Energy Conservation Program for Consumer Products: Test

Procedures for Clothes Dryers and Room Air Conditioners

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

Energy.

ACTION: Notice of proposed rulemaking and notice of public meeting.

SUMMARY: In order to implement recent amendments to the Energy Policy and Conservation Act (EPCA), the U.S. Department of Energy (DOE) proposes to amend its test procedures for residential clothes dryers and room air conditioners to provide for measurement of standby mode and off mode power use by these products. The amendments would incorporate into the DOE test procedures relevant provisions from the

International Electrotechnical Commission's (IEC) Standard 62301,

``Household electrical appliances--Measurement of standby power''

(First Edition 2005-06), as well as language to clarify application of these provisions specifically for measuring standby mode and off mode power consumption in clothes dryers and room air conditioners. DOE will hold a public meeting to discuss and receive comments on the issues presented in this notice.

DATES: DOE will accept comments, data, and information regarding the notice of

Page 74640

proposed rulemaking (NOPR) before and after the public meeting, but no later than February 23, 2009. See section V, ``Public Participation,'' of this NOPR for details.

I. Background and Authority

Title III of the Energy Policy and Conservation Act (42 U.S.C. 6291, et seq.; ``EPCA'' or, in context, ``the Act'') sets forth a variety of provisions designed to improve energy efficiency. Part A of

Title III (42 U.S.C. 6291-6309) establishes the ``Energy Conservation

Program for Consumer Products Other Than Automobiles,'' including clothes dryers and room air conditioners (all of which are referred to below as ``covered products'').\1\ (42 U.S.C. 6291(1)-(2) and 6292(a)(2) and (8))

\1\ All references to EPCA refer to the statute as amended including through the Energy Independence and Security Act of 2007,

Public Law 110-140.

Under the Act, this program consists essentially of three parts:

(1) Testing; (2) labeling; and (3) Federal energy conservation standards. The testing requirements consist of test procedures that, pursuant to EPCA, manufacturers

Page 74641

of covered products must use as the basis for certifying to DOE that their products comply with applicable energy conservation standards adopted under EPCA and for representations about the efficiency of those products. Similarly, DOE must use these test requirements to determine whether the products comply with EPCA standards. Under 42

U.S.C. 6293, EPCA sets forth criteria and procedures for DOE's adoption and amendment of such test procedures. EPCA provides that ``[a]ny test procedures prescribed or amended under this section shall 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, as determined by the Secretary [of Energy], and shall not be unduly burdensome to conduct.'' (42 U.S.C. 6293(b)(3)) 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 thereon, with a comment period no less than 60 days and not to exceed 270 days. (42 U.S.C. 6293(b)(2))

Finally, in any rulemaking to amend 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))

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))

DOE's test procedures for clothes dryers are found at 10 CFR part 430, subpart B, appendix D. DOE established its test procedure for clothes dryers in a final rule published in the Federal Register on May 19, 1981. 46 FR 27324. The test procedure includes provisions for determining the energy factor (EF) for clothes dryers, which is a measure of the total energy required to dry a standard test load of laundry to a ``bone dry'' \2\ state.

\2\ ``Bone dry'' is defined in the DOE clothes dryer test procedure as ``a condition of a load of test clothes which has been dried in a dryer at maximum temperature for a minimum of 10 minutes, removed and weighed before cool down, and then dried again for 10- minute periods until the final weight change of the load is 1 percent or less.'' (10 CFR subpart B, appendix D, section 1.2)

DOE's test procedures for room air conditioners are found at 10 CFR part 430, subpart B, appendix F. DOE established its room air conditioner test procedure on June 1, 1977, and redesignated and amended it on June 29, 1979. 42 FR 27898; 44 FR 37938. The existing room air conditioner test procedure incorporates by reference two industry test standards: (1) American National Standard (ANS) (since renamed American National Standards Institute (ANSI)) Z234.1-1972,

``Room Air Conditioners;'' \3\ and (2) American Society of Heating,

Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 16-69,

``Method of Testing for Rating Room Air Conditioners.'' \4\ The DOE test procedure includes provisions for determining the energy efficiency ratio (EER) of room air conditioners, which is the ratio of the cooling capacity in British thermal units (Btu) to the power input in watts (W).

\3\ ANSI standards are available for purchase at http:// www.ansi.org.

\4\ ASHRAE standards are available for purchase at http:// www.ashrae.org.

As currently drafted, the test procedures for the products at issue in this rulemaking generally do not account for standby mode and off mode energy consumption, except in one narrow product class.

Specifically, for gas dryers with continuously burning pilot lights,

DOE's current test procedure for clothes dryers addresses the standby energy use of such pilot lights, but otherwise, neither this test procedure nor DOE's test procedure for room air conditioners addresses energy use in the standby or off modes.

The Energy Independence and Security Act of 2007 \5\ (EISA 2007) amended EPCA, and in relevant part, directs DOE to amend its test procedures to include measures of standby mode and off mode energy consumption. The EISA 2007 amendments to EPCA further direct DOE to amend the test procedures to integrate such energy consumption into a single energy descriptor for that product. If that is technically infeasible, DOE must prescribe a separate standby mode and off mode energy use test procedure, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)) Any such amendment must consider the most current versions of the International Electrotechnical Commission (IEC)

Standard 62301 and IEC Standard 62087 [``Methods of measurement for the power consumption of audio, video, and related equipment'' (Second

Edition, 2008-09)].\6\ Id. For clothes dryers and room air conditioners, DOE must prescribe any such amendment to the test procedures by March 31, 2009. (42 U.S.C. 6295(gg)(2)(B)(ii))

\5\ Public Law 110-140 (enacted Dec. 19, 2007).

\6\ IEC standards are available for purchase at: http:// www.iec.ch.

On October 9, 2007, DOE published a notice in the Federal Register announcing the availability of a framework document to initiate rulemaking to consider amended energy conservation standards for residential clothes dryers and room air conditioners (hereafter the

October 2007 Framework Document). 72 FR 57254. The issuance of a framework document is the first step in conducting an appliance standards rulemaking. In the October 2007 Framework Document, DOE identified specific ways in which it could revise its test procedures for these two products and requested stakeholder comment on whether it should adopt such revisions. Specifically, DOE sought comment on potential amendments to the clothes dryer test procedure to: (1)

Reflect lower remaining moisture content in clothes loads; (2) account for fewer use cycles; and (3) add the capability to test vent-less clothes dryers. (Framework Document, No. 1 at pp. 4-6) \7\ For room air conditioners, DOE requested input on potential amendments to the test procedure to: (1) Incorporate the most recent ANSI and ASHRAE test standards; (2) reduce the annual operating hours; and (3) measure part- load performance. (Framework Document, No. 1 at pp. 6-7)

\7\ A notation in this form provides a reference for information that is in the docket of DOE's rulemaking to develop standards for clothes dryers and room air conditioners (Docket No. EERE-2007-BT-

STD-0010), which is maintained in the Resource Room of the Building

Technologies Program. This notation indicates that the statement preceding the reference was made in DOE's Framework Document, which is document number 1 in the docket, and appears at pages 4-6 of that document.

Because the October 2007 Framework Document was issued before the enactment of EISA 2007, these potential revisions did not address standby mode or off mode energy use. DOE is continuing to consider all such potential revisions, but in this rulemaking, DOE's proposal is limited to amending its test procedures for clothes dryers and room air conditioners to include methods for measuring standby mode and off mode power consumption, thereby allowing the agency to meet the EISA 2007 deadline of March 31, 2009 for adopting such amendments. DOE plans to publish a separate Federal Register notice to address the balance of the test procedure issues, including those on which it requested comment in the October 2007 Framework Document.

Both test procedure rulemakings are anticipated to support a concurrent energy conservation standards rulemaking for residential clothes dryers

Page 74642

and room air conditioners. For clothes dryers, the National Appliance

Energy Conservation Act of 1987 (NAECA), Public Law 100-12, amended

EPCA to establish prescriptive standards for clothes dryers, requiring that gas dryers manufactured on or after January 1, 1988 not be equipped with a constant burning pilot and further requiring that DOE conduct two cycles of rulemakings to determine if more stringent standards are justified. (42 U.S.C. 6295(g)(3) and (4)) On May 14, 1991, DOE published a final rule in the Federal Register establishing the first set of performance standards for residential clothes dryers

(56 FR 22250); the new standards became effective on May 14, 1994. 10

CFR 430.32(h). DOE initiated a second standards rulemaking for residential clothes dryers by publishing an advance notice of proposed rulemaking (ANOPR) in the Federal Register on November 14, 1994. 59 FR 56423. However, pursuant to the priority-setting process outlined in

DOE's ``Procedures for Consideration of New or Revised Energy

Conservation Standards for Consumer Products'' (the ``Process

Rule''),\8\ DOE classified the clothes dryer standards rulemaking as a low priority for its fiscal year 1998 priority-setting process. As a result, DOE suspended the standards rulemaking activities for them. DOE has since resumed the rulemaking activities, and has recently initiated the second cycle of clothes dryer standards rulemakings. 72 FR 57254

(October 9, 2007).

\8\ 61 FR 36974 (July 15, 1996) (establishing 10 CFR part 430, subpart C, appendix A).

NAECA established performance standards for room air conditioners that became effective on January 1, 1990, and directed DOE to conduct two cycles of rulemakings to determine if more stringent standards are justified. (42 U.S.C. 6295(c)(1) and (2)) On March 4, 1994, DOE published a NOPR for several products, including room air conditioners. 59 FR 10464. As a result of the Process Rule, DOE suspended activities to finalize standards for room air conditioners. DOE subsequently resumed rulemaking activities related to room air conditioners, and on

September 24, 1997, DOE published a final rule establishing an updated set of performance standards, with an effective date of October 1, 2000. 62 FR 50122; 10 CFR 40.32(b). Concurrent with the clothes dryer rulemaking, DOE has recently initiated the second cycle of room air conditioner standards rulemakings. 72 FR 57254.

EISA 2007 includes amendments to EPCA that direct DOE to incorporate standby and off mode energy use into any final rule establishing or revising a standard for a covered product adopted after

July 1, 2010. (42 U.S.C. 6295(gg)(3)) DOE anticipates publishing the next final rule revising efficiency standards for clothes dryers and room air conditioners by June 30, 2011. Because publication of the final rule revising efficiency standards will fall after July 1, 2010

(the date after which any final rule establishing or revising a standard must incorporate standby and off mode energy use), this final rule must incorporate standby and off mode energy use, thereby necessitating the adoption of relevant standby and off mode provisions into the test procedures for these products.

II. Summary of the Proposal

In today's NOPR, DOE proposes to amend the test procedures for clothes dryers and room air conditioners in order to: (1) Provide a foundation for DOE to develop and implement energy conservation standards that address the energy use of these products when in standby mode and off mode; and (2) address the statutory requirement to expand test procedures to incorporate measures of standby mode and off mode power consumption. The following paragraphs summarize these proposed changes.

In amending the current test procedures, DOE proposes to incorporate by reference into both the clothes dryer and room air conditioner test procedures specific clauses from IEC Standard 62301,

``Household electrical appliances--measurement of standby power''

(First Edition, 2005-06) regarding test conditions and test procedures for measuring standby mode and off mode power consumption. DOE also proposes to incorporate into each test procedure the definitions of

``active mode,'' ``standby mode,'' and ``off mode'' that are set forth in section 325(gg)(1)(A) of EPCA. (42 U.S.C. 6295(gg)(1)(A)) Further,

DOE proposes to include in each test procedure additional language that would clarify the application of clauses from IEC Standard 62301 for measuring standby mode and off mode power consumption.\9\

\9\ EISA 2007 directs DOE to also consider IEC Standard 62087 when amending its test procedure to include standby mode and off mode energy consumption. See 42 U.S.C. 6295(gg)(2)(A). However, IEC

Standard 62087 addresses the methods of measuring the power consumption of audio, video, and related equipment. As explained subsequently in this notice, the narrow scope of this particular IEC

Standard reduces its relevance to today's proposal.

For clothes dryers, DOE is proposing definitions for different standby modes--a general ``inactive'' mode, a ``cycle finished'' mode, and a ``delay start'' mode--each of which would be separately tested under the procedure, along with energy use in the off mode.

Furthermore, DOE proposes to clarify testing in the delay start mode by requiring that the delay time be set at 5 hours and that the test be conducted for 60 minutes, after waiting at least 5 minutes for power input to stabilize. Finally, DOE proposes to establish new methods to calculate clothes dryer energy use and energy efficiency that include the energy used in the standby modes and the off mode.

For room air conditioners, DOE proposes definitions for different standby modes--a general ``inactive'' mode, a ``delay start'' mode, and an ``off-cycle'' mode--each of which would be separately tested under the procedure, along with energy use in the off mode. DOE also proposes to specify the test duration for cases in which the measured power is unstable (i.e., varies more than 5 percent during a 5-minute period), and proposes that standby mode and off mode testing be conducted with roomside air temperature at 74 2 degrees Fahrenheit

([deg]F) to reflect typical operating conditions for room air conditioners. In addition, DOE proposes to specify that, during standby mode and off mode testing for which setting the thermostat or temperature setpoint \10\ is applicable, the setpoint for the room air conditioner is to be set at 79 [deg]F, in order to provide uniform testing conditions. Finally, DOE proposes to establish new methods to calculate energy use and energy efficiency, which include energy use in the standby modes and the off mode.

\10\ The term ``setpoint'' refers to the desired value in a closed-loop feedback system and is typically used in the context of regulating temperature or pressure.

Under 42 U.S.C. 6295(gg)(2)(C), EPCA provides that amendments to the test procedures to include standby mode and off mode energy consumption will not determine compliance with previously established standards. (U.S.C. 6295(gg)(2)(C)) Because the proposed amended test procedures would not alter existing measures of energy consumption or efficiency, today's notice would not affect a manufacturer's ability to demonstrate compliance with previously established standards. These amended test procedures would become effective, in terms of adoption into the CFR, 30 days after the date of publication in the Federal

DOE's amended test procedure regulations codified in the CFR would

Page 74643

clarify that the procedures and calculations for standby mode and off mode energy consumption need not be performed to determine compliance with the current energy conservation standards for clothes dryers and room air conditioners, because the current energy conservation standards do not account for standby and off mode power consumption.

Instead, manufacturers would be required to use the test procedures' standby and off mode provisions to demonstrate compliance with DOE's energy conservation standards on the effective date of a final rule establishing amended energy conservation standards for these products that address standby and off mode power consumption.

III. Discussion

A. Products Covered by the Test Procedure Changes

Today's proposed amendments to DOE's clothes dryer test procedure cover both electric and gas clothes dryers, which DOE's regulations define as:

Electric clothes dryer means a cabinet-like appliance designed to dry fabrics in a tumble-type drum with forced air circulation. The heat source is electricity and the drum and blower(s) are driven by an electric motor(s).

Gas clothes dryers means a cabinet-like appliance designed to dry fabrics in a tumble-type drum with forced air circulation. The heat source is gas and the drum and blower(s) are driven by an electric motor(s). 10 CFR 430.2

These definitions and the proposed amendments thereto cover both vented and vent-less clothes dryers, as well as combination washer/ dryers.

Today's proposed amendments to DOE's room air conditioner test procedure cover products that meet the following definition from DOE's regulations:

Room air conditioner means a consumer product, other than a

``packaged terminal air conditioner,'' which is powered by a single phase electric current and which is an encased assembly designed as a unit for mounting in a window or through the wall for the purpose of providing delivery of conditioned air to an enclosed space. It includes a prime source of refrigeration and may include a means for ventilating and heating. 10 CFR 430.2

This definition and the proposed amendments thereto cover room air conditioners designed for single- or double-hung windows with or without louvered sides and with or without reverse cycle, as well as casement-slider and casement-only window-type room air conditioners.

B. Effective Date for the Amended Test Procedures

As indicated above, EPCA requires DOE to amend the test procedures for clothes dryers and room air conditioners to incorporate measurement of standby mode and off mode energy use in a final rule issued no later than March 31, 2009. Such action is necessary to permit manufacturers to certify that equipment complies with any newly established energy conservation standards that take into account standby and off mode energy use. When DOE is developing energy conservation standards and determines that test procedure amendments are required, DOE strives to issue a final rule amending the test procedure before issuing a proposed rule for energy conservation standards. The effective date of the modified clothes dryer and room air conditioner test procedures would be 30 days after the date of publication in the Federal Register of a final rule in this test procedures rulemaking. However, DOE's amended test procedure regulations codified in the CFR would clarify that the procedures and calculations for standby mode and off mode energy consumption need not be performed to determine compliance with the current energy conservation standards for clothes dryers and room air conditioners, because the current energy conservation standards do not account for standby and off mode power consumption.\11\ The proposed notes regarding the applicability of the test procedure provisions on standby mode and off mode energy use in Appendix D

(clothes dryers) and Appendix F (room air conditioners) will be removed in subsequent notices of final rulemaking that amend the energy conservation standards for these products.

\11\ Pursuant to a court consent decree, DOE must complete a standards rulemaking for residential clothes dryers and room air conditioners by June 30, 2011. As part of the rulemaking considering amended energy conservation standards for these products, DOE will also address the issue of standby and off mode power consumption. If adopted, such standards would be effective in June 2014, at which time the standby and off mode provisions of the test procedures would become mandatory for determining compliance with the amended energy conservation standards.

C. Incorporating by Reference IEC Standard 62301 (First Edition, 2005- 06) for Measuring Standby Mode and Off Mode Power in Clothes Dryers and

Room Air Conditioners

Per EPCA, DOE considered the most current versions of IEC Standard 62301 and IEC Standard 62087 for measuring power consumption in standby mode and off mode. (42 U.S.C. 6295(gg)(2)(A)) DOE noted that IEC

Standard 62301 provides for measuring standby power in electrical appliances, including clothes dryers and room air conditioners, and, thus, is applicable to the proposed amendments to the clothes dryer and room air conditioner test procedures. DOE also reviewed IEC Standard 62087, which specifies methods of measuring the power consumption of TV receivers, video cassette recorders (VCRs), set top boxes, audio equipment, and multi-function equipment for consumer use. IEC Standard 62087 does not, however, include measurement for the power consumption of electrical appliances such as clothes dryers and room air conditioners. Therefore, DOE determined that IEC Standard 62087 was unsuitable for the proposed amendments to the clothes dryer and room air conditioner test procedures.

DOE proposes to incorporate by reference into the DOE test procedures for clothes dryers and room air conditioners specific clauses from IEC Standard 62301 for measuring standby mode and off mode power. Specifically, these clauses provide test conditions and test procedures for measuring the average standby mode and average off mode power consumption. Regarding testing conditions, section 4 of IEC

Standard 62301 provides conditions for the supply voltage, frequency, and voltage waveform, and power measurement meter tolerances to provide for repeatable and precise measurements of standby mode and off mode power consumption. Section 5 of IEC Standard 62301 regarding test procedures provides a method for measuring power consumption when the power measurement is stable, as well as a method of measuring when the power measurement is unstable.

Other provisions of IEC Standard 62301 are not applicable to measuring standby mode and off mode power testing of clothes dryers and room air conditioners. Hence, not all provisions of IEC Standard 62301 are incorporated by reference into the DOE test procedures. For example, IEC Standard 62301 provides general conditions for power supply voltage and frequency, which the current DOE test procedure

Page 74644

for clothes dryers already addresses. IEC Standard 62301 also provides requirements for information to be recorded in a test report, which are beyond the scope of DOE's test procedure. Consequently, only the applicable sections and clauses (as stated above) are incorporated by reference in today's proposed rule.

Specifically, DOE proposes to incorporate by reference in the DOE test procedure for clothes dryers the following sections from IEC

Standard 62301: From section 4 (``General conditions for measurements''), paragraph 4.2, ``Test room,'' paragraph 4.4, ``Supply voltage waveform,'' and paragraph 4.5, ``Power measurement accuracy;'' and section 5 (``Measurements''), paragraph 5.1, ``General'' and paragraph 5.3, ``Procedure.'' DOE proposes to reference these same provisions in the DOE test procedure for room air conditioners, as well as section 4, paragraph 4.3, ``Power supply.''

The EPCA requirement to consider IEC Standard 62301 in developing modified test procedures for clothes dryers and room air conditioners presents a potential conflict in defining ``standby mode.'' EPCA defines ``standby mode'' as the condition in which a product is connected to a main power source and offers one or more of the following user-oriented or protective functions: (1) To facilitate the activation or deactivation of other functions (including active mode) by remote switch (including remote control), internal sensor, or timer; and/or (2) to provide continuous functions, including information or status displays (including clocks) or sensor-based functions. (42

U.S.C. 6295(gg)(1)(A)(iii)). In contrast, paragraph 3.1 of the current version of IEC Standard 62301 defines ``standby mode'' as the ``lowest power consumption mode which cannot be switched off (influenced) by the user and that may persist for an indefinite time when an appliance is connected to the main electricity supply and used in accordance with the manufacturer's instructions.'' In addition, prior to EISA 2007, DOE adopted a definition for ``standby mode'' nearly identical to that of

IEC Standard 62301 in the dishwasher test procedure, in which ``standby mode'' ``means the lowest power consumption mode which cannot be switched off or influenced by the user and that may persist for an indefinite time when an appliance is connected to the main electricity supply and used in accordance with the manufacturer's instructions.''

(10 CFR part 430, subpart B, appendix C, section 1.14). DOE welcomes comment on the appropriate approach for resolving these inconsistencies between EPCA, the IEC Standard 62301 which EPCA references, and the precedent set by the dishwasher test procedure. While EPCA specifies that DOE may consider the definition for ``standby mode'' provided in the most current version of IEC Standard 62301 in updating its test procedure, DOE proposes to adopt the broader, statutory definition of

``standby mode'' provided in EPCA for reasons of greater specificity and clarity, and to include that definition in the test procedures for clothes dryers and room air conditioners.

Further, the agency notes that, while section 325(gg)(2)(A) of EPCA

(42 U.S.C. 6295(gg)(2)(A)) requires that the amended test procedures consider the most current version of IEC Standard 62301, the IEC is developing an updated version of this standard, IEC Standard 62301

(Second Edition). This updated version of IEC Standard 62301 is expected to include definitions of ``off mode,'' ``network-connected standby mode,'' and ``disconnected mode,'' and would also revise the current IEC Standard 62301 definition of ``standby mode.'' However, because the IEC anticipates that this new version of Standard 62301 will likely be published in July 2009, this later version of the standard will be unavailable in time for DOE to consider it and to still meet the EISA 2007 deadline for issuance of a final rule amending the relevant test procedure to include measures of standby mode and off mode energy consumption by March 31, 2009. See 42 U.S.C. 6295(gg)(2)(B)(ii). Hence, the First Edition 2005-06 of IEC Standard 62301 will be the ``current version'' at the time of publication of the final rule, so consideration thereof will comply with EPCA.

Accordingly, DOE plans to use the First Edition 2005-06 of IEC Standard 62301 in today's proposed test procedure. After the final rule is published, amendments to the referenced standards would be adopted by

DOE only if the agency later incorporates them into its procedures.

In reviewing alternative standby power test procedures for potential amendments to the DOE test procedure, DOE also investigated both testing conditions and testing methods specified in the test procedures used by countries that are considered to be international leaders in reducing standby power consumption. These countries include

Japan, Korea, and Australia, all of which use procedures similar to those of IEC Standard 62301, and/or reference that standard.

D. Determination of Modes To Be Incorporated

As noted above, DOE proposes to incorporate into the clothes dryer and room air conditioner test procedure the definitions of ``active mode,'' ``standby mode,'' and ``off mode'' specified by EPCA. EPCA defines ``active mode'' as ``the condition in which an energy-using product--

(I) Is connected to a main power source;

(II) Has been activated; and

(III) Provides 1 or more main functions.''

(42 U.S.C. 6295(gg)(1)(A)(i))

EPCA defines ``standby mode'' as ``the condition in which an energy-using product--

(I) Is connected to a main power source; and

(II) Offers 1 or more of the following user-oriented or protective functions:

(aa) To facilitate the activation or deactivation of other functions (including active mode) by remote switch (including remote control), internal sensor, or timer.

(bb) Continuous functions, including information or status displays

(including clocks) or sensor-based functions.''

(42 U.S.C. 6295(gg)(1)(A)(iii)) This definition differs from the one provided in IEC Standard 62301 by permitting the inclusion of multiple standby modes.

EPCA defines ``off mode'' as ``the condition in which an energy- using product --

(I) Is connected to a main power source; and

(II) Is not providing any standby mode or active mode function.''

\12\

\12\ DOE notes that some features that provide consumer utility, such as displays and remote controls, are associated with standby mode and not off mode. A clothes dryer or room air conditioner is considered to be in ``off mode'' if it is plugged in to a main power source, is not being used for an active function such as drying clothing or providing cooling, and is consuming power for features other than a display, controls (including a remote control), or sensors required to reactivate it from a low power state. For example, a clothes dryer with mechanical controls and no display or continuously-energized moisture sensor, but that consumed power for components such as a power supply when the unit was not activated, would be considered to be in off mode when not providing an active function. For room air conditioners, a unit with mechanical controls and no display or remote control but with a power supply which is consuming energy, for example, could be considered to be in off mode while not providing an active function.

(42 U.S.C. 6295(gg)(1)(A)(ii))

DOE recognizes that these definitions for ``active mode,''

``standby mode,'' and ``off mode'' were developed to be broadly applicable for many energy-using products. For specific products

Page 74645

with multiple functions, these broad definitions could lead to unintended consequences if the meaning of ``main functions'' is narrowly interpreted, as illustrated by the following example:

A ``room air conditioner,'' as defined in section III.A, provides delivery of conditioned air to an enclosed space. This product includes a prime source of refrigeration and may include a means for ventilating and heating. A narrow interpretation of this definition would be that the main function of providing delivery of conditioned air is strictly a cooling function. Such an interpretation would imply that delivery of cooled air is the only active mode under the EPCA definition, as amended by EISA 2007. Under such an interpretation, operation of the room air conditioner fan without operation of the compressor would likely be considered an off mode, since it does not strictly fit the definition of standby mode and because off mode includes all modes which are not standby mode or active mode.

To address this potential problem, DOE proposes to amend to the clothes dryer and room air conditioner test procedures to clarify the range of main functions that would be classified as active mode functions. DOE further proposes to amend the clothes dryer and room air conditioner test procedures to define multiple standby modes that would be separately tested under the procedures. DOE welcomes comment on the above approach. 1. Clothes Dryer Mode Definitions

DOE proposes the following mode definitions for clothes dryers:

``Active mode'' means a mode in which the clothes dryer is performing the main function of tumbling the clothing with or without heated or unheated forced air circulation to remove moisture from the clothing and/or remove or prevent wrinkling of the clothing;

``Inactive mode'' means a standby mode other than delay start mode or cycle finished mode that facilitates the activation of active mode by remote switch (including remote control), internal sensor, or timer, or provides continuous status display;

``Cycle finished mode'' means a standby mode that provides continuous status display following operation in active mode;

``Delay start mode'' means a standby mode that facilitates the activation of active mode by timer; and

``Off mode'' means a mode in which the clothes dryer is not performing any active or standby function. 2. Room Air Conditioner Mode Definitions

For room air conditioners, DOE proposes the following mode definitions:

``Active mode'' means a mode in which the room air conditioner is performing the main function of cooling or heating the conditioned space, or circulating air through activation of its fan or blower, with or without energizing active air-cleaning components or devices such as ultraviolet (UV) radiation, electrostatic filters, ozone generators, or other air-cleaning devices;

``Inactive mode'' means a standby mode other than delay start mode or off-cycle mode that facilitates the activation of active mode by remote switch (including remote control) or internal sensor or provides continuous status display;

``Delay start mode'' means a standby mode in which activation of an active mode is facilitated by a timer;

``Off-cycle mode'' means a standby mode in which the room air conditioner: (1) Has cycled off its main function by thermostat or temperature sensor; (2) does not have its fan or blower operating; and

(3) will reactivate the main function according to the thermostat or temperature sensor signal;

``Off mode'' means a mode in which a room air conditioner is not performing any active or standby function.

Off-cycle mode could be considered part of an active mode in which a room air conditioner is cycling its compressor on and off to maintain an average room temperature. However, since the current test procedure treats the cooling mode as occuring only when the compressor is operating, DOE proposes the off-cycle mode to account for the time when the space is being conditioned and the compressor and fan are not operating.

E. Adding Specifications for the Test Methods and Measurements for

Clothes Dryer and Room Air Conditioner Standby Mode and Off Mode

Testing

DOE is proposing test procedures for measuring all standby and off modes associated with clothes dryers and room air conditioners. This section discusses product-specific clarifications of the procedures of

IEC Standard 62301 when used to measure standby and off mode energy use for clothes dryers and room air conditioners. 1. Clothes Dryers

DOE understands that displays on clothes dryers may reduce power consumption by dimming after a certain period of user inactivity. For those clothes dryers for which the power input in inactive mode varies in this fashion during testing, DOE proposes that the test be conducted after the power level has dropped to its low level.

DOE understands that clothes dryers with a delay start capability may use varying amounts of power during delay start mode depending on the delay time, the time displayed, and/or display indication of mode status. Paragraph 5.3.1 of section 5.3 ``Procedure'' of IEC Standard 62301 instructs a test technician to ``[c]onnect the product to be tested to the metering equipment, and select the mode to be measured.

After the product has been allowed to stabilize for at least 5 min., monitor the power consumption for not less than an additional 5 min.''

The lack of specificity in this language regarding the test period could allow a manufacturer to measure standby power consumption by selecting delay start times with relatively low power consumption, producing test results that would neither be comparable to those obtained using other time periods nor represent the true standby power consumption of its clothes dryers. Consequently, to ensure comparable and valid results, DOE proposes to include in the clothes dryer test procedure a specification for the delay start time to be set at 5 hours, and for power to be monitored for 60 minutes after waiting at least 5 minutes for power input to stabilize.

In determining the specifications for delay start parameters, DOE considered the possibility that display power input would depend on the time displayed, which is typically the time in hours remaining before the start. Displays may be one or two digits. Some two-digit displays may show whole numbers for remaining delay hours of 10 or more and both the ones and tenths digits for remaining delay hours of 9.9 or less. By analyzing the number of light emitting diodes (LEDs) activated in LED displays of the remaining hours over a range of delay times, DOE concluded that the average number of LEDs lit for the range of all possible delay times would be best approximated by the average LEDs lit for either single-digit or two-digit displays in a 60-minute test if the delay time is set at 5 hours. DOE also is aware that some clothes dryers with the delay start feature do not allow delay time greater than 5 hours.

DOE proposes to adopt the test room ambient temperature specified by IEC Standard 62301 for standby mode and off mode testing. Under these conditions, the test room ambient temperature would be 73.4 9 [deg]F, which is slightly different from the

Page 74646

ambient temperature currently specified for DOE's drying performance tests of clothes dryers (75 3 [deg]F). Today's proposal, however, permits manufacturers who opt to test simultaneously for all three conditions to do so using the current ambient temperature requirements for drying tests, since these are within the limits specified by IEC Standard 62301. Alternatively, the proposed temperature specifications would allow a manufacturer that opts to conduct standby mode and off mode testing separately from drying tests more latitude in maintaining ambient conditions. DOE requests comment on the appropriateness of this proposed modified test room ambient temperature range. 2. Room Air Conditioners

A given unit or model of a room air conditioner with a temperature, clock, or timer display may use varying amounts of standby power depending on the numbers being displayed. During preliminary testing conducted by DOE for room air conditioners (``RAC Standby Testing''), for a two-digit display capable of displaying temperature or delay start time, standby power use for different digit combinations was observed to vary by as much as 22 percent. (RAC Standby Testing, No. 1 at p.1) Paragraph 5.3.1 of section 5.3 ``Procedure'' of IEC Standard 62301 instructs a test technician to ``[c]onnect the product to be tested to the metering equipment, and select the mode to be measured.

After the product has been allowed to stabilize for at least 5 min., monitor the power consumption for not less than an additional 5 min.''

As with clothes dryers, the lack of specificity in this IEC Standard 62301 language regarding the test period or control setting could allow a manufacturer to measure standby power consumption by selecting temperatures or time periods with relatively low power consumption, thereby producing test results that would not be comparable to those obtained using other temperatures or time periods and that would not represent the true standby power consumption of its room air conditioners. In addition, different manufacturers could take different approaches in selecting cycles for testing.

Another concern arises when a room air conditioner has a delay start mode. To ensure comparable and valid results, DOE proposes to include in this test procedure a separate test in the delay start mode, in which the unit is set to a delay start time of 5 hours and the power is monitored for 60 minutes after allowing the power input level to stabilize for at least 5 minutes. The rationale for specifying the 5- hour delay start time and the 60-minute measurement time is the same as that presented above regarding selection of parameters for clothes dryer testing in delay start mode (i.e., the average power consumption of a display for these conditions would be most representative of average power consumption under the entire range of possible delay hours).

DOE recognizes that different room air conditioners provide different temperature displays when operating. Some room air conditioners display actual room temperature, while others display setpoint temperature. DOE proposes to address the possibility of these different approaches by requiring that the test room temperature be maintained at 74 2 [deg]F and that the room setpoint temperature be set at 79 [deg]F. DOE selected this test room temperature, which is lower than the room air temperature which is specified for the existing DOE cooling performance tests (80 0.5 [deg]F), because DOE has tentatively concluded that the display energy consumption associated with the proposed room temperature range would be the most representative of an average display energy consumption over all reasonable room temperature conditions. DOE considered that a different number of LEDs may be energized in an LED display, depending on actual room or setpoint temperature. For the specified room temperature range and setpoint, the average power consumption for the possible combinations of LEDs energized would be close to the average power consumption for the full range of reasonable actual room and setpoint temperatures displayed

(i.e., 70 [deg]F to 85 [deg]F). Hence, the chosen room ambient and setpoint temperatures would ensure that: (1) The power consumption of any display, whether indicating actual or setpoint temperature, represents an average power consumption associated with the range of typical user room temperatures and setpoints; and (2) the room air conditioner will not cycle the compressor on, since the setpoint will be higher than actual room ambient temperature. DOE also notes that, although the 80 0.5 [deg]F room air temperature specified by the current test procedure falls within the allowable range specified in IEC Standard 62301 (73.4 9 [deg]F), the proposed test room temperature would be more representative of conditions in which a room air conditioner would likely be in standby mode, since it is reasonable to assume the unit would be in active mode if the room air temperature were near 80 [deg]F. DOE requests comment on the appropriateness of this proposed modified test room ambient temperature range.

DOE believes that IEC Standard 62301 is otherwise suitable to address possible variation in the power levels associated with the off and standby modes, requiring only appropriate lengthening of the sample period, averaging of the power input, and measurement of a number of complete cycles, if necessary, to capture cyclic power input.

F. Calculation of Energy Use Associated With Standby Modes and Off Mode

Measurements of energy consumption associated with each standby and off mode for clothes dryers and room air conditioners are expressed in

W. The total energy impact of the power expended in these modes depends on both the power level in W of each mode and the time spent in each mode. This section discusses the approach proposed for clothes dryers and room air conditioners for calculating energy use associated with standby modes and off mode and the numbers of hours proposed to be associated with each mode. 1. Clothes Dryers

Energy use for clothes dryers is expressed in terms of total energy use per drying cycle; measurements of standby and off mode energy use will be expressed in this fashion as well, in order to maintain consistency. Energy used during a drying cycle is directly measured as energy use per cycle in the test procedure, although adjustments are made to the directly measured energy to account for differences between test and field conditions. The energy use associated with continuously burning pilot lights of gas dryers is measured and is converted to an energy use per cycle by dividing calculated annual gas energy use by the representative average number of drying cycles per year (i.e., 416). 10 CFR part 430, subpart B, appendix D, section 4.4. This procedure for gas pilot lights provides an approach for calculating standby power consumption.

In the existing test procedure, energy use per cycle for continuously burning pilot lights is calculated by multiplying the energy use measured for a period of one hour by an established number of hours per year that the dryer is not in drying mode, and dividing by the representative average cycles per year. The existing test procedure established that a gas clothes dryer is in the drying mode 140 hours per year, and that the

Page 74647

balance of the year (8,620 hours) is the established number of hours associated with the pilot light energy consumption.

DOE proposes to adopt a similar approach for measuring energy consumption during standby and off modes for clothes dryers.

Specifically, DOE proposes to adopt the current 140 hours associated with drying (i.e., the active mode) and to associate the remaining 8,620 hours of the year with the standby and off modes. DOE is proposing this approach because it believes that the number of drying hours established in the existing test procedure for gas dryers is a reasonable representation of the active mode hours for all dryers, and because, to date, DOE has not identified any other reliable data regarding average dryer cycle times. DOE welcomes information and data on such average cycle times, as well as annual dryer usage.

In order to establish the number of hours per year in each standby and off mode, as defined in section III.D.1, DOE investigated studies of dryer usage patterns and found only one study of the time spent by clothes dryers in different standby modes.\13\ This publication presents results of a household survey conducted in 2000, which measured standby modes for 35 clothes dryers with an average age of 11 years. The daily time spent in each mode in this study averaged one quarter hour for ``drying,'' zero hours for ``delay start'' and

``active standby'' modes, and the remaining hours split 5 percent for

``end of program'' mode and 95 percent for off mode. The ``active standby mode'' of the study is equivalent to the ``inactive mode'' defined in section III.D.1 of this notice, and the ``end of program mode'' is equivalent to the ``cycle finished mode'' in section III.D.1.

DOE has tentatively concluded from these results that clothes dryers spend little time in cycle finished mode and probably spend little time in delay start mode. The average age of the clothes dryers in the study suggests that most of these dryers had electromechanical rather than electronic controls (prevalent among dryers currently on the market), indicating that the dryers in the study would not likely have had inactive mode or delay start mode. Hence, DOE does not infer from those results that modern clothes dryers spend negligible time in inactive mode, and the findings are by themselves inconclusive regarding the time modern clothes dryers spend in delay start mode.

National Appliance and Equipment Energy Efficiency Committee

(NAEEEC) of Australia (October 2003). Available at: http:// www.energyrating.gov.au/library/pubs/sb200309-dryers.pdf.

A different study on clothes washers provides some additional evidence suggesting a small number of hours associated with clothes dryer delay start mode.\14\ This study monitored time clothes washers in Australia and New Zealand spent in different modes, and showed that the average amount of time spent in delay start mode per wash cycle was approximately 5 minutes. DOE believes that the results for clothes washers may be applicable for clothes dryers as well, because of the similarities between the control capabilities for both types of products and comparable consumer usage patterns when a clothing load is washed and dried.

\14\ ``A Submission to NAEEEC on Mode Times for Use When

Determining Standby Energy Consumption of Clothes Washers,

Dishwashers, and Dryers,'' Australian Electrical and Electronic

Manufacturers' Association (March 11, 2005), Appendix B.

Based on these two information sources, DOE has tentatively concluded that a typical modern clothes dryer spends a small amount of time in delay start mode. Using an estimated 5 minutes per cycle, the total annual amount of time spent in delay start mode using the representative 416 cycles per year is 34 hours. The remaining time not associated with active mode or delay start mode can be split as suggested by the Australian study: 5 percent allocated to cycle finished mode and 95 percent allocated to off or inactive mode.

Table III.1 presents a comparison of the annual energy use associated with all modes. The approximate range of wattages associated with the standby and off modes are based on the references cited previously in this section and on ``Clothes Dryers Background/Issues/

Standby,'' presented by Robert Foster of Energy Efficiency Strategies at the E3 White Goods Forum in Sydney, Australia, in February 2007.\15\

Active mode annual energy use is calculated based on 416 cycles per year in a standard-size electric dryer with a minimum standard EF of 3.01. Per-cycle energy use for such a clothes dryer is calculated as 7 pounds (lbs) divided by 3.01 lbs per kilowatt-hour (kWh), which is equal to 2.33 kWh. The typical average power level during active mode is calculated as 967 kWh per year of annual energy use divided by 140 hours in active mode, which is equal to 6,907 W.

To determine the annual hours per mode for clothes dryers for which not all standby modes are possible, DOE estimated values based upon reallocating the hours for modes that are not present according to the ratios discussed previously (i.e., that cycle finished mode, if present, would account for 5 percent of annual hours not allocated to active and delay start modes, and off/inactive modes would account for the remaining 95 percent). DOE's logic for this distribution of hours is as follows:

If delay start is not possible, cycle finished mode would be 0.05 x (8,760 total hours-140 active mode hours) = 431 hours. The remaining 8,189 hours would be allocated for off/inactive modes.

If cycle finished mode is not possible, delay start mode, which is assumed to be a fixed value of 5 minutes per cycle for each of the 416 cycles per

Page 74648

year specified in the DOE test procedure, would account for 34 hours.

Thus, off/inactive modes would be 8,760 total hours-140 active mode hours-34 delay start mode hours = 8,586 hours.

If neither delay start nor cycle finished modes are possible, then off/inactive modes would simply be 8,760 total hours-140 active mode hours = 8,620 hours.

Information to guide allocation of the hours for clothes dryers that have both inactive and off modes is currently unavailable. Two operational scenarios exist: (1) A clothes dryer reverts to an off mode after a specified time in inactive mode; or (2) a clothes dryer stays in inactive mode unless the user switches the appliance back to off mode. DOE does not have information regarding the percentage of clothes dryers being sold that fall into each of these categories. DOE welcomes comment and additional information on this point. Because of this limitation, for purposes of its analysis, DOE proposes to allocate half of the hours determined for off/inactive modes to each of the two modes.

In summary, DOE proposes to calculate clothes dryer energy use per cycle associated with standby and off modes by: (1) Calculating the product of wattage and allocated hours for all possible standby and off modes; (2) summing the results; (3) dividing the sum by 1,000 to convert from Wh to kWh; and (4) dividing by 416 cycles per year. The number of hours for off/inactive modes would be allocated entirely to either off mode or inactive mode, as appropriate, if only one of these modes is possible for the clothes dryer. If both modes are possible, the off/inactive mode hours would be divided evenly between the two.

DOE invites comments on this proposed methodology and associated factors, including accuracy, allocation of annual hours, and test burden. If, based on comments, DOE determines that this approach is unreasonable, DOE would consider the following alternative methodology.

The comparison of annual energy use of different clothes dryer modes shows that delay start and cycle finished modes represent a relatively small number of hours at low power consumption levels. For clothes dryers currently on the market, these levels are distinct from but comparable to those for off/inactive modes. Thus, DOE could adopt an approach that would be limited to specification of hours for only off and inactive modes when calculating energy use associated with standby and off modes. In that case, all of the non-active hours (8,620 hours total) would be allocated to the inactive and off modes. DOE invites comment on whether such an alternative would be representative of the standby and off mode power consumption of clothes dryers currently on the market. 2. Room Air Conditioners

DOE is not aware of reliable data for hours spent in different standby and off modes in room air conditioners. Therefore, DOE estimated relative magnitudes of energy use in standby and off modes in the following example, illustrated for a representative 8,000 Btu/hour

(hr), 9 EER unit that has delay start, off-cycle, and inactive modes.

DOE is aware that a room air conditioner may be unplugged for a certain percentage of time, and, therefore, will not be in either standby mode or off mode. DOE does not have data regarding the amount of ``unplugged'' time for a typical room air conditioner. For the purposes of this analysis, DOE estimates that approximately half of room air conditioners are unplugged for half of the year. The

``unplugged'' time associated with these units is averaged over all units. Hence, the average number of plugged-in hours per year for a room air conditioner would be estimated as 8,760 total hours - (\1/2\ of units that are unplugged x 4,380 unplugged hours) = 6,570 hours.

The prime cooling season is estimated to last 90 days a year, which equals 2,160 hours. During this time, it is estimated that room air conditioners spend 750 hours in cooling mode, according to the current test procedure. In addition, DOE estimates that 10 percent of room air conditioners that have a delay start mode function will use this function for 10 hours a day during the cooling season. Averaged over all units with this functionality, this represents 90 days x 10 hr/day x 10 percent of units = 90 hours. Therefore, cooling mode hours plus delay start hours total 840 hours for units that incorporate the delay start function. The remaining cooling season hours in this example are 2,160 cooling season hours - 840 combined cooling mode and delay start mode hours = 1,320 hours. For this representative unit, DOE assumes that these remaining cooling season hours divide equally into: (1) Fan- only mode (an active mode in which the compressor shuts down when operating in constant-fan mode or user selection of fan-only operation); (2) off-cycle mode; and (3) inactive mode (and/or off mode for units that have such capability). One-third of 1,320 equals 440, so for this example, the number of off-cycle mode hours is 440, and the number of inactive and/or off mode hours during the cooling season is also 440.

The cooling season inactive and/or off mode hours are summed with the additional inactive and/or off mode hours when the unit is plugged in outside of the cooling season. These additional hours are 6,570 plugged-in hours - 2,160 cooling season hours = 4,410 hours. Hence, for this example, total inactive and/or off mode hours are 440 inactive and/or off mode hours during cooling season + 4,410 plugged-in hours outside of the cooling season = 4,850 hours. The hours for the relevant modes and estimates of power input and energy use for this example are summarized in Table III.3 below.

Page 74649

While the hours per mode presented in this illustration are estimates based on limited study data, DOE believes that energy patterns illustrated in this example are representative for most room air conditioners with delay start and off-cycle mode capability. The typical average power level during active mode is calculated as the 8,000 Btu/hr cooling capacity / 9 Btu/hr/W EER = 889 W.

To determine the annual hours per mode for room air conditioners for which not all standby modes are possible, DOE estimated values based upon reallocating the hours for modes that are not present according to the ratios discussed previously (i.e., that off-cycle mode, if present, would account for one-third of annual cooling season hours not allocated to active and delay start modes, and off/inactive modes would account for another one third of the annual cooling season hours not allocated to active and delay start modes plus the 4,410 plugged-in non-cooling season hours). DOE's logic for this distribution of hours is as follows:

If delay start is not possible, off-cycle mode would equal

\1/3\ x (2,160 cooling season hours - 750 cooling mode hours) = 470 hours. Off/inactive modes would then account for 470 off-cycle mode hours + 4,410 plugged-in non-cooling season hours = 4,880 hours.

If off-cycle mode is not possible, off/inactive modes would equal \1/2\ x (2,160 cooling season hours - 750 cooling mode hours - 90 delay start mode hours) + 4,410 plugged-in non-cooling season hours = 5,070 hours.

If neither delay start nor off-cycle modes are possible, then off/inactive modes would equal \1/2\ x (2,160 cooling season hours

- 750 cooling mode hours) + 4,410 plugged-in non-cooling season hours = 5,115 hours.

** (2,160 cooling season hours - 750 cooling mode hours - delay start mode hours) divided by the number of these three modes which are present (fan-only, off-cycle, and off/inactive). Off and inactive modes are treated as one, and also include all of the 4,410 plugged in hours outside of the cooling season.

DOE is unaware of any room air conditioners that incorporate both off and inactive modes. Typically, room air conditioners with remote control can be controlled whenever they are plugged in; hence, these units do not include an off mode. If a room air conditioner allows the user to switch off remote control operation, such a product would be capable of both inactive and off mode. For these units, DOE proposes that the plugged-in off/inactive hours be allocated equally to the inactive and off modes for such a product.

In summary, DOE proposes to calculate room air conditioner energy use associated with standby and off modes by: (1) Calculating the products of wattage and allocated hours for all possible standby and off modes; (2) summing the results; and (3) dividing the sum by 1,000 to convert from Wh to kWh. The number of allocated hours for off/ inactive modes would be allocated entirely to either off mode or inactive mode, as appropriate, if only one of these modes is possible for the room air conditioner. If both modes are possible, the off/ inactive mode hours would be divided evenly between the two.

Similar to clothes dryers, the comparison of annual energy use of different room air conditioner modes shows that delay start and off- cycle modes represent a relatively small number of hours at low power consumption levels. For room air conditioners currently on the market, these levels are distinct from but comparable to those for off/inactive modes. Thus, DOE could adopt an approach that would be limited to specification of hours for only off and inactive modes when calculating energy use associated with standby and off modes. In that case, all of the non-active hours (5,115 hours total) would be allocated to the inactive and off modes. DOE invites comment on whether such an alternative would be representative of the standby and off mode power consumption of room air conditioners currently on the market.

G. Measures of Energy Consumption

The DOE test procedures for clothes dryers and room air conditioners currently provide for the calculation of

Page 74650

several measures of energy consumption. For clothes dryers, the test procedure incorporates various measures of per-cycle energy consumption, including total per-cycle electric dryer energy consumption, per-cycle gas dryer electrical energy consumption, per- cycle gas dryer gas energy consumption, per-cycle gas dryer continuously burning pilot light gas energy consumption, total per- cycle gas dryer gas energy consumption expressed in Btu, and total per- cycle gas dryer gas energy consumption expressed in kWh. 10 CFR part 430, subpart B, appendix D, sections 4.1-4.5. The test procedure also provides an EF, which is equal to the clothes load in pounds divided by either the total per-cycle electric dryer energy consumption or by the total per-cycle gas dryer energy consumption expressed in kWh. 10 CFR 430.23(d). For room air conditioners, the test procedure calculates annual energy consumption in kWh and an EER. 10 CFR 430.23(f).

Under 42 U.S.C. 6295(gg)(2)(A), EPCA directs that the ``[t]est procedures for all covered products shall be amended pursuant to section 323 to include standby mode and off mode energy consumption, taking into consideration the most current versions of Standards 62301 and 62087 of the International Electrotechnical Commission, with such energy consumption integrated into the overall energy efficiency, energy consumption, or other energy descriptor for each covered product, unless the Secretary determines that--(i) the current test procedures for a covered product already fully account for and incorporate the standby mode and off mode energy consumption of the covered product; or (ii) such an integrated test procedure is technically infeasible for a particular covered product, in which case the Secretary shall prescribe a separate standby mode and off mode energy use test procedure for the covered product, if technically feasible.''

DOE explored whether the existing measures of energy consumption for clothes dryers and room air conditioners can be combined with standby mode and off mode energy use to form a single metric. DOE notes that certain test procedures combine measures of energy consumption and standby energy use to derive an overall ``energy efficiency measure''

(e.g., gas kitchen ranges and ovens incorporate pilot gas consumption in EF, electric ovens include clock power in EF, and gas clothes dryers include pilot gas consumption). When the difference in energy use between the primary function of those products and the standby power is so large that the standby power has little impact on the overall measure of energy efficiency, as is the case for clothes dryers and room air conditioners (illustrated in section III.F), the combined measure of energy efficiency is a meaningful measure. Therefore, DOE is proposing a combined metric addressing active, standby, and off modes for clothes dryers and room air conditioners, as discussed below. 1. Clothes Dryers

DOE proposes to establish the following measures of energy consumption for clothes dryers that integrate energy use of standby and off modes with energy use of main functions of the products. ``Per- cycle integrated total energy consumption expressed in kWh'' will be defined as the sum of per-cycle standby and off mode energy consumption and either total per-cycle electric dryer energy consumption or total per-cycle gas dryer energy consumption expressed in kWh, depending on which type of clothes dryer is involved. ``Integrated energy factor''

(IEF) will be defined as the (clothes dryer test load weight in lb)/

(per-cycle integrated total energy in kWh). 2. Room Air Conditioners

DOE proposes to establish the following measures of energy consumption for room air conditioners that integrate energy use of standby and off modes with energy use of main functions of the products. ``Integrated annual energy consumption'' will be defined as the sum of annual energy consumption and standby and off mode energy consumption. ``Integrated energy efficiency ratio'' (IEER) will be defined as (cooling capacity in Btu/hr x 750 hours average time in cooling mode) / (integrated annual energy consumption x 1,000 Wh per kWh).

H. Correction of Text Describing Energy Factor Calculation for Clothes

Dryers

Specific references used in the current DOE test procedure regulation contain certain errors that today's proposal seeks to correct. In particular, the reference to sections 2.6.1 and 2.6.2 of 10

CFR part 430, subpart B, appendix D in the calculation of EF for clothes dryers found at section 430.23(d)(2) is incorrect and should refer instead to sections 2.7.1 and 2.7.2. Section 2.6 provides instructions for the test clothes to be used in energy testing of clothes dryers, whereas section 2.7 provides instructions on test loads. The EF of clothes dryers is measured in pounds of clothes per kWh. Since the EF calculation requires the weight of the test load, DOE proposes to correct these references in 10 CFR 430.23(d)(2).

I. Correction of Text Referencing Room Air Conditioner Test Standard

The room air conditioner test procedure currently references ASHRAE

Standard 16-69, ``Method of Testing for Rating Room Air Conditioners.''

The text in 10 CFR part 430, subpart B, appendix F, section 1, however, incorrectly identifies ASHRAE as ``American Society of Heating,

Refrigerating and Air Conditioning in Engineers.'' The actual name of the referenced organization is ``American Society of Heating,

Refrigerating and Air-Conditioning Engineers.'' DOE proposes to correct this reference in 10 CFR part 430, subpart B, appendix F, section 1

(which is being redesignated as section 2 in the proposed amendments).

J. Compliance With Other EPCA Requirements 1. Test Burden

Section 323(b)(3) of EPCA requires that ``[a]ny test procedures prescribed or amended under this section shall 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 shall not be unduly burdensome to conduct.'' (42 U.S.C. 6293(b)(3)) For the reasons that follow, DOE has tentatively concluded that amending the relevant DOE test procedures to incorporate clauses regarding test conditions and methods found in IEC Standard 62301, along with the proposed modifications, would satisfy this requirement.

The proposed amendments to the DOE test procedure incorporate a test standard that is accepted internationally for measuring standby power in standby modes and off mode. Based on DOE's testing and analysis of IEC Standard 62301, DOE determined that the proposed amendments to the clothes dryer and room air conditioner test procedures would produce standby and off mode average power consumption measurements that are representative of an average use cycle, both when the measured power is stable and when the measured power is unstable

(i.e., when power varies by more than 5 percent during 5 minutes).

Also, the test methods and equipment that the amendment would require for measuring standby power in these products are not substantially different from, or can be even less burdensome to implement than, the test methods and

Page 74651

equipment in the current DOE test procedures for measuring the products' energy consumption. Therefore, the proposed test procedures would not require manufacturers to make a major investment in test facilities and new equipment. Accordingly, DOE has tentatively concluded that the amended test procedures would produce test results that measure the standby/off mode power consumption of a covered product during a representative average use cycle, as well as total annual energy consumption, and that testing under the test procedures would not be unduly burdensome to conduct. 2. Potential Incorporation of IEC Standard 62087

Section 325(gg)(2)(A) of EPCA directs DOE to consider IEC Standard 62087 when amending test procedures to include standby mode and off mode power measurements (42 U.S.C. 6295(gg)(2)(A)). As discussed in section III.C of this notice, DOE reviewed IEC Standard 62087 ``Methods of measurement for the power consumption of audio, video, and related equipment'' (Second Edition 2008-09) and determined that it would not be applicable to measuring power consumption of electrical appliances such as clothes dryers and room air conditioners. Therefore, DOE has determined that referencing IEC Standard 62087 is not necessary for the proposed amendments to the test procedures that are the subject of this rulemaking. 3. Integration of Standby Mode and Off Mode Energy Consumption Into the

Efficiency Metrics

Section 325(gg)(2)(A) requires that standby mode and off mode energy consumption be ``integrated into the overall energy efficiency, energy consumption, or other energy descriptor for each covered product'' unless the current test procedures already fully account for the standby mode and off mode energy consumption or if such an integrated test procedure is technically infeasible (42 U.S.C. 6295(gg)(2)(A)). For clothes dryers, DOE is proposing to incorporate the standby and off mode energy consumption into a ``per-cycle integrated total energy consumption expressed in kilowatt-hours'' and into an IEF, as discussed in section III.G of this notice. For room air conditioners, DOE is proposing to incorporate the standby and off mode energy consumption into a metric for ``integrated annual energy consumption'' and into an IEER, as discussed in section III.G.

Furthermore, EPCA provides that test procedure amendments adopted to comply with the new EPCA requirements for standby and off mode energy consumption will not determine compliance with previously established standards. (42 U.S.C. 6295(gg)(2)(C)) Pursuant to this provision, the test procedure amendments pertaining to standby mode and off mode energy consumption that DOE proposes to adopt in this rulemaking would not apply to, and would have no impact on, existing standards. In other words, existing energy standards for clothes dryers and room air conditioners, which are based on EF and EER, respectively, would not be altered by today's proposal. Instead, the test procedures' provisions for standby/off mode would be required to be used for demonstrating compliance with DOE's energy conservation standards upon the effective date of a subsequent standards rulemaking for clothes dryers and room air conditioners that account for standby mode and off mode power consumption. Thus, the proposed test procedure amendments comply with this EPCA requirement.

IV. Procedural Requirements

A. Review Under Executive Order 12866

Today's proposed regulatory action is not a ``significant regulatory action'' under section 3(f) of Executive Order 12866,

Regulatory Planning and Review, 58 FR 51735 (Oct. 4, 1993).

Accordingly, this proposed 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 (OMB).

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 for any rule that by law must be proposed for public comment, unless the agency certifies that the proposed 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 rulemaking process. 68 FR 7990. DOE's procedures and policies may be viewed on the Office of the General Counsel's Web site (http://www.gc.doe.gov).

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 products that are the subject of this rulemaking.

DOE has tentatively concluded that the proposed rule would not have a significant impact on either small or large manufacturers under the provisions of the Regulatory Flexibility Act. The proposed rule would amend DOE's test procedures by incorporating testing provisions to address standby mode and off mode energy consumption. The procedures involve measuring power input when the clothes dryer or room air conditioner is in standby and off modes during testing. These tests can be conducted in the same facilities used for the current energy testing of these products, but could also be conducted in separate facilities consisting of little more than a temperature-controlled space. The power meter required for these tests might require greater accuracy than the power meter used for current energy testing, but the investment required for a possible instrumentation upgrade would be modest. The duration of the standby and off mode testing is relatively short in comparison to the time required to conduct current energy testing. Thus, such requirements for equipment and time to conduct the additional tests would not be expected to impose a significant economic impact. Accordingly, DOE does not believe that the proposed rule would have a significant economic impact on entities subject to the applicable testing requirements.

Further, the Small Business Administration (SBA) considers an entity to be a small business if, together with its affiliates, it employs less than a threshold number of workers specified in 13 CFR part 121, which relies on size standards and codes established by the

North American Industry Classification System (NAICS). The threshold number for NAICS classification for 335224, which applies to household laundry equipment manufacturers and includes clothes dryer manufacturers, is 1,000 employees. Additionally, two other NAICS classifications could apply to manufacturers involved in the production of room air conditioners, including 333415 (air conditioning and warm air heating equipment and commercial and industrial refrigeration equipment) and 335228 (other major household appliance manufacturing).

The employee thresholds for

Page 74652

classification as a small entity under these NAICS codes are 750 and 500 employees, respectively.

Searches of the SBA Web site \16\ to identify manufacturers within these NAICS codes that manufacture clothes dryers and/or room air conditioners identified only Staber Industries of Groveport, Ohio as a relevant manufacturer. Staber manufactures laundry appliances, including clothes dryers. Most of the manufacturers supplying clothes dryers and room air conditioners are large multinational corporations.

Only one small entity could be identified that could be affected by this test procedure modification, out of approximately 15 manufacturers supplying clothes dryers in the United States, and, for the reasons stated above, the incremental impacts on that manufacturer arising from the new proposed test procedure requirements are expected to be small.

\16\ A searchable database of certified small businesses is available online at: http://dsbs.sba.gov/dsbs/search/dsp_dsbs.cfm.

For these reasons, DOE tentatively concludes and certifies that the 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

This proposed rulemaking will impose no new information collection or recordkeeping requirements. Accordingly, OMB clearance is not required under the Paperwork Reduction Act. (44 U.S.C. 3501 et seq.)

D. Review Under the National Environmental Policy Act of 1969

In this notice, DOE is proposing test procedure amendments that it expects would be used to develop and implement future energy conservation standards for clothes dryers and room air conditioners.

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 rule amends an existing rule without changing its environmental effect, and, therefore, is covered by the Categorical Exclusion in 10 CFR part 1021, subpart D, paragraph A5, which applies because this rule would establish revisions to existing test procedures that would not affect the amount, quality, or distribution of energy usage, and, therefore, would not result in any environmental impacts. Accordingly, neither an environmental assessment nor an environmental impact statement is required.

E. Review Under Executive Order 13132

Executive Order 13132, ``Federalism,'' imposes certain requirements on agencies formulating and implementing policies or regulations that preempt State law or that have Federalism implications. 64 FR 43255

(August 10, 1999). 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 that it will follow in developing such regulations. 65 FR 13735. DOE examined this proposed rule and determined that it would not preempt State law and 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.

Therefore, Executive Order 13132 requires no further action.

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 specifies the following: (1) The preemptive effect, if any; (2) any effect on existing Federal law or regulation; (3) a clear legal standard for affected conduct while promoting simplification and burden reduction; (4) the retroactive effect, if any; (5) definitions of key terms; and (6) 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 whether it is unreasonable to meet one or more of them.

DOE has completed the required review and determined that, to the extent permitted by law, this 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) (Pub.

L. 104-4; 2 U.S.C. 1501 et seq.) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and Tribal governments and the private sector. 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 estimates of the resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a),(b)) 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 such governments. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental consultation under UMRA. 62 FR 12820. (The policy is also available at http://www.gc.doe.gov). Today's proposed rule contains neither an intergovernmental mandate nor a mandate that may result in an expenditure of $100 million or more in 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

Page 74653

that may affect family well-being. Today's proposed 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 proposed regulation would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution.

J. Review Under the Treasury and General Government Appropriations Act, 2001

Section 515 of the Treasury and General Government Appropriations

Act, 2001 (44 U.S.C. 3516 note) provides for 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 notice under 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 OIRA a Statement of Energy Effects for any proposed significant energy action. A ``significant energy action'' is defined as any action by an agency that promulgates or is expected to lead to promulgation of a final rule, and that: (1) Is a significant regulatory action under

Executive Order 12866, or any successor order; and (2) is likely to have a significant adverse effect on the supply, distribution, or use of energy; or (3) is designated by the Administrator of OIRA as a significant energy action. For any proposed significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use if the proposal is implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use. Today's proposed regulatory action is not a significant regulatory action under Executive Order 12866. It has likewise not been designated as a significant energy action by the Administrator of OIRA. Moreover, it would not have a significant adverse effect on the supply, distribution, or use of energy. 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 DOE Organization Act (Pub. L. 95-91; 42

U.S.C. 7101 et seq.), 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 (FEAA). (15 U.S.C. 788)

Section 32 essentially provides in part that, where a proposed rule authorizes or requires use of commercial standards, the 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 modifications to the test procedures addressed by this proposed action incorporate testing methods contained in the commercial standard, IEC Standard 62301. DOE has evaluated this standard and is unable to conclude whether it fully complies with the requirements of section 32(b) of the FEAA (i.e., whether it was 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 about the impact on competition of using the methods contained in this standard, before prescribing a final rule.

E. Issues on Which DOE Seeks Comment

DOE is particularly interested in receiving comments and views of interested parties on the following issues: 1. Incorporation of IEC Standard 62301. DOE invites comment on the adequacy of IEC Standard 62301 to measure standby power for clothes dryers and room air conditioners in general, and on the suitability of incorporating into DOE regulations the specific provisions described in section III of this notice. 2. ``Standby mode'' definitions. DOE invites comment on the differences in definition of ``standby mode'' provided by EPCA and the definition provided in the current version of IEC Standard 62301. 3. Clothes dryer standby modes. DOE invites comment on the establishment of the following specific standby modes for clothes dryers: Inactive mode, delay start mode, and cycle finished mode. DOE further invites comment on the definitions proposed for these modes and on the question of whether there are any modes consistent with the

``active mode,'' ``standby mode,'' or ``off mode'' definitions under

EPCA that have not been identified and that can represent significant energy use. 4. Room air conditioner standby modes. DOE invites comment on the establishment of the following specific standby modes for room air conditioners: Inactive mode, delay start mode, and off-cycle mode. DOE further invites comment on the definitions proposed for these modes and on the question of whether there are any modes consistent with the

``active mode,'' ``standby mode,'' or ``off mode'' definitions under

EPCA that have not been identified and that can represent significant energy use. 5. Delay start test procedure. DOE seeks comment on the proposed clarification to IEC Standard 62301, in which DOE would specify in the clothes dryer and room air conditioner test procedures, the set delay start time, stabilization period, and test duration for delay start mode power measurements. (See section III.E of this notice.) 6. Test room conditions. DOE requests comment on the proposed room ambient temperature range for standby mode and off mode power measurements for room air conditioners and clothes dryers. (See section

III.E of this notice.) 7. Energy use calculation for standby mode and off mode for clothes dryers. DOE invites comment on the approach for determining total energy use for standby mode and off mode for clothes dryers, including its accuracy and test burden. Given that individual units may be capable of different combinations of standby modes, DOE also invites comment and requests data on the estimates for annual hours associated with each mode, including the 140 hours specified by the current test procedure for active mode (drying). 8. Energy use calculation for standby mode and off mode for room air conditioners. DOE invites comment on the approach for determining total energy use for standby mode and off mode for room air conditioners, including its accuracy and test burden. Given that individual units may be capable of different combinations of standby modes, DOE also invites comment and requests data on the estimates for annual hours associated with each mode, including the estimate of

``unplugged'' time. 9. New integrated measures of energy consumption and energy efficiency. DOE invites comment on the proposed plan to establish new integrated measures of energy consumption and energy efficiency for clothes dryers and room air conditioners: ``Per-cycle integrated total energy consumption expressed in kilowatt-hours'' and ``integrated energy factor'' for clothes dryers; and ``integrated annual energy consumption'' and ``integrated energy efficiency ratio'' for room air conditioners.

VI. Approval of the Office of the Secretary
