Background On March 10, 2015, DOE published in the Federal Register a notice of proposed rulemaking (NOPR) and public meeting to amend energy conservation standards for residential non-weatherized gas furnaces (NWGF) and mobile home gas furnaces (MHGF). 80 FR 13119. The proposed standards, which are expressed as minimum annual fuel utilization efficiencies (AFUE), are shown in Table I.1. These proposed standards, if adopted, would apply to all products listed in Table I.1 and manufactured in, or imported into, the United States on or after the date 5 years after the publication of the final rule for this rulemaking.

Mobile Home Gas-Fired Furnaces ................................. AFUE % 92 92 A number of stakeholders objected to a national standard at 92 percent AFUE, which would effectively only be able to be met by using condensing technology. The objections raised by stakeholders covered a wide range of issues, but the negative impacts of the proposed E:\FR\FM\14SEP1.SGM 14SEP1 tkelley on DSK3SPTVN1PROD with PROPOSALS Federal Register / Vol. 80, No. 177 / Monday, September 14, 2015 / Proposed Rules standards on some furnace consumers were highlighted by many stakeholders. A letter dated June 8, 2015, signed by 121 members of the U.S. House of Representatives, expressed concern that a nationwide energy efficiency standard that effectively precludes a consumer from choosing to install a noncondensing furnace would result in many homeowners either abandoning the use of natural gas to heat their homes or paying substantially more for the installation of a furnace that meets the new standard. It stated that many families will be faced with the difficult choice of having to replace their noncondensing furnace with either a condensing furnace with higher installation costs or electric heat and accompanying higher monthly energy bills. (United States House of Representatives, No. 67 at p. 1) Comments from the Pennsylvania Chambers of Commerce, Business, and Industry, Meeks, Payne, Jr., Bishop, Jr., and Carrier make similar statements. (Pennsylvania Chambers of Commerce, Business, and Industry, No. 82 at p. 1; Meeks, No. 140 at p. 1; Payne, Jr., No. 75 at p. 1; Bishop, Jr., No. 76 at p. 1) The American Gas Association (AGA), Goodman, and American Energy Alliance (AEA et al.) stated that even assuming DOE’s analysis is correct, many consumers could incur costs under the proposed standard. They stated that, according to DOE’s analysis, 20 percent of households nationwide would face higher life-cycle costs under the proposed standard, and in the replacement market, one-quarter of all households replacing their natural gas furnaces would see a life-cycle cost increase. (AGA, No. 118 at p. 27; AEA et al., No. 69 at p. 1; Goodman, No. 135 at p. 2) AGA, Goodman, and Southern Gas Association (SGA) added that consumers in the South and low-income families would be disproportionately impacted. (AGA, No. 118 at p. 27; Goodman, No. 135 at p. 2; SGA, No. 145 at p. 1) The Air-Conditioning, Heating, and Refrigeration Institute (AHRI), Carrier, Rheem, and Ingersoll Rand expressed concern that the proposed standards will result in 10–20 percent of homes switching from gas furnaces to electric heat pumps because venting of a condensing gas furnace is difficult to impossible. (AHRI, No. 159 at p. 3; Carrier, No. 116 at p. 2; Rheem, No. 142 at p. 3; Ingersoll Rand, No. 156 at p. 2) AGA expressed a similar concern, and asserted that the resulting adverse energy and environmental impacts of this fuel switching are very substantial. (AGA, No. 118 at p. 28) VerDate Sep<11>2014 16:52 Sep 11, 2015 Jkt 235001 Several stakeholders, who expressed general support for the proposed standards and suggested more stringent standards could be justified, provided a recommendation for reducing negative impacts on some furnace consumers while maintaining the overall economic and environmental benefits of the standards. The American Council for an Energy-Efficient Economy (ACEEE) recommended that DOE establish a separate product class for small furnaces (tentatively those with an input capacity of 50,000 Btu/hour or less) and leave the standard level for these units at 80percent AFUE, while adopting a higher standard level of 95-percent AFUE for larger furnaces. (ACEEE, No. 113 at p. 1) The Alliance to Save Energy made a similar recommendation, but referred to an input capacity of no more than 50,000 to 65,000 Btu/hour for smaller furnaces. (Alliance to Save Energy, No. 115 at p. 1) The Natural Resources Defense Council (NRDC) urged DOE to adopt an 80-percent AFUE standard level for furnaces below a specified maximum capacity threshold, and set the capacity threshold low enough that the national energy, economic, and environmental benefits are largely preserved while allowing consumers in small and moderately-sized, well insulated and weatherized homes in moderate and warm climates to have a non-condensing option. (NRDC, No. 134 at p. 2) AGLR stated that DOE should establish a separate product class for small furnaces with an input capacity of less than 45,000 Btu/hour, citing section 305(f) of EPCA as authority for DOE to establish separate product classes based on product capacity. (AGLR, No. 112 at pp. 15–16) ACEEE also stated that creating two product classes based on furnace size would reduce the number of households that would experience net costs under the proposed standard (many of whom are in the south). ACEEE stated that many of the consumers who would experience net costs will have small furnaces and recommended that DOE specifically examine this issue and estimate the economics of separate standard levels as a function of furnace input capacity. ACEEE noted that a size threshold provides another option for some households with very high installation costs—if they weatherize their home and get the needed capacity below 50,000 Btu/h, they can avoid the extra installation cost of a condensing furnace. ACEEE added that a size threshold would not present the potential enforcement challenges associated with regional standards. (ACEEE, No. 113 at p. 3) PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 55039 Although DOE believes that the standards proposed in the March 2015 NOPR meet the statutory criteria for amended standards, given the concerns and suggestions described above, DOE undertook an analysis of the consumer economics and national impacts of establishing separate standard levels for large and small residential furnaces. In so doing, it examined the effect of alternative size thresholds for a small furnace. Because the issues raised by stakeholders primarily concern NWGFs, DOE only considered that product in its analysis and did not examine mobile home gas furnaces. The analysis is described in section II of this NODA; section III provides the results of the analysis. DOE notes that this NODA does not propose any energy conservation standards for residential furnaces. DOE may revise the analyses presented in today’s NODA based on any new or updated information or data it obtains during the course of the rulemaking. DOE encourages stakeholders to provide any additional data or information that may improve the analysis. II. Summary of the Analyses Performed by DOE DOE conducted an analysis of the consumer impacts (life-cycle cost and payback period) and national impacts (national energy savings and net present value of national benefits) of potential standard levels for the considered NWGF product classes. The tools used in preparing these analyses and their respective results are available at: https://www1.eere.energy.gov/buildings/ appliance_standards/ rulemaking.aspx?ruleid=62. Each individual spreadsheet includes an introduction that provides an overview of the contents of the spreadsheet. These spreadsheets present the various inputs and outputs to the analysis and, where necessary, instructions. Brief descriptions of the analyses and of the supporting spreadsheet tools are provided below. If DOE were to consider adopting energy conservation standards for residential furnaces that set separate levels based on input capacity, it would do so in a future supplemental NOPR (SNOPR). DOE would also publish a technical support document (TSD) containing a detailed written account of the analyses performed in support of the SNOPR, which will include updates to the analyses made available in this NODA. The analysis conducted for this NODA used the same analytical E:\FR\FM\14SEP1.SGM 14SEP1 55040 Federal Register / Vol. 80, No. 177 / Monday, September 14, 2015 / Proposed Rules framework as the March 2015 NOPR.1 Key aspects of the present analysis and DOE’s updates to the NOPR analysis are described in the sections below. would need to use condensing technology to meet the standard. Thus, households installing a small furnace would not need to incur the costs associated with installing a condensing furnace. A. Introduction The analysis conducted for this NODA estimated impacts for the potential standard level combinations shown in Table II.1. The key aspect of this analysis is that only large furnaces TABLE II.1—POTENTIAL STANDARD LEVEL COMBINATIONS ANALYZED FOR LARGE AND SMALL FURNACES Furnance size Annual fuel utilization efficiency (%) Large ................................................................................................................ Small ................................................................................................................ This NODA analysis used the same sample of residential furnace consumers as the March 2015 NOPR. Each sample household was assigned a furnace size (in terms of input capacity) based on a number of features, as discussed in section II.C. The share of households 90 80 that would install a small furnace depends on how ‘‘small furnace’’ is defined in terms of input capacity. For this analysis, DOE considered the following small furnace definitions: ≤45 kBtu/hour, ≤50 kBtu/hour, ≤55 kBtu/ hour, ≤60 kBtu/hour, and ≤65 kBtu/ 92 80 95 80 98 80 hour. In each case, large furnaces would be defined as all sizes above the given thresholds. The share of households that would install a furnace meeting a small furnace standard rises as the size cutoff in the small furnace definition increases, as illustrated in Table II.2.2 TABLE II.2—SHARE OF SAMPLE HOUSEHOLDS BY FURNACE SIZE [percent] Small furnace definition Furnace size ≤45 kBtu/hour ≤50 kBtu/hour ≤55 kBtu/hour ≤60 kBtu/hour ≤65 kBtu/hour Large ....................................................................................

Engineering Analysis tkelley on DSK3SPTVN1PROD with PROPOSALS The engineering analysis establishes the relationship between the manufacturer production cost (MPC) and energy efficiency for residential furnaces. This relationship between MPC and energy efficiency serves as the basis for calculations performed in the other analysis tools to estimate the costs and benefits to individual consumers, manufacturers, and the nation. For each NWGF efficiency level that was analyzed, the MPC was estimated for four furnace capacities (60 kBtu/hour, 80 kBtu/hour, 100 kBtu/hour, and 120 kBtu/hour). For the NODA analysis, DOE updated the MPCs from the NOPR to incorporate the most recent available data for material,3 component, labor, and overhead costs, and also updated the MPCs to 2014$. 1 Please see the March 2015 NOPR and the accompanying TSD for details, which are available at https://www1.eere.energy.gov/buildings/ appliance_standards/rulemaking.aspx?ruleid=62. 2 The shares in Table II.2 reflect the likelihood that some consumers would down-size a new VerDate Sep<11>2014 17:33 Sep 11, 2015 Jkt 235001 C. Life-Cycle Cost and Payback Period Analyses The life-cycle cost (LCC) and payback period (PBP) analyses determine the economic impact of potential standards on individual consumers who purchase a furnace in the expected compliance year (assumed to be 2021 for this analysis). The LCC is the total cost of purchasing, installing and operating a residential furnace over the course of its lifetime. DOE determines the LCC by considering: (1) The total installed cost to the consumer (which consists of manufacturer selling price, distribution channel markups, sales taxes, and installation costs); (2) the annual energy consumption (natural gas or LPG and electricity) of residential furnaces as they are used in the field; (3) the operating cost of residential furnaces (i.e., energy cost and maintenance and repair cost); (4) equipment lifetime; and (5) a discount rate that reflects the consumer cost of capital and puts the furnace to meet the ‘‘small furnace’’ definition. See section II.C for discussion. 3 DOE uses 5-year averages for metal materials and current prices for all other materials. PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 LCC in present-value terms. The PBP represents the number of years needed to recover the increase in purchase price of higher-efficiency residential furnaces through savings in the operating cost. For each considered standards case, DOE measures the change in LCC relative to a no-new-standards case, which reflects the market in the absence of amended energy conservation standards, including market trends for equipment that exceeds the current energy conservation standards. In the March 2015 NOPR and in today’s NODA, DOE developed nationally-representative household samples for residential furnaces from the 2009 Residential Energy Consumption Survey (RECS).4 DOE analyzed the net effect of potential amended residential furnace standards on consumers by calculating the LCC savings and PBP for each household by efficiency level. DOE performed the LCC and PBP analyses using a spreadsheet model 4 U.S. Department of Energy: Energy Information Administration, Residential Energy Consumption Survey: 2009 RECS Survey Data (2013), available at: https://www.eia.gov/consumption/residential/data/ 2009/ (last accessed July 29, 2015).

Each Monte Carlo simulation consists of 10,000 LCC and PBP calculations using input values that are either sampled from probability distributions and household samples or characterized with single point values. The analytical results include a distribution of 10,000 data points showing the range of LCC savings for a given efficiency level relative to the nonew-standards case efficiency distribution. In performing an iteration of the Monte Carlo simulation for a given consumer, product efficiency is chosen based on its probability. If the chosen product efficiency is greater than or equal to the efficiency of the standard level under consideration, the LCC and PBP calculation reveals that a consumer is not impacted by the standard level. By accounting for consumers who already purchase more-efficient products, DOE avoids overstating the potential benefits from increasing product efficiency. tkelley on DSK3SPTVN1PROD with PROPOSALS 1. Furnace Size Assignment For the March 2015 NOPR, DOE assigned an input capacity for the existing furnace of each housing unit based on an algorithm that correlates the heating square footage and the outdoor design temperature for heating (i.e., the temperature that is exceeded by the 30year minimum average temperature 1 percent of the time) with the distribution of input capacity of furnaces.6 DOE assumed that, for the new furnace installation, the input capacity would remain the same. DOE’s analysis accounted for the typical oversizing of furnace capacity (i.e., the furnace is larger than it needs to be to fulfill the building heating load). If there is a separate standard for small furnaces, DOE expects that some consumers who would otherwise install a typically-oversized furnace would choose to down-size in order to be able to purchase a non-condensing furnace. For the NODA analysis, DOE identified those sample households that might 5 Crystal Ball is a commercial software program developed by Oracle and used to conduct stochastic analysis using Monte Carlo simulation. A Monte Carlo simulation uses random sampling over many iterations of the simulation to obtain a probability distribution of results. Certain key inputs to the analysis are defined as probability distributions rather than single-point values. 6 The distribution of input capacity is based on shipments data by input capacity bins for the year 2000 provided by AHRI (AHRI (formerly GAMA). Furnace and Boiler Shipments data provided to DOE for Furnace and Boiler ANOPR. January 23, 2002). AHRI data was further disaggregated into 5kBtu/h bins using the reduced models dataset from the NOPR analysis. Appendix 7B of the NOPR TSD provides details about furnace sizing method.

DOE first determined if a household would install a non-condensing furnace with an input capacity greater than the small furnace size limit without amended standards. In the standards case, DOE assumed that a fraction of such consumers would down-size to the input capacity limit for small furnaces. 2. Energy Prices For this NODA, DOE updated current energy prices and also the projection of future energy prices. Current average and marginal monthly energy prices are based on the latest data (2013 energy prices) from EIA (Form 861 data 7 to calculate commercial electricity prices, Natural Gas Navigator 8 to calculate commercial natural gas prices, and State Energy Data System 9 to calculate LPG prices). The update to 2013 energy prices had a very small impact on the LCC and PBP results.10 Future energy prices are based on the projection of average annual percent change in national-average residential natural gas and electricity prices in the Annual Energy Outlook 2015 (AEO 2015). 3. Other Updates For this NODA, DOE updated the efficiency distribution in the no-newstandards case to reflect AHRI shipments data from 2010 to 2014.11 The update resulted in decreased fraction of consumers being impacted by an efficiency standard requiring efficiencies of 90-percent AFUE and above.12 DOE also made minor updates to the markups, product price trend, and the building shell efficiency and climate indexes used to adjust energy use. These are described in the LCC spreadsheet. 7 Energy Information Administration (EIA), Survey form EIA–861—Annual Electric Power Industry Report (Available at: https://www.eia.gov/ electricity/data/eia861/) (Last accessed July 15, 2015). 8 Energy Information Administration (EIA), Natural Gas Navigator (Available at: https:// tonto.eia.doe.gov/dnav/ng/ng_pri_sum_dcu_nus_ m.htm) (Last accessed July 15, 2015). 9 Energy Information Administration (EIA), State Energy Data System (SEDS) (Available at: https:// www.eia.gov/state/seds/) (Last accessed July 15, 2015). 10 For the NOPR, 2012 energy prices from the same sources were used. 11 Air-Conditioning, Heating, and Refrigeration Institute.

Based on the AHRI shipments data, DOE’s estimate of the condensing furnace market share in 2021 increased from 47-percent in the NOPR to 53-percent in the NODA. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 55041 D. National Impact Analysis The national impacts analysis (NIA) estimates the national energy savings (NES) and the net present value (NPV) of total consumer costs and savings expected to result from potential new standards. DOE calculated NES and NPV as the difference between a case without amended standards and each standards case. DOE calculated the annual energy consumption for each case using the appropriate per-unit annual energy use data multiplied by the projected residential furnaces shipments for each year. To estimate impacts of separate standards for small and large furnaces, DOE needed to disaggregate NWGF shipments by input capacity. To do so, DOE assumed that the shares of each size category in NWGF shipments are the same as the shares estimated for the household sample. The shares were assumed to remain constant over time. Cumulative energy savings are the sum of the annual NES determined for the lifetime of furnaces shipped during a 30-year period assumed to start in the expected compliance year. Energy savings include the full-fuel cycle energy savings (i.e., the energy needed to extract, process, and deliver primary fuel sources such as coal and natural gas, and the conversion and distribution losses of generating electricity from those fuel sources). To develop the national NPV of consumer benefits from potential energy conservation standards, DOE calculated projected annual operating costs (energy costs and repair and maintenance costs) and annual installation costs for the nonew-standards case and the standards cases. DOE calculated annual energy expenditures from annual energy consumption using forecasted energy prices in each year. DOE calculated annual product expenditures by multiplying the price per unit times the projected shipments in each year. The aggregate difference each year between operating cost savings and increased installation costs is the net savings or net costs. DOE multiplies the net savings in future years by a discount factor to determine their present value. DOE estimates the NPV of consumer benefits using both a 3-percent and a 7percent real discount rate, in accordance with guidance provided by the Office of Management and Budget (OMB) to Federal agencies on the development of regulatory analysis.13 13 Office of Management and Budget, OMB Circular A–4, section E, Identifying and Measuring Benefits and Costs (2003), available at https:// www.whitehouse.gov/omb/memoranda/m0321.html. E:\FR\FM\14SEP1.SGM 14SEP1 55042 Federal Register / Vol. 80, No. 177 / Monday, September 14, 2015 / Proposed Rules For the NODA analysis, DOE updated energy price trends and several other inputs with data from AEO 2015, as described in the NIA spreadsheet. III. Results of the Analysis A. Economic Impacts on Consumers As mentioned in section II.C, for each considered standards case, DOE measures the change in LCC relative to a no-new-standards case. For example, in the case of a separate standard of 90- percent AFUE for large furnaces and 80percent AFUE for small furnaces, the analysis reflects the likelihood that some consumers would purchase a furnace at or above those efficiency levels without standards, and thus would not be affected by the standards. The average LCC savings in Table III.1 only include those consumers who would be affected at a given standard level. Table III.2 shows the percentage of consumers that would experience a net cost under each considered standards case, and Table III.3 shows the percentage of consumers in the South that would experience a net cost.14 For these consumers, the LCC would increase under the standard compared to the furnace they would purchase in no-new-standards case. As expected, the percentage of consumers that would experience a net cost declines as the definition of small furnace expands to include more furnaces.

The impacts of a separate standard for large and small furnaces would vary depending on the small furnace definition. For example, if the definition was ≤60 kBtu/hour instead of ≤55 kBtu/hour, the difference between the single standard for all furnaces and separate standards for large and small furnaces would be greater than shown. 14 The analysis used the same definition of the South region as the March 2015 NOPR. 15 The results for a single standard for all furnaces differ slightly from the results in the March 2015 NOPR because of the input revisions discussed in section II. DOE believes that showing a direct comparison with the NOPR results would not serve the purpose of the NODA analysis.

In the NOPR analysis, DOE estimated that some consumers faced with significant costs to install a condensing furnace would instead choose to switch to electric heating with a heat pump or electric furnace. If there were a separate, lower standard level for small furnaces, fewer consumers would be faced with installing a condensing furnace, and there would be less switching.

Close to 60 percent of low-income households in RECS 2009 VerDate Sep<11>2014 16:52 Sep 11, 2015 Jkt 235001 are either renters or residents of public housing. In these cases, the furnace would be purchased by the property owner, and the cost of a higher-efficiency furnace might be passed on over time in the rent (or perhaps not all in the case of public housing). PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 DOE’s current analysis assumes that in cases where the property owner does not pay for energy, the cost of a higher-efficiency furnace is passed on immediately, which would tend to overstate any negative impact.

National Impacts The estimated national energy savings (full-fuel-cycle) of the considered combinations of minimum AFUE for large and small furnaces are shown in Table III.8. Table III.9 and Table III.10 show the national NPV of benefits for alternative furnace standard level combinations at 7-percent and 3-percent discount rates, respectively. The national energy savings decrease as the small furnace definition expands.

The national energy savings are higher in the case of a separate standard for large and small furnaces mainly because there is less switching from gas to electric heating.17 The NPV is higher in the case of a separate standard for large and small furnaces mainly because the LCC savings are higher. The impacts of a separate standard for large and small furnaces would vary depending on the small furnace definition. TABLE III.11—COMPARISON OF NATIONAL IMPACTS OF SINGLE STANDARD VS.

I. Background

    On March 10, 2015, DOE published in the Federal Register a notice 
of proposed rulemaking (NOPR) and public meeting to amend energy 
conservation standards for residential non-weatherized gas furnaces 
(NWGF) and mobile home gas furnaces (MHGF). 80 FR 13119. The proposed 
standards, which are expressed as minimum annual fuel utilization 
efficiencies (AFUE), are shown in Table I.1. These proposed standards, 
if adopted, would apply to all products listed in Table I.1 and 
manufactured in, or imported into, the United States on or after the 
date 5 years after the publication of the final rule for this 
rulemaking.

     Table I.1--Proposed AFUE Energy Conservation Standards for Non-
      Weatherized Gas Furnaces and Mobile Home Gas Furnaces (TSL 3)
------------------------------------------------------------------------
                      Product class                           AFUE %

Non-Weatherized Gas-Fired Furnaces......................              92
Mobile Home Gas-Fired Furnaces..........................              92
------------------------------------------------------------------------

    A number of stakeholders objected to a national standard at 92 
percent AFUE, which would effectively only be able to be met by using 
condensing technology. The objections raised by stakeholders covered a 
wide range of issues, but the negative impacts of the proposed

[[Page 55039]]

standards on some furnace consumers were highlighted by many 
stakeholders.
    A letter dated June 8, 2015, signed by 121 members of the U.S. 
House of Representatives, expressed concern that a nationwide energy 
efficiency standard that effectively precludes a consumer from choosing 
to install a non-condensing furnace would result in many homeowners 
either abandoning the use of natural gas to heat their homes or paying 
substantially more for the installation of a furnace that meets the new 
standard. It stated that many families will be faced with the difficult 
choice of having to replace their non-condensing furnace with either a 
condensing furnace with higher installation costs or electric heat and 
accompanying higher monthly energy bills. (United States House of 
Representatives, No. 67 at p. 1) Comments from the Pennsylvania 
Chambers of Commerce, Business, and Industry, Meeks, Payne, Jr., 
Bishop, Jr., and Carrier make similar statements. (Pennsylvania 
Chambers of Commerce, Business, and Industry, No. 82 at p. 1; Meeks, 
No. 140 at p. 1; Payne, Jr., No. 75 at p. 1; Bishop, Jr., No. 76 at p. 
1)
    The American Gas Association (AGA), Goodman, and American Energy 
Alliance (AEA et al.) stated that even assuming DOE's analysis is 
correct, many consumers could incur costs under the proposed standard. 
They stated that, according to DOE's analysis, 20 percent of households 
nationwide would face higher life-cycle costs under the proposed 
standard, and in the replacement market, one-quarter of all households 
replacing their natural gas furnaces would see a life-cycle cost 
increase. (AGA, No. 118 at p. 27; AEA et al., No. 69 at p. 1; Goodman, 
No. 135 at p. 2) AGA, Goodman, and Southern Gas Association (SGA) added 
that consumers in the South and low-income families would be 
disproportionately impacted. (AGA, No. 118 at p. 27; Goodman, No. 135 
at p. 2; SGA, No. 145 at p. 1)
    The Air-Conditioning, Heating, and Refrigeration Institute (AHRI), 
Carrier, Rheem, and Ingersoll Rand expressed concern that the proposed 
standards will result in 10-20 percent of homes switching from gas 
furnaces to electric heat pumps because venting of a condensing gas 
furnace is difficult to impossible. (AHRI, No. 159 at p. 3; Carrier, 
No. 116 at p. 2; Rheem, No. 142 at p. 3; Ingersoll Rand, No. 156 at p. 
2) AGA expressed a similar concern, and asserted that the resulting 
adverse energy and environmental impacts of this fuel switching are 
very substantial. (AGA, No. 118 at p. 28)
    Several stakeholders, who expressed general support for the 
proposed standards and suggested more stringent standards could be 
justified, provided a recommendation for reducing negative impacts on 
some furnace consumers while maintaining the overall economic and 
environmental benefits of the standards. The American Council for an 
Energy-Efficient Economy (ACEEE) recommended that DOE establish a 
separate product class for small furnaces (tentatively those with an 
input capacity of 50,000 Btu/hour or less) and leave the standard level 
for these units at 80-percent AFUE, while adopting a higher standard 
level of 95-percent AFUE for larger furnaces. (ACEEE, No. 113 at p. 1) 
The Alliance to Save Energy made a similar recommendation, but referred 
to an input capacity of no more than 50,000 to 65,000 Btu/hour for 
smaller furnaces. (Alliance to Save Energy, No. 115 at p. 1) The 
Natural Resources Defense Council (NRDC) urged DOE to adopt an 80-
percent AFUE standard level for furnaces below a specified maximum 
capacity threshold, and set the capacity threshold low enough that the 
national energy, economic, and environmental benefits are largely 
preserved while allowing consumers in small and moderately-sized, well 
insulated and weatherized homes in moderate and warm climates to have a 
non-condensing option. (NRDC, No. 134 at p. 2) AGLR stated that DOE 
should establish a separate product class for small furnaces with an 
input capacity of less than 45,000 Btu/hour, citing section 305(f) of 
EPCA as authority for DOE to establish separate product classes based 
on product capacity. (AGLR, No. 112 at pp. 15-16)
    ACEEE also stated that creating two product classes based on 
furnace size would reduce the number of households that would 
experience net costs under the proposed standard (many of whom are in 
the south). ACEEE stated that many of the consumers who would 
experience net costs will have small furnaces and recommended that DOE 
specifically examine this issue and estimate the economics of separate 
standard levels as a function of furnace input capacity. ACEEE noted 
that a size threshold provides another option for some households with 
very high installation costs--if they weatherize their home and get the 
needed capacity below 50,000 Btu/h, they can avoid the extra 
installation cost of a condensing furnace. ACEEE added that a size 
threshold would not present the potential enforcement challenges 
associated with regional standards. (ACEEE, No. 113 at p. 3)
    Although DOE believes that the standards proposed in the March 2015 
NOPR meet the statutory criteria for amended standards, given the 
concerns and suggestions described above, DOE undertook an analysis of 
the consumer economics and national impacts of establishing separate 
standard levels for large and small residential furnaces. In so doing, 
it examined the effect of alternative size thresholds for a small 
furnace. Because the issues raised by stakeholders primarily concern 
NWGFs, DOE only considered that product in its analysis and did not 
examine mobile home gas furnaces. The analysis is described in section 
II of this NODA; section III provides the results of the analysis.
    DOE notes that this NODA does not propose any energy conservation 
standards for residential furnaces. DOE may revise the analyses 
presented in today's NODA based on any new or updated information or 
data it obtains during the course of the rulemaking. DOE encourages 
stakeholders to provide any additional data or information that may 
improve the analysis.

II. Summary of the Analyses Performed by DOE

    DOE conducted an analysis of the consumer impacts (life-cycle cost 
and payback period) and national impacts (national energy savings and 
net present value of national benefits) of potential standard levels 
for the considered NWGF product classes. The tools used in preparing 
these analyses and their respective results are available at: https://www1.eere.energy.gov/buildings/appliance_standards/rulemaking.aspx?ruleid=62. Each individual spreadsheet includes an 
introduction that provides an overview of the contents of the 
spreadsheet. These spreadsheets present the various inputs and outputs 
to the analysis and, where necessary, instructions. Brief descriptions 
of the analyses and of the supporting spreadsheet tools are provided 
below.
    If DOE were to consider adopting energy conservation standards for 
residential furnaces that set separate levels based on input capacity, 
it would do so in a future supplemental NOPR (SNOPR). DOE would also 
publish a technical support document (TSD) containing a detailed 
written account of the analyses performed in support of the SNOPR, 
which will include updates to the analyses made available in this NODA.
    The analysis conducted for this NODA used the same analytical

[[Page 55040]]

framework as the March 2015 NOPR.\1\ Key aspects of the present 
analysis and DOE's updates to the NOPR analysis are described in the 
sections below.

A. Introduction

    The analysis conducted for this NODA estimated impacts for the 
potential standard level combinations shown in Table II.1. The key 
aspect of this analysis is that only large furnaces would need to use 
condensing technology to meet the standard. Thus, households installing 
a small furnace would not need to incur the costs associated with 
installing a condensing furnace.

    This NODA analysis used the same sample of residential furnace 
consumers as the March 2015 NOPR. Each sample household was assigned a 
furnace size (in terms of input capacity) based on a number of 
features, as discussed in section II.C. The share of households that 
would install a small furnace depends on how ``small furnace'' is 
defined in terms of input capacity. For this analysis, DOE considered 
the following small furnace definitions: <=45 kBtu/hour, <=50 kBtu/
hour, <=55 kBtu/hour, <=60 kBtu/hour, and <=65 kBtu/hour. In each case, 
large furnaces would be defined as all sizes above the given 
thresholds. The share of households that would install a furnace 
meeting a small furnace standard rises as the size cutoff in the small 
furnace definition increases, as illustrated in Table II.2.\2\
---------------------------------------------------------------------------

    \2\ The shares in Table II.2 reflect the likelihood that some 
consumers would down-size a new furnace to meet the ``small 
furnace'' definition. See section II.C for discussion.

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

B. Engineering Analysis

    The engineering analysis establishes the relationship between the 
manufacturer production cost (MPC) and energy efficiency for 
residential furnaces. This relationship between MPC and energy 
efficiency serves as the basis for calculations performed in the other 
analysis tools to estimate the costs and benefits to individual 
consumers, manufacturers, and the nation. For each NWGF efficiency 
level that was analyzed, the MPC was estimated for four furnace 
capacities (60 kBtu/hour, 80 kBtu/hour, 100 kBtu/hour, and 120 kBtu/
hour). For the NODA analysis, DOE updated the MPCs from the NOPR to 
incorporate the most recent available data for material,\3\ component, 
labor, and overhead costs, and also updated the MPCs to 2014$.
---------------------------------------------------------------------------

    \3\ DOE uses 5-year averages for metal materials and current 
prices for all other materials.
---------------------------------------------------------------------------

C. Life-Cycle Cost and Payback Period Analyses

    The life-cycle cost (LCC) and payback period (PBP) analyses 
determine the economic impact of potential standards on individual 
consumers who purchase a furnace in the expected compliance year 
(assumed to be 2021 for this analysis). The LCC is the total cost of 
purchasing, installing and operating a residential furnace over the 
course of its lifetime. DOE determines the LCC by considering: (1) The 
total installed cost to the consumer (which consists of manufacturer 
selling price, distribution channel markups, sales taxes, and 
installation costs); (2) the annual energy consumption (natural gas or 
LPG and electricity) of residential furnaces as they are used in the 
field; (3) the operating cost of residential furnaces (i.e., energy 
cost and maintenance and repair cost); (4) equipment lifetime; and (5) 
a discount rate that reflects the consumer cost of capital and puts the 
LCC in present-value terms. The PBP represents the number of years 
needed to recover the increase in purchase price of higher-efficiency 
residential furnaces through savings in the operating cost.
    For each considered standards case, DOE measures the change in LCC 
relative to a no-new-standards case, which reflects the market in the 
absence of amended energy conservation standards, including market 
trends for equipment that exceeds the current energy conservation 
standards.
    In the March 2015 NOPR and in today's NODA, DOE developed 
nationally-representative household samples for residential furnaces 
from the 2009 Residential Energy Consumption Survey (RECS).\4\ DOE 
analyzed the net effect of potential amended residential furnace 
standards on consumers by calculating the LCC savings and PBP for each 
household by efficiency level.

Administration, Residential Energy Consumption Survey: 2009 RECS 
Survey Data (2013), available at: https://www.eia.gov/consumption/residential/data/2009/ (last accessed July 29, 2015).
---------------------------------------------------------------------------

    DOE performed the LCC and PBP analyses using a spreadsheet model

[[Page 55041]]

combined with Crystal Ball \5\ to account for uncertainty and 
variability among the input variables. Each Monte Carlo simulation 
consists of 10,000 LCC and PBP calculations using input values that are 
either sampled from probability distributions and household samples or 
characterized with single point values. The analytical results include 
a distribution of 10,000 data points showing the range of LCC savings 
for a given efficiency level relative to the no-new-standards case 
efficiency distribution. In performing an iteration of the Monte Carlo 
simulation for a given consumer, product efficiency is chosen based on 
its probability. If the chosen product efficiency is greater than or 
equal to the efficiency of the standard level under consideration, the 
LCC and PBP calculation reveals that a consumer is not impacted by the 
standard level. By accounting for consumers who already purchase more-
efficient products, DOE avoids overstating the potential benefits from 
increasing product efficiency.
---------------------------------------------------------------------------

    \5\ Crystal Ball is a commercial software program developed by 
Oracle and used to conduct stochastic analysis using Monte Carlo 
simulation. A Monte Carlo simulation uses random sampling over many 
iterations of the simulation to obtain a probability distribution of 
results. Certain key inputs to the analysis are defined as 
probability distributions rather than single-point values.
---------------------------------------------------------------------------

1. Furnace Size Assignment
    For the March 2015 NOPR, DOE assigned an input capacity for the 
existing furnace of each housing unit based on an algorithm that 
correlates the heating square footage and the outdoor design 
temperature for heating (i.e., the temperature that is exceeded by the 
30-year minimum average temperature 1 percent of the time) with the 
distribution of input capacity of furnaces.\6\ DOE assumed that, for 
the new furnace installation, the input capacity would remain the same. 
DOE's analysis accounted for the typical over-sizing of furnace 
capacity (i.e., the furnace is larger than it needs to be to fulfill 
the building heating load).
---------------------------------------------------------------------------

    \6\ The distribution of input capacity is based on shipments 
data by input capacity bins for the year 2000 provided by AHRI (AHRI 
(formerly GAMA). Furnace and Boiler Shipments data provided to DOE 
for Furnace and Boiler ANOPR. January 23, 2002). AHRI data was 
further disaggregated into 5-kBtu/h bins using the reduced models 
dataset from the NOPR analysis. Appendix 7B of the NOPR TSD provides 
details about furnace sizing method.
---------------------------------------------------------------------------

    If there is a separate standard for small furnaces, DOE expects 
that some consumers who would otherwise install a typically-oversized 
furnace would choose to down-size in order to be able to purchase a 
non-condensing furnace. For the NODA analysis, DOE identified those 
sample households that might down-size at the considered small furnace 
definitions. DOE first determined if a household would install a non-
condensing furnace with an input capacity greater than the small 
furnace size limit without amended standards. In the standards case, 
DOE assumed that a fraction of such consumers would down-size to the 
input capacity limit for small furnaces.
2. Energy Prices
    For this NODA, DOE updated current energy prices and also the 
projection of future energy prices. Current average and marginal 
monthly energy prices are based on the latest data (2013 energy prices) 
from EIA (Form 861 data \7\ to calculate commercial electricity prices, 
Natural Gas Navigator \8\ to calculate commercial natural gas prices, 
and State Energy Data System \9\ to calculate LPG prices). The update 
to 2013 energy prices had a very small impact on the LCC and PBP 
results.\10\ Future energy prices are based on the projection of 
average annual percent change in national-average residential natural 
gas and electricity prices in the Annual Energy Outlook 2015 (AEO 
2015).

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

3. Other Updates
    For this NODA, DOE updated the efficiency distribution in the no-
new-standards case to reflect AHRI shipments data from 2010 to 
2014.\11\ The update resulted in decreased fraction of consumers being 
impacted by an efficiency standard requiring efficiencies of 90-percent 
AFUE and above.\12\ DOE also made minor updates to the markups, product 
price trend, and the building shell efficiency and climate indexes used 
to adjust energy use. These are described in the LCC spreadsheet.

    \12\ For the NOPR, the AHRI shipments data was not available and 
DOE instead relied on shipments data from the ENERGY STAR program to 
derive its estimates. Based on the AHRI shipments data, DOE's 
estimate of the condensing furnace market share in 2021 increased 
from 47-percent in the NOPR to 53-percent in the NODA.
---------------------------------------------------------------------------

D. National Impact Analysis

    The national impacts analysis (NIA) estimates the national energy 
savings (NES) and the net present value (NPV) of total consumer costs 
and savings expected to result from potential new standards. DOE 
calculated NES and NPV as the difference between a case without amended 
standards and each standards case.
    DOE calculated the annual energy consumption for each case using 
the appropriate per-unit annual energy use data multiplied by the 
projected residential furnaces shipments for each year. To estimate 
impacts of separate standards for small and large furnaces, DOE needed 
to disaggregate NWGF shipments by input capacity. To do so, DOE assumed 
that the shares of each size category in NWGF shipments are the same as 
the shares estimated for the household sample. The shares were assumed 
to remain constant over time.
    Cumulative energy savings are the sum of the annual NES determined 
for the lifetime of furnaces shipped during a 30-year period assumed to 
start in the expected compliance year. Energy savings include the full-
fuel cycle energy savings (i.e., the energy needed to extract, process, 
and deliver primary fuel sources such as coal and natural gas, and the 
conversion and distribution losses of generating electricity from those 
fuel sources).
    To develop the national NPV of consumer benefits from potential 
energy conservation standards, DOE calculated projected annual 
operating costs (energy costs and repair and maintenance costs) and 
annual installation costs for the no-new-standards case and the 
standards cases. DOE calculated annual energy expenditures from annual 
energy consumption using forecasted energy prices in each year. DOE 
calculated annual product expenditures by multiplying the price per 
unit times the projected shipments in each year.
    The aggregate difference each year between operating cost savings 
and increased installation costs is the net savings or net costs. DOE 
multiplies the net savings in future years by a discount factor to 
determine their present value. DOE estimates the NPV of consumer 
benefits using both a 3-percent and a 7-percent real discount rate, in 
accordance with guidance provided by the Office of Management and 
Budget (OMB) to Federal agencies on the development of regulatory 
analysis.\13\

    For the NODA analysis, DOE updated energy price trends and several 
other inputs with data from AEO 2015, as described in the NIA 
spreadsheet.

III. Results of the Analysis

A. Economic Impacts on Consumers

    As mentioned in section II.C, for each considered standards case, 
DOE measures the change in LCC relative to a no-new-standards case. For 
example, in the case of a separate standard of 90-percent AFUE for 
large furnaces and 80-percent AFUE for small furnaces, the analysis 
reflects the likelihood that some consumers would purchase a furnace at 
or above those efficiency levels without standards, and thus would not 
be affected by the standards. The average LCC savings in Table III.1 
only include those consumers who would be affected at a given standard 
level.
    Table III.2 shows the percentage of consumers that would experience 
a net cost under each considered standards case, and Table III.3 shows 
the percentage of consumers in the South that would experience a net 
cost.\14\ For these consumers, the LCC would increase under the 
standard compared to the furnace they would purchase in no-new-
standards case. As expected, the percentage of consumers that would 
experience a net cost declines as the definition of small furnace 
expands to include more furnaces.
---------------------------------------------------------------------------

    \14\ The analysis used the same definition of the South region 
as the March 2015 NOPR.

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

    Table III.4 compares the key consumer economic impacts of a single 
standard for all furnaces to a separate standard for large and small 
furnaces.\15\ Under a separate standard for large and small furnaces, 
the average LCC savings increase somewhat but the share of consumers 
with a net cost declines considerably. The impacts of a separate 
standard for large and small furnaces would vary depending on the small 
furnace definition. For example, if the definition was <=60 kBtu/hour 
instead of <=55 kBtu/hour, the difference between the single standard 
for all furnaces and separate standards for large and small furnaces 
would be greater than shown.
---------------------------------------------------------------------------

    \15\ The results for a single standard for all furnaces differ 
slightly from the results in the March 2015 NOPR because of the 
input revisions discussed in section II. DOE believes that showing a 
direct comparison with the NOPR results would not serve the purpose 
of the NODA analysis.

* Using small furnace definition of <=55 kBtu/hour.

    Table III.5 and Table III.6 show a similar comparison for consumers 
in the south and low-income consumers, with similar results.\16\
---------------------------------------------------------------------------

    \16\ The results in Table III.6 overstate the percentage of low-
income households that would actually be negatively impacted by 
proposed higher-efficiency furnace standards. Close to 60 percent of 
low-income households in RECS 2009 are either renters or residents 
of public housing. In these cases, the furnace would be purchased by 
the property owner, and the cost of a higher-efficiency furnace 
might be passed on over time in the rent (or perhaps not all in the 
case of public housing). DOE's current analysis assumes that in 
cases where the property owner does not pay for energy, the cost of 
a higher-efficiency furnace is passed on immediately, which would 
tend to overstate any negative impact.

    In the NOPR analysis, DOE estimated that some consumers faced with 
significant costs to install a condensing furnace would instead choose 
to switch to electric heating with a heat pump or electric furnace. If 
there were a separate, lower standard level for small furnaces, fewer 
consumers would be faced with installing a condensing furnace, and 
there would be less switching. Table III.7 shows this outcome.

B. National Impacts

    The estimated national energy savings (full-fuel-cycle) of the 
considered combinations of minimum AFUE for large and small furnaces 
are shown in Table III.8.
    Table III.9 and Table III.10 show the national NPV of benefits for 
alternative furnace standard level combinations at 7-percent and 3-
percent discount rates, respectively. The national energy savings 
decrease as the small furnace definition expands.

    Table III.11 compares the national energy savings and NPV of a 
single standard for all furnaces vs. a separate standard for large and 
small furnaces. The national energy savings are higher in the case of a 
separate standard for large and small furnaces mainly because there is 
less switching from gas to electric heating.\17\ The NPV is higher in 
the case of a separate standard for large and small furnaces mainly 
because the LCC savings are higher. The impacts of a separate standard 
for large and small furnaces would vary depending on the small furnace 
definition.
---------------------------------------------------------------------------

    \17\ In terms of FFC energy, switching from gas to electricity 
increases energy use considerably because of the losses in thermal 
electricity generation.
