# Summary

Thepassage ofthe 1992 Energy Policy Act (EPAct) (42 USC 13201)brings commercial equipment under the scope offederal energy efficiency regulations for the first time. Categories ofequipment coveredby these regulations include commercial packageheating and air-conditioning equipment,

warm air furnaces, packagedboilers, and hot waterheaters. In setting standards for these equipment categories, minimum efficiency levels arebased onvoluntary standards promoted by the American Society ofHeating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) in the document entitled Energy Codefor CommercialandHigh-RiseResidentialBuilding 

### (ASHRAE/IES 90.1-1989) (ASHRAE 1993). EPAct further requires that ifthe ASHRAE standards are amended, the Secretary ofEnergy shall establishan amended national standard at the minimum level specified in the amended ASHRAE standard, unless amore stringent standard canbe shownto result in significant additional energy savings, and is bothtechnologically feasible and economicallyjustified. A revised ASHRAE standard is currentlyunderdevelopment, and in compliance with EPAct, the U.S. Department ofEnergy (DOE) has undertaken an evaluationofthe standards development process.

This report, preparedfor DOE, Office ofCodes and Standards, as part ofthe Commercial Equipment Standards Program at Pacific Northwest Laboratory, specifically addresses the equipment cost estimates used to evaluate the economic impacts ofrevised standards. Adatabase including commercial equipment listprices and estimated contractorcosts was developed, and through statistical modeling, estimated contractorcosts are relatedto equipment parameters includingperformance. These models are thenusedto evaluate cost estimates developedby the ASHRAE 90.1 Standing Standards Project Committee, which is in theprocess ofdeveloping arevised ASHRAE 90.1 standard. The database will also be used to supportfurther evaluationofthe manufacturer and consumer impacts of standards. Cost estimates developed from the database will serve as inputs to economic modeling tools, which will be used to estimate these impacts.
Preliminary results suggest that listpricing is a suitable measure from which to estimate contractor costs for commercial equipment. Models developed from these cost estimates accurately predictestimated costs. Themodels also confirm the expected relationships between equipment characteristics and cost. Cost models were developed for gas-fired and electric water heaters, gas-firedpackaged boilers, and warm air furnaces for indoor installation. Because ofindustry concerns about the use of the data, information was not available for the other categories ofEPAct-covered equipment. These

concerns must be addressed to extend the analysis to all EPAct equipment categories.

# 1.0 Introduction

If

### the economic impacts ofcommercial equipment efficiency standards are to be fully evaluated, all costs that are incurred inpurchasing and operating the equipment over its assumed life must be estimated. This reportprimarily addresses equipment purchased cost estimates for bothlow- and highefficiencyunits andthe appropriate performance measure(s) for the equipment. When the equipment cost datawere developed, other information relevant to the life-cycle equipment costs was also available. Where appropriate, this information is discussed, especially when it relates to equipmentpurchased costs and equipment operating costs.

The analysis relies primarily onadatabase ofequipment cost and performance information. A partial versionofthis database is included inAppendix A, withmanufacturer-specific information and

some cost dataexcludedto protectthe proprietary interests ofthe manufacturers. This database was developed from list price information suppliedbymanufacturers ofcommercial equipment; catalog data

onthe features and characteristics ofthe equipment; and performance information derived from a variety ofsources including the manufacturers, equipment catalogs, equipment directories, and other databases. 

### In addition, the manufacturers were asked to supply estimated multipliers for converting list prices to wholesaleprices, allowingprice comparisons between companies. Contractorpricing is estimated from wholesaleprices assuming adealermarkup of 10%. Finally, consumer costs are estimated assuming acontractormarkup of25

### %, which does not include the cost oflaborfor equipment installationortheperipheral equipment necessary to install the equipment. The two cost measures held in the database are listprice and estimated contractorprice.

The database is usedto develop estimates ofthe baseline contractor costs for standard-efficiency equipment as well as the incremental costs for high-efficiency equipment. Because the database relies

on information about existing equipment, it reflects costs associated withthe actual features and characteristics ofboth standard- and high-efficiency equipment currently available on the market. As such, the datamay not cover the entire spectrum oftechnologically achievableperformance. The results also reflectmarket factors that affect equipment costs beyondthe actual costs that are associated with the productionand distributionofthe equipment. The cost estimates areused to evaluate cost information generatedby the American Society ofHeating, Refrigerating and Air-Conditioning Engineers (ASHRAE) inthe development ofa revised ASHRAE Standard 90.1.

The database in Appendix A includes information onwater heaters, hot water storage tanks, packaged boilers, and warm air furnaces. Information was requested from manufacturers ofheating, ventilating, and cooling (HVAC) equipment; however, there was an extreme reluctance to providethese data, especially among the major manufacturers. A formal request for data was presented throughthe Air Conditioning and RefrigerationInstitute (ARI) to its members, which include most ofthe manufacturers ofcommercial HVAC equipment. This request was turned$lown. The Gas Appliance Manufacturers Association (GAMA) also formally requested that the U.S. Department ofEnergy (DOE) desist from current cost datacollection efforts until after the ASHRAE analysis is completed. As a result,

1.2

# 2.0 Background

Several potential sources ofcost and performance information are available for commercial equipment. The following chapterdiscusses some ofthe strengths and weaknesses ofthese information

sources and also discusses how the data canbe used to relate equipment costs to equipment characteristics.


## 2.1 EvaluationofCostData

Accurately evaluating average commercial equipment costs is difficult. Competitive pricing at the wholesale, dealer, and contractorlevels leads to wide variation in consumer costs for aparticularpiece ofequipment. Comparing equipment pricesbetweenmanufacturers requires that a consistent measure ofcostbe identified.



### 2.1.1 MarketEffectson CostData Consistency

At the manufacturing level, costs are typicallymeasured as "standardcosts," which reflect the estimated cost (not including sales and general administration costs) to produce atypical model. A change in standardcosts over agiventime period is referred to as variance, where apositive variance represents averageproduction costs above the expected standard cost. Ifthe variance is generally small with respectto standard cost and the standard cost is consistently defined across agiven sector ofthe manufacturing industry, the standard cost would be an appropriatemeasure ofmanufactured cost. Unfortunately, manufactured cost information is very closely guarded. This is partly due to the fact that amanufacturer's competitors canobtaindetailed information about its products simply by purchasing them. Therefore, productioncost information remains one ofthe few competitive secrets that can be maintained. Evenifstandard costs are a consistent measure ofequipment costs between companies, this information is difficultto obtain.

Manufactured costs can also be expected to fluctuate substantially as a result ofshort-term market conditions. Equipment manufacturers rely to avarying extent on suppliers to provide components for the equipment. As demand for equipment rises, the manufacturers may turn to secondary suppliers of components to meet short-termdemands. This may, in turn, result in higher component costs, though the essential characteristics ofthe equipment remain unchanged. In acompetitive market, these costs may not be passed onto the consumer and may not be reflected in retail equipment prices.

Difficulties also occur in the collection ofconsistent cost information at adefined point in the equipment distribution chain. This happens primarily because ofthe variety and complexity ofdistributionmechanisms found in the commercial equipment market. As an example, consider two extreme
cases ofdifferent marketing systems. In one system, equipment is marketed through distributors who purchasethe equipment based on apublished price list. The actual pricepaid for the equipment is discounted from the published pricebased on the dollar volume ofsales, the number ofmodels stockedby the distributor, and the terms ofthe sale (cash paid in a specific time frame after shipment). Also,

2.1

### these publishedprices may vary by region. In another system, a small company that manufactures a low volume ofhigh-efficiency equipment may market that same equipment directly to consumers. Identifying aconsistent cost measure for comparing equipment from these two types ofcompanies is difficult.

Because consumer costs for equipment are inmany cases the desiredmeasure, itis also possible to try to collect this informationdirectly. However, commercial equipment is typically not sold at aretail level, making consumer cost difficult to collect. Commercial equipment is usually purchased and installed by acontractor who charges the consumer for the cost ofthe equipment plus some markup to
cover overhead andprofitfor the project. Contractorsbasethis markup onthecharacteristics ofthe project and the relationship to the customer. In general, the greaterthe level ofcompetitionin an area and the lowerthe level ofrisk involved intheproject, the less the equipment will be marked up. Estimated markups canrange from less than 15

### %to greaterthan 50

### %, thus heavily impacting the actual

consumer cost forthe equipment. Because ofthe factors involved inprojectbidding, it

### is generally difficult to obtainequipment cost estimates from contractors without specifying the exactdetails ofthe project.

Otherpotential sources ofconsumer cost datafor commercial equipment areutility rebateprograms that offer incentives to customers based onthe cost ofthe equipment. Ifsufficient information is recorded inthese programs, itwould serve as a source ofdata on actual equipment costs at the consumerlevel. Anevaluationofthis data source suggests, however, thatthe quality and quantity ofcommercial equipment cost data availablethroughrebateprograms is limited and, in many cases, may be consideredproprietary.
Finally, equipment distributors canprovide cost information for equipment at the contractor level. These costs will reflect all ofthe variations found inthe distributionchain, including regional factors that affectprice. Estimating national average values, however, makes itnecessary to request datafrom

awide number ofdistributors. Collecting information from distributors also has otherlimitations. First, prices chargedby agivendistributor may vary depending on the relationship with an individual contractor. Second, contractorcost informationmay be considered proprietaryto disguise the variable rate structurebetweenclients. Third, the collectionoflarge quantities ofinformationthroughthis method wouldbe difficultbecause no publishedcontractorcosts are available. Thus, while distributor pricing may bethe best information available for estimating consumer costs, it

### wouldbe difficult to develop a largedata setbased onthis source.

Theprimary cost data sourceused in this analysis was manufacturer-supplied listpricing. Because list prices are not necessarily comparable betweenmanufactures, list price information was converted to estimated wholesaleprice where wholesaleprice is defined as the pricepaidby adistributorfor the equipment. Two methods were used to convert list prices to wholesaleprices. Whenpossible, equipment manufacturers were asked to provide amultiplier for calculating wholesale pricefrom list price. Lacking manufacturer estimates, dealers were contacted for actual contractorprice quotes, and these quotes were averaged to identify the relationship between listprices and contractorpricing. Estimated

2.2

### average dealer and contractormarkups werethenused to convert these costs to consumer costs. A similar multiplier canbe used to estimate manufacturer costs.



### 2.1.2 SpecificityofEquipment Characterization
Accurately measuring the cost ofcomparable pieces ofequipment requires a detailed specification ofthe properties ofthat equipment. Withoutthe ability to control for equipment features, any betweencompany comparison ofequipment costs is impossible.

As an example, consider some common features ofcommercial electric water heaters. Frequently, theseunits canbepurchasedwitheitherimmersion orsurface thermostats. The cost premium for an immersion thermostat model may be as much as an additional 30

### %overthe cost ofa surface thermostatmodel. Without knowledge ofthe thermostat type, it is clearly risky to compare the costs oftwo otherwise similarunits. When incremental cost estimates are made from costs for existing equipment, it is important to understand the features associated with the equipment.

Baseline equipment cost estimates also affect the outcome oflife-cycle cost calculations. As first costs for equipment escalate, the impact offuel savings onthe life-cycle cost diminishes. An accurate assessment ofaveragebaseline equipment costs requires not only anunderstanding ofcommon equipment features and costs, but also anunderstanding ofthe market penetration ofthese features.


## 2.2 EvaluationofPerformanceData

Performance informationplays an integral role inthe estimation oflife-cycle consumer costs for commercial equipment. 

### In this type ofanalysis, incremental costs for high-efficiency equipment are essentially weighed against the value offuel savings overthe life ofthe equipment. Ifthe presentvalue offuel savings is greaterthanthe presentvalue ofincreased capital orother costs, thenthe life-cycle cost is lower athigher levels ofefficiency,justifying amore stringent standard. While life-cycle cost minimization is only one ofmany possible decision rules in any life-cycle cost assessment, the actual life-cycleperformance ofthe equipment has an important effect onthe estimation oflife-cycle cost.

Standardmeasures ofperformancehave beendeveloped for commercial equipment by avariety ofgroups and agencies, including DOE, ASHRAE, American National Standards Institute (ANSI), and Underwriters Laboratories (UL). These standards describe adetailed test situationinwhich the performance ofa specificpiece ofequipment is measured in the laboratory. The standards are designed to ensure consistentratings ofequipment producedby different manufacturers. Performance testing for commercial equipment primarily focuses onthe steady-stateperformance, however, which typicallydoes not reflect the actual seasonal performance ofthe equipment. Thus, evaluation oflifecycle costsbased on steady-stateperformance measures does not accurately reflect the actual fuel**consu~ption** 

### and fuel costs associated with equipment operation.

This issue is particularlypertinent when evaluating high-efficiency equipment. Achieving such high efficiencies makes it necessary to depart radically from conventional design parameters.

2.3

### Examples ofsuch types ofequipmentinclude modulating condensingwaterheaters andboilers, pulse combustionfurnaces andboilers, and directcontactwaterheaters. Standardtestprocedures applied to thesetypes ofequipment may grosslyunderestimate oroverestimatethe annual fuel consumption, and thusfuel costs.

As an example, considerthemodulating waterheater referred to above. Under steady-state conditions atmaximum-rated capacity, thetestedthermal efficiency (ANSI Z21.1O.3) is 93%. This efficiency goes up as inputdecreases, approaching99% efficiency at 10:1turndownratio. In this case, the seasonal performance oftheunit, becauseofpartload operation, is most likelyhigherthanthe steady-state, full-fire efficiency. Evaluatinglife-cyclecosts for this equipmentbasedonrated input efficiency will overestimatefuel consumption and costs.
Conversely, many types ofequipment operateless efficientlyunderpartload conditions. Ina reportthatevaluated seasonalperformanceofconventional steamboilers, theresults ofthree studies covering 13 boilers were analyzed. Thesteady-stateefficiencies ofthis equipmentranged from 70% to 85.4%, whilethe seasonal-efficiency estimates forthesame equipmentrangedfrom 56.6% to 73.7% (Hewett and Lobenstein 1992). Estimatingfuel consumptionbased onsteady-stateperformance is clearly inaccurate.
High-efficiency equipmentmay also requirehigherlevels ofmaintenance thanconventional equipment. This adds additional operatingcosts and, inthe absenceofsufficient**maint~nance,** 

### may add additional fuel costs as performance degrades. As anexample, consider aboilerwith aheatreclaimer added to theboilerstackto recoverenergy. Becauseofthe added complexitytothesystem, amore sophisticatedtuningprocess is requiredto achievetheexpectedpeakperformance. Properlytuned, the unitmay operateatfour percentagepoints abovetheconventional design. Withoutpropertuning,

. carbonmay sootup thetubebundles andboiler, possibly reducingperformancebelow thatofa standard model.

Performance measures inthis reportarebased oncurrenttestprocedures. Whenlifecyclecosts
areevaluated, itis importantto remember thelimitations ofthistypeofperformance information.


## 2.3 AvailabilityofCostandPerformanceData

Manufacturers, manufacturer representatives, and dealers arefrequently reluctantto releasecost information. Evenwhen apotentialproviderofinformationis identified, several contacts may be required beforethe information is released. Many manufacturers werecontacted in this datacollection effort, and repeated attempts were madeto ensuretheconfidentiality ofthe information. However, in

some cases, limited orno datawere available. InthecaseoftheHVAC equipment manufacturers, a further effortwill berequired to evaluateequipment costs. Becauseofthe sensitivity ofcostdata in this report, specific manufacturers arenot identified with regardto any costinformation. Also, equipmentparameters such as volume and inputwererounded to further disguisethedata.

2.4

### Whileperformancedata aremore readily available, sometypes ofperformance information are difficultto collect and may beofpoorquality. Though waterheaterperformance datafor most manufacturers arecollected inthe CaliforniaEnergy Commission (CEC) equipment database, thermalefficiency data aremissing for many fuel-fired waterheaters. Standby loss information is also missing for a significantfraction ofstorage-typewaterheaters. Some information ofthis type is availablefrom themanufacturers, butit is oftenonly ageneral estimateused in sales literature. TheCECdatabase does not includeunfired hotwater storagetanks,andno other sourceoftested standby loss performanceforthis equipment was identified.

TheCEC database also includes thermal-efficiency datafor warm airfurnaces and combustion efficiency datafor boilers. An additional sourceofboilerefficiency information is theHydronics Institute, whichpublishes ratings for Institute-certifiedequipment (Hydronics Institute 1994). A comparison ofdatafrom thetwo sourcesrevealed only afew discrepancies in theefficiency measures. Wherepossible, information from theCEC database was used,**~** 

### itprovides thebroadestcoverage. Other sources wereused to supplementthese data.


## 2.4 ModelDevelopment

With consistentmeasures ofcostandperformanceidentified, statistical models canbedeveloped relatingcosts to equipmentparameters. Whenthesemodels aredeveloped, many subjectivedecisions mustbemade abouttheform ofthemodels andthedatato be included inthe analysis. Whenresidual plots and otherstatistical measures ofgoodness offit areevaluated, itis possibleto eliminate some models from consideration. Inmany cases, however, there are still severalpossibleways in whichthe datacanbemodeled. Ifoutliers areeliminated, more accuratemodels canbedevelopedfor theremaining data. Whenthere is littlebasis for excluding anyparticulardata, however, otherthanthedifficulty in modeling it, an attempt is madeto revisethe model to accountforthesedata, eitherby including dummy variables orby regroupingthedatainto separatecategories.

Model validity can also bemeasured by theextentto which parameter estimates reflectthe expected relationships betweenequipment characteristics and cost. Because many oftheexplanatory variables used to characterizeequipment arecorrelated, it is oftendifficultto accountfor theeffectof each variableindependently. If

### thesecorrelations areunderstood, however, itis possibleto choosea setofvariablesthat, in general, reflectthemost importantparametersthat affectcost.

Models arereported along with theR-squared valuefor themodel. This is notmeantto imply that

ahigh R-squared value alone canbeused as ameasure ofthevalidityofthemodel. Infact, R-squared values are apoormeasure ofmodel validity, and comparisons ofR-squared values betweenmodels are onlyuseful incertainlimited circumstances. In orderto assess model validityothermethods wereused includingtheevaluationoft-statistics and standard errors, directevaluationofpredictedversus actual values, and theevaluationoftests for general model mispecification. In this way it is possibleto choose models which areboth statisticallyvalid, and which reflectthemost importantcharacteristics which affectcost.



### 2.5

### It is also extremely important to understand thebounds ofmodel validity. Any attempt to apply the model to equipment with characteristics outside ofthe bounds ofthe data set is invalid, and is likely to lead to poorestimates ofcost, especially for models involving power and logarithmic functions. These boundshave generallybeennoted when estimating equipment costs, and any attempt to produce additional cost estimates using these models should only be carried out after athorough examinationofthe relevant data set.

2.6

# 3.0 Definition ofEquipment Categories

EPAct standards only apply to certaincategories ofequipment, and these standards also vary betweenequipment subcategories. The following chapterdescribes the equipment categories found in EPAct.


## 3.1 WaterHeaters

In EPAct, commercial water-heating equipment is divided into six categories. These categories are presented in Table 3.1.

Theminimum input ratings for small-input fuel-fired storage waterheaters and fuel-fired instantaneous water heaters with greaterthan 10-gal storage are different for gas and oil models. Minimum oil inputs are given inparenthesis. Because no significantdifference was found in costs for largeinput, fuel-fired storage waterheaters and for fuel-fired instantaneous waterheaters withgreaterthan 10-gal storage volume, thesetwo categories are treated as one in this report and are referred to as fuelfired storage waterheaters. The remaining small-storage instantaneous units are referred to as tankless waterheaters. The characteristics ofthese equipment types are discussed further in Section 6. 1ofthis report.


## 3.2 PackagedBoilers

Commercial packagedboilers are defined in EPAct as units that are"

...shipped complete with heating equipment, mechanical draft equipment, and automatic controls; usually shipped in one or
more sections." This includes all equipment with rated capacity of300,000 Btu/hrormore and includes oil- and gas-firedunits and water and steamboilers. Separate standards exist for each fuel type, so they were examined separately.


## 3.3 Warm AirFurnaces

Awarm air furnace is defined in EPAct as "

...a self-contained oil- orgas-fired furnace designed to supply heated airthroughducts to spaces that require it and includes combination warm air furnace/ electric air conditioning units butdoes not include unit heaters and duct furnaces." Commercial equipment includes all units with rated capacity of225,000 Btu/hrormore. The ASHRAE analysis is based

on outdoor-type warm air furnaces. Because few data were available from manufacturers ofthis type ofequipment, baseline cost estimates were limited to warm (lir furnaces for indoor installation.

# 4.0 Description ofASHRAE CostAnalysis Methodology

Whenevaluatingthecostofcommercial equipment, ASHRAEreliedontwoprimary types of information: estimated contractorcostfor typical equipment and estimated incremental costforhighefficiency equipment. Contractorpricingfor thebaselineunits was developed by anengineering consultantwho contacted equipmentdistributors and askedthemfor equipmentcosts (by size) for up to four separatemodels and different sizes in each category. Theseestimates wereinflatedby 25%to accountfor contractormarkup and then averaged. Incremental costs abovethis baselinewereestimated based oninformation suppliedby manufacturers through associations such as GAMA and ARI. The manufacturers were asked in a surveyto estimatetheincremental cost, as apercentage, to produce equipment atvaryinglevels ofefficiency above an assumedbaseline. Theseincremental costpercentages werethenmultiplied by thebaselinecosts to develop equipment costs ateach ofthedesired efficiency levels. Thespecific details ofthecostcollectionexercisevaried for each ofthe major equipmentcategories and aredescribedbelow.

Costestimates forwaterheater equipmentweremade for 10 specific equipmenttypes and sizes. Only gas-firedequipment was considered inthis analysis.



### 4.1.1 BaselineCostEstimates

Baselinecostestimates arepresentedinTable4.1. Thesecosts arefor equipmentonly and include

anestimated 25% contractormarkup. Thecontractormarkup does notinclude labor coststo install theequipment. Thefirst four entries aregas-fired waterheaters with storagetanks. Based onthe ASHRAE waterheaterclassifications, thefirstthreemodels are storagewaterheaters, having an inputto-volumeratio ofless than4,000Btu/hr/gal. Thefourth model, based onthis ratio, is an instantaneous waterheater with greaterthan a 10-gal storagevolume. Thesecond setofequipment, labeled instantaneous waterheaters, areofcopperfinned-tube design. Theseunits haveno storagevolume otherthanthe quantity ofwaterheld in thetubing oftheequipment. Theseunits areessentially equivalentto hydronic-heating models, which areclassified as boilers. Finally, four sizes ofunfiredhot water storagetanks with insulationareincluded.



### 4.1.2 

## IncrementalCostEstimates

ASHRAE incremental costestimates arebased onmanufacturer responsesto acommercial water heater surveyconductedby GAMA. Thesurvey included threelevels ofthermal efficiency and two levels ofstandby efficiency, combined for atotal of20costlevels in five c;:ttegories ofequipment. Incremental costestimates weremade for only 14 levels. This information is presented in Table4.2.

## 4.2 Boilers

Baseline and incremental boilercostestimates weremadefor gas-fired units only.



### 4.2.1 BaselineCostEstimates

Baselinecosts for commercial packagedboilers weredeveloped from dealer quotes for both atmospheric and powerburnercast-iron and steel boilers. Information was collectedfor 10 size categories in therange of200

### kBtu/hrup to 4,000

### kBtu/hr. No information was collected oncopper orcopper/ nickel alloyboilers. Baselinecostinformation is presented inTables4.3 through 4.6.

Baselinecostestimates weredeveloped from these datafor four sizecategories: 300to 400 kBtu/hr, 400to 1,000

### kBtu/hr, 1,000to 2,500kBtu/hr, and 2,500to 4,000

### kBtu/hr. Only a small number ofthecosts listed in Tables 4.3 through4.6 are actually used. Thebaselinecostfor a300- to 

### 400-kBtu/hrhotwaterboilerwas estimated from the averagecostfor 

### 400-kBtu/hr atmospheric and powerburnercast-iron boilers. Similarly, the other sizecategories wereestimated from the average costs ofpower and atmospheric cast-ironboilers of800-, 1500-, and 

### 3,000-kBtu/hr sizes. Thesebaselinecosts were also used for the steamboiler analysis. Noneofthe steel boilercostdatawereused.

### 4.2.2 Incremental CostEstimates

Incremental cost estimates for high-efficiencypackagedboilers were suppliedby GAMA inthe form ofcurves ofcost versus efficiency for four size categories and two types ofboilers (steam and water). When analyzing life-cycle costs, ASHRAE assumed that baseline costs for hot water and steam boilers were roughly equivalent. To test this assumption, ASHRAE repeated life-cycle cost calculations with waterboilercost estimates increased by 10%to account for the slightly higher cost ofsteam boilers. Minimum life-cycle costs occurred at the same efficiency levels in both cases, so the assumption was deemed acceptable. Cost increments suppliedby GAMA are presented inTables 4.7 and 4.8.

# 5.0 Database Description

The equipment database in Appendix Aincludes six tables containing data onequipment with similar characteristics. Toprotectthe confidentiality ofthe cost information, all manufacturer-specific data were excluded. In addition, some cost information was deleted where equipment characteristics

were unique to aparticularmanufacturer. The remaining fields include descripters ofthe equipment and its characteristics that affect cost. The following sections describe the tables and the data that they contain.


## 5.1 CommonVariables

Fourcommon variables exist in eachtable ofthe database: record number (REC), cost type (CTYPE), list cost (LCOST), and estimated contractor cost (CCOST). List costs were providedby manufacturers, usually in the form ofpublished price sheets. Theseprice sheets represent either a retail listprice, which reflects retail pricing, or adistributor list price, which reflects distributorpricing. Neitherpricemeasures actual average retail ordistributor costs for the equipment. Instead they

areused as abasis for actual pricing, using some percentage discount ormarkup.

Thepublishedlistprices are included inthe equipment database, along with aprice-type descripter (CTYPE) (eitherretail [R] ordistributor [DD. This variablemeasures the approximate level ofthe list price. Another cost measure, CCOST, is used to representthe estimated contractorprice for the equipment. Wherepossible, CCOST was developed from list cost on the basis ofmanufacturer-supplied estimates ofthe wholesale discount from listprice. An additional 10% is added to estimated wholesale priceto account for dealermarkup. Some manufacturers offer adiscount offoflist price in a complicated fashion, making estimates ofthe wholesaleprice from the listprice difficult to calculate. When

no estimate ofthe listprice averagediscount was available, equipment dealers were contacted for contractorpricing. Average contractor costs were thenused to arrive at amultiplier to estimate contractor costs from the list price. Thevariable CCOST is used in the statistical analysis.

The values ofCCOST must also be modified to arrive at consumer cost. Commercial equipment is typically purchasedby acontractor who then charges some markup inadditionto the purchaseprice. This markup does not reflect labor costs for installing the equipmentbut instead covers overhead and profit. Contractormarkup may vary from less than 15

### %to more than 50

### %depending onthe characteristics ofthejob. Because aprecise method for evaluating average contractormarkups for commercial equipment does not exist, amidrange value of25

### %was used. This estimate is consistent with the contractormarkup that is used by ASHRAE. Costs developed from the statistical models presented below must be marked up by 25

### %to arrive at estimated consumer cost. The remaining database variables are describedbelow.

# 6.0 Estimate ofBaseline Consumer Costs

The consumer cost for commercial equipment is assumed to be the priCe paid by the consumer to a contractor for the equipment, not including installation. As discussedpreviously, estimating contractor markup for equipment is difficult because it varies as afunction ofthe customer, thejob size, and other factors. The baseline cost estimates that ASHRAE uses for equipment are developed from contractor cost estimates and an estimated 25

### %contractormarkup, not including labor. This estimate is consistent withreported values and is used in this report. The statistical models are reported in terms ofcontractor costs, and they are multiplied by 1.25 to arrive at estimated consumer cost.


## 6.1 WaterHeaters

Waterheater information was providedby 16 manufacturers. The database includes more than 1,500 individual waterheater records, which are divided into four categories: fuel-fired water heaters, fuel-fired tankless waterheaters, electric storage waterheaters, and unfired hot water storage tanks.



### 6.1.1 Fuel-Fired Storage Water Heaters

Fuel-fired storage waterheaters include three subcategories ofequipment: models with input ratings :::;; 155,000Btu/hr, models with input ratings> 155,000Btu/hr and an input-to-storage volume ratio less than4,000Btu/hr, and models with inputratings> 155,000Btu/hrand an input-to-storage volume ratio of4,000Btu/hr/gallonormore (labeled instantaneous in ASHRAE definitions). The lower inputbound for commercial models is also divided by fuel type: 105,000 Btu/hrfor oil-fired storagemodels and 75,000Btu/hr for gas-fired storagemodels. The lowerbound for instantaneous models is 210,000 Btu/hrfor oil-firedunits and 200,000 Btu/hrfor gas-fired units. These categories

are summarized in Table 6.1. This categorizationresults in the anomaly that a 160,000Btu/hrwater heater is classified as aresidential instantaneous water heater ifthe tankvolume is less than40 gal, or a commercial storage waterheater ifthe tankvolume is greaterthan orequal to 40 gal.
Despitethe complexity ofthis subcategorization, fuel-fired waterheaters with storage tanks are a fairly homogenous product. The designation ofinstantaneous waterheaters with greaterthan lO-gallon storage capacity attempts to capture the effect on standby losses ofincreased flue area athigh-input-tovolume ratios; however, units fallingjustbelow and above4,000 Btu/hr input-to-volume ratio are very similar. The separate designation ofunits above andbelow 155,000Btu/hr input also is directed at capturing differences in standby loss performance, as reflected in the standard.

### Thesetrends inperformance are verifiedby testing for differences in efficiency and standby losses betweenequipment subcategories.

Baselinecosts for these equipment categories were modeled as afunction oftheprimary characteristics ofthe equipment: input, warranty, tank construction, and efficiency. Information was provided by sevenmanufacturers ofstorage waterheaters totaling 295 units. The database contains information for 33 units with input of 155,000 Btu/hr

### 6.1.2 TanklessWaterHeaters

Low-volume instantaneous (tankless) waterheaters aredesignated inASHRAE 90.1-1989 as water heaters having an input-to-volumeratio of4,000Btu/gallhrormore, less than 10gal ofwater storage volume, and inputs>200,000Btulhrfor gas-firedunits and inputs greaterthan 210,000Btulhrfor oilfired units. Fivemanufacturers ofgas fired equipmentprovideddata. Severalmanufacturers ofoilfired boilers offeroptionsthatallow themtobeused as tankless waterheaters. However, because theseunits aremarketed as boilers, andbecausethe ASHRAE analysis does notconsideroil-fired equipmentin.this category, they werenotevaluated.
Inputratings for gas-firedequipmentrangefrom 225,000Btulhrto 21,000,000Btulhr. Performance datafor all 108 units wereavailablefrom theCECequipment database. Themajority ofthe units fall inthe combustion-efficiency range of80to 82%and areofcopperfinned-tube design. Highperformance copperfinned-tube units rangeto higherthan 88%efficiency. Onecompany manufactures asinglemodulating-input condensing model, which achieves efficienciesfrom 93%to 99%as inputranges from maXimum-rated capacityto a 10:1turndownratio. A completelineofhigh-input direct-contactmodels also exist, reaching99% efficiency. Inthis design, the coldinletwatercomes in directcontactwiththehotproducts ofcombustion, allowingvirtually all ofthethermal energyto be transferredto the water.
Usingtheefficiency atmaximum-rated inputfor themodulating condensingunit (93%), regression analysis using all ofthe datayields acostmodel ofinput and efficiency with averyhigh R-squared value (0.99). This may notbethebestmodel for estimating equipmentcosts for two reasons. First, theASHRAE analysis is limitedtoconsiderationofefficiencies from 80%to 86%, so includinghighefficiency models may diminish thevalidity atlowerefficiencies. Second, the direct-contactmodels

arevery large (1 to 21 millionBtulhr), so they do notrepresenttypical units inthe 80% to 86% efficiency range.

### Regression analysis ofCCOSTusing only units with 93%efficiency orless (96units) suggests models with input and efficiency as theexplanatoryvariables. Evaluatingresidual plotsrevealsthat a straightline model cannot accountfortheincremental costofhigh-efficiency equipment. Introducing a squaredterm onefficiency improves the R-squaredvaluefrom 0.81 to 0.90. Themodel below is used to estimatecost.

Whenevaluatingthelife-cyclecostforthis equipment, ASHRAEonlyused the400kBtulhrmodel. Thus, modeled costs are5.3% lowerthanASHRAE-developed costs.



### 6.1.3 ElectricStorage WaterHeaters

Electric storagewaterheaters makeup less than20%ofcommercial waterheatershipments accordingto datacoveringthefirst 7 months of 1994 (ApplianceManufacturer 1994,p. 15). Atthis time, ASHRAEhas notevaluatedthelife-cyclecostsfor baselineand high-efficiency electric storage waterheaters. Datafor electric storagewaterheaters are included inthedatabase, so amodel was developed for this equipment.

Thedatabasecontains about 1,000records for electric storageunitsproducedby ninecompanies, with tankvolumes rangingfrom 50to 1,000gallons and inputratings rangingfrom 13.5to 480kW. Whenthedatawereanalyzed, itwas found thatno simple model adequatelycharacterizedcosts inthe different sizeclasses. Instead, separatemodels weredeveloped for common sizeclasses; inthis case, 50, 80, and 120gal ofstoragevolume. Theseunits have avertical cylindrical configurationand are similarto residential electric waterheaters, buttheyhave aheavierconstruction. Costs were also found to be afunction ofthenumber ofthermostats and fuses used intheheater. Becausethis number typicallyvaries as afunction ofinput sizeclasses, theeffectcanbecapturedbyfurther segregatingthe



### 6.5

### heaters into three input categories: less than 20 kW, between 20 and 40 kW, and above 40 kW. These categories will be referredto in this report as class 1, 2, and 3, respectively (input alone did not capture these effects). The resulting models are presentedbelow.

### ifthe inputrating is above40 kW). R-squared values for the three models are 0.85, 0.87, and 0.89, respectively.



### 6.1.4 Unfired Hot Water Storage Tanks

Cost information for unfired hot water storagetanks was collected from eight manufacturers for a total of 143 units. Acursory examination ofthe data suggests that equipment costs are afunction of several factors, including the tank size; tankconstruction (standard or ASME); tank lining; and, for large-volume tanks, the tankorientation(vertical orhorizontal). Storagetanks also come with different warranty lengths, insulationtypes, andpressure ratings. Modeling cost as afunction ofthese parameters revealed four significantparameters: tank size, lining, orientation, and construction. Examinationofcostplots as afunction ofeach ofthese variables also revealed some nonstraight-line relationships inthe data. Avariety ofmodels involving logs ofthe dependent and independent variables were tested to account for these relationships. The resulting model (R-squared 0.93), based on 123 units, is givenbelow.
Ln(CCOST) = 0.823*Ln(VOL) 

## + 0.955*TANK 

## + 0.235*ORIENT 

## + .201*LIN 

## + 2.519 (0.0001) (0.0001) (0.0001) (0.0002) (0.0001)

where VOL is the volume in gallons, and TANK, ORIENT, and LIN are indicator variables (TANK = 

### 1for ASME, 0 for standard; ORIENT = 1for horizontal, 0for vertical; and LIN 

### = 1for glass, 0 for other).

In the ASHRAE analysis, cost information was gathered for four tank sizes: 120, 200, 500, and 1,000 gal. ASHRAE-developed costs are compared against the range ofmodeled costs, based on equipment characteristics (with the three dummy variables all set to either 0 or 1). This comparison is presented inTable 6.5.

Fortanks inthe 120- and 200-gal sizeranges, an optionfor horizontal orientationtypically does notexist. Glass-linedtanks are also byfar themostcommonly offered models. Table6.6compares ASHRAE costs withmodeled costs for vertical glass-lined storagetanks ofboth standard and ASME construction.

TheASHRAE-developedestimates fall betweenmodeled costestimates for glass-lined vertical standard and ASMEmodels. Adetailedunderstanding ofshipment quantities, bytype, for hot water storagetanks is necessaryto accurately assessthebaselinecosts for this equipment.

### the baselinecostestimate was derived from costs for iron boilers only and was the averageofestimated costs for**atmosp~eric-type** 

### and power-burner-typeboilers. ASHRAE considered only gas-fired boilers in the analysis.

Because energy efficiency regulations are insensitiveto boilertype, boiler costs in this study were modeled pooled into two categories based on fuel type. Explanatory variables for the boilertypes are then used to characterizecost differences betweenboilertypes. Thedatabase contains nearly 700 boilerrecords, ofwhich about570 are gas-fired and 115 areoil-fired.

Gas-fired boilers are modeled as afunction ofinput and efficiency, with dummy variables included to accountfor the costincrement for the following types ofmodels:

• steam boilers (STEAM 

# = 1; otherwise = 0)

• units with ventdampers (VENT= 1; otherwise =

• power-burner-typeunits (BURN= 1; otherwise = 0)

• line ofunits offered by one manufacturer for which the model otherwise consistently underestimates costs (OUT= 1; otherwise = 0).

## 6.3 WarmAirFurnaces

Spaceheating incommercial establishments is providedby several distincttypes ofequipment. Theseincludeductheaters, unitheaters, outdoorfurnaces, indoorfurnaces, and vertical airturnover (VATO) furnaces. EPActspecificallyexempts bothunitheaters and ductheatersfrom energy efficiencyregulations. VA TOfurnaces arealso excludedfrom EPActstandards, which coveronly furnaces that supplyheated airthroughducts. TheVATOoperates bypickingup cool air atfloor level and discharging it atthetop ofthefurnace. Theseunits areprimarily used in warehouses and other

### large storage areas. Oftheremaining two furnacetypes, commercial indoor warm air furnaces representarelatively small equipmentclass. In applications requiring indoorfurnaces, oneormoreunits may beused with capacities falling intheresidential equipmentrange (below 225,000Btu/hr). Rooftop combinationheating and air-conditioningunits makeup theremainder ofthemarket, accounting for about 14%ofcommercial and industrial energyusefor spaceheating (Hewettand Lobenstein 1992, p.41).

Costinformation was providedonlyby manufacturers ofindoor warm airfurnaces. Baseline efficiencies for this equipment are 80% for gas-firedunits and 81%for oil-firedunits. Thebestfit model, basedonall 57datapoints, gives cost as afunction offuel type and input. This model (R

# 7.0 Estimate ofHigh-Efficiency Incremental Cost

The statisticalmodels described in Chapter6.0areused to estimatethe incremental costs for highefficiency equipment. When model-developed incremental costestimates arecomparedto ASHRAEdeveloped costestimates, an understanding ofthedatafrom which themodels weredeveloped is critical. Themodels shouldnotbeusedto estimate incremental costs for equipmentthathas characteristicsthat are outsidetherange ofthedata setfrom whichthey weredeveloped.


## 7.1 Water Heaters

As withbaselinecosts, incremental costs for water-heatingequipment weredeveloped for four categories: fuel-fired storagewaterheaters, fuel-fired tankless waterheaters, electric storage water heaters, and unfiredhotwater storagetanks.



### 7.1.1 Fuel-FiredStorageWaterHeaters

Theincremental costassociated with low-inputhigh-efficiency storagewaterheaters canbeestimated from themodel described inSection6.1.1. This model was developedfrom datafor equipment up to 84%thermal efficiency and, therefore, cannotbeextendedto ranges withhigherefficiency. Two 100,000Btulhrhigh-efficiencycondensingmodels are offered,however, and byusingmanufacturer estimates oftheadded costfor thesemodels, acostincrementcanbeestimated to reachthecondensing regime (approximately 86% for gas fired equipment). Theresults arepresented in Table7.1 and are validonlyfor gas-fired equipment.

IntheASHRAE analysis, GAMA manufacturers estimated a 3

### efficiency level also includes areductionin standby losses. Whilethis reductioncanbeexpectedto result inadditional costs, it shouldbenotedthatthehigh-efficiency models that arethebasis for this estimate achieve standby loss ratings of 1%, well below the assumed standardlevel. Manufacturershave also indicated

### that, thoughhigh-efficiencyunits aretechnologically achievable, other issues such as premature equipment failurehavehindered theproductionofhigh-efficiency equipment, afact thatis mirrored in thelimited number ofsuch units onthemarket. An accurate assessment ofthe incremental costs for high-efficiencyequipment must accountfor any decline inotherperformance aspects, somethingthat is not donein analyses that assumethe samelevel ofnonefficiency-relatedperformance across all efficiency levels.

Thedataforunits with inputgreaterthan 155,000 Btu/hr

### did notreveal a statistically significant correlationbetweencostand efficiency, possiblybecauselittlevariationinefficiency existsforthis equipment. Theresults for units with inputless than 155,000Btulhrwereextrapolatedto this size range. This is consistentwith GAMA-suppliedcostincrement estimates, which arevery similar for the two categories ofequipment (Table4.2).



### 7.1.2 TanklessWaterHeaters

IntheGAMA survey ofcommercial waterheater manufacturers, incremental costestimates for low-volume instantaneous (tankless) waterheaters wereprovidedforthreelevels ofefficiency: 80% (baseline), 83%, and 86%. Theseestimates, along withestimates basedonthemodel presented in Section6.1.2, aregivenbelow inTable7.2.

The GAMA-developedestimates are almost identical to modeled incremental costs for the 400kBtulhr sizecategory and somewhathigherthanfor the 1,000kBtulhr sizecategory. Themodel also suggeststhat as rated inputincreases, the incremental costforhigh-efficiency equipment decreases. Thistrendis confirmedbylooking atequipment ofvarious efficiency levels producedby a singlemanufacturer. Thishas important implications for life-cyclecostestimates becauselarger equipment will also havegreaterfuel input, thus weightingtheimpactoffuel savings onlife- cycle cost. BecausetheASHRAE analysis is based on a400 kBtulhr model, which is relatively small, the life-cyclecostestimates for largerhigh-efficiency equipmentmay be inflated.

### 7.1.3 ElectricStorageWaterHeaters

No ASHRAE analysis has beenconducted onthe incremental costs for high-efficiency electric storagewaterheaters. Currentstandards apply onlyto standby losses, becausethermal efficiencies are
near 100%for this equipment. Theexisting standbyloss performance standard for commercial electric waterheaters is givenas afunction ofwater storagevolume, ingallons, and mustbeless than0.30 

### + 27/Vol. Thestandard is relatedto storagevolumeto accountfor therelationship betweenstoragevolume and the surfaceareafor tanks ofdifferent sizes. As volumeincreases, the surface-area-to-volume ratio for tanks with equal relativeproportions decreases. Fortanks with equal effective insulation, standby losses decreasewhenthevolume increases. This finding is reflected inthestandard.

Commercial electric storagewaterheaters inthe50- to 120-gal sizerange arecurrentlymanufactured almostexclusively with about 3 in. offoam insulation. This results in standbyloss performance that is nearthecurrentASHRAE standard, as canbeseenby examining standby loss dat?for these models listed inthedatabase. Thesemodels aremarketed as havingR-values of24or25. However, reaching suchhigh levels ofR-valuehas becomemoredifficultbecauseofanEnvironmental Protection Agencybanontheuseofcholoroflourocarbon (CFC)-based foaming agents, such as CFCR-11, with

anR-value ofabout 8per inch. Areplacement non-CFCfoaming agent, HCFC 14tb, is estimated to haveanR-valueofabout7.5/in., 

### effectivelyrequiring morethan3-1/8 in. offoam to reach R -24. Manufacturershavealso improved ontheeffectiveinsulationvalueby increasingthe amountof insulationontop ofthetank, decreasingthe surfaceareaofnonfoam insulationaroundthecontrols and heatingelements, and improvingtheinsulation (typicallyfiberglass) belowthetanks.

Incremental material costs for increasingthe insularionlevel to 4 in. canbecalculatedfrom tank dimensions and estimated costs for foam insulation ($1.50/1b 

### at 2.2Ib/fi3) and 20-gaugesteel-jacketing material ($0.32Ib at 1.5 Ib/ftZ). 

### Costincreases rangefrom $11 for a50-gal model to $18 for a 120-gal model. Based onamanufacturer markup ofabout 53.8% (gross marginof65%), 10% dealermarkup, and 25%contractormarkup, this would add $23 to $38 in additional material costs attheconsumer level. Thisequates to about a 2 %increase in costs for non-ASME surfacethermostat models.

Other**considerati~ns,** 

### such as theoverall sizeofthewaterheater, limitthepotential for increasing insulationlevels. Incremental energy savings also becomeextremely small as insulationlevels increase, partlybecauseenergy "leaks" aroundthepiping andfittings beginto outweighlosses through theinsulation. Greaterpotential for energy savings exists through substitutionofalternativewaterheatingmechanisms. Solarwaterheaters canpotentially savelargequantities ofenergy, butbecause theirperformancedepends onclimate, they areperhaps not suitablefor inclusionin anational standard. Fuel-fired waterheaters also reduceoverall energyconsumption whenelectricity generation losses areaccounted for. Heatpump waterheaters offerthepotential for largeenergy savings, but theirperformanceis highlydependentonambientconditions. Whilethebaselinecostmodel in Section 6.1.3 cannotbeextrapolatedto such low-inputranges, lightcommercial electric waterheaters with 120-gal storagecapacity and 4.5kW input (recovery of20gal/hrat90°F rise) typically cost about $1,000.

### 7.1.4 UniIredHotWaterStorageTanks

Little information is availableonthe standby loss performance ofunfiredhotwater storagetanks, and littlevariability exists inthelevel ofinsulation usedbydifferentmanufacturers on similar models. ReportedR-values typically rangefrom 13 to 16.7; however, thesemay onlyberough approximations basedontheestimatedperformance oftheparticulartypeofinsulationused. Theincremental costs associated with improving the standby lossperformance ofstoragetanks canbeestimated byexamining thetypes, quantities, and qualities ofinsulationusedwiththesetanks.

Several waterheatermanufacturers and insulationmanufacturers werecontacted onthethermal performanceofinsulation. Estimates ofthek-valuefor fiberglass waterheater insulationranged from 0.22to 0.3, with an average of0.27 (theunits onk are Btu-in.lhr/ftzIF). 

### Thistranslates to an R-value ofabout 3.7/in. 

### orR-14.S for4 in. ofinsulation. Thetheoretical heatloss for aplanarsurfaceinsulatedto this level, combined with atemperature differenceofSO"F, is 5.4.Btulhr*ff. Bycomparison, foam insulationhas k-values intherangeof0.11 to 0.14. Thefirstvalueis typical offoams such as CFCR-ll, and thelattervalueis typical ofnon-CFCfoams, such as HCFC 141b. Using anestimate oftheinsulatingcapabilityofnon-CFC foam gives anR-valueof7.5/in. 

### Thus, 2 in. offoam insulation, which is common onstoragetanks 

### inthe 120- to 200-gal size, yields anR-valueof 15 and a theoretical heatloss rateof5.3Btulhr*frZ.

Bothofthesevalues arebelow thecurrentstandardof6.5Btulhr*ftz, though actual losses for storagetanks insulatedto theselevels wouldbehigher. Heatloss from ahotwater storagetankwill differ from thisbasedonthe shapeofthetank, and thenumber and extentof"leaks" aroundthe insulation causedbyinletand outletpipes, and otherextrusions such as pressurereliefvalves. Freeconvectionof heatcanalso occurifheattraps arenotusedto controlmigrationofhotwater intothecool pipes. Despitetheseconsiderations, itis possibleto estimatethe incremental material costto increasethe quantity ofinsulation, basedontheestimated costofthe additional materials used. Costincrements, as
apercentageofbaselinecosts, arepresented inTable7.3.

Inthe GAMA commercial waterheater survey, manufacturers were askedto estimatethe incremental costto improvethethermal performanceofstoragetanks from amaximum of 13.6Btulhr*ft2 to 

### 6.5Btulhr*ff. This represents a52%increaseintheeffectiveinsulationvalue. Estimates arethat achieving 13.6Btulhr/ff

### would cost an additional 3%, and achieving 6.5 Btulhr/ft2 

### wouldcostan additional 10% overanassumed baseline. Theseestimates includenon-material-related costincreases and

canbeexpectedto behigherthanestimates based only onincremental material costs.

## 7.2 PackagedBoilers

The incremental costs for high-efficiency packaged boilers can be estimated from the model developed in Section 6.2. This model is based oncombustion efficiencies and is therefore not directly comparable to ASHRAE-developed incremental costestimates, which arebased onthermal efficiency. The results for an 800 kBtu/hr atmospheric cast-ironboiler arepresented in Table7.4.

Forthis sizeclass, incremental costestimates are similar for small incremental-efficiency improvements, butthe model results are much smallerfor larger incremental-efficiency improvements. However, the model should notbeused to extrapolatebeyond the range ofthedata set. Forcast-iron boilers, the range ofefficiencies is only 80% to 83.3%. Abovethis level, the model is only valid for copper- orcopper/nickel-typeboilers. Becauseefficiency standards are not equipment-type dependent, themodel canbeused to evaluatecost increments that are independentofequipmenttype. The model

can similarly beused to evaluate incremental costs for otherboiler size classes.


## 7.3 WarmAirFurnaces

TheASHRAE furnace analysis is based on outdoorfurnaces, acategory ofequipment manufactured primarily by large HVAC equipment companies. Becausethese manufacturers have declined to provide information, it

### is not possibleto evaluate the ASHRAE incremental costestimates at this time. Furthermore, there is littlevariability in efficiency between indoor-type warm air furnaces, so no incremental costestimates can be made for high-efficiency furnaces based onthe availabledata.

# 8.0 Conclusions

The purpose ofthis work is to support an evaluationofthe economic impact ofrevised commercial equipment standards. Adatabase ofcommercial equipment costs was created, and information from this database was used to develop models for baseline and high-efficiency equipment costs. In some cases, sufficient data were not available onhigh-efficiency equipment to accurately evaluate the incremental costs for this equipment. Wherepossible, othermeans were used to evaluate these costs. Also, information was not available for heatpumps, air conditioners, and outdoor warm air furnaces. Further data collectionwill be requiredto analyze costs for these types ofequipment.

The problems encountered in the cost data collectionefforthighlight the difficulty in making accurate assessments ofequipment costs. Not only is cost information considered sensitive and is thus difficult to collect, but the widevariability ofcost estimates also makes an accurate evaluation ofcosts extremely difficult. There is no single correct cost that canbe associated with agivenpiece ofequipment. However, by collecting alarge quantity ofdata, it is possible to 

### average out extreme values, identifying factors that affectcosts. Statisticaltools can also be employed to quantify the quality ofthe data and to reveal relationships betweenequipmentparameters and cost.

Some considerationofthe primary measure used in this study, listprice, is appropriate. List price figures, inthemselves, do not specifically measure the actual cost ofthe equipment at the wholesale, contractor, orconsumer level. Also, listprices may not accurately reflect the relationship ofprices betweenproducts manufactured by the same company. However, within a givenproduct line, it is assumed that listprices, to some extent, reflectthe manufactured cost associated with the size and features ofeachpiece ofequipment and that these costs will, onthe whole, bepassed on to the consumer. Through statistical analysis ofrelative costs as afunction ofequipmentparameters, models that relate cost to theseparameters canbe developed.

The results ofthis study show some ofthe strengths and weaknesses ofthis approach. Forbaseline cost estimates, the models provide auseful tool for evaluating the important equipment characteristics that affect cost. Fromthis understanding ofthe relationship betweenequipment characteristics and cost, an informed baseline cost estimate canbe made thatprecisely defines the attributes ofthe assumed baselinemodel. For incremental cost estimates, the models also provide amethod for estimating the incremental costs for high- efficiency equipment. In some cases, however, no significant relationship

was found betweenperformance and cost. Thiswas primarily due to the fact that for some equipment categories there was little range in efficiency for equipment currentlybeing marketed. These categories include electric storage waterheaters, unfired hot water storage tanks, and warm air furnaces for indoor installation.

Whenthe modeled baseline cost estimates are compared to ASHRAE-developed cost estimates, two important conclusions canbe drawn. First, ASHRAE baseline cost estimates do not contain sufficient information about the assumed characteristics ofthe equipment to accurately estimate costs. The model results highlight the wide range ofpossible costs based on equipment features that are typically offered

8.1

### with commercial equipment. Second, acomparison ofASHRAE and modeled costestimates revealed that a small number ofextremely high costestimates used by ASHRAEheavily impactedthe average costestimates. Thus, ASHRAEbaselinecostestimates weregenerally similarto orhigherthan modeled baselinecostestimates. Highbaselinecostestimates will tendto diminish theimportanceof energy savings onlife-cyclecosts forhigh-efficiency equipment, shiftingtheminimum life-cyclecost towards lower efficiency levels.

Two importantconclusions canalso bedrawnwhencomparingthemodeled incremental costestimates to ASHRAE-developed incremental costestimates. First, in some cases, ASHRAE estimates are not size specific. Themodeled results suggestthatequipment sizedoes affect incremental costs. This is clear intheincremental costestimates fortankless waterheaters, which differ significantlybetween sizeranges. Forthe sizerangeusedbyASHRAE, modeled and ASHRAE incremental costestimates

are almost identical. Forlarger-sized equipment, themodel predicts a smaller costincrement, highlightingtheimportance ofequipment sizeontheresults. Second, theASHRAE incremental costestimates areoftenequipment-type specific, which affects themagnitudeofincremental costs. Inthecase ofpackagedboilers, model results weredeveloped as afunction ofequipmenttype. Inthis way, incremental costs canbe independently estimatedfor theseequipmenttypes. This may beofvaluebecause EPAct standards arenotequipment-typedependent.

Several categories ofequipment werenotincluded inthe analysisbecauseoflackofdata. These include all categories ofheatpumps and airconditioners, warm airfurnaces for outdoorinstallation, and severaltypes ofoil-firedequipment. Additional datacollectionwill berequiredto evaluatebaseline and incremental costs for this equipment. Theresults ofthis study suggest, however, thatlistprice informationcanbeusedto estimatethesecosts, with otherinformationusedto supplement listprice datawherenecessary.
