Office of Energy Efficiency and
Renewable Energy, Department of
Energy.
ACTION: Notice of proposed rulemaking.
AGENCY:
In this notice of proposed
rulemaking (NOPR), the U.S.
Department of Energy (DOE) proposes to
reaffirm that the currently prescribed
test procedure must be used when
measuring the energy efficiency ratio,
integrated energy efficiency ratio, and
coefficient of performance for small,
large, and very large air-cooled
commercial unitary air conditioners
(CUAC) and commercial unitary heat
pumps (CUHP). With this test procedure
rulemaking, DOE fulfills its obligation
under EPCA to review its test
procedures for covered equipment at
least once every seven years and either
amend the applicable test procedures or
publish a determination in the Federal
Register not to amend them. The
proposed amendments would limit the
incorporation by reference of the
industry test procedure AHRI Standard
340/360–2007, ‘‘2007 Standard for
Performance Rating of Commercial and
Industrial Unitary Air-Conditioning and
Heat Pump Equipment’’ to certain
sections and addenda; specify
requirements for indoor airflow
tolerance and adjustment to meet other
rating conditions; clarify requirements

for condenser head pressure controls;
clarify units of measurement for airflow;
and establish a tolerance on part-load
rating points. DOE also proposes to
amend the certification, compliance,
and enforcement provisions for CUACs
and CUHPs to specify additional
reporting requirements for indoor
airflow and add enforcement provisions
for verifying the rated cooling capacity,
as the rated cooling capacity determines
which class of equipment the product
belongs to and also determines certain
testing conditions.
DATES: DOE will hold a public meeting
on this proposed test procedure if one
is requested by August 13, 2015. If a
public meeting is requested, DOE will
announce its date and location on the
DOE Web site and via email. The
meeting will also be broadcast as a
webinar. DOE will accept comments,
data, and information regarding this
notice of proposed rulemaking (NOPR)
before and after any public meeting, but
no later than September 8, 2015. See
section V, ‘‘Public Participation,’’ for
details.

VI. Approval of the Office of the Secretary
I. Authority and Background
Title III of the Energy Policy and
Conservation Act of 1975 (42 U.S.C.
6291, et seq.; ‘‘EPCA’’ or, ‘‘the Act’’) sets
forth a variety of provisions designed to
improve energy efficiency. (All
references to EPCA in this document
refer to the statute as amended through
the Energy Efficiency Improvement Act
of 2015, Pub. L. 114–11 (Apr. 30, 2015).)
Part C of Title III, which for editorial
reasons was redesignated as Part A–1
upon incorporation into the U.S. Code
(42 U.S.C. 6311–6317, as codified),
establishes the Energy Conservation
Program for Certain Commercial and
Industrial Equipment. This equipment
includes small, large, and very large aircooled commercial package air
conditioning and heating equipment—
which includes commercial unitary air
conditioners (CUACs) and commercial
unitary heat pumps (CUHPs), the
subjects of today’s notice. (42 U.S.C.
6311(1)(B)–(D))
Under EPCA, the energy conservation
program consists essentially of four
parts: (1) Testing, (2) labeling, (3)
Federal energy conservation standards,
and (4) certification and enforcement
procedures. The testing requirements
consist of test procedures that
manufacturers of covered equipment
must use as the basis for (1) certifying
to DOE that their equipment complies
with applicable energy conservation
standards adopted under EPCA, and (2)
making representations about the
efficiency of the equipment. Similarly,
DOE must use these test procedures to
determine whether the equipment
complies with any relevant standards
promulgated under EPCA.
General Test Procedure Rulemaking
Process
In 42 U.S.C. 6314, EPCA sets forth the
general criteria and procedures DOE
must follow when prescribing or
amending test procedures for covered
equipment. EPCA provides in relevant
part that any test procedures prescribed
or amended under this section must be
reasonably designed to produce test
results which measure energy
efficiency, energy use or estimated
annual operating cost of a covered
product during a representative average
use cycle or period of use and must not
be unduly burdensome to conduct. (42
U.S.C. 6314(a)(2)) In addition, if DOE
determines that a test procedure
amendment is warranted, it must
publish proposed test procedures and
PO 00000
Frm 00019
Fmt 4702
Sfmt 4702
46871
offer the public an opportunity to
present oral and written comments on
them. (42 U.S.C. 6314(b))
DOE is also required by EPCA to
conduct an evaluation of test procedures
at least every seven years for each class
of covered equipment (including CUACs
and CUHPs) to determine if an amended
test procedure would more accurately or
fully comply with the requirement to be
reasonably designed to produce test
results that reflect the energy efficiency,
energy use, and operating costs during
a representative average use cycle. DOE
must either prescribe amended test
procedures or publish a notice in the
Federal Register regarding its
determination not to amend test
procedures. (42 U.S.C. 6314(a)(1)–(2))
Background
DOE’s test procedure for CUACs and
CUHPs is codified at Title 10 of the
Code of Federal Regulations (CFR),
section 431.96. The current regulations
require that manufacturers use ANSI/
AHRI Standard 340/360–2007, ‘‘2007
Standard for Performance Rating of
Commercial and Industrial Unitary AirConditioning and Heat Pump
Equipment’’ (henceforth referred to as
ANSI/AHRI 340/360–2007) when
measuring the efficiency of a given
CUAC or CUHP and certifying that
equipment as compliant with the
applicable standard.1 77 FR 28928,
28990 (May 16, 2012).
On February 1, 2013, DOE published
a request for information and notice of
document availability regarding energy
conservation standards for CUACs and
CUHPs. 78 FR 7296. The request for
information solicited information from
the public to help DOE determine
whether national standards more
stringent than those that are currently in
place would result in a significant
amount of additional energy savings and
whether those national standards would
be technologically feasible and
economically justified. DOE also sought
information from the public on the
merits of adopting the integrated energy
efficiency ratio (IEER) as the energy
efficiency descriptor for small, large,
and very large air-cooled commercial air
conditioners and heat pumps. Currently,
manufacturers must measure the energy
efficiency of their equipment using the
energy efficiency ratio (EER), which
provides a measurement of the full-load
efficiency of a given unit. The procedure
to follow when measuring and
calculating that value, like the proposed
IEER metric, is found in ANSI/ASHRAE
1 DOE notes that for purposes of this notice, all
references to ANSI/ASHRAE 340/360–2007 include
Addenda 1 and 2 to this industry-based standard.

360–2007 at sec. 6. Comments received
on the topic of IEER are discussed in a
related energy conservation standards
NOPR, which was published in
September 2014. 79 FR 58948 (Sept. 30,
2014).
Subsequently, on April 1, 2015, DOE
issued a notice of intent to establish the
Commercial Package Air Conditioners
and Heat Pumps and Commercial Warm
Air Furnaces Working Group to
negotiate either a notice of proposed
rulemaking (NOPR) or final rule for
energy conservation standards for this
equipment. 80 FR 17363. This Working
Group was established under the
Appliance Standards and Rulemaking
Federal Advisory Committee (ASRAC)
in accordance with the Federal
Advisory Committee Act and the
Negotiated Rulemaking Act. See 5
U.S.C. Appendix—Federal Advisory
Committee Act and 5 U.S.C. 561–570a.
The Working Group, which consisted of
17 members, including one member
from ASRAC and one DOE
representative, met six times (five times
in-person and once by teleconference).
The meetings were held on April 28,
May 11–12, May 20–21, June 1–2, June
9–10, and June 15, 2015. The Working
Group successfully reached consensus
on energy conservation standards for
commercial package air conditioners
and heat pumps and commercial warm
air furnaces, which included the
Working Group’s recommendations to
ASRAC on the energy conservation
standards. The group also chose to
provide test procedure and metricrelated recommendations to the
committee. ASRAC voted unanimously
to approve the Working Group’s
recommendations on June 17, 2015.
Consistent with those
recommendations, DOE proposes to
amend the test procedure and associated
certification regulations for small, large,
and very large air-cooled commercial
package air conditioning and heating
equipment to implement the Working
Group’s recommendations. Participants

DOE considers the activity associated
with this rulemaking sufficient to satisfy
the statutory requirement that DOE
review its test procedures for all covered
equipment, including CUACs and
CUHPs, at least once every seven years
and either amend the applicable test
procedures or publish a determination
in the Federal Register not to amend
them. (42 U.S.C. 6314(a)(1))

II. Summary of the Notice of Proposed
Rulemaking
DOE is proposing several
amendments to its regulations related to
the test procedures prescribed for
CUACs and CUHPs in 10 CFR part 431,
subpart F. First, DOE proposes to amend
the current DOE test procedure to
incorporate only certain sections of
ANSI/AHRI 340/360–2007 rather than
in its entirety. Second, DOE proposes
amendments to incorporate a tolerance
on the indoor airflow rate. In particular,
during full load testing in cooling mode,
the indoor airflow rate would be
required to remain within +/¥5 percent
of the rated full-load indoor airflow. The
unit and/or test facility must be adjusted
VerDate Sep<11>2014
16:37 Aug 05, 2015
Jkt 235001
to maintain this tolerance for indoor
airflow rate while ensuring that the ESP
remains within the tolerance required
by the test procedure. For any other
condition using full-load airflow (e.g.
full-load heating for a heat pump), the
+/¥5 percent tolerance would also
apply and, if necessary, a test facility
adjustment would be made in order to
maintain air flow within the required
tolerance, but the unit itself may not be
adjusted. Third, DOE proposes to clarify
that condenser head pressure controls, if
included with the unit, must be active
during testing. Fourth, DOE proposes to
clarify that reference to cubic feet per
minute (CFM) in ANSI/AHRI 340/360–
2007 must be interpreted as referring to
standard CFM (SCFM). Fifth, DOE
proposes that when conducting partload testing to measure IEER, the
difference between the percent load
calculated for a part-load test point and
its target value may be as much as three
percent without requiring interpolation
or application of the cyclic degradation
factor specified in ANSI/AHRI 340/360–
2007. Sixth, DOE proposes to amend the
certification, compliance, and
PO 00000
Frm 00020

Sfmt 4702
Affiliation
enforcement provisions for CUACs and
CUHPs. These amendments include
adding enforcement provisions for
verifying the cooling capacity, as the
cooling capacity determines which class
of equipment the product belongs to and
also determines certain testing
conditions. Lastly, DOE has proposed a
definition of integrated energy
efficiency ratio (IEER).
DOE believes that none of these
clarifications or amendments would
result in any changes to the energy
efficiency of current equipment.
Representations of energy efficiency
metrics would be required to be based
on the amended test procedure
beginning 360 days after the date of
publication of the final rule. 42 U.S.C.
6314(d) (prescribing a 360-day period
after a test procedure’s publication by
which manufacturer representations of
energy consumption or energy costs
must be based on that procedure).

III. Discussion
A. Amendments to the Current DOE
Test Procedure
DOE proposes making several
amendments to the current DOE test
procedure, which incorporates ANSI/
AHRI 340/360–2007 by reference. These
amendments are detailed below.
mstockstill on DSK4VPTVN1PROD with PROPOSALS
1. Sections of ANSI/AHRI 340/360–2007
Incorporated by Reference
Currently, 10 CFR 431.96, Table 2,
specifies that when measuring the
energy efficiency of CUACs and CUHPs
using the metrics EER and coefficient of
performance (COP), ANSI/AHRI 340/
360–2007 must be used, but omitting
section 6.3 of that industry testing
standard. DOE proposes that when
testing CUACs and CUHPs using the
EER, COP, and IEER metrics, only
certain sections of ANSI/AHRI 340/360–
2007 are required, specifically sections
3, 4, and 6 (but, again, omitting section
6.3), rather than applying the entirety of
ANSI/AHRI 340/360–2007. The sections
DOE proposes to incorporate are those
that include the relevant testing
provisions that apply directly to the
DOE test procedure, while the excluded
sections contain provisions unrelated to
the DOE test procedure. DOE proposes
not to incorporate section 5 of ANSI/
AHRI 340/360–2007, which consists of
a single sentence referring to use of
ASHRAE 37, ‘‘Methods of Testing for
Rating Unitary Air-Conditioning and
Heat Pump Equipment,’’ for test
methods and procedures. DOE proposes
this change because the version of this
test method is not specified. Instead,
DOE proposes to incorporate by
reference the most recent version of this
test procedure—ANSI/ASHRAE 37–
2009. The test standard would be listed
in 10 CFR 431.95, and incorporated by
reference in 10 CFR 431.96. In case of
a conflict between ANSI/AHRI 340/360–
2007 or ANSI/ASHRAE 37–2009 and
the CFR, the CFR provisions control.
2. Indoor Airflow Adjustment and
Reporting
Section 6.1.3.2 of ANSI/AHRI 340/
360–2007 establishes minimum external
static pressure (ESP) rating requirements
for different equipment capacities and
requirements for the indoor-coil airflow
rate for determining standard ratings.
DOE notes that AHRI 340/360 also refers
to ESP as ‘‘external pressure’’ and
‘‘external resistance.’’ Section 6.1.3.2
establishes a tolerance of ¥0 in. H2O to
+0.05 in. H2O for ESP (i.e., the measured
ESP may not be any lower but can be
up to 0.05 in. H2O higher than the
required minimum) but does not
contain a tolerance for the airflow rate.
VerDate Sep<11>2014
16:37 Aug 05, 2015
Jkt 235001
Manufacturers are currently required to
report, among other information, the
model number and specifications of the
motor and the drive kit, including
settings, associated with that specific
motor that were used to determine the
certified rating; as well as the rated
airflow in SCFM for each fan coil; in the
supplemental information submitted
with the certification report for the unit.
(See 10 CFR 429.43(b)(4)(i))
DOE proposes that any subsequent
testing (e.g., DOE assessment and
enforcement testing) must use the same
motor and drive assembly and settings
specified in the certification
information, and that the party
conducting testing would be required to
ensure that the ESP is within the
tolerances set forth in Section 6.1.3.2 of
ANSI/AHRI 340/360–2007 and must
verify that the indoor airflow rate is
within +/¥5 percent of the
manufacturer-rated full-load indoor
airflow rate. If the indoor airflow in
SCFM measured at the required ESP is
outside the +/¥5 percent tolerance, the
unit and/or test facility must be adjusted
to set up the unit such that both the
airflow and ESP are within the required
tolerances. This process may include,
but is not limited to, adjusting any
adjustable motor sheaves, adjusting
variable frequency drive (VFD) settings,
or adjusting the code tester fan. DOE
believes that the proposed 5 percent
tolerance on airflow is an appropriate
compromise of test burden and
precision because holding this tolerance
has been possible without difficulty in
DOE’s own testing, and because testing
and analysis shows that the impact of
up to 5 percent airflow rate variation on
capacity and IEER is minimal. For
example, DOE testing of a 7.5-ton CUAC
unit suggested that 5 percent variation
in the full-load airflow would cause 0.5
percent variation in EER and 0.8 percent
variation in capacity. DOE also used
data available in manufacturer data
sheets to calculate IEER as a function of
indoor airflow for several commercial
air conditioners and determined that a
5 percent variation in airflow would be
expected to cause, on average, a 1.5
percent variation in IEER. (See EERE–
2015–BT–TP–0015.) DOE requests
comment on the appropriateness of the
+/¥5 percent tolerance and/or data that
might show that a different tolerance
level might be more appropriate. This is
Issue 1 in section V.B, ‘‘Issues on Which
DOE Seeks Comment.’’
ANSI/AHRI 340/360–2007, section
6.1.3.2.e specifies that the full-load
cooling airflow rate must be employed
for any other condition using full-load
air flow (e.g., full-load heating) without
regard to resulting ESP. DOE proposes
PO 00000
Frm 00021
Fmt 4702
Sfmt 4702
46873
that the +/¥5 percent tolerance for air
flow rate must be applied for these other
conditions as well. If necessary, a test
facility adjustment may have to be made
in order to maintain air flow within the
required tolerance; for example,
adjustment of the code tester fan may be
needed to ensure air flow within the
specified tolerance range even if the ESP
is no longer within the range specified
for operation in full-capacity cooling
mode. (In this situation, the tester
would not adjust the unit under test.)
DOE requests comments on this
interpretation and clarification of the
requirements of ANSI/AHRI 340/360–
2007, section 6.1.3.2.e, regarding
operation in modes other than fullcapacity cooling. This is Issue 2 in
section V.B, ‘‘Issues on Which DOE
Seeks Comment.’’
DOE realizes that some units may be
designed to operate with a different
indoor airflow rate for cooling or
heating mode, such as when the unit
incorporates variable speed indoor fans.
In that case, DOE proposes that
manufacturers would report the
individual indoor airflow rates in
cooling and heating mode. DOE is
proposing this approach in order to
capture air flow rates used in the
different full-load tests (i.e., heating and
cooling). DOE requests comment on
whether marketed units actually operate
in this manner, and if so, whether this
proposed provision would be
appropriate for such units. This is Issue
3 in section V.B, ‘‘Issues on Which DOE
Seeks Comment.’’
DOE also proposes that a
manufacturer must include in its
certification report the adjusted indoor
airflow at each part-load condition.
Inclusion of these part-load air flow
rates would allow confirmation that,
during any subsequent third-party
testing, the equipment is operating at
part-load as rated.
3. Condenser Head Pressure Controls
Note 2 of Table 6 of ANSI/AHRI 340/
360–2007 specifies that condenser
airflow should be adjusted as required
by the unit controls for head pressure
control. Condenser head pressure
controls regulate the flow of refrigerant
through the condenser and/or adjust
operation of condenser fans to prevent
condenser pressures from dropping too
low during low-ambient operation.
When employed, these controls ensure
that the refrigerant pressure is high
enough to maintain adequate flow
through refrigerant expansion devices
such as thermostatic expansion valves.
The use of condenser head pressure
controls influences a unit’s
performance, making it important that
E:\FR\FM\06AUP1.SGM

46874
Federal Register / Vol. 80, No. 151 / Thursday, August 6, 2015 / Proposed Rules
this feature be operating during the test
because it would be operating in the
field. DOE proposes to specify that
condenser head pressure controls, if
included with the unit, must be active
during testing.
The use of condenser head pressure
controls may prevent a unit from
reaching steady state prior to testing.
For example, a unit employing
condenser head pressure control might
cycle a condenser fan to control head
pressure. The current DOE test
procedure does not address such
operation. Hence, if a unit with
condenser head pressure controls
cannot achieve steady-state operation
with the controls active, and thus
cannot be tested, the manufacturer
would have to request a waiver. See 10
CFR 431.401 (‘‘Any interested person
may submit a petition to waive for a
particular basic model the requirements
of any uniform test method contained in
this part, upon the grounds that . . . the
basic model contains one or more
design characteristics that prevent
testing of the basic model according to
the prescribed test procedures.’’) DOE
requests comment on whether there are
any units sold for which this might
occur and what changes, if any, may be
needed to DOE’s proposal to address
this scenario. This is Issue 4 in section
V.B, ‘‘Issues on Which DOE Seeks
Comment.’’

4. Unit of Measurement for Airflow
ANSI/AHRI 340/360–2007 lacks
clarity regarding references to CFM as
opposed to SCFM. In order to resolve
this, DOE proposes that all instances of
CFM as a unit of airflow must be
interpreted to mean SCFM where they
appear in the sections of ANSI/AHRI
340/360–2007 incorporated by reference
in 10 CFR part 431, subpart F.
calculated percent load for one of the
part-load tests is 75.5 percent, are the
results of this test acceptable for use as
the 75 percent part-load test point
condition?
DOE proposes to apply a
+/¥3 percent tolerance to each part
load test point. In other words, the
difference between the percent load
calculated for a part-load test point and
its target value may be as much as 3
percent and still be considered to be
operating at the target part-load test
point. DOE anticipates that this
proposal will reduce testing time and
burden by eliminating additional partload tests in cases where operation
closely approaches but does not exactly
meet the target part-load test points.
DOE requests comment on establishing
this tolerance and on the
appropriateness of the proposed
tolerance level. This is Issue 5 in section
V.B, ‘‘Issues on Which DOE Seeks
Comment.’’
B. Certification and Enforcement Issues
1. Measuring Cooling Capacity for
Purposes of Certification, Assessment,
and Enforcement
Manufacturers must certify and report
CUAC and CUHP cooling capacity (in
Btu/h) when certifying the efficiency of
this equipment, per 10 CFR 429.43(b)(2).
The cooling capacity represented by
manufacturers for certification and
compliance purposes must be
determined through testing in
accordance with 10 CFR 431.96. DOE
proposes that the cooling capacity
certified to DOE for a given basic model
must be the average of the capacities
measured for the sample of units tested
to certify that basic model, rounded
according to the multiples in Table 4 in
ANSI/AHRI 340/360–2007.
DOE proposes that when conducting
assessment and enforcement testing, the
total cooling capacity must be measured
pursuant to the test requirements of 10
CFR 431.96 for each unit tested, and the
results of the measurement(s) (either the
measured cooling capacity for a single
unit sample or the average of the
measured cooling capacities for a
multiple-unit sample) compared to the
value of cooling capacity certified by the
manufacturer. The manufacturercertified cooling capacity will be
considered valid if the cooling capacity
determined through DOE testing is
within five percent of the certified
cooling capacity.
5. Tolerance on Percent Load for IEER
Part-Load Tests
For calculating IEER, section 6.2.2 of
ANSI/AHRI 340/360–2007 specifies that
the unit efficiency must be determined
at 100 percent, 75 percent, 50 percent,
and 25 percent load (defined as partload net cooling capacity divided by
full-load net cooling capacity, then
multiplied by 100 percent) at the
conditions specified in Table 6 of ANSI/
AHRI 340/360–2007 (Table 6). ANSI/
AHRI 340/360–2007 also provides
instruction for when a unit cannot
operate at the 75 percent, 50 percent,
and 25 percent part-load test points, but
does not specify a tolerance for the
percent load, i.e. how much can the load 2. Compliance Dates of the Test
deviate from the part-load test point and Procedure Amendments

package air conditioning and heating
equipment, EPCA directs DOE to
determine to what extent, if any, the test
procedure would alter the measured
energy efficiency or measured energy
use of a covered product. (42 U.S.C.
6314(a)(4)) If the amended test
procedure alters the measured energy
efficiency or measured energy use, the
Secretary must amend the applicable
energy conservation standard
accordingly. (42 U.S.C. 6314(a)(4)
(requiring that the provisions of 42
U.S.C. 6293(e), which includes
determining the impact that changes to
a test procedure would have on the
measured energy efficiency or energy
use of a covered product))
In DOE’s view, no aspect of this
NOPR is likely to alter the measured
efficiency of CUACs and CUHPs. These
proposed amendments, which follow
the Working Group’s recommendations,
relate to DOE’s efforts to establish
amended energy conservation standards
for CUACs and CUHPs. As part of that
standards rulemaking effort, DOE had
proposed, and the Working Group
adopted, an approach that would base
the amended standards for this
equipment on IEER instead of EER. See
79 FR 58947 at 58956 (September 30,
2014); ASRAC Commercial Package Air
Conditioners and Commercial Warm Air
Furnaces Working Group Term Sheet, at
2 (June 15, 2015). DOE has also
proposed a definition of IEER to support
the Working Group’s approach.
Consistent with this transition to IEER
as the reporting metric for this
equipment, DOE proposes to require the
reporting of indoor part-load airflow
rates used in the IEER calculation as of
the compliance date of the new
standard. DOE also proposes another
amendment associated with the
measurement of IEER—applying a +/¥
3 percent tolerance to each part-load test
point for IEER ratings. This proposed
amendment, if adopted, would be
required as of the compliance date of
the new standard.
The proposed amendments not
specifically related to IEER would,
rather than alter the measured efficiency
or measured energy use of CUAC and
CUHP equipment, clarify how to test
this equipment. These proposed
amendments would limit the
incorporation by reference of ANSI/
AHRI 340/360–2007 to certain sections,
establish a tolerance on full-load indoor
airflow, add condenser head pressure
control requirements, and clarify units
of measurement for airflow. These
proposals, if adopted, would result in
no procedural changes related to how
testing would be performed. These
proposed amendments, if adopted,
E:\FR\FM\06AUP1.SGM
06AUP1
Federal Register / Vol. 80, No. 151 / Thursday, August 6, 2015 / Proposed Rules
would become effective 30 days after
publication of the final rule in the
Federal Register. Consistent with 42
U.S.C. 6314(d), any representations of
energy consumption of CUACs and
CUHPs must be based on any final
amended test procedures 360 days after
the publication of the test procedure
final rule.
IV. Procedural Issues and Regulatory
Review
A. Review Under Executive Order 12866
The Office of Management and Budget
(OMB) has determined that test
procedure rulemakings do not constitute
‘‘significant regulatory actions’’ under
section 3(f) of Executive Order 12866,
Regulatory Planning and Review, 58 FR
51735 (Oct. 4, 1993). Accordingly, this
action was not subject to review under
the Executive Order by the Office of
Information and Regulatory Affairs
(OIRA) in the Office of Management and
Budget.
mstockstill on DSK4VPTVN1PROD with PROPOSALS
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) 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 Executive Order 13272,
‘‘Proper Consideration of Small Entities
in Agency Rulemaking,’’ 67 FR 53461
(August 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 DOE
rulemaking process. 68 FR 7990. DOE
has made its procedures and policies
available on the Office of the General
Counsel’s Web site: https://energy.gov/
gc/office-general-counsel.
DOE reviewed today’s proposed rule
under the provisions of the Regulatory
Flexibility Act and the procedures and
policies published on February 19,
2003. This proposed rule prescribes test
procedures that will be used to test
compliance with energy conservation
standards for the equipment that are the
subject of this rulemaking. DOE has
tentatively concluded that the proposed
rule would not have a significant impact
on a substantial number of small
entities.
For manufacturers of small, large, and
very large air-cooled CUAC and CUHP,
the Small Business Administration
(SBA) has set a size threshold, which
defines those entities classified as
VerDate Sep<11>2014
16:37 Aug 05, 2015
Jkt 235001
‘‘small businesses’’ for the purposes of
the statute. DOE used the SBA’s small
business size standards to determine
whether any small entities would be
subject to the requirements of the rule.
65 FR 30836, 30848 (May 15, 2000), as
amended at 65 FR 53533, 53544 (Sept.
5, 2000) and codified at 13 CFR part
121. The size standards are listed by
North American Industry Classification
System (NAICS) code and industry
description and are available at https://
www.sba.gov/category/navigationstructure/contracting/contractingofficials/small-business-size-standards.
Manufacturing of small, large, and very
large air-cooled CUAC and CUHP is
classified under NAICS 333415, ‘‘AirConditioning and Warm Air Heating
Equipment and Commercial and
Industrial Refrigeration Equipment
Manufacturing.’’ The SBA sets a
threshold of 750 employees or less for
an entity to be considered as a small
business for this category. DOE initially
identified 12 potential manufacturers of
commercial packaged air conditioners
sold in the U.S. DOE then determined
that 10 were large manufacturers,
manufacturers that are foreign-owned
and -operated, or manufacturers that do
not produce products covered by this
rulemaking. DOE was able to determine
that 2 manufacturers meet the SBA’s
definition of a ‘‘small business’’ and
manufacture products covered by this
rulemaking.
DOE expects the impact of the
proposed rule on manufacturers,
including small businesses, to be
minimal. The proposed rule would
amend DOE’s certification requirements
to specify additional reporting
requirements and add enforcement
provisions for verifying cooling
capacity. The proposed rule would also
clarify or amend DOE’s test procedures
to amend AHRI Standard 340/360–2007,
‘‘2007 Standard for Performance Rating
of Commercial and Industrial Unitary
Air-Conditioning and Heat Pump
Equipment,’’ to incorporate certain
sections by reference, specify
requirements for airflow adjustment and
tolerance to meet other rating
conditions, require units with
condenser head pressure controls to be
tested with those controls active, clarify
the unit of measurement for airflow, and
establish a tolerance on part-load rating
points.
The Working Group has
recommended amended energy
conservation standards rulemaking that
the standards will be based on the
metric of integrated energy efficiency
ratio (IEER) instead of energy efficiency
ratio (EER). DOE expects the impact on
test burden to be modest. AHRI ratings
PO 00000
Frm 00023
Fmt 4702
Sfmt 4702
46875
already include IEER, indicating that
many manufacturers, representing a
large portion of the market, already
determine IEER for their units. ANSI/
ASHRAE/IES Standard 90.1–2013—
Energy Standard for Buildings Except
Low-Rise Residential Buildings
(ASHRAE 90.1–2013) has adopted an
IEER requirement, which makes
reporting of IEER necessary for
shipment to those states and localities
that will adopt that standard in building
codes. Current procedures relating to
alternative efficiency determination
methods (AEDMs), including
procedures for certifying IEER, require a
limited amount of testing to be
conducted when validating an AEDM
for CUACs and CUHPs. 10 CFR
429.70(c)(2)(iv) (detailing the minimum
number of distinct basic models
required to be test for purposes of
AEDM validation for different
equipment types and classes) . DOE
expects that most CUAC and CUHP
ratings will be based on results obtained
from AEDMs. Although DOE recognizes
that some ratings will be based on
testing, DOE expects these ratings to
comprise a small minority of products.
However, to help DOE better
understand the burdens when
measuring IEER instead of EER, DOE
requests comment and data on
manufacturer expectations of the
number of models that will likely be
tested rather than rated with an AEDM.
DOE encourages confidential data
submissions if necessary in order to
ensure that such data can be provided.
For these reasons, DOE certifies that
this proposed rule would not have a
significant economic impact on a
substantial number of small entities.
Accordingly, DOE has not prepared a
regulatory flexibility analysis for this
rulemaking. DOE will transmit the
certification and supporting statement
of factual basis to the Chief Counsel for
Advocacy of the SBA for review under
5 U.S.C. 605(b).
C. Review Under the Paperwork
Reduction Act of 1995
Manufacturers of small, large, and
very large air-cooled CUAC and CUHP
equipment must certify to DOE that
their equipment complies with any
applicable energy conservation
standards. In certifying compliance,
manufacturers must test their
equipment according to the appropriate
DOE test procedures for this equipment,
including any applicable amendments.
DOE has established regulations for the
certification and recordkeeping
requirements for all covered consumer
products and commercial equipment,
including CUACs and CUHPs. See 10
E:\FR\FM\06AUP1.SGM

Federal Register / Vol. 80, No. 151 / Thursday, August 6, 2015 / Proposed Rules
mstockstill on DSK4VPTVN1PROD with PROPOSALS
CFR part 429, subpart B. The collectionof-information requirement for the
certification and recordkeeping is
subject to review and approval by OMB
under the Paperwork Reduction Act
(PRA).
In the Certification of Commercial
Equipment Final Rule published in May
2014, DOE amended existing regulations
governing compliance certification for a
variety of commercial equipment
covered by EPCA, which affected CUAC
and CUHP manufacturers. 79 FR 25486
at 25502 (May 5, 2014). In today’s
NOPR, DOE proposes to amend its
certification requirements to specify
additional reporting requirements. DOE
does not believe that these additions to
the certification requirements constitute
a significant additional burden upon
respondents, as they require minimal
additional information to what
manufacturers must already report in
their certification reports. DOE believes
that the Certification of Commercial
Equipment Final Rule provides an
accurate estimate of the existing burden
on respondents and would continue to
apply to the relevant aspects of the
proposed amendments. See 79 FR at
25496–25498 (detailing burden
estimates and indicating an average
burden of approximately 30 hours per
company on an annual basis). OMB has
approved the revised information
collection for DOE’s certification and
recordkeeping requirements. 80 FR 5099
(January 30, 2015).
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
In this proposed rule, DOE proposes
test procedure amendments that it
expects will be used to develop and
implement future energy conservation
standards for commercial unitary air
conditioners and commercial unitary
heat pumps. DOE has determined that
this rule falls into a class of actions that
are categorically excluded from review
under the National Environmental
Policy Act of 1969 (42 U.S.C. 4321 et
seq.) and DOE’s implementing
regulations at 10 CFR part 1021.
Specifically, this proposed rule would
amend the existing test procedures
without affecting the amount, quality or
distribution of energy usage, and,
therefore, would not result in any
environmental impacts. Thus, this
rulemaking is covered by Categorical
VerDate Sep<11>2014
16:37 Aug 05, 2015
Jkt 235001
Exclusion A5 under 10 CFR part 1021,
subpart D, which applies to any
rulemaking that interprets or amends an
existing rule without changing the
environmental effect of that rule.
Accordingly, neither an environmental
assessment nor an environmental
impact statement is required.
E. Review Under Executive Order 13132
Executive Order 13132, ‘‘Federalism,’’
64 FR 43255 (August 4, 1999) imposes
certain requirements on 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
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 proposed 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 equipment that is the subject of
today’s proposed 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(d)) No further action is required by
Executive Order 13132.
F. Review Under Executive Order 12988
Regarding the review of existing
regulations and the promulgation of
new regulations, section 3(a) of
Executive Order 12988, ‘‘Civil Justice
Reform,’’ 61 FR 4729 (Feb. 7, 1996),
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. Section 3(b) of
Executive Order 12988 specifically
requires that Executive agencies make
every reasonable effort to ensure that the
PO 00000
Frm 00024

regulation: (1) Clearly specifies 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 Executive Order
12988 requires Executive agencies to
review regulations in light of applicable
standards in sections 3(a) and 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, the proposed
rule meets the relevant standards of
Executive Order 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
proposed 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 proposed ‘‘significant
intergovernmental mandate,’’ and
requires an agency plan for giving notice
and opportunity for timely input to
potentially affected small governments
before establishing any requirements
that might significantly or uniquely
affect small governments. On March 18,
1997, DOE published a statement of
policy on its process for
intergovernmental consultation under
UMRA. 62 FR 12820; also available at
https://energy.gov/gc/office-generalcounsel. DOE examined this proposed
rule according to UMRA and its
statement of policy and determined that
the proposed rule contains neither an
intergovernmental mandate, nor a
mandate that may result in the
expenditure of $100 million or more in
E:\FR\FM\06AUP1.SGM

any year, so these requirements do not
apply.
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. This
rule would not have any impact on the
autonomy or integrity of the family as
an institution. Accordingly, DOE has
concluded that it is not necessary to
prepare a Family Policymaking
Assessment.
I. Review Under Executive Order 12630
DOE has determined, under Executive
Order 12630, ‘‘Governmental Actions
and Interference with Constitutionally
Protected Property Rights’’ 53 FR 8859
(March 18, 1988), that this regulation
would not result in any takings that
might require compensation under the
Fifth Amendment to the U.S.
Constitution.

J. Review Under 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 agencies to review most
disseminations of information to the
public under 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). DOE has reviewed
today’s proposed 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
Executive Order 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 OMB, a
Statement of Energy Effects for any
proposed significant energy action. A
‘‘significant energy action’’ is defined as
any action by an agency that
promulgated 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
VerDate Sep<11>2014
16:37 Aug 05, 2015
Jkt 235001
any proposed significant energy action,
the agency must give a detailed
statement of any 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.
Today’s regulatory action to amend
the test procedure for measuring the
energy efficiency of CUACs and CUHPs
is not a significant regulatory action
under Executive Order 12866.
Moreover, it would not have a
significant adverse effect on the supply,
distribution, or use of energy, nor has it
been designated as a significant energy
action by the Administrator of OIRA.
Therefore, it is not a significant energy
action, and, accordingly, DOE has not
prepared a Statement of Energy Effects.
L. Review Under Section 32 of the
Federal Energy Administration Act of
1974
Under section 301 of the Department
of Energy Organization Act (Pub. L. 95–
91; 42 U.S.C. 7101), DOE must comply
with section 32 of the Federal Energy
Administration Act of 1974, as amended
by the Federal Energy Administration
Authorization Act of 1977. (15 U.S.C.
788; FEAA) Section 32 essentially
provides in relevant part that, where a
proposed rule authorizes or requires use
of commercial standards, the notice of
proposed rulemaking must inform the
public of the use and background of
such standards. In addition, section
32(c) requires DOE to consult with the
Attorney General and the Chairman of
the Federal Trade Commission (FTC)
concerning the impact of the
commercial or industry standards on
competition.
The proposed rule incorporates
testing methods contained in the
following commercial standards: ANSI/
AHRI Standard 340/360–2007 and
ANSI/ASHRAE Standard 37–2009. The
Department has evaluated these
standards and is unable to conclude
whether they fully comply with the
requirements of section 32(b) of the
FEAA, (i.e., that they were developed in
a manner that fully provides for public
participation, comment, and review).
DOE will consult with the Attorney
General and the Chairman of the FTC
concerning the impact of these test
procedures on competition, prior to
prescribing a final rule.
M. Description of Materials
Incorporated by Reference
DOE is proposing to incorporate by

B. Issues on Which DOE Seeks Comment
Although DOE welcomes comments
on any aspect of this proposal, DOE is
particularly interested in receiving
comments and views of interested
parties concerning the following issues:
1. DOE proposes that when
conducting full-load cooling tests with
the appropriate external static pressure
(ESP) condition in Table 5 of ANSI/
AHRI 340/360–2007, the tester must use
the motor and drive kit that was used to
determine the certified rating, as
specified in the manufacturer’s
certification information. During such
testing, the indoor airflow must be
within +/¥5 percent of the
manufacturer’s rated full-load indoor
airflow rate. If the indoor airflow at the
required ESP is outside the +/¥5
percent tolerance, make necessary
adjustments to the test setup and/or the
unit such that both the airflow and ESP
are within the required tolerances. DOE
requests comment on the
appropriateness of the +/¥5 percent
tolerance and/or data showing that a
different tolerance level might be more
appropriate, as well as feedback on the
burden of maintaining airflow within
the tolerance. See section III.A.2 for
details.
PO 00000
Frm 00026
Fmt 4702
Sfmt 4702
2. Section 6.1.3.2.e of ANSI/AHRI
340/360–2007 specifies that the fullload cooling airflow rate must be
maintained for any other condition
using full-load air flow (e.g., full-load
heating) without regard to resulting ESP.
DOE proposes that in this situation, the
+/¥5 percent tolerance on the full-load
cooling airflow rate must also apply. To
maintain the airflow within the required
tolerance, the tester may make
adjustments to the test facility or
apparatus, but not the unit being tested.
DOE requests comments on this
interpretation and clarification of the
requirements of section 6.1.3.2.e of
ANSI/AHRI 340/360–2007 regarding
operation in modes other than fullcapacity cooling. See section III.A.2 for
details.
3. For all units, certification
requirements already include reporting
of the indoor airflow at full capacity
cooling operation. If units are designed
to operate with a different indoor
airflow for cooling and heating mode,
DOE proposes that manufacturers would
separately report the indoor airflow in
cooling and heating mode. DOE requests
comment on whether this approach is
appropriate and also requests comment
on whether any units in the market are
designed to operate with a different fullload air flow for heating and cooling
modes. See section III.A.2 for details.
4. DOE proposes that condenser head
pressure controls, if included in a unit,
must be active during testing. DOE
requests comment on whether there are
any units on the market with condenser
head pressure controls that would
prevent the unit from achieving steady
state under the test conditions. If so,
how should DOE address these kinds of
units for testing purposes? See section
III.A.3 for details.
5. For calculating IEER, section 6 of
ANSI/AHRI 340/360–2007 specifies that
the unit efficiency must be determined
at 100 percent, 75 percent, 50 percent,
and 25 percent load (defined as net partload cooling capacity divided by fullload net cooling capacity times 100
percent). ANSI/AHRI 340/360–2007 also
provides instruction for when a unit
cannot operate at the 75 percent, 50
percent, and 25 percent part-load test
points, but does not specify a tolerance
for the percent load, i.e. how much can
the load deviate from the part-load test
point and still be considered operating
at the part-load test point. DOE proposes
to apply a +/¥3 percent tolerance on
the percent load for approach to each
part-load rating point. In other words,
the difference between the percent load
calculated for a part-load test point and
its target value may be as much as 3
percent and still be considered to be
E:\FR\FM\06AUP1.SGM
06AUP1
Federal Register / Vol. 80, No. 151 / Thursday, August 6, 2015 / Proposed Rules
operating at the target part-load test
point. DOE requests comment on the
appropriateness of the tolerance level.

CUHPs), including compliance certifications,
must be based on testing conducted in
accordance with Table 1 to § 431.96.
(1) Cooling mode test method. The test
method for testing commercial unitary air
conditioners and commercial unitary heat
pumps in cooling mode must consist of
application of the methods and conditions in
ANSI/AHRI 340/360–2007 sections 3, 4, and
6 (omitting section 6.3) (incorporated by
reference; see § 431.95), and in ANSI/
ASHRAE 37–2009 (incorporated by
reference; see § 431.95). In case of a conflict
between ANSI/AHRI 340/360–2007 or ANSI/
ASHRAE 37–2009 and the CFR, the CFR
provisions control.
(2) Heating mode test method. The test
method for testing commercial unitary heat
pumps in heating mode must consist of
application of the methods and conditions in
ANSI/AHRI 340/360–2007 sections 3, 4, and
6 (omitting section 6.3) (incorporated by
reference; see § 431.95), and in ANSI/
ASHRAE 37–2009 (incorporated by
reference; see § 431.95). In case of a conflict
between ANSI/AHRI 340/360–2007 or ANSI/
ASHRAE 37–2009 and the CFR, the CFR
provisions control.
(3) Minimum External Static Pressure. Use
the certified cooling capacity for the basic
model to choose the minimum external static
pressure found in table 5 of section 6 of
ANSI/AHRI 340/360–2007 for testing.
(4) Optional Break-in Period.
Manufacturers may optionally specify a
‘‘break-in’’ period, not to exceed 20 hours, to
operate the equipment under test prior to
conducting the test method in appendix A.
A manufacturer who elects to use an optional
compressor break-in period in its
certification testing should record this
information (including the duration) as part
of the information in the supplemental
testing instructions under 10 CFR 429.43.
(5) Additional Provisions for Equipment
Set-up. The only additional specifications
that may be used in setting up a unit for test
are those set forth in the installation and
operation manual shipped with the unit.
Each unit should be set up for test in
PO 00000
Frm 00029
Fmt 4702
Sfmt 4702
accordance with the manufacturer
installation and operation manuals.
Paragraphs (5)(a) through (b) of this section
provide specifications for addressing key
information typically found in the
installation and operation manuals.
(a) If a manufacturer specifies a range of
superheat, sub-cooling, and/or refrigerant
pressure in its installation and operation
manual for a given basic model, any value(s)
within that range may be used to determine
refrigerant charge or mass of refrigerant,
unless the manufacturer clearly specifies a
rating value in its installation and operation
manual, in which case the specified rating
value shall be used.
(b) The air flow rate used for testing must
be that set forth in the installation and
operation manuals being shipped to the
commercial customer with the basic model
and clearly identified as that used to generate
the DOE performance ratings. If a certified air
flow value for testing is not clearly identified,
a value of 400 standard cubic feet per minute
(scfm) per ton shall be used.
(6) Indoor airflow testing and adjustment.
(i) When testing full-capacity cooling
operation at the required external static
pressure condition, the full-load indoor
airflow rate must be within +/¥5 percent of
the certified-rated airflow at full-capacity
cooling operation. If the indoor airflow rate
at the required minimum external pressure is
outside the +/¥5 percent tolerance, the unit
and/or test setup must be adjusted such that
both the airflow and ESP are within the
required tolerances. This process may
include, but is not limited to, adjusting any
adjustable motor sheaves, adjusting variable
drive settings, or adjusting the code tester
fan.
(ii) When testing other than full-capacity
cooling operation using the full-load indoor
airflow rate (e.g., full-load heating), the fullload indoor airflow rate must be within
+/¥5 percent of the certified-rated full-load
cooling airflow (without regard to the
resulting external static pressure), unless the
unit is designed to operate at a different
airflow for cooling and heating mode. If
necessary, a test facility setup may be made

Federal Register / Vol. 80, No. 151 / Thursday, August 6, 2015 / Proposed Rules
in order to maintain air flow within the
required tolerance; however, no adjustments
to the unit under test may be made.
(7) Condenser head pressure controls.
Condenser head pressure controls of
commercial unitary air conditioners and
commercial unitary heat pumps, if typically
shipped with units of the basic model by the
manufacturer or available as an option to the
basic model, must be active during testing.
(8) Standard CFM. In the referenced
sections of ANSI/AHRI 340/360–2007 for
commercial unitary air conditioners and
commercial unitary heat pumps, all instances
of CFM refer to standard CFM (SCFM).
Likewise, all references to airflow or air
quantity refer to standard airflow and
standard air quantity.
(9) Capacity rating at part-load. When
testing commercial unitary air conditioners
and commercial unitary heat pumps to
determine EER for the part-load rating points
(i.e. 75 percent load, 50 percent load, and 25
percent load), if the measured capacity
expressed as a percent of full load capacity
for a given part-load test is within three
percent above or below the target part-load
percentage, the EER calculated for the test
may be used without any interpolation to
determine IEER.

RIN 1904-AD54
Energy Conservation Program: Test Procedures for Small, Large,
and Very Large Air-Cooled Commercial Package Air Conditioning and
Heating Equipment
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: In this notice of proposed rulemaking (NOPR), the U.S.
Department of Energy (DOE) proposes to reaffirm that the currently
prescribed test procedure must be used when measuring the energy
efficiency ratio, integrated energy efficiency ratio, and coefficient
of performance for small, large, and very large air-cooled commercial
unitary air conditioners (CUAC) and commercial unitary heat pumps
(CUHP). With this test procedure rulemaking, DOE fulfills its
obligation under EPCA to review its test procedures for covered
equipment at least once every seven years and either amend the
applicable test procedures or publish a determination in the Federal
Register not to amend them. The proposed amendments would limit the
incorporation by reference of the industry test procedure AHRI Standard
340/360-2007, ``2007 Standard for Performance Rating of Commercial and
Industrial Unitary Air-Conditioning and Heat Pump Equipment'' to
certain sections and addenda; specify requirements for indoor airflow
tolerance and adjustment to meet other rating conditions; clarify
requirements for condenser head pressure controls; clarify units of
measurement for airflow; and establish a tolerance on part-load rating
points. DOE also proposes to amend the certification, compliance, and
enforcement provisions for CUACs and CUHPs to specify additional
reporting requirements for indoor airflow and add enforcement
provisions for verifying the rated cooling capacity, as the rated
cooling capacity determines which class of equipment the product
belongs to and also determines certain testing conditions.
DATES: DOE will hold a public meeting on this proposed test procedure
if one is requested by August 13, 2015. If a public meeting is
requested, DOE will announce its date and location on the DOE Web site
and via email. The meeting will also be broadcast as a webinar. DOE
will accept comments, data, and information regarding this notice of
proposed rulemaking (NOPR) before and after any public meeting, but no
later than September 8, 2015. See section V, ``Public Participation,''
for details.
ADDRESSES: Any comments submitted must identify the NOPR for Test
Procedures for Small, Large, and Very Large Air-Cooled Commercial

I. Authority and Background
Title III of the Energy Policy and Conservation Act of 1975 (42
U.S.C. 6291, et seq.; ``EPCA'' or, ``the Act'') sets forth a variety of
provisions designed to improve energy efficiency. (All references to
EPCA in this document refer to the statute as amended through the
Energy Efficiency Improvement Act of 2015, Pub. L. 114-11 (Apr. 30,
2015).) Part C of Title III, which for editorial reasons was
redesignated as Part A-1 upon incorporation into the U.S. Code (42
U.S.C. 6311-6317, as codified), establishes the Energy Conservation
Program for Certain Commercial and Industrial Equipment. This equipment
includes small, large, and very large air-cooled commercial package air
conditioning and heating equipment--which includes commercial unitary
air conditioners (CUACs) and commercial unitary heat pumps (CUHPs), the
subjects of today's notice. (42 U.S.C. 6311(1)(B)-(D))
Under EPCA, the energy conservation program consists essentially of
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation
standards, and (4) certification and enforcement procedures. The
testing requirements consist of test procedures that manufacturers of
covered equipment must use as the basis for (1) certifying to DOE that
their equipment complies with applicable energy conservation standards
adopted under EPCA, and (2) making representations about the efficiency
of the equipment. Similarly, DOE must use these test procedures to
determine whether the equipment complies with any relevant standards
promulgated under EPCA.
General Test Procedure Rulemaking Process
In 42 U.S.C. 6314, EPCA sets forth the general criteria and
procedures DOE must follow when prescribing or amending test procedures
for covered equipment. EPCA provides in relevant part that any test
procedures prescribed or amended under this section must be reasonably
designed to produce test results which measure energy efficiency,
energy use or estimated annual operating cost of a covered product
during a representative average use cycle or period of use and must not
be unduly burdensome to conduct. (42 U.S.C. 6314(a)(2)) In addition, if
DOE determines that a test procedure amendment is warranted, it must
publish proposed test procedures and offer the public an opportunity to
present oral and written comments on them. (42 U.S.C. 6314(b))
DOE is also required by EPCA to conduct an evaluation of test
procedures at least every seven years for each class of covered
equipment (including CUACs and CUHPs) to determine if an amended test
procedure would more accurately or fully comply with the requirement to
be reasonably designed to produce test results that reflect the energy
efficiency, energy use, and operating costs during a representative
average use cycle. DOE must either prescribe amended test procedures or
publish a notice in the Federal Register regarding its determination
not to amend test procedures. (42 U.S.C. 6314(a)(1)-(2))
Background
DOE's test procedure for CUACs and CUHPs is codified at Title 10 of
the Code of Federal Regulations (CFR), section 431.96. The current
regulations require that manufacturers use ANSI/AHRI Standard 340/360-
2007, ``2007 Standard for Performance Rating of Commercial and
Industrial Unitary Air-Conditioning and Heat Pump Equipment''
(henceforth referred to as ANSI/AHRI 340/360-2007) when measuring the
efficiency of a given CUAC or CUHP and certifying that equipment as
compliant with the applicable standard.\1\ 77 FR 28928, 28990 (May 16,
2012).
---------------------------------------------------------------------------
\1\ DOE notes that for purposes of this notice, all references
to ANSI/ASHRAE 340/360-2007 include Addenda 1 and 2 to this
industry-based standard.
---------------------------------------------------------------------------
On February 1, 2013, DOE published a request for information and
notice of document availability regarding energy conservation standards
for CUACs and CUHPs. 78 FR 7296. The request for information solicited
information from the public to help DOE determine whether national
standards more stringent than those that are currently in place would
result in a significant amount of additional energy savings and whether
those national standards would be technologically feasible and
economically justified. DOE also sought information from the public on
the merits of adopting the integrated energy efficiency ratio (IEER) as
the energy efficiency descriptor for small, large, and very large air-
cooled commercial air conditioners and heat pumps. Currently,
manufacturers must measure the energy efficiency of their equipment
using the energy efficiency ratio (EER), which provides a measurement
of the full-load efficiency of a given unit. The procedure to follow
when measuring and calculating that value, like the proposed IEER
metric, is found in ANSI/ASHRAE
[[Page 46872]]
340/360-2007. See ANSI/ASHRAE 340/360-2007 at sec. 6. Comments received
on the topic of IEER are discussed in a related energy conservation
standards NOPR, which was published in September 2014. 79 FR 58948
(Sept. 30, 2014).
Subsequently, on April 1, 2015, DOE issued a notice of intent to
establish the Commercial Package Air Conditioners and Heat Pumps and
Commercial Warm Air Furnaces Working Group to negotiate either a notice
of proposed rulemaking (NOPR) or final rule for energy conservation
standards for this equipment. 80 FR 17363. This Working Group was
established under the Appliance Standards and Rulemaking Federal
Advisory Committee (ASRAC) in accordance with the Federal Advisory
Committee Act and the Negotiated Rulemaking Act. See 5 U.S.C.
Appendix--Federal Advisory Committee Act and 5 U.S.C. 561-570a. The
Working Group, which consisted of 17 members, including one member from
ASRAC and one DOE representative, met six times (five times in-person
and once by teleconference). The meetings were held on April 28, May
11-12, May 20-21, June 1-2, June 9-10, and June 15, 2015. The Working
Group successfully reached consensus on energy conservation standards
for commercial package air conditioners and heat pumps and commercial
warm air furnaces, which included the Working Group's recommendations
to ASRAC on the energy conservation standards. The group also chose to
provide test procedure and metric-related recommendations to the
committee. ASRAC voted unanimously to approve the Working Group's
recommendations on June 17, 2015. Consistent with those
recommendations, DOE proposes to amend the test procedure and
associated certification regulations for small, large, and very large
air-cooled commercial package air conditioning and heating equipment to
implement the Working Group's recommendations. Participants in the
Working Group consisted of the following entities aside from DOE:

DOE considers the activity associated with this rulemaking
sufficient to satisfy the statutory requirement that DOE review its
test procedures for all covered equipment, including CUACs and CUHPs,
at least once every seven years and either amend the applicable test
procedures or publish a determination in the Federal Register not to
amend them. (42 U.S.C. 6314(a)(1))
II. Summary of the Notice of Proposed Rulemaking
DOE is proposing several amendments to its regulations related to
the test procedures prescribed for CUACs and CUHPs in 10 CFR part 431,
subpart F. First, DOE proposes to amend the current DOE test procedure
to incorporate only certain sections of ANSI/AHRI 340/360-2007 rather
than in its entirety. Second, DOE proposes amendments to incorporate a
tolerance on the indoor airflow rate. In particular, during full load
testing in cooling mode, the indoor airflow rate would be required to
remain within +/-5 percent of the rated full-load indoor airflow. The
unit and/or test facility must be adjusted to maintain this tolerance
for indoor airflow rate while ensuring that the ESP remains within the
tolerance required by the test procedure. For any other condition using
full-load airflow (e.g. full-load heating for a heat pump), the +/-5
percent tolerance would also apply and, if necessary, a test facility
adjustment would be made in order to maintain air flow within the
required tolerance, but the unit itself may not be adjusted. Third, DOE
proposes to clarify that condenser head pressure controls, if included
with the unit, must be active during testing. Fourth, DOE proposes to
clarify that reference to cubic feet per minute (CFM) in ANSI/AHRI 340/
360-2007 must be interpreted as referring to standard CFM (SCFM).
Fifth, DOE proposes that when conducting part-load testing to measure
IEER, the difference between the percent load calculated for a part-
load test point and its target value may be as much as three percent
without requiring interpolation or application of the cyclic
degradation factor specified in ANSI/AHRI 340/360-2007. Sixth, DOE
proposes to amend the certification, compliance, and enforcement
provisions for CUACs and CUHPs. These amendments include adding
enforcement provisions for verifying the cooling capacity, as the
cooling capacity determines which class of equipment the product
belongs to and also determines certain testing conditions. Lastly, DOE
has proposed a definition of integrated energy efficiency ratio (IEER).
DOE believes that none of these clarifications or amendments would
result in any changes to the energy efficiency of current equipment.
Representations of energy efficiency metrics would be required to be
based on the amended test procedure beginning 360 days after the date
of publication of the final rule. 42 U.S.C. 6314(d) (prescribing a 360-
day period after a test procedure's publication by which manufacturer
representations of energy consumption or energy costs must be based on
that procedure).

III. Discussion
A. Amendments to the Current DOE Test Procedure
DOE proposes making several amendments to the current DOE test
procedure, which incorporates ANSI/AHRI 340/360-2007 by reference.
These amendments are detailed below.
1. Sections of ANSI/AHRI 340/360-2007 Incorporated by Reference
Currently, 10 CFR 431.96, Table 2, specifies that when measuring
the energy efficiency of CUACs and CUHPs using the metrics EER and
coefficient of performance (COP), ANSI/AHRI 340/360-2007 must be used,
but omitting section 6.3 of that industry testing standard. DOE
proposes that when testing CUACs and CUHPs using the EER, COP, and IEER
metrics, only certain sections of ANSI/AHRI 340/360-2007 are required,
specifically sections 3, 4, and 6 (but, again, omitting section 6.3),
rather than applying the entirety of ANSI/AHRI 340/360-2007. The
sections DOE proposes to incorporate are those that include the
relevant testing provisions that apply directly to the DOE test
procedure, while the excluded sections contain provisions unrelated to
the DOE test procedure. DOE proposes not to incorporate section 5 of
ANSI/AHRI 340/360-2007, which consists of a single sentence referring
to use of ASHRAE 37, ``Methods of Testing for Rating Unitary Air-
Conditioning and Heat Pump Equipment,'' for test methods and
procedures. DOE proposes this change because the version of this test
method is not specified. Instead, DOE proposes to incorporate by
reference the most recent version of this test procedure--ANSI/ASHRAE
37-2009. The test standard would be listed in 10 CFR 431.95, and
incorporated by reference in 10 CFR 431.96. In case of a conflict
between ANSI/AHRI 340/360-2007 or ANSI/ASHRAE 37-2009 and the CFR, the
CFR provisions control.
2. Indoor Airflow Adjustment and Reporting
Section 6.1.3.2 of ANSI/AHRI 340/360-2007 establishes minimum
external static pressure (ESP) rating requirements for different
equipment capacities and requirements for the indoor-coil airflow rate
for determining standard ratings. DOE notes that AHRI 340/360 also
refers to ESP as ``external pressure'' and ``external resistance.''
Section 6.1.3.2 establishes a tolerance of -0 in. H2O to
+0.05 in. H2O for ESP (i.e., the measured ESP may not be any
lower but can be up to 0.05 in. H2O higher than the required
minimum) but does not contain a tolerance for the airflow rate.
Manufacturers are currently required to report, among other
information, the model number and specifications of the motor and the
drive kit, including settings, associated with that specific motor that
were used to determine the certified rating; as well as the rated
airflow in SCFM for each fan coil; in the supplemental information
submitted with the certification report for the unit. (See 10 CFR
429.43(b)(4)(i))
DOE proposes that any subsequent testing (e.g., DOE assessment and
enforcement testing) must use the same motor and drive assembly and
settings specified in the certification information, and that the party
conducting testing would be required to ensure that the ESP is within
the tolerances set forth in Section 6.1.3.2 of ANSI/AHRI 340/360-2007
and must verify that the indoor airflow rate is within +/-5 percent of
the manufacturer-rated full-load indoor airflow rate. If the indoor
airflow in SCFM measured at the required ESP is outside the +/-5
percent tolerance, the unit and/or test facility must be adjusted to
set up the unit such that both the airflow and ESP are within the
required tolerances. This process may include, but is not limited to,
adjusting any adjustable motor sheaves, adjusting variable frequency
drive (VFD) settings, or adjusting the code tester fan. DOE believes
that the proposed 5 percent tolerance on airflow is an appropriate
compromise of test burden and precision because holding this tolerance
has been possible without difficulty in DOE's own testing, and because
testing and analysis shows that the impact of up to 5 percent airflow
rate variation on capacity and IEER is minimal. For example, DOE
testing of a 7.5-ton CUAC unit suggested that 5 percent variation in
the full-load airflow would cause 0.5 percent variation in EER and 0.8
percent variation in capacity. DOE also used data available in
manufacturer data sheets to calculate IEER as a function of indoor
airflow for several commercial air conditioners and determined that a 5
percent variation in airflow would be expected to cause, on average, a
1.5 percent variation in IEER. (See EERE-2015-BT-TP-0015.) DOE requests
comment on the appropriateness of the +/-5 percent tolerance and/or
data that might show that a different tolerance level might be more
appropriate. This is Issue 1 in section V.B, ``Issues on Which DOE
Seeks Comment.''
ANSI/AHRI 340/360-2007, section 6.1.3.2.e specifies that the full-
load cooling airflow rate must be employed for any other condition
using full-load air flow (e.g., full-load heating) without regard to
resulting ESP. DOE proposes that the +/-5 percent tolerance for air
flow rate must be applied for these other conditions as well. If
necessary, a test facility adjustment may have to be made in order to
maintain air flow within the required tolerance; for example,
adjustment of the code tester fan may be needed to ensure air flow
within the specified tolerance range even if the ESP is no longer
within the range specified for operation in full-capacity cooling mode.
(In this situation, the tester would not adjust the unit under test.)
DOE requests comments on this interpretation and clarification of the
requirements of ANSI/AHRI 340/360-2007, section 6.1.3.2.e, regarding
operation in modes other than full-capacity cooling. This is Issue 2 in
section V.B, ``Issues on Which DOE Seeks Comment.''
DOE realizes that some units may be designed to operate with a
different indoor airflow rate for cooling or heating mode, such as when
the unit incorporates variable speed indoor fans. In that case, DOE
proposes that manufacturers would report the individual indoor airflow
rates in cooling and heating mode. DOE is proposing this approach in
order to capture air flow rates used in the different full-load tests
(i.e., heating and cooling). DOE requests comment on whether marketed
units actually operate in this manner, and if so, whether this proposed
provision would be appropriate for such units. This is Issue 3 in
section V.B, ``Issues on Which DOE Seeks Comment.''
DOE also proposes that a manufacturer must include in its
certification report the adjusted indoor airflow at each part-load
condition. Inclusion of these part-load air flow rates would allow
confirmation that, during any subsequent third-party testing, the
equipment is operating at part-load as rated.
3. Condenser Head Pressure Controls
Note 2 of Table 6 of ANSI/AHRI 340/360-2007 specifies that
condenser airflow should be adjusted as required by the unit controls
for head pressure control. Condenser head pressure controls regulate
the flow of refrigerant through the condenser and/or adjust operation
of condenser fans to prevent condenser pressures from dropping too low
during low-ambient operation. When employed, these controls ensure that
the refrigerant pressure is high enough to maintain adequate flow
through refrigerant expansion devices such as thermostatic expansion
valves. The use of condenser head pressure controls influences a unit's
performance, making it important that
[[Page 46874]]
this feature be operating during the test because it would be operating
in the field. DOE proposes to specify that condenser head pressure
controls, if included with the unit, must be active during testing.
The use of condenser head pressure controls may prevent a unit from
reaching steady state prior to testing. For example, a unit employing
condenser head pressure control might cycle a condenser fan to control
head pressure. The current DOE test procedure does not address such
operation. Hence, if a unit with condenser head pressure controls
cannot achieve steady-state operation with the controls active, and
thus cannot be tested, the manufacturer would have to request a waiver.
See 10 CFR 431.401 (``Any interested person may submit a petition to
waive for a particular basic model the requirements of any uniform test
method contained in this part, upon the grounds that . . . the basic
model contains one or more design characteristics that prevent testing
of the basic model according to the prescribed test procedures.'') DOE
requests comment on whether there are any units sold for which this
might occur and what changes, if any, may be needed to DOE's proposal
to address this scenario. This is Issue 4 in section V.B, ``Issues on
Which DOE Seeks Comment.''
4. Unit of Measurement for Airflow
ANSI/AHRI 340/360-2007 lacks clarity regarding references to CFM as
opposed to SCFM. In order to resolve this, DOE proposes that all
instances of CFM as a unit of airflow must be interpreted to mean SCFM
where they appear in the sections of ANSI/AHRI 340/360-2007
incorporated by reference in 10 CFR part 431, subpart F.
5. Tolerance on Percent Load for IEER Part-Load Tests
For calculating IEER, section 6.2.2 of ANSI/AHRI 340/360-2007
specifies that the unit efficiency must be determined at 100 percent,
75 percent, 50 percent, and 25 percent load (defined as part-load net
cooling capacity divided by full-load net cooling capacity, then
multiplied by 100 percent) at the conditions specified in Table 6 of
ANSI/AHRI 340/360-2007 (Table 6). ANSI/AHRI 340/360-2007 also provides
instruction for when a unit cannot operate at the 75 percent, 50
percent, and 25 percent part-load test points, but does not specify a
tolerance for the percent load, i.e. how much can the load deviate from
the part-load test point and still be considered operating at the part-
load test point. For example, if the calculated percent load for one of
the part-load tests is 75.5 percent, are the results of this test
acceptable for use as the 75 percent part-load test point condition?
DOE proposes to apply a +/-3 percent tolerance to each part load
test point. In other words, the difference between the percent load
calculated for a part-load test point and its target value may be as
much as 3 percent and still be considered to be operating at the target
part-load test point. DOE anticipates that this proposal will reduce
testing time and burden by eliminating additional part-load tests in
cases where operation closely approaches but does not exactly meet the
target part-load test points. DOE requests comment on establishing this
tolerance and on the appropriateness of the proposed tolerance level.
This is Issue 5 in section V.B, ``Issues on Which DOE Seeks Comment.''
B. Certification and Enforcement Issues
1. Measuring Cooling Capacity for Purposes of Certification,
Assessment, and Enforcement
Manufacturers must certify and report CUAC and CUHP cooling
capacity (in Btu/h) when certifying the efficiency of this equipment,
per 10 CFR 429.43(b)(2). The cooling capacity represented by
manufacturers for certification and compliance purposes must be
determined through testing in accordance with 10 CFR 431.96. DOE
proposes that the cooling capacity certified to DOE for a given basic
model must be the average of the capacities measured for the sample of
units tested to certify that basic model, rounded according to the
multiples in Table 4 in ANSI/AHRI 340/360-2007.
DOE proposes that when conducting assessment and enforcement
testing, the total cooling capacity must be measured pursuant to the
test requirements of 10 CFR 431.96 for each unit tested, and the
results of the measurement(s) (either the measured cooling capacity for
a single unit sample or the average of the measured cooling capacities
for a multiple-unit sample) compared to the value of cooling capacity
certified by the manufacturer. The manufacturer-certified cooling
capacity will be considered valid if the cooling capacity determined
through DOE testing is within five percent of the certified cooling
capacity.
2. Compliance Dates of the Test Procedure Amendments
In amending a test procedure for small, large, or very large
commercial package air conditioning and heating equipment, EPCA directs
DOE to determine to what extent, if any, the test procedure would alter
the measured energy efficiency or measured energy use of a covered
product. (42 U.S.C. 6314(a)(4)) If the amended test procedure alters
the measured energy efficiency or measured energy use, the Secretary
must amend the applicable energy conservation standard accordingly. (42
U.S.C. 6314(a)(4) (requiring that the provisions of 42 U.S.C. 6293(e),
which includes determining the impact that changes to a test procedure
would have on the measured energy efficiency or energy use of a covered
product))
In DOE's view, no aspect of this NOPR is likely to alter the
measured efficiency of CUACs and CUHPs. These proposed amendments,
which follow the Working Group's recommendations, relate to DOE's
efforts to establish amended energy conservation standards for CUACs
and CUHPs. As part of that standards rulemaking effort, DOE had
proposed, and the Working Group adopted, an approach that would base
the amended standards for this equipment on IEER instead of EER. See 79
FR 58947 at 58956 (September 30, 2014); ASRAC Commercial Package Air
Conditioners and Commercial Warm Air Furnaces Working Group Term Sheet,
at 2 (June 15, 2015). DOE has also proposed a definition of IEER to
support the Working Group's approach. Consistent with this transition
to IEER as the reporting metric for this equipment, DOE proposes to
require the reporting of indoor part-load airflow rates used in the
IEER calculation as of the compliance date of the new standard. DOE
also proposes another amendment associated with the measurement of
IEER--applying a +/- 3 percent tolerance to each part-load test point
for IEER ratings. This proposed amendment, if adopted, would be
required as of the compliance date of the new standard.
The proposed amendments not specifically related to IEER would,
rather than alter the measured efficiency or measured energy use of
CUAC and CUHP equipment, clarify how to test this equipment. These
proposed amendments would limit the incorporation by reference of ANSI/
AHRI 340/360-2007 to certain sections, establish a tolerance on full-
load indoor airflow, add condenser head pressure control requirements,
and clarify units of measurement for airflow. These proposals, if
adopted, would result in no procedural changes related to how testing
would be performed. These proposed amendments, if adopted,
[[Page 46875]]
would become effective 30 days after publication of the final rule in
the Federal Register. Consistent with 42 U.S.C. 6314(d), any
representations of energy consumption of CUACs and CUHPs must be based
on any final amended test procedures 360 days after the publication of
the test procedure final rule.
IV. Procedural Issues and Regulatory Review
A. Review Under Executive Order 12866
The Office of Management and Budget (OMB) has determined that test
procedure rulemakings do not constitute ``significant regulatory
actions'' under section 3(f) of Executive Order 12866, Regulatory
Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this
action was not subject to review under the Executive Order by the
Office of Information and Regulatory Affairs (OIRA) in the Office of
Management and Budget.
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) 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 Executive Order 13272, ``Proper Consideration of Small
Entities in Agency Rulemaking,'' 67 FR 53461 (August 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 DOE rulemaking process. 68 FR 7990. DOE has made
its procedures and policies available on the Office of the General
Counsel's Web site: https://energy.gov/gc/office-general-counsel.
DOE reviewed today's proposed rule under the provisions of the
Regulatory Flexibility Act and the procedures and policies published on
February 19, 2003. This proposed rule prescribes test procedures that
will be used to test compliance with energy conservation standards for
the equipment that are the subject of this rulemaking. DOE has
tentatively concluded that the proposed rule would not have a
significant impact on a substantial number of small entities.
For manufacturers of small, large, and very large air-cooled CUAC
and CUHP, the Small Business Administration (SBA) has set a size
threshold, which defines those entities classified as ``small
businesses'' for the purposes of the statute. DOE used the SBA's small
business size standards to determine whether any small entities would
be subject to the requirements of the rule. 65 FR 30836, 30848 (May 15,
2000), as amended at 65 FR 53533, 53544 (Sept. 5, 2000) and codified at
13 CFR part 121. The size standards are listed by North American
Industry Classification System (NAICS) code and industry description
and are available at https://www.sba.gov/category/navigation-structure/contracting/contracting-officials/small-business-size-standards.
Manufacturing of small, large, and very large air-cooled CUAC and CUHP
is classified under NAICS 333415, ``Air-Conditioning and Warm Air
Heating Equipment and Commercial and Industrial Refrigeration Equipment
Manufacturing.'' The SBA sets a threshold of 750 employees or less for
an entity to be considered as a small business for this category. DOE
initially identified 12 potential manufacturers of commercial packaged
air conditioners sold in the U.S. DOE then determined that 10 were
large manufacturers, manufacturers that are foreign-owned and -
operated, or manufacturers that do not produce products covered by this
rulemaking. DOE was able to determine that 2 manufacturers meet the
SBA's definition of a ``small business'' and manufacture products
covered by this rulemaking.
DOE expects the impact of the proposed rule on manufacturers,
including small businesses, to be minimal. The proposed rule would
amend DOE's certification requirements to specify additional reporting
requirements and add enforcement provisions for verifying cooling
capacity. The proposed rule would also clarify or amend DOE's test
procedures to amend AHRI Standard 340/360-2007, ``2007 Standard for
Performance Rating of Commercial and Industrial Unitary Air-
Conditioning and Heat Pump Equipment,'' to incorporate certain sections
by reference, specify requirements for airflow adjustment and tolerance
to meet other rating conditions, require units with condenser head
pressure controls to be tested with those controls active, clarify the
unit of measurement for airflow, and establish a tolerance on part-load
rating points.
The Working Group has recommended amended energy conservation
standards rulemaking that the standards will be based on the metric of
integrated energy efficiency ratio (IEER) instead of energy efficiency
ratio (EER). DOE expects the impact on test burden to be modest. AHRI
ratings already include IEER, indicating that many manufacturers,
representing a large portion of the market, already determine IEER for
their units. ANSI/ASHRAE/IES Standard 90.1-2013--Energy Standard for
Buildings Except Low-Rise Residential Buildings (ASHRAE 90.1-2013) has
adopted an IEER requirement, which makes reporting of IEER necessary
for shipment to those states and localities that will adopt that
standard in building codes. Current procedures relating to alternative
efficiency determination methods (AEDMs), including procedures for
certifying IEER, require a limited amount of testing to be conducted
when validating an AEDM for CUACs and CUHPs. 10 CFR 429.70(c)(2)(iv)
(detailing the minimum number of distinct basic models required to be
test for purposes of AEDM validation for different equipment types and
classes) . DOE expects that most CUAC and CUHP ratings will be based on
results obtained from AEDMs. Although DOE recognizes that some ratings
will be based on testing, DOE expects these ratings to comprise a small
minority of products.
However, to help DOE better understand the burdens when measuring
IEER instead of EER, DOE requests comment and data on manufacturer
expectations of the number of models that will likely be tested rather
than rated with an AEDM. DOE encourages confidential data submissions
if necessary in order to ensure that such data can be provided.
For these reasons, DOE certifies that this proposed rule would not
have a significant economic impact on a substantial number of small
entities. Accordingly, DOE has not prepared a regulatory flexibility
analysis for this rulemaking. DOE will transmit the certification and
supporting statement of factual basis to the Chief Counsel for Advocacy
of the SBA for review under 5 U.S.C. 605(b).
C. Review Under the Paperwork Reduction Act of 1995
Manufacturers of small, large, and very large air-cooled CUAC and
CUHP equipment must certify to DOE that their equipment complies with
any applicable energy conservation standards. In certifying compliance,
manufacturers must test their equipment according to the appropriate
DOE test procedures for this equipment, including any applicable
amendments. DOE has established regulations for the certification and
recordkeeping requirements for all covered consumer products and
commercial equipment, including CUACs and CUHPs. See 10
[[Page 46876]]
CFR part 429, subpart B. The collection-of-information requirement for
the certification and recordkeeping is subject to review and approval
by OMB under the Paperwork Reduction Act (PRA).
In the Certification of Commercial Equipment Final Rule published
in May 2014, DOE amended existing regulations governing compliance
certification for a variety of commercial equipment covered by EPCA,
which affected CUAC and CUHP manufacturers. 79 FR 25486 at 25502 (May
5, 2014). In today's NOPR, DOE proposes to amend its certification
requirements to specify additional reporting requirements. DOE does not
believe that these additions to the certification requirements
constitute a significant additional burden upon respondents, as they
require minimal additional information to what manufacturers must
already report in their certification reports. DOE believes that the
Certification of Commercial Equipment Final Rule provides an accurate
estimate of the existing burden on respondents and would continue to
apply to the relevant aspects of the proposed amendments. See 79 FR at
25496-25498 (detailing burden estimates and indicating an average
burden of approximately 30 hours per company on an annual basis). OMB
has approved the revised information collection for DOE's certification
and recordkeeping requirements. 80 FR 5099 (January 30, 2015).
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
In this proposed rule, DOE proposes test procedure amendments that
it expects will be used to develop and implement future energy
conservation standards for commercial unitary air conditioners and
commercial unitary heat pumps. DOE has determined that this rule falls
into a class of actions that are categorically excluded from review
under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et
seq.) and DOE's implementing regulations at 10 CFR part 1021.
Specifically, this proposed rule would amend the existing test
procedures without affecting the amount, quality or distribution of
energy usage, and, therefore, would not result in any environmental
impacts. Thus, this rulemaking is covered by Categorical Exclusion A5
under 10 CFR part 1021, subpart D, which applies to any rulemaking that
interprets or amends an existing rule without changing the
environmental effect of that rule. Accordingly, neither an
environmental assessment nor an environmental impact statement is
required.
E. Review Under Executive Order 13132
Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4, 1999)
imposes certain requirements on 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 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 proposed 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
equipment that is the subject of today's proposed 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(d)) No further
action is required by Executive Order 13132.
F. Review Under Executive Order 12988
Regarding the review of existing regulations and the promulgation
of new regulations, section 3(a) of Executive Order 12988, ``Civil
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), 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. Section 3(b) of Executive Order 12988
specifically requires that Executive agencies make every reasonable
effort to ensure that the regulation: (1) Clearly specifies 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 Executive Order 12988 requires Executive
agencies to review regulations in light of applicable standards in
sections 3(a) and 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,
the proposed rule meets the relevant standards of Executive Order
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 proposed 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 proposed ``significant
intergovernmental mandate,'' and requires an agency plan for giving
notice and opportunity for timely input to potentially affected small
governments before establishing any requirements that might
significantly or uniquely affect small governments. On March 18, 1997,
DOE published a statement of policy on its process for
intergovernmental consultation under UMRA. 62 FR 12820; also available
at https://energy.gov/gc/office-general-counsel. DOE examined this
proposed rule according to UMRA and its statement of policy and
determined that the proposed rule contains neither an intergovernmental
mandate, nor a mandate that may result in the expenditure of $100
million or more in
[[Page 46877]]
any year, so these requirements do not apply.
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.
This rule would not have any impact on the autonomy or integrity of the
family as an institution. Accordingly, DOE has concluded that it is not
necessary to prepare a Family Policymaking Assessment.
I. Review Under Executive Order 12630
DOE has determined, under Executive Order 12630, ``Governmental
Actions and Interference with Constitutionally Protected Property
Rights'' 53 FR 8859 (March 18, 1988), that this regulation would not
result in any takings that might require compensation under the Fifth
Amendment to the U.S. Constitution.
J. Review Under 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 agencies to review most
disseminations of information to the public under 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). DOE has
reviewed today's proposed 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
Executive Order 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 OMB,
a Statement of Energy Effects for any proposed significant energy
action. A ``significant energy action'' is defined as any action by an
agency that promulgated 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 proposed significant energy action,
the agency must give a detailed statement of any 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.
Today's regulatory action to amend the test procedure for measuring
the energy efficiency of CUACs and CUHPs is not a significant
regulatory action under Executive Order 12866. Moreover, it would not
have a significant adverse effect on the supply, distribution, or use
of energy, nor has it been designated as a significant energy action by
the Administrator of OIRA. Therefore, it is not a significant energy
action, and, accordingly, DOE has not prepared a Statement of Energy
Effects.
L. Review Under Section 32 of the Federal Energy Administration Act of
1974
Under section 301 of the Department of Energy Organization Act
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the
Federal Energy Administration Act of 1974, as amended by the Federal
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA)
Section 32 essentially provides in relevant part that, where a proposed
rule authorizes or requires use of commercial standards, the notice of
proposed rulemaking must inform the public of the use and background of
such standards. In addition, section 32(c) requires DOE to consult with
the Attorney General and the Chairman of the Federal Trade Commission
(FTC) concerning the impact of the commercial or industry standards on
competition.
The proposed rule incorporates testing methods contained in the
following commercial standards: ANSI/AHRI Standard 340/360-2007 and
ANSI/ASHRAE Standard 37-2009. The Department has evaluated these
standards and is unable to conclude whether they fully comply with the
requirements of section 32(b) of the FEAA, (i.e., that they were
developed in a manner that fully provides for public participation,
comment, and review). DOE will consult with the Attorney General and
the Chairman of the FTC concerning the impact of these test procedures
on competition, prior to prescribing a final rule.
M. Description of Materials Incorporated by Reference
DOE is proposing to incorporate by reference ANSI/AHRI Standard
340/360-2007 (with Addenda 1 and 2), ``2007 Standard for Performance
Rating of Commercial and Industrial Unitary Air-Conditioning and Heat
Pump Equipment.'' This is an industry-accepted standard used by
manufacturers when testing and rating the performance of commercial and
industrial unitary air-conditioning and heat pump equipment. Copies of
this testing standard are available for download at https://www.ahrinet.org/App_Content/ahri/files/standards%20pdfs/ANSI%20standards%20pdfs/ANSI%20AHRI%20Standard%20340-360-2007%20with%20Addenda%201%20and%202.pdf.

B. Issues on Which DOE Seeks Comment
Although DOE welcomes comments on any aspect of this proposal, DOE
is particularly interested in receiving comments and views of
interested parties concerning the following issues:
1. DOE proposes that when conducting full-load cooling tests with
the appropriate external static pressure (ESP) condition in Table 5 of
ANSI/AHRI 340/360-2007, the tester must use the motor and drive kit
that was used to determine the certified rating, as specified in the
manufacturer's certification information. During such testing, the
indoor airflow must be within +/-5 percent of the manufacturer's rated
full-load indoor airflow rate. If the indoor airflow at the required
ESP is outside the +/-5 percent tolerance, make necessary adjustments
to the test setup and/or the unit such that both the airflow and ESP
are within the required tolerances. DOE requests comment on the
appropriateness of the +/-5 percent tolerance and/or data showing that
a different tolerance level might be more appropriate, as well as
feedback on the burden of maintaining airflow within the tolerance. See
section III.A.2 for details.
2. Section 6.1.3.2.e of ANSI/AHRI 340/360-2007 specifies that the
full-load cooling airflow rate must be maintained for any other
condition using full-load air flow (e.g., full-load heating) without
regard to resulting ESP. DOE proposes that in this situation, the +/-5
percent tolerance on the full-load cooling airflow rate must also
apply. To maintain the airflow within the required tolerance, the
tester may make adjustments to the test facility or apparatus, but not
the unit being tested. DOE requests comments on this interpretation and
clarification of the requirements of section 6.1.3.2.e of ANSI/AHRI
340/360-2007 regarding operation in modes other than full-capacity
cooling. See section III.A.2 for details.
3. For all units, certification requirements already include
reporting of the indoor airflow at full capacity cooling operation. If
units are designed to operate with a different indoor airflow for
cooling and heating mode, DOE proposes that manufacturers would
separately report the indoor airflow in cooling and heating mode. DOE
requests comment on whether this approach is appropriate and also
requests comment on whether any units in the market are designed to
operate with a different full-load air flow for heating and cooling
modes. See section III.A.2 for details.
4. DOE proposes that condenser head pressure controls, if included
in a unit, must be active during testing. DOE requests comment on
whether there are any units on the market with condenser head pressure
controls that would prevent the unit from achieving steady state under
the test conditions. If so, how should DOE address these kinds of units
for testing purposes? See section III.A.3 for details.
5. For calculating IEER, section 6 of ANSI/AHRI 340/360-2007
specifies that the unit efficiency must be determined at 100 percent,
75 percent, 50 percent, and 25 percent load (defined as net part-load
cooling capacity divided by full-load net cooling capacity times 100
percent). ANSI/AHRI 340/360-2007 also provides instruction for when a
unit cannot operate at the 75 percent, 50 percent, and 25 percent part-
load test points, but does not specify a tolerance for the percent
load, i.e. how much can the load deviate from the part-load test point
and still be considered operating at the part-load test point. DOE
proposes to apply a +/-3 percent tolerance on the percent load for
approach to each part-load rating point. In other words, the difference
between the percent load calculated for a part-load test point and its
target value may be as much as 3 percent and still be considered to be
[[Page 46879]]
operating at the target part-load test point. DOE requests comment on
the appropriateness of the tolerance level. See section III.A.5 for
details.

to Sec. 431.96 as it now appears or Table 1 to Sec. 431.96 as it
appeared at 10 CFR part 431, subpart F, in the 10 CFR parts 200 to
499 edition revised as of January 1, 2015. After [DATE 360 DAYS
AFTER DATE OF PUBLICATION OF THE FINAL RULE], representations with
respect to energy use or efficiency of commercial unitary air
conditioners and heat pumps (CUACs and CUHPs), including compliance
certifications, must be based on testing conducted in accordance
with Table 1 to Sec. 431.96.
(1) Cooling mode test method. The test method for testing
commercial unitary air conditioners and commercial unitary heat
pumps in cooling mode must consist of application of the methods and
conditions in ANSI/AHRI 340/360-2007 sections 3, 4, and 6 (omitting
section 6.3) (incorporated by reference; see Sec. 431.95), and in
ANSI/ASHRAE 37-2009 (incorporated by reference; see Sec. 431.95).
In case of a conflict between ANSI/AHRI 340/360-2007 or ANSI/ASHRAE
37-2009 and the CFR, the CFR provisions control.
(2) Heating mode test method. The test method for testing
commercial unitary heat pumps in heating mode must consist of
application of the methods and conditions in ANSI/AHRI 340/360-2007
sections 3, 4, and 6 (omitting section 6.3) (incorporated by
reference; see Sec. 431.95), and in ANSI/ASHRAE 37-2009
(incorporated by reference; see Sec. 431.95). In case of a conflict
between ANSI/AHRI 340/360-2007 or ANSI/ASHRAE 37-2009 and the CFR,
the CFR provisions control.
(3) Minimum External Static Pressure. Use the certified cooling
capacity for the basic model to choose the minimum external static
pressure found in table 5 of section 6 of ANSI/AHRI 340/360-2007 for
testing.
(4) Optional Break-in Period. Manufacturers may optionally
specify a ``break-in'' period, not to exceed 20 hours, to operate
the equipment under test prior to conducting the test method in
appendix A. A manufacturer who elects to use an optional compressor
break-in period in its certification testing should record this
information (including the duration) as part of the information in
the supplemental testing instructions under 10 CFR 429.43.
(5) Additional Provisions for Equipment Set-up. The only
additional specifications that may be used in setting up a unit for
test are those set forth in the installation and operation manual
shipped with the unit. Each unit should be set up for test in
accordance with the manufacturer installation and operation manuals.
Paragraphs (5)(a) through (b) of this section provide specifications
for addressing key information typically found in the installation
and operation manuals.
(a) If a manufacturer specifies a range of superheat, sub-
cooling, and/or refrigerant pressure in its installation and
operation manual for a given basic model, any value(s) within that
range may be used to determine refrigerant charge or mass of
refrigerant, unless the manufacturer clearly specifies a rating
value in its installation and operation manual, in which case the
specified rating value shall be used.
(b) The air flow rate used for testing must be that set forth in
the installation and operation manuals being shipped to the
commercial customer with the basic model and clearly identified as
that used to generate the DOE performance ratings. If a certified
air flow value for testing is not clearly identified, a value of 400
standard cubic feet per minute (scfm) per ton shall be used.
(6) Indoor airflow testing and adjustment.
(i) When testing full-capacity cooling operation at the required
external static pressure condition, the full-load indoor airflow
rate must be within +/-5 percent of the certified-rated airflow at
full-capacity cooling operation. If the indoor airflow rate at the
required minimum external pressure is outside the +/-5 percent
tolerance, the unit and/or test setup must be adjusted such that
both the airflow and ESP are within the required tolerances. This
process may include, but is not limited to, adjusting any adjustable
motor sheaves, adjusting variable drive settings, or adjusting the
code tester fan.
(ii) When testing other than full-capacity cooling operation
using the full-load indoor airflow rate (e.g., full-load heating),
the full-load indoor airflow rate must be within +/-5 percent of the
certified-rated full-load cooling airflow (without regard to the
resulting external static pressure), unless the unit is designed to
operate at a different airflow for cooling and heating mode. If
necessary, a test facility setup may be made
[[Page 46882]]
in order to maintain air flow within the required tolerance;
however, no adjustments to the unit under test may be made.
(7) Condenser head pressure controls. Condenser head pressure
controls of commercial unitary air conditioners and commercial
unitary heat pumps, if typically shipped with units of the basic
model by the manufacturer or available as an option to the basic
model, must be active during testing.
(8) Standard CFM. In the referenced sections of ANSI/AHRI 340/
360-2007 for commercial unitary air conditioners and commercial
unitary heat pumps, all instances of CFM refer to standard CFM
(SCFM). Likewise, all references to airflow or air quantity refer to
standard airflow and standard air quantity.
(9) Capacity rating at part-load. When testing commercial
unitary air conditioners and commercial unitary heat pumps to
determine EER for the part-load rating points (i.e. 75 percent load,
50 percent load, and 25 percent load), if the measured capacity
expressed as a percent of full load capacity for a given part-load
test is within three percent above or below the target part-load
percentage, the EER calculated for the test may be used without any
interpolation to determine IEER.
