SUPPLEMENTARY INFORMATION:
A. Statutory Authority
Part A of Title III of the Energy Policy and Conservation Act (42
U.S.C. 6291 et seq.) (EPCA) established the Energy Conservation Program
for Consumer Products Other than Automobiles. Amendments expanded Title
III of
[[Page 14369]]
EPCA to include certain commercial and industrial equipment, including
residential central air conditioners and heat pumps. (42 U.S.C.
6292(3)) In particular, the Energy Policy Act of 1992, Pub. L. 102-486
amended EPCA to direct DOE to prescribe energy conservation standards
for those residential central air conditioners and heat pumps for which
the Secretary determines that standards ``would be technologically
feasible and economically justified, and would result in significant
energy savings.'' (42 U.S.C. 6295(o)(2)(A), (o)(3))
DOE must design each standard for these products to: (1) Achieve
the maximum improvement in energy efficiency that is technologically
feasible and economically justified, and (2) result in significant
conservation of energy. (42 U.S.C. 6295(o)(2)(A)) To determine whether
a proposed standard is economically justified, DOE must, after
receiving comments on the proposed standard, determine whether the
benefits of the standard exceed its burdens to the greatest extent
practicable, considering the following seven factors:
1. The economic impact of the standard on manufacturers and
consumers of products subject to the standard;
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 which are likely to result from the imposition of the
standard;
3. The total projected amount of energy savings likely to result
directly from the imposition of the standard;
4. Any lessening of the utility or the performance of the covered
products likely to result from the imposition of 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
imposition of the standard;
6. The need for national energy conservation; and
7. Other factors the Secretary [of Energy] considers relevant.
(42 U.S.C. 6295(o)(2)(B)(i))
Prior to proposing a standard, DOE typically seeks public input on
the analytical framework, models, and tools that will be used to
evaluate standards; the results of preliminary analyses; and potential
energy conservation standard levels derived from these analyses. DOE is
publishing this document to announce the availability of the
preliminary TSD, which details the preliminary analyses, discusses the
comments on the framework document, and summarizes the preliminary
results. In addition, DOE is announcing a public meeting to solicit
feedback from interested parties on its analytical framework, models,
and preliminary results.
B. History of Standards Rulemaking for Residential Central Air
Conditioners and Heat Pumps
1. Background
Part A of Title III of the Energy Policy and Conservation Act of
1975 (EPCA), Pub. L. 94163, as amended, created the ``Energy
Conservation Program for Consumer Products Other Than Automobiles.''
(42 U.S.C. 6291-6309) This program includes residential central air
conditioners and central air-conditioning heat pumps (hereafter
referred to as central air conditioners and heat pumps). (42 U.S.C.
6292(3))
The National Appliance Energy Conservation Act of 1987 (NAECA),
Pub. L. 100-12, established energy conservation standards for central
air conditioners and heat pumps as well as requirements for determining
whether these standards should be amended. Specifically, NAECA
established energy conservation standards for central air conditioners
and heat pumps in the form of minimum limits on the seasonal energy
efficiency ratio (SEER) for air conditioners and for heat pumps
operating in the cooling mode, and on the heating seasonal performance
factor (HSPF) for heat pumps operating in the heating mode. (42 U.S.C.
6291(22)(C), 6295(d)) NAECA established the following standards for
central air conditioners and heat pumps: 10.0 SEER/6.8 HSPF for split
systems, and 9.7 SEER/6.6 HSPF for single-package systems. ``Split
systems'' consist of outdoor and indoor units which are ``split'' from
each other and connected via refrigerant tubing. The outdoor unit
resides outdoors and consists of a compressor, heat exchanger coil,
fan, and fan motor. The indoor unit, consisting of a heat exchanger
coil, resides either within a furnace or blower-coil unit, and
conditioned air is conveyed to the home via ducts. In ``single-package
systems,'' all the components that comprise a split system, including
the air circulation products, are placed in a single cabinet. The
single-package system resides outdoors, and conditioned air is conveyed
to the home via ducts. These standards became effective January 1, 1992
for split systems; standards for single-package systems came into
effect one year later. (42 U.S.C. 6295(d)(1), (d)(2)). NAECA also
required that DOE conduct two cycles of rulemakings to determine if
more stringent standards are economically justified and technologically
feasible. (42 U.S.C. 6295(d)(3))
Pursuant to 42 U.S.C. 6295(d)(3)(A), DOE published a final rule in
the Federal Register on January 22, 2001 (2001 final rule), amending
the energy conservation standards for central air conditioners and heat
pumps. 66 FR 7170. The amended standards would have increased the
minimum SEER to 13 for all central air conditioners and heat pumps,
with a corresponding HSPF of 7.7. Id.
Shortly after the publication of the 2001 final rule, DOE postponed
the effective date of the rule to reconsider the amended standards for
central air conditioners and heat pumps. DOE then promulgated a 12 SEER
and 7.4 HSPF standard in a final rule published May 23, 2002, 67 FR
36368. The U.S. Court of Appeals for the Second Circuit, however, ruled
that DOE had promulgated the 2002 final rule improperly. Natural
Resources Defense Council v. Abraham, 355 F.3d 179 (2d Cir. 2004). As a
result, DOE published a final rule on August 17, 2004, which
established a 13 SEER standard for all central air conditioners and
heat pumps, excluding through-the-wall and space-constrained systems.
69 FR 50997. This final rule constituted the first cycle of revised
standards for central air conditioners and heat pumps.
In separate court proceedings (New York versus Bodman, No. 05 Civ.
7807 (S.D.N.Y. filed Sept. 7, 2005) and Natural Resources Defense
Council versus Bodman, No. 05 Civ. 7808 (S.D.N.Y. filed Sept. 7, 2005)
the resulting consent decree (filed November 6, 2006) adopted the
schedule for central air conditioners and heat pumps that DOE published
in its January 2006 report to Congress, requiring DOE to publish a
final rule by June 30, 2011, with a compliance date of June 30, 2016.
This final rule would constitute the second cycle of revised standards
for central air conditioners and heat pumps.
More recently, EPCA was amended by the Energy Independence and
Security Act of 2007 (EISA 2007), Pub. L. 110140. In Section 306 of
EISA 2007, Congress directed DOE to: (1) Amend test procedures for all
covered products (including central air conditioners and heat pumps) to
include standby-mode and off-mode energy consumption unless current
test procedures already fully account for an incorporate standby mode
and off mode energy consumption
[[Page 14370]]
or an integrated test procedure is technically infeasible, in which
case DOE must prescribe a separate standby mode and off mode energy use
test procedure, if technically feasible (42 U.S.C. 6295(gg)(2); and (2)
incorporate standby mode and off mode energy use into any new or
amended standard published after July 1, 2010. (42 U.S.C. 6295(gg)(3))
Because this energy conservation standards rulemaking for central air
conditioners and heat pumps will be completed in 2011, the requirement
to incorporate standby-mode and off-mode energy use into the energy
conservation standards analysis applies.
2. Current Rulemaking Process
DOE prepared and published a notice announcing the availability of
the framework document, ``Energy Conservation Standards Rulemaking
Framework Document for Residential Central Air Conditioners and Heat
Pumps,'' and a public meeting to discuss the proposed analytical
framework for the rulemaking. 73 FR 32243 (June 6, 2008). DOE also
posted the framework document on its Web site describing the procedural
and analytical approaches DOE anticipated using to evaluate the
establishment of energy conservation standards for central air
conditioners and heat pumps. This document is available at: http://www1.eere.energy.gov/buildings/appliance_standards/residential/pdfs/cac_framework.pdf. DOE held a public meeting on June 12, 2008, to
describe the various rulemaking analyses DOE would conduct, such as the
engineering analysis, the life-cycle cost (LCC) and payback period
(PBP) analyses, and the national impact analysis (NIA); the methods for
conducting them; and the relationship among the various analyses.
Manufacturers, trade associations, and environmental advocates attended
the meeting. The participants discussed nine major issues: the scope of
covered product classes, definitions, test procedures, DOE's
engineering analysis, life-cycle costs, efficiency levels, regional
standards, efficiency metrics, and energy savings.
DOE developed two spreadsheets for analyzing the economic impacts
of standard levels--one that calculates LCC and PBP, and one that
calculates national impacts.\1\ DOE prepared an LCC and PBP spreadsheet
that calculates results for each of the representative units analyzed.
This spreadsheet includes product efficiency data that allows users
to determine LCC savings and PBPs based on average values, and can also
be combined with Crystal Ball (a commercially available software
program) to generate a Monte Carlo simulation, incorporating
uncertainty and variability considerations. The second economic
spreadsheet calculates the impacts of candidate standard levels on
shipments and the national energy savings (NES) and net present value
(NPV) at various standard levels. There is one national impact analysis
spreadsheet for all central air conditioners and heat pumps. DOE has
posted both economic spreadsheets on its Web site for review and
comment by interested parties.
---------------------------------------------------------------------------
\1\ For the notice of proposed rulemaking, DOE will also develop
an economic spreadsheet that will evaluate the financial impacts on
central air conditioners and heat pump manufacturers that may result
from a standard level.
---------------------------------------------------------------------------
Comments received since publication of the framework document have
helped DOE identify and resolve issues involved in the preliminary
analyses. Chapter 2 of the preliminary TSD, available at the Web link
provided in the SUMMARY section of this notice, summarizes and
addresses the comments received in response to the framework document.
C. Specific Issues for Which DOE Is Seeking Comment
DOE is specifically presenting two issues regarding the energy
conservation standards rulemaking for residential central air
conditioners and heat pumps in today's notice. There are additional
issues presented throughout the preliminary TSD for which DOE is also
seeking comment. DOE presents the analysis methodologies throughout the
preliminary TSD and summarizes the issues for which DOE seeks comment
at the end of the executive summary of the preliminary TSD.
1. Consensus Agreement
On January 26, 2010, the Air-Conditioning, Heating and
Refrigeration Institute (AHRI), American Council for an Energy
Efficient Economy (ACEEE), Alliance to Save Energy (ASE), Appliance
Standards Awareness Project (ASAP), Natural Resources Defense Council
(NRDC), and Northeast Energy Efficiency Partnerships (NEEP) submitted a
joint comment (hereafter referred to as Joint Comment 5) to DOE
recommending minimum energy conservation standards for residential
central air conditioners, heat pumps, and furnaces. (AHRI, ACEEE, ASE,
ASAP, NRDC, and NEEP, Joint Comment 5, No. 47 at pp. 1-33) The
Joint Comment 5 stated the original consensus agreement was completed
on October 13, 2009 and had 15 signatories, including AHRI, ACEEE, ASE,
NRDC, ASAP, NEEP, Northwest Power and Conservation Council (NPCC),
California Energy Commission (CEC), Bard Manufacturing Company Inc.,
Carrier Residential and Light Commercial Systems, Goodman Global Inc.,
Lennox Residential, Mitsubishi Electric & Electronics USA, National
Comfort Products, and Trane Residential.
The Joint Comment 5 recommends standards that divide the nation
into three regions for residential central air conditioners and two
regions for residential furnaces based on the population-weighted
number of heating degree days (HDD) of each State. States with 5000 HDD
or more are considered as part of the northern region, while States
with less than 5000 HDD are considered part of the southern region. For
residential central air conditioners, the Joint Comment 5 establishes a
third region--the ``southwest'' region--which is comprised of
California, Arizona, New Mexico, and Nevada. For furnaces, the
southwest region States are included in the southern region. The
compliance date specified in the agreement is May 1, 2013 for non-
weatherized furnaces and January 1, 2015 for weatherized furnaces.
In addition to the preliminary TSD, DOE is making available on its
Web site the Joint comment 5, which can be found: http://www1.eere.energy.gov/buildings/appliance_standards/residential/furnaces_boilers.html.
DOE specifically invites comment from interested parties on the
Joint Comment 5. In particular, DOE is interested in comments relating
to the proposed SEER, HSPF, and EER requirements, the proposed regional
divisions, and the proposed compliance dates for residential central
air conditioners and heat pumps.
2. Combined Rulemaking Approach
DOE is currently conducting or planning separate standards
rulemakings for three interrelated products: (1) Central air
conditioners and heat pumps; (2) gas furnaces; and (3) furnace fans.
These rulemakings are subject to the following deadlines: (1) June 30,
2011 for residential central air conditioners and heat pumps, required
by consent decree; (2) May 1, 2011 for furnaces, required as a
condition of the remand of a November 2007 final rule amending the
minimum energy conservation standards for gas furnaces; and (3) January
1, 2013 for furnace fans, required by amendments to EPCA in EISA 2007.
(42 U.S.C. 6295(f)(4)(D))
[[Page 14371]]
Rather than analyze each set of products separately, DOE is
considering combining the analyses to examine how the interaction
between the three products impacts the cost to consumers and the energy
savings resulting from potential amended standards. If DOE conducts
such an analysis and the results indicate that a combined approach
yields additional savings beyond what can be achieved by considering
each product separately, DOE may decide to pursue a combined standards
rulemaking that addresses all three products, or two of the three
products (i.e., central air conditioners and heat pumps and furnaces),
simultaneously. If such a combined rulemaking is pursued, DOE would be
required to publish the combined final rule by May 1, 2011 in order to
comply with the conditions of the remand agreement for residential
furnaces. DOE is seeking comment from interested parties relating to a
combined rulemaking regarding energy conservation standards for
residential central air conditioners and heat pumps, residential
furnaces, and furnace fans.
D. Summary of the Analyses Performed by DOE
For central air conditioners and heat pumps currently under
consideration, DOE conducted in-depth technical analyses in the
following areas: (1) Engineering, (2) energy-use characterization, (3)
markups to determine product price, (4) life-cycle cost and payback
period, and (5) national impacts. These analyses resulted in a
preliminary TSD that presents the methodology and results of each of
these analyses. The preliminary TSD is available at the Web address
given in the SUMMARY section of this notice. The analyses are described
in more detail below.
DOE also conducted several other analyses that either support the
five major analyses or are preliminary analyses that will be expanded
in the notice of proposed rulemaking (NOPR).\2\ These analyses include
the market and technology assessment, the screening analysis, which
contributes to the engineering analysis, and the shipments analysis,
which contributes to the NIA. In addition to these analyses, DOE has
begun some preliminary work on the manufacturer impact analysis and
identified the methods to be used for the LCC subgroup analysis, the
environmental assessment, the employment analysis, the regulatory
impact analysis, and the utility impact analysis. DOE will expand on
these analyses in the NOPR.
---------------------------------------------------------------------------
\2\ For past rulemakings under EPCA section 325, DOE was
required to issue an advanced notice of proposed rulemaking (ANOPR)
following publication of the framework document. EISA 2007
eliminated this requirement. Given EISA 2007's revisions to EPCA,
DOE is now using an alternative process to provide the same
information and ability for public comment as the ANOPR, but without
publication of analyses in the Federal Register.
---------------------------------------------------------------------------
Engineering Analysis
The engineering analysis establishes the relationship between the
manufacturer selling price and efficiency of a product DOE is
evaluating for energy conservation standards. This relationship serves
as the basis for cost-benefit calculations for individual consumers,
manufacturers, and the nation. The engineering analysis identifies a
representative baseline product, which is the starting point for
analyzing technologies that provide energy efficiency improvements.
Baseline product refers to a model or models having features and
technologies typically found in the minimum efficiency products
currently offered for sale. The baseline model in each product class
represents the characteristics of certain central air conditioners and
heat pumps. After identifying the baseline models, DOE estimated
manufacturer selling prices by using a consistent methodology and
pricing scheme including material and labor costs, and manufacturer's
markups. In this way, DOE developed ``manufacturer selling prices'' for
the baseline and more efficient motor designs. Later, in its Markups to
Determine Installed Price analysis, DOE converts these manufacturer
selling prices into installed prices. In the preliminary TSD, section
2.4 of chapter 2 and chapter 5 each provide detail on the engineering
analysis and the derivation of the manufacturer selling prices.
Markups To Determine Installed Price
DOE derives the installed prices for products based on manufacturer
markups, retailer markups, distributor markups, contractor markups,
builder markups, and sales taxes. In deriving these markups, DOE has
determined the distribution channels for product sales, the markup
associated with each party in the distribution channels, and the
existence and magnitude of differences between markups for baseline
products (baseline markups) and for more-efficient products
(incremental markups). DOE calculates both overall baseline and overall
incremental markups based on the product markups at each step in the
distribution channel. The overall incremental markup relates the change
in the manufacturer sales price of higher efficiency models (the
incremental cost increase) to the change in the retailer or distributor
sales price. In the preliminary TSD, section 2.5 of chapter 2 and
chapter 6 each provide detail on the estimation of markups.
Energy Use Characterization
The energy use characterization provides estimates of annual energy
consumption for central air conditioners and heat pumps, which DOE uses
in the LCC and PBP analyses and the NIA. DOE developed energy
consumption estimates for all of the product classes analyzed in the
engineering analysis, as the basis for its energy use estimates. In the
preliminary TSD, section 2.6 of chapter 2 and chapter 7 each provide
detail on the energy use characterization.
Life-Cycle Cost and Payback Period Analyses
The LCC and PBP analyses determine the economic impact of potential
standards on individual consumers. The LCC is the total consumer
expense for a product over the life of the product. The LCC analysis
compares the LCCs of products designed to meet possible energy
conservation standards with the LCCs of the products likely to be
installed in the absence of standards. DOE determines LCCs by
considering (1) total installed cost to the purchaser (which consists
of manufacturer selling price, sales taxes, distribution chain markups,
and installation cost); (2) the operating expenses of the products
(energy use and maintenance); (3) product lifetime; and (4) a discount
rate that reflects the real consumer cost of capital and puts the LCC
in present-value terms. The PBP represents the number of years needed
to recover the increase in purchase price (including installation cost)
of more efficient products through savings in the operating cost of the
product. It is the change in total installed cost due to increased
efficiency divided by the change in annual operating cost from
increased efficiency. In the preliminary TSD, section 2.7 of chapter 2
and chapter 8 each provide detail on the LCC and PBP analyses.
National Impact Analysis
The NIA estimates the NES and the NPV of total consumer costs and
savings expected to result from new standards at specific efficiency
levels (referred to as candidate standard levels). DOE calculated NES
and NPV for each level for each candidate standard for central air
conditioners and heat pumps as the difference between a base-case
forecast (without new standards) and the
[[Page 14372]]
standards case forecast (with standards). DOE determined national
annual energy consumption by multiplying the number of units in use (by
vintage) by the average unit energy consumption (also by vintage).
Cumulative energy savings are the sum of the annual NES determined over
a specified time period. The national NPV is the sum over time of the
discounted net savings each year, which consists of the difference
between total operating cost savings and increases in total installed
costs. Critical inputs to this analysis include shipments projections,
retirement rates (based on estimated product lifetimes), and estimates
of changes in shipments and retirement rates in response to changes in
product costs due to standards. In the preliminary TSD, section 2.8 of
chapter 2 and chapter 10 each provide detail on the NIA.
DOE consulted with interested parties as part of its process for
conducting all of the analyses and invites further input from the
public on these topics. The preliminary analytical results are subject
to revision following review and input from the public. A complete and
revised TSD will be made available upon issuance of a NOPR. The final
rule will contain the final analysis results and be accompanied by a
final rule TSD.
DOE encourages those who wish to participate in the public meeting
to obtain the preliminary TSD from DOE's Web site and to be prepared to
discuss its contents. A copy of the preliminary TSD is available at the
Web address given in the SUMMARY section of this notice. However,
public meeting participants need not limit their comments to the topics
identified in the preliminary TSD. DOE is also interested in receiving
views concerning other relevant issues that participants believe would
affect energy conservation standards for these products or that DOE
should address in the NOPR.
Furthermore, DOE welcomes all interested parties, regardless of
whether they participate in the public meeting, to submit in writing by
May 10, 2010, comments and information on matters addressed in the
preliminary TSD and on other matters relevant to consideration of
standards for central air conditioners and heat pumps.
The public meeting will be conducted in an informal, conference
style. A court reporter will be present to record the minutes of the
meeting. There shall be no discussion of proprietary information, costs
or prices, market shares, or other commercial matters regulated by
United States antitrust laws.
After the public meeting and the expiration of the period for
submitting written statements, DOE will consider all comments and
additional information that is obtained from interested parties or
through further analyses, and it will prepare a NOPR. The NOPR will
include proposed energy conservation standards for the products covered
by the rulemaking, and members of the public will be given an
opportunity to submit written and oral comments on the proposed
standards.
