### CHAPTER 1. EXECUTIVE SUMMARY

The Energy Policy and Conservation Act (P.L. 94-163), as amended, establishes energy conservation standards for 12 ofthe 13 types ofconsumerproducts specifically covered by the Act. The legislation requires the Department of Energy (DOE) to consider new or amended standards for these and othertypes ofproducts at specified times. DOE is currently considering amending standards for seven types ofproducts: water heaters, direct heating equipment, mobile home furnaces, pool heaters, room air conditioners, kitchen ranges and ovens (including microwave ovens), and fluorescent light ballasts and is considering establishing standards for television sets. This Technical Support Document presents the methodology, data, and results from the analysis ofthe energy and economic impacts of the proposed standards. The economic impact analysis is performed in four major areas:

• An Engineering Analysis, which establishes technical feasibility and product attributes, including energy performance and costs of alternative design options, which improve appliance efficiency. • A ConsumerAnalysis, whichforecasts appliance sales, efficiencies, energy use, and consumer expenditures. • A ManufacturerAnalysis, which provides an estimate ofmanufacturers' responses to the proposed standards. Their responses are quantified by changes in several financial performance measures for a prototypical firm.

• AnImpactAnalysis, whichprovides an integratedframeworkfor assessing the costs and benefits ofappliance standards. The ImpactAnalysis includes: (1) aLife-Cycle CostAnalysis thatevaluates the savings in operating expense relative to an increase in purchase price for individual consumers; (2) a Utility Analysis that measures the impacts of the altered energy-consumption patterns on electric utilities; (3) an Industry ImpactAnalysis that shows the financial and competitive impacts on the respective appliance manufacturing industry; and (4) a Cost-BenefitAnalysis that collects the results ofall the analyses into the net benefits and costs from a national perspective. TheEngineeringAnalysis segregates producttypes into separate classes to whichdifferent energy conservation standards apply. For each appliance class, baseline units are chosen representing relatively low-efficiency units currently being manufactured. The analysis identifies a series ofdesign options to improve energy efficiency andestimates the factory costs to produce them. Design options are added individually or in combination to the baseline unit to evaluate units that might be produced in response to standards. Factory costs are then marked up to 1-1

This Technical Support Document presents the methodology, data, and results from the analysis ofthe energy and economic impacts of the proposed standards. The economic impact analysis is performed in four major areas:

Their responses are quantified by changes in several financial performance measures for a prototypical firm.
• AnImpactAnalysis, whichprovides anintegratedframeworkfor assessing the costs andbenefits ofappliance standards. TheImpactAnalysis includes: (1) aLife-Cycle CostAnalysisthatevaluates the savings in operating expenserelative to an increase in purchase price for individual consumers; (2) a UtilityAnalysis that measures the impacts of the altered energy-consumption patterns on electric utilities; (3) an Industry ImpactAnalysis that shows the financial and competitive impacts on the respective appliance manufacturing industry; and (4) a Cost-BenefitAnalysis that collects the results ofall the analyses into the net benefits andcosts from a national perspective. TheEngineeringAnalysis segregatesproducttypes into separateclassesto whichdifferent energy conservation standards apply. For each appliance class, baseline units are chosen representingrelativelylow-efficiencyunits currentlybeing manufactured. The analysis identifies a series ofdesign options to improveenergyefficiency andestimates thefactory costs to produce them. Design options are added individually orin combination to the baseline unit to evaluate units that might be produced in response to standards. Factory costs are then marked up to 1-1consumer prices, and life-cycle cost curves are constructed for each class. The paybackperiods associated with each incremental change in efficiency are also calculated. The Consumer Analysis focuses on national energy savings and economic impacts on consumers up to the year 2030; It forecasts efficiencies and sales ofnew appliances by class, as well as appliance usage levels in response to changes in projected energy prices and incomes. These results are used to project energy use and consumer expenditures on fuel and equipment. The net present value of the standards is computed by discounting the differences in the time streams ofthese expenditures in the "with" and "without" new standards cases. The Manufacturer Impact Analysis estimates the overall impact of new or amended standards on manufacturers. The analysis examines long-run impacts on (1) profitability, (2) growth, and (3) competitiveness. To do this, two measures ofimpactare tracked for the industry as a whole and for any segments that may exist: (1) retum-on-equity (ROE) and (2) netincome. ROE provides the primary measure ofprofitability; gross margin, return-on-assets (ROA), and return-on-sales (ROS) are alsoreported. The analysis also shows total assets, shipments, average prices, and revenues. Assets and income are the measures of growth (positive or negative). Two short-run impacts are also analyzed. First, the ability ofthe industry as a whole and ofspecific segments ofthe industry to make the one-time investments required to meet the new standards is examined. Second, if standards result in decreased sales for the particular industry being analyzed, the analysis examines the possibility of price-cutting while the industry is adjusting to a lower sales volume. The impacts on individual consumers are evaluated by determining the changes in life-cycle cost resulting from the imposition ofthe proposed standards. The Utility Analysis focuses on revenue changes, avoided costs, and reductions in peak electric loads. Utility-avoided costs represent the marginal value oflower fuel consumption as well as the marginal value oflower investment in new generating plants. Reduction in peak loads can lead to deferring the construction ofnew generating capacity. Because fuel costs and the need for additional capacity are region-specific, the Utility Analysis is conducted on a regional basis.

1-2 consumerprices, and life-cycle cost curves are constructedfor each class. The paybackperiods associated with each incremental change in efficiency are also calculated. The Consumer Analysis focuses on national energy savings and economic impacts on consumers up to the year 2030; It forecasts efficiencies and sales ofnew appliances by class, as well as appliance usagelevels inresponse to changes inprojectedenergyprices andincomes. These results are used to project energy use andconsumerexpenditures on fuel andequipment. The net present value of the standards is computed by discounting the differences in the time streams ofthese expenditures in the "with" and "without" new standards cases. The Manufacturer Impact Analysis estimates the overall impact of new or amended standards on manufacturers. The analysis examines long-run impacts on (1) profitability, (2) growth, and (3) competitiveness. Todothis, two measures ofimpactare trackedfor the industry as a whole andfor any segments that may exist: (1) retum-on-equity (ROE) and (2) netincome.

### CHAPTER 3. ANALYTIC APPROACH

3.1INTRODUCTION 

### The economic impacts ofnew or amended energy efficiency standards depend largely on the relationship between the cost of a consumer product and its energy efficiency. The costefficiency relationships are determined for each product class based on engineering analyses. DOE has segregated product types into classes to which different energy efficiency standards might apply. The product types and the number of classes of each product type are shown in Table 3.1. Within each class, the energy-conserving designs are ordered by cost-effectiveness; then combinations ofenergy-saving design options are used to generate the relationships that are inputs to the other analyses ofthe impacts ofsetting standards at various efficiency levels. Identification of product classes, baseline units, design options, and maximum technologicallyfeasible efficiencies is basedoninformation gatheredfrom the trade associations, manufacturers, discussions with researchers, a literature survey, and comments on the Advance Notice ofProposed Rulemaking (ANOPR). Energy use data have been obtained from AHAM (Association of Home Appliance Manufacturers), GAMA (Gas Appliance Manufacturers Association), FfC (Federal Trade Commission), manufacturers, and simulation models. Sources of factory cost data include manufacturers, suppliers, and the ANOPR comments. The cost estimates arecombined with theefficiencyestimates to generate the cost-efficiencyrelationships. The relationships between manufacturer costs and efficiency that are presented in this chapter are usedthroughout the otherparts ofthe analysis. The engineering analysis also includes determination of maintenance and installation costs for each ofthe design options studied (see
. Appendix F ofthis volume and Chapter 1 ofVolumes B through I). The manufacturer analysis uses manufacturercosts to produceretailprices. Retailprices, installation costs, andmaintenance costs in conjunction with the corresponding efficiencies are used in the forecasting models to forecast sales and efficiencies and to calculate life-cycle costs and payback periods.

### This chapter briefly describes how the economic analysis of standards was performed. Section 3.2 presents an overview of the analytic methodology and discusses the major components of the analysis: the Engineering Analysis, the Consumer Analysis (national and individual), the Manufacturer and Industrial Analyses, and the Utility Analysis. The emphasis is on how these components fulfill the seven legislative requirements listed in the Introduction. This section discusses the interrelationships among the components that ensure consistency throughout the analysis. Section 3.3 describes the computerized models used in the analysis. The models predict consumer, manufacturer, and utility responses to future changes in the economy, including the imposition ofminimum efficiency standards. Quantitative estimates ofthe impacts ofstandards are calculated from the outputs ofthe models. The models utilized in the analysis are:

• Engineering Cost and Performance Models;

• Consumer Impact Models;

• Manufacturer Impact Models;

• Utility Impact Model. The function, data sources, assumptions, and validity ofthe results for each model are discussed in the product-specific volumes (Volumes B through I). Section 3.4 discusses the sensitivity analysis performed on the economic impacts and focuses on the methods used to determine the parameters that have the largest effects and to determine their range ofvariation. 3.2 OVERVIEW OF ANALYTIC FRAMEWORK 

### The impact of appliance efficiency standards is determined by comparing projections of a wide range ofeconomic variables under the existing legislation with the projections under the proposed standards. Foreachofthe eightproducts analyzed, these projections are fIrst made for. a base case (existing legislation) using the analytic models described below. In 

### each productspecific volume, Chapter 2 describes the data and assumptions used to calculate the baseline forecasts. The calculations are then repeated imposing the proposed standards as discussed in Chapter 3. The differences between the projections ofthe energy consumption and economic variables in the base and standards cases provide quantitative estimates of the impacts of the standards. To evaluate the significance ofthe differences, a sensitivity analysis is performedon the key parameters and assumptions.

The emphasis is on how these components fulfill the seven legislative requirements listed in the Introduction. This section discusses the interrelationships among the components that ensure consistency throughout the analysis. Section 3.3 describes the computerizedmodels used in the analysis. The models predict consumer, manufacturer, and utility responses to future changes in the economy, including the imposition ofminimum efficiency standards. Quantitative estimates ofthe impacts ofstandards are calculated from the outputs ofthe models. The models utilized in the analysis are:
• Engineering Cost and Performance Models;
• Consumer Impact Models;
• Manufacturer Impact Models;
• Utility Impact Model. The function, data sources, assumptions, and validity ofthe results for each model are discussed in the product-specific volumes (Volumes B through I). Section 3.4 discusses the sensitivity analysis performed on the economic impacts and focuses on the methods used to determine the parameters that have the largest effects and to determine their range ofvariation. 

### 3.2 OVERVIEW OF ANALYTIC FRAMEWORK The impact of appliance efficiency standards is determined by comparing projections of a wide range ofeconomic variables under the existing legislation with the projections under the proposed standards. Foreachofthe eightproducts analyzed, these projections are fIrst made for
. a base case (existing legislation) using the analytic models described below. In 

### each productspecific volume, Chapter 2 describes the data and assumptions used to calculate the baseline forecasts. The calculations are then repeated imposing the proposed standards as discussed in Chapter 3. The differences between the projections ofthe energy consumption and economic variables in the base and standards cases provide quantitative estimates of the impacts of the standards. To evaluate the significance ofthe differences, a sensitivity analysis isperformedon the key parameters and assumptions.

### The economic impact analysis is performed in seven major areas:

• An Engineering Analysis, 

### which establishes technical feasibility and product attributes including costs ofdesign options to improve appliance efficiency; • A ConsumerAnalysis 

### at two levels: national aggregate impacts, and impacts on individuals. The national aggregate impacts 

### include LBL Residential Energy Model (LBL-REM) forecasts of appliance sales, efficiencies, energy use, and consumerexpenditures. The individual impacts 

### are analyzed by Life-Cycle Cost (LCC), Payback Periods, and Cost ofConserved Energy (CCE), which evaluate the savings in operating expenses relative to increases in purchase price; • AManufacturerAnalysis, 

### which provides an estimate ofmanufacturers' response to the proposed standards. Their response is quantified by changes in several measures offinancial performance for a firm;

• An Industry ImpactAnalysis, 

### which shows financial and competitive impacts on the appliance industry; • A Utility Analysis 

### that measures the impacts of the altered energy-consumption patterns on electric utilities;

• An Environmental Effects Analysis, 

### which estimates changes in emissions of carbon dioxide, sulfur oxides, and nitrogen oxides, because of reduced energy consumption in the home and at the power plant; and • A Regulatory ImpactAnalysis, 

### which collects the results ofall the analyses into the net benefits and costs from a national perspective. A simplified diagram of the analysis is shown in Figure 3.1. Each type of analysis is performed for the eight types of products. If 

### appliances having the maximum efficiency improvement that is technologically feasible show no significant energy savings in the Engineering Analysis, then the legislation requires that no modified standard be prescribed for that product type. .If the appliance efficiency can be increased to produce significant energy savings, then a detailed energy savings, economic, and impact analysis is done. For each ofthe eight products, the analysis is performed for a base case plus several trial levels of standards. The selection oftrial standard levels by class is described in Chapter 3 for each product-specific volume.

•Emissions (C02, NOx, S02)Figure 3.1 illustrates the interaction among the Engineering, Consumer, and Manufacturer Analyses. The Engineering Analysis establishes appliance designs andrelated attributes such as efficiency and costs. Based on these costs, the Manufacturer Analysis predicts retail prices for use in the consumer analysis (the Life-Cycle Cost Analysis and Forecasts). Based on the relationship betweentheprices andefficiencies ofdesign options, the consumer analysis forecasts sales and efficiencies ofnew and replacement appliances. These data are used as inputs to the Manufacturer Analysis to determine fmancial impacts on typical firms within the industry. The consumer analysis also forecasts energy savings andconsumerexpenditures for the purchase and operation ofthe appliances. Consumerexpenditures are used in the Life-Cycle Cost Analysis to determine consumer impacts. Changes in sales, revenues, investments, and marginal costs of utilities are calculated from the energy savings in the Utility Analysis. Three time frames are consideredby the analysis. First, the analysis ofconsumerandutility impacts extends over a time frame consistent with the life ofthe products and includes the time required to approach market saturation. This time frame extends to 2030 and the standards corne into effect in 1996. Second, the Manufacturer Analysis is performed for a typical year after the imposition of standards. Third, the Engineering Analysis examines the technical feasibility of improving the efficiency of appliances before the standards corne into effect-within the next three years. 3.3 MODELS, DATA, AND ASSUMPTIONS 3.3.1 Engineering Cost and Performance Models The Engineering Analysis provides information on efficiencies, manufacturing costs, and other appliance characteristics for use in other components ofthe analysis. Appliance features that provide utility to the consumer are incorporated into the analysis through the creation of appliance classes. Classes are a subset of appliance types. For example, a water heater is an appliance type, but a gas-fired storage water heater is an appliance class. The Engineering Analysis develops cost andefficiency datafor a setofdesign options withineach appliance class. These data are the output ofthe engineering performance and cost models discussed laterin this section. The Engineering Analysis is performed in seven steps: (1) select appliance classes; (2) select baseline units; (3) select design options within each class; (4) determine maximum technically feasible designs; (5) calculate the efficiency improvement provided by each design option; (6) develop cost estimates; (7) generate cost-efficiency relationships. Appliance Classes The first step in the Engineering Analysis is the segregation ofproduct types into separate classes to which different energy-efficiency standards apply. DOE differentiates classes by the type ofenergy used (oil, natural gas, orelectricity), and capacity orperformance-relatedfeatures that provide utility to the consumer and affect efficiency. For specific appliances, classes are defmedusingdatacollectedin discussions with appliancemanufacturers, trade associations, other interestedparties, and from comments received on the Advance Notice ofProposedRulemaking. 3-5 Figure 3.1 illustrates the interaction among the Engineering, Consumer, andManufacturer Analyses.

Appliance features that provide utility to the consumer are incorporated into the analysis through the creation of appliance classes. Classes are a subset of appliance types. For example, a water heater is an appliance type, but a gas-fired storage water heater is an appliance class.

For specific appliances, classes are defmedusingdatacollectedin discussions withappliancemanufacturers, trade associations,other interestedparties, andfrom commentsreceivedon the Advance NoticeofProposedRulemaking. 3-5Those classes for which no DOE test procedure has been specified are omitted. The appliance classes covered by the analysis are listed in Chapter 1 ofeach product-specific volume. 

### Baseline Units A baseline unit is the starting point for analyzing design options for improving energy efficiency. To select a baseline unit, the Engineering Analysis uses information gathered from trade organizations, manufacturers, consultants with expertise in specific producttypes, andfrom public comments on the Notice ofProposed Rulemaking. For each product class, the baseline unit generally represents a model with the maximum allowable energy use specified by the National Appliance Energy Conservation Act (NAECA). Other than efficiency, features are representative ofthe class as a whole. 

### Design Options The Engineering Analysis identifies individual or combinations of design options with a potential for improving energy efficiency. Design options that are commercially available at the present time or that are presentin prototypes are considered. They are selected afterdiscussions with experts and an extensive literature review. The efficiency improvement and manufacturer cost ofdesign options added to the baseline unit are calculated. 

### Maximum Technologically Feasible Designs For each product class, a maximum technologically feasible design option or combination of design options is identified. This option, or combination of options, results in the highest energy efficiency for each productclass. The maximum technologically feasible efficiency level is one that can be reached by the addition ofdesign options, both commercially feasible and in prototypes, to the baseline units. This design must be possible to assemble, but not necessarily to manufacture in large numbers. Economic criteria are applied to all design options in other parts ofthe analysis. 

### Efficiency Calculation For each of the product classes, the efficiency levels corresponding to various design options are determined from manufacturer data and from engineering calculations. 

### Cost Estimates The manufacturer cost data are obtained through a lengthy process that included meetings and tours atmanufacturing facilities, submission offonnal requests to manufacturers for costing data, and review of the data received. Estimates of manufacturer cost are also received in response to the Notice ofProposed Rulemaking. In each product-specific volume, Appendix A contains detailed incremental cost data disaggregated into labor, purchased parts, materials, shipping/packaging and tooling. 3-6 Those classes for which no DOE test procedure has been specified are omitted. The appliance classes covered by the analysis are listed in Chapter 1 ofeach product-specific volume.

### Cost-Efficiency Relationships The results ofthe Engineering Analysis are summarizedin the cost-efficiency relationships showing the efficiency and manufacturer cost of the design options for each appliance class. Manufacturer and dealer markups derived in the Manufacturing Analysis are applied to the factory costs to 

### arrive at the purchase price of the appliance. Additional installation costs required for some designs are included in the purchase price. Additional maintenance costs associatedwith specific design options are also estimated. The price-efficiency relationships are a fundamental input to the Consumer Analysis. 

### Assumptions in the Analysis Justifications for the most important assumptions of the Engineering Analysis are listed below.

•

•

• Assumption 

### Industry production processes can be characterized in terms of medium and large manufacturing facilities.

Baseline units can be selected to represent typical product offerings within a class.

Unit energy consumption is based on DOE usage estimates, unless otherwise noted. Justification 

### Manufacturing costs for small manufacturers are highly varied because of dependence on purchased parts and sensitivity to labor and distribution costs. An effort was made to obtain these data, but they were not made available by small finns. Because of this difficulty and the fact that they represent a small fraction of total shipments for most of the product classes, analysis concentrated on the medium and large manufacturers. The baseline unit is the starting point to which design options are added to create higher efficiency units. The selection of baseline units is based on studies ofproducts on the market in 1990 and consultations with manufacturers. As part of the Consumer Product Efficiency Standards program, DOE was required to establish testprocedures to determine average consumer utilization and energy usage for the covered products. Test procedures for each product type have been promulgated and were employed to determine unit energy consumption throughout the Engineering Analysis;

### Data Sources Shipment data are based on information from industry sources and published data from industry trade associations. Costs ofpurchased materials andparts are basedon quotations from product manufacturers and suppliers of these items. Data on engineering and labor costs are taken from on-site visits to manufacturing plants and from manufacturer information. Data characterizing baseline units for each class are based on infonnation from industry sources and

.published data. 

### Outputsfrom the EngineeringAnalysis For each combination of design options considered in the analysis, the models and data provide:

• energy efficiency (expressed as the DOE energy factor3 and/or unit energy consumption);

• increased material, labor, and investment costs by product class for medium and large manufacturers;

• annual energy consumption per unit (based on DOE test procedures);

• the relationship between cost and energy use by product class; and

• other information on product characteristics such as appliance lifetimes, installation costs, and maintenance costs. 

### Validation ofthe Results Experimentaldataon efficiencies are available for some ofthe design options studied. For the others, engineering calculations based on physical principles are performed. 3.3.2 EPRI COMMEND COMMEND is a commercial end-use forecasting program supported by EPRI (Electric .PowerResearch Institute). COMMEND forecasts energy use by enduse and building type. The model covers eleven building types, ten end uses, and three fuel types. Version 3.2 was usedfor this analysis (1).

### Forecast fuel- prices and floor space are exogenous inputs to COMMEND. COMMEND models fuel switching and selection ofequipment basedon life-cycle-costcriteria. There are four groups ofdecision-makers, each with a different discount rate. Short-run price elasticities for utilization ofenergy services are included. Interactions between lighting and space-conditioning energy use are also handled within the model. 

### Representation ofTechnologies In COMMEND, technology options are represented as a technology trade-offcurve that shows the efficiency attainable for a given equipment cost. Technology trade-offcurves are defined for at least one equipment market for each energy end use. COMMEND defines only one curve for the lighting end use. For heating, however, separate trade-offcurves are defined to model equipment markets for technologies using different fuel types. A trade-offcurve for a particular building type is defined by the year, equipment cost level, average Energy Use Intensity (EUI kWh/sq ft-year), and an elasticity representing the cost-efficiency relationship. Several equipment components make up the lighting end use: lamps, ballasts, fixtures, and controls. With COMMEND's present structure, it is not possible to represent the actual technology options for lighting directly; instead, technology options have to be mapped onto the technology trade-off curves for the single lighting end use by analyses performed outside COMMEND. Lighting component spreadsheets are used to derive lighting power densities (watts/sq ft) for each building type based on the energy characteristics and penetrations ofthe different component technologies; these densities are then converted to EUIs using building operating hours developed from EIA data (2). 

### Development ofCOMMEND Input The basic relation modeled by COMMEND is that lighting energy use is the product of floor area (in square feet for a given end use) and energy use per unit area (in 

### kilowatt-hours per square foot) for that end use, or EUI, summed over all building types. The analysis integrated a variety of data: current market shares, recent usage trends for various lighting products, and the LBL engineering analysis wattages and costs. The results of this integration were used first to develop a base case set oflighting EUIs. These EUIs were then used to calibrate COMMEND anddevelop reference forecasts againstwhich the netimpacts of the policies were estimated. The base case lighting EUIs were then modified to reflect the impact oflighting equipment and building standards. The difference in forecasts between the base case and the policy is the net energy impact.

### Turnover of Lighting Equipment At present, only one lifetime may be specified for the lighting end use in the model even though lamps usually have to be replaced much more frequently than ballasts and fixtures. Discrete lighting component representation is expected to be a feature of COMMEND Version 4.0. A lifetime of 15 years is used in this analysis. Fifteen years approximates the average lifetime ofballasts,4 and corresponds to the average fixture turnover rate in renovated buildings. 

### Annual Operating Hours To represent hours per year that commercial sector lighting equipment is operating for each building type, building operating hours from NBECS 1986 are used. (2) 

### Calibration As a first step in the calibration process, comparisons between COMMEND inputs and NBECS 1986, EIA's Annual Energy Outlook 1991 (AEO) (3), and State Energy Data Report Consumption, 1960-1989 (SEDR) (4) data were made in order to verify default assumptions in the model. Although there aredefinition discrepancies in the building types usedby COMMEND and NBECS, as well as a 10% disagreement over the commercial building stock total, EUIs for most building types and total consumption across segments correlate well. The calibration for the lighting end use incorporated available data on the state of the market in 1986 and the predicted state in 1995. Trends in the characteristics of the lighting' end-use trade-off curves were defined to capture ongoing incentive programs, existing energy regulations, and marketequipmentcostreductions thattake the marketfrom the 1986 state to the predicted 1995 state. To achieve this transformation, existing programs and regulations were'

--- assumed to reduce the cost of high-efficiency technology options by 30% initially, and by an additional 1% per year, for a total of42% from 1983 to 1995. These assumptions are close to what is happening in the market in the form of cost reductions from utility rebate programs, which typically offer 3-4 cents/kWh saved to their participants. 

### Baseline Forecasts As described in Volume B, Chapter 2, three different baselines, No Programs, Base Case, andHigh-Efficiency are used to gauge the impacts ofpolicy actions. In all three baselines, tradeoffcurves for all end uses other than lighting remain stationary. Forthe No Programs baseline, the technology trade-off curve for the lighting end use is also held stationary at its 1983 level throughout the forecast period.

### 3-10For the High-Efficiency baseline, the 42% costreduction (because ofDSM programs. etc.) in the efficient end ofthe lighting technology trade-offcurve is left in place after 1995. and the trade-offcurve remains in its 1995 state. Forthe Base Case baseline. most ofthe price reduction at the efficient end ofthe trade-offcurve (30 ofthe 42%) is removed after 1995 to model a case in which utilities no longer provide DSM incentives. The remaining cost reductions are left in place in orderto simulate the permanentprice effect thatDSM programs andothermarketforces will have on the market for efficient technologies. In addition. the Base Case baseline includes small savings from state building codes that are introduced before 1995 and are expected to persist (see "Representation ofPolicies" below for a discussion of standards implementation in the model). Thesethree baselineforecasts provide aframeworkfor analyzing abroad spectrum offuture market scenarios. When the No Programs forecast is compared to the other two baselines. the effect of utility demand-side programs plus existing regulations and market forces can be estimated. The two othercases represent two bounds ofthe forecast range. The High-Efficiency baseline extends the 1995 market forecast to 2030. based on utility DSM programs. the EnvironmentalProtectionAgency (EPA) GreenLights Program. theFederalEnergy Management Program (FEMP) relighting program and existing lighting regulations. This case represents an aggressive level ofincentives. butnot a "maximum efficiency" scenario. TheBase Case baseline accounts for the currently widespread DSM activity. but assumes that these programs do not persist at their current high level. COMMEND uses an average consumer discount rate of 28% to model commercial consumer decision-making. Representation of Policies Component efficiency standards are modeled by limiting the choice ofdecisionmakers at the low-efficiency end ofthe lighting technology trade-offcurve. 

### 3.3.3 LBL Residential Energy Model (LBL·REM) Purpose TheLBL-REM models the appliancepurchase choices made in households, as well as these households' subsequent usage behavior and energy consumption. See Appendix B for details about the model. Engineering. economic. anddemographic dataare usedinLBL-REM. The engineeringdata for appliances are describedin Section 3.3.1. Additional data include engineering dataregarding alternative building shellconstructionmeasures andcosts. unitenergyconsumption andefficiency ofappliances. age distribution ofexisting appliance stock. and retirement functions. Economic data include projected energy prices and household income and models ofenergy investment. appliance purchase. and usage behavior (including fuel and technology choice for each enduse). 3-11 Forthe High-Efficiency baseline, the 42% costreduction (because ofDSMprograms, etc.) in the efficient end ofthe lighting technology trade-offcurve is leftin place after 1995, and the trade-offcurveremains in its 1995 state. Forthe Base Case baseline, most ofthe pricereduction at the efficient end ofthe trade-offcurve (30 ofthe 42%) is removed after 1995 to model a case in which utilities no longer provide DSM incentives
. The remaining costreductions are left in placein orderto simulatethe permanentprice effectthatDSMprograms andothermarketforces will have on the market for efficient technologies. In addition, theBase Case baseline includes small savings from state building codes that are introduced before 1995 and are expected to persist (see "Representation ofPolicies" below for a discussion of standards implementation in the model). Thesethreebaselineforecasts provideaframeworkfor analyzing abroadspectrumoffuture market scenarios. When the No Programs forecast is compared to the other two baselines, the effect of utility demand-side programs plus existing regulations and market forces can be estimated. The two othercases representtwo bounds ofthe forecast range. TheHigh-Efficiency baseline extends the 1995 market forecast to 2030, based on utility DSM programs, the EnvironmentalProtectionAgency (EPA) GreenLightsProgram,theFederalEnergyManagement Program (FEMP) relighting program and existing lighting regulations. This case represents an aggressive levelofincentives, butnot a "maximumefficiency" scenario. TheBase Casebaseline accounts for the currently widespread DSM activity, but assumes that these programs do not persist at their current high level. COMMEND uses an average consumer discount rate of 28% to model commercial consumer decision-making. Representation of Policies Component efficiency standards are modeled by limiting the choice ofdecisionmakers at the low-efficiencyend ofthe lighting technology trade-offcurve. 

### 3.3.3 LBL Residential Energy Model (LBL-REM) Purpose TheLBL-REM models the appliancepurchase choices made inhouseholds, as well as these households' subsequent usage behavior and energy consumption. See Appendix B for details about the model. Engineering,economic, anddemographic dataare usedinLBL-REM. Theengineeringdata for appliances are describedin Section 3.3.1. Additional dataincludeengineeringdataregarding alternativebuildingshellconstructionmeasures andcosts,unitenergyconsumptionandefficiency ofappliances, age distribution ofexisting appliance stock, and retirement functions. Economic data include projected energy prices and household income and models ofenergy investment, appliancepurchase, andusage behavior (including fuel and technology choice for each enduse). 3-11Demographic data include number of households by type, projected housing starts and demolitions, and appliance holdings. 

### HistoricalDevelopment Early energy-demand modeling focused on engineering estimates or on the relationship between energy consumption and economic growth. In the 1970s, Oak Ridge National Laboratory (ORNL) developedthe fIrst model to integrate these two important aspects ofenergy demand, the Engineering-Economic Model ofResidential Energy Use. (5) The ORNL Model was brought to LBL in 1979 and adapted to the analysis of federal appliance conservation standards. Further extensive changes were made at LBL from 1979 to the present, resulting in the LBL-REM.(6) Many of these changes have already been documented. (7) More recent changes for this rulemaking are described in Appendix B. 

### Structure ofthe Model The LBL-REM segments annual energy consumption into house types, end uses, and fuel types. The house types include single-family, multifamily, and mobile homes. Calculations are performed separately for existing and new housing construction each year during the forecast period, 1980-2030.5 The end uses are space-heating (including room and central), airconditioning, water heating, refrigeration, freezing, cooking, dish-washing, clothes-washing, clothes-drying, televisions, lighting, and miscellaneous. Up to four fuels are considered, as appropriate to each enduse: electricity, natural gas (utility gas), heating oil, andliquidpetroleum gas (LPG). The national version of the model, which treats the country as a single region, is used in the analysis. The model projects five types of activities: technology/fuel choice, building shell thermal integrity choice, appliance efficiency choice, usage behavior, and turnover of buildings and-.-." appliances. The interrelationship ofthe five types of activities is shown in Figure

### Housing StockSubmodel This submodel prepares data about the housing stock projection forthe main model. The initial numberofoccupiedhouseholds, by type, is taken from the 1980 Census ofPopulation and Housing and an exogenous projection of housing starts is obtained. The housing submodel determines the projected housing stock for each year from 1981-2030 by house type, based on the projected age distribution ofthe population in each state. The method is described fully in Appendix B. 

### Efficiency Choice Algorithm Historicalefficiency data are available for selectedyears through 1991 for each ofthe eight products. After 1991, efficiency improvements are projected as a function ofdesigns available (technological change) and of electricity, oil, or gas prices. If 

### energy prices increase, the life-cycle cost of more efficient designs will increase more slowly than that of less efficient designs, making the more efficient designs more attractive. When the life-cycle cost ofa more efficient design falls below the life-cycle cost of the current average design, then the more efficient design is projected to be purchased. Conversely, ifenergy prices decline, the model projects no further efficiency change. 

### Thermal Integrity The projection ofinvestment in thermal integrity measures in new houses is based on a life-cycle cost calculation analogous to that done for equipment efficiencies.6 

### Engineering estimates ofthe incremental costs ofthermal integrity measures are used together with current fuel prices and a market discount rate for each house type and heating fuel type. 

### Modeling Efficiency Standards TheLBL-REMprojects theaverageefficiency ofnewproducts, e.g., gas-firedwaterheaters, purchased each year in the absence of additional federal regulations, as described above. A distribution ofunit energy consumptions (VEC) 

### is constructed around the projected average unit energy consumption for each class, based on efficiency distributions previously observed in the marketplace. New federal standards would eliminate at least part of the distribution. A new distribution is constructed in which all sales below the standards are increased in efficiency to meet the standards. The new shipment-weighted average efficiency then characterizes the efficiency of new units in that year. The same process is applied to all years after implementation ofthe standards. The model is then run again, for the standards case, with the adjusted average efficiencies, to calculate any changes in market shares, usage behavior, or investment in building shell thermal improvements that may occur as a result ofstandards, and to calculate the net energy savings.

6 The equipment efficiency and thermal integrity decisions are not solved simultaneously, but recursively. The previous year's thermal integrity is assumed in projecting this year's equipment efficiency; then this year's equipment efficiency is used to calculate this year's thermal integrity.

### Turnover of Appliance Stocks The initial age distribution ofappliances in stockis characterizedfrom industry data about historical annual shipments and retirements. The fraction ofeach product that retires each year is based on the number of years since purchase for each age cohort.? Each age cohort is associated with an average efficiency; when older appliances retire, they are also typically recognized as less efficient. The number ofpotential purchasers ofan appliance in new homes is equal to the number ofnew homes constructed each year. The number ofpotential purchasers in existing houses is equal to the number ofretiring appliances, plus some fraction ofthose households that did not previously own the product. 

### Calculation of Market Shares Potential buyers may make no purchase or may buy any competing technology within an end use. For each of the eight products, the decision to purchase or not is modeled, and the fraction ofthe total thatchoose each class, e.g., gas-fired, oil-fIred, electric, or gas instantaneous waterheaters, is specified exogenously. Long-term market share elasticities have been assumed withrespectto equipmentprice, operating expense, andincome. Standards are expectedto create lower operating expenses and increased equipment prices. The percentage changes in these quantities are used, together with the elasticities, to determine changes in market share resulting from standards. Higher equipment prices will decrease market shares, while lower operating expense will increase market shares. The net result depends on the standard level selected and associated equipment price and operating expense. 

### Usage Behavior For some products, changing the operating expense results in changes in usage behavior. These changes are modeled with usage elasticities in operating expense and income. For fluorescent light ballasts, televisions, water heaters, and pool heaters, these elasticities are assumed to be zero. Forranges and ovens, room air conditioners, direct heating equipment, and mobile home furnaces, these elasticities are assumed to be non-zero.

7 For example, a cohort consists ofall 8-year-old gas-fired water heaters. Up to 30 cohorts, one for each year ofpurchase, are tracked for each purpose. 3-15

### Energy Consumption Calculations The total energy consumption per house for each end use and fuel by house type and vintage (existing or new) is the product ofthe VECpercycle (accounting for efficiency changes) and usage factor, e.g., cycles peryear. The corresponding energy consumption for all households is the consumption perhouse times the numberofhouseholds ofthat type and vintage, times the fraction ofhouseholds that owns that appliance.8 Aggregate energy consumption is obtained from summations overintennediate results. For example, national electricity consumption for residential water heaters in a particularyear is the sum, over house types, classes, and vintages, of electricity consumption by water heaters. National residential electricity consumption in that year is the sum ofelectricity consumption over all end uses. 

### Assumptions in theAnalysis The Consumer Analysis assumes that decisions on the purchase and use of appliances depend on operating expenses, household income, and appliance prices. Manufacturers are projected to respond to the demand for more efficient products by incorporating technologically feasible and cost-effective design options in new units. Exogenous forecasts of population growth, housing starts, personal income and energy prices from published sources are utilized. Justifications for the most important assumptions in the Consumer Analysis are listed below.

• Population growth is projected to follow Census projections to the year 2000 and population growth is projected to slow from 2000 to 2015.

• The fraction ofthe population in each age group in each state that lives in aparticular house type is projected to remain constant over time.

• Housing starts in future years are projected to range from 900,000 to 1,100,000 singlefamily units; 300,000 to 530,000 multifamily units, and 170,000 to 210,000 mobile homes.

• Real disposable personal income is projected to. grow from $3.9 trillion in 1990 to $7.7 trillion in 2030 (in 1990 dollars). This corresponds to disposable personal income per household growing from $41,500 in 1990 to $59,400 in 2030.

• In real terms, residential electricity prices are projected to increase at an average annual rate of 0.3% from 1989 to 2010, and 0.6% from 2011 to 2030. Residential natural gas prices are projected to increase at an average annual rate of 2.1 % from 1989 to 2010, and 2.2% from 2011 to 2030. Residential distillate prices are projected to increase at an average annual rate of 1.5% from 1989 to 2010, and 1.3% from 2011 to 2030.

3-17 Justification A Census projection ofpopulation by state, by age group, benchmarked to the 1980 Census count, provides the basis for the projection to 2000. The projection given in the 1985 OBERS BEA Regional Projections is consistent with Census projections to 2000 and shows slower growth after 2000. As the age distribution and the geographic distribution of the population change, the mix of house types will also change. A long-term forecast from Data Resources, Inc., represents a state-ofthe-art projection for single-family and multifamily units. The projection for mobile homes is based on the population projection. The DOE/EIAAnnual Energy Outlook 1991 (8) provides the projection to 2010, which is extrapolated to 2030. The extrapolation is linear, based on the 2010 to 2015 trend.

### Data Sources Justification Research on equipment sales for competing alternatives and on historical efficiencychoices indicatesthatoperating expenses are significant variables. Industry is competitive and historically has responded to changes in consumer demand. No evidence suggests an endto the responsiveness. Increasing energy prices and awareness on the part ofconsumers have resulted in modified construction practices and in home retrofits. 'Building codes under consideration, utilitycompany incentives, and projected long-term energy price increases suggest that further thermal improvements are likely. Retirement functions are based on reconciliation of appliance stocks and shipments. Lifetimes may include engineering and economic determinants, which are not separated in existing studies.

TheLBL-REM takes the energy efficiencies ofnew equipmentfrom theEngineering Analysis. Thepurchaseprice ofthese products is derivedfrom the factory cost suppliedby the Engineering Analysis and adjusted for manufacturer and dealer markups in the Manufacturer Analysis. Data on housing and equipment stocks as well as historical data on housing starts and n.ew equipment purchases come from the 1980 census and industry trade associations. Exogenous projections ofpopulation, housing starts, income, and energy prices are taken from Census, Data Resources, Inc., and DOE, respectively.

### Model Outputs The principal outputs from the LBL-REM for each year are:

• Energy consumption by end use and fuel;

• Per-unit equipment price and operating expense by product;

• Total residential energy consumption by fuel;

• Projected annual shipments ofresidential appliances; and

• Differences in these quantities between a base case and each standards case. 'These outputs are provided annually (or for selected years) and cumulatively for the period 1996-2030. Energy savings from implementation ofstandards are provided annually to the end 'ofthe period. Netpresent value (NPV) ofstandards is evaluated for each regulatedproduct and for the end use(s) comprising the regulated and competing products. 

### Cost-BenefitAnalysis The costs and benefits of the proposed standards from a national perspective are quantified by calculating a net present value. The NPV is the sum of discounted savings in operating expenses minus the sum ofdiscounted increases in equipment prices. DOE has determined that 6% real is the appropriate discountrate for calculating benefits to the consumer. The NPV ofstandards is also calculated at consumerdiscountrates of2% and 10% as sensitivity analyses. Different assumptions about technology choice are invoked when calculating energy savings ofstandards on the one hand, and when calculating the net present benefit ofstandards on the other. Energy savings are the net ofany adjustments households make in changing their technology orfuel choice orfrom using appliances differently. For example, if, after standards, a regulated product captures larger market shares (without displacing consumption of another fuel), then the net energy savings will be diminished. The energy savings are calculated as the net result of standards, accounting for such secondary effects as shifts in market share. NPVexcludes these secondaryeffects. Basecasepurchasebehavior, withoutmarketshare changes, is assumed in calculating the NPV, because any market share shift reflects the consumer'sjudgment that change is worth more than the direct energy savings associated with keeping market share constant. NPV is calculated from per unit changes in equipment and operating costs, multiplied by'standards case shipments. If the NPV was calculated without normalizing to shipments, theresults wouldbe erroneous: ifstandards causeddecreasedpurchase ofaproduct, this would appear as an economic benefit, namely less money spent on purchasing 3-19

### LBL Manufacturer Impact Model (LBL.MIM) ConceptualApproach TheManufacturerImpactAnalysis estimates both the short- andlong-runimpacts ofnew or amended standards on profitability (return on equity) and many other variables for each industry under consideration. All computations used in this analysis are carried out by the ManufacturerImpact Model (LBL-MIM), which is a spreadsheetcomposed ofthirteen modules. Figure 3.3 lists these and displays their interactions. In addition to computing estimated values for the above-mentioned descriptive variables, the LBL-MIM also computes standard errors for eachby explicitly evaluating the standarderrors inthe estimates ofinputvariables andthen using Monte Carlo simulations. 

### Measures of Impact Three types of long-run impacts are analyzed: (1) profitability, (2) growth, and (3) competitiveness. To do this, the following five measures ofimpactare tracked for the industry: (1) shipments, (2) price, (3) revenue, (4) net income, and (5) return on equity (ROE). ROE is the primary measure ofprofitability, although gross margin, return on assets, and return on sales are also reported. Changes in assets and revenue are the measures of growth (positive or negative).

### LBL Manufacturer Impact Model (LBL.MIM) ConceptualApproach TheManufacturerImpactAnalysis estimates both the short- andlong-runimpacts ofnew or amended standards on profitability (return on equity) and many other variables for each industry under consideration. All computations used in this analysis are carried out by the ManufacturerImpact Model (LBL-MIM), whichis a spreadsheetcomposedofthirteen modules. Figure 3.3 lists these and displays their interactions. In addition to computing estimated values for the above-mentioned descriptive variables, the LBL-MIM also computes standard errors for eachby explicitlyevaluatingthe standarderrorsinthe estimatesofinputvariables andthenusing Monte Carlo simulations. 

### Measures of Impact Three types of long-run impacts are analyzed: (1) profitability, (2) growth, and (3) competitiveness. To do this, the following five measures ofimpactare trackedforthe industry: (1) shipments, (2) price, (3) revenue, (4) net income, and (5) return on equity (ROE). ROE is the primarymeasure ofprofitability, although gross margin, return on assets, and return on sales are also reported. Changes in assets and revenue are the measures of growth (positive or negative). Because all the industries analyzed are in an historical process of consolidation, any decrease in ROE will tend to hasten this process; thus, ROE also provides an indication ofthe impact ofstandards on competitiveness. A short-run calculation is also made. Ifthe long-run calculation indicates a decrease in sales, thepredictedpriceisreducedbyanamountdeterminedby theindustry'sobservedbehavior during historical downturns in sales. The adjusted price is used to calculate the other measures ofimpact.

Then, no money would be spent onpurchasing the product, or onoperatingexpenses, and the valueofthe savings would equal the amountofmoney thatwould have been spent withoutthe standards. Clearly, this would be a misrepresentation ofthe NPV ofstandards. 3-20Operating Cost Inputs Long-Run Calculations

### Description ofthe LBL-MIM Although LBL-MIM examines many aspects ofan industry, its most importantjob is to compute the effect on profits of a cost increase caused by standards. To accomplish this, the model first estimates how much ofthe cost increase is passed on in the form ofhigher prices. (An accompanying effectis the decrease in operating expense due to standards, which makes the product more desirable to the consumer and, thus, increases demand for the product.) Then, it estimates how this price increase and the accompanying reduction ofoperating expenseinfluence demand. Finally, given the new price and level ofdemand, it computes a new level ofprofit. These calculations use estimatedlong-run costs. TheLBL-MIM makes an additional calculation to correctfor any short-run difficulties the industry may have in achieving its long-run markup. Itis important to note from the start that the model does not assume perfect competition, nor does it assume that the level of profit will remain unchanged. The results of the model depend entirely on the input values. The basic behaviorofthe model can be understoodonly inlightofthe following standard economic consideration. In the long run, an increase in

### not bepassedon via a priceincrease exceptwhenitis sufficientto cause some firms to leave the industry.to This result is derived from the assumption that firms act individually to maximize profits and from the definitionoffixed costs as those that are notproportional to output. The mathematical derivation is given in Appendix C ofthis volume. A second influence on profits is the change in purchases resulting from both the change in price and the change in operating expense. These tend to offset each other because price increases lower quantity demanded, and increased efficiency increases demand (by lowering operating expense). The LBL-MIM takes these effects into account through the use of two demand elasticities which play an important role in determining the outcome and are therefore examined more closely in the sensitivity analysis. 

### Assumptions in the Analysis This section begins with a series ofshort discussions ofdifferent aspects ofthe modeling procedure that require careful interpretation (such as "long-run variable cost") or simplifying assumptions. This is followed by a list ofmore detailed assumptions. 

### The long-run costs. The LBL-MIM requires input 'of long-run costs. A fmn is in long-run equilibrium when it has optimal productive capacity. Thus, during a recession (when fmns experience excess capacity), firms are not in long-run equilibrium, and the theory ofprice as a markup over long-run costs may not apply. Long-run fixed costs are those that remain unchanged when a fum moves from one long-run equilibrium to another; they do not include

### capital costs that are proportional to output. The latter are considered long-run variable (marginal) costs and are marked up and passed on. To the extent that costs are not strictly proportional to output, but decrease on average with quantity produced, there are fIxed costs. Also, a cost that does not depend on the scale of production, i.e., an engineering cost, is a long-run fIxed cost. Use of "typical"firm. 

### The analysis estimates the impact of the standards by using "typical" fInns. A typicalfinn is ahypothetical fInn thatis describedbyindustry-averagevalues. Each one is modeled as if it produced only products of the industry being analyzed. This procedure isjustifIedby the observation thatreal fIrms generally are organized into autonomous divisions, each of which produces a different type of appliance and one of which generally corresponds to the industry being modeled.

### A change in standards affects the model in three distinct ways. In 

### general, stricter standards will require additional investment, will raise production costs, and will affect revenue through both price and demand. The most obvious investment induced by standards is the purchase of new plants and equipment. This cost is fIrst evaluated from engineering data, and then amortized by taking into account the life ofthe investment, the date at which itis made, tax laws, andthe appropriate cost offunds. An additional, and sometimes larger, investment takes place as the old inventory is replaced with more expensive new units. The model assumes that the ratio of inventory to

### Several simplifying assumptions are used in the process ofgenerating inputs for the LBL-MIM. First, all firms within a particular industry segment (e.g., large manufacturers of water heaters) are assumed to have the same cost structure. Second, it is assumed that fmandal data collected for the parent company are representative ofthe specific product division being studied. These data come from p.ublicly available sources such as Value Line, Standard and Poor's, Moody's, and company reports.

### ImpactAnalysis: An Overview The next section provides a general discussion of the methods of the impact analysis together with some cautions about interpreting the results. Most, but not all, ofthe discussion applies to all eight products. The significance oflong-run impacts and how they are analyzed are discussed below. These impacts are most important simply because they will either persist or be so severe as to cause a restructuring of the industry. The meaning and analysis of short-run impacts are also discussed. Additionally, thevarious types ofsensitivity analysis performedon the model's results are discussed. This analysis is crucial for understanding the accuracy and reliability of the model's predictions, andincludes the use ofalternative scenarios, sensitivity checks onindividual inputs, and Monte Carlo simulations involving the random selection ofall control inputs.
3.3.4.1 Long-Run Impact Analysis 

### Implementation The heart ofthe model is the long-run impact analysis. It assumes that enough time has passed for any changes in demand to have been accommodated by changes in the industry's productive capacity. Thus, in the long-run, capacity, orcapital stock, is variable. Because capital is sometimes thought to be the only fixed cost, it might seem that fixed costs would be zero in the long run. This is not the case. For the purpose ofprice determination, whenever there are returns to scale, there are, effectively, fixed costs. This means that if the cost of meeting standards is less than proportional to plant capacity, there are fixed costs. Design costs would typically fall into this category. See Appendix C.2.1 of this volume for a more detailed discussion ofthe long run. The fraction of increased costs of production (due to more stringent standards) that manufacturers are able to pass on is determined by the nature ofthe cost, i.e., whether it is fixed or variable, the price elasticity of demand, and the consumer discount rate as seen by the price-setting firm. Once the price increase has been determined, it and the operating expense decrease (obtained from engineering data) are used with the price elasticity ofdemand and the discount rate to determine the change in sales. These mechanisms are presented in Figure 3.4, which displays the most basic economic forces analyzed by the LBL-MIM. Instead, the reduction in operating costs makes the appliance more desirable, thereby shifting the demand curve out (e.g., an increase in production costs changes the marginal cost curve). Together, these determine price and the number ofunits shipped (quantity). Price and quantity, together with production costs, determine net income (profit), and these, together with changes in capital stock (not shown), determine return-on-equity (ROE). As shown inFigure 3.4, the two costchanges do nottranslate directly intoprice changes. 3-25

It assumes that enoughtime has passed for any changes in demand to have been accommodated by changes in the industry's productive capacity. Thus, in the long-run, capacity, orcapital stock, is. variable. Becausecapital is sometimes thought to be the only fixed cost, itmight seem that fixed costs wouldbe zero in the longrun. This is not the case. Forthe purpose ofprice determination, whenever there are returns to scale, there are, effectively, fixed costs. This means that if the cost of meeting standards is less than proportional to plant capacity, there are fixed costs. Design costs would typically fall into this category. See Appendix C.2.1 of this volume for a more detailed discussion ofthe long run. The fraction of increased costs of production (due to more stringent standards) that manufacturers are able to pass onis determinedby the nature ofthe cost, i.e., whetheritis fixed or variable, the price elasticity of demand, and the consumer discount rate as seen by the price-setting firm. Once the price increase has been determined, it and the operating expense decrease (obtained from engineering data) are used with the price elasticity ofdemand and the discount rate to determine the change in sales. These mechanisms are presented in Figure 3.4, which displays the most basic economic forces analyzed by the LBL-MIM. Instead, the reduction in operating costs makes the appliance more desirable, thereby shifting the demand curve out (e.g., an increase in production costs changes the marginal cost curve). Together, these determine price and the number ofunits shipped (quantity). Price and quantity, togetherwithproduction costs, determine netincome (profit), andthese, together with changes in capital stock (not shown), determine return-on-equity (ROE). As showninFigure3.4,the twocostchanges donottranslate directlyintopricechanges. 3-25The LBL-MIM simulates standards as follows. For each product, a set ofengineering dl1signs is specified. For each design, the engineering analysis provides a per-unit cost, a one-time capital cost, and an energy usage. The two costs effectively determine the production costs used in Figure 3.4 and the energy usage determines the operating expense. The ManufacturerImpactModel calculates a weighted average ofthe two costs andthe energy usage for the relevant engineering designs. The weights used correspond to the relative numbers of shipments for each engineering design as determined by LBL-REM. Another and more subtle point is that markup is determined by price elasticity, and because life-cycle-cost elasticity is constant, price elasticitychanges with achange in eitherprice or operating expense. This change in markup can have an important impact on ROE. The markup discussedhere is amarkup over 

### economic variable costs, which is abroader category than the typical business definition ofvariable costs. The manufacturer markup listed in the model and the technical support document is used only to calculate the baseline model price (calculated by multiplying the baseline manufacturer cost by the manufacturer markup). This is called the calibration case in LBL-MIM. The manufacturer markup listed is 

### notused in calculating the manufacturerprices for the 1996 base case or the standard levels. In these cases, the manufacturer price is calculated from the economic markupll, which, as described above, is dependent on elasticities, discount rates, and price and operating expense changes. Thus prices at different standards levels do not exactly reflect the manufacturer cost times the manufacturer markup.Typical results ofan analysis ofa standard at a particular level might be the following: wholesale price increases 10%, sales decline 2%, revenue increases 8%, net income increases 12%, and ROE increases 0.5%. Associated with each ofthese numbers is a standarderror. The errors might be as follows: 4% on price, I% on sales, 4% on revenue, 10% on net income, and 1.5% on ROE. To interpret the prediction for ROE, one could then conclude (by checking a table of the normal distribution) that there is about a 69% chance that ROE will increase, and ,... a 31% chance that it will decrease. One could also conclude that the chance ofprofits declining by more than 2% is only 2.3%. 3.3.4.2 Short-Run Impacts In the shortestrun, capacity is fixed; however, the shortrun ofinterestis, at the shortest, approximately three years. During this time some change in capacity may occur, and demand,. apart from the change induced by standards, will change. Demand for each appliance is projected to grow by approximately 2% during the three years, so to that extent it will alleviate any tendency toward excess capacity resulting from standards.

IlPor a thorough description ofhow markups are derived and used in LBL-MIM, see Appendix C.2.I. 3-26

### In orderto simplify the analysis and to take acautious approach, the analysis has ignored the ability of the industry to actively or passively adjust its capacity relative to demand. The estimated short-run effect is what would happen if the industry converted, as a result of standards, all ofits present capacity, and ifthe demand curve did not shift except as an indirect consequence of standards. The short-run analysis is based on the analogy between a change in demand causedby standards and one caused by the business cycle. The business cycle periodically presents the industry with a fairly sharp decrease in demand that is much greater than the decrease predicted for any ofthe standards levels. This demand shortfall seems to present all ofthe opportunities for price competition that would accompany a shortfall resulting from a change in standards. Data for the last few business cycles (18 years) have been analyzed to determine the ratio between the decline in demand (industry-wide) and the induced decline in price. If, for example, the long-runprediction is for adecline in demand of2%, then, using the above figure, the short-run price could be predicted to be 0.06% (0.03 x 2%) lower than the long-run price. Actually, this isjust a first approximation, and the model does better, as follows: the short-run price response factor (SRPR) of0.03 means that the short-run price will be 0.06% lowerthan predictedwith the long-run price formula ifthe 

### actualdecline in demandis 2%. This is different from the long-run prediction of a 2% decline, because the short-run price fall will keep the long-run demand fall from fully materializing. Thus, in the short run, the actual fall in demand will be less than the long-run prediction of 2%, and the actual fall in price will be greater than the long-run prediction, but not by a full 0.06%. Short-run demand and price must be determined simultaneously, which occurs in the short-run module ofLBL-MIM. Short-runprices, profitlevels, and othervariables will gradually, overaperiodofseveral years, approach their long-run values. How long this will take depends on the industry, on the fact that the implementation of standards is announced three or four years in advance, and on how fast (and if) the demand for the product is growing. These factors are discussed in the'--'- sections on individual products. 3.3.4.3 Sensitivity Analysis Both because ofthe nature ofthe informationrequired andthe desire ofsources toprotect proprietary information, many of the data used by the model represent uncertain estimates. Therefore, the effectofthese uncertainties on theaccutacy ofthe model's predictions is analyzed. Two types of questions need to be answered. First,· how does a particular input variable contribute to the uncertainty ofthe outputs? Second, how uncertain is the estimate ofaparticular output variable?

The results are displayed in a sensitivity chan, an example ofwhich is given and explained below. Table 3.2 Sensitivity ofROE to 1S.E. Change in Control Variable, Direct Heating Equipment

These two variables are dollar values rather than percentages, and thus their value and the change in one standard error are different at each standards level. To construct the table, each control variable is first set to its normal value. Next, one at a time, each is increased in absolute value by one standard error and the change in profit is recorded. Then the variable is returned to its normal value and the next variable is tested. The matrix in the table lists the percentage point change in ROE as a result of the change of one standard error in the variable's value. The change in ROE is listed for each control panel variable and at each standard level being analyzed. Since each variable has its own standard error, the sensitivity reported in the table measures both how sensitive the model is to a change in the variable, and how uncertain the variable's value is. Note thatthe change in profitis simply the difference between long-run ROE andbase case ROE. Note also that, as expected, increasing the absolute values ofsome variables increases ROE and, for other variables, decreases ROE. The comparison ofthe various inputs' contributions to the uncertainty in ROE focuses attention on the parts of the model that should be examined most closely to determine their accuracy and on the parts where improvement in the certainty ofinput variables wouldhave the greatest payoff. Because of the differences in the sensitivities among input variables, it will generally be found that one to three ofthe inputs will dominate the model's uncertainty, in the sense that perfecting all the rest of the inputs would make only a negligible difference to the model's accuracy. 

### Alternative Scenarios Foreach appliance class andhypothetical standards level, hundreds ofdifferent scenarios are run for the Monte Carlo analysis described in a following section. However, a few scenarios that involve different demand elasticities are singled out for special attention. If the reader wishes to estimate some other scenario not reported here, he or she can often simply use the sensitivity charts. To do this, fIrst look up how sensitive ROE is to a one standard deviation change in the control variables that are changed by the proposed scenario. Then estimate by how many standard deviations the desired scenario variables differ from the primary scenario control variables and calculate a proportional change in ROE. Lastly, add the changes in ROE resulting from the different variables. This method should be reasonably accurate for changes in the control variables that are likely to be ofinterest. 

### Uncertainty ofOutputs (Monte Carlo Analysis) Outputuncertainty is most directly addressedby the Monte Carlo analysis. This analysis assigns an uncertainty to each ofthe nine control-panel input variables and then chooses a value for each based on this uncertainty. The model is then solved using these randomly chosen 3-29 Note thatfor CC.N anddVC.N the change ofone standarderror from the mean is applicable for standards level 2 only.

### Uncertainty ofOutputs (Monte Carlo Analysis) Outputuncertainty is most directly addressedby the Monte Carlo analysis. This analysis assigns an uncertainty to each ofthe nine control-panelinput variables andthen chooses a value for each based on this uncertainty. The model is then solved using these randomly chosen 3-29variables. All of the important outputs are tabulated on the Monte Carlo page of the model. These outputs are changes from the base case ofprice, shipments, revenue, net income, long-run ROE, and short-run ROE. Next, new values of the input variables are drawn from the same distribution. The model is run again and the new outputs recorded. This cycle can be repeated as many as 400 times (or more). After a sufficient number of runs, the mean and standard deviations ofeach output variable are computed. The standard deviations ofthe Monte Carlo output variables are the best estimate ofthe true uncertainty ofthe model's predictions. However, this does not mean they are absolutely reliable because they are based on estimates ofthe uncertainty ofthe inputs, and these are often not based on something as objective as the standard error ofa regression coefficient. In short, ifthe uncertainty in the inputs is misperceived, the estimate ofuncertainty in the outputs cannot be relied upon. Nonetheless, the standard errors generated by the Monte Carlo procedure are useful for the interpretation ofthe LBL-MIM outputs.

3-30Assumptions in the Analysis Assumption

• Firms maXImize revenues minus economic costs (R-EC), where EC includes the cost ofequity and all taxes.

• The life-cycle-cost elasticity of demand experienced by a single fIrm is constant. This means that price elasticity will tend to decrease with operating cost. Note also that since price elasticity is fInite, ftrms have market power.

• Costs are assumed to have two components: one fixed, and one proportional to quantity.

• Assets are assumed to be a linear function ofsales.

• The debt-to-equity ratio remains constant while the fIrm fInances any investment necessary to meet standards.

• The additional costs of parts, materials, and labor are assumed to be long-run marginal costs.

3-31 Justification This follows from the assumptions of standardeconomic theory, in which ftrms are rational proftt maximizers. There is no reason to assume that lifecycle-eost elasticity either increases or decreases with cost; thus, constancy is the base assumption.

A linear cost function approximates any smooth curve over a small region; since quantity changes very little with standards, the linear approximation should be adequate. Same as previous justification.
Finns attempt to maintain a relatively constant overall debt-to-equity ratio, which they believe is optimal. Although speciftc new expenditures (such as those induced by standards) may be financed primarily by debt or by equity, in the long run the debt-to-equity ratio will be restored to its desired value.
. These costs are proportional to production except for cases in which there are discounts for large quantity purchases. Industry sources state that at the scales of production under consideration, these discounts are very nearly exhausted. Assumptions in the Analysis Assumption

• Any fall in demand caused by standards (because of a price increase) will affect prices in the industry by the same amount as a normal fall in demand experienced during the business cycle.



### Outputs of the LBL-MIM Justification Although industry informants have stated that one-time capital costs will be proportional to the productioncapacity of the plant in question, it seems inevitable that there will be some associated engineering costs that are not These will be long-run fIxed costs.
To the extent that a normal demand shortfall reduces the fIrm's short-run marginal cost, the demand decrease caused by standards will be indistinguishable. The crucial assumption here is that the business cycle does not influence the consumers' elasticity of demand. There is no evidence one way or the other on this.

The LBL-MIM tracks fIve essential output variables, with emphasis on ROE. The otherfour variables are price, sales, revenue, and net income. Base case and short- and long-run values of these variables are reported on the control panel. In addition, LBL-MIM constructs an output table that shows the long-run values of the variables at each of the standard levels under consideration. LBL-MIM also produces a simplifIedincome statement As part ofits algorithm, it calculates the markup from manufacturers' costs to consumer purchase price. The purchase price is used in the calculation of price-effIciency curves, the life-cycle-cost curves, and the calculation ofpayback periods, and throughout the LBL-REM. All ofthese values are estimates that necessarily reflect some uncertainty. Estimates ofthese uncertainties and identification oftheir sources comprise another set ofmodel outputs. Under each estimate ofone ofthe five main output variables, the output table displays that variable's change from its base level and the standard error ofthe estimate ofthat change. The LBL-MIM also computes the effect on ROE of a one-standard-deviation change in each of the control variables. This is reportedfor each standardlevel in a sensitivity chart, designed to help discover the source ofuncertainty in the output variables.

It contributes to quantifying energy savings by determining the reduction in fossil fuels used for electricity generation; this reduction also serves as input to the Environmental Assessment. By calculating utility avoided costs, the Utility Analysis provides marginal electricity costs to be used in evaluating the societal benefits ofstandards. The Utility Analysis also quantifIes impacts on the electric utility industry's need for new generating capacity. Finally, the Utility Analysis calculates net impact ofstandards on utility revenues. Appendix E of this volume contains more information on the model and data used to perform these calculations. TheUtility Analysis adopts the convention thatthe value ofelectricity savingscanbe broken down into energy (or marginal cost) savings and reliability (or capacity) savings. The energy impactmeasures production costs avoided by reducedelectrical demands, valued atthe marginal energy costs ofthe utility. The reliability impact measures the value ofreduced loads during system peak periods, which is, by convention, valued at the cost ofa combustion turbine. This convention is justified in Appendix E. The analysis calculates the avoided costs per.kWh of energy saved. These values are used to calculate societal benefIts from reduced electricity consumption. The utility impact model calculates avoided energy costs based on a disaggregation of the generation fuel mix to the National Electric Reliability Council (NERC) regions and a simplified load duration curve for each region. First, the model allocates national electricity savings forecast by the LBL-REM to NERC regions in proportion to their 1980 consumption ofheating, cooling, and baseload energy. For the three product types under consideration, only baseload energy is used. The fraction ofthe electricity thatwouldhave to be generated atthemarginfrom oil and gas is calculated from total regional oil and gas generation and the simplifIed load duration curve. Projected utility natural gas and coal prices, weighted by the oil and gas marginal fraction and the non-oil and gas marginal fraction, respectively, are used to calculate utility marginal energy costs during the forecast period. The avoided-capacity cost calculation in the model is based on conservation load factors (CLFs) for the energy savings attributable to the standards, as well as the cost ofa combustion turbine. A conservation load factor is defined as the average load savings of a conservation measure (in kilowatts) divided by its peak-load savings. The peak savings are averagedover an 3-33

A conservation load factor is defined as the average load savings of a conservation measure (in kilowatts) divided by its peak-load savings. The peak savings are averagedover an 3-33on-peak period from 8 A.M. to 8 P.M. This wide on-peak period yields a conservative estimate for peak-load savings that accounts for coincidence with system peak demand. The CLFs, calculated using annual average appliance load curves from Southern California Edison Company data, are used to characterize the peak demand savings of a conservation measure. (4) They are used to convert the reliability value ofthe standards into the per kWh values described above. The analysis assumes that the load shapes of each one of the eight product types do not change as these appliances are made more efficient. The NERC forecasts of capacity requirements for each region are used to account for regional variations in reserve margin. IfNERC predicts an adequate reserve margin in aregion for a given year, no reliability value is given to the peak load savings in the region. The net revenue loss is equal to the difference between the revenue reductions and avoided costs. Revenue reduction is calculated by multiplying the change in electricity consumption by the average utility rate. Avoided costs are calculatedfrom the change in electricity consumption multiplied by the per-unit, avoided costs. The inputs neededfor the utility impact model include electricity savings, conservation load factors, state-levelutility fuel prices, average electricityprices, appliance saturations, efficiencies, hours-of-use, and electricity generation by fuel type and capacity need by NERC region. The outputs ofthe analysis are the fuel savings, the reduction in the needfor new generating capacity, the net change in revenues, and the avoided energy and capacity costs for heating, cooling, and baseload appliances per million Btu of resource energy. These marginal costs are used to calculate societal costs and benefits of standards.

3-34Assumption



### • The analysis calculates the period during which oil and gas or coal are the marginal fuels for electricity generation basedon a simplifiedloadduration curve (LDC) for each NERC region. It therefore assumes that this LDC accurately reflects the distribution of fuels on the margin.

• The oil and gas fractions (OGFs) calculated for all the NERC regions remain constant throughout the analysis period.

• Energy savings accrue in each region in proportion to the region's consumptionof heating, cooling, and baseload energy in 1980.

3-35 Justification 

### There is little information by NERC region on which fuels are marginal. Since NERC supplies the total amount of fuel burned for generation, a method is neededto converttotal generation into an estimate of marginal generation, and using an LDC is the usual way to derive such an estimate. Because oil and gas are most expensive, they will 

### be used by utilities to meet the peak load-hours; hence, oil and gas are assumed to be at the top ofthe load duration curve. The other fuel on the margin is coal, since nuclear and hydro resources are usually base-loaded. Constant OGFs are assumed to simplify computation. The OGFs are calculated using the simplified LDCs described above and by averaging NERC forecasts of the total amount of oil and gas generation for the years 1990 to 1995. There are no forecasts for the amount of oil and gas generation after 1995. Because these calculations are highly uncertain, and because no other forecasts are available, the analysis assumes constant OGFs. This approach is an approximation made necessary by insufficientinformation and for computational convenience. Information is available on average saturations and appliance efficiencies, by state, that can be aggregated to NERC regions. Assumption

• The NERC forecasts of changes in adjusted reserve margin are accurate.

3.3.6 Life-Cycle Cost Analysis Justification Different generating units have different heatrates, but the extent ofthis variation for utility generating systems in different NERC regions has notbeen calculated. A 10,000 Btu/kWh heat rate is typical for many different types ofgenerating units.
The NERC forecasts are widely accepted. They are the only forecasts of adjusted reserve margin at the regional level.

One measure ofthe effect ofproposed standards on consumers is the change in operating expenses as compared to the change in purchase prices. These changes are quantified by the difference in life-cycle costs between the base and standards cases for the appliance classes analyzed. The LCC is the sum ofthe purchase price andthe operating expense discounted over the lifetime ofthe appliance. Itis calculated at the average efficiency for each class in the year standards are imposed using real consumer discount rates of2%, 6%, and 10%. The purchase price is based on the factory costs in the Engineering Analysis and includes a factory markup plus a distributor and retailer markup. Maintenance and installation costs are included, when appropriate. The operating expense is calculated using the unit energy consumption data in the LBL-REM. Energy prices and appliance usage are taken from the results ofthe LBL-REM. The life-cycle cost analysis also examines the payback periods and the cost of conserved**energy,~,** associatedwith the standards. Details ofthe LCC calculation may be found in Chapter4 ofeach product-specific volume. An additional measure of economic impact, payback period, is useful in evaluating the impacts on consumers ofefficiency standards. The paybackperiod measures the amountoftime it takes to recover additional investment in increased efficiency through lower operating costs. Numerically, itis theratio ofthe increase in purchaseprice between the base and standards cases to the decrease in annual operating expenditures. Both the numerator and denominator ofthis expression are evaluated at the average efficiency in the year standards come into effect and at energy prices in that year.

3-363.4 SENSITIVITY ANALYSIS Sensitivity studies are performed to determine how changes in technical and operational parameters affect key engineering and economic indicators used in the evaluation of appliance standards. This makes itpossible to place bounds on the uncertainty in the results ofthe analysis and to gain an understanding ofwhich variables are most important in producing these results. Sensitivity analyses are developed in a series ofdistinct steps. For each computer model in the analysis, critical input parameters are identified and reasonable ranges of variation are determined. The sensitivity ofthe model to changes in the value ofeach important parameter is then estimated by running the model for the base case and standards cases. The significance ofthe results is assessed in terms ofthe magnitude ofchange in each model's outputs. Sensitivity runs are made with the LBL-REM to explore the effects ofuncertainty in the equipment and operating cost ofthe products being analyzed. The costs ofthe baseline unit as well as the incremental costs of design options are varied. Other sensitivity runs examine alternative efficiency trends in the absence ofnew standards. Sensitivity analysis ofthe results ofthe LBL-MIM is conducted mainly from a sensitivity chart that reports the sensitivity of ROE to each of the nine control variables. Because the LBL-MIM is a non-linear model, the effects of these input uncertainties may not be additive. A Monte Carlo analysis addresses this problem by computing standard errors, which are displayedin the outputtable. For each control variable, the Monte Carlo section randomly picks a value near the best estimate ofits true value. As a result, the outputs ofMonte Carlo vary from run to run. Afterfinishing a batch ofruns (typically 100 to 400), the LBL-MIM calculates means and standard deviations for the five main output variables. The results of the sensitivity analyses are examined to extract two types of information. First, the base case runs ofthe model are analyzed to determine the sensitivity ofthe forecasts to exogenous variables and assumptions. Second, the sensitivity analysis of the impacts of**~~­** standards is performed by examining the**differenc~s** between the base and standards cases. A variable that affects the two cases similarly will have little effecton theimpactofstandards, even though it might have a significant effect on the absolute forecasts. The primary interest in the second type of sensitivity analysis is in variables and assumptions that affect the two cases differently. The sensitivity analyses ofthe impacts ofstandards are discussedin the chapters on these impacts. The EPRI COMMEND sensitivity run for the fluorescent ballast analysis was the "HighEfficiency baseline." Standards analyzed under the reference baseline ("Base Case") show the savings potential if other existing incentives (utility DSM, EPA's Green Lights, and FEMP's Relighting Initiative) are removed from the market after 1995. Standards analyzed under the "High-Efficiency baseline" show the effects of the persistence of existing incentives programs after 1995. The savings for the sensitivity run are less than those for the reference case, reflecting the smallermagnitude ofavailable savings to be captured by standards. See Volume B, Chapter 2, for further explanation ofthe commercial sector baselines. 3-37 3.4 SENSITIVITY ANALYSIS Sensitivity studies are performed to determine how changes in technical and operational parameters affect key engineering and economic indicators used in the evaluation of appliance standards. Thismakesitpossibletoplacebounds onthe uncertaintyinthe results ofthe analysis and to gain an understanding ofwhich variables are most important in producing these results. Sensitivity analyses are developedin a series ofdistinct steps. Foreach computermodel in the analysis, critical input parameters are identified and reasonable ranges of variation are determined.

### CHAPTER 4. INDUSTRY PROFILE FOR LBL-MIM ANALYSIS

This section begins by examining housing starts and appliance saturation rates, with the primary focus on annual unit shipments for each ofthe analyzed products. It 

### then presents a briefdescription ofmarket shares followed by a discussion ofmergers and acquisitions in these industries, and fmally a comparison ofconsumer and producerprice indices. 4.1 DEMAND 

### Units ShippedandHousing Starts One of the primary components driving the demand ofmost appliances is housing starts. Although the changes in shipments ofappliances are not entirely the result ofchanges in housing starts, housing starts can be used to predict shipments ofmost appliances for two reasons. First, almost every new house requires a new set ofappliances, so fluctuations in housing starts cause fluctuations in shipments of most common appliances. (In fact, most of the fluctuation in shipments ofproducts being analyzed can be attributed to the fluctuations in housing starts.) Second, housing starts are a goodindicatorofthe strength ofthe economy as a whole. Ahealthy new-housing market is likely to correspond to a healthy economy, and a healthy economy encourages replacement and discretionary purchases ofappliances. Therefore, there is generally a strong correlation between new-housing starts and appliance shipments. For similar reasons, there are strong (ifnot even stronger) correlations betweenmobile home production and the sales ofmobile home furnaces, and between new commercial floor space and fluorescent lamp ballast shipments. Figures 4.1 through 4.8 show annual shipments compared to housing starts between 1970 to. . 1989 for most products. Figure 4.7 shows mobile home furnaces versus new mobile home production. Figure 4.8 shows annual fluorescent lamp ballast shipments and new commercial construction between 1980 and 1989. There is a strong correlation between housing starts and sales ofmany ofthese appliances, which is seen clearly in the nearly exactparallel ofthe graphs in the figure. Other factors such as age of the current stock of appliances, purchase prices, fuel costs, consumer incomes, and climate conditions have varying degrees ofimportance in determining shipments ofthe various products covered by the National Appliance Energy Conservation Act of 1987 (NAECA). Further, some appliances have strong demand in the replacement market or in the aftermarket, and thus would be less correlated with new housing starts. Some of these factors are used by the LBL-REM in predicting appliance shipments in the base case and new standards case. The Manufacturers ImpactAnalysis uses the LBL-REM estimates in its analysis offinancial impacts on manufacturers.

### Units ShippedandHousing Starts One of the primary components driving the demand ofmost appliances is housing starts.

### As expected, most ofthe appliances show a strong correlation with housing starts. Several interestingpoints emergefrom these graphs. In the case ofdirectheating equipment (Figure 4.2), there is a strong correlation with housing starts from 1969 to 

### 1979 for the total (primarily composed ofwall furnaces with lesser correlations for room heaters). From about 1978 to the present, the shipments ofdirect heating in general (and floor furnaces in particular) have been declining. Meanwhile, the shipments ofcentral heating equipmenthave beenrising andprobably have been absorbing the market share ofdirectheating equipment. This observation corresponds with reports from the industry which also state that the primary market for direct heating equipment is now replacement rather than new sales. The explosive growth in microwave ovens is displayed in Figure 4.3. After a slow period ofgrowth in the late 1960s to early 1970s, the popularity ofmicrowave ovens increased steeply in the 1980s, probably due in part to the greater convenience, improvement ofthe technology, and lowerprices. In fact, the saturation rate ofmicrowave ovens rose from 1% in 1973 to 66% in 1987, according to industry trade sources. The sales ofroom air

### conditioners have little correlation with housing starts. We expectthat this is because room air conditioners are bought primarily in the aftermarket and- have a strong seasonal component in theirpurchase. Similar to microwave ovens, television sets have experienced explosive growth over the twenty years as noted in Figure 4.5. In particular, color televisions have greatly outstripped the sales ofblack-and-white televisions. 

### Appliance Saturation Rates The saturation rate is the percentage ofhomes that own a particular appliance. Tables 4.1 and 4.2 list the saturation rates for the various analyzed appliances in selected years during the past 20 years. Note that the data do not reflect the fact that some homes have more than one-----· appliance ofa particular type. In general, ifmost homes own an appliance but few homes have

-more than one unit, we expect that the appliance will have arelatively low elasticity ofdemand

because the appliance is usually considered a necessity. This observation corresponds with the relatively low price elasticity ofcertain products such as waterheaters andranges and ovens and the higher price elasticity ofproducts such as televisions and microwave ovens.

### 4.2 SUPPLY Market concentration Market concentration is the extent to which market share 

## IS controlled by the largest fIrms in an industry. Table 4.3 shows the market concentration for the products according to the degree ofthe market controlled by the two, four, and five largest producers in each industry. 4-11

### Most of the products show a high level of market concentration. With the exception of microwave ovens and television set manufacturers, the markets concentration of the top five producers are at least 85%. The largest producer controls from 40% to more than 50% ofthe market for each ofthese products. Market concentration plays a part in the analysis because it 

### may indicate the existence ofmarket power12 

### in a particular industry. Firms with the largest market shares may have some market power, a factor that affects the markups used by these finns both in the base case and the standards case.

Mergers and acquisitions have two purposes: First, they produce large corporations with the financial resources and stability to be successful in an increasingly competitive market Second, mergers and acquisitions mean manufacturers can have a complete line ofhome appliances for product diversification and can therefore offer a complete set ofappliances to consumers, an important feature in the builder market. There is increasing worldwide competition in the major appliance market, so mergers or acquisitions are likely to continue.

### 4.4 PRICES Appliance prices have, on average, risen more slowly than aggregate indexes measuring consumer and producerprices, with direct heating equipment being an exception, and television sets showing a strong drop in the 1980s. The appliance industry has a long history of price stability even through fluctuations in the business cycle. Despite increased energy and componentprices during the 1970s and 1980s, the industry has, through increasedproductivity, kept price increases lower than increases in the Consumer Price Index (CPD. In recent years, the industry has made a strong push toward automation to keep costs down, spending hundreds ofmillions ofdollars to automate production facilities. Figure 4.19 shows the Producer Price Index (PPI) for all commodities and for household appliances for the years 1984 to 1991. The PPI for household appliances increased about half as much as the PPI for all commodities. Figures 4.20 to 4.25 show the real PPI for various product groupings compared to the CPI and the household appliance group as awhole. The real PPIfor eachproduct groupingis defined as the PPI for thatproductgrouping, holding the overall PPIconstant at 1982

## = 100. In otherwords, this figure indicates the relative increase ordecrease in theprice index ofa product grouping, using the PPI for all commodities as the yardstick. The subsequent figures and their products are

## CHAPTER 5. DEVELOPMENT OF BASE CASE FORECASTS

Analyzing impacts of federal energy efficiency standards requires comparing projected U.S. residentialenergy consumption with andwithoutthe standards. The cases without standards are referred to as base caseprojections. These base caseprojections are comparedto projections of conditions that would be likely to prevail if standards were enacted (see Chapter 3). The difference between the two projections is defined as the impact of standards. Projections are made for a number of demographic, economic, and energy variables, which hold true for all end uses, including energy prices, household income, housing stock, housing starts, mix ofhouse types (single-family, multifamily, mobile homes), and building shell thermal characteristics. Additional (product-specific) variables, described in Chapter 2 ofeach product-specificvolume, include appliancepurchases, equipmentprices, unitenergyconsumption, and aggregate residential energy consumption by fuel type. 

### 5.1 ECONOMIC AND DEMOGRAPHIC DATA: RESIDENTIAL The LBL-REM (described in Volume A, Appendix B) is used to derive projections of residential energy demand. These projections are dependent on assumptions about future years, including the size and age distribution of the population, number of annual housing starts, disposable personal income, and energy prices. These data are described in Tables 5.1 through 5.6. (Economic data specific to each product, such as equipment price, initial market shares, elasticities for market shares, efficiency choices, and usage behaviors are described in Appendix C ofeach product-specific volume.) 

### 5.1.1 Population Projection Thepopulation projection for the U.S. is based on Bureau ofCensus data to the year2010 (10). The population projections are consistent with those used by DOE in projecting energy prices. Projections for later years are obtained by extrapolation, assuming that the annual rate of increase in population is at 0.5% per year from 2010 to 2030. 

### 5.1.2 Occupied Households The number and type ofoccupied households for the base year (1980) are from the 0.1% Public Use MicroSample (PUMS) ofthe 1980 Decennial Census. The population projection is used to estimate the housing stock in each state each year, as described in Appendix B.

. Electricity prices are further adjusted to reflect differences in effective price by specific end uses. Table 5.6 shows multipliers for obtaining effective prices for space heating, water heating, air conditioning, and other end uses from the average sector prices in Table 5
.5. 5-3These multipliers capture regional differences in residential rates and appliance holdings, as well as effects ofrate structure. (For example, ifelectric heat is common in areas with lower residential rates, then the effective rate for electric space heating is lower than the average residential rate. Also, ifthe block structure offers decliningrates for increasedconsumption, then end uses associated with higher consumption, including space heating, will have lowereffective rates.) The multipliers are derived from the 1987 Residential Energy Consumption Survey.

5.2 ECONOMIC AND DEMOGRAPHIC DATA: COMMERCIAL EPRI COMMEND (described in Volume A, Appendix B) provides projections of commercial energy demand. These projections depend upon commercial floorspace, GNP, and energy prices. Appendix C ofVolume B describes the inputs specific to lighting. 5.2.1 Commercial Floor Space Projections 

### Floor Space Data Table 5.7 shows the forecasted total U.S. commercial sectorfloor space (including federal buildings) by building type used for this analysis, based on data developed by Pacific Northwest Laboratories (PNL) (16). Floor space growth drives the overall growth in demand for energy services- in the COMMEND model. Floorspace values given by EPRIin the COMMEND defaultinputfiles are slightly lower than the values published in the AEO 1992 (17), the NBS (18), and the values used by PNL. Because these other sources are in close agreement, the PNL floor space data series was chosen in this study (as it provides the most detail). PNL data give the vintages ofcurrently existing commercialbuildings. The survival functions specifiedin COMMEND characterizetheretirement rate ofbuildings and are used to estimate annual additions from 1920 to 1989. For the future, the growth rate of total commercial floorspace is related to the Gross National Product (GNP) growth rate through the regression equation calculated by PNL, which is based on data for 1963-1986.

The GNP forecasting is based on DRI numbers (to the year 2000) published in the 1987 ABO (Case A). After the year 2000, a GNP growth rate of2.1% per year is assumed (based on ABO 1992 projections), which yields a 1.8% annual growth in floor space. This total forecasted figure is distributed to building types based on a fixed ratio (the average of the last three years' additions distribution) and is kept constant throughout the forecasting period. By the year 2030, 75% (98 billion sq ft) ofthe commercial floor space will have been built after 1986. All buildings, however, will have an opportunity for lighting system changes by 2030.

Fornatural gas prices beyond2010, theprice trajectoryfrom the NationalEnergy Strategy (NBS) (9) is used, scaled to the ABO 1992 price in 2010. This price path is based on output from the FOSSIL2 partial equilibrium model and incorporates information about the supply/demand balance for natural gas. The growth in natural gas prices is expected to flatten out in 2015, according to the NBS prediction. The default input files ofCOMMEND use the fuel oil price as an indication ofthe price level ofpetroleum products. This is improved by defming a mix ofproducts (distillate fuel, kerosene, LPG, and residual fuel) and calculating a price index for this mix. The consumption levels given in the State Energy Data Report, Consumption Estimates 1960-1989 (SEDR),(21) for the year 1989 are used to calculate the contribution ofeach product to the mix. Itis assumed that propane represents all ofLPG, fuel oil represents all ofthe distillates, and all ofthe residual oil used in the commercial sector is oflow sulfur content.

## APPENDIX A. UNCERTAINTY ANALYSIS FOR ENERGY EFFICIENCY

Many oftheinputs to the calculations ofenergy savings for each design optionhave some degree of uncertainty. This uncertainty of the inputs affects the level of confidence in the estimate ofenergy savings for design options. As design options are combined, the effects of the uncertainty on the inputs are also combined, so that the uncertainty in the energy savings becomes larger and larger. In order to understand the effects that the uncertainty of input values had on the calculation ofenergy savings, arisk-analysis program (22) 

### was used to quantify the**un~ertainty.** 

### Therisk-analysis program was an add-in to the spreadsheets used to generate the cost/efficiency tables shown in the TSD (See Figure A.I.) It allowed the inputs to the calculations to be specified by an assumed distribution of values with associated probabilities. After the probabilities were specified, the energy-savings spreadsheet was recalculated several hundred times, randomly choosing a value from each distribution. The selection was done so that the distribution ofinput values chosen matched the probabilities specified in the input distribution. The baseline was assumedto be exactforpurposes ofthis study, therefore no distribution was applied to any ofthe inputs on the baseline models. The uncertainty on inputs for combined or stackeddesign options included, orwere appliedon top of, the uncertainties ofprevious design options. Often different design options affected different parts of the energy consumption calculations. An example ofthis would be applying heattraps to a gas-fired storage waterheater and then applying a submerged combustion chamber. The heat traps reduce the standby loss, while the submerged combustion chamber increases the recovery efficiency. In these cases, the uncertainties from previous design options were used in the calculations, even though that part ,--- ofthe calculation was not being changed by the current design option. The results of the uncertainty analysis were reported only for the maximum technologically feasible design options. These results include the uncertainties ofall the design options that were applied before the maximum-technologically feasible design option. Theupper and lower values reported for the uncertainty ofthe efficiency indicator span the middle 95% of all values resulting from the uncertainty analysis. For room air

A-IMost ofthe input values were assumed to have a normal distribution, with the selected value being the mean of the distribution. The standard deviation of the distribution was then specified as the difference between the largest and/orthe smallestvalues consideredpossible and the mean. The distributions were typically truncated at two standard deviations from the mean. This truncation excludes the smallest 2.28% and the largest 2.28% ofthe possible values in a normal distribution. This was done to eliminate potential outliers that could unnaturally skew the results.
