AGENCY:

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

ACTION:

Notice of proposed rulemaking and 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 furnaces and boilers to provide for measurement of standby mode and off mode energy consumption. Specifically, the proposed amendments would incorporate into the DOE test procedures 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 this standard for measuring standby mode and off mode power consumption in furnaces and boilers. In addition, the proposed amendments would add new calculations to determine annual energy consumption associated with 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 of Start Printed Page 36960these products. DOE is also announcing a public meeting to discuss and receive comments on the issues presented in this notice.

VI. Approval of the Office of the Secretary

I. Background and Authority

Title III of the Energy Policy and Conservation Act (42 U.S.C. 6291 et seq.; EPCA or 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 residential furnaces and boilers (all of which are referenced below as “covered products”).[1] (42 U.S.C. 6291(1)-(2) and 6292(a)(5))

Under the Act, this program consists essentially of three parts: (1) Testing; (2) labeling; and (3) establishing Federal energy conservation standards. The testing requirements consist of test procedures that manufacturers 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 representing the efficiency of those products. Similarly, DOE must use these test procedures to Start Printed Page 36961determine whether the products comply with standards adopted under EPCA. 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 on them, with a comment period no less than 60 or more than 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))

On December 19, 2007, the Energy Independence and Security Act of 2007 (EISA 2007), Public Law 110-140, was enacted. The EISA 2007 amendments to EPCA, in relevant part, require DOE to amend the test procedures for all covered products to include measures of standby mode and off mode energy consumption. Specifically, section 310 of EISA 2007 provides definitions of “standby mode” and “off mode” (42 U.S.C. 6295(gg)(1)(A)); however, the statute permits DOE to amend these definitions in the context of a given product (42 U.S.C. 6295(gg)(1)(B)). The legislation requires integration of such energy consumption “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 and incorporate the standby 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.” (42 U.S.C. 6295(gg)(2)(A)).

Under the statutory provisions introduced by EISA 2007, any such amendment must consider the most current versions of International Electrotechnical Commission (IEC) Standard 62301, Household electrical appliances—Measurement of standby power, (First Edition 2005-06) and IEC Standard 62087, Methods of measurement for the power consumption of audio, video, and related equipment (Second Edition, 2008-09).[2] Id. For residential furnaces and boilers, DOE must prescribe any such amendment to the test procedures by September 30, 2009. (42 U.S.C. 6295(gg)(2)(B)(iv))

DOE's current test procedure for residential furnaces and boilers is found at 10 CFR part 430, subpart B, appendix N, Uniform Test Method for Measuring the Energy Consumption of Furnaces and Boilers. DOE established its test procedures for furnaces and boilers in a final rule published in the Federal Register on May 12, 1997. 62 FR 26140. This procedure establishes a means for determining annual energy efficiency and annual energy consumption of gas-fired, oil-fired, and electric furnaces and boilers. It is important to note that gas-fired and oil-fired furnaces and boilers consume both fossil fuel and electricity. Electric furnaces and boilers only consume electricity. In this test procedure, fossil-fuel energy consumption is accounted for comprehensively over a full-year cycle, thereby satisfying EISA 2007 requirements for fossil-fuel standby mode and off mode energy consumption. However, electrical energy consumption in standby mode and off mode is not accounted for in the current test procedures.

II. Summary of the Proposed Rule

First, today's NOPR tentatively concludes that, for gas-fired and oil-fired furnaces and boilers, the current test procedures already fully account for and incorporate the standby mode and off mode fossil-fuel energy consumption. (42 U.S.C. 6295(gg)(2)(A)(i))

Second, since standby mode and off mode electrical energy consumption are not included in the existing test procedures, today's NOPR proposes to amend the test procedures for residential furnaces and boilers to address the statutory requirement to incorporate standby mode and off mode electrical energy consumption. Specifically, measurement procedures would be added, and annual energy consumption equations would be expanded to include standby mode and off mode electrical energy use. In addition, it is noted that one applicable energy efficiency descriptor (i.e., Energy Factor) would automatically reflect incorporation of standby mode and off mode energy use, without the need for specific amendment.

In amending the current test procedures, DOE proposes to incorporate by reference IEC Standard 62301, Household electrical appliances—Measurement of standby power (First edition, 2005-06), regarding test conditions and testing procedures for measuring the average standby and off mode power.[3] DOE also proposes to incorporate into the test procedure clarifying definitions of “active mode,” “standby mode,” and “off mode” that are specific to furnaces and boilers but consistent with definitions for those terms set forth in the EISA 2007 amendments to EPCA. Further, DOE proposes to include in the test procedures additional language that would clarify the application of IEC Standard 62301 for measuring standby mode and off mode power consumption. (42 U.S.C. 6295(gg)(1)(A))

The EISA 2007 amendments to EPCA direct DOE to amend the furnace and boiler test procedures to integrate standby mode and off mode energy consumption into the overall energy efficiency, energy consumption, or other energy descriptor for these products, if technically feasible. If that is not technically feasible, DOE must instead prescribe a separate standby mode and off mode energy use test procedure, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)) [4] DOE believes that it is technically feasible to integrate standby mode and off mode energy consumption into the descriptors found in the existing furnace and boiler test procedures. Accordingly, today's Start Printed Page 36962proposal would integrate standby mode and off mode energy consumption into the test procedures' overall annual energy consumption equations. However, it is important to note that DOE is not proposing amendments to the current regulating quotient specified under EPCA, Annual Fuel Utilization Efficiency (AFUE), because that metric currently accounts for fossil fuel energy consumption in standby mode and off mode but is not suitable for measurement of electrical energy consumption in those modes. (42 U.S.C. 6291(22)) A full discussion of the reasoning for not fully integrating standby and off mode energy into the current regulating quotient, AFUE, is provided in section III.F below.

EPCA provides that amendments to the test procedures that include standby mode and off mode energy consumption will not be used to determine compliance with previously established standards. (See 42 U.S.C. 6295(gg)(2)(C).) Furthermore, EPCA requires DOE to determine whether a proposed test procedure amendment would alter the measured efficiency of a product, and require adjusting existing standards. (42 U.S.C. 6293(e)) However, the current Federal energy conservation standards for furnaces and boilers utilize an energy efficiency descriptor that would be unaffected by the inclusion of new provisions in the test procedures meeting the requirements of EISA 2007 and pertaining to standby mode and off mode energy consumption. Therefore, today's notice would not affect a manufacturer's ability to demonstrate compliance with previously established standards.

These amended test procedures would become effective 30 days after the date of publication in the Federal Register of the 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 electrical standby mode and off mode energy consumption need not be performed to determine compliance with the current energy conservation standards for residential furnaces and boilers, because the current energy conservation standards do not account for electrical standby mode and off mode power consumption. Instead, manufacturers would be required to use the test procedures' electrical standby mode and off mode provisions to demonstrate compliance with DOE's energy conservation standards on the compliance date of any final rule establishing amended energy conservation standards for these products that address standby mode and off mode power consumption.

III. Discussion

A. EISA 2007 as Applied to Residential Furnaces and Boilers

As a first step in addressing the requirements of EISA 2007, the relevant terms and concepts from that statute need clarification as they apply to residential furnaces and boilers. While EISA 2007 provided definitions and concepts that are generally applicable and workable within the context of the existing furnace and boiler test procedure, some clarifying language is necessary to address the specific characteristics of the products relevant to this rulemaking. The following paragraphs discuss these proposed clarifications.

Section 310(3) of EISA 2007 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)) This statutory definition of “active mode” is comparable to what is referred to as “on-cycle” in the current residential furnaces and boilers test procedures. (ANSI/ASHRAE Standard 103-1993, Method of Testing for Annual Fuel Utilization Efficiency of Residential Central Furnaces and Boilers) On-cycle is the period during the heating season when the furnace or boiler is performing its main function (i.e., heat delivery). The heat delivery process begins with the activation of the burner or electric resistance heating element followed by, or simultaneous with, the activation of circulating fans or pumps, and ends with the deactivation of these components. As discussed in section III.G below, the duration of on-cycle can be estimated in the test procedure as burner operating hours (BOH).

In light of the above, DOE is proposing to add a definition of “active mode” in the furnace and boiler test procedure. See section 2.6 of Appendix N to subpart B of part 430.

Section 310(3) of EISA 2007 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)) The statutory definition of “standby mode” is comparable to what is referred to as “off-cycle” in the current residential furnace and boiler test procedure. The duration of off-cycle would be the total time during the heating season when the furnace or boiler is connected to power sources and not in active mode.

In light of the above, DOE is proposing to add a definition of “standby mode” in the furnace and boiler test procedure. See section 2.7 of Appendix N to subpart B of part 430.

Section 310(3) of EISA 2007 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 or active mode function.” (42 U.S.C. 6295(gg)(1)(A)(ii)) For residential furnaces and boilers, off mode would be periods during the non-heating season where the furnace or boiler is connected to power sources but is not activated to provide heat. This period is called non-heating season in the test procedures.

In light of the above, DOE is proposing to add a definition of “off mode” in the furnace and boiler test procedure: See section 2.8 of Appendix N to subpart B of part 430.

DOE believes these proposed definitions provide the clarification necessary to carry out the requirements of EISA 2007 without unduly complicating matters by addressing possible inaccuracies such as those that might be caused by slight differences in run times for burners and air circulating fans. DOE requests comments on this approach for characterizing active, standby, and off mode operation of residential furnaces and boilers.

B. Gas and Oil Energy Consumption in the Furnace and Boiler Test Procedures

DOE is tentatively concluding that the existing test procedures for residential furnaces and boilers already fully account for and integrate standby mode and off mode fossil fuel energy consumption for gas-fired and oil-fired furnaces and boilers. Underlying the basis for this conclusion is the manner in which fossil fuel is accounted for in two of the test procedure's three annual efficiency metrics (i.e., heating seasonal efficiency and AFUE). The third annual efficiency metric (Energy Factor), as mentioned above, has an accounting of electrical energy consumption for gas-fired and oil-fired furnaces and boilers and will be discussed in detail in proceeding sections of this document.

The existing test procedure for gas-fired and oil-fired furnaces and boilers specifies a flue loss test that is augmented by calculations of jacket loss Start Printed Page 36963and latent heat loss. Accordingly, the test procedure requires measurement of temperatures and percent concentration of carbon dioxide (CO2) in the flue. CO2 measurements are used to infer how complete the combustion process is and how much excess air is passing through the appliance and into the flue. Temperature measurements are used to infer the value of the heat energy in this air flow through the flue. The product's fossil fuel and electric input is measured within a tolerance of the nameplate input.[5] As specified in the ASHRAE 103-1993, temperature and CO2 measurements are taken during a sequencing of three standardized tests: (1) Steady-state; (2) cool-down; (3) and heat-up. These tests generally represent the cycling encountered when the furnace or boiler is in operation. The result is a uniform set of temperature and CO2 measurements which can be used to capture the thermal performance of the tested unit. From this relatively limited set of test data, on-cycle and off-cycle losses are determined using integration coefficients and a complete suite of calculations that address various installations and design features. Additional testing and calculation may apply to some furnaces and boilers with certain design features (e.g., condensate collection for condensing units, and direct measurement of draft coefficients for units that restrict combustion side air flow during the off cycle).

The on-cycle and off-cycle losses, along with jacket loss and latent heat loss, are all expressed as a percentage loss relative to the input energy.

The resulting general format for the heating seasonal efficiency is as follows:

Effyhs = 100 − LL,A − Lj − Ls, on − Ls,off − Li, on − Li,off

where:

LL,A = average latent heat loss of the fuel

Lj = jacket heat loss

Ls,on = on-cycle sensible heat loss [6]

Ls,off = off-cycle sensible heat loss

Li,on = on-cycle infiltration loss [7]

Li,off = off-cycle infiltration loss

The test procedure's on-cycle and off-cycle are essentially identical in meaning to EISA 2007's “active mode” and “standby mode,” respectively. There are some minor differences, resulting from the nature of a flue loss methodology. For example, the Ls,off is the quantification of the sensible heat loss occurring during the off-cycle, not the energy input consumed during the off-cycle, which would more closely track the EISA 2007 “standby mode” definition. Nonetheless, the test procedure's on-cycle/off-cycle format, coupled with the clarifying definitions of “active mode” and “standby mode,” provides a complete accounting of fossil fuel energy loss during the entire heating season. In EISA 2007 terminology, both active and standby modes of fossil fuel consumption are fully accounted for and integrated into the Heating Seasonal Efficiency descriptor.

A second efficiency descriptor, AFUE, includes an accounting of the non-heating season fossil fuel energy consumption (i.e., pilot light non-heating energy consumption). Non-heating season directly relates to the EISA 2007 definition of “off mode.” Accordingly, AFUE provides a full accounting of fossil fuel off mode energy consumption pursuant to EISA 2007.

In addition to the efficiency descriptors discussed above, the test procedure's annual energy consumption calculations also represent a complete accounting of fossil fuel consumption.

In sum, the energy consumption equations in the existing test procedures are an entire year's accounting of fossil fuel consumption (i.e., 8,760 hours), which includes active, standby, and off mode energy consumption, as envisioned under EISA 2007.[8] Given that EISA 2007 does not prescribe any time periods over which to measure the energy consumption for all three modes, DOE believes it is reasonable to interpret the Act as permitting the consolidation of active, standby, and off modes together into an entire year's accounting.

In consideration of all of the above, and pursuant to section 310(2)(A)(i) of EISA 2007, DOE has tentatively concluded that the existing test procedures for residential furnaces and boilers already fully account for and integrate standby mode and off mode fossil-fuel energy consumption.

C. Electrical Energy Accounting in the Existing Test Procedures for Gas-Fired and Oil-Fired Furnaces and Boilers

The treatment of electricity consumption in the test procedures for residential gas-fired and oil-fired furnaces and boilers begins with the measurement of full-load wattages of major electrical components, referred to as “auxiliaries” in that document. These measurements are termed “PE” and “BE” in the test procedures. “PE” is the electric power to the power burner, and “BE” is the electrical power to the conditioned air blower for furnaces, or, electrical power to the circulating pump for boilers. A separate measure of power to the interrupted ignition device, “PEIG,” is required if such device is present. These wattage values are used in calculations of annual energy consumption of electricity.

Estimation of annual electricity consumption from full-load wattages involves a complicated set of equations that estimate the expected annual hours of use or run hours for the electric auxiliaries. In performing such calculation, the test procedure begins with an estimate of the average burner operating hours that would be required to meet a representative annual heating demand. Generally, the auxiliary run hours would equal burner operating hours if there were no time delays or overruns for the auxiliaries. The test procedure requires measurement or assignment of time delays and overruns. The resulting proportioning of auxiliaries runtime to burner runtime is used to provide an estimate of annual electrical power consumption. For example, if a blower runs 10 percent more than the burner, the annual hours of blower runtime is 1.1 times the burner operating hours. The product of the blower runtime ratio, burner operating hours, and the measured wattage results in an estimate of annual electrical energy consumption for the blower.

A complicating factor is the heating effect provided by the electrical auxiliaries. Explaining further, if some of the heat produced by the electric auxiliaries is deemed useful heat to the house, this heat energy is credited in the burner operating hours calculation as useful heat. In performing such calculation, the test procedure first establishes which auxiliaries provide useful heat. For example, the blower fan on a forced air furnace is credited fully as useful heat. For indoor installed units, induced draft and forced draft fans are partially credited (differently) based on the efficiency of the motor.[9] The partial credit relates to the determination of whether the heat caused by the electric motor inefficiencies contributes to heating a space. For units installed in isolated combustion systems, no useful heat is Start Printed Page 36964ascribed to induced draft or forced draft fans. After these determinations and assignments, the test procedure calculates the adjusted burner operating hours that reflect the offset of heating load attributed to the useful heating effect of the electrical auxiliaries.

The annual fuel consumption, “EF,” which is adjusted for electrical heat offset, and annual auxiliary electrical energy consumption, “EAE,” are then used to calculate annual operating cost. Additionally, EF and EAE are used in an energy efficiency descriptor, Energy Factor (EF). Energy Factor is the ratio of useful output provided by the fossil fuel to the total site energy consumption.

This characterization of the electric auxiliaries for gas-fired and oil-fired furnaces and boilers is best described in EISA 2007 terminology as “active mode.” The accounting done in the existing test procedures only reflects the “on” period of the electric auxiliaries. There is no measurement or accounting of the electricity used in standby mode or off mode in the existing test procedures for gas-fired and oil-fired furnaces and boilers. Accordingly, in this notice, DOE is proposing added measurement provisions and expanded calculation procedures to account for electricity used in standby mode and off mode.

D. Electrical Energy Accounting in the Existing Test Procedures for Electric Furnaces and Boilers

The existing test procedure for electric furnaces and boilers requires a measurement of full-load electrical input (Ein). This value is then used to calculate annual energy consumption and costs. The efficiency is assumed to be 100 percent for indoor units, because it is assumed all input energy is delivered to the heated space as useful heat. The efficiency for outdoor units is reduced by an assigned or measured jacket loss.

As with fossil-fueled furnaces and boilers, the measurement of Ein and the associated accounting is best described in EISA 2007 terminology as “active mode.” There is no measurement or accounting of standby mode or off mode in the existing test procedures for electric furnaces and boilers. Accordingly, in this notice, DOE is proposing added measurement provisions and expanded calculation procedures to account for electricity used in standby mode and off mode.

E. Proposed Amendments

Because the current test procedures do not account for electricity consumption in standby mode and off mode, the residential furnace and boiler test procedures require amendment. First, measurements for standby mode and off mode electrical consumption rates (i.e., wattages) are needed. To this end, DOE proposes to add a new subsection to the furnace and boiler test procedure. Specifically, separate measurements of standby mode and off mode wattages would be added to section 8.0, Test procedure, of 10 CFR part 430, subpart B, appendix N. These provisions would reference IEC Standard 62301 for the measurement methodology itself. The added section would require only one measurement of wattage if there is no difference between standby mode and off mode. Separate measurements would be required if a difference is expected. Clarification as to the requirement for separate measurements is provided in the discussion in section III.I.

Second, the test procedure needs to specify the method for calculation of the annual standby mode and off mode electric energy consumption from the measured wattages. To this end, DOE proposes to add a new calculation subsection in section 10, Calculation of derived results from test measurements, of 10 CFR part 430, subpart B, appendix N. The proposed new subsection would be designated as 10.9, Average annual electric standby and off mode energy consumption. This added subsection would determine mode hours consistent with the annual accounting already in the furnace and boiler test procedure (i.e., the 8,760 hours accounting). Specifically, off mode hours would be assigned the current test procedure's value for non-heating season hours (4,600 hours; see ASHRAE 103-1993, section 11.2.12). “Standby mode hours” would be defined as the difference between the test procedure's value for heating season hours (4,160 hours, i.e, the numerical difference between total hours in a year and non-heating season hours) and the active mode hours. Active mode hours would be estimated as the tested unit's burner operating hours (BOH) for fossil-fueled furnaces and boilers, as discussed in section III.F below. Electric furnaces and boilers do not have a test procedure value for burner operating hours, so a calculated estimate of electric furnace and boiler active mode hours would be provided in this new subsection, as discussed in section III.G below.

Third, because it is technically feasible to do so, the test procedures must integrate the annual standby mode and off mode energy consumption into the existing calculations for annual energy consumption. To this end, DOE proposes to modify the equations in existing section 10.2.3, Annual auxiliary electrical energy consumption for gas and oil fueled furnaces or boilers, section 10.3, Average annual electric energy consumption for electric furnaces and boilers, 10.5.2 Average annual auxiliary electrical energy consumption for gas or oil-fueled furnaces and boilers located in a different geographic region of the United States and in buildings with different design heating requirements, and section 10.5.3, Average annual electric energy consumption for electric furnaces and boilers located in a different geographic region of the United States and in buildings with different design heating requirements. The proposed modifications would simply add the calculated annual standby mode and off mode electrical energy consumption to the existing calculations of annual electrical energy consumption. No changes to the current regulating quotient, AFUE, are proposed.

Finally, definitions would be added, as discussed in section III.A above, to clarify the application of these amendments.

An important implication resulting from these proposed modifications is that for fossil-fueled furnaces and boilers, the electrical standby mode and off mode energy consumption would be integrated automatically into the efficiency descriptor Energy Factor. Energy Factor is the ratio of annual fuel output of useful heat delivered to the heated space to the total annual energy consumption of both fossil fuel and electricity. Because annual electrical consumption would be increased due to the inclusion of standby mode and off mode consumption, the Energy Factor numerical value for residential furnaces and boilers will decrease.

F. Proposed Amendments' Relationship With Energy Conservation Standards, and Overall Discussion of Electrical Energy Use in Energy Conservation Standards for Residential Furnaces and Boilers

Section 310 of EISA 2007 requires two distinct activities relative to standby mode and off mode energy use. First, test procedures for all covered products must be amended to incorporate a means for measuring standby mode and off mode energy use, if such means are not already incorporated, by September 30, 2009. Second, any revised or new energy conservation standard adopted after July 1, 2010 must incorporate standby mode and off mode energy use by a single amended or new standard, if feasible; if that is not feasible, the standby mode and off mode energy use Start Printed Page 36965shall be regulated under a separate standard. (42 U.S.C. 6295(gg)(3))

The current energy conservation standard for residential furnaces and boilers is expressed in terms of AFUE, defined in 42 U.S.C. 6291(20) as the efficiency descriptor from the test procedures prescribed in section 6293. The definition of “efficiency descriptor” at 42 U.S.C. 6291(22) specifically identifies AFUE as the regulatory metric for furnaces. DOE prescribed an amended AFUE-based standard for furnaces and boilers in 2007. 72 FR 65136 (Nov. 19, 2007). As noted above, AFUE is a specific test procedure efficiency descriptor that does not incorporate any active, standby, or off mode electricity consumption. Since EISA 2007 requires any energy conservation standard adopted after July 1, 2010 to incorporate standby mode and off mode energy use, any future furnace/boiler energy conservation standard adopted after July 1, 2010 based solely on the existing AFUE equation would not satisfy the requirements of EISA 2007.

Therefore, the current rulemaking proposes amendments to the furnace and boiler test procedures that fully address the first EISA 2007 requirement to include standby mode and off mode energy consumption into the test procedures. Specifically, today's notice proposes to add new measurement procedures and to expand the annual energy consumption equations to include electrical standby mode and off mode energy use. (As discussed earlier in section III.B above, the current test procedure and AFUE already incorporate standby and off mode energy consumption applicable to fossil fuel use.) In the proposed amendments, electrical standby mode is defined as the off period during the heating season, and off mode is defined as the entire non-heating season. Taken together, these proposed amendments, when coupled with what is already measured in the existing procedures, would provide a full year's accounting of the energy consumption that section 310 of EISA 2007 requires each test procedure to include.

As mentioned above in III.F, in addition to this energy consumption accounting, one of the energy efficiency descriptors for these products (i.e., Energy Factor) would automatically reflect incorporation of electrical standby mode and off mode energy use without the need for specific amendment. This is because annual electricity consumption, which would be amended to include standby mode and off mode energy consumption and to provide a more comprehensive measurement, is part of the Energy Factor quotient. This increase in the calculated annual electrical consumption would, in turn, reduce slightly the Energy Factor numerical value. Energy Factor, as a stand-alone measurement, is not currently used to set standards for this product.

In addition, EISA 2007 amended 42 U.S.C. 6295(f)(4)(D) to require the Secretary to consider and prescribe furnace energy conservation standards or energy use standards for electricity used for purposes of circulating air through ductwork by December 31, 2013. (42 U.S.C. 6295(f)(4)(D)). DOE notes that there is some ambiguity associated with the language of this statutory provision. This language might appear to some as requiring DOE to prescribe a limited, separate standard that only addresses the active mode electricity used by the circulating fan on furnaces. Interpreting the statutory text in this manner would exclude the electricity energy consumption of boilers and the electricity consumption of furnace auxiliaries other than circulating fans. Although DOE plans to consider the scope of the statutory mandate under 42 U.S.C. 6295(f)(4)(D) in a subsequent standards rulemaking, today's proposed test procedure amendments are expected to be capable of addressing the range of electricity-consuming components for these products. Standard-setting issues, including any necessary additional test procedure modifications subsequently identified, will be fully addressed in that later standards rulemaking.

G. Active Mode Hours Approximated by Burner Operating Hours for Gas-Fueled or Oil-Fueled Furnaces and Boilers

As mentioned above in section III.E, today's proposal would assume that active mode hours of a particular furnace or boiler are equal to its burner operating hours (BOH). BOH is a calculated value in the existing test procedure for residential gas-fueled and oil-fueled furnaces and boilers. 10 CFR Part 430, Subpart B, Appendix N, section 10.2. BOH is determined by a complicated calculation procedure that starts with an estimate of the expected annual heating load and deduces the burner on hours necessary to generate the annual heating load.

BOH is exactly the active mode hours for the burner itself. However, the blower and other electric auxiliaries may have different active mode hours because of intentional time delays and overruns. To some, this might indicate a need to separately account for the standby mode and off mode energy use for each electrical auxiliary. As explained below, although these differences in active mode hours are accounted for in the test procedures, a separate accounting of each auxiliary's standby mode and off mode energy consumption is impracticable. For most furnaces and boilers, a single measured standby electrical wattage cannot be attributed to a particular auxiliary. In other words, since most furnaces and boilers have multiple electrical components, the measured standby mode or off mode wattage cannot easily be parsed out among multiple electrical components even if the exact active mode run hours for each component are known. The most precise approach to address this problem would be to abandon the BOH assumption of active mode for all auxiliaries and measure separately all the possible combinations of auxiliaries in active mode and ascribe different active mode hours and corresponding standby mode hours for each combination. However, such approach would result in a major increase in measurement and calculation complexity.

In addition, a possible slight inaccuracy resulting from the BOH assignment for active mode hours would have an insignificant effect on the overall accounting of standby mode and off mode energy consumption considering the order of magnitude difference between standby mode and off mode hours compared to active mode hours. For example, assuming a representative average BOH of 800 hours, the corresponding standby mode and off mode hours would be 7,960 hours (8,760 − 800)—a one percent error in BOH is a 0.1 percent error in standby mode and off mode accounting. Therefore, considering the impracticability of separate accounting of each auxiliary with no significant improvement in accuracy, DOE maintains that assigning active mode hours for all electrical auxiliaries as burner operating hours is appropriate and reasonable.

H. Active Mode Hours for Electric Furnaces and Boilers

The test procedures for residential electric furnaces and boilers do not have a calculation for burner operating hours. Since there is only one energy source and the efficiency is simply assigned, the current test procedure for electric furnaces and boilers calculates annual energy consumption directly from input energy measurements. Therefore, the option to use the test procedure value of burner operating hours to approximate active mode hours is not applicable. Today's proposal would include a separate calculation to estimate active Start Printed Page 36966mode hours for electric furnaces and boilers. The calculation is simply the quotient of the expected annual heating load (in Btu's) and the measured electrical input (in Btu's/hour). This results in an estimate of active mode hours which is consistent with the EISA 2007 definitions, and, since this calculation is nearly identical to that used for gas-fueled and oil-fueled furnaces and boilers, the resulting estimate is essentially equivalent to BOH for gas-fueled and oil-fueled furnaces and boilers.

I. Measurement of Standby Mode and Off Mode Wattages

Today's proposed amendments allow for a single wattage measurement to serve as both standby mode wattage and off mode wattage. DOE has tentatively concluded that this is a reasonable approach when there is expected to be no difference between the two modes in terms of wattage. This would be the case for most furnace and boiler designs where the appliance is not disconnected from the electric power source or where there is an absence of some other condition that would affect standby mode and off mode wattage. The utilization of a seasonal off switch would be a case where a reduction or elimination of off mode wattage compared to standby mode wattage can be expected. On units so equipped, a separate measurement of off mode wattage would be required, and a zero wattage for off mode would be a distinct possibility. Although DOE is not currently aware of some other factor or condition that might affect a difference between standby mode and off mode, a separate measure of off mode wattage would also be required anytime the wattages are known to differ.

DOE believes the phrases “reduction or elimination” and “seasonal off switch” are unambiguous and clear enough to direct the testing official as to when a separate measurement of off mode wattage is needed. DOE invites comments on the appropriateness and workability of these provisions.

J. Incorporation by Reference of IEC Standard 62301 (First Edition 2005-06) for Measuring Standby Mode and Off Mode Power Consumption in Furnaces and Boilers

As noted previously, EPCA, as amended by EISA 2007, requires that test procedures “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. * * *” (42 U.S.C. 6295(gg)(2)(A)). Today's proposed amendments would reference IEC Standard 62301 in terms of the methodology to obtain the standby mode and off mode measured wattage. The proposed test procedure amendments would use these measured wattages in calculations to accomplish the incorporation of standby mode and off mode energy consumption into the test procedures. DOE reviewed IEC Standard 62301 and sees no need to modify or eliminate any existing IEC provisions. IEC Standard 62301's provisions pertaining to supply voltage waveform and power measurement accuracy apply to any measurement of low electrical power, including the low power measurement expected during furnace and boiler standby mode and off mode operation. The IEC Standard 62301 is concise and well organized and should not pose a significant burden to the furnace and boiler manufacturers or the associated testing industry.

DOE also reviewed IEC Standard 62087, which specifies methods of measurement for the power consumption of television receivers, video cassette recorders, 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 appliances such as furnaces. Therefore, DOE determined that IEC Standard 62087 was not applicable to this rulemaking.

Finally, DOE recognizes that the IEC is currently developing an updated test procedure, IEC Standard 62301 (Ed. 2.0), which would include definitions of “off mode,” “network connected standby mode,” and “disconnected mode,” and which would also revise the current IEC Standard 62301 definition of “standby mode.” Given the definitions proposed in this NOPR which are tailored to address furnaces and boilers, DOE does not believe that these IEC modifications would likely impact or improve the amendments proposed here, because the measurement provisions of IEC Standard 62301, which are needed to implement EISA 2007 for furnaces and boilers, are not expected to change appreciably. Therefore, DOE does not plan to wait for such amendments, particularly given the upcoming statutory deadline. Thus, DOE plans to use the current version of IEC Standard 62301 in today's proposed test procedure. After the final rule is published, further amendments to the referenced IEC standard by the standard-setting organization would become part of the DOE test procedure only if DOE subsequently amends the test procedure to incorporate them through a separate rulemaking.

K. Compliance With Other EPCA Requirements

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 believes that the incorporation of IEC Standard 62301, along with the modifications and additional calculations described above, would satisfy this requirement.

Today's proposed amendments to the DOE test procedure would incorporate a test standard that is widely accepted and used internationally to measure electric power in standby mode and off mode. Based on its analysis of IEC Standard 62301, DOE determined that the test methods and equipment that the amendment would require for measuring standby power do not differ substantially from the test methods and equipment in the current DOE test procedure for furnaces and boilers. Therefore, testing of furnaces and boilers pursuant to today's proposed amendments would not require any significant investment in test facilities or new equipment. In addition, the 8,760-hour accounting described above constitutes a full accounting of the annual energy consumption for furnaces and boilers. For these reasons, DOE has concluded that the amended test procedure would produce test results that yield energy consumption values of a covered product during a representative period of use, and that the test procedure would not be unduly burdensome to conduct.

IV. Procedural Requirements

A. Review Under Executive Order 12866

Today's 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 Start Printed Page 36967of an initial regulatory flexibility analysis for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by Executive Order 13272, “Proper Consideration of Small Entities in Agency Rulemaking,” 67 FR 53461 (August 16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the potential impacts of its rules on small entities are properly considered during the 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 amendments to test procedures that will be used to test compliance with energy conservation standards for the products that are the subject of this rulemaking. The proposed rule affects residential furnace and boiler test procedures.

DOE has tentatively concluded that the proposed rule would not have a significant economic impact on a substantial number of small entities 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 only possible impact is the added cost to conduct the measurements required in the IEC Standard 62301. As discussed in section III.K above, this would not represent a substantial burden to any manufacturer of furnaces and boilers, small or large.

In addition, the Small Business Administration (SBA) considers an entity to be a small business if, together with its affiliates, it employs fewer 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 333415, which applies to Air-Conditioning and Warm Air Heating Equipment and Commercial and Industrial Refrigeration Equipment Manufacturing (including residential furnaces and boilers manufacturers) is 750 employees.[10] DOE reviewed the Air-Conditioning, Heating, and Refrigeration Institute's Directory of Certified Product Performance for Residential Furnaces and Boilers (2009),[11] the ENERGY STAR Product Databases for Gas and Oil Furnaces (May 15, 2009),[12] the California Energy Commission's Appliance Database for Residential Furnaces and Boilers,[13] and the Consortium for Energy Efficiency's Qualifying Furnace and Boiler List (April 2, 2009).[14] From this review, DOE found there were approximately 25 small businesses within the furnace and boiler industry. Even though there are a significant number of small businesses within the furnace and boiler industry, DOE does not believe the test procedure amendments described in this proposed rule would represent a substantial burden to any manufacturer, including small manufacturers, as explained above. DOE requests comments on its characterization of the residential furnace and boiler industry in terms of the number of and impacts on small businesses.

For these reasons, DOE certifies that the proposed rule, if adopted, 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 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 proposed rule, DOE proposes test procedure amendments that it expects will be used to develop and implement future energy conservation standards for residential furnaces and boilers. 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, appendix A, paragraph A5. Today's proposed rule would not affect the amount, quality, or distribution of energy usage, and, therefore, would not result in any environmental impacts.[15] 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 4, 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, no further action is required to comply with Executive Order 13132.

F. Review Under Executive Order 12988

Regarding the review of existing regulations and the promulgation of new regulations, section 3(a) of Executive Order 12988, “Civil Justice Reform,” 61 FR 4729 (Feb. 7, 1996), imposes on Federal agencies the general Start Printed Page 36968duty 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 no further action is required under UMRA.

H. Review Under the Treasury and General Government Appropriations Act, 1999

Section 654 of the Treasury and General Government Appropriations Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family Policymaking Assessment for any rule that may affect family well-being. Today's proposed rule would have no impact on the autonomy or integrity of the family as an institution. Accordingly, DOE has concluded that it is not necessary to prepare a Family Policymaking Assessment.

I. Review Under Executive Order 12630

DOE has determined, under Executive Order 12630, “Governmental Actions and Interference with Constitutionally Protected Property Rights,” 53 FR 8859 (March 18, 1988), that this regulation would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution.

J. Review Under 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 and concluded that it is consistent with applicable policies in the OMB and DOE 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. The definition of a “significant energy action” is 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 regulatory action is not a significant regulatory action under Executive Order 12866. Moreover, it would not have a significant adverse effect on the supply, distribution, or use of energy. It has likewise not been designated as a significant energy action by the Administrator of OIRA. Therefore, it is not a significant energy action. 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 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 rule would modify the test procedure for residential furnaces and boilers by incorporating 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 comments on the adequacy and appropriateness of IEC Standard 62301 in general, and whether there is a need to modify or depart from the provisions in the IEC Standard 62301 with regard to residential furnaces and boilers.

2. Measurement of Standby Mode and Off Mode Wattages

To avoid unnecessary measurement burden, today's proposed amendments allow a single measurement to serve as both standby mode and off mode wattages. DOE invites comments on the appropriateness and workability of these provisions.

3. Proposed Amendments' Relationship With Energy Conservation Standards for Residential Furnaces and Boilers

DOE believes today's proposed residential furnace and boiler test procedure amendments are sufficient to allow for implementation of EISA 2007-related energy conservation standards requirements for residential furnaces and boilers (e.g., the added provisions will allow a subsequent standard to address standby mode and off mode energy consumption). DOE invites comment on the overall issue of the test procedure's ability to measure Start Printed Page 36970electricity use (active mode as well as standby mode and off mode) in the context of residential furnace and boiler efficiency standards.

2.0. Definitions.

* * * * *

2.5 IEC 62301 means the test standard published by the International Electrotechnical Commission (IEC), titled “Household electrical appliances—Measurement of standby power,” Publication 62301 (First Edition 2005-06). (Incorporated by reference, see § 430.3.)

2.6. Active mode means the condition during the heating season in which the furnace or boiler is connected to the power source, and either the burner, electric resistance elements, or any electrical auxiliaries such as blowers or pumps, are activated.

2.7 Standby mode means the condition during the heating season in which the furnace or boiler is connected to the power source, and neither the burner, electric resistance elements, nor any electrical auxiliaries such as blowers or pumps, are activated.

2.8 Off mode means the condition during the non-heating season in which the furnace or boiler is connected to the power source, and neither the burner, electric resistance elements, nor any electrical auxiliaries such as blowers or pumps, are activated.

2.9 Seasonal off switch means the switch on the furnace or boiler that, when activated, results in a measurable change in energy consumption between the standby and off modes.

* * * * *

8.0 Test Procedure.

* * * * *

8.6 Measurement of electrical standby and off mode power.

8.6.1 Standby power. With all electrical components of the furnace or boiler not activated, measure the standby power (PSB) in accordance with the procedures in IEC 62301 (incorporated by reference, see § 430.3). Utilize the accuracy and precision specifications in IEC Standard 62301 in lieu of those in ASHRAE Standard 103-1993. Measure the wattage so that all possible standby mode wattage for the entire appliance is recorded, not just the standby mode wattage of a single auxiliary.

8.6.2 Off mode power. If the unit is equipped with a seasonal off switch or there is an expected difference between off mode power and standby mode power, measure off mode power (POFF) in accordance with the standby power procedures in IEC 62301 (incorporated by reference, see § 430.3). Utilize the accuracy and precision specifications in IEC Standard 62301 in lieu of those in ASHRAE Standard 103-1993. Measure the wattage so that all possible off mode wattage for the entire appliance is recorded, not just the off mode wattage of a single auxiliary. If there is no expected difference in off mode power and standby power, let POFF = PSB, in which case no separate measurement of off mode power is necessary.

3.  EISA 2007 directs DOE to also consider IEC Standard 62087 when amending its test procedures 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.

4.  In either case, for the reasons explained below, these new modes (i.e., standby mode and off mode) would be fully accounted for in the residential furnace and boiler test procedure, but they might not be fully accounted for in the regulating metric (annual fuel utilization efficiency) set by statute. Instead, it may be necessary to specify integrated metrics by fuel type (i.e., fossil fuel versus electricity).
