Designation:E 1464 92(Reapproved 1999)An American National StandardStandard Guide forDeveloping Energy Monitoring Protocols for Commercialand Institutional Buildings or Facilities1This standard is issued under the fixed designation E 1464;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide describes a methodological approach todeveloping protocols for collecting empirical building orfacility energy performance data.1.2 The methodological approach covered in this guide isappropriate for commercial and institutional buildings orfacilities,and with some adaptations,the approach can also beused for larger multifamily buildings or small industrial build-ings or facilities.1.3 This guide does not specify a complete project orexperimental design,the hardware or software needed for datacollection and data management,or the data analysis tech-niques to be used.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:E 631 Terminology of Building Constructions23.Terminology3.1 Definitions:Terms related to buildings and facilities inthis guide are defined in Terminology E 631.3.2 Definitions of Terms Specific to This Standard:3.2.1 buildinggenerally used in this guide to refer toeither a building or a facility.4.Significance and Use4.1 The collection of empirical data to determine buildingenergy performance is an important but complex and costlyactivity.Careful development of energy monitoring projectscan make a crucial difference in the value of project resultsrelative to the expense.4.2 Increasing the widespread understanding of how energyis used and the types of services it provides in commercial,institutional,and related(light industrial,large multifamily,and mixed commercial/residential)buildings has proved to bedifficult.This difficulty arises from the following variables:thecomplexity of buildings as energy systems;the diversity ofsizes,uses,schedules,and types of buildings;the changes inuses of buildings;and the mixture of uses within individualbuildings.These factors make building energy performanceand energy(and dollar)savings from energy improvementsdifficult to categorize and compare.4.3 The audience for this guide is diverse,including energysuppliers such as utilities,building owners and managers,building occupants,designers,public and private researchorganizations,equipment manufacturers,and public regulators.4.4 The user of this guide must be familiar with thefundamental techniques of engineering project managementand energy performance data collection,data management,anddata analysis.See Refs(1-4)3for a discussion of techniquesrelated to the collection and analysis of energy performancedata.5.Procedure5.1 Because initial goals and objectives often lead to exces-sive costs for field data collection,an iterative approach toproject development is usually necessary.Once the goals andobjectives are defined,costs for completing the project can beestimated.If the costs are too high,the goals and objectives areredefined(next iteration)to attempt to achieve more realisticcosts,and further iterations are conducted as necessary.5.2 Project Development Activities:5.2.1 Identify project goals,objectives,questions to beanswered by the project,and constraints such as the availablebudget.This activity should always be conducted early inproject development.5.2.2 Specify the minimum data products and the desiredproject output.The data needed to answer the project questionsor meet specific objectives must be identified.The data1This guide is under the jurisdiction of ASTM Committee E-6 on Performanceof Buildings and is the direct responsibility of Subcommittee E6.25 on OverallPerformance of Buildings.Approved April 15,1992.Published June 1992.2Annual Book of ASTM Standards,Vol 04.11.3The boldface numbers in parentheses refer to the list of references at the end ofthis guide.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.manipulations or calculations necessary to provide the desiredresults should be identified.If possible,desired formats for thepresentation of data results should be developed.The nature ofthe minimum expected final output should be defined.5.2.3 Choose an experimental design that is appropriate forthe project to be conducted(1-3).The design is influenced bychoices between the number of buildings to be
