Energy Conservation Program for Consumer Products: Test Procedures for Residential Dishwashers, Dehumidifiers, and Conventional Cooking Products (Standby Mode and Off Mode)

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy.
ACTION: Notice of proposed rulemaking and announcement of public meeting.
SUMMARY: In order to implement recent amendments to the Energy Policy and Conservation Act of 1975 (EPCA), the U.S. Department of Energy (DOE) proposes to amend its test procedures for residential dishwashers, dehumidifiers, and conventional cooking products (which include cooktops, ovens, and ranges) to provide for measurement of standby mode and off mode energy use by these products. The proposed 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 (IEC Standard 62301 (First Edition)). DOE also proposes to adopt definitions of various modes of operation based on the relevant provisions from the IEC Standard 62301 "Household electrical appliances--Measurement of standby power," Second Edition Final Draft International Standard (IEC Standard 62301 (FDIS)). In addition, DOE proposes to adopt language to clarify application of these test procedure provisions for measuring standby mode and off mode power consumption in dishwashers, dehumidifiers, and conventional cooking products. Furthermore, the proposed amendments would add new calculations to determine annual energy consumption associated with the standby mode and off mode measured power. Finally, the amendments would modify existing energy consumption equations to integrate standby mode and off mode energy consumption into the calculation of overall annual energy consumption and annual operating cost of those products which already have definitions for such measures (dishwashers and conventional cooking products). DOE is also announcing a public meeting to discuss and receive comments on the issues presented in this notice.
DATES: Meeting:DOE will hold a public meeting on Friday, December 17, 2010, from 9 a.m. to 4 p.m., in Washington, DC. DOE must receive requests to speak at the public meeting before 4 p.m., Friday, December 3, 2010. DOE must receive a signed original and an electronic copy of statements to be given at the public meeting before 4 p.m., Friday, December 10, 2010.

Title III, Part B of the Energy Policy and Conservation Act of 1975 (EPCA), Public Law 94-163 (42 U.S.C. 6291-6309, as codified), established the “Energy Conservation Program for Consumer Products Other Than Automobiles,” a program covering most major household appliances, including residential dishwashers, conventional cooking products, and dehumidifiers,1 the subjects of today's notice.2 (42 U.S.C. 6292(a)(6) and (10); 6295(cc)) Under the Act,3 this program consists essentially of three parts: (1) Testing; (2) labeling; and (3) Federal energy conservation standards.

1The term “conventional cooking products,” as used in this notice, refers to residential electric and gas kitchen ovens, ranges, and cooktops (other than microwave ovens).

2For editorial reasons, upon codification in the U.S. Code, Part B was re-designated as Part A.

3All references to EPCA refer to the statute as amended, including through the Energy Independence and Security Act of 2007, Public Law 110-140.

Manufacturers of covered products must use DOE test procedures, prescribed under EPCA, to certify that their products comply with the energy conservation standards adopted under EPCA and to represent the energy consumption or energy efficiency of their products. (42 U.S.C. 6293(c); 42 U.S.C. 6295(s)) DOE must also use DOE test procedures in any enforcement action to determine whether covered products comply with these energy conservation standards. (42 U.S.C. 6295(s)) Criteria and procedures for DOE's adoption and amendment of such test procedures, as set forth in EPCA, require that test procedures 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. Test procedures must also not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))

If DOE determines that a test procedure amendment is warranted, it must publish proposed test procedures and offer the public an opportunity to present oral and written comments on them. (42 U.S.C. 6293(b)(2)) 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))

Dishwashers

DOE's test procedure for dishwashers is found in the Code of Federal Regulations (CFR) at 10 CFR part 430, subpart B, appendix C. DOE originally established its test procedure for dishwashers in 1977. 42 FR 39964 (August 8, 1977). Since that time, the dishwasher test procedure has undergone a number of amendments, as discussed below. In 1983, DOE amended the test procedure to revise the representative average-use cycles to more accurately reflect consumer use and to address dishwashers that use 120 °F inlet water. 48 FR 9202 (March 3, 1983). DOE amended the test procedure again in 1984 to redefine the term “water heating dishwasher.” 49 FR 46533 (Nov. 27, 1984). In 1987, DOE amended the test procedure to address models that use 50 °F inlet water. 52 FR 47549 (Dec. 15, 1987). In 2001, DOE revised the test procedure's testing specifications to improve testing repeatability, changed the definitions of “compact dishwasher” and “standard dishwasher,” and reduced the average number of use cycles per year from 322 to 264. 66 FR 65091, 65095-97 (Dec. 18, 2001). In 2003, DOE again revised the test procedure to more accurately measure dishwasher efficiency, energy use, and water use. The 2003 dishwasher test procedure amendments included the following revisions: (1) The addition of a method to rate the efficiency of soil-sensing products; (2) the addition of a method to measure standby power; and (3) a reduction in the average-use cycles per year from 264 to 215. 68 FR 51887, 51899-903 (August 29, 2003). The current version of the test procedure includes provisions for determining estimated annual energy use (EAEU), estimated annual operating cost (EAOC), energy factor (EF) expressed in cycles per kilowatt-hour (kWh), and water consumption expressed in gallons per cycle. (10 CFR 430.23(c))

The National Appliance Energy Conservation Act of 1987 (NAECA), Public Law 100-12, amended EPCA to establish prescriptive standards for dishwashers, requiring that dishwashers manufactured on or after January 1, 1988, be equipped with an option to dry without heat. (42 U.S.C. 6295(g)(1)) These EPCA amendments also mandated that DOE must conduct two rounds of rulemaking to determine whether the energy conservation standards for dishwashers should be amended. (42 U.S.C. 6295(g)(4)) On May 14, 1991, DOE issued a final rule establishing the first set of performance standards for dishwashers. 56 FR 22250. The final rule required that dishwashers manufactured on or after May 14, 1994, must have a minimum EF of 0.46 cycles per kWh for standard size, and 0.62 cycles per kWh for compact size.Id.at 22279; 10 CFR 430.32(f)(1).

The Energy Independence and Security Act of 20074 (EISA 2007) further amended EPCA, in relevant part by establishing the following energy conservation standards for residential dishwashers manufactured on or after January 1, 2010: (1) For standard sizedishwashers, a maximum annual energy use of 355 kWh per year, and a maximum water consumption of 6.5 gallons per cycle; and (2) for compact dishwashers, a maximum annual energy use of 260 kWh per year, and a maximum water consumption of 4.5 gallons per cycle. (42 U.S.C. 6295(g)(10)(A); 10 CFR 430.32(f)(2)) The amendments also specify that not later than January 1, 2015, the Secretary shall publish a final rule determining whether to amend the standards for dishwashers manufactured on or after January 1, 2018. (42 U.S.C. 6295(g)(10)(B))

4Public Law. 110-140 (enacted Dec. 19, 2007).

Dehumidifiers

The DOE test procedure for dehumidifiers is found at 10 CFR 430, subpart B, appendix X. The Energy Policy Act of 2005 (EPACT 2005), Public Law 109-58, amended EPCA to specify that the U.S. Environmental Protection Agency's (EPA) test criteria used under the ENERGY STAR® 5 program must serve as the basis for the test procedure for dehumidifiers. (EPACT 2005, section 135(b); 42 U.S.C. 6293(b)(13)) The ENERGY STAR test criteria require that American National Standards Institute (ANSI)/Association of Home Appliance Manufacturers (AHAM) Standard DH-1-2003, “Dehumidifiers,” be used to measure energy use and that the Canadian Standards Association (CAN/CSA) standard CAN/CSA-C749-1994 (R2005), “Performance of Dehumidifiers,” be used to calculate EF. DOE has adopted these test criteria, along with related definitions and tolerances, as its test procedure for dehumidifiers. 71 FR 71340, 71347, 71366-68 (Dec. 8, 2006). The DOE test procedure provides methods for determining the EF for dehumidifiers, which is expressed in liters (l) of water condensed per kWh.

5For more information on the ENERGY STAR program,see: http://www.energystar.gov.

Section 135(c)(4) of EPACT 2005 added dehumidifiers as products covered under EPCA and established standards effective for dehumidifiers manufactured on or after October 1, 2007. (42 U.S.C. 6295(cc)(1)) Section 311 of EISA 2007 further amended EPCA to revise the energy conservation standards for dehumidifiers, establishing the following minimum EFs based on product capacity for dehumidifiers manufactured on or after October 1, 2012:

Table I.1—October 2012 Dehumidifier Energy Conservation Standards * Product capacity
  • (pints/day)
  • Minimum EF
  • (liters/kWh)
  • Up to 35.00 1.35 35.01-45.00 1.50 45.01-54.00 1.60 54.01-75.00 1.70 75.00 or more 2.5 * (42 U.S.C. 6295(cc)(2)).
    Conventional Cooking Products

    DOE's test procedures for conventional ranges, cooktops, and ovens (including microwave ovens) are found at 10 CFR 430, subpart B, appendix I. DOE first established the test procedures included in appendix I in a final rule published in theFederal Registeron May 10, 1978. 43 FR 20108, 20120-28. DOE revised its test procedure for cooking products to more accurately measure their efficiency and energy use, and published the revisions as a final rule in 1997. 62 FR 51976 (Oct. 3, 1997). These test procedure amendments included: (1) A reduction in the annual useful cooking energy; (2) a reduction in the number of self-cleaning oven cycles per year; and (3) incorporation of portions of IEC Standard 705-1988, “Methods for measuring the performance of microwave ovens for household and similar purposes,” and Amendment 2-1993 for the testing of microwave ovens.Id.The test procedure for conventional cooking products establishes provisions for determining EAOC, cooking efficiency (defined as the ratio of cooking energy output to cooking energy input), and EF (defined as the ratio of annual useful cooking energy output to total annual energy input). (10 CFR 430.23(i); 10 CFR part 430 subpart B, appendix I) These provisions for conventional cooking products are not currently used for compliance with any energy conservation standards (because those standards currently involve design requirements), nor is there an EnergyGuide6 labeling program for cooking products.

    6For more information on the EnergyGuide labeling program,see: http://www.access.gpo.gov/nara/cfr/waisidx_00/16cfr305_00.html.

    DOE has initiated a separate test procedure rulemaking to address standby mode and off mode power consumption for microwave ovens. This rulemaking was initiated separately in response to comments from interested parties on the advance notice of proposed rulemaking (ANOPR) for an earlier rulemaking concerning energy conservation standards for dishwashers, dehumidifiers, cooking products, and commercial clothes washers published on November 15, 2007 (hereafter referred to as the November 2007 ANOPR) (72 FR 64432), prior to the enactment of EISA 2007. As discussed in the October 2008 test procedure NOPR, interested parties stated generally that DOE should amend the test procedures for all types of cooking products to allow for measurement of standby mode energy use in order to implement a standby power energy conservation standard. 73 FR 62034, 62043-44 (Oct. 17, 2008). However, DOE did not receive any specific data or inputs on standby power consumption in conventional cooking products. Also, at that time, interested parties did not submit any comments regarding DOE addressing new measures of standby mode and off mode energy use in the test procedures or energy conservation standards for the other products that were the subject of the November 2007 ANOPR (i.e.,dishwashers and dehumidifiers.) Because DOE agreed with the comments supporting new measures of standby mode and off mode energy use for microwave ovens and the potential for early adoption of an energy conservation standard for microwave ovens addressing standby mode and off mode energy consumption, DOE published a NOPR proposing amendments to just the microwave oven test procedure for standby mode and off mode in theFederal Registeron October 17, 2008. 73 FR 62134. DOE subsequently published a supplemental notice of proposed rulemaking (SNOPR) in theFederal Registeron this topic on July 22, 2010. 75 FR 42612. Consequently, DOE is proposing amendments to its cooking products test procedure for only conventional cooking products in today's NOPR.

    As with dishwashers, NAECA amended EPCA to establish prescriptive standards for cooking products. The NAECA amendments required gas ranges and ovens with an electrical supply cord manufactured on or after January 1, 1990, not to be equipped with a constant-burning pilot light. (42 U.S.C. 6295(h)(1)) Subsequently, DOE published a final rule in theFederal Registeron April 8, 2009, amending the energy conservation standard for cooking products to require for products manufactured on or after April 9, 2012, that gas cooking products without an electrical supply cord shall not be equipped with a constant burning pilot light. 74 FR 16040, 16094.

    Standby Mode and Off Mode

    Section 310 of EISA 2007 amended EPCA to require DOE to amend the test procedures for covered products to address standby mode and off mode energy consumption. Specifically, the amendments also require DOE to integrate standby mode and off mode energy consumption into the overall energy efficiency, energy consumption, or other energy descriptor for that product unless the current test procedures already fully account for such consumption. If integration 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 IEC Standards 62301, “Household electrical appliances—Measurement of standby power,” and IEC Standard 62087, “Methods of measurement for the power consumption of audio, video, and related equipment.”Id.For residential dishwashers, dehumidifiers, and conventional cooking products (and microwave ovens), DOE must prescribe any such amendment to the test procedures by final rule no later than March 31, 2011. (42 U.S.C. 6295(gg)(2)(B)(vi)) Furthermore, EISA 2007 also amended EPCA to direct DOE to incorporate standby mode and off mode energy use into any final rule establishing or revising an energy conservation standard for a covered product adopted after July 1, 2010. If it is not feasible to incorporate standby mode and off mode into a single amended or new standard, then the statute requires DOE to prescribe a separate standard to address standby mode and off mode energy consumption. (42 U.S.C. 6295(gg)(3))

    DOE notes that the IEC is in the process of developing a revised version of IEC Standard 62301, which was expected to be released by July 2009. This revision is expected to be significantly delayed until late 2010 at the earliest. In order to publish a final rule by March 31, 2011, DOE is proceeding with an amended test procedure based on the current version of IEC Standard 62301 (First Edition). However, DOE is also considering the updated mode of operation definitions in the latest draft version of IEC Standard 62301, IEC Standard 62301 (FDIS). Although not formally adopted, DOE is evaluating the substance of those definitions, which are expected to be included in the final revised IEC Standard 62301 (Second Edition).

    DOE acknowledges that the current dishwasher test procedure already includes definitions and testing methods for measuring standby mode power consumption similar to the IEC Standard 62301 (First Edition) provisions, but it does not include definitions and testing methods for measuring multiple standby modes and off mode power consumption. However, in today's NOPR, for the reasons discussed in section III.B, DOE proposes amendments to the current dishwasher test procedure in order to fully account for standby mode and off mode power consumption. These amendments would take into consideration the most current versions of IEC Standards 62301 and 62087.

    The current DOE dehumidifier test procedure does not address energy use when the product is in standby mode and off mode. For this reason, in today's NOPR, DOE is proposing amendments to its dehumidifier test procedure to provide for the measurement of standby mode and off mode energy consumption.

    The current DOE conventional cooking products test procedure does not fully account for standby mode and off mode energy consumption. However, DOE notes that the test procedures, as currently drafted, do account for standby energy use in narrow cases. The DOE conventional cooking products test procedures include provisions for determining the annual energy consumption of a continuously-operating clock, as well as the standby energy use associated with a continuously-burning pilot light for gas cooking products. Otherwise, the test procedure does not address energy use in standby mode or off mode. For this reason, in today's NOPR, DOE proposes amendments to the conventional cooking products test procedures to fully account for standby mode and off mode power consumption.

    II. Summary of the Proposal

    In today's NOPR, DOE proposes to amend the test procedures for dishwashers, dehumidifiers, and conventional cooking products in order to:

    (1) Provide a foundation for DOE to develop and implement standards that address use of standby mode and off mode power by these products; and

    (2) Address the statutory requirement to expand test procedures to incorporate measures of standby mode and off mode power consumption.

    In general, DOE proposes to incorporate by reference into the test procedures for these products specific provisions from IEC Standard 62301 (First Edition) regarding test conditions and test procedures for measuring standby mode and off mode power consumption, and to include language that would clarify the application of such provisions. DOE also proposes to incorporate into each test procedure the definitions of “active mode,” “standby mode,” and “off mode” that are based on the definitions for those terms provided in IEC Standard 62301 (FDIS). Further, DOE proposes to include in each test procedure additional language that would clarify the application of clauses from IEC Standard 62301 (First Edition) for measuring standby mode and off mode power consumption.7

    7EISA 2007 directs DOE to also consider IEC Standard 62087 when amending its test procedure to include standby mode and off mode energy consumption.See42 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.

    As an initial matter, DOE had to analyze a number of product-specific modes in order to determine whether they should be characterized as active mode, standby mode, or off mode functions. As discussed in further detail below, this rulemaking is limited to addressing standby mode and off mode. Based upon the results of its analyses, DOE is proposing the following product-specific amendments to the applicable DOE test procedures. For dishwashers, DOE is proposing definitions for the following different standby modes: (1) A general “inactive” mode; and (2) a “cycle finished” mode. For dehumidifiers, DOE is proposing definitions for the following different standby modes: (1) a general “inactive” mode; (2) an “off-cycle” mode; and (3) a “bucket full/removed” mode. For conventional cooking products, DOE is also proposing definitions for the following different standby modes: (1) A general “inactive” mode; and (2) a “cycle finished” mode. For each product, energy use in each standby mode, as well as energy use in the off mode, would be separately tested under the appropriate procedure and incorporated into an integrated energy efficiency metric for that product.

    The current DOE dishwasher test procedure already includes provisions for measuring standby power and includes it in the EAEU and EAOC calculations. However, as discussed earlier, DOE is proposing amendments to the dishwasher test procedure, pursuant to EPCA, to fully and more accurately account for standby mode and off mode power consumption based on provisions in IEC Standard 62301. As a result, DOE is proposing revisions to the EAEU and EAOC calculations toincorporate the revised measurements of standby mode and off mode power consumption into the combined metrics for dishwashers.

    For dehumidifiers, DOE is proposing in today's NOPR to:

    (1) Establish a new measure of energy use to calculate the annual standby mode and off mode energy use in dehumidifiers, based on the typical hours dehumidifiers spend in these modes; and

    (2) Adopt a new measure of energy efficiency (integrated energy factor (IEF)) that includes energy used in standby, off, and active modes for dehumidifiers.

    For conventional cooking products, the current DOE test procedure accounts for energy used by a constant clock display (if present), which is considered as part of standby mode under the proposed definition of “standby mode.” The current test procedure also accounts for standby mode energy use of a continuously-burning pilot light for gas conventional cooking products.8 However, DOE proposes in today's NOPR to amend the test procedure for conventional cooking products to fully account for all additional standby mode and off mode power consumption, as specified by provisions in IEC Standard 62301. DOE proposes in today's NOPR to: (1) Establish a new measure of energy use to calculate the annual standby mode and off mode energy consumption in conventional cooking products, and (2) adopt new measures of energy efficiency (IEF), annual energy consumption, and annual operating cost that include the energy used in all standby mode and off mode operations of conventional cooking products. In addition, DOE proposes additional clarifications to the testing methods for conventional cooking products to define the test duration for cases in which the measured power is not stable (i.e.,varies over a cycle). DOE acknowledges that the power consumption of conventional cooking product displays can vary based on the clock time being displayed, so today's proposal is drafted in a way to account for this fact, while still generating representative results.

    8DOE notes that it published a final rule in theFederal Registeron April 8, 2009, establishing standards that prohibit continuously-burning pilot lights for gas cooking products manufactured on or after April 9, 2012. 74 FR 16040, 16094.

    The statute also has other provisions regarding the inclusion of standby mode and off mode energy use in any energy conservation standard which have bearing on the current test procedure rulemaking. EPCA provides that amendments to the test procedures to include standby mode and off mode energy consumption shall not be used to determine compliance with product standards established prior to the adoption of the amended test procedures. (42 U.S.C. 6295(gg)(2)(C)) However, EPCA requires that DOE must determine to what extent, if any, the proposed test procedure would alter the measured energy efficiency, measured energy use, or measured water use 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 or measured energy use of a covered product, DOE must amend the applicable energy conservation standard during the rulemaking carried out with respect to the amended test procedure. In determining the amended energy conservation standard, the Secretary shall measure, pursuant to the amended test procedure, the energy efficiency, energy use, or water use of a representative sample of covered products that minimally comply with the existing standard. (42 U.S.C. 6293(e)(2)) Although DOE remains obligated under 42 U.S.C. 6293(e)(1) to conduct an analysis of the impact of the test procedure amendments, amendments to the existing energy conservation standards are not required, because the statute already explicitly provides that the test procedure amendments for standby mode and off mode shall not apply to the energy conservation standards currently in place. The following discussion assesses these anticipated impacts, as well as the pathway for regulated entities to continue to be able to ascertain, certify, and report compliance with the existing standards until such time as amended standards are established which comprehensively address standby mode and off mode energy consumption.

    For dishwashers, the current energy conservation standards (10 CFR 430.32(f)) are based on EAEU, which includes a simplified measure of standby mode power consumption. Because today's proposed amendments would revise the calculations for EAEU and EAOC, both of which currently incorporate standby mode power, DOE investigated how the proposed amendments would affect the measured efficiency. As discussed in section III.G, DOE has tentatively determined that the proposed amendments in today's NOPR would not measurably alter the measured efficiency of dishwashers. In addition, the proposed amendments would clarify that the amended calculations for EAEU need not be performed to demonstrate compliance with the existing energy conservation standards until the compliance date of amended energy conservation standards for dishwashers which take into account standby mode and off mode energy use. The proposed amendments would also require that any representations as to standby mode and off mode energy use must use the amended calculations for EAEU and EAOC on or after a date 180 days after publication of the test procedure final rule. The amended test procedure, therefore, would still be able to be used by manufacturers to certify compliance of existing dishwashers with the current energy conservation standards.

    The current Federal energy conservation standards for dehumidifiers (10 CFR 430.32(v)), which are based on EF, do not currently account for standby mode or off mode power consumption. DOE proposes to establish a new integrated efficiency metric (integrated annual energy use) to account for standby mode and off mode power consumption. For this reason, the proposed amended test procedure would not alter the existing energy efficiency descriptor and, therefore, would not affect a manufacturer's ability to demonstrate compliance with previously established standards for dehumidifiers.

    As noted earlier, the current energy conservation standards for cooking products (10 CFR 430.32(j)) require only that gas cooking products with an electrical supply cord not be equipped with a constant-burning pilot light. The same requirement applies to gas cooking products without an electrical supply cord, beginning on April 9, 2012. There are currently no performance-based Federal energy conservation standards for conventional cooking products (including energy use in standby mode and off mode). Thus, given the design standard currently in place, the proposed test procedure amendments would not alter one's ability to comply with the existing energy conservation standard for cooking products.

    These amended test procedures would become effective in terms of adoption into the CFR, 30 days after the test procedure final rule is published in theFederal Register. However, DOE is proposing added language to the regulations codified in the CFR that would state that any added procedures and calculations for standby mode and off mode energy consumption resulting from implementation of the relevant provisions of EISA 2007 need not be performed at this time to determine compliance with the current energy conservation standards. Subsequently, manufacturers would be required to usethe amended test procedures' standby mode and off mode provisions to demonstrate compliance with DOE's energy conservation standards on the mandatory compliance date of a final rule establishing amended energy conservation standards for dishwasher, dehumidifier, and conventional cooking products that address standby mode and off mode energy consumption, at which time the limiting statements in the DOE test procedures would be removed. Further clarification would also be provided that as of 180 days after publication of a test procedure final rule, any representations related to the standby mode and off mode energy consumption of these products must be based upon results generated under the applicable provision of these test procedures. (42 U.S.C. 6293(c)(2))

    As noted above, pursuant to its statutory mandate under 42 U.S.C. 6295(gg)(2), DOE is only addressing issues related to standby mode and off mode energy use in the current test procedure rulemaking for residential dishwashers, dehumidifiers, and conventional cooking products. For issues that are determined to relate to active mode energy use for any of these products, DOE will consider such amendments in a future test procedure rulemaking under section 302 of EISA 2007. Specifically, under that provision, DOE is required to review test procedures for covered products not later than every 7 years and to determine whether the test procedures accurately and fully comply with the requirement that they produce test results which are representative and not unduly burdensome to conduct. (42 U.S.C. 6293(b)(1))

    III. Discussion A. Products Covered by the Proposed Test Procedure Amendments

    Today's proposed amendments to the DOE test procedures cover dishwashers, which DOE defines as follows:

    Dishwashermeans a cabinet-like appliance which with the aid of water and detergent, washes, rinses, and dries (when a drying process is included) dishware, glassware, eating utensils, and most cooking utensils by chemical, mechanical and/or electrical means and discharges to the plumbing drainage system.” 10 CFR 430.2.

    Today's proposed amendments to the DOE test procedures also cover dehumidifiers, which DOE defines as follows:

    Dehumidifiermeans a self-contained, electrically operated, and mechanically refrigerated encased assembly consisting of—

    (1) A refrigerated surface (evaporator) that condenses moisture from the atmosphere;

    (2) A refrigerating system, including an electric motor;

    (3) An air-circulating fan; and

    (4) Means for collecting or disposing of the condensate.”

    Id.

    Today's proposed amendments to the DOE test procedures also cover cooking products, specifically conventional cooking products, which are defined as:

    Cooking productsmeans consumer products that are used as the major household cooking appliances. They are designed to cook or heat different types of food by one or more of the following sources of heat: Gas, electricity, or microwave energy. Each product may consist of a horizontal cooking top containing one or more surface units and/or one or more heating compartments. They must be one of the following classes: Conventional ranges, conventional cooking tops, conventional ovens, microwave ovens, microwave/conventional ranges and other cooking products.”

    Conventional cooking topmeans a class of kitchen ranges and ovens which is a household cooking appliance consisting of a horizontal surface containing one or more surface units which include either a gas flame or electric resistance heating.”

    Conventional ovenmeans a class of kitchen ranges and ovens which is a household cooking appliance consisting of one or more compartments intended for the cooking or heating of food by means of either a gas flame or electric resistance heating. It does not include portable or countertop ovens which use electric resistance heating for the cooking or heating of food and are designed for an electrical supply of approximately 120 volts.”

    Conventional rangemeans a class of kitchen ranges and ovens which is a household cooking appliance consisting of a conventional cooking top and one or more conventional ovens.”

    Id.

    DOE is not proposing any amendments to these definitions in today's notice.

    B. Incorporation by Reference of IEC Standard 62301 (First Edition) for Measuring Standby Mode and Off Mode Power Consumption

    As required by EPCA, as amended by EISA 2007, DOE considered the most current versions of IEC Standard 62301 and IEC Standard 62087 for measuring power consumption in standby mode and off mode when developing today's proposed amendments to the test procedures. (42 U.S.C. 6295(gg)(2)(A)) DOE notes that IEC Standard 62301 includes provisions for measuring standby power in electrical appliances, and, thus, is relevant to this rulemaking. 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 methods for measuring the power consumption of electrical appliances such as dishwashers, dehumidifiers, or conventional cooking products. Therefore, DOE has tentatively determined that IEC Standard 62087 is unsuitable to this rulemaking and has not included any of its provisions in today's proposed test procedure amendments.

    DOE proposes to incorporate by reference into these test procedures specific clauses from IEC Standard 62301 (First Edition) for measuring standby mode and off mode power. Specifically, two clauses provide test conditions and test procedures for measuring the average standby mode and average off mode power consumption. Section 4 of IEC Standard 62301 (First Edition) specifies test room conditions, supply voltage waveform, and power measurement meter tolerances, thereby ensuring repeatable and precise measurements of standby mode and off mode power consumption. Section 5 of IEC Standard 62301 (First Edition), regarding test procedures, specifies methods for measuring power consumption when it is stable and unstable (i.e.,varies over a representative cycle).

    Specifically, DOE proposes to incorporate by reference into the DOE test procedures for dishwashers, dehumidifiers, and conventional cooking products the following provisions from IEC Standard 62301 (First Edition):

    Table I.2—Provisions From IEC Standard 62301 (First Edition) Proposed to be Incorporated by Reference Section Paragraph 4. General conditions for measurements 4.2Test room.
  • 4.4Supply voltage waveform.
  • 4.5Power measurement accuracy.
  • 5. Measurements 5.1General, Note 1.
  • 5.2Selection and preparation of appliance or equipment.
  • 5.3Procedure.
  • DOE notes that the current dishwasher test procedure already includes testing methods for measuring standby power consumption that are very similar to the provisions in IEC Standard 62301 (First Edition). However, DOE also notes that the current dishwasher test procedure does not contain provisions for measuring multiple standby modes or an off mode. EPCA, as amended by EISA 2007, requires DOE to amend its test procedures for all covered products to fully account for and incorporate standby mode and off mode energy consumption, and to consider the most current version of IEC Standard 62301 as it does so. (42 U.S.C. 6295(gg)(2)(A)) As discussed below, DOE proposes to amend the dishwasher test procedure to include new definitions of “standby mode,” “off mode,” and “active mode” based on the provisions in IEC Standard 62301 (FDIS). DOE also analyzed the current DOE dishwasher test procedure to determine if any other amendments would be necessary. The analysis has led DOE to tentatively conclude that the proposed clauses from IEC Standard 62301 (First Edition) presented earlier would clarify the dishwasher testing procedure, as well as produce representative and repeatable test results.

    As discussed in Section I, the current DOE conventional cooking products test procedure does not fully account for standby mode and off mode energy consumption. The test procedure accounts only for the annual energy consumption of a continuously-operating clock, and the standby energy use associated with a continuously-burning pilot light for gas cooking products. Otherwise, this test procedure does not address energy use in standby mode or off mode. For this reason, DOE has tentatively concluded that adopting the clauses from IEC Standard 62301 (First Edition) as proposed would provide for a test procedure that would produce representative and repeatable test results that would fully account for standby mode and off mode energy consumption.

    As also discussed in section I, the current DOE dehumidifier test procedure does not contain any provisions for measuring energy use in standby mode or off mode. DOE has tentatively concluded that adopting the clauses from IEC Standard 62301 (First Edition) as proposed would provide for a test procedure that would produce representative and repeatable test results that would fully account for the standby mode and off mode energy consumption of dehumidifiers.

    DOE invites comment on whether IEC Standard 62301 (First Edition) can adequately measure standby mode and off mode power consumption for dishwashers, dehumidifiers, and conventional cooking products, and whether these specific provisions should be incorporated into the test procedures.

    DOE is aware that the EPCA requirement to consider IEC Standard 62301 in developing amended test procedures to include standby mode and off mode power consumption results in a potential conflict between the EPCA and IEC Standard 62301 (FDIS) definitions of “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)) However, paragraph 3.1 of the IEC Standard 62301 (First Edition) 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.” Finally, DOE adopted a third definition prior to EISA 2007 for “standby mode” nearly identical to that of IEC Standard 62301 (First Edition) 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 the dishwasher 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) However, DOE is free to resolve any such conflict, because EISA 2007 specifically grants authority to amend the statutory definitions of “active mode,” “off mode,” and “standby mode.” (42 U.S.C. 6295(gg)(1)(B)) DOE notes that the statute requires consideration of the most current version of IEC Standard 62301, but it does not require its adoption if DOE determines that another definition(s) would be more appropriate.

    Although 42 U.S.C. 6295(gg)(2)(A) requires that DOE consider the most current version of IEC Standard 62301, DOE notes that 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 mode,” and “disconnected mode,” and it would also revise the current IEC Standard 62301 (First Edition) definition of “standby mode.” However, the IEC anticipates that the final version of IEC Standard 62301 (Second Edition) will likely be published only in late 2010 at the earliest. Therefore, for this proposed rule, the second edition is not available for DOE's consideration or incorporation by reference. Thus, IEC Standard 62301 (First Edition) is the “current version” for purposes of 42 U.S.C. 6295(gg)(2)(A).

    DOE is aware that there are significant differences between IEC Standard 62301 (First Edition) and IEC Standard 62301 (FDIS), which is the latest draft version of IEC Standard 62301 (Second Edition). For example, IEC Standard 62301 (FDIS) clarifies certain provisions, such as clarifying the definition of “standby mode” and “off mode” to allow for the measurement of multiple standby power modes.

    DOE has reviewed IEC Standard 62301 (FDIS) and anticipates that, once finalized, it will ultimately define thevarious modes differently than IEC Standard 62301 (First Edition). IEC Standard 62301 (FDIS) incorporates responses to comments from multiple national committees from member countries on several previous draft versions, and thus, DOE believes, it provides the best available mode definitions. Although the revised IEC Standard 62301 (Second Edition) has not yet been officially released, DOE has decided to consider the substance of the new operational mode definitions from the draft version IEC Standard 62301 (FDIS). DOE notes that the mode definitions in IEC Standard 62301 (FDIS) are substantively similar to those in the previous draft version (IEC Standard 62301 (CDV)), which were the subject of extensive comments from interested parties during recent DOE test procedure rulemakings addressing standby mode and off mode energy use in other products (i.e.,microwave ovens, clothes dryers, and room air conditioners). In those instances, interested parties indicated general support for adopting the mode definitions provided in IEC Standard 62301 (CDV). Due to the effective equivalence of the mode definitions in IEC Standard 62301 (CDV) and IEC Standard 62301 (FDIS), DOE believes the public comment support expressed for the mode definitions in IEC Standard 62301 (CDV) would extend to those in IEC Standard 62301 (FDIS).

    DOE notes that other significant changes in the methodology were first introduced only at the IEC Standard 62301 (FDIS) stage. These changes have not been the subject of significant public comment from interested parties, nor has DOE had the opportunity to conduct a thorough analysis of those provisions. Consequently, the merits of these latest changes have not been fully vetted, as would demonstrate that they are preferable to the existing methodological provisions in the current version of the IEC standard. Thus, DOE is not able to determine whether the updated methodology represents the best available means to measure standby mode and off mode energy use, so DOE has tentatively decided to base the proposed test procedure amendments (other than the mode definitions previously discussed) on the provisions of IEC Standard 62301 (First Edition).

    After considering the most current version of IEC Standard 62301 (i.e.,the First Edition) and the draft version of IEC Standard 62301 (i.e.,FDIS), DOE has tentatively concluded that the definitions of “standby mode,” “off mode,” and “active mode” provided in IEC Standard 62301 (FDIS) are the most useful, in that they expand upon the EPCA mode definitions and provide additional guidance as to which functions are associated with each mode. Therefore, DOE is proposing definitions of “standby mode,” “off mode,” and “active mode” based on the definitions provided in IEC Standard 62301 (FDIS). These definitions are discussed in detail immediately below in section III.C.

    C. Determination and Classification of Operational Modes

    As stated earlier, without further clarification, regulated parties' attempts to reconcile differences between the mode definitions specified by EPCA and IEC Standard 62301 (First Edition) could lead to multiple interpretations. Therefore, DOE is proposing regulatory definitions for these key terms in order to ensure consistent application of the test procedure provisions related to standby mode and off mode. This section first discusses these overarching definitional changes and then follows with a product-specific analysis of different operational modes in order to determine whether they are active mode, standby mode, or off mode functions. DOE's proposed approach is set forth below.

    EPCA defines “active mode” as the condition in which an energy-using product:

    (1) Is connected to a main power source;

    (2) Has been activated; and

    (3) Provides one 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:

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

    (2) Offers one or more of the following user-oriented or protective functions:

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

    (b) Continuous functions, including information or status displays (including clocks) or sensor-based functions.

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

    This definition of “standby mode” differs from the one provided in IEC Standard 62301 (First Edition) by permitting the inclusion of multiple standby modes.

    EPCA defines “off mode” as the condition in which an energy-using product:

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

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

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

    DOE recognizes that the EPCA definitions for “active mode,” “standby mode,” and “off mode” were developed to be broadly applicable for many energy-using products. For specific products with multiple functions, these broad definitions could lead to multiple interpretations. Therefore, DOE proposes to amend the test procedures to include definitions for these modes based on the definitions provided in IEC Standard 62301 (FDIS), with added provisions specific to dishwashers, dehumidifiers, and conventional cooking products. DOE's proposed approach is discussed below.

    DOE proposes to define “active mode” for dishwashers, dehumidifiers, and conventional cooking products as the condition in which the energy-using product is connected to a mains power source, has been activated, and provides one or more main functions. DOE notes that section 3.8 of IEC Standard 62301 (Second Edition Committee Draft 2) (IEC Standard 62301 (CD2)) provides the additional clarification that “delay start mode is a one off user initiated short duration function that is associated with an active mode.” The subsequent IEC Standard 62301 Committee Draft for Vote (IEC Standard 62301 (CDV)) removed this clarification based on a comment from a member committee on IEC Standard 62301 (CD2) that the clarification conflicted with the proposed definition of “standby mode,” which would include “activation of * * * active mode by * * * timer.” However, in its response to that comment, the IEC reiterated that delay start mode is a one-off function of limited duration, even though it took action to delete the clarification in IEC Standard 62301 (CDV).9 DOE infers this to mean that delay start mode should, therefore, be considered part of active mode. However, DOE notes that IEC Standard 62301 (FDIS) classifies delay start as a secondary function and not part of active mode. DOE continues to believe, however, that because delay start is of limited duration and is uniquely associated with the initiation of a main function, it should be considered part of active mode. Additional discussion of delay start mode is provided later in this section.

    9Compilation of comments on 59/523/CD: IEC 62301 Ed 2.0 “Household electrical appliances—Measurement of standby power” (August 7, 2009) p. 6. IEC Standards are available online athttp://www.iec.ch.

    DOE also proposes the following clarifications for the range of mainfunctions that would be classified as active mode for each product:

    Dishwashers—“Active mode” means a mode in which the dishwasher is performing the main function of washing, rinsing, or drying (when a drying process is included) dishware, glassware, eating utensils, and most cooking utensils by chemical, mechanical and/or electrical means, or is involved in functions necessary for these main functions, such as admitting water into the dishwasher or pumping water out of the dishwasher.

    Conventional Cooking Products—“Active mode” means a mode in which a conventional cooking top, conventional oven, or conventional range is performing the main function of cooking, heating, proofing, or holding the cooking load by means of either a gas flame or electric resistance heating.

    Dehumidifiers—“Active mode” means a mode in which a dehumidifier is performing the main functions of removing moisture from ambient air by drawing moist air over a refrigerated coil using a fan, circulating air through activation of the fan without activation of the refrigeration system, or defrosting the refrigerant coil.

    DOE proposes to define “standby mode” for dishwashers, dehumidifiers, and conventional cooking products as any mode in which the product is connected to a mains power source and offers one or more of the following user-oriented or protective functions which may persist for an indefinite time:10

    10The actual language for the “standby mode” definition in IEC Standard 62301 (FDIS) describes “* * * user oriented or protective functions which usually persist” rather than “* * * user oriented or protective functions which may persist for an indefinite time.” DOE notes, however, that section 5.1 of IEC Standard 62301 (FDIS) states that “a mode is considered to be persistent where the power level is constant or where there are several power levels that occur in a regular sequence for an indefinite period of time.” DOE believes that the proposed language, which was originally included in IEC Standard 62301 (CD2), encompasses the possible scenarios foreseen by section 5.1 of IEC Standard 62301 (FDIS) without unnecessary specificity.

    • To facilitate the activation of other modes (including activation or deactivation of active mode) by remote switch (including remote control), internal sensor, or timer;

    • Continuous functions, including information or status displays (including clocks) or sensor-based functions.

    DOE proposes the additional clarification that a timer is a continuous clock function (which may or may not be associated with a display) that provides regular scheduled tasks (e.g.,switching) and that operates on a continuous basis. As noted in section III.B, this definition of “standby mode” is based on the definitions provided in IEC Standard 62301 (FDIS), and expands upon the EPCA mode definitions to provide additional clarifications as to which functions are associated with each mode.

    As noted earlier, the current DOE dishwasher test procedure defines “standby mode” as the lowest power consumption mode that cannot be switched off or influenced by the user and that may persist for an indefinite time when the dishwasher is connected to the main electricity supply and used in accordance with manufacturer's instructions. That definition is comparable to the definition in IEC Standard 62301 (First Edition). DOE believes that the proposed “standby mode” definition based on IEC Standard 62301 (FDIS) is preferable in that it expands upon the definition in IEC Standard 62301 (First Edition) and provides additional guidance as to what functions are associated with standby mode. For this reason, DOE proposes in today's NOPR to amend the “standby mode” definition in the dishwasher test procedure based on the definition provided in IEC Standard 62301 (FDIS). Furthermore, DOE proposes to redesignate the current DOE definition as a “simplified standby mode” in order to allow manufacturers to continue to use the existing standby mode provisions to determine compliance with the current dishwasher energy conservation standards until such time as these standards are amended to address standby mode and off mode energy use.

    DOE proposes to define “inactive mode” for dishwashers, dehumidifiers, and conventional cooking products as a standby mode that facilitates the activation of active mode by remote switch (including remote control), internal sensor, or timer, or that provides continuous status display.

    The following discussion analyzes various product-specific modes for dishwashers, dehumidifiers, and conventional cooking products to determine whether they would be properly characterized as active mode, standby mode, or off mode functions.

    1. Dishwashers

    DOE is aware of two additional relevant modes for dishwashers: (1) delay start mode; and (2) cycle finished mode. “Delay start mode” is defined as a mode in which activation of an active mode is facilitated by a timer. “Cycle finished mode” is defined as a mode that provides continuous status display following operation in active mode. As discussed earlier, because delay start mode is not a mode that may persist for an indefinite time, DOE believes that delay start mode would not be considered part of standby mode, but instead would be a form of active mode. DOE is not proposing amendments to the dishwasher test procedure to define “delay start mode” or to measure power consumption in this mode. DOE may consider amendments addressing delay start mode issues in a future dishwasher test procedure rulemaking conducted under the 7-year schedule requirements of the EISA 2007 amendments to EPCA. (42 U.S.C. 6293(b)(1))

    Based on the proposed “standby mode” definition, cycle finished mode, a mode that provides a continuous status display and may persist for an indefinite time, would be considered as part of a standby mode. Therefore, DOE proposes in today's NOPR to define cycle finished mode for dishwashers as “a mode which provides continuous status display following operation in active mode.” Proposed provisions to measure energy use in delay start mode and cycle finished mode are discussed in section III.E.1.

    2. Dehumidifiers

    DOE is aware of three additional relevant modes for dehumidifiers: (1) Delay start mode; (2) off-cycle mode; and (3) bucket full/removed mode. The definition for “delay start mode” for dehumidifiers is the same as that for dishwashers. “Off-cycle mode” is defined as a mode in which a dehumidifier has cycled off its main function by humidistat or humidity sensor, does not have its fan or blower operating, and will reactivate the main function according to the humidistat or humidity sensor signal. “Bucket full/removed mode” is defined as a mode in which the dehumidifier has automatically powered off its main function by detecting when the water collection bucket is full or has been removed. For the same reasons discussed earlier for dishwashers, DOE believes that delay start mode would not be considered a standby mode, but instead would be a form of active mode. Therefore, DOE is not proposing amendments to define or to measure power consumption in “delay start mode.” DOE may consider amendments addressing delay start mode issues in a future dehumidifier test procedure rulemaking conducted under the 7-year schedule requirements of the EISA 2007 amendments to EPCA. (42 U.S.C. 6293(b)(1))

    DOE believes that off-cycle mode and bucket full/removed mode are modes that may persist for an indefinite time and, under the proposed definition, would be considered as part of standby mode. Therefore, DOE proposes amending its dehumidifier test procedure to include definitions of “off-cycle mode” and “bucket full/removed mode.” Proposed provisions to measure energy use in delay start mode, off-cycle mode, and bucket full/removed mode are discussed in section III.E.2.

    3. Conventional Cooking Products

    DOE is aware of three additional relevant modes for c
