INTRODUCTION TO SUPPLE:MENTAL ANALYSIS FOR RANGIES AND OVENS I - 

The previous analysis of ranges and ovens1 has been revised based on more current information 

concerning the penetration of self-cleaning ovens and of gas cooking products without pilot 

lights. Additionally, two more recent fbel price forecasts ( AEO (Annual Energy Outlook) 97 and 

GRI (Gas Research Institute) 97) have been employed in the revised analysis. Supplemental 

Chapter 4, which follows this introduction, contains the revised life-cycle cost (LCC) and payback 

peribd analyses. Supplemental Chapter 3 contains the revised projected national impacts of 

several trial standard levels. Environmental impacts of one trial standard level (level 3A) are also 

shown. 

One of the design options evaluated in Chapter 4 for gas cooking products is substitution of a 

standiig pilot light with an electric or electronic ignition. There are some households with gas 

cooking products that do not have an electrical wall outlet near their kitcheh range. Therefore, 

We-cycle cost analyses have been performed under two diierent installation cost scenarios. These 

- are: no installation cost for homes with an available electrical outlet in the kitchen and a $90 

installation cost for those homes requiring an outlet. LCCs are also determined by calculating a 

weighted average from the $0 and $90 cases. Assuming that 20% of households require 

installation of an electrical outlet (a conservative assumption ,see Chapter 4.1.1) the weighted 

LCC is determined by multiplying the the LCC from the $90 case by 20% and the LCC from the 

$0 case by 80%. 

Supplemental chapter 3 contains revised energy consumption and net present value (NPV) results 

for four trial standard levels for cooktops and ovens. There are three base case scenarios 

analyzed: AEO 1995, AEO 1997 and GRI 1997. Details of those three &el price scenarios are 

described in supplemental Chapter 3. Also shown are shipment forecasts of cooktops and ovens.

INTRODUCTION TO SUPPLEMENTAL ANALYSIS FOR RANGES AND OVENS 

The previous analysis of fanges and ovens1 has been revised based on more ~ent information 

C()nceming the penetration of self-cleaning ovens and of gas cooking products without pilot 

lights. Additionally, two more recent fuel price forecasts ( AEO (Annual Energy Outlook) 97 and 

GRI (Gas Research Institute) 97) have been employed in the revised analysis. Supplemental 

Chapter 4, which follows this introduction, contains the revised life-cycle cost (LCC) and payback 

period analyses. Supplemental Chapter 3 contains the revised projected national impacts of 

several trial standard levels. Environmental impacts of one trial standard level (level 3A) are also 

shown. 

One of the design options evaluated in Chapter 4 for gas cooking products is substitution of a 

standing pilot light with an electric or electronic ignition. There are some households with gas 

cooking products that do not have an electrical wall outlet near their kitche~ range. Therefore, 

life-cycle cost analyses have been performed under two different installation cost scenarios. These 

. are: no installation cost for homes with an available electrical outlet in the kitchen and a S90 

installation cost for those homes requiring an outlet. LCCs are also determined by calculating a 

weighted average from the SO and S90 cases. Assuming that 20010 of households require 

installation of an electrical outlet (a conservative assumption ,see Chapter 4.1.1) the weighted 

LCe is determined by multiplying the the LCC from the S90 case by 20010 and the LCC from, the 

SO case by 80010. 

Supplemental chapter 3 contains revised energy consumption and net present value (NPV) results 

for four trial standard levels for cooktops and ovens. There ar~ three base case scenarios 

analyzed: AEO 1995, AEO 1997 and GRI 1997. Details of those three fuel price scenarios are 

described in supplemental Chapter 3. Also shown are shipment forecasts of cOoktops and ovens.

SUPPLEMENTAL CHAPTER 3. PROJECTED NATIONAL IMPACTS OF 

STANDARD LEnLS: KITCHEN RANGES AND OVENS 

The LBNL Residential Energy Model (LBNL-REM) projects a number of economic and 

energy-use variables that are used to assess the impact of proposed standard levels on consumers, 

electric utilities, and appliance manufacturers. This chapter presents projections from the model, 

which assume various standard levels. 

The principal outputs from the LBNL-REM for each year are: 

unit equipment price and operating expense by product, 

projected annual shipments of residential appliances, 

b energy consumption by end use and fuel, and 

differences in these quantities between a base case and each energy efficiency level. 

These outputs are calculated for each year and accumulated over the time period from 2001 

to 2030. Energy savings are given for each year from implementation of standard levels to the end 

of the period. Net present value of the standard levels is evaluated for each regulated product and 

for the end use(s) comprising the regulated and competing products. The analysis is done for three 

separate scenarios, based on different sets of fuel price projections and housing forecasts. The three 

scenarios are (1) fuel price and housing forecasts based on the AEO 199S1, (2) fuel price and housing 

forecasts based on the AEO 19972 and (3) fuel price forecasts from the GRI 1997' and housing 

forecasts from AEO 1997. Supplemental Table 3.1 shows a comparison of the three fuel price 

projections.

3.2 ENERGY CONSUMPTION 

In order to project the effect on energy savings if pilot lights were not allowed on gas ranges and 

ovens, it is necessary to determine how many ranges, cooktops and ovens are built with pilot lights 

now and how many will be built with pilot lights in the future when no new standards are enacted. 

Similarly, the future projections of ovens having a self-cleaning feature has to be estimated. 

Ranges have both cooktops and ovens. Surface cooktops are those sold separately without an 

oven. Built-ins refer to ovens that are built into cabinetry and refer only to ovens. 

Data on ranges, ovens, and cooktops were obtained from two data sources. The first source is the 

AHAM Fact Book4, excerpt shown in Supplemental Table 3.3, which gives the break down of 

shipments from 1986 to 1996 of free standing ranges, built-in's and surface cooktops. The second 

source, as shown in Supplemental Tables 3.4 and 3.5 is data supplied to the Department from 

AHAM. The data contain information on the percentages of shipment of gas ranges and gas ovens

In order to estimate the average energy use of new cooktops and ovens, weighted-averages 

are calculated by taking the product of the UEC for each class times class-specific weighting factors, 

and then summing over the classes. Gas cooktops are separated into two classes, namely range 

cooktops and surface cooktops. This enables different rates of penetration of electronic ignition to 

be modeled separately for the two categories. The historical percentages of gas range cooktops versus 

gas surface cooktops are based on data from AHAM (see Supplemental Table 3.3). From 1997 on, 

gas range cooktops are then assumed to take up 89% of the market while gas surface cooktops are 

assumed to take up 1 1 %. 

Supplemental Table 3.5 Percent of Electric and Gas Oven with Self-Cleaning 

Similarly, gas non-self-cleaning ovens are also broken into range ovens and built-in ovens 

to allow separate projections of the displacement of standing pilots. However, this distinction is not 

done for gas self-cleaning ovens because all gas self-cleaning ovens are assumed to be without 

standing pilots. This results in three classes of gas ovens, namely, 1) non-self-cleaning range ovens, 

2) non-self-cleaning built-in ovens and 3) self-cleaning ovens. The historical percentages for the 

three classes of gas ovens are calculated using data from AHAM as given in Supplemental Tables 

3.3,3.4 and 3.5. Projections of future percentages are estimated using regressions on the historical 

data. Supplemental Tables 3.6 and 3.7 show the percentages, or weighting factors, for cooktops and 

ovens.

Supplemental Tables 3.9a to 3.12a show the past and projected average energy use of new 

cooktops and ovens for the AEO 1995 case. Supplemental Tables 3.9b to 3.12b and Supplemental 

Tables 3.9~ to3.12~ show the same information for the AEO 1997 and GRI 1997 cases respectively. 

The UEC of electric cooktops is projected to stay constant over the analysis period. The UEC of gas 

cooktops is projected to decrease due to the displacement of standing pilots by electronic ignition. 

The UEC of electric ovens increases as more self-cleaning units are expected to enter the market. 

The UEC of gas ovens decreases because of the move towards electronic ignition for the non selfcleaning ovens and the increased penetration of the self-cleaning units which do not have pilot lights. 

The UEC of cooktops and ovens are the same in the base case for the three scenarios except 

in the case of electric cooktops. For the AEO 1995 case, which has a positive growth in electricity 

price, the LBNL-REM model forecasts a decrease in UEC for electric cooktops after 2010, while it 

remains constant in the two other scenarios. 

Supplemental Tables 3.13a to 3.18a show the national energy consumption for cooktops and 

ovens for the AEO 1995 case. Supplemental Tables 3.13b to 3.1% and 3.13~ to 3.18~ show the same 

results for the AEO 1997 and GRI 1997 cases respectively. The conversion from kwh to primary 

energy is 1 1500 Btu per kwh.

Projections of the purchase prices for new cooktops and ovens in 1990 dollars are shown in 

Supplemental Tables 3.21a to 3.24a for the AEO 1995 case, Supplemental Tables 3.21b to 3.24b for 

the AEO 1997 case, and Supplemental Tables 3.21~ to 3.24~ for the GRI 1997 case. The purchase 

prices of cooktops and ovens are the same in the base case for the three scenarios except in the case 

of electric cooktops. For the AEO 1995 case, which shows a positive growth in electricity price, the 

LBNL-REM model forecasts an increase in average efficiency for electric cooktops after 2010, thus 

results in an increase in purchase price.

3.5 NET PRESENT VALUE 

The net present value (NPV) of standards for cooktops and ovens is calculated by first 

determining the difference in present value of unit life-cycle costs between the base case and 

standards case each year. That difference is then multiplied by the standards case shipments for the 

year. The NPV for the period (2001-2030) is the sum over the years of the annual values. A positive 

NPV of standards results when the new units in the standards case have lower present value of 

life-cycle cost than do new units in the base case. Supplemental Tables 3.25a through 3.30a show 

the NPV to society of the standards levels for the AEO 1995 case. Supplemental Tables 3.25b 

through 3.30b show the NPV for the AEO 1997 case while Supplemental Tables 3.25~ to 3.30~ show 

the results for the GRI 1997 case.

3.6 SENSITIVITY ANALYSIS 

The base case and standards levels as described above constitute a reference case against 

which the impacts of standards under different assumptions may be compared. The sensitivity 

analysis is performed by running the LBNL-RE?M for the base case and a combined standards case 

that includes standards level 3A for cooktops and oven. For each sensitivity case, the results for 

standards level 3A are compared to the corresponding base-case run and the differences are 

tabulated. The runs are based on the fuel price projections and housing forecasts from the AEO 1997. 

The sensitivity cases selected are defined as follows: 

1. Lower Equipment Price. The price of the baseline unit and the incremental price associated 

with each engineering level is decreased by the estimated uncertainty interval. 

2. Higher Equipment Price. The price of the baseline unit and the incremental price associated 

with each engineering level is increased by the estimated uncertainty interval. 

3. High Equipment Eficiency. The average efficiency is assumed to improve at a rate of 2% a 

year starting from year 2001 until the most efficient designs are achieved. 

Supplemental Tables 3.31a through 3.31d show the unit energy consumption of cooktops and 

ovens for the three sensitivity cases. Supplemental Tables 3.22a to 3.22b show results for cumulative 

energy consumption. The sensitivity analysis of product shipments is given in Supplemental Tables 

3.33a and 3.33b. Supplemental Tables 3.34a and 3.34b show the net present values of the reference 

and the sensitivity cases.

INTRODUCTION TO SUPPLEMENTAL ANALYSIS FOR RANGES AND OVENS 

The previous analysis of ranges and ovens1 Has been revised based on more current information 

concerning the penetration of self-cleaning ovens and of gas cooking products without pilot 

lights. Additionally, two more recent fuel price forecasts ( AEO (Annual Energy Outlook) 97 and 

GRI (Gas Research Institute) 97) have been employed in the revised analysis. Supplemental 

Chapter 4, which follows this introduction, contains the revised life-cycle cost (LCC) and 

payback period analyses. Supplemental Chapter 3 contains the revised projected national impacts 

of several trial standard levels. Environmental impacts of one trial standard level (level 3A) are 

also shown. 

One of the design options evaluated in Chapter 4 for gas cooking products is substitution of a 

standing pilot light with an electric or electronic ignition. There are some households with gas 

cooking products that do not have an electrical wall outlet near their kitchen range. Therefore, 

life-cycle cost analyses have been performed under two different installation cost scenarios. 

These are: no installation cost for homes with an available electrical outlet in the kitchen and a 

$90 installation cost for those homes requiring an outlet. LCCs are also determined by 

calculating a weighted average from the $0 and $90 cases. Assuming that 20% of households 

require installation of an electrical outlet (a conservative assumption ,see Chapter 4.1.1) the 

weighted LCC is determined by multiplying the the LCC from the $90 case by 20% and the LCC 

from the $0 case by 80%. 

Supplemental chapter 3 contains revised energy consumption and net present value (NPV) results 

for four trial standard levels for cooktops and ovens. There are three base case scenarios 

analyzed: AEO 1995, AEO 1997 and GRI 1997. Details of those three fuel price scenarios are 

described in supplemental Chapter 3. Also shown are shipment forecasts of cooktops and ovens.

1 Draft Report on Potential Impact of Alternative Efficiency Levels for Residential Cooking Products, 

Lawrence Berkeley National Laboratory, April, 1996 
SUPPLEMENTAL CHAPTER 4: LIFE-CYCLE COSTS 

AND PAYBACK PERIOIIS 

The effect of standard levels on inhvidual consumers includes a change in operating expense 

(usually a decrease) and a change in purchase price (usually an increase). The net effect is analyzed 

by calculating the life-cycle cost and payback period, using engineering data for energy consumption 

and equipment price from an earlier Draft Report on residential cooking products', and estimating 

an energy price for the year in which new efficiency standards are assumed to take effect (i.e., the 

year 2001). 

The following tables present the life-cycle costs (LCC) and payback periods (PBP) of design 

options analyzed for the following classes of residential cooking products: 1) electric non-self 

cleaning ovens, 2) gas cooktops, 3) gas non-self cleaning ovens, and 4) gas non-self cleaning ranges 

(i.e., a cooking appliance consisting of a cooktop and a non-self cleaning oven). The earlier Draft 

Report on residential cooking products demonstrated that the first three standard levels for the above 

classes of cooking products require more in-depth analysis to determine whether they are costeffective under different circumstances for improving energy efficiency. For electric non-self 

cleaning electric ovens, the first three standard levels cover the following design options: reduced 

vent rate, improved insulation, and improved seals. For gas cooking products, standard levels one 

and two represent the baseline model while standard level three represents the baseline model with 

either an electric or electronic ignition device. 

4.1 LIFE-CYCLE COST 

The LCC is the sum of the installed consumer cost (ICC) and the present value of operating 

expenses (OE) discounted over the lifetime (N) of the appliance. 

OEt 

LCC = ICC + C 

t=i (1 + r)' 

If operating expenses are constant over time, Eq. 4.1 simplifies to: 

LCC = ICC + PWF-OE,

an earlier report on kitchen ranges and ovens entitled Draft Report on Potential Impact of Alternative Eficiency Levels 

for Residential Cooking Products, April 1996, prepared by Lawrence Berkeley National Laboratory for the U.S.

SUPPLEMENTAL CHAPTER 4: LIFE-CYCLE COSTS 

AND PAYBACK PERIODS 

The effect of standard levels on individual consumers includes a change in operating expense 

(usually a decrease) and a change in purchase price (usually an increase). The net effect is analyzed 

by calculating the life-cycle cost and payback period, using engineering data for energy consumption 

and equipment price from an earlier Draft Report on residential cooking products 1

, and estimating 

an energy price for the year in which new efficiency standards are assumed to take effect (i.e., the 

year 2001). 

The following tables present the life-cycle costs (Lee) and payback periods (PBP) of design 

options analyzed for the following classes of residential cooking products: 1) electric non-self 

cleaning ovens, 2) gas cooktops, 3) gas non-self cleaning ovens, and 4) gas non-self cleaning ranges 

(i.e., a cooking appliance consisting of a cooktop and a non-self cleaning oven). The earlier Draft

and two represent the baseline model while standard level three represents the baseline model with 

either an electric or electronic ignition device.

where the present worth factor is defined as: 

The LCC is calculated for each class in the year levels are set, using a discount rate, r. 

The installed consumer cost (ICC) is composed of a retail price-based on factory costs, 

factory, distributor, and retail markups-plus installation costs (where applicable). For the gas 

cooking appliances considered here, only a single design option, an electric or electronic ignition 

device, is assumed to incur an increase in installation cost. In the case of electric non-self cleaning 

ovens, it is assumed that none of the design options considered cause an increase in the installation 

cost. A more complete discussion of the impact on installation cost due to electric and electronic 

ignition devices for gas cooking products will follow. 

Operating expenses (OE) include energy expenditures and maintenance costs. Annual energy 

consumption is the average unit energy consumption in thefield (from LBNL-EM). Annual energy 

expense to the consumer is annual energy consumption times energy price. Annual energy 

consumption values are discussed in detail in Appendix A of the earlier Draft Report on residential 

cooking products. Energy price is the projected average residential energy price for the year 2001 

multiplied by an end-use factor of 1.04 for electric and 1.1 1 for gas, both derived from DOEEIA's 

1990 Residential Energy Consumption Survey. Annual operating expenses are discounted to the 

year of purchase (2001) and summed over the average life of the product to obtain a present value. 

For the residential sector, the discount rate is 6% real, with sensitivity analyses performed at 2% and 

15% real. 

4.1.1 Installation Costs-Electric and Electronic Ignition Devices 

For the gas cooking appliances considered here, all baseline models are assumed to utilize 

standing pilot ignition devices. Electronic and/or electric ignition devices are a means in which to 

eliminate the need for standing pilots and reduce overall energy consumption. But for those 

households which currently use gas cooking appliances with standing pilot ignition devices and do 

not have electrical wall outlets installed in the kitchen, the purchase of a new gas cooking product 

with an electric and/or electronic ignition device would require the installation of an electrical wall 

outlet.

The installation cost of adding an electrical wall outlet to a kitchen was assumed to be $90 

(in 1990 dollars) based on information from the Gas Research Institute3. The $90 value was 

substantiated with data from the R.S. Means Repair & Remodeling Cost Data4. Depending on the 

outlet type, cable type, and amp service, the total installation cost including overhead and profit 

ranges from $35.50 to $107. Values exceeding $90 in the R.S. Means Cost Data are based on the 

use of EMT conduit, whose use is very unlikely for the installation of kitchen wall outlets. Also of 

note, ground fault interrupt (GFI) type outlets were not considered. According to the 1996 National 

Electrical Code, article 210-8A6, GFI electrical wall outlets are required in kitchens only where the 

receptacles are installed to provide electricity to counter top services. 

The exact number of households that would require the installation of an electrical wall outlet 

is unknown. But two surveys, the 1990 Residential Energy Consumption Survey (RECS)' and the 

1993 American Housing survey6, were used to estimate the upper bound on the number of 

households which do not have electrical wall outlets in the kitchen. Refrigerator saturations from 

RECS were used to estimate the number of households that do not have an electrical wall outlet. The 

idea being that if a household has a refrigerator than it must have an electrical outlet in the kitchen 

as well. Supplemental Table 4.1 shows refrigerator saturations and housing stocks as reported by 

RECS.

The exact number of households that would require the installation of an electrical wall outlet 

is unknown. But two surveys, the 1990 Residential Energy Consumption Survey (RECS)s and the 

1993 American Housing Survey6, were used to estimate the upper bound on the number of 

households which do not have electrical wall outlets in the kitchen. Refrigerator saturations from 

RECS were used to estimate the number of households that do not have an electrical wall outlet. The 

idea being that if a household has a refrigerator than it must have an electrical outlet in the kitchen 

as well. Supplemental Table 4.1 shows refrigerator saturations and housing stocks as reported by 

RECS.

refrigerators. It is assumed that almost all of these households have no electrical outlets in the 

kitchen. According to the American Housing Survey, 2.03% of U.S. households in 1993 did not 

have a working electrical outlet in every room. Using RECS housing statistics, this means that 

approximately 1.9 million U.S. households, according to the American Housing Survey, did not have 

a working electrical outlet in every room. It is likely that based on the RECS and American Housing 

Survey data, the number of households without electrical outlets in the kitchen is some where 

between 250 thousand and 1.9 million. 

Due to the uncertainty regarding the number of households that might require an electrical 

wall outlet to accommodate the use of a gas cooking product with electric or electronic ignition, 

three installation cost scenarios are analyzed: 1) no installation cost for those homes with an existing 

outlet in the kitchen, 2) a $90 installation cost for those homes requiring an outlet, and 3) an $18 

installation cost based on the conservative assumption that 20% of households would require an 

outlet. In the case of the $18 installation cost scenario, LCCs are determined by calculating a 

weighted average value from the $0 and $90 cases. Specifically, the LCC for any single design 

option under the $1 8 case is determined by multiplying the corresponding'LCC for the $90 case by 

20% and adding to it the corresponding LCC for the $0 case multiplied by 80%. 

4.1.2 Fuel Price Projections 

For the LCC analysis, three different fuel price projections were used in order to encompass 

the full range of fuel price estimates. The three fuel price scenarios are based on projections from 

the DOES/EIA 1995 Annual Energy Outlook7, the DOE/EIA 1997 Annual Energy Outlooks, and the 

Gas Research Institute (GRI) 1997 Edition ofthe Baseline Projection Data Book9. Supplemental 

Table 4.2 provides the fuel prices projected from each of the above three sources for the year 2001. 

(The year 2001 is assumed to be the effective date of any new standard.) As discussed earlier, fuel 

prices incorporating end-use multipliers (1.1 1 for gas and 1.04 for electric) are used in the analysis.

4.1.4.2 LCC Results for Gas Non-Self Cleaning Ovens 

Supplemental Tables 4.16 through 4.24 show the LCCs by design option for gas non-self 

cleaning ovens. In addition to the first three standard levels consisting of the baseline model and 

electric ignition, the the LCC for electronic ignition is also shown. Thus, a direct comparison can 

be made between electric and electronic ignition. Nine tables are presented showing how LCC is 

impacted by the three different installation cost scenarios and the three different fuel price 

projections. Under all three different fuel price projections, electric ignition (standard level three) 

is shown to have the least LCC for the $0 installation cost scenario. Electric ignition also has the 

least LCC under the $18 installation cost scenario except for LCCs calculated with a discount rate 

of 15% using I997 AEO and 1997 GRI fuel price projections. Under the $90 installation cost 

scenario, the baseline model (standard levels one and two) has the least LCC regardless of the fuel 

price projection.

4.1,4.3 LCC Results for Gas Ranges 

Ld 

Supplemental Tables 4.25 through 4.33 show the LCCs and simple payback periods by 

design option for gas non-self cleaning ranges (i.e. a gas cooking appliance consisting of a cooktop 

and a non-self cleaning oven). The LCC analysis for gas ranges was conducted by constructing 

energy use and consumer cost data from the gas cooktop and gas non-self cleaning oven data sets. 

For example, in the case of the gas range baseline model, annual energy use, installed consumer cost, 

and annual operating expense are constructed by adding the respective values from the baseline 

models for gas cooktops and gas non-self cleaning ovens. For each of the nine possible 

combinations of fuel price and installation cost, the gas cooktop and gas non-self cleaning oven data 

sets are presented along with the constructed data for the gas range. 

In constructing the data for the gas range, two design paths were considered: one path where 

an electronic ignition device is used by the cooktop and an electric glo-bar ignition device is used 

by the oven and another path where both the cooktop and oven utilize electronic ignition. For the 

cases where the cost of an electrical wall outlet is considered, installation cost savings are realized 

for both of the above design paths. This is due to the situation that only one outlet is necessary for 

a gas range requiring electricity as opposed to the two outlets required when the individual 

components are analyzed separately. In the design path case where electronic ignition is utilized by 

both the cooktop and oven, factory cost and maintenance cost savings are realized as only a single 

control module is necessary for the gas range as opposed to the two control modules required when 

the individual components are analyzed separately. 

k 

Supplemental Tables 4.25 through 4.33 demonstrate how LCCs are impacted by the three 

different installation cost scenarios and the three different fuel price projections. In all nine cases, 

the gas range design path where electronic ignition is utilized by both of the individual components 

incurs the lowest LCCs. This is due to the factory cost and resulting retail price savings realized by 

requiring only one set of ignition controls. At a discount rate of 6%, the electronic ignition design 

option has a lower LCC than the baseline model for all installation cost and fuel price projection 

scenarios.

4.2 LCC SENSITIVITY ANALYSIS 

The national LCC results in Supplemental Section 4.1 were tested for sensitivity by varying 

assumptions about energy prices for each product class. The results of this analysis should be 

compared to the LCC tables in Supplemental Section 4.1. 

Low and high energy prices were defined as the minimum and maximum, respectively, of 

states' energy prices. State energy prices were taken from the Energy Information Administration's 

State Energy Price and Expenditure Report 19941°. The latest year for which energy prices are 

reported is 1994. Low and high natural gas and electricity prices with and without energy price enduse factors of 1.04 for electric and 1.11 for gas are reported in Supplemental Table 4.34. 

Supplemental Tables 4.35 through 4.38 summarize the results of the energy price sensitivity 

analysis for each of the four product classes analyzed here. For the gas cooking appliances, the low 

and high energy prices are used to determine LCCs for only the $0 and $90 installation cost 

scenarios. In Supplemental Tables 4.35 through 4.38, the LCC reference cases based on the 1995 

AEO, 1997 AEO, and the 1997 GRI fuel price projections are provided.

4.3 STANDARD LEVEL IMPACTS ON LIFIE-CYCLE COST DImRENCES, PAYBACK 

PERIODS, AND COST OF CONSERVED ENERGY 

Standard levels correspond to a set of design options. For the four classes of residential 

cooking products being analyzed here, the previous LCC tables indicate which design option or set 

of design options correspond to a particular standard or efficiency level. There are five standard 

levels considered for each residential cooking product class. In addition to the previous tables 

demonstrating how a particular standard level affects LCC, the impact of standard levels is further 

assessed by calculating life-cycle cost (LCC) differences, payback periods (PBP), and cost of 

conserved energy (CCE). 

1995 1997 1997 Prices Prices 

$1129 $1076 $1099 $948 $1810 

The LCC difference is determined by subtracting the LCC for the standards case from the 

LCC for the base case. If the LCC difference is greater than zero (positive savings), the standard 

level provides a net decrease in expenses to the consumer. That is, the present value of decreased 

operating expenses offsets the increased purchase price. Conversely, if the LCC difference is 

negative, the efficiency level causes a net increase in expenses to the consumer.

4.3 STANDARD LEVEL IMPACTS ON LIFE-CYCLE COST DIFFERENCES, PAYBACK 

PERIODS, AND COST OF CONSERVED ENERGY 

Standard levels correspond to a set of design options. For the four classes of residential 

cooking products being analyzed here, the previous LCC tables indicate which design option or set 

of design options correspond to a particular standard or efficiency level. There are five standard 

levels considered for each residential cooking product class. In addition to the previous tables 

demonstrating how a particular standard level affects LCC, the impact of standard levels is further 

assessed by calculating life-cycle cost (LCC) differences, payback periods (PBP), and cost of 

conserved energy (CCE). 

The LCC difference is determined by subtracting the LCC for the standards case from the 

LCC for the base case. If the LCC difference is greater than zero (positive savings), the standard 

level provides a net decrease in expenses to the consumer. That is, the present value of decreased 

operating expenses offsets the increased purchase price. Conversely, if the LCC difference is 

negative, the efficiency level causes a net increase in expenses to the consumer. 

4-19 
The payback period (PBP) measures the amount of time needed to recover the additional 

consumer investment in increased efficiency through lower operating costs. PBP is found by solving 

the equation: 

PBP 

APC + AOC, = 0 

t=l 

for PBP, where PC=purchase price and OC=operating cost. In general, PBP is found by 

interpolating between the two years when the above expression changes sign. If the operating cost 

is constant, the equation has the simple solution: 

APC PBP = -- 

AOC 

Numerically, the PBP is the ratio of the increase in purchase (and installation) price from the base 

to the efficiency levels cases to the decrease in annual operating expenditures (including 

maintenance). PBPs are expressed in years. A PBP of three years means that the increased purchase 

price is equal to three times the value of reduced operating expenses achieved in the year of 

purchase, or that the increased purchase price is recovered in approximately three years because of 

lower operating expenses. PPBs greater than the life of the product mean that the increased purchase 

price is not recovered in reduced operating expenses. 

The cost of conserved energy (CCE) is the increase in purchase price amortized over the 

lifetime of the appliance at the consumer discount rate divided by the annual energy savings: 

CCE = - 

CRF. APC 

AE 7 

where the capital recovery factor (CRF = 1PWn is used to annualize the capital costs. Note that 

although the CCE can be measured in cents per kwh, it does not depend on current or future energy 

prices. The consumer will benefit whenever the cost of conserved energy is less than the price of 

energy for that end use. 

Supplemental Tables 4.37 through 4.57 show the calculation of LCC differences, PBP, and 

CCE. The tables showing the calculation of LCC differences, PBPs, and CCEs are composed of 

several parts. Part "a" summarizes for each design option the installed consumer cost, annual energy 

use, and operating expense; LCC (at 6% consumer discount rate); and the distribution of units sold 

in 2001, according to the base case forecast as determined by LBNL-REM. Part "b" applies the 

weights from the distributions listed in the last column of part "a" to the values in each preceding 

column in order to obtain weighted average values. Finally, Part "c" shows the resulting LCC 

EE-RM-S-97-700_EERE-1997-STD-0070_COMMENT 07

The payback period (PBP) measures the amount of time needed to recover the additional 

consumer investment in increased efficiency through lower operating costs. PBP is found by solving 

the equation: 

PBP 

.dPC + L .dOC1 = 0 (4.4) 

1=1 

for PBP, where PC=purchase price and OC=operating cost. In general, PBP is found by 

interpolating between the two years when the above expression changes sign. If the operating cost 

is constant, the equation has the simple solution: 

PBP = 

.dOC (4.5) 

Numerically, the PBP is the ratio of the increase in purchase (and installation) price from the base 

to the efficiency levels cases to the decrease in annual operating expenditures (including 

maintenance). PBPs are expressed in years. A PBP of three years means that the increased purchase 

price is equal to three times the value of reduced operating expenses achieved in the year of 

purchase, or that the increased purchase price is recovered in approximately three years because of 

lower operating expenses. PPBs greater than the life of the product mean that the increased purchase 

price is not recovered in reduced operating expenses. 

The cost of conserved energy (CCE) is the increase in purchase price amortized over the 

lifetime of the appliance at the consumer discount rate divided by the annual energy savings: 

CCE = (4.6) 

where the capital recovery factor (CRF = lIPWF) is used to annualize the capital costs. Note that 

although the CCE can be measured in cents per kWh, it does not depend on current or future energy 

prices. The consumer will benefit whenever the cost of conserved energy is less than the price of 

energy for that end use. 

Supplemental Tables 4.37 through 4.57 show the calculation of LCC differences, PBP, and 

CCE. The tables showing the calculation of LCC differences, PBPs, and CCEs are composed of 

several parts. Part "a" summarizes for each design option the installed consumer cost, annual energy 

use, and operating expense; LCC (at 6% consumer discount rate); and the distribution of units sold 

in 2001, according to the base case forecast as determined by LBNL-REM. Part "b" applies the 

weights from the distributions listed in the last column of part "a" to the values in each preceding 

column in order to obtain weighted average values. Finally, Part "c" shows the resulting LCC 

4-20 
differences, PBPs, and CCE. In Part "c", PBPs are presented which are based upon energy use data 

determined both from the proposed DOE test procedure and recent field measurements. As 

discussed in the earlier Drafr Report on residential cooking products, recent field data indicate that 

the annual energy use of ovens and cooktops is approximately 12-17% lower than that determined 

with proposed DOE test procedure calculations. Because the field data indicate lower energy use, 

"field-based" PBPs are typically greater than those determined with the proposed test procedure. 

4.3.1 Data Inputs for Calculating LCC Differences, PBPs, and CCEs 

The data required for calculating LCC differences, PBPs, and CCEs have been discussed 

previously. In addition, the calculation requires that a distribution of design options is projected (by 

LBNL-EM) for the base case. Only those designs that are eliminated by the standard level are 

included in the calculation of impacts. Consumers whose base case choice is eliminated by standard 

levels are assumed to purchase the design option corresponding to the minimum compliance with 

the standard level. 

4.3.2 Results for LCC Difference 

Supplemental Table 4.39 summarizes the LCC differences for each of the cooking products 

analyzed here. Supplemental Tables 4.42 through 4.71 show the "detailed" parts necessary for 

calculating the LCC differences for each cooking product's first three standard levels. Of these 

"detailed" tables, one set corresponds to a single product class evaluated at a single fuel price 

projection (ither 1995 AEO, 1997 AEO, or 1997 GRI) and, where applicable, a single installation 

cost (either $0, $90 or $18). Three sets of tables are presented for electric non-self cleaning ovens 

(Supplemental Tables 4.42 through 4.44). Nine sets of tables are presented each for gas cooktops 

(Supplemental Tables 4.45 through 4.53), gas non-self cleaning ovens (Supplemental Tables 4.54 

through 4.62), and gas ranges (Supplemental Tables 4.63 through 4.7 1). The results presented in part 

"c" are the weighted average of LCC differences comparing that portion of the projected distribution 

of designs in the base case that are less efficient than the standard level to the design at the standard 

level. Designs with energy consumption at or below the standard level are not affected by the 

standard level, so these are excluded from the calculation of impacts. These LCCs are calculated 

at a 6% discount rate; a higher discount rate (e.g., 15%) gives a smaller difference.

Supplemental Table 4.39 Summary of LCC Differences (@ 6% discount rate) 

Supplemental Table 4.40 summarizes the payback periods (PBPs) of the cooking products 

analyzed here. Supplemental Tables 4.42 through 4.71 show the "detailed" parts necessary for 

calculating the PBPs for each cooking product's first three standard levels. The PBPs by standard 

level shown in Supplemental Tables 4.42 through 4.71 are the weighted averages. They compare that 

portion of the projected distribution of designs in the base case which are less efficient than the 

standard level to the design at the standard level. Designs with energy consumption at or below the 

standard level are not affected by the standard level, and so are excluded from the calculation of 

impacts.

7.1 INTRODUCTION 

The environmental impacts of standard level 3A (elimination of standard pilot lights from gas 

residential cooking products) are presented in this chapter. For a detailed description of the 

methodology that was used in estimating the environmental impacts, please refer to the 

Environmental Assessment in an earlier analysis of residential cooking products1. 

7.2 RESULTS , 

Supplemental Tables 7.1 and 7.2 indicate the degree to which CO,, SO,, andNO, emissions 

will be changed by imposing standard level 3A on cooking appliances. The tables include the 

following information for several different years between 2000 and 2030: the amount of emission 

abated fiom both power plant and £?om in-house generation, the net change in the emissions, and the 

percent the net change comprises of total U.S. power plant emissions. Also included are the 

cumulative changes of each pollutant between the years 2000 and 2030.
