with the implementation of electronic controls
for standard-size vented gas clothes dryers, as shown in Table IV.8 in section IV.C.1.b of
this document. The resulting estimated level of baseline performance for the vented gas
compact product class is consistent with the efficiency level recommended by the Joint
Agreement for this product class.
The baseline efficiency levels considered for this analysis are presented along
with the current standards in Table IV.4 and are discussed in more detail in chapter 5 of
the direct final rule TSD. The baseline values are the same as those proposed in the
August 2022 NOPR, except for the vented gas compact product class as discussed.

As discussed, the baseline CEF
D2
values represent differences in test procedure between appendix D1 and
appendix D2 and do not constitute backsliding. CEF
D2
baseline efficiency levels as measured under
appendix D2 account for differences in the effectiveness of automatic cycle termination. Manufacturers
66
implement automatic termination in a variety of ways, which will impact the representations as measured
under appendix D2 and result in a range of possible CEF
D2
values, as compared to the CEF
D1
values in the
existing Federal standards.
b. Incremental Efficiency Levels
DOE developed incremental efficiency levels by reviewing products currently
available on the market and by testing and reverse engineering products in the DOE test
sample in support of the direct final rule. For each product class, DOE analyzed several
efficiency levels and determined the incremental MPC at each of these levels. DOE
initially reviewed data in DOE’s Compliance Certification Database (“CCD”) to evaluate
the range of efficiencies for consumer clothes dryers currently available on the market.
As discussed in chapter 5 of the direct final rule TSD, non-ENERGY STAR-qualified
products (i.e., generally units with lower-rated efficiencies) are typically tested using
appendix D1, while ENERGY STAR-qualified products are required to be tested using
appendix D2. As a result, DOE conducted testing on a representative sample of non-
ENERGY STAR-qualified products using appendix D2 to determine appropriate initial
incremental efficiency levels for each product class. DOE observed that while electronic
controls are typically implemented with other design options in this analysis, the
improved automatic termination precision offered by switching to electronic controls
contributed significantly to an increase in efficiency. This efficiency gain informed the
first incremental efficiency levels for most product classes and was noted simply as
electronic controls in the design options listed in the tables later in this section. The
design options associated with higher efficiency levels were subsequently distinguished
according to specific design options DOE found manufacturers used to meet these higher
efficiencies. As part of DOE’s analysis, the maximum available efficiency level is the
67
highest efficiency unit currently available on the market. DOE also defines a “max-tech”
efficiency level to represent the maximum possible efficiency for a given product.
For the vented gas compact product class, no units were available on the market at
the time of the analysis whose rated value exceeded the baseline level. Given recent
market trends, DOE does not have reason to expect manufacturers to re-introduce
compact-size vented gas clothes dryers to the market, regardless of amendments to
energy conservation standards. Accordingly, DOE did not consider any higher efficiency
levels for this product class.
In defining the incremental efficiency levels for the other product classes for this
direct final rule, DOE considered comments it had received in response to the
incremental efficiency levels proposed in the August 2022 NOPR, including several from
commenters who support the Joint Agreement.
The CA IOUs supported DOE's decision to adopt the updated max-tech levels as
indicative of the growth and maturity of heat pump technologies for vented and ventless
products. The CA IOUs further commented that adopting the max-tech levels sets a key
precedent for subsequent DOE energy efficiency and non-DOE rulemakings to represent
the true potential of a product class. (California IOUs, No. 50 at pp. 4–5)
AHAM and Whirlpool disagreed with DOE's tentative determination that the
proposed standards in the August 2022 NOPR would allow for electromechanical
controls. AHAM and Whirlpool commented that electronic controls are required to
68
enable the technology options for the proposed TSL. Whirlpool further commented that
electromechanical control dryers are not sophisticated enough to enable the other
technology options that DOE described in the August 2022 NOPR analysis and therefore
could not be used effectively with the appendix D2 test procedure. Whirlpool stated that
DOE's NOPR analysis missed several key aspects where utility and performance could be
lessened in order to meet the proposed standard levels. Whirlpool noted that the average
CEF score of the five tested units in the vented electric standard product class with
electromechanical controls in the August 2022 NOPR analysis is 2.64 lb/kWh, over 30-
percent lower than the proposed standard. AHAM stated that electromechanical controls
have consumer utility in that they are easy to use and reduce the overall costs associated
with the product, and that requiring electronic controls would result in investment costs
for manufacturers and increased purchase prices for consumers. AHAM requested that
DOE retain electromechanical controls among a consumer's purchase options as,
according to AHAM, they are a desirable feature for reliability, they provide reduced
appliance cost among consumers, and their elimination from the market would likely
cause consumers to postpone the purchase of new dryers, in turn increasing the total
national energy consumption. Whirlpool stated concern regarding a forced regulatory
phaseout of electromechanical controls because they are incorporated in a popular and
affordable segment of consumer clothes dryers, and noted that although some electronic
controls could be “hidden” from the consumer, there could be some lost utility from the
easy and low-cost repairability of electromechanical control dryers. (AHAM, No. 46 at
pp. 5, 10; Whirlpool, No. 53 at pp. 3–4)
69
DOE is not aware of reliability issues associated with the implementation of
electronic controls relative to electromechanical controls. However, DOE acknowledges
that a transition from electromechanical controls to electronic controls may require
manufacturer investment costs to redesign products and would likely increase purchase
price for consumers, as captured in the incremental costs estimated and presented in this
direct final rule analysis. Based on its analysis for this direct final rule, DOE believes
that component costs associated with the implementation of electronic controls are lower
than those estimated in the August 2022 NOPR analysis, which is reflected in the updated
MPCs for the efficiency levels that entail a shift to electronic controls. These costs are
reflected in the MPCs, which are the basis for the LCC and PBP analyses, in which
consumer impacts related to increased purchase price and repair and maintenance costs
are considered. Additionally, DOE reevaluated repair costs and accordingly implemented
higher repair costs associated with electronic controls in this direct final rule analysis,
consistent with Whirlpool’s comments. See section IV.F of this document and chapter 8
of the direct final rule TSD for additional details.
Regarding the concern that clothes dryers equipped with electromechanical
controls could not be tested under appendix D2, DOE notes that its test sample shows that
requiring the use of the appendix D2 test procedure will not preclude the use of
electromechanical controls. As discussed in chapter 5 of the direct final rule TSD, DOE
tested baseline models with electromechanical controls under appendix D2, where
available. For the ventless electric compact (240V) product class and the ventless electric
combination washer-dryer product class, there were no baseline models identified with
electromechanical controls; however, the same efficiency-level approach was taken to
70
establish the efficiency-level structures for these product classes. The baseline efficiency
levels in this direct final rule represent a minimally compliant, basic-construction
consumer clothes dryer on the market, such as a dryer with electromechanical controls,
and were set according to the lowest tested values under appendix D2 in each product
class. As Whirlpool noted, the average CEF score of the five tested units in the vented
electric standard product class with electromechanical controls was significantly lower
than the proposed standard, further indicating the efficiency savings associated with a
transition to a combination of electronic controls and higher design options. Regarding
the concern that the proposed amended standards would require the implementation of
electronic controls, DOE reiterates that although it expects that electronic controls are
most likely to be used to achieve higher efficiency levels, and a review of ENERGY
STAR-qualified products suggests increased prevalent use of electronic controls,
manufacturers are not required to implement these specific design options to meet
amended standards. DOE therefore does not expect the amended standards to preclude
electromechanical controls should manufacturers choose to implement them.
Regarding AHAM and Whirlpool’s comments that the required implementation
of electronic controls to reach efficiency levels above the existing standard may result in
a loss of consumer utility associated with the traditional user interface utilizing
electromechanical controls, DOE’s testing and analysis of models currently on the market
confirms Whirlpool’s statement that electronic controls may be “hidden” from consumers
who prefer a more traditional user interface. This may be accomplished by implementing
physical dials for consumer use that in turn manipulate the electronic controls in order to
achieve the efficiency savings associated with electronic controls while providing the
71
user experience of electromechanical controls. Therefore, even if electronic controls are
utilized, DOE does not expect a loss in consumer utility associated with the use of
electromechanical controls. DOE notes that AHAM recommended the proposed
efficiency levels in the Joint Agreement on behalf of its members, including Whirlpool,
in the Joint Agreement, which includes efficiency levels that can be achieved with the
implementation of electronic controls.
Whirlpool stated that there may be greater visibility and scrutiny of drying times
associated with electronic control clothes dryers among consumers, as electromechanical
control dryers do not display drying times. According to Whirlpool, consumers may
believe they are losing control of their dryers in a way that results in additional energy
consumption, and DOE should account for this possible behavioral shift and lost energy
savings. (Whirlpool, No. 53 at p. 7)
DOE is not aware of any data suggesting that the behavior of consumers of with
clothes dryers utilizing electronic controls results in greater energy use than for
consumers with clothes dryers utilizing electromechanical controls and notes that
electronic controls are typically more efficient than electromechanical controls. As
previously noted, manufacturers currently provide electronic controls that provide the
experience of electromechanical controls through the use of dials which would avoid any
loss in consumer utility.
GEA stated that while the appendix D2 test procedure requires use of the
“normal” or ”medium” dryness setting for the clothes dryer test cycle, most labs,
72
according to GEA, understand the “optimum” dryness setting to be the “normal” setting
for appendix D2. GEA stated that it provides further clarity to consumers and test labs in
the use and care manual for products with an “optimum” dryness setting by specifying
that optimum is the dryness setting to use for most clothes when running the “cottons”
cycle (the drying cycle recommended for certain consumer clothes dryers manufactured
by GEA for drying cotton). Therefore, based on the cycle settings provided by the
additional test information DOE published on October 13, 2022, and information
provided by Guidehouse to GEA under a non-disclosure agreement, GEA stated that
DOE incorrectly tested two models in its test sample and urged DOE to either rerun its
testing, exclude the models in question from its analysis, or accept the data provided by
GEA and adjust its savings model. (GEA, No. 49 at pp. 2–3)
DOE notes that the baseline units GEA referenced are certified under appendix
D1, and although these units were not originally intended to be tested under the appendix
D2 test procedure, DOE tested them using the appropriate cycle settings under the
appendix D2 test procedure to support the engineering analysis. These settings were
different than the “optimum” dryness setting specified in the use and care manual for
these particular units. Although GEA referred to specific cycle settings for consumer
use, DOE notes that this instruction for cycle settings does not supersede the
requirements of the appendix D2 test procedure. Additionally, DOE notes that the test
cycle settings used were within the range anticipated and not expressly warned against by
the owner’s manual or use and care manual. Therefore, DOE maintains that the correct
cycle settings were used to test the units in question.
73
Whirlpool stated that DOE should have presented the cycle times before and after
wrinkle prevention mode was enabled for models in the test sample that had wrinkle
prevention mode on by default. Whirlpool further stated that models reported in the data
had extremely long cycle times, between 88 and 319 minutes, but that such times were
distorted due to testing with wrinkle protection mode enabled. Additionally, Whirlpool
stated that testing of consumer clothes dryers with wrinkle prevention mode enabled by
default may have distorted some of the tested settings and the resulting CEF scores
because wrinkle prevention results in additional cycle time of continuous tumbling after
the heating element has been turned off. Whirlpool stated that, this results in an energy
penalty as the additional cycle time potentially allows for moisture absorption in the test
load to the point of failing to meet the required FMC of 2 percent, and therefore a retest is
required using the highest dryness level setting associated with more energy consumption
and thus a lower average measured CEF. Whirlpool further stated that wrinkle prevention
mode does not produce an accurate comparison of average cycle times and CEF scores of
these dryers compared to other dryers that do not have wrinkle prevention modes enabled
by default, and DOE should have also recorded the CEF scores, FMC, and drying times
of these models before they were allowed to enter wrinkle prevention mode. Whirlpool
stated that this data should have been used to inform comparisons between dryers and the
development of baseline efficiency levels. Whirlpool stated that if these dryers were
designed to the appendix D2 test procedure, wrinkle prevention mode would likely not
have been enabled by default. (Whirlpool, No. 53 at pp. 9–10)
In the August 2013 TP Final Rule, DOE clarified that if a clothes dryer is
equipped with a wrinkle prevention mode that is activated by default in the as-shipped
74
position, the cycle shall be considered complete after the end of the wrinkle prevention
mode. 76 FR 49607, 4962349624. Although wrinkle prevention mode may have been
disabled had the test units been designed for appendix D2 testing, DOE stated previously
that accurate testing of existing baseline units according to the appendix D2 test
procedure was essential for the analysis, including the use of optional cycle settings that
are enabled by default and that do not affect the program, temperature, or dryness
settings. The test procedure in appendix D2 therefore requires that testing include
wrinkle prevention mode if it is enabled by default. DOE maintains, as it was unable to
predict or assume the cycle settings Whirlpool would have selected had the test units
been designed for appendix D2 testing, that the test units in question were properly tested
in accordance with appendix D2 using the correct cycle settings consistent with the DOE
test procedure.
Chapter 5 of the direct final rule TSD discusses the incremental efficiency levels
for each of the product classes in this analysis. The revised CEF
D2
efficiency levels for
each product class are shown below in Table IV.5 through Table IV.10, along with the
current energy conservation standards in CEF

for comparison. As discussed in section
IV.C.1.a of this document, the baseline CEF
D2
values estimated for the preliminary
analysis are lower than the current CEF
D1
values in the energy conservation standards due
to the differences in testing between appendix D1 and appendix D2.

DOE is aware of consumer clothes dryers in the electric standard product class that perform at higher
efficiencies than the proposed max-tech level, but those models are not representative of the typical
capacity in the electric standard product class. Therefore, based on the certified performance of those
models and additional investigative testing, DOE determined a representative max-tech efficiency for the
electric standard product class that reflects an appropriate, representative unit capacity. See chapter 5 of the
final rule TSD for more information.

2. Cost Analysis
The cost analysis portion of the engineering analysis is conducted using one or a
combination of cost approaches. The selection of cost approach depends on a suite of
factors, including the availability and reliability of public information, characteristics of
the regulated product, and the availability and timeliness of purchasing the product on the
market. The cost approaches are summarized as follows:
Physical teardowns: Under this approach, DOE physically dismantles a
commercially available product, component by component, to develop a
detailed bill of materials for the product.
Catalog teardowns: In lieu of physically deconstructing a product, DOE
identifies each component using parts diagrams (available from manufacturer
websites or appliance repair websites, for example) to develop the bill of
materials for the product.
Price surveys: If neither a physical nor catalog teardown is feasible (for
example, for tightly integrated products such as fluorescent lamps, which are
78
infeasible to disassemble and for which parts diagrams are unavailable) or
cost-prohibitive and otherwise impractical (e.g., large commercial boilers),
DOE conducts price surveys using publicly available pricing data published
on major online retailer websites and/or by soliciting prices from distributors
and other commercial channels.
In the present case, DOE conducted the analysis using physical product teardowns
to determine the baseline MPC for each product class as outlined in chapter 5 of the
direct final rule TSD. DOE developed the cost-efficiency relationships for each product
class as discussed in section IV.C.3 of this document. DOE developed incremental
MPCs based on product teardowns and manufacturing cost modeling of the expected
design changes at each efficiency level. DOE observed that the basic product designs of
vented electric and vented gas clothes dryers are similar except for the heating system.
DOE also observed that the technology designs of standard-size and compact-size
consumer clothes dryers are similar as well, simply scaled in size. As a result, in the
absence of models available on the market at certain efficiency levels for certain product
classes, DOE estimated the incremental MPC for these based on the same design changes
observed for the electric standard product class. DOE updated the cost-efficiency
analysis from the preliminary analysis by updating the costs of raw materials and
purchased components, as well as updating costs for manufacturing equipment, labor, and
depreciation. DOE also used information from the teardown of units in the updated test
sample to inform updates to the cost-efficiency analysis. Not all units in the updated test
sample were torn down; DOE focused on units recently introduced in the market, units
with unique configuration, and units with technologies that were not available at the time
79
of the preliminary analysis to better inform the costs associated with particular product
classes and design options.
The resulting bill of materials provides the basis for the MPC estimates in this
direct final rule. The baseline MPCs for each consumer clothes dryer product class are
listed in Table IV.11, with all costs presented in 2022 dollars.

To account for manufacturers’ non-production costs and profit margin, DOE
applies a multiplier (the manufacturer markup) to the MPC. The resulting manufacturer
selling price (“MSP”) is the price at which the manufacturer distributes a unit into
commerce. DOE developed an average manufacturer markup by examining the annual
Securities and Exchange Commission (“SEC”) 10-K reports filed by publicly traded
manufacturers primarily engaged in appliance manufacturing and whose combined
product range includes consumer clothes dryers.

3. Cost-Efficiency Results
The results of the engineering analysis are presented as cost-efficiency data for
each of the efficiency levels for each of the product classes that were analyzed, as well as
those extrapolated from a product class with similar features. DOE developed estimates
of MPCs for each unit in the teardown sample to develop a comprehensive set of
incremental MPCs (i.e., the additional costs manufacturers would likely incur by
producing consumer clothes dryers at each efficiency level compared to the baseline).
The resulting incremental MPCs from this analysis are provided in Table IV.12
through Table IV.17. See chapter 5 of the direct final rule TSD for additional detail on

The markups analysis D. Markups Analysis
develops appropriate markups (e.g., manufacturer markups, retailer markups,
distributor markups, contractor markups) in the distribution chain and sales taxes to
convert the MSP estimates derived in the engineering analysis to consumer prices, which
are then used in the LCC and PBP analysis. At each step in the distribution channel,
companies mark up the price of the product to cover business costs and profit margin.
DOE considered two distribution channels through which consumer clothes
dryers move from manufacturers to consumers. The majority of consumer clothes dryer
sales go through the direct retailer channel, in which manufacturers sell the products
directly to retailers, who then sell to consumers. This direct retailer channel accounts for
90 percent of the consumer clothes dryer market. The rest of the market goes through a
separate new construction distribution channel, in which manufacturers sell the products
to wholesalers, who in turn sell the products to general contractors, then to consumers.
83
The main parties in the post-manufacturer distribution channels are retailers, wholesalers,
and contractors.
DOE developed baseline and incremental markups for each actor in the
distribution channels. Baseline markups are applied to the price of products with baseline
efficiency, while incremental markups are applied to the difference in price between
baseline and higher efficiency models (the incremental cost increase). The incremental
markup is typically less than the baseline markup and is designed to maintain similar per-
unit operating profit before and after new or amended standards.
47
DOE relied on economic data from the U.S. Census Bureau to estimate average
baseline and incremental markups. Specifically, DOE used the 2017 Annual Retail Trade
Survey for the “electronics and appliance stores” sector to develop retailer markups;
48
the
2017 Annual Wholesale Trade Survey for “household appliances, and electrical and
electronic goods merchant wholesalers” to estimate wholesaler markups;
49
and the 2017
Economic Census for the residential construction sector to derive general contractor
markups.
50
47
Because the projected price of standards-compliant products is typically higher than the price of baseline
products, using the same markup for the incremental cost and the baseline cost would result in higher per-
unit operating profit. While such an outcome is possible, DOE maintains that in markets that are
reasonably competitive it is unlikely that standards would lead to a sustainable increase in profitability in
the long run.

E. Energy Use Analysis
The purpose of the energy use analysis is to determine the annual energy
consumption of consumer clothes dryers at different efficiencies in representative U.S.
single-family homes, multifamily residences, and mobile homes and to assess the energy
savings potential of increased consumer clothes dryer efficiency. The energy use
analysis estimates the range of energy use of consumer clothes dryers in the field (i.e., as
they are actually used by consumers). The energy use analysis provides the basis for
other analyses DOE performed, particularly assessments of the energy savings and the
savings in consumer operating costs that could result from adoption of amended or new
standards.
In conducting the energy use analysis for this direct final rule, DOE considered
comments it had received in response to the proposed analysis in the August 2022 NOPR.
DOE received a comment from AHAM regarding the number of annual use cycles in the
August 2022 NOPR energy use analysis. AHAM requested that DOE review the 2020
Residential Energy Consumption Survey (“2020 RECS”) data
51
and adjust the annual
number of cycles accordingly. AHAM stated that it previously commented that RECS
2015 suggested an annual number of cycles of 236 as opposed to the 283 cycles in the

85
current test procedure, which is consistent with the observation that clothes washer cycles
have decreased in number to 234 cycles per year using the 2015 RECS. According to
AHAM, it does not make sense for clothes washer cycles to decrease and clothes dryer
cycles to increase or even stay the same. AHAM suggested that based on the 2020
RECS, the annual number of cycles should be 209. (AHAM, No. 46 at p. 12)
In the August 2022 NOPR analysis, DOE used data from the EIA’s 2015
Residential Energy Consumption Survey (“2015 RECS”) to establish a reasonable range
of energy consumption in the field for consumer clothes dryers. DOE noted that the
microdata for the 2020 RECS was not available at the time the NOPR analysis was
conducted but stated that it would update the underlying data to 2020 RECS if it was
available prior to the final rule. 87 FR 51762. DOE is aware that the 2020 RECS has
been published.
52
This survey collected data from 18,496 housing units and was designed
by EIA to represent the household population in the United States. Therefore, DOE has
integrated this data into its analysis for the direct final rule concerning households using
clothes dryers.
DOE divided the sample of households into four subsamples for the product
classes being analyzed: standard or compact consumer clothes dryers using electricity or
natural gas as the dryer fuel. For compact consumer clothes dryers, DOE developed a
52
U.S. Department of Energy Energy Information Administration, Residential Energy
Consumption Survey: 2020 Public Use Data Files. Available at
www.eia.gov/consumption/residential/data/2020/index.php?view=microdata (last accessed April 21, 2023).
86
subsample consisting of households with an electric or gas clothes dryer in multifamily
buildings, manufactured homes, and single-family homes with less than 1,000 square feet
and no garage or basement, since these products are most likely to be found in these
housing types.
The energy use analysis requires DOE to establish a range of total annual usage
(number of cycles) in order to estimate annual energy consumption by a clothes dryer.
DOE estimated the number of clothes dryer cycles per year for each sample household
using data from the 2020 RECS on the number of laundry loads washed (clothes washer
cycles) per week and the frequency of clothes dryer use. The average annual energy
consumption was then calculated, reflecting an average annual sample-weighted usage of
213 cycles per year.
For each considered efficiency level, DOE derived the field energy use by
separately estimating the active mode and standby mode energy use and then adding
them together. The per-cycle active mode energy consumption was estimated using the
DOE clothes dryer test procedure at appendix D2. It was then back calculated from the
test procedure results by dividing the weight (lb) of clothes dried per-cycle (i.e., 8.45 lb
for standard and 3 lb for compact consumer clothes dryers) by the CEF
D2
(lb/kWh) and
subtracting standby power. DOE adjusted the test procedure energy use to reflect field
conditions by making an adjustment for clothes dryer load weight and moisture removal
factor. Chapter 7 of the direct final rule TSD provides more detail about these
calculations.
87
DOE also considered the impact of clothes dryer operation on home heating and
cooling loads, given that a clothes dryer releases heat to the surrounding environment. If
the clothes dryer is located indoors, its use will tend to slightly reduce the heating load
during the heating season and slightly increase the cooling load during the cooling
season. To calculate this impact, DOE first estimated whether the clothes dryer in a
RECS sample home is located in conditioned space (referred to as “indoors”) or in
unconditioned space (e.g., garages, unconditioned basements, outdoor utility closets, or
attics). Based on the 2020 RECS and the 2019 American Housing Survey (“AHS”),
53
DOE assumed that 50 percent of vented standard electric and gas consumer clothes
dryers are located indoors, while 100 percent of compact and ventless consumer clothes
dryers are located indoors. For these installations, DOE used the results from a European
Union study about the impacts of consumer clothes dryers on home heating and cooling
loads to determine the appropriate factor to apply to the total clothes dryer energy use.
54
This study reported that for vented consumer clothes dryers, there is a factor of negative 3
to 9 percent (average 3 percent), and for ventless consumer clothes dryers there is a factor
of positive 7 to 15 percent (average 11 percent).

For units that are located in conditioned space, a negative factor for vented consumer clothes dryers
translates to a penalty in energy use, whereas a positive factor for ventless consumer clothes dryers
translates to a credit in energy use. For details of the calculations, see the Rüdenauer and Gensch study

88
approximately the same for all of the considered efficiency levels because the amount of
air passing through the clothes dryer does not vary.
Chapter 7 of the direct final rule TSD provides details on DOE’s energy use
analysis for consumer clothes dryers.
F. Life-Cycle Cost and Payback Period Analysis
DOE conducted LCC and PBP analyses to evaluate the economic impacts on
individual consumers of potential energy conservation standards for consumer clothes
dryers. The effect of new or amended energy conservation standards on individual
consumers usually involves a reduction in operating cost and an increase in purchase
cost. DOE used the following two metrics to measure consumer impacts:
The LCC is the total consumer expense of an appliance or product over the life
of that product, consisting of total installed cost (manufacturer selling price,
distribution chain markups, sales tax, and installation costs) plus operating
costs (expenses for energy use, maintenance, and repair). To compute the
operating costs, DOE discounts future operating costs to the time of purchase
and sums them over the lifetime of the product.
The PBP is the estimated amount of time (in years) it takes consumers to
recover the increased purchase cost (including installation) of a more efficient
product through lower operating costs. DOE calculates the PBP by dividing
the change in purchase cost at higher efficiency levels by the change in annual
89
operating cost for the year that amended or new standards are assumed to take
effect.
For any given efficiency level, DOE measures the change in LCC relative to the
LCC in the no-new-standards case, which reflects the estimated efficiency distribution of
consumer clothes dryers in the absence of new or amended energy conservation
standards. In contrast, the PBP for a given efficiency level is measured relative to the
baseline product.
For each considered efficiency level in each product class, DOE calculated the
LCC and PBP for a nationally representative set of housing units. As stated previously,
DOE developed household samples from the 2020 RECS. For each sample household,
DOE determined the energy consumption for the consumer clothes dryers and the
appropriate energy price. By developing a representative sample of households, the
analysis captured the variability in energy consumption and energy prices associated with
the use of consumer clothes dryers.
Inputs to the calculation of total installed cost include the cost of the product
which includes MPCs, manufacturer markups, retailer and distributor markups, and sales
taxesand installation costs. Inputs to the calculation of operating expenses include
annual energy consumption, energy prices and price projections, repair and maintenance
costs, product lifetimes, and discount rates. DOE created distributions of values for
product lifetime, discount rates, and sales taxes, with probabilities attached to each value,
to account for their uncertainty and variability.
90
The computer model DOE uses to calculate the LCC relies on a Monte Carlo
simulation to incorporate uncertainty and variability into the analysis. The Monte Carlo
simulations randomly sample input values from the probability distributions and
consumer clothes dryer user samples. For this rulemaking, the Monte Carlo approach is
implemented in MS Excel together with the Crystal Ball
TM
add-on.
56
The model
calculated the LCC for products at each efficiency level for 10,000 housing units per
simulation run. The analytical results include a distribution of 10,000 data points
showing the range of LCC savings for a given efficiency level relative to the no-new-
standards case efficiency distribution. In performing an iteration of the Monte Carlo
simulation for a given consumer, product efficiency is chosen based on its probability. If
the chosen product efficiency is greater than or equal to the efficiency of the standard
level under consideration, the LCC calculation reveals that a consumer is not impacted by
the standard level. By accounting for consumers who already purchase more efficient
products, DOE avoids overstating the potential benefits from increasing product
efficiency. DOE calculated the LCC and PBP for consumers of consumer clothes dryers
as if each were to purchase a new product in the first year of required compliance with
new or amended standards. New and amended standards apply to consumer clothes
dryers manufactured 3 years after the date on which any new or amended standard is
published. (42 U.S.C. 6295(m)(4)(A)(i)) Therefore, DOE used 2027 as the first year of
compliance with any amended standards for consumer clothes dryers for all the TSLs

other than TSL 3. For TSL 3, DOE used 2028 as the first year of compliance for all
product classes as specified for the Recommended TSL in the Joint Agreement.

LCC and PBP calculations. The subsections that follow provide further discussion.

approach DOE had used for the August 2022 NOPR analysis.
92
In response to the August 2022 NOPR AHAM recommended that DOE modify
the way consumer economic impact is analyzed and look at the probability that individual
consumers will benefit from standards rather than whether the aggregate benefit is
positive. (AHAM, No. 46 at p. 13)
In the LCC analysis, DOE notes that it does estimate the impact of potential
standards on individual consumers in the household sample and considers the share of
consumers that would benefit from a standard as part of its evaluation regarding whether
particular standards are economically justified.
1. Product Cost
To calculate consumer product costs, DOE multiplied the MPCs developed in the
engineering analysis by the markups described previously (along with sales taxes). DOE
used different markups for baseline products and higher efficiency products because
DOE applies an incremental markup to the increase in MSP associated with higher
efficiency products.
Economic literature and historical data suggest that the real costs of many
products may trend downward over time according to “learning” or “experience” curves.
Experience curve analysis implicitly includes factors such as efficiencies in labor, capital
investment, automation, materials prices, distribution, and economies of scale at an
industry-wide level. To derive the learning rate parameter for consumer clothes dryers,
DOE obtained historical Producer Price Index (“PPI”) data from the Bureau of Labor
Statistics (“BLS”) for “household laundry equipment” between 1947 and 2016 and
93
“major household appliance: primary products” between 2016 and 2022 to form a time
series price index representing household laundry equipment from 1947 to 2022.
57
Inflation-adjusted price indices were calculated by dividing the PPI series by the gross
domestic product index from the Bureau of Economic Analysis for the same years.
Using this data from 1947 to 2022, the estimated learning rate (defined as the fractional
reduction in price from each doubling of cumulative production) is 17.2 percent.
For this direct final rule, DOE considered comments it had received regarding the
methodology for calculating consumer product costs that were submitted in response to
the August 2022 NOPR. The approach used for this direct final rule is largely the same
approach DOE had used for the August 2022 NOPR analysis.
In response to the August 2022 NOPR, AHAM stated that DOE’s pricing
estimates are incorrect because currently, publicly available retail market prices for the
lowest-priced units (many of which are equipped with electromechanical controls) are
approximately $400, and DOE’s estimate for a baseline standard electric unit is $607.
(AHAM, No. 46 at pp. 5–6, 8)
Whirlpool stated that DOE does not consider retail prices for models actually
being sold in the market today that meet varying efficiency levels and actually utilize
technology options needed to meet TSL 3. Whirlpool commented that retail price
differences between $200 and $300 may be a better reflection of the expected price
57
“Household laundry equipment” PPI (PCU3352203352204) is available through May 2016, and “major
household appliance: primary products PPI (PCU335220335220P) is available from May 2016 to present.

94
premiums for consumers from amended standards than DOE’s analysis and methodology.
(Whirlpool, No. 53 at p. 7)
In response, DOE notes that the actual retail price differences between a baseline
and higher efficiency level currently on the market may include the price for other
premium features in addition to engineering designs relating to efficiency. Additionally,
retail prices reflect economies of scale in production as well as marketing strategies and
profit margins of manufacturers and retailers. DOE maintains that its traditional
approach, which has been subject to peer review, is better able to identify the incremental
costs that are only connected to higher efficiency. Furthermore, in this direct final rule
analysis, DOE leveraged web scraping to gather data on clothes dryer models available
on the market from January to March 2023. The data was collected from major retail
outlets, including Best Buy, Lowe’s, and AJ Madison. DOE found that the lowest-priced
baseline model cost $630. DOE therefore concluded that its baseline estimate for a
standard electric unit is reasonable for this direct final rule.
2. Installation Cost
Installation cost includes labor, overhead, and any miscellaneous materials and
parts needed to install the product. DOE used data from RSMeans Residential Cost Data
to estimate the baseline installation cost for consumer clothes dryers.
58
DOE estimated
that for the new construction market, it takes, on average, 1 hour to install a clothes dryer,
while for the replacement or new-owner market, it takes 2.5 hours (i.e., 1 hour for the trip

95
charge, 30 minutes to remove the old clothes dryer, and 1 hour to install). DOE found no
evidence that increased efficiency levels would impact installation costs.
3. Annual Energy Consumption
For each sampled household, DOE determined the energy consumption for a
consumer clothes dryer at different efficiency levels using the approach described
previously in section IV.E of this document.
4. Energy Prices
Because marginal electricity and gas prices more accurately capture the
incremental savings associated with a change in energy use from higher efficiency, they
provide a better representation of incremental change in consumer costs than average
electricity and gas prices. Therefore, DOE applied average electricity and gas prices for
the energy use of the product purchased in the no-new-standards case, and marginal
electricity and gas prices for the incremental change in energy use associated with the
other efficiency levels considered.
DOE derived electricity prices in 2022 using data from EEI Typical Bills and
Average Rates reports. Based upon comprehensive, industry-wide surveys, this semi-
annual report presents typical monthly electric bills and average kilowatt-hour costs to
the customer as charged by investor-owned utilities. For the residential sector, DOE
96
calculated electricity prices using the methodology described in Coughlin and Beraki
(2018).
59
DOE obtained data for calculating regional prices of natural gas from the EIA
publication Natural Gas.
60
This publication presents monthly volumes of natural gas
deliveries and average prices by state for residential, commercial, and industrial
customers.
DOE's methodology allows electricity and gas prices to vary by sector, region,
and season. In the analysis, variability in electricity and gas prices is chosen to be
consistent with the way the consumer economic and energy use characteristics are
defined in the LCC analysis. For consumer clothes dryers, DOE calculated weighted
average values for average and marginal electricity and gas price for the nine census
divisions. See chapter 8 of the direct final rule TSD for details.
To estimate energy prices in future years, DOE multiplied the 2022 energy prices
by the projection of annual average price changes for each of the nine census divisions
from the Reference case in AEO2023, which has an end year of 2050.
61
To estimate price
trends after 2050, the 2046–2050 average was used for all years.

5. Maintenance and Repair Costs
Repair costs are associated with repairing or replacing product components that
have failed in an appliance; maintenance costs are associated with maintaining the
operation of the product. Past rules indicate in general that small, incremental increases
in product efficiency produce no, or only minor, changes in repair and maintenance costs
compared to baseline efficiency products. 76 FR 22454.
For consumer clothes dryers, DOE derived an annualized repair rate based on
Consumer Reports data on repair and maintenance issues for consumer clothes dryers.
DOE estimated that the average repair rate (which measures the repair frequency) for
electric and gas consumer clothes dryers is 12 percent and 14 percent, respectively. The
most likely repairs concern the electromechanical control unit or the electronic control
unit. The repair costs are annualized by dividing by the average equipment lifetime of 14
years.
For this direct final rule, DOE considered comments it had received regarding the
maintenance and repair costs that were submitted in response to the August 2022 NOPR.
Whirlpool stated that DOE’s NOPR analysis failed to adequately account for the
increased repair costs associated with more advanced and expensive electronic parts in
electronic control dryers, which would be mandated through DOE's proposed standards.
Whirlpool commented that a timer replacement on an electromechanical control dryer
will be significantly cheaper than the replacement of an equivalent failed component on
an electronic control dryer, with major component differences being the timer, push-to-
98
start button, rotary switch, buzzer, appliance control unit, and user interface assembly.
(Whirlpool, No. 53 at pp. 8–9)
As previously stated, for this direct final rule, DOE has updated its methodology
for estimating repair costs and included repair costs associated with timer replacement in
both electromechanical control and electronic control dryers. Based on the information
provided by Whirlpool and a literature review, DOE estimated the repair cost to be $75
for an electromechanical control unit and $225 for an electronic control unit.
6. Product Lifetime
For consumer clothes dryers, DOE developed a distribution of lifetimes from
which specific values were assigned to the appliances in the test sample. DOE analyzed
actual lifetime in the field using a combination of historical shipments data, the stock of
the considered appliances in the American Housing Survey, and responses in a number of
RECS on the age of the appliances in the homes. The data allowed DOE to estimate a
survival function, which provided an average appliance lifetime of approximately 14
years. From the 2015 RECS to the 2020 RECS, there was a 6-percent increase in the
number of consumer clothes dryers retiring before reaching 4 years of age, and an
additional 1 percent lasting beyond 15 years. Therefore, for this direct final rule, DOE’s
estimated average lifetime for consumer clothes dryers remains 14 years, with a
distribution that includes 1 percent more dryers retiring before reaching 4 years and 2
percent more dryers remaining after 15 years and up to 30 years, compared to the NOPR
Weibull lifetime probability distribution. See chapter 8 of the direct final rule TSD for
further details.
99
7. Discount Rates
In the calculation of LCC, DOE applies discount rates appropriate to households
to estimate the present value of future operating cost savings. DOE estimated a
distribution of discount rates for consumer clothes dryers based on the opportunity cost of
consumer funds.
DOE applies weighted average discount rates calculated from consumer debt and
asset data, rather than marginal or implicit discount rates.
62
The LCC analysis estimates
net present value over the lifetime of the product, so the appropriate discount rate will
reflect the general opportunity cost of household funds, taking this time scale into
account. Given the long-time horizon modeled in the LCC, the application of a marginal
interest rate associated with an initial source of funds is inaccurate. Regardless of the
method of purchase, consumers are expected to continue to rebalance their debt and asset
holdings over the LCC analysis period, based on the restrictions consumers face in their
debt payment requirements and the relative size of the interest rates available on debts
and assets. DOE estimates the aggregate impact of this rebalancing using the historical
distribution of debts and assets.
To establish residential discount rates for the LCC analysis, DOE identified all
relevant household debt or asset classes in order to approximate a consumer’s opportunity
62
The implicit discount rate is inferred from a consumer purchase decision between two otherwise identical
goods with different first cost and operating cost. It is the interest rate that equates the increment of first
cost to the difference in net present value of lifetime operating cost, incorporating the influence of several
factors: transaction costs; risk premiums and response to uncertainty; time preferences; interest rates at
which a consumer is able to borrow or lend. The implicit discount rate is not appropriate for the LCC
analysis because it reflects a range of factors that influence consumer purchase decisions, rather than the
opportunity cost of the funds that are used in purchases.
100
cost of funds related to appliance energy cost savings. It estimated the average
percentage shares of the various types of debt and equity by household income group
using data from the Federal Reserve Board’s triennial Survey of Consumer Finances
63
(“SCF”) starting in 1995 and ending in 2019. Using the SCF and other sources, DOE
developed a distribution of rates for each type of debt and asset by income group to
represent the rates that may apply in the year in which amended standards would take
effect. DOE assigned each sample household a specific discount rate drawn from one of
the distributions. The average rate across all types of household debt and equity and
income groups, weighted by the shares of each type, is 4.3 percent. See chapter 8 of the
direct final rule TSD for further details on the development of consumer discount rates.
8. Energy Efficiency Distribution in the No-New-Standards Case
To accurately estimate the share of consumers that would be affected by a
potential energy conservation standard at a particular efficiency level, DOE’s LCC
analysis considered the projected distribution (market shares) of product efficiencies
under the no-new-standards case (i.e., the case without amended or new energy
conservation standards).
To estimate the energy efficiency distribution of consumer clothes dryers for 2027
or 2028, DOE used 2021 model data from DOE’s CCD and shipments data for consumer

clothes dryers from the ENERGY STAR program.

65
Based on the historical shipments
trend of ENERGY STAR- qualified consumer clothes dryers, DOE estimated an annual
0.47-percent and 0.02-percent increase in shipment-weighted efficiency for electric
standard and vented gas standard clothes dryers, respectively, beginning in 2021. Annual
shipment-weighted efficiency for the other product classes (which in total have less than
2.5-percent market share) is held constant. The estimated market shares for the no-new-
standards case for consumer clothes dryers are shown in Table IV.19 and Table IV.20.
See chapter 8 of the direct final rule TSD for further information on the derivation of the
efficiency distributions.

The LCC Monte Carlo simulations draw from the efficiency distributions and
randomly assign an efficiency to the consumer clothes dryers purchased by each sample
household in the no-new-standards case. The resulting percentage shares within the
sample match the market shares in the efficiency distributions.
In the August 2022 NOPR, DOE performed a random assignment of efficiency
levels to consumers in its Monte Carlo sample. While DOE acknowledges that economic
factors may play a role when consumers decide on what type of clothes dryers to install,
assignment of clothes dryer efficiency for a given installation, based solely on economic
measures such as life-cycle cost or simple payback period, most likely would not fully
and accurately reflect actual real-world installations. There are a number of market
failures discussed in the economics literature that illustrate how purchasing decisions
with respect to energy efficiency are unlikely to be perfectly correlated with energy use,
as described below. DOE maintains that the method of assignment, is a reasonable
approach, because it simulates behavior in the clothes dryer market, where market
failures result in purchasing decisions not being perfectly aligned with economic
103
interests, more realistically than relying only on apparent cost-effectiveness criteria
derived from the limited information in RECS. DOE further emphasizes that its approach
does not assume that all purchasers of consumer clothes dryers make economically
irrational decisions (i.e., the lack of a correlation is not the same as a negative
correlation). As part of the random assignment, some homes with more frequent dryer
events will be assigned higher efficiency clothes dryers, and some homes with
particularly lower dryer events will be assigned baseline units. By using this approach,
DOE acknowledges the uncertainty inherent in the data and minimizes any bias in the
analysis by using random assignment, as opposed to assuming certain market conditions
that are unsupported given the available evidence.
The following discussion provides more detail about the various market failures
that affect consumer clothes dryer purchases. First, consumers are motivated by more
than simple financial trade-offs. There are several behavioral factors that can influence
the purchasing decisions of complicated multi-attribute products, such as consumer
clothes dryers. For example, consumers (or decision makers in an organization) are
highly influenced by choice architecture, defined as the framing of the decision, the
surrounding circumstances of the purchase, the alternatives available, and how they are
presented for any given choice scenario.
66
The same consumer or decision maker may
make different choices depending on the characteristics of the decision context (e.g., the
timing of the purchase, competing demands for funds), which have nothing to do with the
characteristics of the alternatives themselves or their prices. Consumers or decision
66
Thaler, R.H., Sunstein, C.R., and Balz, J.P. (2014). “Choice Architecture” in The Behavioral
Foundations of Public Policy, Eldar Shafir (ed).
104
makers also face a variety of other behavioral phenomena including loss aversion,
sensitivity to information salience, and other forms of bounded rationality.
67
Thaler, who
won the Nobel Prize in Economics in 2017 for his contributions to behavioral economics,
and Sunstein point out that these behavioral factors are strongest when the decisions are
complex and infrequent, when feedback on the decision is muted and slow, and when
there is a high degree of information asymmetry.
68
These characteristics describe almost
all purchasing situations of appliances and equipment, including consumer clothes dryers.
The installation of a new or replacement consumer clothes dryers is done very
infrequently, as evidenced by the mean lifetime of 14 years for consumer clothes dryers.
Further, if the purchaser of the consumer clothes dryer is not the entity paying the energy
costs (e.g., a building owner and tenant), there may be little to no feedback on the
purchase. Additionally, there are systematic market failures that are likely to contribute
further complexity to how products are chosen by consumers, as explained in the
following paragraphs. The first of these market failuresthe split-incentive or principal-
agent problem—is likely to significantly affect consumer clothes dryers. The principal-
agent problem is a market failure that results when the consumer that purchases the
equipment does not internalize all of the costs associated with operating the equipment.
Instead, the user of the product, who has no control over the purchase decision, pays the
operating costs. There is a high likelihood of split-incentive problems in the case of rental

105
properties where the landlord makes the choice of what consumer clothes dryers to
install, whereas the renter is responsible for paying energy bills.
In addition to the split-incentive problem, there are other market failures that are
likely to affect the choice of consumer clothes dryer efficiency made by consumers. For
example, unplanned replacements due to unexpected failure of equipment such as a
consumer clothes dryer are strongly biased toward like-for-like replacement (i.e.,
replacing the non-functioning equipment with a similar or identical product). Time is a
constraining factor during unplanned replacements, and consumers may not consider the
full range of available options on the market, despite their availability. The consideration
of alternative product options is far more likely for planned replacements and
installations in new construction.
Additionally, Davis and Metcalf
69
conducted an experiment demonstrating that,
even when consumers are presented with energy consumption information, the nature of
the information available to consumers (e.g., from EnergyGuide labels) results in an
inefficient allocation of energy efficiency across households with different usage levels.
Their findings indicate that households are likely to make decisions regarding the
efficiency of the air conditioning equipment of their homes that do not result in the
highest net present value for their specific usage pattern (i.e., their decision is based on
imperfect information and, therefore, is not necessarily optimal). Also, most consumers

energy-efficiency labels,” Journal of the Association of Environmental and Resource Economists, 3(3),
589-625. Available at: www.journals.uchicago.edu/doi/full/10.1086/686252 (Last accessed August 1,
2023).
106
did not properly understand the labels (specifically whether energy consumption and cost
estimates were national averages or specific to their State). As such, consumers did not
make the most informed decisions. Consumer clothes dryers do not require EnergyGuide
labels, therefore energy consumption information is more difficult to determine for a
consumer, resulting in an even more inefficient allocation of energy efficiency across
households with different usage levels.
In part because of the way information is presented, and in part because of the
way consumers process information, there is also a market failure consisting of a
systematic bias in the perception of equipment energy usage, which can affect consumer
choices. Attari et al.
70
show that consumers tend to underestimate the energy use of large
energy-intensive appliances (such as air conditioners, dishwashers, and clothes dryers),
but overestimate the energy use of small appliances (such as light bulbs). Therefore, it is
possible that consumers systematically underestimate the energy use associated with
consumer clothes dryers, resulting in less cost-effective purchases.
These market failures affect a sizeable share of the consumer population. A study
by Houde
71
indicates that there is a significant subset of consumers that appear to

107
purchase appliances without taking into account their energy efficiency and operating
costs at all.
The existence of market failures in the residential sector is well supported by the
economics literature and by a number of case studies. If DOE developed an efficiency
distribution that assigned consumer clothes dryer efficiency in the no-new-standards case
solely according to energy use or economic considerations such as life-cycle cost or
payback period, the resulting distribution of efficiencies within the consumer sample
would not reflect any of the market failures or behavioral factors above. Thus, DOE
concludes such a distribution would not be representative of the consumer clothes dryer
market. Further, even if a specific household is not subject to the market failures above,
the purchasing decision of consumer clothes dryer efficiency can be highly complex and
influenced by a number of factors (e.g., aesthetics) not captured by the building
characteristics available in the RECS sample. These factors can lead to households or
building owners choosing a consumer clothes dryer efficiency that deviates from the
efficiency predicted using only energy use or economic considerations such as life-cycle
cost or payback period (as calculated using the information from RECS 2020).
There is a complex set of behavioral factors, with sometimes opposing effects,
affecting the consumer clothes dryer market. It is impractical to model every consumer
decision incorporating all of these effects at this extreme level of granularity given the
limited available data. Given these myriad factors, DOE estimates the resulting
distribution of such a model, if it were possible, would be very scattered with high
variability. It is for this reason DOE utilizes a random distribution (after accounting for
108
efficiency market share constraints) to approximate these effects. The methodology is not
an assertion of economic irrationality, but instead, it is a methodological approximation
of complex consumer behavior. The analysis is neither biased toward high or low energy
savings. The methodology does not preferentially assign lower-efficiency consumer
clothes dryers to households in the no-new-standards case where savings from the rule
would be greatest, nor does it preferentially assign lower-efficiency consumer clothes
dryers to households in the no-new-standards case where savings from the rule would be
smallest. Some consumers were assigned the clothes dryers that they would have chosen
if they had engaged in perfect economic considerations when purchasing the products.
Others were assigned less-efficient clothes dryers even where a more-efficient product
would eventually result in life-cycle savings, simulating scenarios where, for example,
various market failures prevent consumers from realizing those savings. Still others were
assigned clothes dryers that were more efficient than one would expect simply from life-
cycle costs analysis, reflecting, say, “green” behavior, whereby consumers ascribe
independent value to minimizing harm to the environment.
Therefore, for this direct final rule, DOE performed a random assignment of
efficiencies in the LCC analysis.
Additionally, for this direct final rule, DOE considered comments it received
regarding the projected distribution of product efficiencies under the no-new-standards
case that were submitted in response to the August 2022 NOPR. The CA IOUs requested
that DOE clarify the changes in efficiency distributions from the 2021 preliminary
analysis to the August 2022 NOPR analysis, specifically regarding the percentage of
109
products that meet or exceed the ENERGY STAR level in the no-new-standards case.
The CA IOUs stated that the preliminary analysis efficiency distributions resulted in a
reasonably favorable consumer impact analysis for TSL 4. The CA IOUs recommended
that DOE reconsider the analysis and conclusion regarding TSL 4 if the preliminary
analysis efficiency distributions were more accurate. (CA IOUs, No. 50 at pp. 3–4).
In the 2021 preliminary analysis, DOE utilized a consumer-choice model to
calculate market share of various efficiency options for consumer clothes dryers. This
model considered factors such as the first cost for electric standard, vented gas standard,
ventless electric compact (204V), and ventless electric washer-dryer units. The
consumer-choice model relied on historical sales data from 2005 to 2011. To project the
efficiency distribution for other product classes (electric compact (120V), vented electric
compact (240V), DOE used inputs based on its own test samples and a review of models
available in the market.
In the 2022 NOPR analysis, DOE evaluated concerns expressed by stakeholders
regarding the adequacy and representativeness of the historical sales data from 2005 to
2011. DOE recognized that these data might not accurately reflect the correlations
between shipments and sale prices in recent years. For this reason, as well as to maintain
consistency in its methodology across product classes, DOE elected to use CCD model
110
counts
72
instead of market shipments data to derive the no-new-standards case efficiency
distributions for the NOPR.
The Joint Commenters commented that the ENERGY STAR shipment data is a
better reflection of the consumer clothes dryer market than CCD model counts. The Joint
Commenters stated that according to the ENERGY STAR shipment data, only about 40
percent of electric standard dryer models meet TSL 3 as opposed to DOE's estimate of 65
percent. (Joint Commenters, No. 51 at pp. 3–4).
For this direct final rule, DOE has considered the ENERGY STAR shipment data
for standard consumer clothes dryers along with other pertinent market information. As a
result, DOE has revised the market share estimate for electric and gas standard consumer
clothes dryers meeting ENERGY STAR criteria in the compliance year. DOE reduced
market share of electric standard consumer clothes dryers that meet TSL 3 from 61
percent to 42 percent and increased market share of gas standard consumer clothes dryers
that meet TSL 3 from 38 percent to 48 percent. For the remaining product classes, which
together account for less than 2.5 percent of the total shipments, DOE has continued to
use the CCD model counts because it is not aware of other available information.
9. Payback Period Analysis
The payback period is the amount of time (expressed in years) it takes the
consumer to recover the additional installed cost of more efficient products, compared to
72
The CCD database lists basic models of certified consumer clothes dryers that are subject to DOE’s
energy conservation standards, including their rated capacities and CEF. These clothes dryer models are
submitted by manufacturers or their third-party representatives.
111
baseline products, through energy cost savings. Payback periods that exceed the life of
the product mean that the increased total installed cost is not recovered in reduced
operating expenses.
The inputs to the PBP calculation for each efficiency level are the change in total
installed cost of the product and the change in the first-year annual operating
expenditures relative to the baseline. DOE refers to this as a “simple PBP” because it
does not consider changes over time in operating cost savings. The PBP calculation uses
the same inputs as the LCC analysis when deriving first-year operating costs.
As noted previously, EPCA establishes a rebuttable presumption that a standard is
economically justified if the Secretary finds that the additional cost to the consumer of
purchasing a product complying with an energy conservation standard level will be less
than three times the value of the first year’s energy savings resulting from the standard, as
calculated under the applicable test procedure. (42 U.S.C. 6295(o)(2)(B)(iii)) For each
considered efficiency level, DOE determined the value of the first year’s energy savings
by calculating the energy savings in accordance with the applicable DOE test procedure
and multiplying those savings by the average energy price projection for the year in
which compliance with the amended standards would be required.
G. Shipments Analysis
DOE uses projections of annual product shipments to calculate the national
impacts of potential amended or new energy conservation standards on energy use, NPV,
112
and future manufacturer cash flows.
73
The shipments model takes an accounting
approach, tracking market shares of each product class and the vintage of units in the
stock. Stock accounting uses product shipments as inputs to estimate the age distribution
of in-service product stocks for all years. The age distribution of in-service product
stocks is a key input to calculations of both the NES and NPV, because operating costs
for any year depend on the age distribution of the stock.
Total product shipments for consumer clothes dryers are developed by
considering the demand from replacements for units in stock that fail and the demand
from new installations in newly constructed homes. DOE calculated shipments due to
replacements using the retirement function developed for the LCC analysis. DOE
calculated shipments due to new installations using estimates for consumer clothes dryer
saturation rates in newly constructed homes from 2015 to 2020 in the 2020 RECS and
projections of new housing starts in AEO2023.
DOE disaggregated total product shipments into each product class using
estimated market shares of each product class. To estimate these market shares, DOE first
developed a linear time series regression model to estimate market share between the
product fuel type (i.e., gas or electric) by fitting the historical shipments of gas consumer
clothes dryers. Historical shipments data showed a steady decline of market share of gas
consumer clothes dryers, from 23 percent in 2000 to 17 percent in 2022. The linear
73
DOE uses data on manufacturer shipments as a proxy for national sales, as aggregate data on sales are
lacking. In general, one would expect a close correspondence between shipments and sales.
113
regression model indicates that market share of gas consumer clothes dryers is strongly
correlated with its historical time series.
After developing the market share estimation between electric and gas consumer
clothes dryers, DOE then subtracted the estimated gas clothes dryer market share from
total shipments and divided the electric clothes dryer market share into each electric
consumer clothes dryer product class. DOE estimated that electric standard and vented
gas standard consumer clothes dryers account for approximately 84 percent and 14
percent of the total shipments during the analysis period, respectively.
To estimate shipments under a standards case, DOE considers the impacts on
shipments from changes in product purchase price and operating cost associated with
higher energy efficiency levels using a price elasticity and an efficiency elasticity. As in
the April 2021 preliminary analysis, DOE employed an efficiency elasticity rate of 0.2
percent and a price elasticity rate of -0.45 percent in its shipments model. These values
are based on analysis of aggregated data for five residential appliances: consumer clothes
washers, dishwashers, refrigerators, freezers, and room air conditioners.
74
The market
impact is defined as the difference between the product of price elasticity of demand and
the change in price due to a standard level, and the product of the efficiency elasticity and
the change in operating costs due to a standard level.

National Laboratory, LBNL-188289.
114
DOE assumed when market impact occurs (i.e., when shipments drop under a
standards case), the affected consumers would either repair their product or purchase a
used clothes dryer rather than a new one. In the repair scenario, the model assumes that
the product’s life is extended by approximately 5 years. In the used product scenario, the
model assumes the remaining average lifetime for a used clothes dryer is 7 years.
Therefore, this market impact effectively influences the decision between repairing or
replacing the product, as well as the decision between purchasing a used dryer or a new
one. See chapter 9 of the direct final rule TSD for details.
For this direct final rule, DOE considered comments it received regarding the
shipments analysis that were submitted in response to the August 2022 NOPR. Whirlpool
commented that consumers may continue replacing cheaper components well into the life
of an electromechanical controlled dryer, extending its life, while they may not decide to
make a more expensive electronic component repair, like a user interface assembly, after
several years of ownership of an electronic control dryer. Whirlpool stated that DOE's
proposed standards may effectively shorten the useful life of a consumer clothes dryer
because of this repair-versus-replacement calculus, resulting in loss of time-saving
benefits of dryer ownership. (Whirlpool, No. 53 at pp. 8–9)
As stated in section IV.C.1 of this document, the recommended standards would
continue to allow for electromechanical controlled clothes dryers to be sold on the
market. In addition, DOE is not aware of reliability issues associated with the
implementation of electronic controls relative to electromechanical controls. Whirlpool’s
assertion that the adopted standards may shorten the useful life of consumer clothes
115
dryers lacks quantitative data to support it. As stated in section IV.F.6 of this document,
DOE’s lifetime estimation is calibrated using shipments data, which include the adopted
efficiency levels of ENERGY STAR-qualified consumer clothes dryers sold in the
market. DOE’s updated Weibull lifetime distribution in this direct final rule captures the
trend of shorter lifetime and delayed replacement of consumer clothes dryers based on
the recent field data. See chapter 9 of the direct final rule TSD for details.
H. National Impact Analysis
The NIA assesses the NES and the NPV from a national perspective of total
consumer costs and savings that would be expected to result from new or amended
standards at specific efficiency levels.
75
(“Consumer” in this context refers to consumers
of the product being regulated.) DOE calculates the NES and NPV for the potential
standard levels considered based on projections of annual product shipments, along with
the annual energy consumption and total installed cost data from the energy use and LCC
analyses. For the present analysis, DOE projected the energy savings, operating cost
savings, product costs, and NPV of consumer benefits over the lifetime of consumer
clothes dryers sold from 2027 through 2056 for all TSLs other than 2028 through 2057
for TSL 3 (the Recommended TSL detailed in the Joint Agreement).
DOE evaluates the impacts of new or amended standards by comparing a case
without such standards with standards-case projections. The no-new-standards case
characterizes energy use and consumer costs for each product class in the absence of new
75

116
or amended energy conservation standards. For this projection, DOE considers historical
trends in efficiency and various forces that are likely to affect the mix of efficiencies over
time. DOE compares the no-new-standards case with projections characterizing the
market for each product class if DOE adopted new or amended standards at specific
energy efficiency levels (i.e., the TSLs or standards cases) for that class. For the
standards cases, DOE considers how a given standard would likely affect the market
shares of products with efficiencies greater than the standard.
DOE uses a spreadsheet model to calculate the energy savings and the national
consumer costs and savings from each TSL. Interested parties can review DOE’s
analyses by changing various input quantities within the spreadsheet. The NIA
spreadsheet model uses typical values (as opposed to probability distributions) as inputs.
Table IV.21 summarizes the inputs and methods DOE used for the NIA analysis
for the direct final rule. Discussion of these inputs and methods follows the table. See
chapter 10 of the direct final rule TSD for further details.

1. Product Efficiency Trends
A key component of the NIA is the trend in energy efficiency projected for the
no-new-standards case and each of the standards cases. Section IV.F.8 of this document
describes how DOE developed an energy efficiency distribution for the no-new-standards
case (which yields a shipment-weighted average efficiency) for each of the considered
product classes for the year of anticipated compliance with an amended or new standard.
To project the trend in efficiency absent amended standards for consumer clothes dryers
over the entire shipments projection period, DOE used an annual 0.47-percent and 0.02-
percent increase in shipment-weighted efficiency beginning in 2021 for electric standard
and vented gas standard consumer clothes dryers, respectively. The efficiency for the
118
other product classes remains at their 2021 shipments-weighted efficiency levels. The
approach is further described in chapter 10 of the direct final rule TSD.
For the standards cases, DOE used a “roll-up” scenario to establish the shipment-
weighted efficiency for the year that standards are assumed to become effective. In this
scenario, the market shares of products in the no-new-standards case that do not meet the
standard under consideration would “roll-up” to meet the new standard level, and the
market share of products above the standard would remain unchanged.
2. National Energy Savings
The national energy savings analysis involves a comparison of national energy
consumption of the considered products between each potential standards case (TSL) and
the case with no-new or amended energy conservation standards. DOE calculated the
national energy consumption by multiplying the number of units (stock) of each product
(by vintage or age) by the unit energy consumption (also by vintage). DOE calculated
annual NES based on the difference in national energy consumption for the no-new-
standards case and for each higher efficiency standard case. DOE estimated energy
consumption and savings based on-site energy and converted the electricity consumption
and savings to primary energy (i.e., the energy consumed by power plants to generate site
electricity) using annual conversion factors derived from AEO2023. Cumulative energy
savings are the sum of the NES for each year over the timeframe of the analysis.
Use of higher efficiency products is sometimes associated with a direct rebound
effect, which refers to an increase in utilization of the product due to the increase in
119
efficiency. DOE did not find any data on the rebound effect specific to consumer clothes
dryers, so it did not include a rebound effect in the analysis.
Separate from a direct rebound effect, DOE also assessed the potential
implications of amended standards as it relates to clothes dryer energy use, namely
whether amended standards could result in a decrease in drying performance that would
require consumers to re-run their drying cycles to achieve satisfactory drying
performance. As discussed in section II.B.2 of this document, DOE’s appendix D2 test
procedure includes a maximum FMC threshold (i.e., a dryness level threshold that much
be achieved in order to be considered a valid test cycle), which ensures that the rated
energy consumption of clothes dryers is representative of consumer expectations for
dryness. DOE testing confirmed that commercially available products achieve this FMC
dryness threshold at each of the efficiency levels considered in this direct final rule
analysis. Consequently, DOE has determined that clothes dryers that comply with the
amended standards will provide consumer-acceptable levels of dryness corresponding to
the rated energy consumption as measured by appendix D2. In the NES, therefore, DOE
assumed that the amended standards would not result in any increase in clothes dryer
usage, such as that arising from consumers re-running drying cycles.
In 2011, in response to the recommendations of a committee on “Point-of-Use
and Full-Fuel-Cycle Measurement Approaches to Energy Efficiency Standards”
appointed by the National Academy of Sciences, DOE announced its intention to use
FFC measures of energy use and greenhouse gas and other emissions in the national
impact analyses and emissions analyses included in future energy conservation standards
120
rulemakings. 76 FR 51281 (Aug. 18, 2011). After evaluating the approaches discussed
in the August 18, 2011, notice, DOE published a statement of amended policy in which
DOE explained its determination that EIA’s National Energy Modeling System
(“NEMS”) is the most appropriate tool for its FFC analysis and its intention to use NEMS
for that purpose. 77 FR 49701 (Aug. 17, 2012). NEMS is a public domain, multi-sector,
partial equilibrium model of the U.S. energy sector
76
that EIA uses to prepare its Annual
Energy Outlook. The FFC factors incorporate losses in production and delivery in the
case of natural gas (including fugitive emissions) and additional energy used to produce
and deliver the various fuels used by power plants. The approach used for deriving FFC
measures of energy use and emissions is described in appendix 10B of the direct final
rule TSD.
For this direct final rule, DOE considered comments it had received regarding the
methodology for calculating the national energy savings that was presented in the August
2022 NOPR. The approach used for this direct final rule is largely the same approach
DOE had used for the August 2022 NOPR analysis.
In response to the August 2022 NOPR, EEI stated that in the past, DOE stated
potentially using a captured-energy approach when estimating upstream full-fuel-cycle
energy savings; however, EEI noted that in recent notices and rulemakings, DOE is now
76

April 20, 2023).
121
overstating these estimates by using a fossil fuel equivalent for renewable energy,
significantly overstating the upstream savings. (EEI, No. 37 at pp. 45–46)
As previously mentioned, DOE converts electricity consumption and savings to
primary energy and FFC energy using annual conversion factors derived from the AEO.
Traditionally, EIA has used the fossil fuel equivalency approach to report
noncombustible renewables’ contribution to total primary energy. The fossil fuel
equivalency approach applies an annualized weighted average heat rate for fossil fuel
power plants to the electricity generated (in kWh) from noncombustible renewables. EIA
recognizes that using captured energy (i.e., the net energy available for direct
consumption after transformation of a noncombustible renewable energy into electricity)
and using incident energy (i.e., the mechanical, radiation, or thermal energy that is
measurable as the “input” to the device) are possible approaches for converting
renewable electricity to a common measure of primary energy, but it continues to use the
fossil fuel equivalency approach in the AEO and other reporting of energy statistics.
DOE has used this approach to accounting for primary energy savings from energy
efficiency standards for the entirety of the appliance standards program.
Whirlpool commented that the lessening of utility and performance of dryers,
including increases to drying cycle times and potentially increased fabric damage to
clothes, may lead to corresponding compensatory behavioral changes from consumers
that may result in lost energy savings. Whirlpool recommended that DOE’s analysis
account for possible negative rebound effects of changes, such that the expected energy
savings from an amended standard may not be fully delivered over the analyzed period.
122
Whirlpool commented that consumers associate longer drying times with more potential
damage to their clothes and may choose cycles or options that reduce overall drying time
at the expense of energy consumption. (Whirlpool, No. 53 at p. 6)
DOE has examined the potential impacts on different attributes of product
performance while considering amended standards, as detailed in section IV.C.1 of this
document. As discussed further in section V.B.4 of this document, DOE data indicate
that the standards adopted by this direct final rule will not necessitate any substantive
increase in cycle times compared to typical cycle times currently associated with baseline
consumer clothes dryers and therefore are not expected to have any negative impacts on
fabric care and product wear and tear that would lead consumers to use more energy
consumptive drying cycles. Moreover, DOE notes that the appendix D2 test procedure,
which will be required to demonstrate compliance with the amended standards
established in this direct final rule, and is currently required for ENERGY STAR
certification, ensures that clothes dryers provide a consumer-acceptable level of dryness.
Furthermore, as previously discussed, on February 14, 2024, DOE received a
second joint statement from the same group of stakeholders that submitted the Joint
Agreement (including AHAM, of which Whirlpool is a member) in which the signatories
reaffirmed the standards recommended in the Joint Agreement.
77
In particular, the letter
states that the stakeholders do not anticipate the recommended standards will negatively
affect features or performance, including cycle time. In particular, the signatories stated
77
This document is available in the docket at: www.regulations.gov/comment/EERE-2014-BT-STD-0058-
0058.
123
that because the test procedure that will be used to determine compliance with amended
standards (i.e., appendix D2) requires that dryers meet a threshold for “final moisture
content” in order to be certified as compliant, this final moisture content requirement
ensures that compliant clothes dryers will adequately dry clothes. The signatories further
noted that there are more than 400 electric clothes dryer models and nearly 200 gas
clothes dryer models that are certified to the current ENERGY STAR specification,
which is equivalent to the recommended standard levels and is based on appendix D2,
and that these models all meet the final moisture content threshold specified in appendix
D2. For further discussion of consumer clothes dryer performance as it relates to
amended standards, see section V.B.4 of this document.
DOE acknowledges that this conclusion is contrary to its assumptions in the final
rule that it published on December 16, 2020 (“December 2020 Final Rule”). 85 FR
81359. There, DOE assumed that consumers might need to re-run their clothes washers
or dryers through multiple cycles “to adequately clean or dry their clothing.” 85 FR
81365. In this rulemaking, DOE has found no evidence suggesting that consumers are
running their dryers multiple times at TSL 3 (i.e., the Recommended TSL), which
corresponds to the current ENERGY STAR efficiency level for both electric and gas
standard clothes dryers. As supported by data described in section IV.E of this document,
average consumer usage of electric standard clothes has steadily declined from 301
cycles per year per dryer in the 2005 RECS to 213 cycles per year per dryer in the 2020
RECS, and vented gas standard clothes dryer usage has declined from 292 cycles in the
2005 RECS to 213 cycles in the 2020 RECS, while the average household size has
remained essentially unchanged (average 3 household members) during the same period.
124
This shows a significant downward trend in the average number of cycles run on each
consumer clothes dryer over the past 15 years, even after the implementation of the
current amended standard in 2015. These data indicate that amended energy conservation
standards have not resulted in consumers increasing dryer usage due to amended
standards for consumer clothes dryers.
Given that there is no evidence of any previous consumer clothes dryer standard
increasing drying cycles per year, and in fact, instead cycles per year have decreased over
time through multiple standards, DOE determines that a standard at the Recommended
TSL would not be expected to lead consumers to increase their use of consumer clothes
dryers.
3. Net Present Value Analysis
The inputs for determining the NPV of the total costs and benefits experienced by
consumers are (1) total annual installed cost, (2) total annual operating costs (energy
costs and repair and maintenance costs), and (3) a discount factor to calculate the present
value of costs and savings. DOE calculates net savings each year as the difference
between the no-new-standards case and each standards case in terms of total savings in
operating costs versus total increases in installed costs. DOE calculates operating cost
savings over the lifetime of each product shipped during the projection period.
As discussed in section IV.F.1 of this document, DOE developed consumer
clothes dryer price trends based on historical PPI data. DOE applied the same trends to
project prices for each product class at each considered efficiency level. By 2057, which
125
is the end date of the projection period for the Recommended TSL detailed in Joint
Agreement, the average consumer clothes dryer (real) price is projected to drop 18
percent relative to 2022. DOE’s projection of product prices is described in appendix
10C of the direct final rule TSD.
To evaluate the effect of uncertainty regarding the price trend estimates, DOE
investigated the impact of different product price projections on the consumer NPV for
the considered TSLs for consumer clothes dryers. In addition to the default price trend,
DOE considered two product price sensitivity cases: (1) a high-price-decline case based
on the combined price index from 1980 to 2022
78
and (2) a constant price trend at the
2022 value. The derivation of these price trends and the results of these sensitivity cases
are described in appendix 10C of the direct final rule TSD.
The energy cost savings are calculated using the estimated energy savings in each
year and the projected price of the appropriate form of energy. To estimate energy prices
in future years, DOE multiplied the average national energy prices by the projection of
annual national-average residential energy price changes in the Reference case from
AEO2023, which has an end year of 2050. To estimate price trends after 2050, the 2046–
2050 average was used for all years. As part of the NIA, DOE also analyzed scenarios
that used inputs from variants of the AEO2023 Reference case that have lower and higher
economic growth. Those cases have lower and higher energy price trends compared to
78
DOE combined PPI data of “household laundry equipment” from 1948 to 2016 and PPI data of “major
household appliance: primary products” from 2016 to 2022 into one time-series price index to project
future price for consumer clothes dryers.
126
the Reference case. NIA results based on these cases are presented in appendix 10D of
the direct final rule TSD.
In calculating the NPV, DOE multiplies the net savings in future years by a
discount factor to determine their present value. For this direct final rule, DOE estimated
the NPV of consumer benefits using both a 3-percent and a 7-percent real discount rate.
DOE uses these discount rates in accordance with guidance provided by the OMB to
Federal agencies on the development of regulatory analysis.
79
The discount rates for the
determination of NPV are in contrast to the discount rates used in the LCC analysis,
which are designed to reflect a consumer’s perspective. The 7-percent real value is an
estimate of the average before-tax rate of return to private capital in the U.S. economy.
The 3-percent real value represents the “social rate of time preference,” which is the rate
at which society discounts future consumption flows to their present value.
I. Consumer Subgroup Analysis
In analyzing the potential impact of new or amended energy conservation
standards on consumers, DOE evaluates the impact on identifiable subgroups of
consumers that may be disproportionately affected by a new or amended national
standard. The purpose of a subgroup analysis is to determine the extent of any such
disproportional impacts. DOE evaluates impacts on particular subgroups of consumers
by analyzing the LCC impacts and PBP for those particular consumers from alternative
79
U.S. Office of Management and Budget. Circular A-4: Regulatory Analysis. Available at
www.whitehouse.gov/omb/information-for-agencies/circulars/ (last accessed April 20, 2023). DOE used
the prior version of Circular A-4 (2003) as a result of the effective date of the new version.
.
127
standard levels. For this direct final rule, DOE analyzed the impacts of the considered
standard levels on two subgroups: (1) low-income households and (2) senior-only
households. The analysis used subsets of the 2020 RECS sample composed of
households that meet the criteria for the considered subgroups. DOE used the LCC and
PBP spreadsheet model to estimate the impacts of the considered efficiency levels on
these subgroups. Chapter 11 in the direct final rule TSD describes the consumer
subgroup analysis.
For this direct final rule, DOE considered comments it received regarding the
consumer subgroup analysis that were submitted in response to the August 2022 NOPR.
DOE notes that although several of the comments discussed below are from AHAM, as
previously discussed, on February 14, 2024, DOE received a second joint statement from
the same group of stakeholders that submitted the Joint Agreement (including AHAM) in
which the signatories reaffirmed the standards recommended in the Joint Agreement.
80
In
particular, the letter states that “the recommended standards represent the maximum
levels of efficiency that are technologically feasible and economically justified.”
(emphasis added).
In response to the August 2022 NOPR, AHAM stated that in a recent consumer
study conducted by Bellomy Research for AHAM, low-income households were at a
disadvantage when purchasing or replacing a laundry appliance, with many households
indicating that they would have to make financial sacrifices in other areas of their lives to
80

0058.
128
accommodate purchasing a dryer. AHAM stated that over 90 percent of low-income
households cited cost as the most important factor when deciding to purchase a dryer, and
nearly 75 percent of low-income households indicated they would not be willing to pay
around $100 more for a more efficient appliance at the time of purchase to save
approximately $50–$150 in energy costs over the lifetime of that appliance. AHAM
stated that one in four low-income households indicated they would delay a replacement
purchase if their laundry appliance stopped working, and in cases of replacement, they
would replace it with another entry-level/value-tier model. Additionally, AHAM stated
that over half of low-income households indicated they would turn to purchasing a used
dryer or apply for assistance. (AHAM, No. 46 at pp. 6–7). AHAM stated that standards
that result in increased prices for entry-level appliances or that price some consumers out
of the clothes dryer market by eliminating technology options that allow manufacturers to
produce entry-level models (e.g., electromechanical controls) deepen inequity for
underserved communities. According to AHAM, if low-income consumers do not have
equitable access, they may forego dryer ownership and use a laundromat with lost time
savings and additional operating costs, rely on expensive financing options, or buy an
older and possibly less efficient used dryer, thus reducing overall savings potential.
(AHAM, No. 46 at pp. 5–6, 8)
AGA and APGA supported AHAM's comments on the disproportionate effect
more stringent standards could have on low-income consumers. (AGA et al., No. 47 at p.
4)
129
Whirlpool stated that low-income consumers may not be able to purchase more
efficient dryers due to the significant cost increase and their inability to pay for very large
emergency purchases over $500. Whirlpool stated that while there may be some level of
life-cycle cost savings from proposed standards, consumers who can no longer afford an
entry-level dryer may never realize these savings. Whirlpool stated that purchase price
increases driven by DOE's proposed standards may drive undesirable consumer behavior,
including repairing the old dryer or purchasing a used dryer, effectively keeping older
and less efficient appliances on the grid. Whirlpool requested that DOE ensure new
appliances remain as affordable to low-income consumers as possible. (Whirlpool, No.
53 at pp. 7–8)
NYSERDA stated that amended standards would significantly improve energy
outcomes for low-income households and not create additional burdens. NYSERDA
stated that in New York, there is a relatively even split between owner-occupied and
rented homes, with a significant number of rental properties, especially in new
construction, having in-unit consumer clothes dryers. NYSERDA commented that for
individual renters who are not responsible for the purchase of their clothes dryer but who
are responsible for paying their utility bills, amended standards will provide utility bill
savings without incurring direct equipment costs. (NYSERDA, No. 48 at p. 2)
According to the 2020 RECS clothes dryer sample, approximately 47 percent of
low-income households who have a dryer are renters. In most cases, the property owner
would purchase a new dryer. While the owner might seek to collect some of this cost in
rent, the ability to do so is constrained by lease agreements and larger market forces that
130
influence rent levels in particular locations. Thus, it is reasonable to conclude that renters
would see a significant net benefit from a higher efficiency dryer, and this is seen in the
results of DOE’s analysis (see section V.B.1.b of this document for results of the
consumer subgroup analysis). Additionally, for this direct final rule, DOE implemented a
scenario assuming that landlords would pass some of the incremental clothes dryer costs
to renters in the LCC analysis. The results indicate that this scenario would not impact
DOE’s decision on adopting the amended standards. For details of the sensitivity results,
see appendix 11A of the direct final rule TSD.
In DOE’s analysis, approximately 53 percent of low-income households who
have a dryer are homeowners, who would be responsible for purchasing a new dryer.
Given that the average incremental increase in price for a dryer meeting the adopted
standards (relative to the baseline model that reflects current entry-level products) is $27,
DOE believes it is reasonable to conclude that most low-income homeowners who could
afford to purchase a new dryer under the current standard could also afford to purchase a
dryer that meets the new standard, particularly in the absence of data indicating
otherwise. Furthermore, DOE’s analysis found that for the largest product class (i.e.,
electric standard), less than 1 percent of low-income households would experience a net
cost under the adopted standard, but the majority would see a net benefit (see section
V.B.1.b of this document for results of the consumer subgroup analysis).
In total, DOE’s analysis estimated that 45 percent of low-income households who
have a dryer would experience a net benefit and 54 percent of low-income households
who have a dryer would have no impact under the adopted standard.
131
AHAM comment in response to the August 2022 NOPR that low-income
consumers might lose equitable access to on-site dryer usage because of the amended
standards did not include supporting data so DOE was unable to fully evaluate the
assertion. Nevertheless, DOE’s shipments analysis takes into account the market impact
under a standards case. For this direct final rule, DOE has implemented scenarios in
which affected consumers would either repair their clothes dryers or opt to purchase a
used one instead of a new clothes dryer (see section IV.G of this document).
AHAM recommended that DOE review all available data sources regarding low-
income households and appliances to incorporate into its low-income analysis, in
particular the basis of only differential discount rates. AHAM commented that DOE’s
analysis is a very myopic view of the effects of standards on low-income households, and
within this framework the approach of using average discount rates is fundamentally
flawed in its understanding of the relationship between disposable income and balance
sheet rebalancing. (AHAM, No. 46 at p. 8)
DOE’s approach to the low-income consumer subgroup analysis includes
households that do not have assets or debts included in the SCF. It is likely that a
majority of these “unbanked” households primarily rely on cash to complete transactions
and as a form of savings, which is included in the distribution of discount rates associated
with low-income consumers. Consumers that rely entirely on cash are assigned a discount
rate of 0 percent, as there is no lost opportunity cost from alternative noncash assets or
debts. For households that utilize nontraditional, nonbank financing, DOE’s methodology
includes a distribution of high discount rates (i.e., >10% percent), which are
132
representative of the opportunity cost associated with nonbank lines of credit. Therefore,
DOE determined that this comprehensive approach enables a fair assessment of discount
rates for low-income consumers who have different financial situations.
J. Manufacturer Impact Analysis
1. Overview
DOE performed an MIA to estimate the financial impacts of amended energy
conservation standards on manufacturers of consumer clothes dryers and to estimate the
potential impacts of such standards on direct employment and manufacturing capacity.
The MIA has both quantitative and qualitative aspects and includes analyses of projected
industry cash flows, the INPV, investments in research and development (“R&D”) and
manufacturing capital, and domestic manufacturing employment. Additionally, the MIA
seeks to determine how amended energy conservation standards might affect
manufacturing employment, capacity, and competition, as well as how standards
contribute to overall regulatory burden. Finally, the MIA serves to identify any
disproportionate impacts on manufacturer subgroups, including small business
manufacturers.
The quantitative part of the MIA primarily relies on the GRIM, an industry cash
flow model with inputs specific to this rulemaking. The key GRIM inputs include data
on the industry cost structure, unit production costs, product shipments, manufacturer
markups, and investments in R&D and manufacturing capital required to produce
compliant products. The key GRIM outputs are the INPV, which is the sum of industry
annual cash flows over the analysis period, discounted using the industry-weighted
133
average cost of capital, and the impact on domestic manufacturing employment. The
model uses standard accounting principles to estimate the impacts of more stringent
energy conservation standards on a given industry by comparing changes in INPV and
domestic manufacturing employment between a no-new-standards case and the various
standards cases. To capture the uncertainty relating to manufacturer pricing strategies
following amended standards, the GRIM estimates a range of possible impacts under
different markup scenarios.
The qualitative part of the MIA addresses manufacturer characteristics and market
trends. Specifically, the MIA considers such factors as a potential standard’s impact on
manufacturing capacity, competition within the industry, the cumulative impact of other
DOE and non-DOE regulations, and impacts on manufacturer subgroups. The complete
MIA is outlined in chapter 12 of the direct final rule TSD.
DOE conducted the MIA for this rulemaking in three phases. In Phase 1 of the
MIA, DOE prepared a profile of the consumer clothes dryer manufacturing industry
based on the market and technology assessment, preliminary manufacturer interviews,
and publicly available information. This included a top-down analysis of consumer
clothes dryer manufacturers that DOE used to derive preliminary financial inputs for the
GRIM (e.g., revenues; materials, labor, overhead, and depreciation expenses; selling,
general, and administrative expenses (“SG&A”); and R&D expenses). DOE also used
public sources of information to further calibrate its initial characterization of the
consumer clothes dryer manufacturing industry, including company filings of form 10-K
134
from the SEC,
81
corporate annual reports, the U.S. Census Bureau’s Quarterly Survey of
Plant Capacity Utilization,
82
the U.S. Census Bureau’s Annual Survey of Manufactures
(“ASM”),
83
and reports from Dun & Bradstreet.
84
In Phase 2 of the MIA, DOE prepared a framework industry cash-flow analysis to
quantify the potential impacts of amended energy conservation standards. The GRIM
uses several factors to determine a series of annual cash flows starting with the
announcement of the standard and extending over a 30-year period following the
compliance date of the standard. These factors include annual expected revenues, costs
of sales, SG&A and R&D expenses, taxes, and capital expenditures. In general, energy
conservation standards can affect manufacturer cash flow in three distinct ways:
(1) creating a need for increased investment, (2) raising production costs per-unit, and (3)
altering revenue due to higher per-unit prices and changes in sales volumes.
In addition, during Phase 2, DOE developed interview guides to distribute to
manufacturers of consumer clothes dryers in order to develop other key GRIM inputs,
including product and capital conversion costs, and to gather additional information on
the anticipated effects of energy conservation standards on revenues, direct employment,
capital assets, industry competitiveness, and subgroup impacts.

135
In Phase 3 of the MIA, DOE conducted structured, detailed interviews with
representative manufacturers. During these interviews, DOE discussed engineering,
manufacturing, procurement, and financial topics to validate assumptions used in the
GRIM and to identify key issues or concerns. As part of Phase 3, DOE also evaluated
subgroups of manufacturers that may be disproportionately impacted by amended
standards or that may not be accurately represented by the average cost assumptions used
to develop the industry cash flow analysis. Such manufacturer subgroups may include
small business manufacturers, low-volume manufacturers, niche players, and/or
manufacturers exhibiting a cost structure that largely differs from the industry average.
DOE identified one subgroup for a separate impact analysis: small business
manufacturers. The small business subgroup is discussed in chapter 12 of the direct final
rule TSD.
2. Government Regulatory Impact Model and Key Inputs
DOE uses the GRIM to quantify the changes in cash flow due to amended
standards that result in a higher or lower industry value. The GRIM uses a standard,
annual discounted cash-flow analysis that incorporates manufacturer costs, manufacturer
markups, shipments, and industry financial information as inputs. The GRIM models
changes in costs, distribution of shipments, investments, and manufacturer margins that
could result from an amended energy conservation standard. The GRIM spreadsheet uses
the inputs to arrive at a series of annual cash flows, beginning in 2024 (the base year of
the analysis) and continuing 30 years from the analyzed compliance year.
85
DOE
85
For the no-new-standards case and all TSLs except the Recommended TSL (i.e., TSL 3), the analysis
period ranges from 2024-2056. For the Recommended TSL, the analysis period ranges from 20242057.
136
calculated INPVs by summing the stream of annual discounted cash flows during this
period. For manufacturers of consumer clothes dryers, DOE used a real discount rate of
7.5 percent, which was derived from industry financials and then modified according to
feedback received during manufacturer interviews.
The GRIM calculates cash flows using standard accounting principles and
compares changes in INPV between the no-new-standards case and each standards case.
The difference in INPV between the no-new-standards case and a standards case
represents the financial impact of the amended energy conservation standard on
manufacturers. As discussed previously, DOE developed the critical GRIM inputs using
a number of sources, including publicly available data, results of the engineering analysis
and shipments analysis, and information gathered from industry stakeholders during the
course of manufacturer interviews. The GRIM results are presented in section V.B.2 of
this document. Additional details about the GRIM, the discount rate, and other financial
parameters can be found in chapter 12 of the direct final rule TSD.
a. Manufacturer Production Costs
Manufacturing more efficient products is typically more expensive than
manufacturing baseline products due to the use of more complex components, which are
typically more costly than baseline components. The changes in MPCs of covered
products can affect the revenues, gross margins, and cash flow of the industry. DOE
models the relationship between efficiency and MPCs as a part of its engineering
analysis. For a complete description of the MPCs, see section IV.C of this document and
chapter 5 of the direct final rule TSD.
137
b. Shipments Projections
The GRIM estimates manufacturer revenues based on total unit shipment
projections and the distribution of those shipments by efficiency level. Changes in sales
volumes and efficiency mix over time can significantly affect manufacturer finances. For
this analysis, the GRIM uses the NIA’s annual shipment projections derived from the
shipments analysis from the base year (2024) to the end year of the analysis period (30
years from the analyzed compliance date
86
). See section IV.G of this document and
chapter 9 of the direct final rule TSD for additional details.
c. Capital and Product Conversion Costs
Amended energy conservation standards could cause manufacturers to incur
conversion costs to bring their production facilities and product designs into compliance.
DOE evaluated the level of conversion-related expenditures that would be needed to
comply with each considered efficiency level in each product class. For the MIA, DOE
classified these conversion costs into two major groups: (1) capital conversion costs and
(2) product conversion costs. Capital conversion costs are investments in property, plant,
and equipment necessary to adapt or change existing production facilities such that new
compliant product designs can be fabricated and assembled. Product conversion costs are
investments in research, development, testing, marketing, and other non-capitalized costs
necessary to make product designs comply with amended energy conservation standards.
86
Id.
138
DOE relied on manufacturer feedback to evaluate the level of capital and product
conversion costs manufacturers would likely incur at the various TSLs. During
confidential interviews, DOE asked manufacturers to estimate the capital conversion
costs (e.g., changes in production processes, equipment, and tooling) to meet the various
efficiency levels. DOE also asked manufacturers to estimate the redesign effort and
engineering resources required at various efficiency levels to quantify the product
conversion costs. Based on manufacturer feedback, DOE also estimated “re-flooring
costs associated with replacing obsolete display models in big-box stores (e.g., Lowe’s,
Home Depot, Best Buy) due to higher standards. Some manufacturers stated that with a
new product release, big-box retailers discount outdated display models, and
manufacturers share any losses associated with discounting the retail price. The
estimated re-flooring costs for each efficiency level were incorporated into the product
conversion cost estimates, as DOE modeled the re-flooring costs as a marketing expense.
DOE reviewed the DOE CCD,
87
U.S. market share estimates, and company
characteristics to scale the company-specific conversion cost estimates to levels that
represent the overall industry. First, DOE used data from its CCD,
88
the ENERGY
STAR-qualified product database,
89
and the California Energy Commission database
90
to
identify original equipment manufacturers (“OEMs”) of the covered products. Next,
DOE assessed each OEM’s U.S. market share and product profile (e.g., estimated sales

139
by product class and efficiency) for consumer clothes dryers. Finally, DOE estimated
industry-level conversion cost estimates by scaling feedback from OEMs based on a
combination of product offerings and U.S. market share estimates.
DOE adjusted the conversion cost estimates developed in support of the August
2022 NOPR to 2022$ for this analysis. DOE also estimated industry costs associated
with appendix D2, as finalized in the October 2021 TP Final Rule. 86 FR 56608.
In general, DOE assumes all conversion-related investments occur between the
year of publication of the final rule and the year by which manufacturers must comply
with the new standard. The conversion cost figures used in the GRIM can be found in
section V.B.2.a of this document. For additional information on the estimated capital and
product conversion costs, see chapter 12 of the direct final rule TSD.
d. Manufacturer Markup Scenarios
MSPs include direct manufacturing production costs (i.e., labor, materials, and
overhead estimated in DOE’s MPCs) and all non-production costs (i.e., SG&A, R&D,
and interest), along with profit. To calculate the MSPs in the GRIM, DOE applied
manufacturer markups to the MPCs estimated in the engineering analysis for each
product class and efficiency level. Modifying these markups in the standards case yields
different sets of impacts on manufacturers. For the MIA, DOE modeled two standards-
case scenarios to represent uncertainty regarding the potential impacts on prices and
profitability for manufacturers following the implementation of amended energy
conservation standards: (1) a preservation of gross margin percentage scenario and (2) a
140
preservation-of-operating profit scenario. These scenarios lead to different manufacturer
markup values that, when applied to the MPCs, result in varying revenue and cash flow
impacts.
Under the preservation of gross margin percentage scenario, DOE applied a single
uniform “gross margin percentage” across all efficiency levels, which assumes that
manufacturers would be able to maintain the same amount of profit as a percentage of
revenues at all efficiency levels within a product class. As manufacturer production costs
increase with efficiency, this scenario implies that the per-unit dollar profit will increase.
DOE assumed a gross margin percentage of approximately 21 percent for all product
classes.
91
Manufacturers tend to believe it is optimistic to assume that they would be able
to maintain the same gross margin percentage as their production costs increase,
particularly for minimally efficient products. Therefore, this scenario represents a high
bound to industry profitability under an amended energy conservation standard.
Under the preservation of operating profit scenario, DOE modeled a situation in
which manufacturers are not able to increase per-unit operating profit in proportion to
increases in manufacturer production costs. DOE implemented this scenario in the
GRIM by lowering the manufacturer markups at each TSL to yield approximately the
same earnings before interest and taxes in the standards case as in the no-new-standards
case in the year after the compliance date of the amended standards. The implicit
91
The gross margin percentage of 21 percent is based on a manufacturer markup of 1.26.
141
assumption behind this scenario is that the industry can only maintain its operating profit
in absolute dollars after the standard.
A comparison of industry financial impacts under the two manufacturer markup
scenarios is presented in section V.B.2.a of this document.
3. Discussion of MIA Comments
For this direct final rule, DOE considered comments it had received regarding its
manufacturer impact analysis presented in the August 2022 NOPR. The approach used
for this direct final rule is largely the same as the approach DOE had used for the August
2022 NOPR analysis.
AHAM requested that DOE confirm it has fully included all costs that
manufacturers would face in compliance to assure that the financial effects on
manufacturers are not excessive. (AHAM, No. 46 at p. 11)
As discussed in section IV.J.2.c of this document, DOE primarily relied on
manufacturer feedback to estimate the capital and product conversion costs that
manufacturers would likely incur at the various analyzed efficiency levels. DOE did not
receive additional feedback about its conversion cost estimates published in the August
2022 NOPR. Therefore, DOE did not significantly alter its conversion cost methodology
in evaluating this direct final rule. DOE adjusted the conversion cost estimates developed
in support of the NOPR to 2022$ for this analysis. Additionally, for this direct final rule,
DOE updated its product conversion cost estimates to incorporate the estimated industry
142
costs associated with rerating basic models in accordance with appendix D2. 86 FR
56608.
AHAM stated that if DOE is to consider amending energy conservation standards,
it must incorporate into its analysis the challenges manufacturers are facing regarding the
COVID-19 pandemic and increased tariffs. AHAM commented that DOE cannot simply
rely on its previous analysis regarding component costs. (AHAM, No. 46 at pp. 13–14)
For this direct final rule, DOE updated its engineering analysis to incorporate up-
to-date cost estimates. Increased costs associated with recent supply chain challenges
stemming from the COVID-19 pandemic have been incorporated into the cost analysis by
way of 5-year moving averages for materials and the most up-to-date costs for purchased
parts.
AHAM stated that there will be an additional design cycle for either or both
clothes washers and clothes dryers if the effective dates for the two products are out of
sync. AHAM stated that the existing DOE analysis does not capture this situation, which
creates a significant technical and financial burden on manufacturers. (AHAM, No. 46 at
p. 11) AHAM stated its support for the ongoing Peer Review process regarding
cumulative regulatory burden and stated that DOE should not discount the time and
resources needed to evaluate and respond to all proposed test procedures and energy
conservation standards for multiple products proposed over a short period. AHAM
commented that when these rulemakings occur simultaneously, the cumulative burden
increases dramatically. (AHAM, No. 46 at p. 13)
143
DOE notes that it is adopting the Recommended TSL in this direct final rule. The
Joint Agreement included recommendations for other appliance standards rulemakings:
residential clothes washers; consumer clothes dryers; consumer conventional cooking
products; dishwashers; refrigerators, refrigerator-freezers, and freezers; and
miscellaneous refrigeration products. The signatories indicate that the Joint Agreement
for the six rulemakings should be considered as a joint recommendation of standards, to
be adopted in its entirety. (Joint Agreement, No. 55 at p. 3) The Joint Agreement
specifies a compliance date of March 1, 2028 for both residential clothes washers and
consumer clothes dryers. Therefore, DOE did not adjust its conversion cost estimates to
account for the time and investments associated with an additional design cycle as DOE
assumed the compliance dates for residential clothes washers and consumer clothes
dryers would align.
AHAM urged DOE to incorporate the financial results of the current cumulative
regulatory burden analysis directly into the MIA and stated that this is achievable by
adding the combined costs of complying with multiple regulations into the Product
Conversion Costs in the GRIM model and including the costs to manufacturers of
responding to and monitoring regulations. (AHAM, No. 46 at p. 11) AHAM requested
that DOE explicitly recognize the industry effects of multiple regulations issued within a
short period of time on the same product. AHAM stated that the MIA inherently assumes
the regulation analyzed in the INPV analysis is a single event (investment) and that all
other cash flows are unaffected by this regulation. In addition, AHAM stated that when
there are multiple regulations on the same product within the 6-year lock-in period, the
second regulation violates the recoupment assumption inherent in the first one, which is
144
not considered by the GRIM model. AHAM stated that DOE could resolve this by
conducting a consolidated analysis for multiple regulations starting from the time of the
first regulation or by incorporating a value reduction factor in the first post-regulation
year of the analysis that subtracts the value lost from the remaining years of the previous
regulation. (Id. at pp. 11–12)
If DOE were to combine the conversion costs from multiple regulations, as
requested, it would be appropriate to match the combined conversion costs with the
combined revenues of the regulated products. DOE is concerned that combined results
would make it more difficult to discern the direct impact of the amended standard on
covered manufacturers, particularly for rulemakings where there is only partial overlap of
manufacturers. Conversion costs would be spread over a larger revenue base and result in
less severe INPV impacts when evaluated on a percent change basis. Furthermore, DOE
is not aware of other Federal, product-specific regulations on consumer clothes dryers
that would go into effect 3 years before or after the 2028 compliance date. DOE
understands that if the effective dates of the consumer clothes dryer and residential
clothes washer amended standards were misaligned, there could be additional
development and marketing costs associated with aligning the design cycles of these
products, as clothes dryers and clothes washers are typically designed and sold in pairs.
However, DOE did not account for any additional development cost associated with this
potential regulatory burden, as DOE modeled the recommended March 1, 2028
compliance date from the Joint Agreement for both rulemakings.
145
AHAM urged DOE to weigh in against regulatory misalignment with Natural
Resources Canada (“NRCan”) through the United States-Canada Regulatory Cooperation
Council work plan on energy efficiency and under the Memorandum of Understanding
("MOU") on energy cooperation. AHAM also urged DOE to account for the burden of
any misalignment in its analysis. According to AHAM, it is critical that amended
standards are coordinated with NRCan, in both substance and timing, to maintain a
consistent United States-Canadian market for home appliances. (AHAM, No. 46 at p. 13)
As part of the analysis underlying the energy conservation standards for consumer
clothes dryers, DOE considers and reviews standards programs from other regions. As
part of this effort, DOE considers regulatory actions undertaken by NRCan and notes that
per a notice published on April 2, 2022 in the Canada Gazette, Part I,
92
NRCan is
currently proceeding with pre-consultations to align the energy efficiency and testing
standard for five home appliance categories including consumer clothes dryer with the
outcomes of the current DOE regulatory efforts. Further detail regarding DOE’s review
of the NRCan regulatory actions and those in other regions are discussed in chapter 3 of
the direct final rule TSD.
K. Emissions Analysis

146
component estimates the impacts of potential standards on emissions of two additional
greenhouse gases, CH
4
and N
2
O, as well as the reductions in emissions of other gases due
to “upstream” activities in the fuel production chain. These upstream activities comprise
extraction, processing, and transporting fuels to the site of combustion.
The analysis of electric power sector emissions of CO
2
, NO
X
, SO
2
, and Hg uses
emissions intended to represent the marginal impacts of the change in electricity
consumption associated with amended or new standards. The methodology is based on
results published for the AEO, including a set of side cases that implement a variety of
efficiency-related policies. The methodology is described in appendix 13A in the direct
final rule TSD. The analysis presented in this notice uses projections from AEO2023.
Power sector emissions of CH
4
and N
2
O from fuel combustion are estimated using
Emission Factors for Greenhouse Gas Inventories published by the Environmental
Protection Agency (EPA).

The on-site operation of consumer clothes dryers involves combustion of fossil
fuels and results in emissions of CO

FFC upstream emissions, which include emissions from fuel combustion during
extraction, processing, and transportation of fuels, and “fugitive” emissions (direct

, are estimated based on the methodology
described in chapter 15 of the direct final rule TSD.
The emissions intensity factors are expressed in terms of physical units per MWh
or MMBtu of site energy savings. For power sector emissions, specific emissions
intensity factors are calculated by sector and end use. Total emissions reductions are
estimated using the energy savings calculated in the national impact analysis.
1. Air Quality Regulations Incorporated in DOE’s Analysis
DOE’s no-new-standards case for the electric power sector reflects the AEO,
which incorporates the projected impacts of existing air quality regulations on emissions.
AEO2023 generally represents current legislation and environmental regulations,
including recent government actions, that were in place at the time of preparation of
AEO2023, including the emissions control programs discussed in the following
paragraphs.
95
SO
2
emissions from affected electric generating units (“EGUs”) are subject to
nationwide and regional emissions cap-and-trade programs. Title IV of the Clean Air Act
sets an annual emissions cap on SO
2
for affected EGUs in the 48 contiguous States and

148
the District of Columbia (“D.C.”). (42 U.S.C. 7651 et seq.) SO
2
emissions from
numerous States in the eastern half of the United States are also limited under the Cross-
State Air Pollution Rule (“CSAPR”). 76 FR 48208 (Aug. 8, 2011). CSAPR requires
these States to reduce certain emissions, including annual SO
2
emissions, and went into
effect as of January 1, 2015.
96
AEO2023 incorporates implementation of CSAPR,
including the update to the CSAPR ozone season program emission budgets and target
dates issued in 2016. 81 FR 74504 (Oct. 26, 2016). Compliance with CSAPR is flexible
among EGUs and is enforced through the use of tradable emissions allowances. Under
existing EPA regulations, for states subject to SO
2
emissions limits under CSAPR, any
excess SO
2
emissions allowances resulting from the lower electricity demand caused by
the adoption of an efficiency standard could be used to permit offsetting increases in SO
2
emissions by another regulated EGU.
However, beginning in 2016, SO
2
emissions began to fall as a result of the
Mercury and Air Toxics Standards (“MATS”) for power plants. 77 FR 9304 (Feb. 16,
2012). The direct final rule establishes power plant emission standards for mercury, acid
gases, and non-mercury metallic toxic pollutants. In order to continue operating, coal
plants must have either flue gas desulfurization or dry sorbent injection systems installed.
Both technologies, which are used to reduce acid gas emissions, also reduce SO
2
96
CSAPR requires states to address annual emissions of SO
2
and NO
X
, precursors to the formation of fine
particulate matter (“PM
2.5
”) pollution, in order to address the interstate transport of pollution with respect to
the 1997 and 2006 PM
2.5
National Ambient Air Quality Standards (“NAAQS”). CSAPR also requires
certain states to address the ozone season (MaySeptember) emissions of NO
X
, a precursor to the formation
of ozone pollution, in order to address the interstate transport of ozone pollution with respect to the 1997
ozone NAAQS. 76 FR 48208 (Aug. 8, 2011). EPA subsequently issued a supplemental rule that included
an additional five states in the CSAPR ozone season program; 76 FR 80760 (Dec. 27, 2011) (Supplemental
Rule), and EPA issued the CSAPR Update for the 2008 ozone NAAQS. 81 FR 74504 (Oct. 26, 2016).
149
emissions. Because of the emissions reductions under the MATS, it is unlikely that
excess SO
2
emissions allowances resulting from the lower electricity demand would be
needed or used to permit offsetting increases in SO
2
emissions by another regulated EGU.
Therefore, energy conservation standards that decrease electricity generation will
generally reduce SO
2
emissions. DOE estimated SO
2
emissions reduction using
emissions factors based on AEO2023.
CSAPR also established limits on NO
X
emissions for numerous States in the
eastern half of the United States. Energy conservation standards would have little effect
on NO
X
emissions in those States covered by CSAPR emissions limits if excess NO
X
emissions allowances resulting from the lower electricity demand could be used to permit
offsetting increases in NO
X
emissions from other EGUs. In such case, NO
X
emissions
would remain near the limit even if electricity generation goes down. Depending on the
configuration of the power sector in the different regions and the need for allowances,
however, NO
X
emissions might not remain at the limit in the case of lower electricity
demand. That would mean that standards might reduce NO
X
emissions in covered States.
Despite this possibility, DOE has chosen to be conservative in its analysis and has
maintained the assumption that standards will not reduce NO
X
emissions in States
covered by CSAPR. Standards would be expected to reduce NO
X
emissions in the States
not covered by CSAPR. DOE used AEO2023 data to derive NO
X
emissions factors for
the group of States not covered by CSAPR.
The MATS limit mercury emissions from power plants, but they do not include
emissions caps and, as such, DOE’s energy conservation standards would be expected to
150
slightly reduce Hg emissions. DOE estimated mercury emissions reduction using
emissions factors based on AEO2023, which incorporates the MATS.
EEI stated that the emissions estimates are significantly overstated with the
passage of the Inflation Reduction Act (“IRA”). EEI recommended that DOE update the
analysis to account for the IRA and all the impacts in terms of the significantly increased
use of renewable electricity as well as the increase in the number of utilities that have
stated zero carbon electricity can be attained within the next 15 to 25 years. (EEI, No. 37
at pp. 54–55)
As previously stated, for the direct final rule DOE used the AEO2023 Reference
case, which includes the IRA, to represent the electric power sector over the coming
decades. The AEO2023 Reference case reflects EIA’s view of the most likely uptake of
IRA tax credits, and it assumes qualified technologies receive the base tax credit and
some bonus credits. The IRA provisions, in combination with other policies and market
forces, push wind and solar to 56 percent of electricity generation by 2050. DOE
estimated emissions reductions from the adopted standards relative to this case.
L. Monetizing Emissions Impacts
As part of the development of this direct final rule, for the purpose of complying
with the requirements of Executive Order 12866, DOE considered the estimated
monetary benefits from the reduced emissions of CO
2
, CH
4
, N
2
O, NO
X
, and SO
2
that are
expected to result from each of the TSLs considered. In order to make this calculation
analogous to the calculation of the NPV of consumer benefit, DOE considered the
151
reduced emissions expected to result over the lifetime of products shipped in the
projection period for each TSL. This section summarizes the basis for the values used for
monetizing the emissions benefits and presents the values considered in this direct final
rule.
To monetize the benefits of reducing GHG emissions, this analysis uses the
interim estimates presented in the Technical Support Document: Social Cost of Carbon,
Methane, and Nitrous Oxide Interim Estimates Under Executive Order 13990 published
in February 2021 by the IWG.
1. Monetization of Greenhouse Gas Emissions
DOE estimates the monetized benefits of the reductions in emissions of CO
2
,
CH
4
, and N
2
O by using a measure of the SC of each pollutant (e.g., social costs of
greenhouse gases “SC-CO
2
”). These estimates represent the monetary value " of the net
harm to society associated with a marginal increase in emissions of these pollutants in a
given year, or the benefit of avoiding that increase. These estimates are intended to
include (but are not limited to) climate change-related changes in net agricultural
productivity, human health, property damages from increased flood risk, disruption of
energy systems, risk of conflict, environmental migration, and the value of ecosystem
services.
DOE exercises its own judgment in presenting monetized climate benefits as
recommended by applicable Executive orders, and DOE would reach the same
conclusion presented in this rulemaking in the absence of the social cost of greenhouse
152
gases. That is, the SC-CO
2
, whether measured using the February 2021 interim estimates
presented by the Interagency Working Group on the Social Cost of Greenhouse Gases or
by another means, did not affect the rule ultimately proposed by DOE.
DOE estimated the global social benefits of CO
2
, CH
4
, and N
2
O reductions using
SC-GHG values that were based on the interim values presented in the Technical Support
Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates under
Executive Order 13990, published in February 2021 by the IWG. The SC-GHG is the
monetary value of the net harm to society associated with a marginal increase in
emissions in a given year, or the benefit of avoiding that increase. In principle, the SC-
GHG includes the value of all climate change impacts, including (but not limited to)
changes in net agricultural productivity, human health effects, property damage from
increased flood risk and natural disasters, disruption of energy systems, risk of conflict,
environmental migration, and the value of ecosystem services. The SC-GHG therefore
reflects the societal value of reducing emissions of the gas in question by one metric ton.
The SC-GHG is the theoretically appropriate value to use in conducting benefit-cost
analyses of policies that affect CO
2
, N
2
O, and CH
4
emissions. As a member of the IWG
involved in the development of the February 2021 SC-GHG TSD, DOE agrees that the
interim SC-GHG estimates represent the most appropriate estimate of the SC-GHG for
this rule, which was developed using the interim estimates. DOE continues to evaluate
recent developments in the scientific literature, including the updated SC-GHG estimates
published by the EPA in December 2023 within their rulemaking on oil and natural gas
153
sector sources.
97
For this rulemaking, DOE used these updated SC-GHG values to
conduct a sensitivity analysis of the value of GHG emissions reductions associated with
alternative standards for clothes dryers (see section IV.L.1.c of this document).
The SC-GHG estimates presented here were developed over many years, using
peer-reviewed methodologies, a transparent process, the best science available at the time
of that process, and input from the public. Specifically, in 2009, the IWG, which included
DOE and other executive branch agencies and offices, was established to ensure that
agencies were using the best available science and to promote consistency in the SC-CO
2
values used across agencies. The IWG published SC-CO
2
estimates in 2010 that were
developed from an ensemble of three widely cited integrated assessment models
(“IAMs”) that estimate global climate damages using highly aggregated representations
of climate processes and the global economy combined into a single modeling
framework. The three IAMs were run using a common set of input assumptions in each
model for future population, economic, and CO
2
emissions growth, as well as equilibrium
climate sensitivitya measure of the globally averaged temperature response to
increased atmospheric CO
2
concentrations. These estimates were updated in 2013 based
on new versions of each IAM. In August 2016 the IWG published estimates of the social
cost of methane (“SC-CH
4
”) and nitrous oxide (“SC-N
2
O”) using methodologies that are
consistent with the methodology underlying the SC-CO
2
estimates. The modeling
approach that extends the IWG SC-CO
2
methodology to non-CO
2
GHGs has undergone

154
multiple stages of peer review. The SC-CH
4
and SC-N
2
O estimates were developed by
Marten et al.
98
and underwent a standard double-blind peer review process prior to
journal publication. In 2015, as part of the response to public comments received
following a 2013 solicitation for comments on the SC-CO
2
estimates, the IWG
announced a National Academies of Sciences, Engineering, and Medicine review of the
SC-CO
2
estimates to offer advice on how to approach future updates to ensure that the
estimates continue to reflect the best available science and methodologies. In January
2017, the National Academies released their final report, Valuing Climate Damages:
Updating Estimation of the Social Cost of Carbon Dioxide, and recommended specific
criteria for future updates to the SC-CO
2
estimates, a modeling framework to satisfy the
specified criteria, and both near-term updates and longer-term research needs pertaining
to various components of the estimation process (National Academies, 2017).
99
Shortly
thereafter, in March 2017, President Trump issued Executive Order (“E.O.”) 13783,
which disbanded the IWG, withdrew the previous TSDs, and directed agencies to ensure
SC-CO
2
estimates used in regulatory analyses are consistent with the guidance contained
in OMB’s Circular A-4
100
, “including with respect to the consideration of domestic
versus international impacts and the consideration of appropriate discount rates” (E.O.
13783, Section 5(c)). Benefit-cost analyses following E.O. 13783 used SC-GHG
estimates that attempted to focus on the U.S.-specific share of climate change damages as

estimated by the models and were calculated using two discount rates recommended by
Circular A-4, 3 percent and 7 percent. All other methodological decisions and model
versions used in SC-GHG calculations remained the same as those used by the IWG in
2010 and 2013, respectively.
On January 20, 2021, President Biden issued Executive Order 13990, which re-
established the IWG and directed it to ensure that the U.S. Government’s estimates of the
social cost of carbon and other greenhouse gases reflect the best available science and the
recommendations of the National Academies (2017). The IWG was tasked with first
reviewing the SC-GHG estimates currently used in Federal analyses and publishing
interim estimates within 30 days of E.O. 13990 that reflect the full impact of GHG
emissions, including by taking global damages into account. The interim SC-GHG
estimates published in February 2021 are used here to estimate the climate benefits for
this rulemaking. E.O. 13990 instructs the IWG to undertake a fuller update of the SC-
GHG estimates by January 2022 that takes into consideration the advice of the National
Academies (2017) and other recent scientific literature. The February 2021 SC-GHG
TSD provides a complete discussion of the IWG’s initial review conducted under E.O.
13990. In particular, the IWG found that the SC-GHG estimates used under E.O. 13783
fail to reflect the full impact of GHG emissions in multiple ways.
First, the IWG found that the SC-GHG estimates used under E.O. 13783 fail to
fully capture many climate impacts that affect the welfare of U.S. citizens and residents,
and those impacts are better reflected by global measures of the SC-GHG. Examples of
omitted effects from the E.O. 13783 estimates include direct effects on U.S. citizens,
156
assets, and investments located abroad; supply chains, U.S. military assets and interests
abroad, and tourism; and spillover pathways such as economic and political
destabilization and global migration that can lead to adverse impacts on U.S. national
security, public health, and humanitarian concerns. In addition, assessing the benefits of
United States GHG mitigation activities requires consideration of how those actions may
affect mitigation activities by other countries, as those international mitigation actions
will provide a benefit to United States citizens and residents by mitigating climate
impacts that affect United States citizens and residents. A wide range of scientific and
economic experts have emphasized the issue of reciprocity as support for considering
global damages of GHG emissions. If the United States does not consider impacts on
other countries, it is difficult to convince other countries to consider the impacts of their
emissions on the United States. The only way to achieve an efficient allocation of
resources for emissions reduction on a global basis—and so benefit the United States and
its citizensis for all countries to base their policies on global estimates of damages. As
a member of the IWG involved in the development of the February 2021 SC-GHG TSD,
DOE agrees with this assessment and, therefore, in this direct final rule DOE centers
attention on a global measure of SC-GHG. This approach is the same as that taken in
DOE regulatory analyses from 2012 through 2016. A robust estimate of climate damages
that accrue only to U.S. citizens and residents does not currently exist in the literature. As
explained in the February 2021 TSD, existing estimates are both incomplete and an
underestimate of total damages that accrue to the citizens and residents of the U.S.
because they do not fully capture the regional interactions and spillovers previously
discussed, nor do they include all of the important physical, ecological, and economic
157
impacts of climate change recognized in the climate change literature. As noted in the
February 2021 SC-GHG TSD, the IWG will continue to review developments in the
literature, including more robust methodologies for estimating a U.S.-specific SC-GHG
value, and explore ways to better inform the public of the full range of carbon impacts.
As a member of the IWG, DOE will continue to follow developments in the literature
pertaining to this issue.
Second, the IWG found that the use of the social rate of return on capital (7
percent under current OMB Circular A-4 guidance) to discount the future benefits of
reducing GHG emissions inappropriately underestimates the impacts of climate change
for the purposes of estimating the SC-GHG. Consistent with the findings of the National
Academies (2017) and the economic literature, the IWG continued to conclude that the
consumption rate of interest is the theoretically appropriate discount rate in an
intergenerational context
101
and recommended that discount rate uncertainty and relevant

aspects of intergenerational ethical considerations be accounted for in selecting future
discount rates.
Furthermore, the damage estimates developed for use in the SC-GHG are
estimated in consumption-equivalent terms, and so an application of OMB Circular A-4's
guidance for regulatory analysis would then use the consumption discount rate to
calculate the SC-GHG. DOE agrees with this assessment and will continue to follow
developments in the literature pertaining to this issue. DOE also notes that while OMB
Circular A-4, as published in 2003, recommends using 3-percent and 7-percent discount
rates as “default” values, Circular A-4 also reminds agencies that “different regulations
may call for different emphases in the analysis, depending on the nature and complexity
of the regulatory issues and the sensitivity of the benefit and cost estimates to the key
assumptions.” On discounting, Circular A-4 recognizes that “special ethical
considerations arise when comparing benefits and costs across generations,” and Circular
A-4 acknowledges that analyses may appropriately “discount future costs and
consumption benefits…at a lower rate than for intragenerational analysis.” In the 2015
Response to Comments on the Social Cost of Carbon for Regulatory Impact Analysis,
OMB, DOE, and the IWG members recognized that "Circular A-4 is a living document"
and “the use of 7 percent is not considered appropriate for intergenerational discounting.
There is wide support for this view in the academic literature, and it is recognized in
Circular A-4 itself.” Thus, DOE concludes that a 7-percent discount rate is not
appropriate to apply to value the social cost of greenhouse gases in the analysis presented
in this document.
159
To calculate the present and annualized values of climate benefits, DOE uses the
same discount rate as the rate used to discount the value of damages from future GHG
emissions for internal consistency. That approach to discounting follows the same
approach that the February 2021 TSD recommends "to ensure internal consistency—i.e.,
future damages from climate change using the SC-GHG at 2.5 percent should be
discounted to the base year of the analysis using the same 2.5 percent rate.” DOE has also
consulted the National Academies’ 2017 recommendations on how SC-GHG estimates
can “be combined in RIAs with other cost and benefits estimates that may use different
discount rates.” The National Academies reviewed several options, including “presenting
all discount rate combinations of other costs and benefits with [SC-GHG] estimates.”
As a member of the IWG involved in the development of the February 2021 SC-
GHG TSD, DOE agrees with the above assessment and will continue to follow
developments in the literature pertaining to this issue. While the IWG works to assess
how best to incorporate the latest, peer-reviewed science to develop an updated set of SC-
GHG estimates, it set the interim estimates to be the most recent estimates developed by
the IWG prior to the group being disbanded in 2017. The estimates rely on the same
models and harmonized inputs and are calculated using a range of discount rates. As
explained in the February 2021 SC-GHG TSD, the IWG has recommended that agencies
revert to the same set of four values drawn from the SC-GHG distributions based on three
discount rates as were used in regulatory analyses between 2010 and 2016 and were
subject to public comment. For each discount rate, the IWG combined the distributions
across models and socioeconomic emissions scenarios (applying equal weight to each)
and then selected a set of four values recommended for use in benefit-cost analyses: an
160
average value resulting from the model runs for each of three discount rates (2.5 percent,
3 percent, and 5 percent) plus a fourth value, selected as the 95th percentile of estimates
based on a 3-percent discount rate. The fourth value was included to provide information
on potentially higher-than-expected economic impacts from climate change. As explained
in the February 2021 SC-GHG TSD, with which DOE agrees, this update reflects the
immediate need to have an operational SC-GHG for use in regulatory benefit-cost
analyses and other applications that was developed using a transparent process, peer-
reviewed methodologies, and the science available at the time of that process. Those
estimates were subject to public comment in dozens of proposed rulemakings as well as
in a dedicated public comment period in 2013.
There are a number of limitations and uncertainties associated with the SC-GHG
estimates. First, the current scientific and economic understanding of discounting
approaches suggests discount rates appropriate for intergenerational analysis in the
context of climate change are likely to be less than 3 percent, near 2 percent, or lower.
102
Second, the IAMs used to produce these interim estimates do not include all of the
important physical, ecological, and economic impacts of climate change recognized in
the climate change literature, and the science underlying their “damage functions”—i.e.,
the core parts of the IAMs that map global mean temperature changes and other physical
impacts of climate change into economic (both market and nonmarket) damageslags
behind the most recent research. For example, limitations include the incomplete

161
treatment of catastrophic and non-catastrophic impacts in the integrated assessment
models, their incomplete treatment of adaptation and technological change, the
incomplete way in which interregional and intersectoral linkages are modeled,
uncertainty in the extrapolation of damages to high temperatures, and inadequate
representation of the relationship between the discount rate and uncertainty in economic
growth over long time horizons. Likewise, the socioeconomic and emissions scenarios
used as inputs to the models do not reflect new information from the last decade of
scenario generation or the full range of projections. The modeling limitations do not all
work in the same direction in terms of their influence on the SC-CO
2
estimates. However,
as discussed in the February 2021 TSD, the IWG has recommended that, taken together,
the limitations suggest that the interim SC-GHG estimates used in this direct final rule
likely underestimate the damages from GHG emissions. DOE concurs with this
assessment.
DOE's derivations of the SC-CO
2
, SC-N
2
O, and SC-CH
4
values used for this
direct final rule are discussed in the following sections, and the results of DOE's analyses
estimating the benefits of the reductions in emissions of these GHGs are presented in
section V.B.6 of this document.
a. Social Cost of Carbon
The SC-CO
2
values used for this direct final rule were based on the values
developed for the IWG’s February 2021 TSD, which are shown in Table IV.22 in 5-year
increments from 2020 to 2050. The set of annual values that DOE used, which was
162
adapted from estimates published by EPA,
103
is presented in appendix 14A of the direct
final rule TSD. These estimates are based on methods, assumptions, and parameters
identical with the 2020–2050 estimates published by the IWG (which were based on EPA
modeling) and include values for 2051 to 2070. DOE expects additional climate benefits
to accrue for any longer-life consumer clothes dryers after 2070, but a lack of available
SC-CO
2
estimates for emissions years beyond 2070 prevents DOE from monetizing these
potential benefits in this analysis.
For purposes of capturing the uncertainties involved in regulatory impact analysis,
DOE has determined it is appropriate to include all four sets of SC-CO
2
values, as
recommended by the IWG.

For example, the February 2021 TSD discusses how the understanding of discounting approaches
suggests that discount rates appropriate for intergenerational analysis in the context of climate change may
be lower than 3 percent.
163
DOE multiplied the CO
2
emissions reduction estimated for each year by the SC-
CO
2
value for that year in each of the four cases. DOE adjusted the values to 2022$
using the implicit price deflator for gross domestic product (“GDP”) from the Bureau of
Economic Analysis. To calculate a present value of the stream of monetary values, DOE
discounted the values in each of the four cases using the specific discount rate that had
been used to obtain the SC-CO
2
values in each case.
b. Social Cost of Methane and Nitrous Oxide
The SC-CH

and SC-N
2
O values used for this direct final rule were based on the
values developed for the February 2021 TSD. Table IV.23 shows the updated sets of SC-

and SC-N
2
O estimates from the latest interagency update in 5-year increments from
2020 to 2050. The full set of annual values used is presented in appendix 14A of the
direct final rule TSD. To capture the uncertainties involved in regulatory impact
analysis, DOE has determined it is appropriate to include all four sets of SC-CH
4
and SC-
N
2
O values, as recommended by the IWG. DOE derived values after 2050 using the
approach described above for the SC-CO

c. Sensitivity Analysis Using Updated 2023 SC-GHG Estimates
In December 2023 EPA issued a new set of SC-GHG estimates (2023 SC-GHG)
in connection with a final rulemaking under the Clean Air Act.
105
For this rulemaking,
DOE used these updated 2023 SC-GHG values to conduct a sensitivity analysis of the
value of GHG emissions reductions associated with alternative standards for consumer
clothes dryers. This sensitivity analysis provides an expanded range of potential climate
benefits associated with amended standards. The final year of EPA’s new the 2023 SC-
GHG estimates is 2080; therefore, DOE did not monetize the climate benefits of GHG
emissions reductions occurring after 2080.
The overall climate benefits are larger using when using the higher, updated 2023
SC-GHG estimates, compared to the climate benefits using the older IWG SC-GHG
estimates. However, DOE’s conclusion that the standards are economically justified
remains the same regardless of which SC-GHG estimates are used.
105
See www.epa.gov/environmental-economics/scghg.
165
The results of the sensitivity analysis are presented in appendix 14C of the direct
final rule TSD.
2. Monetization of Other Emissions Impacts
For the direct final rule, DOE estimated the monetized value of NO
X
and SO
2
emissions reductions from electricity generation using benefit-per-ton estimates for that
sector from the EPA’s Benefits Mapping and Analysis Program.
106
DOE used EPA’s
values for PM
2.5
-related benefits associated with NO
X
and SO
2
and for ozone-related
benefits associated with NO
X
for 2025 and 2030, and 2040, calculated with discount rates
of 3 percent and 7 percent. DOE used linear interpolation to define values for the years
not given in the 2025 to 2040 period; for years beyond 2040, the values are held constant.
DOE combined the EPA benefit-per-ton estimates with regional information on
electricity consumption and emissions to define weighted average national values for
NO
X
and SO
2
as a function of sector (see appendix 14B of the direct final rule TSD).
DOE also estimated the monetized value of NO
X
and SO

buildings.
107
The EPA document provides high and low estimates for 2025 and 2030 at
3- and 7-percent discount rates.
108
DOE used the same linear interpolation and
extrapolation as it did with the values for electricity generation.
DOE multiplied the site emissions reduction (in tons) in each year by the
associated $/ton values, and then discounted each series using discount rates of 3 percent
and 7 percent as appropriate.
For this direct final rule, DOE considered comments it had received regarding its
monetization emission impact analysis presented in the August 2022 NOPR. The
approach used for this direct final rule is largely the same as the approach DOE had used
for the August 2022 NOPR analysis.
In response to the August 2022 NOPR, AHAM disagreed with DOE’s use of both
the social cost of carbon (“SCC”) and other monetization of emissions reductions benefits
in its analysis of the factors that EPCA requires DOE to balance in determining the
appropriate standard, as these values are highly subjective and ever-changing. (AHAM,
No. 46 at p. 14)
As stated in section III.E.1.f of this document, DOE maintains that environmental
and public health benefits associated with more efficient use of energy, including those

“Area sources” represents all emission sources for which states do not have exact (point) locations in
their emissions inventories. Because exact locations would tend to be associated with larger sources, “area
sources” would be fairly representative of small, dispersed sources like homes and businesses.
108
“Area sources” are a category in the 2018 document from EPA but are not used in the 2021 document
cited above. See www.epa.gov/sites/default/files/2018-02/documents/sourceapportionmentbpttsd_2018.pdf.

connected to global climate change, are important to take into account when considering
the need for national energy conservation, which is one of the factors that EPCA requires
DOE to evaluate in determining whether a potential energy conservation standard is
economically justified. In addition, Executive Order 13563, which was reaffirmed on
January 21, 2021, stated that each agency must, among other things, “select, in choosing
among alternative regulatory approaches, those approaches that maximize net benefits
(including potential economic, environmental, public health and safety, and other
advantages; distributive impacts; and equity).” For these reasons, DOE includes
monetized emissions reductions in its evaluation of potential standard levels. As
previously stated, however, DOE would reach the same conclusion presented in this
rulemaking in the absence of the SC-GHG. At the Recommended TSL, the average LCC
savings for all product classes is positive. In addition, the FFC national energy savings
are significant and the NPV of consumer benefits is positive using both a 3-percent and
7-percent discount rate. Even when measured at the more conservative discount rate of 7
percent, the NPV of consumer benefits is over 64 times higher than the maximum
estimated manufacturers’ loss in INPV.
M. Utility Impact Analysis
The utility impact analysis estimates the changes in installed electrical capacity
and generation projected to result for each considered TSL. The analysis is based on
published output from the NEMS associated with AEO2023. NEMS produces the AEO
Reference case, as well as a number of side cases that estimate the economy-wide
impacts of changes to energy supply and demand. For the current analysis, impacts are
quantified by comparing the levels of electricity sector generation, installed capacity, fuel
168
consumption, and emissions in the AEO2023 Reference case and various side cases.
Details of the methodology are provided in the appendices to chapters 13 and 15 of the
direct final rule TSD.
The output of this analysis is a set of time-dependent coefficients that capture the
change in electricity generation, primary fuel consumption, installed capacity and power
sector emissions due to a unit reduction in demand for a given end use. These
coefficients are multiplied by the stream of electricity savings calculated in the NIA to
provide estimates of selected utility impacts of potential new or amended energy
conservation standards.
The utility analysis also estimates the impact on gas utilities in terms of projected
changes in natural gas deliveries to consumers for each TSL.
N. Employment Impact Analysis
DOE considers employment impacts in the domestic economy as one factor in
selecting a standard. Employment impacts from new or amended energy conservation
standards include both direct and indirect impacts. Direct employment impacts are any
changes in the number of employees of manufacturers of the products subject to
standards, their suppliers, and related service firms. The MIA addresses those impacts.
Indirect employment impacts are changes in national employment that occur due to the
shift in expenditures and capital investment caused by the purchase and operation of
more efficient appliances. Indirect employment impacts from standards consist of the net
jobs created or eliminated in the national economy, other than in the manufacturing sector
169
being regulated, caused by (1) reduced spending by consumers on energy, (2) reduced
spending on new energy supply by the utility industry, (3) increased consumer spending
on the products to which the new standards apply and other goods and services, and (4)
the effects of those three factors throughout the economy.
One method for assessing the possible effects on the demand for labor of such
shifts in economic activity is to compare sector employment statistics developed by the
Labor Department’s Bureau of Labor Statistics (“BLS”). BLS regularly publishes its
estimates of the number of jobs per million dollars of economic activity in different
sectors of the economy, as well as the jobs created elsewhere in the economy by this
same economic activity. Data from BLS indicate that expenditures in the utility sector
generally create fewer jobs (both directly and indirectly) than expenditures in other
sectors of the economy.
109
There are many reasons for these differences, including wage
differences and the fact that the utility sector is more capital-intensive and less labor-
intensive than other sectors. Energy conservation standards have the effect of reducing
consumer utility bills. Because reduced consumer expenditures for energy likely lead to
increased expenditures in other sectors of the economy, the general effect of efficiency
standards is to shift economic activity from a less labor-intensive sector (i.e., the utility
sector) to more labor-intensive sectors (e.g., the retail and service sectors). Thus, the

Office: Washington, DC. Available at www.osti.gov/biblio/7281092 (last accessed July 1, 2021).
170
BLS data suggest that net national employment may increase due to shifts in economic
activity resulting from energy conservation standards.
DOE estimated indirect national employment impacts for the standard levels
considered in this direct final rule using an input/output model of the U.S. economy
called Impact of Sector Energy Technologies version 4 (“ImSET”).
110
ImSET is a
special-purpose version of the “U.S. Benchmark National Input-Output” (“I-O”) model,
which was designed to estimate the national employment and income effects of energy-
saving technologies. The ImSET software includes a computer-based I-O model having
structural coefficients that characterize economic flows among 187 sectors most relevant
to industrial, commercial, and residential building energy use.
DOE notes that ImSET is not a general equilibrium forecasting model, and that
the uncertainties involved in projecting employment impacts, especially changes in the
later years of the analysis. Because ImSET does not incorporate price changes, the
employment effects predicted by ImSET may overestimate actual job impacts over the
long run for this rule. Therefore, DOE used ImSET only to generate results for near-term
timeframes (20272033) where these uncertainties are reduced.
111

the employment impact analysis, see chapter 16 of the direct final rule TSD.

O. Regulatory Impact Analysis
For any regulatory action that the Administrator of the Office of Information and
Regulatory Affairs (“OIRA”) within OMB determines is a significant regulatory action
under section 3(f)(1) of E.O. 12866, section 6(a)(3)(C) of E.O. 12866 requires Federal
agencies to provide an assessment, including the underlying analysis, of costs and
benefits of potentially effective and reasonably feasible alternatives to the planned
regulation, identified by the agencies or the public (including improving the current
regulation and reasonably viable non-regulatory actions), and an explanation why the
planned regulatory action is preferable to the identified potential alternatives. 58 FR
51735, 51741. As discussed further in section VI.A of this document, OIRA has
determined that this final regulatory action constitutes a “significant regulatory action”
within the scope of section 3(f)(1) of E.O. 12866, as amended by E.O. 14094.
Accordingly, DOE conducted a regulatory impact analysis (“RIA”) for this direct final
rule.
As part of the RIA, DOE identifies major alternatives to standards that represent
feasible policy options to reduce the energy and water consumption of the covered
product. DOE evaluates each alternative in terms of its ability to achieve significant
energy and water savings at a reasonable cost, and compares the effectiveness of each
alternative to the effectiveness of the finalized standard. DOE recognizes that voluntary
or other non-regulatory efforts by manufacturers, utilities, and other interested parties can
substantially affect energy and water efficiency or reduce energy and water consumption.
DOE bases its assessment on the recorded impacts of any such initiatives to date, but also
considers information presented by interested parties regarding the impacts current
172
initiatives may have in the future. Further details regarding the RIA are provided in
chapter 17 of the direct final rule TSD.
P. Other Comments
As discussed previously, DOE considered relevant comments, data, and
information obtained during its own rulemaking process in determining whether the
recommended standards from the Joint Agreement are in accordance with 42 U.S.C.
6295(o). And while some of those comments were directed at specific aspects of DOE’s
analysis of the Joint Agreement under 42 U.S.C. 6295(o), others were more generally
applicable to DOE’s energy conservation standards rulemaking program as a whole. The
ensuing discussion focuses on these general comments concerning energy conservation
standards issued under EPCA.
The National Academies of Sciences, Engineering, and Medicine (“NAS”)
periodically appoint a committee to peer review the assumptions, models, and
methodologies that DOE uses in setting energy conservation standards for covered
products and equipment. The most recent such peer review was conducted in a series of
meetings in 2020, and NAS issued the report
112
in 2021 detailing its findings and
recommendations on how DOE can improve its analyses and align them with best
practices for cost-benefit analysis.
112
Review of Methods Used by the U.S. Department of Energy in Setting Appliance and Equipment
Standards (2021), available at nap.nationalacademies.org/25992.
173
AHAM recommended that DOE adopt the recommendations of the NAS report
and incorporate the Regulatory Impact Analysis methodology of Office of Management
and Budget (“OMB”) Circular A-4 and start with a more robust assessment of private
market failures and alternatives to minimum standards that includes a robust
identification and assessment of market failures by market segment. (AHAM, No. 46 at
pp. 12–13)
AGA and APGA also commented that DOE should implement recommendations
in the NAS report, specifically: appliance standards should be economically justified or
based on significant failures of private markets or irrational consumer behavior
(Recommendation 2-2); the Cost Analysis segment of the Engineering Analysis should
be expanded to include ranges of costs, patterns of consumption, diversity factors, energy
peak demand, and variance regarding environmental factors (Recommendation 3-5);
DOE should put greater weight on ex post and market-based evidence of markups to
project a more realistic range of effects of a standard on prices (Recommendation 4-1);
DOE should place greater emphasis on providing an argument for the plausibility and
magnitude of any market failure related to the energy efficiency gap in its analyses
(Recommendation 4-13); and DOE should give greater attention to a broader set of
potential market failures on the supply side, including how standards might reduce the
number of competing firms, and also how standards might impact price discrimination,
technological diffusion, and collusion (Recommendation 4-14). (APGA et al., No. 47 at
pp. 2–3)
174
The rulemaking process for standards of covered products and equipment are
outlined at appendix A to subpart C of 10 CFR part 430, and DOE periodically examines
and revises these provisions in separate rulemaking proceedings. The recommendations
in the NAS report cited by commenters on the August 2022 NOPR, which pertain to the
processes by which DOE analyzes energy conservation standards, will be considered in a
separate rulemaking considering all product categories.
V. Analytical Results and Conclusions
The following section addresses the results from DOE’s analyses with respect to
the considered energy conservation standards for consumer clothes dryers. It addresses
the TSLs examined by DOE, the projected impacts of each of these levels if adopted as
energy conservation standards for consumer clothes dryers, and the standards levels that
DOE is adopting in this direct final rule. Additional details regarding DOE’s analyses are
contained in the direct final rule TSD supporting this document.
A. Trial Standard Levels
In general, DOE typically evaluates potential amended standards for products and
equipment by grouping individual efficiency levels for each class into TSLs. Use of
TSLs allows DOE to identify and consider manufacturer cost interactions between the
product classes, to the extent that there are such interactions, and market cross elasticity
from consumer purchasing decisions that may change when different standard levels are
set.
175
In the analysis conducted for this direct final rule, DOE analyzed the benefits and
burdens of six TSLs for consumer clothes dryers. DOE developed TSLs that combine
efficiency levels for each analyzed product class/category using similar technologies
and/or efficiencies and having roughly comparable equipment availability. DOE presents
the results for the TSLs in this document, while the results for all efficiency levels that
DOE analyzed are in the direct final rule TSD. DOE presents the results for the TSLs in
this document, while the results for all efficiency levels that DOE analyzed are in the
direct final rule TSD.
Table V.1 presents the TSLs and the corresponding efficiency levels that DOE
has identified for potential amended energy conservation standards for consumer clothes
dryers. For the vented gas compact product class, all TSLs represent the baseline
efficiency level because there are no higher efficiency levels, and this level corresponds
to the efficiency level for vented gas compact clothes dryers in the Recommended TSL in
the Joint Agreement. For all remaining product classes, the TSLs are defined as follows.
TSL 6 represents the maximum technologically feasible (“max-tech”) energy efficiency.
TSL 5 represents the maximum national energy savings with maximum positive NPV.
TSL 4 represents the maximum national energy savings with simple PBP less than 4
years. TSL 3—which corresponds to the Recommended TSL in the Joint Agreement—
represents the intermediate efficiency level between TSL 2 and TSL 4. TSL 2
corresponds to the efficiency level with high-speed spin for ventless electric combination
washer-dryer and automatic termination control system for all other product classes. TSL
1 corresponds to the efficiency level with electronic controls.

DOE constructed the TSLs for this direct final rule to include efficiency levels
(“ELs”) representative of ELs with similar characteristics (i.e., using similar technologies
and/or efficiencies, and having roughly comparable equipment availability). The use of
representative ELs provided for greater distinction between the TSLs. While
representative ELs were included in the TSLs, DOE considered all ELs as part of its
analysis but did not include all ELs in the TSLs.
113
113
Efficiency levels that were analyzed for this final rule are discussed in section IV.C.1 of this document.
Results by efficiency level are presented in the final rule TSD chapters 8 and 10.
177
B. Economic Justification and Energy Savings
1. Economic Impacts on Individual Consumers
DOE analyzed the economic impacts on consumers of consumer clothes dryers by
looking at the effects that potential amended standards at each TSL would have on the
LCC and PBP. DOE also examined the impacts of potential standards on selected
consumer subgroups. These analyses are discussed in the following sections.
a. Life-Cycle Cost and Payback Period
In general, higher efficiency products affect consumers in two ways: (1) purchase
price increases and (2) annual operating costs decrease. Inputs used for calculating the
LCC and PBP include total installed costs (i.e., product price plus installation costs) and
operating costs (i.e., annual energy use, energy prices, energy price trends, repair costs,
and maintenance costs). The LCC calculation also uses product lifetime and a discount
rate. Chapter 8 of the direct final rule TSD provides detailed information on the LCC and
PBP analyses.
Table V.2 through Table V.13 show the LCC and PBP results for the TSLs
considered for each product class. In the first of each pair of tables, the simple payback
is measured relative to the baseline product. In the second table, the impacts are
measured relative to the efficiency distribution in the in the no-new-standards case in the
compliance year (see section IV.F.8 of this document). Because some consumers
purchase products with higher efficiency in the no-new-standards case, the average
savings are less than the difference between the average LCC of the baseline product and
the average LCC at each TSL. The savings refer only to consumers who are affected by a
178
standard at a given TSL. Those who already purchase a product with efficiency at or
above a given TSL are not affected. Consumers for whom the LCC increases at a given
TSL experience a net cost.

b. Consumer Subgroup Analysis
In the consumer subgroup analysis, DOE estimated the impact of the considered
TSLs on low-income households and senior-only households. Table V.14 through Table
V.25 compare the average LCC savings, PBP, percent of consumers negatively impacted,
and percent of consumers positively impacted at each EL for the consumer subgroups,
along with corresponding values for the entire residential consumer sample for product
classes with a sufficient sample size. In most cases, the average LCC savings and PBP
for low-income households and senior-only households at the considered ELs are not
substantially different from the average for all households. Chapter 11 of the direct final
rule TSD presents the complete LCC and PBP results for the subgroups.

c. Rebuttable Presumption Payback
As discussed in section II.A of this document, EPCA establishes a rebuttable
presumption that an energy conservation standard is economically justified if the
increased purchase cost for a product that meets the standard is less than three times the
value of the first-year energy savings resulting from the standard. In calculating a
rebuttable presumption payback period for each of the considered TSLs, DOE used
discrete values, and, as required by EPCA, based the energy use calculation on the DOE
test procedures for consumer clothes dryers. In contrast, the PBPs presented in section
V.B.1.a of this document were calculated using distributions that reflect the range of
energy use in the field.
Table V.26 presents the rebuttable presumption payback periods for the
considered TSLs for consumer clothes dryers. While DOE examined the rebuttable
presumption criterion, it considered whether the standard levels considered for this rule
are economically justified through a more detailed analysis of the economic impacts of
those levels, pursuant to 42 U.S.C. 6295(o)(2)(B)(i), that considers the full range of
impacts to the consumer, manufacturer, Nation, and environment. The results of that
analysis serve as the basis for DOE to definitively evaluate the economic justification for
a potential standard level, thereby supporting or rebutting the results of any preliminary
determination of economic justification.

2. Economic Impacts on Manufacturers
DOE performed an MIA to estimate the impact of amended energy conservation
standards on manufacturers of consumer clothes dryers. The next section describes the
expected impacts on manufacturers at each considered TSL. Chapter 12 of the direct
final rule TSD explains the analysis in further detail.
a. Industry Cash Flow Analysis Results
In this section, DOE provides GRIM results from the analysis, which examines
changes in the industry that would result from a standard. The following tables
summarize the estimated financial impacts (represented by changes in INPV) of potential
amended energy conservation standards on manufacturers of consumer clothes dryers, as
well as the conversion costs that DOE estimates manufacturers of consumer clothes
dryers would incur at each TSL.
The impacts of potential amended energy conservation standards were analyzed
under two scenarios: (1) the preservation of gross margin percentage; and (2) the
189
preservation of operating profit as discussed in section IV.J.2.d of this document. In the
preservation-of-gross-margin-percentage scenario, DOE applied a gross margin
percentage of 21 percent for all product classes and all efficiency levels in the standards
case.
114
This scenario assumes that a manufacturer’s per-unit dollar profit would increase
as MPCs increase in the standards cases. DOE models this scenario as an upper bound to
industry profitability under an energy conservation standard.
In the preservation-of-operating-profit scenario, manufacturers do not earn
additional operating profit when compared to the no-new-standards case scenario. While
manufacturers make the necessary upfront investments required to produce compliant
products, per-unit operating profit does not change in absolute dollars. DOE models this
scenario as the lower bound to industry profitability under an energy conservation
standard.
Each of the modeled scenarios results in a unique set of cash flows and
corresponding INPV for each TSL. INPV is the sum of the discounted cash flows to the
industry from the base year through the end of the analysis period (30 years from the
analyzed compliance year).
115
The “change in INPV” results refer to the difference in
industry value between the no-new-standards case and standards case at each TSL. To
provide perspective on the short-run cash-flow impact, DOE includes a comparison of
free cash flow between the no-new-standards case and the standards case at each TSL in
114
The gross margin percentage of 21 percent is based on a manufacturer markup of 1.26.
115
The analysis period ranges from 20242056 for the no-new-standards case and all TSLs, except for TSL
3 (the Recommended TSL). The analysis period for TSL 3 ranges from 20242057 due to the 2028
compliance year.
190
the year before amended standards would take effect. This figure provides an
understanding of the magnitude of the required conversion costs relative to the cash flow
generated by the industry in the no-new-standards case.
Conversion costs are one-time investments for manufacturers to bring their
manufacturing facilities and product designs into compliance with potential amended
standards. As described in section IV.J.2.c of this document, conversion cost investments
occur between the year of publication of the direct final rule and the year by which
manufacturers must comply with the new standard. The conversion costs can have a
significant impact on short-term cash flow within the industry and generally result in
lower free cash flow in the period between publication of the direct final rule and the
compliance date of potential amended standards. Conversion costs are independent of the
manufacturer markup scenarios and are not presented as a range in this analysis.

**TSL 3 (the Recommended TSL) represents the change in free cash flow in 2027, a year before the 2028
compliance date.
*** In 2027, the no-new-standards free cash flow is $136.6 million.
The cash flow results discussion below refers to product classes as defined in
Table IV.1 in section IV.A.1 of this document. It also refers to the efficiency levels and
associated design options designated in Table IV.5 through Table IV.10 in section
IV.C.1.b of this document.
At TSL 1, the standard reflects efficiency levels with electronic controls for all
product classes. The change in INPV is expected to range from -1.7 to -1.5 percent. At
this level, free cash flow is estimated to decrease by 12.8 percent compared to the no-
new-standards case value of $136.7 million in the year 2026, the year before the 2027
standards year. DOE’s shipments analysis estimates approximately 85 percent of current
shipments meet this level.
116
The design options DOE analyzed include implementing electronic controls. For
electric standard, electric compact (120V), vented electric compact (240V), and vented
gas standard, TSL 1 corresponds to EL 1. For ventless electric compact (240V) and
ventless electric combination washer-dryer, TSL 1 corresponds to the baseline CEF
D2
.
Capital conversion costs may be necessary for additional tooling for timers and
electronics. Product conversion costs may be necessary for developing, sourcing, and
testing electronics (e.g., safety, performance, and durability tests). DOE does not expect
industry to incur re-flooring costs at this level since the necessary enhancements could be

192
done “behind the hinge,” incorporating the design changes in a manner that does not
impact product appearance. DOE does not expect industry to incur conversion costs
related to the ventless electric compact (240V) or ventless electric combination washer-
dryer as the efficiency levels would remain at baseline. DOE estimates capital conversion
costs of $18.6 million and product conversion costs of $27.3 million. Conversion costs
total $45.8 million.
At TSL 1, the shipment-weighted average MPC for all consumer clothes dryers is
expected to increase by 0.3 percent relative to the no-new-standards case shipment-
weighted average MPC for all consumer clothes dryers in 2027. Given this relatively
small increase in production costs, DOE does not project a notable drop in shipments in
the year the standard takes effect. In the preservation-of-gross-margin-percentage
scenario, the slight increase in cash flow from the higher MSP is outweighed by the $45.8
million in conversion costs, causing a slightly negative change in INPV at TSL 1 under
this scenario. Under the preservation-of-operating-profit scenario, manufacturers earn
the same per-unit operating profit as would be earned in the no-new-standards case, but
manufacturers do not earn additional profit from their investments. In this scenario, the
manufacturer markup decreases in 2028, the year after the analyzed 2027 compliance
year. This reduction in the manufacturer markup and the $45.8 million in conversion
costs incurred by manufacturers cause a slightly negative change in INPV at TSL 1 under
the preservation-of-operating-profit scenario.
At TSL 2, the standard reflects efficiency levels with more advanced automatic
termination controls for electric standard, electric compact (120V), vented electric
193
compact (240V), vented gas standard, and ventless electric compact (240V), and high-
speed spin for ventless electric combination washer-dryer. The change in INPV is
expected to range from -2.6 to -2.2 percent. At this level, free cash flow is estimated to
decrease 19.8 percent compared to the no-new-standards case value of $136.7 million in
the year 2026, the year before the 2027 standards year. DOE’s shipments analysis
estimates approximately 58 percent of current shipments meet this level.
The design options for electric standard, electric compact (120V), vented electric
compact (240V), vented gas standard, and ventless electric compact (240V) include
implementing electronic controls, optimized heating systems, and more advanced
automatic termination controls. For ventless electric combination washer-dryer, the
design option analyzed includes high-speed spin cycles. For the electric standard, electric
compact (120V), and vented electric compact (240V), TSL 2 corresponds to EL 3. For
vented gas standard, TSL 2 corresponds to EL 2. For ventless electric compact (240V)
and ventless electric combination washer-dryer, TSL 2 corresponds to EL 1. Capital
conversion costs may be necessary for incremental updates in tooling. Product
conversion costs may be necessary for software optimization, prototyping, and testing.
DOE expects industry to incur some re-flooring costs as manufacturers redesign product
lines to meet the efficiency levels required by TSL 2. DOE estimates capital conversion
costs of $31.9 million and product conversion costs of $37.6 million. Conversion costs
total $69.5 million.
At TSL 2, the shipment-weighted average MPC for all consumer clothes dryers is
expected to increase by 0.6 percent relative to the no-new-standards case shipment-
194
weighted average MPC for all consumer clothes dryers in 2027. Given the relatively
small increase in production costs, DOE does not project a notable drop in shipments in
the year the standard takes effect. In the preservation-of-gross-margin-percentage
scenario, the slight increase cash flow from the higher MSP is outweighed by the $69.5
million in conversion costs, causing a slightly negative change in INPV at TSL 2 under
this scenario. Under the preservation-of-operating-profit scenario, the manufacturer
markup decreases in 2028, the year after the analyzed 2027 compliance year. This
reduction in the manufacturer markup and the $69.5 million in conversion costs incurred
by manufacturers cause a negative change in INPV at TSL 2 under the preservation-of-
operating-profit scenario.
At TSL 3 (i.e., the Recommended TSL), the standard reflects a set of efficiency
levels between the levels designated in TSL 2 and TSL 4. The change in INPV is
expected to range from -6.8 to -5.7 percent. At this level, free cash flow is estimated to
decrease 55.2 percent compared to the no-new-standards case value of $136.6 million in
the year 2027, the year before the 2028 standards year. DOE’s shipments analysis
estimates approximately 48 percent of current shipments meet this level.
The design options analyzed for electric standard, electric compact (120V),
vented electric compact (240V), and vented gas standard include implementing electronic
controls, optimized heating systems, more advanced automatic termination controls, and
modulating heat. For ventless electric compact (240V) and ventless electric combination
washer-dryer, the design options analyzed are the same as TSL 2. For electric standard,
electric compact (120V), and vented electric compact (240V), TSL 3 corresponds to EL
195
4. For vented gas standard, TSL 3 corresponds to EL 3. For ventless electric compact
(240V) and ventless electric combination washer-dryer, TSL 3 corresponds to EL 1. The
incremental increase in industry conversion costs from the prior TSL are due to the
higher efficiency level requirements for electric standard, electric compact (120V),
vented electric compact (240V), and vented gas standard. Capital conversion costs may
be necessary as manufacturers increase tooling for two-stage heating systems. Product
conversion costs may be necessary for prototyping and testing. DOE expects industry to
incur similar re-flooring costs as with TSL 2. DOE estimates capital conversion costs of
$128.9 million and product conversion costs of $51.7 million. Conversion costs total
$180.7 million.
At TSL 3, the shipment-weighted average MPC for all consumer clothes dryers is
expected to increase by 1.7 percent relative to the no-new-standards case shipment-
weighted average MPC for all consumer clothes dryers in 2028. Given the relatively
small increase in production costs, DOE does not project a notable drop in shipments in
the year the standard takes effect. In the preservation-of-gross-margin-percentage
scenario, the increase in cash flow from the higher MSP is outweighed by the $180.7
million in conversion costs, causing a negative change in INPV at TSL 3 under this
scenario. Under the preservation-of-operating-profit scenario, the manufacturer markup
decreases in 2029, the year after the analyzed 2028 compliance year. This reduction in
the manufacturer markup and the $180.7 million in conversion costs incurred by
manufacturers cause a negative change in INPV at TSL 3 under the preservation-of-
operating-profit scenario.
196
At TSL 4, the standard reflects the maximum national energy savings with a
simple PBP of less than 4 years. The change in INPV is expected to range from -29.0 to -
18.5 percent. At this level, free cash flow is estimated to decrease by 212.5 percent
compared to the no-new-standards case value of $136.7 million in the year 2026, the year
before the 2027 standards year. DOE’s shipments analysis estimates approximately 15
percent of current shipments meet this level.
The design options analyzed for electric standard include implementing electronic
controls, optimized heating systems, more advanced automatic termination controls,
modulating heat, and inlet air preheat. For the remaining product classes, the efficiency
levels and analyzed design options for TSL 4 are the same as TSL 3. The incremental
increase in industry conversion costs from the prior TSL is due to the efficiency level
requirements for electric standard. There is very little industry experience with inlet air
preheat designs. Currently, DOE is not aware of any consumer clothes dryers on the
market utilizing this design option. Electric standard dryers account for an estimated 81
percent of domestic consumer clothes dryer shipments. Of these standard electric dryer
shipments, DOE estimates only 7 percent meet or exceed the efficiency level required by
TSL 4. Implementing inlet air preheat represents a major overhaul of existing product
lines and manufacturing facilities. For capital conversion costs, this change might
necessitate significant new equipment and tooling. Product conversion costs may be
necessary for designing, prototyping, and testing new or updated platforms. DOE
expects industry to incur more re-flooring costs compared to prior TSLs as more display
units would need to be replaced with high-efficiency models. DOE estimates capital
197
conversion costs of $579.7 million and product conversion costs of $87.7 million.
Conversion costs total $667.5 million.
At TSL 4, the large conversion costs result in free cash flow dropping below zero
in the years before the standards year. The negative free cash-flow calculation indicates
manufacturers may need to access cash reserves or outside capital to finance conversion
efforts.
At this level, the shipment-weighted average MPC for all consumer clothes dryers
is expected to increase by 13 percent relative to the no-new-standards case shipment-
weighted average MPC for all consumer clothes dryers in 2027. Given the projected
increase in production costs, DOE estimates a less than 1-percent drop in shipments in
the year the standard takes effect compared to the no-new-standards case. In the
preservation-of-gross-margin-percentage scenario, the increase in cash flow from the
higher MSP is outweighed by the $667.5 million in conversion costs, causing a negative
change in INPV at TSL 4 under this scenario. Under the preservation-of-operating-profit
scenario, the manufacturer markup decreases in 2028, the year after the analyzed 2027
compliance year. This reduction in the manufacturer markup and the $667.5 million in
conversion costs incurred by manufacturers cause a negative change in INPV at TSL 4
under the preservation-of-operating-profit scenario.
At TSL 5, the standard reflects the maximum national energy savings with
maximum positive NPV. The change in INPV is expected to range from -67.9 to -14.9
percent. At this level, free cash flow is estimated to decrease by 462.9 percent compared
198
to the no-new-standards case value of $136.7 million in the year 2026, the year before the
2027 standards year. DOE’s shipments analysis estimates approximately 2 percent of
current shipments meet this level.
The design option analyzed for electric standard includes implementing heat
pump technology. The design options analyzed for the vented electric compact (240V)
and vented gas standard include implementing electronic controls, optimized heating
systems, more advanced automatic termination controls, modulating heat, and inlet air
preheat. For electric compact (120V), ventless electric compact (240V), and ventless
electric combination washer-dryer, the design options analyzed are the same as the prior
TSL. For electric standard, TSL 5 corresponds to EL 7. For electric compact (120V) and
vented gas standard, TSL 5 corresponds to EL 4. For vented electric compact (240V),
TSL 5 corresponds to EL 5. For ventless electric compact (240V) and ventless electric
combination washer-dryer, TSL 5 corresponds to EL 1.
At TSL 5, conversion costs are largely driven by the max-tech efficiency level
required for electric standard and vented gas standard. As previously discussed, electric
standard dryers account for 81 percent of domestic consumer clothes dryer shipments.
Currently, there are few electric standard models on the U.S. market that meet the max-
tech efficiency level required by TSL 5. Of the 13 OEMs identified that offer electric
standard dryers, only five OEMs manufacture electric standard dryers that utilize heat
pump technology. Of these five OEMs, four OEMs offer approximately six models
(accounting for less than 1 percent of electric standard model listings) that meet the max-
tech level required at TSL 5. Nearly all manufacturers would need to significantly update
199
facilities to meet a heat pump efficiency level for electric standard dryers. Mandating a
heat pump efficiency level for this product class would require many manufacturers to
design completely new clothes dryer platforms or adapt heat pump designs from other
markets (i.e., redesign European heat pump models to adhere to U.S. safety standards and
consumer preferences).
Vented gas standard dryers account for approximately 17 percent of domestic
consumer clothes dryer shipments. Manufacturers would need to implement inlet air
preheat technology along with other design options to meet the efficiency levels required
by TSL 5. Thus far, dryers with this technology and performance have not been observed
in clothes dryers available on the consumer market. Clothes dryers with inlet air preheat
designs have been observed only in laboratory settings. In interviews, some
manufacturers raised concerns about implementing a relatively untested technology for
the consumer market. There is very little industry experience with inlet air preheat
designs. Several manufacturers speculated that implementing inlet air preheat technology
would require a major overhaul of existing production facilities and a significant amount
of engineering time.
DOE expects industry to incur more re-flooring costs compared to prior TSLs, as
nearly all display units would need to be replaced with high-efficiency models. DOE
estimates capital conversion costs of $1,314.3 million and product conversion costs of
$122.6 million. Conversion costs total $1,436.9 million.
200
As with TSL 4, the large conversion costs result in free cash flow dropping below
zero in the years before the standard year. The negative free cash-flow calculation
indicates manufacturers may need to access cash reserves or outside capital to finance
conversion efforts.
At this level, the shipment-weighted average MPC for all consumer clothes dryers
is expected to increase by 63.2 percent relative to the no-new-standards case shipment-
weighted average MPC for all consumer clothes dryers in 2027. Given the projected
increase in production costs, DOE expects an estimated 11-percent drop in shipments in
the year the standard takes effect compared to the no-new-standards case. In the
preservation-of-gross-margin-percentage scenario, the increase in MSP is outweighed by
the $1,436.9 million in conversion costs and the drop in annual shipments, causing a
negative change in INPV at TSL 5 under this scenario. Under the preservation-of-
operating-profit scenario, the manufacturer markup decreases in 2028, the year after the
analyzed 2027 compliance year. This large reduction in manufacturer markup, the
$1,436.9 million in conversion costs incurred by manufacturers, and the drop in annual
shipments cause a significantly negative change in INPV at TSL 5 under the
preservation-of-operating-profit scenario.
At TSL 6, the standard reflects max-tech efficiency for all product classes. The
change in INPV is expected to range from -71.4 to -17.1 percent. At this level, free cash
flow is estimated to decrease by 488.8 percent compared to the no-new-standards case
value of $136.7 million in the year 2026, the year before the 2027 standards year. DOE’s
201
shipments analysis estimates approximately 1 percent of current shipments meet this
level.
The design option analyzed for TSL 6 incorporates heat pump technology for
electric standard, electric compact (120V), vented electric compact (240V), ventless
electric compact (240V), and ventless electric combination washer-dryer. For vented gas
standard, the design options analyzed include implementing electronic controls,
optimized heating systems, more advanced automatic termination controls, modulating
heat, and inlet air preheat.
Of the 19 OEMs that manufacture electric consumer clothes dryers (i.e., electric
standard, electric compact (120V), vented electric compact (240V), ventless electric
compact (240V), ventless electric combination washer-dryer), 10 OEMs do not currently
offer any consumer clothes dryer models for the U.S. market that utilize heat pump
technology. Of the 13 OEMs that offer electric standard clothes dryers, four OEMs
currently offer some models that meet the max-tech heat pump level. Of the 10 OEMs
that offer electric compact (120V) clothes dryers, one OEM offers a model that meets the
max-tech level. Of the five OEMs that offer vented electric compact (240V) clothes
dryers, one OEM offers models that meet the max-tech level. Of the 13 OEMs that offer
ventless electric compact (240V) clothes dryers, one OEM offers a model that meets the
max-tech level. Of the five OEMs that offer ventless electric combination washer-dryer,
two OEMs offer models that meet the max-tech level.
202
A standard that could only be met using heat pump technology could require a
total renovation of existing facilities and completely new clothes dryer platforms for
manufacturers that do not offer heat pump clothes dryers today. In interviews, two
OEMs with significant market shares stated that they would require additional facilities to
handle dryer manufacturing under a standard that could only be met using heat pump
technology. As previously discussed, implementing inlet air preheat also represents a
major overhaul of existing vented gas product lines. DOE expects industry to incur
slightly more re-flooring costs compared to TSL 5, as all display models below max-tech
efficiency would need to be replaced due to the higher standard. At TSL 6, reaching
max-tech efficiency levels is a billion-dollar investment for industry. DOE estimates
capital conversion costs of $1,388.8 million and product conversion costs of $128.2
million. Conversion costs total $1,516.9 million.
As with TSL 4 and TSL 5, the large conversion costs result in free cash flow
dropping below zero in the years before the standard year. The negative free cash-flow
calculation indicates manufacturers may need to access cash reserves or outside capital to
finance conversion efforts.
At this level, the shipment-weighted average MPC for all consumer clothes dryers
is expected to increase by 64.7 percent relative to the no-new-standards case shipment-
weighted average MPC for all consumer clothes dryers in 2027. Given the projected
increase in production costs, DOE expects an estimated 11-percent drop in shipments in
the year the standard takes effect compared to the no-new-standards case. In the
preservation-of-gross-margin-percentage scenario, the large increase in MSP is still
203
outweighed by the $1,516.9 million in conversion costs and drop in annual shipments,
causing a moderately negative change in INPV at TSL 6 under this scenario. Under the
preservation-of-operating-profit scenario, the manufacturer markup decreases in 2028,
the year after the analyzed 2027 compliance year. This large reduction in manufacturer
markup, the $1,516.9 million in conversion costs incurred by manufacturers, and the drop
in annual shipments cause a significantly negative change in INPV at TSL 6 under the
preservation-of-operating-profit scenario.
b. Direct Impacts on Employment
To quantitatively assess the potential impacts of amended energy conservation
standards on direct employment in the consumer clothes dryer industry, DOE used the
GRIM to estimate the domestic labor expenditures and number of direct employees in the
no-new-standards case and in each of the standards cases during the analysis period. For
the direct final rule, DOE used the most up-to-date information available. DOE calculated
these values using statistical data from the U.S. Census Bureau’s 2021 ASM,
117
the U.S.
Bureau of Labor Statistics’ employee compensation data,
118
results of the engineering
analysis, and manufacturer interviews.
Labor expenditures related to product manufacturing depend on the labor intensity
of the product, the sales volume, and an assumption that wages remain fixed in real terms
over time. The total labor expenditures in each year are calculated by multiplying the
117
U.S. Census Bureau, Annual Survey of Manufactures: Summary Statistics for Industry Groups and
Industries in the U.S.: 20182021. Available at www.census.gov/programs-surveys/asm/data/tables.html
(last accessed May 23, 2023).

Available at www.bls.gov/news.release/pdf/ecec.pdf (last accessed June 8, 2023).
204
total MPCs by the labor percentage of MPCs. The total labor expenditures in the GRIM
were then converted to total production employment levels by dividing production labor
expenditures by the average fully burdened wage multiplied by the average number of
hours worked per year per production worker. To do this, DOE relied on ASM inputs:
Production Workers Annual Wages, Production Workers Annual Hours, Production
Workers for Pay Period, and Number of Employees. DOE also relied on BLS employee
compensation data to determine the fully burdened wage ratio. The fully burdened wage
ratio factors in paid leave, supplemental pay, insurance, retirement and savings, and
legally required benefits.
The number of production employees is then multiplied by the U.S. labor
percentage to convert total production employment to total domestic production
employment. The U.S. labor percentage represents the industry fraction of domestic
manufacturing production capacity for the covered product. This value is derived from
manufacturer interviews, product database analysis, and publicly available information.
For the August 2022 NOPR, DOE estimated that approximately 58 percent of consumer
clothes dryers were produced domestically. In support of this direct final rule analysis,
DOE conducted further research to ensure this estimate was still accurate. Based on a
review of publicly available data, DOE estimates that 60 percent of consumer clothes
dryers are produced domestically.
The domestic production employees estimate covers production line workers,
including line supervisors, who are directly involved in fabricating and assembling
products within the OEM facility. Workers performing services that are closely
205
associated with production operations, such as materials-handling tasks using forklifts,
are also included as production labor. DOE’s estimates only account for production
workers who manufacture the specific products covered by this amended rulemaking.
Non-production workers account for the remainder of the direct employment
figure. The non-production employees estimate covers domestic workers who are not
directly involved in the production process, such as sales, engineering, human resources,
and management. Using the amount of domestic production workers calculated above,
non-production domestic employees are extrapolated by multiplying the ratio of non-
production workers in the industry compared to production employees. DOE assumes
that this employee distribution ratio remains constant between the no-new-standards case
and standards cases.
Using the GRIM, DOE estimates that in the absence of new energy conservation
standards, there would be 2,725 domestic production and non-production workers for
consumer clothes dryers in 2027. Table V.28 shows the range of the impacts of energy
conservation standards on U.S. manufacturing employment in the consumer clothes dryer
industry. The following discussion provides a qualitative evaluation of the range of
potential impacts presented in Table V.28.

** In 2028, the no-new-standards case direct employment estimate is 2,744.
*** DOE presents a range of potential employment impacts. Parentheses denote negative values.
The direct employment impacts shown in Table V.29 represent the potential
domestic employment changes that could result following the compliance date for the
consumer clothes dryer product classes in this amended rule. The upper-bound estimate
corresponds to an increase in the number of domestic workers that would result from
amended energy conservation standards if manufacturers continue to produce the same
scope of covered products within the United States after compliance takes effect. The
lower-bound estimate represents the maximum decrease in production workers if
manufacturing moved to lower labor-cost countries. Most manufacturers currently
produce at least a portion of their consumer clothes dryers in countries with lower labor
costs, and an amended standard that necessitates large increases in labor content or large
expenditures to retool facilities could cause manufacturers to reevaluate domestic
production siting options. However, the Recommended TSL (i.e., TSL 3) would likely
not require significant increases in labor content or significant capital investments. As
207
such, DOE expects that the likelihood of changes in production location as a direct result
of amended standards are relatively low.
Additional detail on the analysis of direct employment can be found in chapter 12
of the direct final rule TSD. Additionally, the employment impacts discussed in this
section are independent of the employment impacts from the broader U.S. economy,
which are documented in chapter 16 of the direct final rule TSD.
c. Impacts on Manufacturing Capacity
As discussed in section V.B.2.a of this document, implementing the different
design options analyzed for this direct final rule would require varying levels of resources
and investment. A standard level that would require the use of heat pump technology for
electric dryers and combination washer-dryers would represent the biggest shift in
technology for clothes dryer manufacturing among all the design options considered for
this analysis. Adopting efficiency levels that require heat pump technology would
necessitate very large investments to both redesign products and update production
facilities. Currently, DOE estimates that approximately 1 percent of consumer clothes
dryer shipments meet the analyzed max-tech heat pump efficiency levels. In interviews,
several manufacturers expressed concern that the 3-year EPCA-specified time period
between the announcement of a final rule and the compliance date of the amended energy
conservation standard might be insufficient to design, test, and manufacture the necessary
number of products to meet demand.
208
In interviews, some manufacturers raised concerns about implementing inlet air
preheat designs. Unlike the discussions about heat pump technology, there is very little
industry experience with inlet air preheat designs. Currently, no models on the U.S.
market incorporate this design option. Several manufacturers speculated that
implementing inlet air preheat would require a major overhaul of existing production
facilities and a significant amount of engineering time.
However, because TSL 3 (i.e., the Recommended TSL) would not require heat
pump technology or inlet air preheat designs, DOE does not expect manufacturers to face
long-term capacity constraints due to the standard levels detailed in this direct final rule.
Furthermore, at the Recommended TSL, manufacturers will have a 4-year period
between the announcement of the direct final rule and the compliance date of the
amended energy conservation standards to redesign products to meet the adopted
standard levels.
d. Impacts on Subgroups of Manufacturers
Using average cost assumptions to develop industry cash flow estimates may not
capture the differential impacts among subgroups of manufacturers. Small
manufacturers, niche players, or manufacturers exhibiting a cost structure that differs
substantially from the industry average could be affected disproportionately. DOE
investigated small businesses as a manufacturer subgroup that could be disproportionally
impacted by energy conservation standards and could merit additional analysis. DOE did
not identify any other adversely impacted manufacturer subgroups for this rulemaking
based on the results of the industry characterization.
209
DOE analyzes the impacts on small businesses in a separate analysis for the
standards proposed in the NOPR published elsewhere in this issue of the Federal
Register and in chapter 12 of the direct final rule TSD. For a discussion of the impacts
on the small business manufacturer subgroup, see chapter 12 of the direct final rule TSD.
e. Cumulative Regulatory Burden
One aspect of assessing manufacturer burden involves looking at the cumulative
impact of multiple DOE standards and the regulatory actions of other Federal agencies
and States that affect the manufacturers of a covered product or equipment. While any
one regulation may not impose a significant burden on manufacturers, the combined
effects of several existing or impending regulations may have serious consequences for
some manufacturers, groups of manufacturers, or an entire industry. Multiple regulations
affecting the same manufacturer can strain profits and lead companies to abandon product
lines or markets with lower expected future returns than competing products. For these
reasons, DOE conducts an analysis of cumulative regulatory burden as part of its
rulemakings pertaining to appliance efficiency.
For the cumulative regulatory burden analysis, DOE examines Federal, product-
specific regulations that could affect consumer clothes dryer manufacturers that take
effect approximately 3 years before or after the 2028 compliance date. This information
is presented in Table V.29.

* This column presents the total number of OEMs identified in the energy conservation standard rule that is
contributing to cumulative regulatory burden.
** This column presents the number of OEMs producing consumer clothes dryers that are also listed as
OEMs in the identified energy conservation standard that is contributing to cumulative regulatory burden.
*** This column presents industry conversion costs as a percentage of equipment revenue during the
conversion period. Industry conversion costs are the upfront investments manufacturers must make to sell
compliant products/equipment. The revenue used for this calculation is the revenue from just the covered
product/equipment associated with each row. The conversion period is the time frame over which
conversion costs are made and lasts from the publication year of a final rule to the compliance year of the
energy conservation standard. The conversion period typically ranges from 3 to 5 years, depending on the
rulemaking.
These rulemakings are at the NOPR stage, and all values are subject to change until finalized through
publication of a final rule.
For the refrigerators, refrigerator-freezers, and freezers energy conservation standards direct final rule, the
compliance year (2029 or 2030) varies by product class.
As shown in Table V.29, the rulemakings with the largest overlap of consumer
clothes dryer OEMs include residential clothes washers, consumer conventional cooking
products, dishwashers, refrigerators, refrigerator-freezers, and freezers, and
miscellaneous refrigeration products, which are all part of the multi-product Joint
Agreement submitted by interested parties.
119
As detailed in the Joint Agreement, the
signatories indicated that their recommendations should be considered a “complete
package.” The signatories further stated that “each part of this agreement is contingent
upon the other parts being implemented.” (Joint Agreement, No. 55, p. 3)
119
The microwave ovens energy conservation standards final rule (88 FR 39912), which has 11
overlapping OEMs, was published prior to the joint submission of the multi-product Joint Agreement.
212
The multi-product Joint Agreement states the “jointly recommended compliance
dates will achieve the overall energy and economic benefits of this agreement while
allowing necessary lead-times for manufacturers to redesign products and retool
manufacturing plants to meet the recommended standards across product categories.”
(Joint Agreement, No. 55 at p. 2) The staggered compliance dates help mitigate
manufacturers’ concerns about their ability to allocate sufficient resources to comply with
multiple concurrent amended standards and about the need to align compliance dates for
products that are typically designed or sold as matched pairs (such as residential clothes
washers and consumer clothes dryers). See section IV.J.3 of this document for
stakeholder comments about cumulative regulatory burden. See Table V.30 for a
comparison of the estimated compliance dates based on EPCA-specified timelines and

3. National Impact Analysis
This section presents DOE’s estimates of the national energy savings and the
NPV of consumer benefits that would result from each of the TSLs considered as
potential amended standards.
a. Significance of Energy Savings
To estimate the energy savings attributable to potential amended standards for
consumer clothes dryers, DOE compared clothes dryer energy consumption under the no-
new-standards case to their anticipated energy consumption under each TSL. The
savings are measured over the entire lifetime of products purchased in the 30-year period
that begins in the year of anticipated compliance with amended standards (2027–2056).
120
Table V.31 presents DOE’s projections of the national energy savings for each TSL
considered for consumer clothes dryers. The savings were calculated using the approach
described in section IV.H.2 of this document.

214
benefits and costs. Circular A-4 also directs agencies to consider the variability of key
elements underlying the estimates of benefits and costs. For this rulemaking, DOE
undertook a sensitivity analysis using 9 years, rather than 30 years, of product shipments.
The choice of a 9-year period is a proxy for the timeline in EPCA for the review of
certain energy conservation standards and potential revision of and compliance with such
revised standards.
121
The review timeframe established in EPCA is generally not
synchronized with the product lifetime, product manufacturing cycles, or other factors
specific to consumer clothes dryers. Thus, such results are presented for informational
purposes only and are not indicative of any change in DOE’s analytical methodology.
The NES sensitivity analysis results based on a 9-year analytical period are presented in
Table V.32. The impacts are counted over the lifetime of consumer clothes dryers
purchased during the period 2027–2035.

EPCA requires DOE to review its standards at least once every 6 years, and requires, for certain
products, a 3-year period after any new standard is promulgated before compliance is required, except that
in no case may any new standards be required within 6 years of the compliance date of the previous
standards. While adding a 6-year review to the 3-year compliance period adds up to 9 years, DOE notes
that it may undertake reviews at any time within the 6-year period and that the 3-year compliance date may
yield to the 6-year backstop. A 9-year analysis period may not be appropriate given the variability that
occurs in the timing of standards reviews and the fact that for some products, the compliance period is 5
years rather than 3 years.
122
The analysis period for TSL 3 (the Recommended TSL) is 20282036.
215
b. Net Present Value of Consumer Costs and Benefits
DOE estimated the cumulative NPV of the total costs and savings for consumers
that would result from the TSLs considered for consumer clothes dryers. In accordance
with OMB’s guidelines on regulatory analysis, DOE calculated NPV using both a 7-
percent and a 3-percent real discount rate. Table V.33 shows the consumer NPV results
with impacts counted over the lifetime of products purchased during the period 2027–
2056.

The previous results reflect the use of a default trend to estimate the change in
price for consumer clothes dryers over the analysis period (see section IV.F.1 of this
document). DOE also conducted a sensitivity analysis that considered one scenario with
a lower rate of price decline than the reference case and one scenario with a higher rate of
price decline than the reference case. The results of these alternative cases are presented
in appendix 10C of the direct final rule TSD. In the high-price-decline case, the NPV of
consumer benefits is higher than in the default case. In the lower-price-decline case, the
NPV of consumer benefits is lower than in the default case.
c. Indirect Impacts on Employment
DOE estimates that amended energy conservation standards for consumer clothes
dryers will reduce energy expenditures for consumers of those products, with the
resulting net savings being redirected to other forms of economic activity. These
expected shifts in spending and economic activity could affect the demand for labor. As
described in section IV.N of this document, DOE used an input/output model of the U.S.
economy to estimate indirect employment impacts of the TSLs that DOE considered.
There are uncertainties involved in projecting employment impacts, especially changes in
217
the later years of the analysis. Therefore, DOE generated results for near-term
timeframes (2027–2033)
123
, where these uncertainties are reduced.
The results suggest that the adopted standards are likely to have a negligible
impact on the net demand for labor in the economy. The net change in jobs is so small
that it would be imperceptible in national labor statistics and might be offset by other,
unanticipated effects on employment. Chapter 16 of the direct final rule TSD presents
detailed results regarding anticipated indirect employment impacts.
4. Impact on Utility or Performance of Products
As discussed in section III.E.1.d of this document, DOE has concluded that the
standards adopted in this direct final rule will not lessen the utility or performance of the
consumer clothes dryers under consideration in this rulemaking. Manufacturers of these
products currently offer units that meet or exceed the adopted standards.
In response to the August 2022 NOPR, AHAM stated that DOE must ensure that
amended standards do not lengthen cycle times, and AHAM believes that in order to
achieve the test procedure’s current FMC requirement and meet the standards proposed in
the August 2022 NOPR, cycle lengths will get longer. Whirlpool commented that the
strategies used in consumer clothes dryers certified under appendix D2 often lower the
overall average drying temperature and extend the drying time to increase the CEF, while
minimally compliant consumer clothes dryers certified under appendix D1 typically
123
The analysis period for TSL 3 (the Recommended TSL) is 20282034.
218
achieve a higher overall temperature and shorten the drying process. Citing DOE’s test
sample, Whirlpool stated that models certified using appendix D1 without wrinkle
prevention mode activated had an average drying time of 56 minutes when tested to
appendix D2, while models certified using appendix D2 had an average drying time of 66
minutes, and ENERGY STAR-qualified products had an average drying time of 71
minutes, the additional time needed to meet the 2-percent FMC requirement. Whirlpool
stated that DOE’s statutory criteria are not met to proceed with the standards proposed in
the August 2022 NOPR due to a clear lessening of performance and utility of the product
associated with longer drying times. (AHAM, No. 46 at pp. 8–10; Whirlpool, No. 53 at p.
4)
DOE’s test data do not support the assertion by AHAM and Whirlpool that
amended standards would necessitate longer drying times. In DOE’s test sample, the
consumer clothes dryers certified under appendix D1 have an average cycle time of 61
minutes when tested in accordance with appendix D2. In comparison, among the units in
DOE’s test sample that are certified under appendix D2 at or above the amended
standard, multiple units have a cycle time less than 60 minutes. This indicates that the
standards adopted by this direct final rule will not necessitate any increase in cycle time
compared to typical cycle times currently associated with baseline consumer clothes
dryers. DOE notes that a 60-minute cycle time is notably less than the 80-minute cycle
time required for ENERGY STAR qualification.
124
DOE further notes that cycle time is
one of many product attributes that consumers consider when purchasing a clothes dryer,
124
ENERGY STAR criteria for consumer clothes dryers can be found at:
www.energystar.gov/products/appliances/clothes_dryers/key_product_criteria.
219
such as drying performance and fabric care. As further examples, Consumer Reports—
which DOE recognizes is one popular resource for consumers seeking independent
reviews of consumer products—highlights the following product attributes for consumer
clothes dryers in addition to cycle time: drying performance, ergonomics, noise level,
capacity, drum material, compatibility with a drying rack, availability of custom
programs, availability of a steam option, moisture sensing capability, Wifi connectivity,
and stackability with an accompanying clothes washer.
125
As noted in section IV.H.2 of this document, DOE has observed a steady decline
in annual consumer clothes dryer cycles over the past 15 years, despite the
implementation of more stringent consumer clothes dryer energy conservation standards,
which is an indication that consumers are not rerunning their clothes dryers. Additionally,
the amended standards correspond to the current ENERGY STAR efficiency level for
both electric and gas standard clothes dryers, which requires testing in accordance with
appendix D2 and which ensures consumer-accepted dryness levels as discussed in section
II.B.2 of this document. As noted above, DOE does not expect increased cycle times
compared to typical cycle times currently associated with baseline consumer clothes
dryers as a result of adopted standards. In addition, DOE does not expect consumers to
re-run the consumer clothes dryer upon completion of the initial run as a result of the
amended standards being adopted in this direct final rule. DOE therefore does not expect
a lessening in performance or utility as a result of the standards adopted by this direct
final rule. As previously discussed, on February 14, 2024, DOE received a second joint
125
Consumer Reports ratings of consumer clothes dryers available at
www.consumerreports.org/appliances/clothes-dryers (last accessed February 5, 2024).
220
statement from the same group of stakeholders that submitted the Joint Agreement in
which the signatories reaffirmed the standards recommended in the Joint Agreement.
126
In particular, the letter states that DOE’s test data show, and industry experience agrees,
that the recommended standard levels for consumer clothes dryers will not result in
significant differences in cycle time and will adequately dry clothes.
Whirlpool stated that due to the core technological differences in energy-saving
heat pump clothes dryers (such as lower air temperatures, heat retention, and water
condensing systems) compared to conventional resistive heater clothes dryers, harder-to-
dry fabrics need additional time in a heat pump clothes dryer to remove their embedded
moisture and some heat pump clothes dryers may not get down to the required FMC.
(Whirlpool, No. 53 at pp. 12–13)
With regard to Whirlpool’s concerns about the performance of heat pump clothes
dryers for certain hard-to-dry fabrics, DOE notes that the standards adopted by this direct
final rule do not require the use of heat pump technology. AHAM stated that longer
consumer clothes dryer cycle times may create different cycle times between clothes
washers and clothes dryers, which may result in different consumer behaviors.
According to AHAM, different operating times in laundry products may result in the
increased use of wrinkle control cycles or redrying loads to avoid wrinkled clothes
resulting from the clothes sitting in the clothes dryer for more extended periods of time,
or in consumers re-washing clothes that were not transferred to the clothes dryer due to a
126
This document is available in the docket at: www.regulations.gov/comment/EERE-2014-BT-STD-0058-
0058.
221
previous load still being dried, ultimately resulting in increased water and energy use.
AHAM also stated that consumers could turn to using other cycles, thus undercutting
savings designed to be achieved through use of the normal cycle. AHAM and Whirlpool
therefore stated that DOE should evaluate the impact of amended standards on drying
times as cycle length is a performance feature associated with consumer preferences that
consumers are unlikely to accept if cycles are too long and do not match washing times.
AHAM also disagreed with DOE’s use of the maximum drying time of 80 minutes in the
current ENERGY STAR specification as a benchmark for its analysis, asserting that the
specification was not based on sufficient supporting or consumer-relevant data. (AHAM,
No. 46 at pp. 8–10)
As previously stated, DOE does not expect a shift in consumer drying times
associated with amended standards beyond what is typically experienced by consumers
of baseline consumer clothes dryers. Additionally, DOE does not expect that the
amended standards would result in longer drying cycles given the prevalence on the
market of consumer clothes dryers that meet the amended standard with cycle times
comparable to those of current baseline models, regardless of the longer cycle time of 80
minutes allowed in the ENERGY STAR specification. Therefore, DOE has no basis to
conclude that the amended standards would alter the existing relative cycle times between
consumer clothes dryers and clothes washers.
The test data presented in the August 2022 NOPR contradict certain conclusions
and presumptions made by DOE in previous rulemakings with regard to cycle times. In
particular, in a NOPR published on August 13, 2020 (“August 2020 NOPR”), which
222
preceded the December 2020 Final Rule, DOE stated its presumption that the shortest
possible cycle times currently available on the market represent the models for which
certain manufacturers have prioritized cycle time while maintaining adequate drying
performance and other performance aspects of consumer clothes dryers; and that based
on this presumption, the current energy conservation standards may have discouraged
manufacturers from bringing models to the market with cycle times of 30 minutes or less.
85 FR 49297, 49305 reiterated at 85 FR 81359, 81361. DOE further asserted that offering
products with shorter cycle times would require more per-cycle energy use than would be
permitted under the current standards in order to maintain the same level of performance
in other areas. 85 FR 49297, 49299.
DOE has determined, contrary to the August 2020 NOPR’s assumptions, that
current energy conservation standards have not prevented the sale of consumer clothes
dryers with shorter cycle times. DOE’s test data presented in the August 2022 NOPR
indicate no discernable correlation between efficiency level and cycle time for vented
electric standard dryers or vented gas clothes dryers (i.e., the consumer clothes dryer
product classes subject to the December 2020 Final Rule) Indeed, for vented electric
standard clothes dryers, the most efficient model in DOE’s test sample has a shorter cycle
time (80 minutes) than the least efficient minimally-compliant model in DOE’s test
sample (98 minutes). The models with the lowest cycle times of 36 and 39 minutes both
achieve higher efficiency level EL 3. Similarly, for vented gas clothes dryers, the most
efficient model in DOE’s test sample has a cycle time of 66 minutes, substantially similar
to the baseline unit with a cycle time of 65 minutes. The models with the lowest cycle
times of 35 and 36 minutes both achieve higher efficiency level EL 2. Based on this data,
223
DOE reaches a different conclusion than was reached in the December 2020 Final Rule.
In particular, noting that DOE’s data show no discernable correlation between efficiency
and cycle time, this data does not support DOE’s prior assertion that the current
consumer clothes dryer energy conservation standards may be precluding manufacturers
from bringing models to the market with substantially shorter cycle times, or DOE’s prior
presumption that offering products with shorter cycle times would require more per-cycle
energy use than would be permitted under the current standards.
Furthermore, in the second joint statement submitted February 14, 2024, by the
signatories of the Joint Agreement, the signatories acknowledge that DOE’s investigative
testing shows that there is no significant difference in cycle time between consumer
clothes dryers in DOE’s data set that are less efficient than the recommended standards
and those that just meet the recommended standard levels. The signatories noted, for
example, that the difference in average cycle time is only about 2 minutes between
electric standard clothes dryers in DOE’s data set that are less efficient than the
recommended standard and those that just meet the recommended standard (with CEFs of
3.93 and 3.94). Moreover, the signatories stated that the electric standard clothes dryers
in DOE’s data set that are less efficient than the recommended standards include models
with longer cycle times than those that meet the recommended standards, suggesting that
cycle time is tied to more than efficiency alone.
Finally, for the reasons previously discussed, DOE has also determined that the
standards adopted in this direct final rule will not result in any significant differences in
drying cycle times.
224
AHAM and Whirlpool commented that longer cycle times also cause more wear
and tear on clothing as well as on the product itself and can decrease the lifetime of the
product and increase the need for repair. Whirlpool stated that longer cycles lead to
consumer perception that their clothes are being damaged and potentially lead consumers
to interrupt consumer clothes dryer cycles to prevent garment damage, depending on
different fabric types/thicknesses. Whirlpool commented that when presented with the
concept of a lower-heat and slower-drying cycle that would save energy, consumers were
not enthusiastic and did not trust that such a drying strategy would prevent garment
damage or match clothes washer cycle times. Whirlpool stated that, according to its
provided research focused on thread removal counts on test cloth, there is the possibility
of increased fabric damage with longer drying times when the test cloth is in a semi-
saturated state. Whirlpool commented that every 30 minutes of drying time for semi-
saturated fabric is equivalent to 2.4 times the amount of fabric damage that would have
been seen with one complete wash cycle in a front-load clothes washer. Whirlpool
commented that this research showed 17-percent thread removal from 7 minutes of
drying under appendix D1 testing and 40-percent thread removal from 30 minutes of
drying under appendix D2 testing. Whirlpool stated that according to these results,
appendix D2 testing resulted in a longer drying time in which the test cloth was in a semi-
saturated state, as well as 2.4 times the fabric damage as a consumer clothes dryer cycle
under appendix D1 testing. According to Whirlpool, the longer the drying cycle is drawn
out at lower temperatures, the more total friction and thread removal occurs as the semi-
saturated clothes rub together when tumbling in the drum. Whirlpool asserted that fabric
care is partially a story of cycle temperature and mechanical damage from extended
225
drying times, and although there may be some benefit from lower temperatures, the
potentially increased mechanical damage from longer cycles cannot be ignored, nor the
additional cost burden associated with consumers replacing damaged or worn clothing
that was not factored into DOE’s analysis. AHAM stated that manufacturers would also
have to plan for increased wear and tear on the product itself with more robust
components; therefore, AHAM disagreed with DOE’s conclusion that repair and
maintenance costs would not change with the proposed standard. Both AHAM and
Whirlpool stated that DOE should account for the impacts of energy conservation
standards associated with increased drying times on fabric care and the additional cost
burden in its analysis. (AHAM, No. 46 at pp. 9–10; Whirlpool, No. 53 at p. 5)
The fabric care data Whirlpool shared shows increased thread removal from
drying under appendix D2 testing compared to testing under appendix D1 for the same
unit, which according to Whirlpool is due to longer drying times when the test cloth is in
a semi-saturated state. However, DOE notes that amended standards would not require
any specific drying strategy (e.g., longer cycle times, longer drying time at the semi-
saturated state, lower drying temperatures) to ensure the FMC requirement or amended
standards are met nor preclude shorter drying times at the semi-saturated state.
Additionally, DOE notes that this testing did not compare the thread removal from drying
for units with different efficiencies, but rather the same unit tested under two different
tests, so DOE is not aware of any data substantiating a correlation between increased
efficiency and thread removal. As previously noted, appendix D2 accounts for all
consumer clothes dryers with and without automatic termination control and is therefore
more representative of consumer use than appendix D1, and depending on the automatic
226
termination control system, the appendix D2 cycle time may be longer or shorter than
that when testing in accordance with appendix D1. Furthermore, DOE is not aware of
any information indicating that the higher efficiency levels associated with amended
standards would increase cycle time beyond what is typically experienced by consumers
of baseline consumer clothes dryers, and has determined that existing cycle times can be
met with consumer clothes dryers capable of meeting the amended standards. Therefore,
DOE has concluded the recommend standards that are the subject of this direct final rule
would not result in increased impacts on fabric care and product wear and tear as AHAM
and Whirlpool suggested. Additionally, DOE notes that AHAM recommended the
efficiency levels proposed in the August 2022 NOPR for adoption in this direct final rule.
DOE, however, will continue to review relevant data on potential impacts on fabric care
and product wear and tear and may consider it in future rulemakings.
For the reasons discussed throughout this section and based on the additional
confirming statements from the Joint Agreement signatories, DOE has concluded that the
standards adopted in this direct final rule will not lessen the utility or performance of the
consumer clothes dryers under consideration in this rulemaking.
5. Impact of Any Lessening of Competition
DOE considered any lessening of competition that would be likely to result from
new or amended standards. As discussed in section III.E.1.e of this document, EPCA
directs the Attorney General of the United States (“Attorney General”) to determine the
impact, if any, of any lessening of competition likely to result from a proposed standard
and to transmit such determination in writing to the Secretary within 60 days of the
227
publication of a proposed rule, together with an analysis of the nature and extent of the
impact. To assist the Attorney General in making this determination, DOE is providing
the DOJ with copies of this direct final rule and the TSD for review.
6. Need of the Nation to Conserve Energy
Enhanced energy efficiency, where economically justified, improves the Nation’s
energy security, strengthens the economy, and reduces the environmental impacts (costs)
of energy production. Reduced electricity demand due to energy conservation standards
is also likely to reduce the cost of maintaining the reliability of the electricity system,
particularly during peak-load periods. Chapter 15 in the direct final rule TSD presents
the estimated impacts on electricity generating capacity, relative to the no-new-standards
case, for the TSLs that DOE considered in this rulemaking.
Energy conservation resulting from potential energy conservation standards for
consumer clothes dryers is expected to yield environmental benefits in the form of
reduced emissions of certain air pollutants and greenhouse gases. Table V.35 provides
DOE’s estimate of cumulative emissions reductions expected to result from the TSLs
considered in this rulemaking. The emissions were calculated using the multipliers
discussed in section IV.K of this document. DOE reports annual emissions reductions for
each TSL in chapter 13 of the direct final rule TSD.

DOE is well aware that scientific and economic knowledge about the contribution
of CO
2
and other GHG emissions to changes in the future global climate and the potential
resulting damages to the global and U.S. economy continues to evolve rapidly. DOE,
together with other Federal agencies, will continue to review methodologies for
estimating the monetary value of reductions in CO
2
and other GHG emissions. This
ongoing review will consider the comments on this subject that are part of the public
record for this and other rulemakings, as well as other methodological assumptions and
231
issues. DOE notes, however, that the adopted standards would be economically justified
even without inclusion of monetized benefits of reduced GHG emissions.
DOE also estimated the monetary value of the economic benefits associated with
NO
X
and SO
2
emissions reductions anticipated to result from the considered TSLs for
consumer clothes dryers. The dollar-per-ton values that DOE used are discussed in
section IV.L.2 of this document. Table V.39 presents the present value for NO
X
emissions reductions for each TSL calculated using 7-percent and 3-percent discount
rates, and Table V.40 presents similar results for SO
2
emissions reductions. The results
in these tables reflect application of EPA’s low dollar-per-ton values, which DOE used to
be conservative. The time series of annual values is presented for the selected TSL in
chapter 14 of the direct final rule TSD.

Not all the public health and environmental benefits from the reduction of
greenhouse gases, NO
X
, and SO
2
are captured in the values above, and additional
unquantified benefits from the reductions of those pollutants as well as from the
reduction of direct particulate matter (“PM”) and other co-pollutants may be significant.
DOE has not included monetary benefits of the reduction of Hg emissions because the
amount of reduction is very small.
7. Other Factors
The Secretary of Energy, in determining whether a standard is economically
justified, may consider any other factors that the Secretary deems to be relevant. (42
U.S.C. 6295(o)(2)(B)(i)(VII)) No other factors were considered in this analysis.
8. Summary of Economic Impacts
Table V.41 presents the NPV values that result from adding the estimates of the
economic benefits resulting from reduced GHG and NO
X
and SO
2
emissions to the NPV
of consumer benefits calculated for each TSL considered in this rulemaking. The
consumer benefits are domestic U.S. monetary savings that occur as a result of
purchasing the covered products and are measured for the lifetime of products shipped
233
during the period 2027–2056.
127
The climate benefits associated with reduced GHG
emissions resulting from the adopted standards are global benefits and are also calculated
based on the lifetime of consumer clothes dryers shipped during the period 20272056.

C. Conclusion
When considering new or amended energy conservation standards, the standards
that DOE adopts for any type (or class) of covered product must be designed to achieve
the maximum improvement in energy efficiency that the Secretary determines is
technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) In
127
The analysis period for TSL 3 (the Recommended TSL) is 20282057.
128
Id.
234
determining whether a standard is economically justified, the Secretary must determine
whether the benefits of the standard exceed its burdens by, to the greatest extent
practicable, considering the seven statutory factors discussed previously. (42 U.S.C.
6295(o)(2)(B)(i)) The new or amended standard must also result in significant
conservation of energy. (42 U.S.C. 6295(o)(3)(B))
For this direct final rule, DOE considered the impacts of amended standards for
consumer clothes dryers at each TSL, beginning with the maximum technologically
feasible level, to determine whether that level was economically justified. Where the
max-tech level was not justified, DOE then considered the next most efficient level and
undertook the same evaluation until it reached the highest efficiency level that is both
technologically feasible and economically justified and saves a significant amount of
energy.
To aid the reader as DOE discusses the benefits and/or burdens of each TSL,
tables in this section present a summary of the results of DOE’s quantitative analysis for
each TSL. In addition to the quantitative results presented in the tables, DOE also
considers other burdens and benefits that affect economic justification. These include the
impacts on identifiable subgroups of consumers who may be disproportionately affected
by a national standard and impacts on employment.
DOE also notes that the economics literature provides a wide-ranging discussion
of how consumers trade off upfront costs and energy savings in the absence of
government intervention. Much of this literature attempts to explain why consumers
235
appear to undervalue energy efficiency improvements. There is evidence that consumers
undervalue future energy savings as a result of (1) a lack of information; (2) a lack of
sufficient salience of the long-term or aggregate benefits; (3) a lack of sufficient savings
to warrant delaying or altering purchases; (4) excessive focus on the short-term, in the
form of inconsistent weighting of future energy cost savings relative to available returns
on other investments; (5) computational or other difficulties associated with the
evaluation of relevant tradeoffs; and (6) a divergence in incentives (for example, between
renters and owners, or builders and purchasers). Having less-than-perfect foresight and a
high degree of uncertainty about the future, consumers may trade off these types of
investments at a higher-than-expected rate between current consumption and uncertain
future energy cost savings.
It is important to recognize that while DOE is promulgating two separate
regulatory actions for energy efficiency standards for residential clothes washers and
consumer dryers, clothes washers and dryers are complementary products, and they are
sometimes sold and purchased together as joint goods. This type of consumer purchasing
behavior is not typical of DOE energy efficiency standards. These products are available
in a variety of combinations and the efficiency and/or product class of one product does
not restrict the efficiency and/or product class of the other. The efficiency levels are
independent of each other. Hence, DOE does not directly model the joint purchasing
decision of clothes washers and dryers in this rule. It is possible that if only one machine
fails, consumers could replace one machine or could replace both machines jointly. If
consumers replace both machines when one fails, aggregate lifecycle costs would be the
combination of impacts as presented in both final rules.
236
Consumers value a variety of attributes in consumer clothes dryers. These
attributes can factor into consumer purchasing decisions along with installation and
operating cost. For example, DOE understands certain consumers make purchasing
decisions on non-efficiency attributes such as color or other visual features such as
control panel layout, which may overlap with efficiency considerations related to and a
potential preference for mechanical over electronic controls.
One specific attribute related to the joint use of clothes washers and dryers worth
noting is the moisture content of clothes as consumers wash and dry them. DOE
recognizes that amended clothes washer standards could result in less total moisture
needing to be removed from the clothing in a dryer, whereas amended clothes dryer
standards could result in a less energy-intensive process for removing that moisture. As
explained on page 99, the amended dryer test procedure in appendix D2 includes
incoming RMC values (i.e., a starting lower moisture content for the load) that are more
representative of the resulting moisture content seen in high-efficiency clothes washers.
Due to the uniqueness of the Joint Recommendation where the clothes washer and dryer
proposals and compliance dates were aligned, the dryer rulemaking encompasses these
lower initial moisture values as a starting point for the energy use analysis, so the effect
of faster spin speeds resulting in less “wet” clothes is already captured by DOE. The
relative comparison of efficiency levels for a given product would remain the same, even
if the baseline energy consumption were adjusted due to an increase in efficiency in the
complementary product.
237
General considerations for consumer welfare and preferences as well as the
special cases of complementary goods are areas DOE plans to explore in a forthcoming
RFI related to the agency’s updates to its overall analytic framework.
In DOE’s current regulatory analysis, potential changes in the benefits and costs
of a regulation due to changes in consumer purchase decisions are included in two ways.
First, if consumers forego the purchase of a product in the standards case, this decreases
sales for product manufacturers, and the impact on manufacturers attributed to lost
revenue is included in the MIA. Second, DOE accounts for energy savings attributable
only to products actually used by consumers in the standards case; if a standard decreases
the number of products purchased by consumers, this decreases the potential energy
savings from an energy conservation standard. DOE provides estimates of shipments and
changes in the volume of product purchases in chapter 9 of the direct final rule TSD.
However, DOE’s current analysis does not explicitly control for heterogeneity in
consumer preferences, preferences across subcategories of products or specific features,
or consumer price sensitivity variation according to household income.
129
While DOE is not prepared at present to provide a fuller quantifiable framework
for estimating the benefits and costs of changes in consumer purchase decisions due to an
energy conservation standard, DOE is committed to developing a framework that can
support empirical quantitative tools for improved assessment of the consumer welfare
impacts of appliance standards. DOE has posted a paper that discusses the issue of
129

consumer welfare impacts of appliance energy conservation standards, and potential
enhancements to the methodology by which these impacts are defined and estimated in
the regulatory process.
130
1. Benefits and Burdens of TSLs Considered for Consumer Clothes Dryer Standards
Table V.42 and Table V.43 summarize the quantitative impacts estimated for each
TSL for consumer clothes dryers. The national impacts are measured over the lifetime of
consumer clothes dryers purchased in the 30-year period that begins in the anticipated
year of compliance with amended standards (2027–2056).
131
The energy savings,
emissions reductions, and value of emissions reductions refer to full-fuel-cycle results.
DOE is presenting monetized benefits of GHG emissions reductions in accordance with
the applicable Executive orders and DOE would reach the same conclusion presented in
this notice in the absence of the social cost of greenhouse gases, including the Interim
Estimates presented by the Interagency Working Group. The efficiency levels contained
in each TSL are described in section V.A of this document.

results include benefits to consumers which accrue after 2056 from the products shipped during the period
2027−2056 for all TSLs except for TSL 3 and 2057 from the products shipped during the period
2028−2057.
* Climate benefits are calculated using four different estimates of the SC-CO

4
and SC-N

O.
Together, these represent the global SC-GHG. For presentational purposes of this table, the climate benefits
associated with the average SC-GHG at a 3-percent discount rate are shown; however, DOE emphasizes
the importance and value of considering the benefits calculated using all four sets of SC-GHG estimates.
To monetize the benefits of reducing GHG emissions, this analysis uses the interim estimates presented in
the Technical Support Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates
Under Executive Order 13990 published in February 2021 by the IWG.
** Health benefits are calculated using benefit-per-ton values for NO

and SO
2
. DOE is currently only
monetizing (for NO

) PM
2.5
precursor health benefits and (for NO
X
) ozone precursor health
benefits, but will continue to assess the ability to monetize other effects such as health benefits from
reductions in direct PM
2.5
emissions. The health benefits are presented at real discount rates of 3 and 7
percent. See section IV.L of this document for more details.
Total and net benefits include consumer, climate, and health benefits. For presentation purposes, total and
net benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with 3-
percent discount rate.

DOE first considered TSL 6, which represents the max-tech efficiency level and
includes the design parameters of the most efficient products available on the market or
in working prototypes for all product classes. The max-tech design options include heat
pump technology for electric consumer clothes dryers and inlet air preheat technology for
gas consumer clothes dryers. DOE’s shipments analysis estimates approximately 1
percent of annual consumer clothes dryer shipments currently meet this level. TSL 6
would save an estimated 9.76 quads of energy, an amount DOE considers significant.
Under TSL 6, the NPV of consumer benefit would be $8.6 billion using a discount rate of
7 percent, and $30.5 billion using a discount rate of 3 percent.

benefits from reduced SO

emissions at TSL 6 is $8.7 billion using a 7-percent
discount rate and $20.9 billion using a 3-percent discount rate.

benefits from reduced GHG emissions, the estimated total NPV at TSL 6 is $28.2 billion.
Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL
6 is $62.2 billion. The estimated total NPV is provided for additional information;
however, DOE primarily relies upon the NPV of consumer benefits when determining
whether a standard level is economically justified.
At TSL 6, the average LCC impact on affected consumers is a savings of $41 for
electric standard, -$209 for electric compact (120V), -$230 for vented electric compact
(240V), $13 for vented gas standard, -$102 for ventless electric compact (240V), and -
$531 for ventless electric combination washer-dryer. The simple PBP is 6 years for
electric standard, 18 years for electric compact (120V), 20 years for vented electric
compact (240V), 5 years for vented gas standard, 11 years for ventless electric compact
(240V), and 46 years for ventless electric combination washer-dryer. The fraction of
consumers experiencing a net LCC cost is 63 percent for electric standard, 91 percent for
electric compact (120V), 93 percent for vented electric compact (240V), 69 percent for
vented gas standard, 59 percent for ventless electric compact (240V), and 95 percent for
ventless electric combination washer-dryer. Overall, across the product classes, the
majority of consumers will experience a net LCC cost, especially for senior households.
DOE estimated that more 72 percent of senior-only households will experience a net
LCC cost at TSL 6.
At TSL 6, the projected change in INPV ranges from a decrease of $1,511.1
million to a decrease of $361.9 million, corresponding to decreases of 71.4 percent and
17.1 percent, respectively. The loss in INPV is largely driven by industry conversion
243
costs as manufacturers work to redesign their portfolios of model offerings and retool
entire factories to comply with amended standards at this level. Industry conversion costs
could reach $1,516.9 million at this TSL.
Conversion costs at TSL 6 are significant, as nearly all existing consumer clothes
dryer models would need to be redesigned to meet the max-tech efficiencies.
Approximately 1 percent of industry shipments currently meet TSL 6. For the electric
clothes dryer product classes, manufacturers would need to implement heat pump
technology to meet max-tech levels. Out of the 19 OEMs that manufacture electric
consumer clothes dryers, nine OEMs offer heat pump models for the U.S. market. The
remaining 10 OEMs do not offer any models for the domestic market that utilize heat
pump technology. A standard that could only be met using heat pump technology would
require a total renovation of existing production facilities and would require most
manufacturers to design completely new clothes dryer platforms, as they would not be
able to maintain the resistive heating designs that currently dominate the U.S. electric
clothes dryer market. In interviews, several manufacturers expressed concern about a
potential shortage of products given the required scale of investment, redesign efforts,
and 3-year compliance timeline.
For gas consumer clothes dryers, manufacturers would need to implement inlet air
preheat technology along with other design options to meet the efficiency levels required
by TSL 6. Thus far, consumer clothes dryers with this technology and performance have
not been observed in consumer clothes dryers available on the consumer market.
Consumer clothes dryers with inlet air preheat designs have been observed only in
244
laboratory settings. In interviews, some manufacturers raised concerns about
implementing a relatively untested technology for the consumer market. There is very
little industry experience with inlet air preheat designs. Several manufacturers speculated
that implementing inlet air preheat technology would require a major overhaul of existing
production facilities and a significant amount of engineering time.
At this level, DOE estimates an 11-percent drop in shipments in the year the
standard takes effect compared to the no-new-standards case, as price-sensitive
consumers may forgo purchasing a new clothes dryer or rely on alternatives such as
repair or purchasing a used dryer due to the increased upfront cost of baseline models.
The Secretary concludes that at TSL 6 for consumer clothes dryers, the benefits of
energy savings, positive NPV of consumer benefits, emission reductions, and the
estimated monetary value of the emissions reductions would be outweighed by the
economic burden on many consumers, especially senior-only households, as well as the
impacts on manufacturers, including the potential for large conversion costs and
reduction in INPV.
TSL 6, representing the most efficient heat pump technology on the market,
would provide significant energy savings potential, as discussed. Despite the current and
potential future benefits of heat pump technology, the analysis at TSL 6 indicates that a
significant fraction of consumers, including low-income and senior-only households,
would experience a net cost given the current relatively high incremental cost of certain
consumer clothes dryers at the max-tech efficiency level. This is particularly pronounced
245
for electric standard clothes dryers, where the incremental production cost at the max-
tech efficiency level is comparable to the manufacturer production cost for the baseline
efficiency level. Consumers with existing electric standard clothes dryers below EL 4
(about 55 percent) and consumers with existing vented gas standard clothes dryers below
EL 3 (about 50 percent) are more likely to experience a net cost at TSL 6, given the
relatively modest decrease in operating costs compared to the high incremental installed
costs as represented by the weighted average LCC savings of $30. Few products
currently meet the efficiency levels required by TSL 6. DOE estimates that
approximately 1 percent of current shipments meet the max-tech efficiencies. At max-
tech, limited industry experience by certain manufacturers with the high-efficiency
design options, the large conversion costs to update facilities and product designs, and
expected drop in industry shipments would result in a reduction of INPV and a potential
shortage of products given the required scale of investment, redesign efforts, and time
constraints. Consequently, the Secretary has concluded that TSL 6 is not economically
justified.
DOE then considered TSL 5, which represents the maximum energy savings with
maximum positive NPV. TSL 5 corresponds to the max-tech level (EL 7), which
represents heat pump technology, for the electric standard product class, and the
efficiency levels corresponding to modulating (2-stage) heating technology in the electric
compact (120V) and inlet air preheat technology in the vented electric compact (240V)
product classes considered in this analysis. For the vented gas standard product class,
TSL 5 corresponds to the max-tech level (EL 4), which represents inlet air preheat
technology. TSL 5 would save an estimated 9.70 quads of energy, an amount DOE
246
considers significant. Under TSL 5, the NPV of consumer benefit would be $9.0 billion
using a discount rate of 7 percent, and $31.2 billion using a discount rate of 3 percent.

emissions, and the 3-percent discount rate case for climate

Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL
5 is $62.8 billion. The estimated total NPV is provided for additional information,
however DOE primarily relies upon the NPV of consumer benefits when determining
whether a standard level is economically justified.
At TSL 5, the average LCC impact on affected consumers is a savings of $41 for
electric standard, $66 for electric compact (120V), $22 for vented electric compact
(240V), $13 for vented gas standard, $99 for ventless electric compact (240V), and $10
for ventless electric combination washer-dryer. The simple PBP is 6 years for electric
standard, 2 years for electric compact (120V), 7 years for vented electric compact
247
(240V), 5 years for vented gas standard, 0.4 years for ventless electric compact (240V),
and zero years for ventless electric combination washer-dryer. The fraction of consumers
experiencing a net LCC cost is 63 percent for electric standard, 22 percent for electric
compact (120V), 61 percent for vented electric compact (240V), 69 percent for vented
gas standard, and zero percent for ventless electric compact (240V) and ventless electric
combination washer-dryer. Overall, across the product classes, approximately 63 percent
of consumers will experience a net LCC cost, especially for senior-only households. DOE
estimated that more than 71 percent of senior-only households will experience a net LCC
cost at TSL 5.
At TSL 5, the projected change in INPV ranges from a decrease of $1,435.5
million to a decrease of $314.6 million, corresponding to decreases of 67.9 percent and
14.9 percent, respectively. Industry conversion costs could reach $1,436.9 million at this
TSL.
DOE’s shipments analysis estimates approximately 2 percent of annual shipments
currently meet this level. At TSL 5, the efficiency levels and analyzed design options for
electric standard and vented gas standard dryers (which together account for
approximately 98 percent of industry shipments) are the same as at max-tech. Thus,
requiring heat pump technology for electric standard dryers and inlet air preheat for
vented gas standard dryers would result in similar conversion costs, reduction in INPV,
and drop in shipments as TSL 6.
248
At this level, DOE estimates a 11-percent drop in shipments in the year the
standard takes effect compared to the no-new-standards case, as price-sensitive
consumers may forgo purchasing a new clothes dryer or rely on alternatives such as
repair or purchasing a used dryer due to the increased upfront cost of baseline models.
The Secretary concludes that at TSL 5 for consumer clothes dryers, the benefits of
energy savings, positive NPV of consumer benefits, emission reductions, and the
estimated monetary value of the emissions reductions would be outweighed by the
economic burden on many consumers, especially senior-only households, as well as the
impacts on manufacturers, including the significant conversion costs and large potential
reduction in INPV. A significant fraction of electric standard clothes dryer consumers,
including low-income and senior-only households, would experience a net cost. This is
due to the high incremental cost of electric standard clothes dryers at the max-tech
efficiency level. Consumers with existing electric standard clothes dryers below EL 4 are
more likely to experience a net cost at TSL 5, given the relatively modest decrease in
operating costs compared to the high incremental installed costs. DOE estimates that
approximately 2 percent of shipments currently meet the efficiencies required by this
TSL. At TSL 5, the limited industry experience by certain manufacturers with the high-
efficiency design options, the large conversion costs to update facilities and product
designs, and expected drop in industry shipments would result in a reduction of INPV
and a potential shortage of products given the required scale of investment, redesign
efforts, and time constraints. Consequently, the Secretary has concluded that TSL 5 is
not economically justified.
249
DOE then considered TSL 4, which represents the maximum national energy
savings with simple PBP less than 4 years for each product class. TSL 4 corresponds to
the EL that represents inlet air preheat technology for the electric standard product class
considered in this analysis. For the electric compact (120V) and vented electric compact
(240V) product classes, TSL 4 corresponds to EL 4, which represents modulating (2-
stage) heating technology. For the vented gas standard product class, TSL 4 corresponds
to EL 3, which also represents modulating (2-stage) heating technology. TSL 4 would
save an estimated 3.52 quads of energy, an amount DOE considers significant. Under
TSL 4, the NPV of consumer benefit would be $8.4 billion using a discount rate of 7
percent, and $19.9 billion using a discount rate of 3 percent.

O. The estimated monetary value of the climate benefits from

reduced SO
2
and NO

emissions at TSL 4 is $3.6 billion using a 7-percent discount rate
and $8.2 million using a 3-percent discount rate.
Using a 7-percent discount rate for consumer benefits and costs, health benefits
from reduced SO

and NO
X
emissions, and the 3-percent discount rate case for climate
benefits from reduced GHG emissions, the estimated total NPV at TSL 4 is $16.3 billion.
Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL
4 is $32.4 billion. The estimated total NPV is provided for additional information;
250
however, DOE primarily relies upon the NPV of consumer benefits when determining
whether a standard level is economically justified.
At TSL 4, the average LCC impact on affected consumers is a savings of $101 for
electric standard, $66 for electric compact (120V), $90 for vented electric compact
(240V), $102 for vented gas standard, $99 for ventless electric compact, and $10 for
ventless electric combination washer-dryer. The simple PBP is 2 years for electric
standard, 2 years for electric compact (120V), 2 years for vented electric compact
(240V), 2 years for vented gas standard, 0.4 years for ventless electric compact (240V),
and 0 years for ventless electric combination washer-dryer. The fraction of consumers
experiencing a net LCC cost is 48 percent for electric standard, 22 percent for electric
compact (120V), 13 percent for vented electric compact (240V), 7 percent for vented gas
standard, and zero percent for ventless electric compact (240V) and ventless electric
combination washer-dryer. Overall, across the product classes, approximately 40 percent
of consumers will experience a net LCC cost, especially for senior households. DOE
estimated that about 45 percent of senior-only households will experience a net LCC cost
at TSL 4.
At TSL 4, the projected change in INPV ranges from a decrease of $613.5 million
to a decrease of $390.6 million, corresponding to decreases of 29.0 percent and 18.5
percent, respectively. Industry conversion costs could reach $667.5 million at this TSL.
At TSL 4, the majority of consumer clothes dryer models would need to be
redesigned to meet the efficiency levels required. DOE’s shipments analysis estimates
251
approximately 15 percent of current shipments meet this level. For electric standard
dryers, the design options include implementing inlet air preheat and other features. As
previously noted, electric standard dryers account for approximately 81 percent of total
shipments. At the current time, there is very little industry experience with inlet air
preheat designs. Currently, DOE is not aware of any consumer clothes dryers on the
market utilizing this design option. DOE’s shipments analysis estimates that
approximately 7 percent of electric standard shipments currently meet the efficiency
required by TSL 4. Implementing inlet air preheat for electric standard dryers would
represent a major overhaul of existing product lines and manufacturing facilities. This
change would necessitate significant investments in new equipment and tooling. Product
conversion costs would be necessary for designing, prototyping, and testing new or
updated platforms.
For vented gas standard clothes dryers, the analyzed design option at TSL 4
includes modulating (2-stage) heat technology, among other design options. Out of the
nine OEMs that manufacture vented gas standard clothes dryers, eight offer products that
meet the efficiencies required at TSL 4. DOE does not believe that there are any
substantive barriers to modulating (2-stage) heating technology. Capital conversion costs
would be necessary as manufacturers increase tooling for 2-stage heating systems.
Product conversion costs would be necessary for cost-optimizing and testing new designs
for a market with amended standards.
At this level, DOE does not expect a notable drop in shipments in the year the
standard takes effect.
252
The Secretary concludes that at TSL 4 for consumer clothes dryers, the benefits of
energy savings, positive NPV of consumer benefits, emission reductions, and the
estimated monetary value of the emissions reductions would be outweighed by the
economic burden on many consumers, especially senior-only households, as well as the
impacts on manufacturers, including the conversion costs and profit margin impacts that
could result in a large reduction in INPV. A significant fraction of electric standard
clothes dryer consumers, including senior-only households, would experience a net cost.
This is due to the high incremental cost of electric standard clothes dryers at the inlet air
preheat technology efficiency level. Consumers with existing electric standard clothes
dryers below EL 4 are more likely to experience a net cost at TSL 4, given the relatively
modest decrease in operating costs compared to the high incremental installed costs. For
electric standard dryers, DOE estimates that approximately 7 percent of shipments
currently meet the efficiency level required by this TSL. At TSL 4, the limited industry
experience of electric standard dryer manufacturers with inlet air preheat technology and
the large conversion costs to update facilities and product designs, would result in a large
reduction of INPV. Consequently, the Secretary has concluded that TSL 4 is not
economically justified.
DOE then considered the Recommended TSL, which represents a set of
intermediate efficiency levels between those designated in TSL 2 and TSL 4 and
corresponds to the current ENERGY STAR efficiency levels for the electric standard and
vented gas standard product classes, which represent approximately 98 percent of the
market. The Recommended TSL corresponds to the EL that represents modulating (2-
stage) heating technology for the electric standard and electric compact (120V) product
253
classes. For the vented gas standard product class, the Recommended TSL corresponds
to EL 3, which also represents modulating (2-stage) heating technology. For the vented
gas compact product class, the Recommended TSL corresponds to baseline CEF
D2
. For
the electric compact (240V) product classes, the Recommended TSL corresponds to EL 2
for vented consumer clothes dryers, which represents a model with an optimized heating
system and EL 1 for ventless consumer clothes dryers, which represents a baseline model
with a more advanced automatic termination control system. For the ventless electric
combination washer-dryer product class, the Recommended TSL corresponds to EL 1,
which represents a baseline model with high-speed spin technology. The Recommended
TSL would save an estimated 2.66 quads of energy, an amount DOE considers
significant. Under the Recommended TSL, the NPV of consumer benefit would be $9.23
billion using a discount rate of 7 percent, and $20.08 billion using a discount rate of 3
percent.
The cumulative emissions reductions at the Recommended TSL are 57.1 Mt of

O. The estimated monetary value of
the climate benefits from reduced GHG emissions (associated with the average SC-GHG

the health benefits from reduced SO
2
and NO

emissions at TSL 3 is $2.6 billion using a
7-percent discount rate and $6.3 billion using a 3-percent discount rate.
Using a 7-percent discount rate for consumer benefits and costs, health benefits
from reduced SO

and NO
X
emissions, and the 3-percent discount rate case for climate
254
benefits from reduced GHG emissions, the estimated total NPV at the Recommended
TSL is $15.2 billion. Using a 3-percent discount rate for all benefits and costs, the
estimated total NPV at the Recommended TSL is $29.7 billion. The estimated total NPV
is provided for additional information; however, DOE primarily relies upon the NPV of
consumer benefits when determining whether a standard level is economically justified.
At the Recommended TSL, the average LCC impact on affected consumers is a
savings of $252 for electric standard, $66 for electric compact (120V), $90 for vented
electric compact (240V), $102 for vented gas standard, $99 for ventless electric compact,
and $11 for ventless electric combination washer-dryer. The simple PBP is 1 year for the
largest product class (electric standard), 2 years for electric compact (120V), 2 years for
vented electric compact (240V), 2 years for vented gas standard, 0.4 years for ventless
electric compact (240V), and 0 years for ventless electric combination washer-dryer. The
fraction of consumers experiencing a net LCC cost is 1 percent for electric standard, 21
percent for PC 2, 12 percent for vented electric compact (240V), 7 percent for vented gas
standard, and zero percent for ventless electric compact (240V) and ventless electric
combination washer-dryer. Overall, across the product classes, approximately 2 percent
of consumers, including low-income and senior-only households, will experience a net
LCC cost.
At the Recommended TSL, the projected change in INPV ranges from a decrease
of $144.2 million to a decrease of $119.7 million, corresponding to decreases of 6.8
percent and 5.7 percent, respectively. Industry conversion costs could reach $180.7
million at this TSL.
255
DOE expects that some existing consumer clothes dryer models would need to be
redesigned to meet the Recommended TSL efficiencies, but there are a wide range of
available models for vented electric standard dryers due to participation in the ENERGY
STAR program. DOE’s shipments analysis estimates approximately 48 percent of annual
shipments currently meet this level. For electric standard, electric compact (120V),
vented electric compact (240V), and vented gas standard clothes dryers, which account
for approximately 99 percent of total annual shipments, the design options include
implementing electronic controls, optimized heating systems, more advanced automatic
termination controls, and modulating (2-stage) heat. Of the 19 electric dryer OEMs, 14
offer products at or above the efficiencies required for the electric dryer product classes at
the Recommended TSL. Out of the nine OEMs that manufacture vented gas standard
clothes dryers, eight offer products that meet the efficiencies required at the
Recommended TSL. Capital conversion costs may be necessary as manufacturers
increase tooling for 2-stage heating systems. Manufacturers may choose to further cost-
optimize and test new designs as a result of the standards, but DOE believes some of this
has already occurred in response to ENERGY STAR. DOE does not expect any drop in
shipments in the year the standard takes effect.
For all TSLs considered in this direct final rule—except for the Recommended
TSL—DOE is bound by the 3-year lead time requirements in EPCA when determining
compliance dates (i.e., compliance with amended standards required in 2027). For the
Recommended TSL, DOE’s analysis utilized the March 1, 2028, compliance date
specified in the Joint Agreement as it was an integral part of the multi-product joint
recommendation. A 2028 compliance year provides manufacturers additional flexibility
256
to spread capital requirements, engineering resources, and conversion activities over a
longer period of time depending on the individual needs of each manufacturer.
At the Recommended TSL, DOE’s data demonstrate no negative impact on
consumer utility for consumer clothes dryers. In addition, the second joint statement from
the same group of stakeholders that submitted the Joint Agreement states that DOE’s test
data show, and industry experience agrees, that the recommended standard level for
consumer clothes dryers will not result in significant differences in cycle time and will
adequately dry clothes.
132
Based on the information available, DOE concludes that no
lessening of product utility or performance would occur at the Recommended TSL.
After considering the analysis and weighing the benefits and burdens, the
Secretary has concluded that a standard set at the Recommended TSL for consumer
clothes dryers would result in the maximum improvement in energy efficiency that is
technologically feasible and economically justified and also result in the significant
conservation of energy. At this TSL, the average LCC savings for all consumer clothes
dryer product classes are positive. An estimated weighted average of 2 percent of
consumer clothes dryer consumers would experience a net cost. The FFC national energy
savings are significant and the NPV of consumer benefits is positive using both a 3-
percent and 7-percent discount rate. Notably, the benefits to consumers vastly outweigh
the cost to manufacturers. At the Recommended TSL, the NPV of consumer benefits,
even measured at the more conservative discount rate of 7 percent, is over 64 times
132

0058.
257
higher than the maximum estimated manufacturers’ loss in INPV. The positive LCC
savings—a different way of quantifying consumer benefits—reinforces this conclusion.
The standard levels at the Recommended TSL are economically justified even without
weighing the estimated monetary value of emissions reductions. When those emissions
reductions are included—representing $3.3 billion in climate benefits (associated with the
average SC-GHG at a 3-percent discount rate), and $6.3 billion (using a 3-percent
discount rate) or $2.6 billion (using a 7-percent discount rate) in health benefitsthe
rationale becomes stronger still.
As stated, DOE conducts the walk-down analysis to determine the TSL that
represents the maximum improvement in energy efficiency that is technologically
feasible and economically justified as required under EPCA. The walk-down is not a
comparative analysis, as a comparative analysis would result in the maximization of net
benefits instead of energy savings that are technologically feasible and economically
justified, which would be contrary to the statute. 86 FR 70892, 70908. Although DOE
has not conducted a comparative analysis to select the amended energy conservation
standards, DOE notes that as compared to TSL 6, TSL 5, and TSL 4, the Recommended
TSL has higher average LCC savings, smaller percentages of consumers experiencing a
net cost, a lower maximum decrease in INPV, and lower manufacturer conversion costs.
Although DOE considered amended standard levels for consumer clothes dryers
by grouping the efficiency levels for each product class into TSLs, DOE evaluates all
analyzed efficiency levels in its analysis. Accordingly, the Secretary has concluded that
the Recommended TSL would offer the maximum improvement in efficiency that is

technologically feasible and economically justified and would result in the significant
conservation of energy. For electric standard and vented gas standard consumer clothes
dryers, which account for approximately 98 percent of U.S. shipments, requiring
efficiency levels above the levels required by the Recommended TSL result in a large
percentage of consumers experiencing a net LCC cost, in addition to significant
manufacturer impacts and reductions in INPV. Additionally, for consumer clothes
dryers, most manufacturers offer products that can meet the Recommended TSL across
both electric and gas consumer clothes dryers. In addition, the Recommended TSL
corresponds to the current ENERGY STAR levels for electric standard and vented gas
standard clothes dryers, which have significant market share and manufacturer support
due to their promotion over the past couple of years as a voluntary energy efficiency
program. The adoption of standards, if finalized, at this TSL may encourage ENERGY
STAR to further consider more efficient levels for dryers in the year leadings up to the
compliance of date of the standard, which would in turn likely spur additional market
introductions of consumer clothes dryers with heat pump technology, foster maturation of
the technology and downward price trends, and further support differentiation within the
dryer market for energy efficient products.
For electric and vented gas standard
consumer clothes dryers, the Recommended TSL is comprised of EL 4 and EL 3,
respectively, resulting in higher LCC savings, a significant reduction in the number of
consumers experiencing a net cost, a lower maximum decrease in INPV, and lower
conversion costs to the point where DOE has concluded they are economically justified,
as discussed for the Recommended TSL in the preceding paragraphs.
259
Therefore, based on the previous considerations, DOE adopts the energy
conservation standards for consumer clothes dryers at the Recommended TSL.
While DOE considered each potential TSL under the criteria laid out in 42 U.S.C.
6295(o) as discussed above, DOE notes that the Recommended TSL for consumer
clothes dryers adopted in this direct final rule is part of a multi-product Joint Agreement
covering six rulemakings (residential clothes washers; consumer clothes dryers;
consumer conventional cooking products; dishwashers; refrigerators, refrigerator-
freezers, and freezers; and miscellaneous refrigeration products). The signatories
indicated that the Joint Agreement for the six rulemakings should be considered as a joint
statement of recommended standards, to be adopted in its entirety. As discussed in
section V.B.2.e of this document, many consumer clothes dryer OEMs also manufacture
residential clothes dryers; consumer conventional cooking products; dishwashers;
refrigerators, refrigerator-freezers, and freezers; and miscellaneous refrigeration products.
Therefore, there are potential integrated benefits to the Joint Agreement. Rather than
requiring compliance with five amended standards in a single year (2027),
133
the
negotiated multi-product Joint Agreement staggers the compliance dates for the five
amended standards over a 4-year period (2027–2030). In response to the August 2022
NOPR, AHAM expressed concerns about the timing of ongoing home appliance
rulemakings. Specifically, AHAM commented that there are a number of ongoing
regulations that impact consumer clothes dryer manufacturers. (AHAM, No. 46 at p. 13)
133
The analyses for residential clothes washers (88 FR 13520); consumer clothes dryers (87 FR 51734);
consumer conventional cooking products (88 FR 6818); dishwashers (88 FR 32514); and refrigerators,
refrigerator-freezers, and freezers (88 FR 12452) utilized a 2027 compliance year for analysis at the
proposed rule stage. Miscellaneous refrigeration products (88 FR 12452) utilized a 2029 compliance year
for the NOPR analysis.
260
AHAM has submitted similar comments to other ongoing home appliance
rulemakings.
134
As AHAM is a key signatory of the Joint Agreement, DOE understands
that the compliance dates recommended in the Joint Agreement would help reduce
cumulative regulatory burden. These compliance dates help relieve concern on the part of
some manufacturers about their ability to allocate sufficient resources to comply with
multiple concurrent amended standards and about the need to align compliance dates for
products that are typically designed or sold as matched pairs. The Joint Agreement also
provides additional years of regulatory certainty for manufacturers and their suppliers.
For residential clothes washers and consumer clothes dryers specifically, aligned
compliance dates would help reduce cumulative regulatory burden for the 13 OEMs that
manufacture both residential clothes washers and consumer clothes dryers. In response to
the August 2022 NOPR, AHAM commented that laundry products (RCWs and consumer
clothes dryers) are designed and used in pairs. (AHAM, No. 46 at p. 10) AHAM stated
that an additional design cycle for clothes washers and/or clothes dryers may be
necessary if the effective compliance dates for the two products were out of sync. AHAM
further stated that coordinated compliance dates would greatly reduce burden on
manufacturers and retailers. (Id.)
134
AHAM has submitted written comments regarding cumulative regulatory burden for the other five
rulemakings included in the multi-product Joint Agreement. AHAM’s written comments on cumulative
regulatory burden are available at: www.regulations.gov/comment/EERE-2017-BT-STD-0014-0464 (pp.
4144) for residential clothes washers; www.regulations.gov/comment/EERE-2014-BT-STD-0005-2285
(pp. 4447) for consumer conventional cooking products; www.regulations.gov/comment/EERE-2019-BT-
STD-0039-0051 (pp. 2124) for dishwashers; www.regulations.gov/comment/EERE-2017-BT-STD-0003-
0069 (pp. 2022) for refrigerators, refrigerator-freezers, and freezers; and
www.regulations.gov/comment/EERE-2020-BT-STD-0039-0031 (pp. 1215) for miscellaneous
refrigeration products.

NEEA, the Joint Commenters, and Samsung supported DOE's proposed TSL 3,
which aligns with the Recommended TSL in this direct final rule, given the national
energy savings, life-cycle cost savings, and reasonable manufacturer impacts. According
to the Joint Commenters, TSL 3 provides large cost savings for all consumer groups,
including low-income households. Samsung supported DOE's proposed TSL 3 and
believes the test sample adequately represents the current marketplace. (NEEA, No. 45 at
p. 2; Joint Commenters, No. 51 at p. 2; Samsung, No. 54 at p. 2)
NYSERDA also supported DOE's proposal in the August 2022 NOPR and urged
expedient adoption of the amended standards given significant LCC savings, reasonable
payback periods, significant GHG emissions reductions, energy savings, and monetary
benefits for consumers in New York and beyond, and the aging out of a significant
portion of the installed dryer stock in New York. According to the 2019 New York
Residential Building Stock Assessment, 49 percent of New York consumer clothes dryers
262
are over 10 years old, and another 81 percent are 5 years or older. NYSERDA stated that
based on DOE’s assumption of a product lifetime average of 14 years, a significant
number of dryers in New York will be due for replacement around the time of the new
standard, but only if DOE finalizes this standard promptly. (NYSERDA, No. 48 at pp. 1–
2)
While the California IOUs supported DOE’s conclusion that TSL 3 represented
an economically justified and technologically feasible efficiency level achieving
significant energy savings, the California IOUs requested that DOE clarify the supporting
data that led to the conclusion that TSL 4 was not economically justified. The California
IOUs urged DOE to adopt TSL 3 at the earliest opportunity so that consumers may obtain
the significant savings provided from this level. (California IOUs, No. 50 at pp. 1–2)
As previously stated, TSL 4 is not economically justified. Nearly 50 percent of
electric standard clothes dryer users, including over 53 percent of senior-only households,
would experience a net cost. This can be attributed to the high incremental cost of electric
standard dryers with the inlet air preheat technology efficiency level. Moreover, the
industry conversion costs for implementing TSL 4 could amount to $668 million,
resulting in a substantial decrease in the manufacturer's INPV. In addition, there is very
little industry experience with inlet air preheat designs. Currently, DOE is not aware of
any consumer clothes dryers on the market utilizing this design option. DOE’s shipments
analysis estimates that approximately 7 percent of electric standard shipments currently
meet the efficiency required by TSL 4. Implementing inlet air preheat for electric
263
standard dryers would represent a major overhaul of existing product lines and
manufacturing facilities.
2. Annualized Benefits and Costs of the Adopted Standards
The benefits and costs of the adopted standards can also be expressed in terms of
annualized values. The annualized net benefit is (1) the annualized national economic
value (expressed in 2022$) of the benefits from operating products that meet the adopted
standards (consisting primarily of operating cost savings from using less energy), minus
increases in product purchase costs, and (2) the annualized monetary value of the climate
and health benefits.
Table V.45 shows the annualized values for consumer clothes dryers under the
Recommended TSL, expressed in 2022$. The results under the primary estimate are as
follows.
Using a 7-percent discount rate for consumer benefits and costs and NO
X
and SO
2
reductions, and the 3-percent discount rate case for GHG social costs, the estimated cost
of the adopted standards for consumer clothes dryers is $60.0 million per year in
increased equipment installed costs, while the estimated annual benefits are $971.4
million from reduced equipment operating costs, $185.5 million in GHG reductions, and
$259.9 million from reduced NO
X
and SO
2
emissions. In this case, the net benefit
amounts to $1,357 million per year.
264
Using a 3-percent discount rate for all benefits and costs, the estimated cost of the
adopted standards for consumer clothes dryers is $57.2 million per year in increased
equipment costs, while the estimated annual benefits are $1,177 million in reduced
operating costs, $185.5 million from GHG reductions, and $349.4 million from reduced
NO
X
and SO
2
emissions. In this case, the net benefit amounts to $1,654 million per year.

Note: This table presents the costs and benefits associated with consumer clothes dryers shipped in 2028−2057. These
results include benefits to consumers which accrue after 2057 from the products shipped in 2028−2057. The Primary,
Low-Net-Benefits, and High-Net-Benefits estimates utilize projections of energy prices from the AEO2023 Reference
case, Low Economic Growth case, and High Economic Growth case, respectively. In addition, incremental equipment
265
costs reflect a medium decline rate in the Primary Estimate, a constant rate in the Low-Net-Benefits Estimate, and a
high decline rate in the High-Net-Benefits Estimate. The methods used to derive projected price trends are explained in
sections IV.F.1 and IV.H.3 of this document. Note that the Benefits and Costs may not sum to the Net Benefits due to
rounding.
* Climate benefits are calculated using four different estimates of the global SC-GHG (see section IV.L of this
document). For presentational purposes of this table, the climate benefits associated with the average SC-GHG at a 3-
percent discount rate are shown, but DOE does not have a single central SC-GHG point estimate, and it emphasizes the
importance and value of considering the benefits calculated using all four sets of SC-GHG estimates. To monetize the
benefits of reducing GHG emissions, this analysis uses the interim estimates presented in the Technical Support
Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates Under Executive Order 13990
published in February 2021 by the IWG.
** Health benefits are calculated using benefit-per-ton values for NO
X
and SO
2
. DOE is currently only monetizing (for
SO
2
and NO
X
) PM
2.5
precursor health benefits and (for NO
X
) ozone precursor health benefits, but will continue to
assess the ability to monetize other effects such as health benefits from reductions in direct PM
2.5
emissions. See
section IV.L of this document for more details.
Total benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with 3-percent
discount rate, but DOE does not have a single central SC-GHG point estimate.
‡ Costs include incremental equipment costs as well as installation costs.
‡‡ Operating Cost Savings are calculated based on the life cycle costs analysis and national impact analysis as
discussed in detail below. See sections IV.F and IV.H of this document. DOE’s NIA includes all impacts (both costs
and benefits) along the distribution chain beginning with the increased costs to the manufacturer to manufacture the
product and ending with the increase in price experienced by the consumer. DOE also separately conducts a detailed
analysis on the impacts on manufacturers (the MIA). See section IV.J of this document and chapter 12 of the direct
final rule TSD. In the detailed MIA, DOE models manufacturers’ pricing decisions based on assumptions regarding
investments, conversion costs, cashflow, and margins. The MIA produces a range of impacts, which is the rule’s
expected impact on the INPV. The change in INPV is the present value of all changes in industry cash flow, including
changes in production costs, capital expenditures, and manufacturer profit margins. The annualized change in INPV is
calculated using the industry weighted average cost of capital value of 7.5 percent that is estimated in the manufacturer
impact analysis (see chapter 12 of the direct final rule TSD for a complete description of the industry weighted average
cost of capital). For consumer clothes dryers, those values are -$12 million to -$10 million. DOE accounts for that
range of likely impacts in analyzing whether a TSL is economically justified. See section V.C of this document. DOE is
presenting the range of impacts to the INPV under two manufacturer markup scenarios: the Preservation of Gross
Margin scenario, which is the manufacturer markup scenario used in the calculation of Consumer Operating Cost
Savings in this table, and the Preservation of Operating Profit scenario, where DOE assumed manufacturers would not
be able to increase per-unit operating profit in proportion to increases in manufacturer production costs. DOE includes
the range of estimated annualized change in INPV in the above table, drawing on the MIA explained further in chapter
12 of the direct final rule TSD, to provide additional context for assessing the estimated impacts of this direct final rule
to society, including potential changes in production and consumption, which is consistent with OMB’s Circular A-4
and E.O. 12866. If DOE were to include the INPV into the annualized net benefit calculation for this direct final rule,
the annualized net benefits, using the primary estimate, would range from $1,642 million to $,1644 million at 3-percent
discount rate and would range from $1,345 million to $1,347 million at 7-percent discount rate. Parentheses () indicate
negative values.
VI. Procedural Issues and Regulatory Review
A. Review Under Executive Orders 12866, 13563 and 14094
Executive Order (“E.O.”) 12866, “Regulatory Planning and Review,” as
supplemented and reaffirmed by E.O. 13563, “Improving Regulation and Regulatory
266
Review,” 76 FR 3821 (Jan. 21, 2011) and amended by E.O. 14094, “Modernizing
Regulatory Review,” 88 FR 21879 (April 11, 2023), requires agencies, to the extent
permitted by law, to (1) propose or adopt a regulation only upon a reasoned
determination that its benefits justify its costs (recognizing that some benefits and costs
are difficult to quantify); (2) tailor regulations to impose the least burden on society,
consistent with obtaining regulatory objectives, taking into account, among other things,
and to the extent practicable, the costs of cumulative regulations; (3) select, in choosing
among alternative regulatory approaches, those approaches that maximize net benefits
(including potential economic, environmental, public health and safety, and other
advantages; distributive impacts; and equity); (4) to the extent feasible, specify
performance objectives, rather than specifying the behavior or manner of compliance that
regulated entities must adopt; and (5) identify and assess available alternatives to direct
regulation, including providing economic incentives to encourage the desired behavior,
such as user fees or marketable permits, or providing information upon which choices can
be made by the public. DOE emphasizes as well that E.O. 13563 requires agencies to use
the best available techniques to quantify anticipated present and future benefits and costs
as accurately as possible. In its guidance, the Office of Information and Regulatory
Affairs (“OIRA”) in the Office of Management and Budget (“OMB”) has emphasized
that such techniques may include identifying changing future compliance costs that might
result from technological innovation or anticipated behavioral changes. For the reasons
stated in the preamble, this final regulatory action is consistent with these principles.
Section 6(a) of E.O. 12866 also requires agencies to submit “significant
regulatory actions” to OIRA for review. OIRA has determined that this final regulatory
267
action constitutes a “significant regulatory action” within the scope of section 3(f) of E.O.
12866. DOE has provided to OIRA an assessment, including the underlying analysis, of
benefits and costs anticipated from the final regulatory action, together with, to the extent
feasible, a quantification of those costs; and an assessment, including the underlying
analysis, of costs and benefits of potentially effective and reasonably feasible alternatives
to the planned regulation, and an explanation why the planned regulatory action is
preferable to the identified potential alternatives. These assessments are summarized in
this preamble and further detail can be found in the technical support document for this
rulemaking.
B. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires preparation of an
initial regulatory flexibility analysis (“IRFA”) and a final regulatory flexibility analysis
(“FRFA”) for any rule that by law must be proposed for public comment, unless the
agency certifies that the rule, if promulgated, will not have a significant economic impact
on a substantial number of small entities. As required by E.O. 13272, “Proper
Consideration of Small Entities in Agency Rulemaking,” 67 FR 53461 (Aug. 16, 2002),
DOE published procedures and policies on February 19, 2003, to ensure that the potential
impacts of its rules on small entities are properly considered during the rulemaking
process. 68 FR 7990. DOE has made its procedures and policies available on the Office
of the General Counsel’s website (www.energy.gov/gc/office-general-counsel).
DOE is not obligated to prepare a regulatory flexibility analysis for this
rulemaking because there is not a requirement to publish a general notice of proposed
268
rulemaking under the Administrative Procedure Act. See 5 U.S.C. 601(2), 603(a). As
discussed previously, DOE has determined that the Joint Agreement meets the necessary
requirements under EPCA to issue this direct final rule for energy conservation standards
for consumer clothes dryers under the procedures in 42 U.S.C. 6295(p)(4). DOE notes
that the NOPR for energy conservation standards for consumer clothes dryers published
elsewhere in this issue of the Federal Register contains a regulatory flexibility analysis.
C. Review Under the Paperwork Reduction Act
Manufacturers of consumer clothes dryers must certify to DOE that their products
comply with any applicable energy conservation standards. In certifying compliance,
manufacturers must test their products according to the DOE test procedures for
consumer clothes dryers, including any amendments adopted for those test procedures.
DOE has established regulations for the certification and recordkeeping requirements for
all covered consumer products and commercial equipment, including consumer clothes
dryers. (See generally 10 CFR part 429.) The collection-of-information requirement for
the certification and recordkeeping is subject to review and approval by OMB under the
Paperwork Reduction Act (“PRA”). This requirement has been approved by OMB under
OMB control number 1910-1400. Public reporting burden for the certification is
estimated to average 35 hours per response, including the time for reviewing instructions,
searching existing data sources, gathering and maintaining the data needed, and
completing and reviewing the collection of information.
269
Notwithstanding any other provision of the law, no person is required to respond
to, nor shall any person be subject to a penalty for failure to comply with, a collection of
information subject to the requirements of the PRA, unless that collection of information
displays a currently valid OMB Control Number.
D. Review Under the National Environmental Policy Act of 1969
Pursuant to the National Environmental Policy Act of 1969 (“NEPA”), DOE has
analyzed this rule in accordance with NEPA and DOE’s NEPA implementing regulations
(10 CFR part 1021). DOE has determined that this rule qualifies for categorical
exclusion under 10 CFR part 1021, subpart D, appendix B5.1 because it is a rulemaking
that establishes energy conservation standards for consumer products or industrial
equipment, none of the exceptions identified in B5.1(b) apply, no extraordinary
circumstances exist that require further environmental analysis, and it meets the
requirements for application of a categorical exclusion. See 10 CFR 1021.410.
Therefore, DOE has determined that promulgation of this rule is not a major Federal
action significantly affecting the quality of the human environment within the meaning of
NEPA, and does not require an environmental assessment or an environmental impact
statement.
E. Review Under Executive Order 13132
E.O. 13132, “Federalism,” 64 FR 43255 (Aug. 10, 1999), imposes certain
requirements on Federal agencies formulating and implementing policies or regulations
that preempt State law or that have federalism implications. The Executive order requires
agencies to examine the constitutional and statutory authority supporting any action that
270
would limit the policymaking discretion of the States and to carefully assess the necessity
for such actions. The Executive order also requires agencies to have an accountable
process to ensure meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications. On March 14,
2000, DOE published a statement of policy describing the intergovernmental consultation
process it will follow in the development of such regulations. 65 FR 13735. DOE has
examined this rule and has determined that it would not have a substantial direct effect on
the States, on the relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of government.
EPCA governs and prescribes Federal preemption of State regulations as to energy
conservation for the products that are the subject of this direct final rule. States can
petition DOE for exemption from such preemption to the extent, and based on criteria, set
forth in EPCA. (42 U.S.C. 6297) Therefore, no further action is required by Executive
Order 13132.
F. Review Under Executive Order 12988
With respect to the review of existing regulations and the promulgation of new
regulations, section 3(a) of E.O. 12988, “Civil Justice Reform,” imposes on Federal
agencies the general duty to adhere to the following requirements: (1) eliminate drafting
errors and ambiguity, (2) write regulations to minimize litigation, (3) provide a clear legal
standard for affected conduct rather than a general standard, and (4) promote
simplification and burden reduction. 61 FR 4729 (Feb. 7, 1996). Regarding the review
required by section 3(a), section 3(b) of E.O. 12988 specifically requires that Executive
agencies make every reasonable effort to ensure that the regulation (1) clearly specifies
271
the preemptive effect, if any, (2) clearly specifies any effect on existing Federal law or
regulation, (3) provides a clear legal standard for affected conduct while promoting
simplification and burden reduction, (4) specifies the retroactive effect, if any, (5)
adequately defines key terms, and (6) addresses other important issues affecting clarity
and general draftsmanship under any guidelines issued by the Attorney General. Section
3(c) of E.O. 12988 requires Executive agencies to review regulations in light of
applicable standards in section 3(a) and section 3(b) to determine whether they are met or
it is unreasonable to meet one or more of them. DOE has completed the required review
and determined that, to the extent permitted by law, this direct final rule meets the
relevant standards of E.O. 12988.
G. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (“UMRA”) requires each
Federal agency to assess the effects of Federal regulatory actions on State, local, and
Tribal governments and the private sector. Public Law 104-4, Sec. 201 (codified at 2
U.S.C. 1531). For a regulatory action likely to result in a rule that may cause the
expenditure by State, local, and Tribal governments, in the aggregate, or by the private
sector of $100 million or more in any one year (adjusted annually for inflation), section
202 of UMRA requires a Federal agency to publish a written statement that estimates the
resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a),
(b)) The UMRA also requires a Federal agency to develop an effective process to permit
timely input by elected officers of State, local, and Tribal governments on a “significant
intergovernmental mandate,” and requires an agency plan for giving notice and
opportunity for timely input to potentially affected small governments before establishing
272
any requirements that might significantly or uniquely affect them. On March 18, 1997,
DOE published a statement of policy on its process for intergovernmental consultation
under UMRA. 62 FR 12820. DOE’s policy statement is also available at
www.energy.gov/sites/prod/files/gcprod/documents/umra_97.pdf.
DOE has concluded that this direct final rule may require expenditures of $100
million or more in any one year by the private sector. Such expenditures may include
(1) investment in research and development and in capital expenditures by consumer
clothes dryer manufacturers in the years between the direct final rule and the compliance
date for the new standards and (2) incremental additional expenditures by consumers to
purchase higher efficiency consumer clothes dryers starting at the compliance date for the
applicable standard.
Section 202 of UMRA authorizes a Federal agency to respond to the content
requirements of UMRA in any other statement or analysis that accompanies the direct
final rule. (2 U.S.C. 1532(c)) The content requirements of section 202(b) of UMRA
relevant to a private sector mandate substantially overlap the economic analysis
requirements that apply under section 325(o) of EPCA and Executive Order 12866. This
SUPPLEMENTARY INFORMATION section and the TSD for this direct final rule
respond to those requirements.
Under section 205 of UMRA, the Department is obligated to identify and consider
a reasonable number of regulatory alternatives before promulgating a rule for which a
written statement under section 202 is required. (2 U.S.C. 1535(a)) DOE is required to
273
select from those alternatives the most cost-effective and least burdensome alternative
that achieves the objectives of the rule unless DOE publishes an explanation for doing
otherwise, or the selection of such an alternative is inconsistent with law. As required by
42 U.S.C. 6295(m), this direct final rule establishes amended energy conservation
standards for consumer clothes dryers that are designed to achieve the maximum
improvement in energy efficiency that DOE has determined to be both technologically
feasible and economically justified, as required by 6295(o)(2)(A) and 6295(o)(3)(B). A
full discussion of the alternatives considered by DOE is presented in chapter 17 of the
TSD for this direct final rule.
H. Review Under the Treasury and General Government Appropriations Act, 1999
Section 654 of the Treasury and General Government Appropriations Act, 1999
(Pub. L. 105-277) requires Federal agencies to issue a Family Policymaking Assessment
for any rule that may affect family well-being. Although this direct final rule would not
have any impact on the autonomy or integrity of the family as an institution as defined,
this rule could impact a family’s well-being. When developing a Family Policymaking
Assessment, agencies must assess whether: (1) the action strengthens or erodes the
stability or safety of the family and, particularly, the marital commitment; (2) the action
strengthens or erodes the authority and rights of parents in the education, nurture, and
supervision of their children; (3) the action helps the family perform its functions, or
substitutes governmental activity for the function; (4) the action increases or decreases
disposable income or poverty of families and children; (5) the proposed benefits of the
action justify the financial impact on the family; (6) the action may be carried out by
State or local government or by the family; and whether (7) the action establishes an
274
implicit or explicit policy concerning the relationship between the behavior and personal
responsibility of youth, and the norms of society.
DOE has considered how the proposed benefits of this rule compare to the
possible financial impact on a family (the only factor listed that is relevant to this final
rule). As part of its rulemaking process, DOE must determine whether the energy
conservation standards contained in this direct final rule are economically justified. As
discussed in section V.C.1 of this document, DOE has determined that the standards are
economically justified because the benefits to consumers far outweigh the costs to
manufacturers. Families will also see LCC savings as a result of this final rule.
Moreover, as discussed further in section IV.I of this document, DOE’s analysis
estimated that 45 percent of low-income households who have a consumer clothes dryer
would experience a net benefit and 54 percent of low-income households who have a
consumer clothes dryer would have no impact under the adopted standards. Further, the
standards will also result in climate and health benefits for families.
I. Review Under Executive Order 12630
Pursuant to E.O. 12630, “Governmental Actions and Interference with
Constitutionally Protected Property Rights,” 53 FR 8859 (March 18, 1988), DOE has
determined that this rule would not result in any takings that might require compensation
under the Fifth Amendment to the U.S. Constitution.
275
J. Review Under the Treasury and General Government Appropriations Act, 2001
Section 515 of the Treasury and General Government Appropriations Act, 2001
(44 U.S.C. 3516, note) provides for Federal agencies to review most disseminations of
information to the public under information quality guidelines established by each agency
pursuant to general guidelines issued by OMB. OMB’s guidelines were published at 67
FR 8452 (Feb. 22, 2002), and DOE’s guidelines were published at 67 FR 62446 (Oct. 7,
2002). Pursuant to OMB Memorandum M-19-15, Improving Implementation of the
Information Quality Act (April 24, 2019), DOE published updated guidelines which are
available at
www.energy.gov/sites/prod/files/2019/12/f70/DOE%20Final%20Updated%20IQA%20G
uidelines%20Dec%202019.pdf. DOE has reviewed this direct final rule under the OMB
and DOE guidelines and has concluded that it is consistent with applicable policies in
those guidelines.
K. Review Under Executive Order 13211
E.O. 13211, “Actions Concerning Regulations That Significantly Affect Energy
Supply, Distribution, or Use,” 66 FR 28355 (May 22, 2001), requires Federal agencies to
prepare and submit to OIRA at OMB, a Statement of Energy Effects for any significant
energy action. A “significant energy action” is defined as any action by an agency that
promulgates or is expected to lead to promulgation of a final rule, and that (1) is a
significant regulatory action under Executive Order 12866, or any successor order; and
(2) is likely to have a significant adverse effect on the supply, distribution, or use of
energy, or (3) is designated by the Administrator of OIRA as a significant energy action.
For any significant energy action, the agency must give a detailed statement of any
276
adverse effects on energy supply, distribution, or use should the proposal be
implemented, and of reasonable alternatives to the action and their expected benefits on
energy supply, distribution, and use.
DOE has concluded that this regulatory action, which sets forth amended energy
conservation standards for consumer clothes dryers, is not a significant energy action
because the standards are not likely to have a significant adverse effect on the supply,
distribution, or use of energy, nor has it been designated as such by the Administrator at
OIRA. Accordingly, DOE has not prepared a Statement of Energy Effects on this direct
final rule.
L. Information Quality
On December 16, 2004, OMB, in consultation with the Office of Science and
Technology Policy (“OSTP”), issued its Final Information Quality Bulletin for Peer
Review (“the Bulletin”). 70 FR 2664 (Jan. 14, 2005). The Bulletin establishes that
certain scientific information shall be peer reviewed by qualified specialists before it is
disseminated by the Federal Government, including influential scientific information
related to agency regulatory actions. The purpose of the Bulletin is to enhance the quality
and credibility of the Government’s scientific information. Under the Bulletin, the
energy conservation standards rulemaking analyses are “influential scientific
information,” which the Bulletin defines as “scientific information the agency reasonably
can determine will have, or does have, a clear and substantial impact on important public
policies or private sector decisions.” 70 FR 2664, 2667.
277
In response to OMB’s Bulletin, DOE conducted formal peer reviews of the
energy conservation standards development process and the analyses that are typically
used and prepared a report describing that peer review.
135
Generation of this report
involved a rigorous, formal, and documented evaluation using objective criteria and
qualified and independent reviewers to make a judgment as to the
technical/scientific/business merit, the actual or anticipated results, and the productivity
and management effectiveness of programs and/or projects. Because available data,
models, and technological understanding have changed since 2007, DOE has engaged
with the National Academy of Sciences to review DOE’s analytical methodologies to
ascertain whether modifications are needed to improve DOE’s analyses. DOE is in the
process of evaluating the resulting report.
136
M. Congressional Notification
As required by 5 U.S.C. 801, DOE will report to Congress on the promulgation of
this rule prior to its effective date. The report will state that the Office of Information and
Regulatory Affairs has determined that this action meets the criteria set forth in 5 U.S.C.
804(2).
