Energy Conservation Program for Consumer Products: Test
Procedures for Residential Furnaces and Boilers
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
[[Page 36960]]
these products. DOE is also announcing a public meeting to discuss and
receive comments on the issues presented in this notice.

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))
---------------------------------------------------------------------------
\1\ All references to EPCA refer to the statute as amended
through the Energy Independence and Security Act of 2007, Public Law
110-140.
---------------------------------------------------------------------------
Under the Act, this program consists essentially of three parts:
(1) Testing; (2) labeling; and (3) 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
[[Page 36961]]
determine 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))
---------------------------------------------------------------------------
\2\ IEC standards are available for purchase at: http://www.iec.ch.
---------------------------------------------------------------------------
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))
---------------------------------------------------------------------------
\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.
---------------------------------------------------------------------------
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
[[Page 36962]]
proposal 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.
---------------------------------------------------------------------------
\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).
---------------------------------------------------------------------------
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
[[Page 36963]]
and 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).
---------------------------------------------------------------------------
\5\ Nameplate input is the energy supply rate in Btu's per hour
which is physically listed on the tested furnace or boiler. Testing
at this input would be the most appropriate and consistent way to
specify a uniform test input rate.
---------------------------------------------------------------------------
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\
---------------------------------------------------------------------------
\6\ Sensible heat loss is the energy loss associated with the
elevated temperature (as ``sensed'' by a thermometer) of the exiting
flue gases.
---------------------------------------------------------------------------
Ls,off = off-cycle sensible heat loss
Li,on = on-cycle infiltration loss \7\
---------------------------------------------------------------------------
\7\ Infiltration loss is the energy loss associated with the
added leakage a home would experience because of the exiting flue
gases.
---------------------------------------------------------------------------
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.
---------------------------------------------------------------------------
\8\ Each year comprises 8,760 hours--i.e., (365 days/year) x (24
hours/day) = 8,760 hours/year.
---------------------------------------------------------------------------
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
[[Page 36964]]
ascribed 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.
---------------------------------------------------------------------------
\9\ An induced draft fan draws air into the combustion chamber.
In contrast, a forced draft fan forces air into the combustion
chamber.
---------------------------------------------------------------------------
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
[[Page 36965]]
shall 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
[[Page 36966]]
mode 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
[[Page 36967]]
of 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.
---------------------------------------------------------------------------
\15\ Categorical Exclusion A5 provides: ``Rulemaking
interpreting or amending an existing rule or regulation that does
not change the environmental effect of the rule or regulation being
amended.''
---------------------------------------------------------------------------
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
[[Page 36968]]
duty to adhere to the following requirements: (1) Eliminate drafting
errors and ambiguity; (2) write regulations to minimize litigation; (3)
provide a clear legal standard for affected conduct rather than a
general standard; and (4) promote simplification and burden reduction.
Section 3(b) of Executive Order 12988 specifically requires that
Executive agencies make every reasonable effort to ensure that the
regulation specifies the following: (1) The preemptive effect, if any;
(2) any effect on existing Federal law or regulation; (3) a clear legal
standard for affected conduct while promoting simplification and burden
reduction; (4) the retroactive effect, if any; (5) definitions of key
terms; and (6) other important issues affecting clarity and general
draftsmanship under any guidelines issued by the Attorney General.
Section 3(c) of Executive Order 12988 requires Executive agencies to
review regulations in light of applicable standards in sections 3(a)
and 3(b) to determine whether they are met or whether it is
unreasonable to meet one or more of them. DOE has completed the
required review and determined that, to the extent permitted by law,
this proposed rule meets the relevant standards of Executive Order
12988.
G. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub.
L. 104-4; 2 U.S.C. 1501 et seq.) requires each Federal agency to assess
the effects of Federal regulatory actions on State, local, and Tribal
governments and the private sector. For a proposed regulatory action
likely to result in a rule that may cause the expenditure by State,
local, and Tribal governments, in the aggregate, or by the private
sector of $100 million or more in any one year (adjusted annually for
inflation), section 202 of UMRA requires a Federal agency to publish
estimates of the resulting costs, benefits, and other effects on the
national economy. (2 U.S.C. 1532(a), (b)) UMRA also requires a Federal
agency to develop an effective process to permit timely input by
elected officers of State, local, and Tribal governments on a proposed
``significant intergovernmental mandate,'' and requires an agency plan
for giving notice and opportunity for timely input to potentially
affected small governments before establishing any requirements that
might significantly or uniquely affect such governments. On March 18,
1997, DOE published a statement of policy on its process for
intergovernmental consultation under UMRA. 62 FR 12820. (The policy is
also available at http://www.gc.doe.gov). Today's proposed rule
contains neither an intergovernmental mandate nor a mandate that may
result in an expenditure of $100 million or more in any year, so 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.

copy of the document with that information deleted. DOE will determine
the confidential status of the information and treat it accordingly.
Factors of interest to DOE when evaluating requests to treat
submitted information as confidential include the following: (1) A
description of the items; (2) whether and why such items are
customarily treated as confidential within the industry; (3) whether
the information is generally known by or available from other sources;
(4) whether the information was previously made available to others
without obligation concerning its confidentiality; (5) an explanation
of the competitive injury to the submitting person that would result
from public disclosure; (6) when such information might lose its
confidential character due to the passage of time; and (7) why
disclosure of the information would be contrary to the public interest.
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
[[Page 36970]]
electricity use (active mode as well as standby mode and off mode) in
the context of residential furnace and boiler efficiency standards.
VI. Approval of the Office of the Secretary
The Secretary of Energy has approved publication of this notice of
proposed rulemaking.

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 Sec. 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 Sec. 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.
