## PROJECTED NATIONAL IMPACTS OF STANDARDLEnLS: 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 quantitiesbetween abase case and each energy efficiency level. These outputs arecalculated 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 forthe end use(s) comprisingthe 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 scenariosare (1)fuel price and housing forecastsbased 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.

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 ofstandard levels to the end ofthe period. Net present value ofthe standard levels is evaluated for each regulated product and for the end use(s) comprising the regulated and competing products.

### In order to project the effect on energy savings ifpilot lights were not allowed on gas ranges and ovens,it is necessary to determinehow 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. Surfacecooktops are those sold separatelywithout an oven. Built-ins refer to ovens that arebuilt into cabinetry and refer only to ovens.

### 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 projectionsof 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

The following tables present the life-cycle costs (LCC) and paybackperiods (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, and4) gas non-self cleaningranges (i.e., acooking appliance consisting of a cooktop and a non-self cleaning oven). The earlierDraft Report 

### on residential cookingproducts demonstrated that the firstthree standard levels forthe 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 followingdesign options:reduced vent rate, improved insulation, and improved seals. For gas cooking products, standard levels one andtwo representthe baseline model while standardlevel three represents the baseline model with either an electricor electronic ignition device.

### 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 appliancesconsidered here, only a singledesign option, an electric or electronic ignition device, is assumed to incur an increase in installation cost. 

### In the case of electricnon-self cleaning ovens, it is assumed that none ofthe design options considered cause an increase in the installation cost. A more complete discussionof the impact on installation cost due to electric and electronic ignition devices for gas cookingproducts will follow. Operating expenses(OE)includeenergyexpendituresand maintenancecosts. Annual energy consumptionis the average unit energy consumptionin thefield (from

### LBNL-EM). Annual energy expense to the consumer is annual energy consumption times energy price. Annual energy consumptionvalues are discussed in detailin Appendix A ofthe earlierDraft Report on residential cooking products. Energy price is the projected average residentialenergy price for the year 2001

### 4.1.1 Installation Costs-Electric and Electronic Ignition Devices
For the gas cooking appliances considered here, all baseline models are assumed to utilize standingpilot ignition devices. Electronic and/orelectric ignition devices are a means in which to eliminate the need for standing pilots and reduce overall energy consumption.

### 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 ofelectric non-selfcleaning ovens, it is assumed that none ofthe design options considered cause an increase in the installation cost. A more complete discussion ofthe impact on installation cost due to electric and electronic ignition devices for gas cooking products will follow. Operatingexpenses (OE) include energyexpenditures and maintenance costs. Annual energy consumption is the average unit energy consumption in 

### thefield (fromLBNL-REM). Annual energy expense to the consumer is annual energy consumption times energy price. Annual energy consumption values are discussed in detail in Appendix A ofthe earlier

### DraftReport 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 1.11 for gas, both derived from DOElEIA's 

### 1990 Residential Energy Consumption Survey. Annual operating expenses are discounted to the year ofpurchase (2001) and summed over the average life ofthe product to obtain a present value. Forthe residential sector, the discount rate is 6% real, with sensitivity analyses perfonned 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 ofa new gas cooking product with an electric and/or electronic ignition device would require the installation ofan electrical wall outlet.

### 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 1993did not have a working electrical outlet in every room. Using RECS housing statistics, this means that approximately 1.9millionU.S. households, according to theAmerican Housing Survey,did not have aworkingelectricaloutletin every room. It is likelythat based on the RECS andAmerican 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 householdsthat might require an electrical wall outlet to accommodate the use of a gas cooking product with electric or electronic ignition, three

### 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

### 4.1.4.1 LCC Results for Gas Cooktops Supplemental Tables 4.7 through 4.15 show the LCes by design option for gas cooktops. Nine tables are presented showing how Lee is impacted by the three different installation cost scenarios and the three different fuel price projections. Under all three different fuel price projections, electronic ignition (standard level three) is shown to have the least Lee (regardless of discount rate) for households not requiring an electrical outlet (installation cost of$0). Under the $90 installation cost scenario, the baseline model (standard levels one and two) has the least Lee regardless ofthe fuel price projection. For the $18 installation cost scenario, electronic ignition has the least Lee for all discount rates under the 1995AEO 

### fuel price projection and for discount rates of2% and 6% under the 1997 GRI

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. Forexample,in thecaseofthe gas range baseline model, annual energy use, installed consumercost, and annual operating expense are constructedby adding the respective values from the baseline models for gas cooktops and gas non-self cleaning ovens. For each of the nine possible combinationsof fuel price and installation cost, the gas cooktopand gas non-selfcleaningoven data sets arepresented along with the constructed data forthe gas range.


### In constructing the data forthe 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 caseswhere the cost of an electricalwall outlet is considered, installation cost savings are realized for both ofthe 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 casewhere electronic ignition is utilizedby 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 componentsare analyzed separately. k



### Supplemental Tables 4.25 through 4.33 demonstrate how LCCs are impactedby 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 lowestLCCs. Thisis due to the factorycost and resulting retail price savings realizedby requiring only one set of ignition controls. At a discountrate of

### LCC SENSITIVITY ANALYSIS
ThenationalLCC results in Supplemental Section4.1 were tested for sensitivityby varying assumptions about energy prices for each product class. The results of this analysis should be compared to the LCC tables in SupplementalSection 4.1.

### STANDARDLEVEL IMPACTSONLIFIE-CYCLE COSTDImRENCES,PAYBACK PERIODS, AND COST OF CONSERVED ENERGY
Standard levels correspond to a set of design options. For the four classes of residential cookingproducts 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 demonstratinghow aparticular standard level affectsLCC, 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 determinedby 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 decreasein 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 efficiencylevel causes a net increase in expenses to the consumer. 1995 1997 1997 Prices Prices $1129 $1076 $1099 $948 $1810 Supplemental Table 4.36 Summary ofLCC Sensitivities for Gas Cooktops Installation Cost

### 4.3 STANDARD LEVELIMPACTS ONLIFE-CYCLE COSTDIFFERENCES,PAYBACK PERIODS, AND COST OF CONSERVED ENERGY
Standard levels correspond to a set of design options. For the four classes ofresidential 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 ofstandard 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 ofdecreased 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.

### The payback period (PBP) measures the amount of time needed to recover the additional consumerinvestmentin increased efficiency through lower operating costs. PBPis foundby solving the equation:

PBP 

### APC +

### 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:

### -- 

### AOC
Numerically, the PBP is the ratio of the increasein purchase (and installation)price from the base to the efficiency levels cases to the decrease in annual operating expenditures (including maintenance). PBPs areexpressedin years. A PBPofthreeyears means that the increasedpurchase 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 lifeofthe productmean that the increasedpurchase 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 dividedby the annual energy savings:

## In Part "c", PBPs arepresented which arebased upon energy use data determined both from the proposed DOE test procedure and recent field measurements. As discussed in the earlierDrafrReport 

### on residential cooking products, recent fielddata indicatethat 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 indicatelowerenergy 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 calculatingLCC differences, PBPs, and CCEs have been discussed previously. 

### In addition, the calculationrequires that a distribution of design optionsisprojected (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 casechoice is eliminatedby standard levels are assumedto purchase the design option correspondingto the minimum compliancewith the standard level.
