Scope1.1 What This Guide DoesThis guide helps designers,builders, home owners, and other stakeholders to identify andevaluate benefits and costs in order to make efficient choicesbetween two or more traditional alternatives and betweentrad

8、itional alternatives and new-technology products, systems,materials, and designs. It directs the users to ASTMclassifications, practices, adjuncts, and computer programs thatimplement the appropriate economic method to evaluate thesebenefits and costs in making technology choices. The focus,however,

9、 is on a nine-step process for using two ASTMpracticeslife-cycle costing (LCC), E917, and the analyticalhierarchy process (AHP), E1765to measure and evaluate theeconomic and overall performance of investments in single-family attached and detached dwellings. This guide containsthree appendixes. The

10、first two are designed to help usersidentify and evaluate benefits and costs. Appendix X1 containsa classification of benefits and a methodology for estimatingthese benefits. Appendix X2 contains a classification of costsand a methodology for estimating these costs. Appendix X3illustrates how to eva

13、 guide for du-rability.1.2 Purpose of This GuideThe purpose of this guide is tohelp users make cost-effective choices between traditionalalternatives and new technologies permitted under perfor-mance standards. This guide (1) explains how the lack ofeconomic information discourages the introduction

14、of newtechnologies; (2) helps decision makers to identify and classifythe key types of benefits and costs associated with both newtechnologies and traditional alternatives; (3) shows how toselect alternatives that meet the performance standards, butcost less than traditional alternatives; and (4) sh

16、rmance of traditionalalternatives and new technologies permitted under perfor-mance standards for single-family attached and detacheddwellings. Use this economic analysis guide in evaluatingalternatives permitted under any of the other 15 performanceattributes, either singly or in combination. The o

17、bjective ofeconomic analysis in this guide is to identify cost-effectivechoices among traditional alternatives and new technologiespermitted under performance standards. The other 15 perfor-mance attributes define the scope of the economic analysis.That is, cost-effectiveness derives from better eco

18、nomic valuewhile providing comparable or better technical performancefor each attributes O-C-E-C performance statements.Consequently, to evaluate the economic performance of alter-native residential designs, materials, products, components,subsystems, or systems permitted under performancestandards,

19、 the user of this guide must first select one or moreattributes, use the O-C-E-C framework to develop and presentthe corresponding performance statements, and identify thealternatives to be evaluated.

31、Significance and Use4.1 Why This Guide Is NeededThe lack of information oneconomic consequences discourages the introduction of newtechnologies permitted under performance standards. The eco-nomic information needs are further complicated becausedecisions to adopt or accept a new technology are made

32、 bydifferent types of stakeholders (for example, building materialsmanufacturers, home builders, and home owners). Thus, thetype of economic information treated in this guide and theassociated standard classifications, practices, adjuncts, andcomputer programs covers the information needs of the ent

33、iregroup of key stakeholders.4.2 Use of This Guide by Specificers and ProvidersTomake efficient choices, decision makers require factual infor-mation on both how a particular alternative addresses therelevant performance statements and how much it costs. TheO-C-E-C framework enables the specifier to

34、 develop theperformance statements that satisfy one or more user needs andincorporate them into a request for proposals. Providers re-spond to the request for proposals by offering designs,materials, products, components, subsystems, or systems foracceptance. Because cost is one aspect of each provi

35、dersresponse, the specifier has an opportunity to request informa-tion from the provider that may be used in evaluating economicperformance. This guide is intended as a resource from whichthe specifier compiles lists of information to be collected aspart of each providers response to the request for

36、 proposals. Itis also intended for use by providers in preparing their responseto the specifier. The generic types of information that thespecifier may request from the provider in their response to therequest for proposals are described in Appendix X1 for benefitsand Appendix X2 for costs. A detail

37、ed example based on thedurability attribute is given in Appendix X3.4.3 Use of Economic Tools for Evaluating NewTechnologiesHaving a package of economic tools (methodsand software) that helps decision makers identify and evaluatebenefits and costs when choosing between traditional alterna-tives and

38、new-technology products, systems, materials, anddesigns will accelerate the introduction and acceptance of newtechnologies which are cost effective.4.4 Use of ASTM Standards on Building EconomicsStandard practices for using life-cycle costing (LCC), E917,and the analytical hierarchy process (AHP), E

39、1765, to measurethe economic and overall performance of investments inbuildings and building systems have been published byASTM.Two computer programs3,4that produce economic measuresconsistent with these practices are available. The BuildingMaintenance, Repair, and Replacement Database Program andth

40、e Discount Factor Tables have been published (Adjuncts toE917) by ASTM to facilitate computing measures of perfor-mance for the LCC practice. The economic tools described inthis guide apply to the evaluation of all the building elementsas described in the series of performance standard guides aswell

41、 as in the UNIFORMAT II elemental Classification E1557.4.5 Features and Limitations of Economic ToolsFor adescription of how to calculate the economic measures, how tointerpret them, and their limitations, see Practice E917 for theLCC method and Practice E1765 for the AHP method.5.

How to Use This Guide6.1

45、 Select the Performance Attribute(s)Select one or moreof the other fifteen ASTM performance attributes. Use theO-C-E-C framework to develop and present the correspondingperformance statements for the performance attribute(s) ofinterest. Use information received from providers in responseto the speci

46、fiers request for proposals, or by other means, as asource of data to support the economic analysis.6.2 Select the Building Alternatives to be EvaluatedSelectat least two building alternatives for evaluation. Designate onealternative as the base case. It is generally easiest to use atraditional alte

47、rnative (that is, design, system, or material) asthe base case. Select one or more new-technology or conven-tional alternatives to be evaluated vis-vis the base case.Select only alternatives which are acceptable substitutes inperformance for the base-case alternative.6.3 Select the Economic Method:6

48、.3.1 Life-Cycle Costing (Practice E917)6.3.1.1 The life-cycle cost (LCC) method provides a frame-work for comparing life-cycle costs of alternative buildingdesigns, systems, or materials that satisfy the same perfor-mance statements.6.3.1.2 The LCC method measures, in present-value orannual-value te
