21、and may contain material that has not been subject topublic review or a consensus process. Unresolved objec-tors on informative material are not offered the right toappeal at ASHRAE or ANSI.)FOREWORDThere are many commercial entities that are rating buildingsutilizing a number of different building

22、rating systems yield-ing varying results. ASHRAE Standard 214 is a noncommer-cial consensus standard that provides uniformity in thebuilding energy labeling and disclosure process and can beused in international, national, and regional legislation, pol-icy making, and regulation activities.1. PURPOS

23、E1.1 The purpose of this document is to provide a standard-ized approach and methodology for determining and express-ing building energy performance in a rating program.1.2 The purpose of this document is to standardize the con-tent of the label associated with the energy component of arating progra

24、m and to establish minimum requirements forrating program documentation.2. SCOPE2.1 This standard applies to the following:a. New and existing buildings.b. The building site or campus on which the buildings arelocated and all accessory and appurtenant structures,energy-using systems, and equipment l

25、ocated on the build-ing site.2.2 This standard establishes requirements for the following:a. Disclosure of building energy use via a rating and support-ing summary documentation.b. Modeling of buildings and building sites to estimate orpredict building energy use for an asset rating.c. Determining e

26、nergy use, with metered data, of buildingsand building sites to establish an operational rating.d. Acceptable credentialing criteria for individuals applyingthis standard and reporting building energy use.e. Format and content of the rating disclosure, the label, andsupporting documentation.2.3 This

27、 standard is intended to be used with one or multipleenergy performance metrics.2.4 This standard applies to only the energy component of arating program. 3. DEFINITIONSauthority having jurisdiction (AHJ): the agency or agentresponsible for enforcing this standard.building use type: the classificati

28、on of a building based on itsintended use as determined by the use and occupancy classifi-cation for the building that has been established by the AHJ. certificate: a document issued by the rating program.label: a symbol or other identifying mark of a third party,independent of the building owner, t

29、hat is attached to thebuilding. The label signifies that the building complies withthe requirements of the rating program. normalization parameter: a factor or parameter that allowsfor the normalization of energy use by the factor or parameter(e.g., Btu/studentyr or kWh/widgetyr) chosen to allow for

30、expression of energy performance.verification: the process by which specific documents, com-ponents, equipment, assemblies, systems, and interfacesamong systems are confirmed to comply with the criteriadescribed in the rating program. Informative Note: See http:/www.ashrae.org/terminologyfor additio

31、nal terms and definitions.4. SCOPING OF THE PROGRAM4.1 Parameters. The rating program shalla. define the parameters and methodology used to predict ormeasure energy use in a building, b. define the inputs required and the calculations and proce-dure used to determine a score for each rated building,

32、 andc. provide the methodology for comparison of a rated build-ing to similar buildings in the same climate zones and thedetermination of a comparative score.4.2 Type and Boundaries of Building. The standard shallindicate which building use types are covered. The rating pro-gram shall provide docume

33、ntation for how to determine thelimits or boundary of the rated building.4.3 Location. The rating program shall indicate the applica-ble geographic, municipal, state, or international area, loca-tion, or country.4.4 Type of Rating. Each rating program shall identify theapplicable types of rating (as

34、set, operational, or other).5. BUILDING5.1 General. The energy performance rating program seek-ing compliance with the requirements of this standard shallinclude one or more of the following buildings and all of theiroperating systems: a. Proposed buildingsb. Newly constructed buildingsc. Existing i

35、n-use buildingsd. Existing buildings following alteratione. An addition to an existing building The aspects subjected to the rating comprise any or allenclosed spaces and operating systems that contribute to orinfluence energy performance and are associated with thebuildings requirements.

The rating pro-gram shalla. disclose how it cat

37、egorizes building use types and condi-tioned spaces and b. define how it applies to different building use types, mixed-use buildings, partial buildings, or groups of buildings. These categories and definitions shall be documented andpublicly available.5.3 Building Characteristics Associated with En

38、ergy Per-formance. All of the following building characteristics shallbe included in a whole-building rating program, and one ormore characteristic shall be included in a rating program thatis not for whole buildings:a. Local climate Informative Note: Examples include site elevation andhourly values

39、 for climatic data, including air temperature (dryand wet-bulb), solar radiation, wind speed and direction, andrelative humidity.b. Building use typeInformative Note: Examples include occupant activitylevels and densities, internal gains, and associated schedules.c. Building envelopeInformative Note

40、: Examples include U-factors, air tight-ness, and window-wall ratio.d. Mechanical systemsInformative Note: Examples include space heating, cool-ing and ventilation, service water heating, pumps, fans, andother auxiliary equipment.e. Electrical systemsInformative Note: Examples include lighting, powe

41、r dis-tribution, and plug loads.f. Process loadsg. Energy-producing systemsA rating program that is not for whole buildings shall dis-close how excluded building characteristics are addressed.6. TYPE OF RATING6.1 General a. The type of rating being used depends on parameters andrestrictions listed i

42、n this section; this applies to all ratingtypes listed in this section. b. The rating shall be based on energy performance. Informative Note: Examples of energy performance met-rics include but are not limited to site, source, carbon, and cost. c. The rating program shall be developed and revisedthr

43、ough an open process that considers input from materi-ally affected parties. d. SI and I-P units shall be used in calculations, as applicable.e. The rating is applicable to residential, industrial, or com-mercial building sectors. Different methodologies shall bepermitted to apply to each sector. f.

44、 The rating shall be permitted to be based on the wholebuilding or defined boundary portions of the building, aslong as the energy use is measurable by approved meansand methods that are the subject of the energy analysis.
