DEPARTMENT OF ENERGY

[Docket No. EERE-2007-BT-WAV-0004]


Energy Conservation Program for Consumer Products: Decision and 
Order Granting a Waiver to Cascade Group, LLC From the Department of 
Energy Residential Central Air Conditioner and Heat Pump Test Procedure 
[Case No. CAC-013]

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of 
Energy.

ACTION: Decision and Order.

-----------------------------------------------------------------------

SUMMARY: This notice announces the Department of Energy's Decision and 
Order in Case No. CAC-013, which grants a waiver to Cascade Group, LLC 
(Cascade) from the existing Department of Energy (DOE) residential 
central air conditioner and heat pump test procedure for its product 
line of residential Cascade Energy Saver (CES) multi-blower air-
conditioning and heating equipment. DOE is granting a waiver because 
the multi-blower feature of these products, which impacts the 
calculation of energy efficiency, is not accounted for in the DOE test 
procedure. As a condition of this waiver, Cascade must test and rate 
the energy consumption of specified CES products (indoor units combined 
with the listed outdoor units) according to the alternate test 
procedure set forth in this notice.

DATES: This Decision and Order is effective August 28, 2008, and will 
remain in effect until the effective date of a DOE final rule 
prescribing an amended test procedure appropriate for the model series 
of Cascade CES central air conditioners and heat pumps covered by this 
waiver.

SUPPLEMENTARY INFORMATION: In accordance with 10 CFR 430.27(l), DOE 
gives notice of the issuance of its Decision and Order as set forth 
below. In the Decision and Order, DOE grants Cascade a waiver from the 
existing residential central air conditioner and heat pump test 
procedures under 10 CFR Part 430, Subpart B, Appendix M, for its CES 
multi-indoor blower-motor products, subject to a condition requiring 
Cascade to test and rate its CES products pursuant to the alternate 
test procedure provided in this notice. DOE is granting the waiver 
because the multi-blower feature of these products, which impacts the 
calculation of energy efficiency, is not accounted for in the DOE test 
procedure. Today's Decision and Order requires that Cascade may not 
make any representations concerning the energy efficiency of these 
products unless such product has been tested in accordance with the DOE 
test procedure, consistent with the provisions and restrictions in the 
alternate test procedure as set forth in the Decision and Order below, 
and such representations fairly disclose the results of such 
testing.\1\ (42 U.S.C. 6293(c))
---------------------------------------------------------------------------

    \1\ Consistent with the statute, distributors, retailers, and 
private labelers are held to the same standard when making 
representations regarding the energy efficiency of these products. 
(42 U.S.C. 6293(c))

    Issued in Washington, DC, on August 8, 2008.

Assistant Secretary, Energy Efficiency and Renewable Energy.

Decision and Order

    In the Matter of: Cascade Group, LLC (Cascade) (Case No. CAC-013).

Background

    Title III of the Energy Policy and Conservation Act (EPCA) sets 
forth a variety of provisions concerning energy efficiency, including 
Part A \2\ of Title III which establishes the ``Energy Conservation 
Program for Consumer Products Other Than Automobiles.'' (42 U.S.C. 
6291-6309) Part A includes definitions, test procedures, labeling 
provisions, energy conservation standards, and the authority to require 
information and reports from manufacturers. Further, Part A authorizes 
the Secretary of Energy (the Secretary) to prescribe test procedures 
that are reasonably designed to produce results which measure energy 
efficiency, energy use, or estimated annual operating cost, and that 
are not unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))
---------------------------------------------------------------------------

    \2\ This part was originally titled Part B; however, it was 
redesignated Part A, after Part B of Title III was repealed by 
Public Law 109-58.
---------------------------------------------------------------------------

    Relevant to the current Petition for Waiver, the test procedures 
for residential central air conditioners and heat pumps are codified in 
10 CFR part 430, Subpart B, Appendix M. On October 22, 2007, DOE 
amended the test procedures for residential central air conditioners 
and central air conditioning heat pumps to implement test procedure 
changes for small-duct, high-velocity systems, two-capacity units, and 
to update references to the current American Society of Heating, 
Refrigerating, and Air-Conditioning Engineers (ASHRAE) standards. 72 FR 
59906. The October 22, 2007 final rule became effective on April 21, 
2008. However, these amendments did not solve the problem raised by 
Cascade in its petition.
    DOE regulations for covered products contain provisions allowing 
any interested person to seek a waiver from the test procedure 
requirements for covered consumer products when the petitioner's basic 
model contains one or more design characteristics that prevent testing 
according to the prescribed test procedures, or when the prescribed 
test procedures may evaluate the basic model in a manner so 
unrepresentative of its true energy consumption as to provide 
materially inaccurate comparative data. 10 CFR 430.27(a)(1). 
Petitioners must include in their petition any alternate test 
procedures known to evaluate the basic model in a manner representative 
of its energy consumption. (10 CFR 430.27(b)(1)(iii))
    The Assistant Secretary for Energy Efficiency and Renewable Energy 
(the Assistant Secretary) may grant a waiver subject to conditions, 
including adherence to alternate test procedures. 10 CFR 430.27(l). 
Waivers generally terminate on the effective date of a final rule which 
prescribes amended test procedures appropriate to the model series 
manufactured by the petitioner, thereby eliminating any need for the 
continuation of the waiver. 10 CFR 430.27(m).
    The waiver process contained in DOE's regulations also allows any 
interested person who has submitted a Petition for Waiver to file an 
Application for Interim Waiver of the applicable test procedure 
requirements. 10 CFR 430.27(a)(2). The Assistant Secretary will grant 
an Interim Waiver request if it is determined that the applicant will 
experience economic hardship if the Interim Waiver is denied, if it 
appears likely that the Petition for Waiver will be granted, and/or the 
Assistant Secretary determines that it would be desirable for public 
policy reasons to grant immediate relief pending a determination on the 
Petition for Waiver. 10 CFR 430.27(g). An Interim Waiver remains in 
effect for a period of 180 days or until DOE issues a determination on 
the Petition for

[[Page 50788]]

Waiver, whichever occurs first, and may be extended by DOE for 180 
days, if necessary. 10 CFR 430.27(h).
    On July 22, 2005, Cascade filed a Petition for Waiver and an 
Application for Interim Waiver from the test procedures applicable to 
its CES line of residential multi-blower air-conditioning and heating 
equipment. The DOE test procedures have provisions for central air 
conditioners with one blower and one indoor coil (the most common 
type), and for multi-splits, which have multiple refrigerant lines 
running to multiple indoor fan-coil units. The Cascade product line has 
one indoor coil with multiple blowers distributing air to a number of 
outlets. The DOE test procedure does not cover this situation, which, 
so far, is unique to Cascade's products.
    Cascade's petition requested a waiver from ARI 210/240, but this is 
not the applicable test procedure; instead, as explained below, the 
applicable test procedures are those residential test procedures 
contained in 10 CFR part 430, Subpart B, Appendix M. For the CES multi-
blower product line at issue here, all of the outdoor units involve 
single-phase equipment both for residential and commercial use. There 
is no prescribed test procedure in 10 CFR part 431, Energy Efficiency 
Program for Certain Commercial and Industrial Equipment, for single-
phase, small commercial package air-conditioning and heating equipment. 
A waiver is nonetheless required for this single-phase equipment 
because Cascade's multi-blower products are properly classified as 
``consumer products'' under 42 U.S.C. 6291(1). ``Consumer products'' 
are ones which, to a significant extent, are for personal use. Small 
commercial single-phase package air-conditioning and heating equipment 
meet this definition, given their frequent residential applications. 
(42 U.S.C. 6291(1)(B)) Thus, the Cascade CES products in question here 
require a waiver from DOE's test procedure for residential central air 
conditioners and heat pumps, under 10 CFR part 430, Subpart B, Appendix 
M.
    Cascade seeks a waiver from the applicable test procedures because 
the multi-blower feature of Cascade's equipment prevents testing 
according to the currently prescribed test procedures under 10 CFR part 
430. Consequently, Cascade has submitted an alternate test procedure to 
DOE for approval that can be used to determine the performance of its 
CES products. The alternate test procedure provides rules and 
algorithms so that, regardless of the actual number of blowers and heat 
pumps, the test procedure will model the CES system as a one-blower 
evaporator with a two-speed fan and one heat pump with one or more 
speeds.
    On April 20, 2007, DOE published in the Federal Register Cascade's 
Petition for Waiver and solicited public comments. 72 FR 19891. 
Cascade's Application for Interim Waiver was denied because it did not 
provide sufficient information to evaluate economic impact or 
competitive disadvantage or to determine public policy reasons to grant 
immediate relief. Also, DOE has never granted a waiver for a similar 
product design, so the likelihood of granting the waiver was unclear.
    DOE received one comment from Joseph A. Pietsch, P. E., which 
supported granting the waiver and Cascade's alternate test procedure 
``as an acceptable approach for rating the performance of the subject 
heat pump.''

Assertions and Determinations

Cascade's Petition for Waiver
    On July 22, 2005, Cascade submitted a Petition for Waiver and an 
Application for Interim Waiver from the test procedures applicable to 
residential and commercial air-conditioning and heating equipment, for 
its new line of CES models of central air conditioners and heat pumps. 
As explained above, only a waiver from the residential test procedure 
in 10 CFR part 430, Subpart B, Appendix M is needed.
    Cascade claims that the energy consumption of its CES systems 
cannot be accurately measured using the existing test procedures for 
the following reasons: (1) the DOE test procedure stipulates that the 
unit meet the maximum standard airflow rate of 37.5 cubic feet per 
minute (CFM)/1000 British thermal units/hour (Btu/hr); \3\ and (2) this 
CFM is applicable to an indoor unit that has only one blower-motor. The 
CES unit has from two to eight indoor blower-motors that are 
independently operating. The DOE test procedure has no guidance 
concerning the number of blowers that should be operating, the 
apportionment of the air flow among the multiple blowers, or the test 
set-up for a multi-blower system. Cascade seeks a waiver because, it 
asserts, the current procedures for testing do not apply. Therefore, 
the Cascade Petition requested that DOE grant a waiver from the 
existing test procedures until such time as a representative test 
procedure is developed and adopted for this class of products.
---------------------------------------------------------------------------

    \3\ 10 CFR part 430, Subpart B, Appendix M, section 3.1.4.1.1.
---------------------------------------------------------------------------

    In support of its petition, Cascade also submitted an alternate 
test procedure that would be applicable to all of its configurations of 
CES models of air conditioners and heat pumps. Cascade modified its 
petition on May 26, 2006, and again on April 16, 2007, after 
consultation with the National Institute of Standards and Technology 
(NIST). NIST found that there had been limitations in the original 
modeling rules, and supplied more comprehensive rules for modeling the 
CES systems. On August 15, 2007, Cascade submitted to DOE a set of 
general rules and set-up procedures to be used when testing its CES 
models, but with slight variations in testing tailored to each 
different system.
    Specifically, Cascade asserted that its alternate test procedure 
may be used for rating its CES multiple blower-coils in combination 
with specified condensing units from other manufacturers. In large 
part, the alternate test procedure is essentially the same as the 
current test procedure for central air conditioners and heat pumps in 
10 CFR part 430, Subpart B, Appendix M. However, Cascade's alternate 
test procedure differs from the prescribed test procedure because it 
covers indoor blower coils that have more than one indoor blower and 
motor. Cascade's Petition for Waiver described Cascade's alternate test 
procedure for a particular configuration with two heat pumps and eight 
blowers, and Cascade subsequently supplied methodological rules and 
set-up procedures to describe how its alternate test procedure would be 
used to test other configurations.
    DOE understands that, using the current central air conditioning 
and heat pump test procedure, the company cannot calculate the seasonal 
energy efficiency ratio (SEER) and the heating seasonal performance 
factor (HSPF) for its CES products. Based on the above, DOE believes 
that the identified problems would prevent testing of Cascade's CES 
basic models according to the existing test procedure. However, the 
alternate test procedures described in Cascade's Petition for Waiver 
will enable Cascade to calculate these energy efficiency measures. 
After careful consideration, DOE has decided to adopt the alternate 
test procedure suggested by Cascade to test its CES line of air 
conditioners and heat pumps, including the relevant rules and set-up 
requirements.
Consultations With Other Agencies
    DOE consulted with Federal Trade Commission (FTC) staff and NIST 
concerning the Cascade Petition for Waiver. The FTC staff did not have 
any

[[Page 50789]]

objections to granting a waiver to Cascade. NIST provided a technical 
review of the alternate test procedure.

Conclusion

    After careful consideration of all the materials submitted by 
Cascade, the comment received, the review by National Institute of 
Standards and Technology, and consultation with FTC staff, it is 
ordered that:
    (1) The ``Petition for Waiver'' filed by Cascade Group, LLC 
(Cascade) (Case No. CAC-013) is hereby granted, subject to the 
provisions of paragraphs (2), (3), (4), and (5) of this Order.
    (2) Cascade shall not be required to test or rate its Cascade 
Energy Saver (CES) line of central air conditioners and heat pumps, as 
listed below, on the basis of the test procedures specified in 10 CFR 
part 430, Subpart B, Appendix M, but shall be required to test and rate 
such products according to the alternate test procedure set forth in 
Appendix A (see Cascade's Petition for Waiver, which published in the 
Federal Register on April 20, 2007, 72 FR 19891), as well as the table 
of system configurations in paragraph (3)(B); the rules for 
generalizing the test procedure modifications in paragraph (3)(B); and 
the test procedure set-up requirements in paragraph (4).
    This waiver applies to the following basic models:

(3) Alternate Test Procedure
    (A) Cascade shall be required to test the products listed in 
paragraph (2) according to those test procedures for residential 
central air conditioners and heat pumps prescribed by DOE at 10 CFR 
part 430, Subpart B, Appendix M, except that Cascade shall test such 
products in accordance with the provisions of subparagraph (B) of this 
paragraph. Furthermore, Cascade shall make representations concerning 
its CES multi-blower products covered by this waiver according to the 
provisions of subparagraph (C) below.
    (B) Cascade shall test the CES products covered by this waiver 
under 10 CFR Part 430, Subpart B, Appendix M, as supplemented by the 
following:
(1) Appendix A
    Cascade shall test according to the modifications to the test 
procedure for residential central air conditioners and heat pumps 
contained in Appendix A (which is consistent with the appendix 
submitted as part of Cascade's Petition for Waiver), as supplemented by 
the rules set forth in subparagraph (B)(3) and the set-up requirements 
in subparagraph (B)(4).
(2) Table of System Configurations
    Cascade shall test according to the CES system configurations in 
the following table:

BILLING CODE 6450-01-C

[[Page 50798]]

(3) Rules for Generalizing the Specific Test Procedure Modifications
    Cascade shall test its CES products according to the following 
rules:
    Rule One: These rules apply to testing of residential CES systems 
ranging from two-ton/single-speed/two-blower models up to and including 
dual-2.5-ton heat pump/eight-zone models. It also applies to all CES 
model configurations in between for cooling and heating with single-
phase units that are less than 65,000 btu/hr.
    Rule Two: A 400 cubic feet/minute (cfm) per ton nominal evaporator 
air flow rate will be used, not to exceed 450 cfm per ton on the high 
end (same as 37.5 cfm per 1000 BTU/hr capacity).
    Rule Three: The CES configurations should be tested so that 
regardless of the number of blowers and heat pumps, the resultant test 
procedure will model the CES system as a one-blower evaporator with a 
two-speed fan and one heat pump with one or more speeds. The test 
procedure will follow the procedure found in 10 CFR part 430, Subpart 
B, Appendix M. For example, two heat pumps are to be modeled as a 
single heat pump with two speeds. Also, dual two-speed heat pumps are 
to be modeled as a single heat pump with four speeds. Further, given 
that the number of indoor blowers may range from two to eight per unit, 
these will be modeled as a single blower with two speeds such that half 
the fans will be used to blow air at low speed; when operated at high 
speed, all fans will operate such that the air flow delivered per fan 
equals in total the air flow needed for the total heat pump capacity 
(i.e., 800 cfm for a two-ton heat pump).
    Rule Four: For an even number of blowers, the air flow per blower 
is the same, and the sum of the air flow per blower equals the total 
air flow. For odd number of blowers, see Rule Five.
    Rule Five: If the number of fans is an odd number, divide the 
number of fans by two. Round the quotient up to a whole number, and 
define this whole number as the quantity of ``low-speed fans.'' In the 
case of three blowers, low-speed mode will have two blowers and the 
remaining blower will be used only in high-speed mode. These are 
electrically commutated motors \4\ (ECMs), so adjust the speed of the 
fans that are part of ``low-speed'' mode so that each blower produces 
an equal share of the low-speed air quantity. Likewise, the third 
blower, which operates during high-speed mode, blows an air flow equal 
to half of the total air flow for the tonnage of the heat pump(s). This 
is accomplished by adjustment of the ECM for the single fan, which runs 
in high-speed mode to produce half the total air flow needed for the 
total tonnage.
---------------------------------------------------------------------------

    \4\ An ``electronically commutated motor'' is a high-efficiency, 
programmable, brushless, direct-current (DC) motor utilizing a 
permanent magnet motor and a built-in inverter. DC motors are 
significantly more energy efficient than alternating current (AC) 
motors and much easier to control.
---------------------------------------------------------------------------

    Rule Six: Once the CES system is modeled as required under Rules 
One through Five, perform Tests A, B, C and D (or if the default is 
accepted, then Test D is not required) as found in the procedure of 10 
CFR 430, Subpart B, Appendix M for cooling and heating for the 
variations in speeds and settings found therein.
(4) Test Procedure Set-Up Requirements
    When testing its CES products, Cascade shall adhere to the 
following test procedure set-up requirements:
    (a) Piping: Determine the number of heat pumps. Connect the heat 
pump to the evaporator coil circuit, whether single- or dual-circuit. 
Thus, if there are two heat pumps, there is a heat pump piped into one 
of the circuits of the evaporator coil, while the second heat pump is 
piped into the second circuit of the evaporator coil.
    (b) Unit sizing: If two heat pumps are used, they shall be equal in 
tonnage. Thus, a four-ton Cascade unit will have dual two-ton heat 
pumps attached.
    (c) Fans' cfm sizing: As set forth in Rules Two through Five, 
blowers shall be driven by ECM motors, and the cfm for each blower 
shall be as calculated under Rules Four and Five.
    (d) Ducting the blowers: The discharge of each blower will be 
connected so that the total cfm from all blowers is collected into a 
single duct, sized consistent with appropriate industry pressure-drop 
standards and ducted to the wind tunnel.
    (e) Pressures, delta Ps, temperatures, and other metric points: 
These values are measured by installing devices appropriately 
calibrated to National Institute of Standards and Technology-traceable 
standards for refrigerant and condensate pipes, circuits and air flows 
in the evaporator coil, and condenser coils to measure quantities to be 
used for the calculation of capacities in heating and cooling modes in 
tests A, B, C, and D.
    (C) Representations. In making representations about the energy 
efficiency of its CES multi-blower products, for compliance, marketing, 
or other purposes, Cascade must fairly disclose the results of testing 
under the DOE test procedure, as modified by the alternate test 
procedure in this waiver.
    (4) This waiver shall remain in effect from the date of issuance of 
this Decision and Order until the effective date of a DOE final rule 
prescribing amended test procedures appropriate to the above model 
series manufactured by Cascade.
    (5) This waiver is conditioned upon the presumed validity of 
statements, representations, and documentary materials provided by the 
petitioner. This waiver may be revoked or modified at any time upon a 
determination that the factual basis underlying the Petition for Waiver 
is incorrect, or DOE determines that the results from the alternate 
test procedure are unrepresentative of the basic model's true energy 
consumption characteristics.
