Federal Register/Vol. 75, No. 226/Wednesday, November 24, 2010/Proposed Rules
6314(a)(6)(E)-(F)) DOE determined that
ARI Standard 1200-2006 includes the
test procedures in ASHRAE Standard
72-2005 as well as the rating
temperatures prescribed in EPACT
2005. As a result, DOE published a final
rule on December 8, 2006 in which it
adopted ARI Standard 1200-2006,
"Performance Rating of Commercial
Refrigerated Display Merchandisers and
Storage Cabinets," as the DOE test
procedure for commercial refrigeration
equipment. 71 FR 71370; 10 CFR
431.63-431.64. ARI Standard 1200-
2006 contains rating temperature
specifications of 38 degrees Fahrenheit
(F) (+2 F) for commercial refrigerators
and refrigerator compartments, 0 OF (+2
F) for commercial freezers and freezer
compartments, and -5 OF (+2 F) for
commercial ice-cream freezers. In the
test procedure final rule, DOE adopted
a - 15 OF (+2 F) rating temperature for
commercial ice-cream freezers, rather
than the -5 OF (+2 F) prescribed in the
ARI Standard 1200-2006. During the
2006 test procedure rulemaking, DOE
determined that testing at a - 15 OF (+2
F) rating temperature was more
representative of the actual energy
consumption of commercial freezers
specifically designed for ice cream
application. 71 FR 71357. In addition,
DOE adopted AHAM Standard HRF-1-
2004, "Energy, Performance and
Capacity of Household Refrigerators,
Refrigerator-Freezers and Freezers," for
measuring compartment volumes for
equipment covered under this rule. 71
FR 71370 (Dec. 8, 2006).
Since the publication of the final rule,
ARI has merged with the Gas Appliance
Manufacturers Association (GAMA) to
form the Air-Conditioning, Heating and
Refrigeration Institute (AHRI) and
updated its test procedure, the most
recent version of which is AHRI
Standard 1200-2010. AHRI Standard
1200-2010 includes changes to the
equipment class nomenclature used in
the test procedure, the method of
normalizing equipment energy
consumption, the ice-cream freezer test
temperature, and other minor
differences. These changes aligned the
AHRI test procedure with the
nomenclature and methodology used in
DOE's 2009 standards rulemaking on
commercial refrigeration equipment.
DOE proposes to reference AHRI 1200-
2010, the test procedure currently used
in industry.
Similarly, AHAM has updated
Standard HRF-1-2004 to the most
recent version, AHAM HRF-1-2008.
The changes to this standard are mostly
editorial and involved reorganizing
some of the sections for simplicity andusability. As part of the reorganization,
the HRF-1-2004 section numbers that
are referenced within the DOE test
procedure were updated to the structure
in HRF-1-2008. However, the content
of those sections was not substantially
changed. The newly updated AHRI
Standard 1200-2010 references the most
recent version of the AHAM standard,
AHAM HRF-1-2008. As such, DOE
proposes to update the referenced test
procedure to adopt AHAM HRF-1-2008
as the prescribed method for
determining refrigerated compartment
volume.
DOE also proposes changes to the test
procedure to better address certain
energy efficiency features for which the
current test procedure cannot account.
During the 2009 energy conservation
standards rulemaking, DOE screened
out several energy efficiency
technologies because their effects were
not captured by the current test
procedure. 72 FR 41162, 41179-80 (July
26, 2007). DOE proposes modifications
to its test procedure to better address
some of these technologies. Specific
changes include provisions for
measuring the impact of night curtains
and lighting occupancy sensors and
controls.
On May 18, 2010, DOE held a public
meeting (the May 2010 Framework
public meeting) to discuss the
rulemaking framework for the
concurrent commercial refrigeration
equipment (CRE) energy conservation
standard (docket number EERE-2010-
BT-STD-0003). During this May 2010
Framework public meeting, DOE
received comments from several
interested parties that additional rating
temperatures should be considered in
the test procedure. Some equipment is
designed for storing goods such as wine,
candy, and flowers at temperatures that
are held constant, but are higher than
the temperatures typically used in
commercial refrigerators. The
commenters stated that some covered
refrigeration equipment designed for
operation at higher temperatures is not
able to be tested at the prescribed 38 F,
and they suggested that DOE consider
this in the test procedures and standards
rulemakings. Consequently, DOE
proposes provisions for testing
commercial refrigeration equipment that
is designed to operate at temperatures
higher than 38 oF at the lowest possible
application product temperature.
C. Standby Mode and Off Mode
The Energy Independence and
Security Act of 2007 (EISA 2007; Pub.
L. 110-140) amended EPCA to require
DOE, for each covered product for
which current test procedures do notaccount for standby and off mode
energy consumption, to modify the test
procedures to integrate such energy
consumption into the energy
descriptor(s) for that product, if
technically feasible. Otherwise, DOE
must prescribe a separate standby and
off mode energy use test procedure, if
technically feasible. (42 U.S.C.
6295(gg)(2)(A)) EISA 2007 also requires
any final rule to establish or revise a
standard for a covered product, adopted
after July 1, 2010, to incorporate standby
mode and off mode energy use into a
single amended or new standard, if
feasible. (42 U.S.C. 6295(gg)(3)(A)) DOE
currently believes that the "off mode"
and "standby mode" conditions of
operation do not apply to the equipment
covered by this rulemaking because the
provision within EISA which stipulates
that off mode and standby mode energy
usage must be quantified only appears
in relation to consumer products and is
not required for commercial equipment.
Additionally, commercial refrigeration
equipment, whether in retail,
foodservice, or other applications,
operates 24 hours a day, 7 days a week
to maintain product at the necessary
temperature for safe storage or retailing.
Therefore, standby and off modes will
not be considered for commercial
refrigeration equipment.
II. Summary of the Proposed Rule
DOE is considering modifications to
its test procedure to incorporate the
current industry-accepted test
procedures, address certain energy
efficiency features that currently are not
accounted for in the test procedure
(light occupancy sensors and night
curtains), and allow testing of
commercial refrigeration equipment that
cannot be tested at one of the three
currently specified product test
temperatures.
EPCA prescribes that if any
rulemaking amends a test procedure,
DOE must determine "to what extent, if
any, the proposed test procedure would
alter the measured energy efficiency
* * * of any covered product as
determined under the existing test
procedure." (42 U.S.C. 6293(e)(1);
6314(a)(6)) Further, if DOE determines
that the amended test procedure would
alter the measured efficiency of a
covered product, DOE must amend the
applicable energy conservation standard
accordingly. (42 U.S.C. 6293(e)(2);
6314(a)(6)) DOE recognizes that the
proposed test procedure amendments
would affect the measured energy use of
commercial refrigeration equipment.
DOE is considering amending the
standards currently in effect for
commercial refrigeration equipment in aconcurrent rulemaking. DOE will
