1、Designation: E 1836 08An American National StandardStandard Practice forBuilding Floor Area Measurements for Facility Management1This standard is issued under the fixed designation E 1836; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi

2、sion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice provides a definitive procedure for mea-suring and classifying floor area in buildings

3、 for use in facilitymanagement, specifying occupant requirements, space plan-ning, and for strategic facility planning.1.2 This practice specifies the sequence in which to measurefloor area.1.3 This practice is applicable to owned, rented, and leasedbuildings.1.4 Use Annex A1 to measure floor area i

4、n office facilities.The measurement practice in Annex A1 may also be suitablefor use in other functional types of building which includeoffices, such as research, laboratory, or manufacturing build-ings and building-related facilities.1.5 The practice inAnnexA1 is not intended for use in leasenegoti

5、ations with owners of commercial office buildings orrelated properties. For that purpose, refer to the AmericanNational Standard published by the American National Stan-dards Institute under the designation ANSI/BOMAZ65.11996 and commonly known as the ANSI-BOMA stan-dard.1.6 This practice is not int

6、ended for and not suitable for usefor regulatory purposes, fire hazard assessment, and fire riskassessment.1.7 This practice was developed for use within NorthAmerica and includes some rules comparable to ISO 9836Performance Standards in BuildingDefinition and Calcula-tion of Area and Space Indicato

7、rs.1.8 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. Reference

18、3.2.4 dominant portion, nthe inside surface of the outsidewall, as defined in ANSI/BOMA Z65.11996.83.2.4.1 DiscussionANSI/BOMA Z65.11996 specifieswhen to consider the inside surface of the window glass as thedominant portion to measure to, and when to measure to someother part of the outside wall.3.

19、2.5 excluded area, nportion of a floor within a buildingthat is not suitable for occupancy by people or equipment.73.2.5.1 DiscussionWhile excluded areas may meet thecriteria of adequate clear headroom there is owner/landlorddocumentation which indicates that these areas are to beexcluded from floor

20、 interior gross area calculations. Examplesof excluded areas include but are not limited to unfinished atticareas, attic areas with obstructed access, damp or floodedbasements, and confined areas requiring permits for entry.Areas temporarily unusable due to flood, fire damage, con-struction or renov

21、ation activity are not excluded areas.73.2.6 exterior gross area, nthe area of the floor measuredto the outside face of the walls that enclose the floor(s) of thebuilding.3.2.6.1 DiscussionAreas which are not enclosed, such aspatios and balconies, are not part of exterior gross area.Cornices, pilast

22、ers, buttresses, and so forth that extend beyondthe wall face are disregarded. The exterior gross area of abasement space includes the area measured to the outside faceof basement or foundation walls.3.2.7 finished surface, ninside face of a wall, window,ceiling, or floor that is provided as part of

23、 the base building forthe general use of occupants, excluding the thickness of anyspecial surfacing materials applied to meet the particular needsof specific occupants.93.2.8 floor area, narea in the horizontal plane of thebottom level of a story or stories in a building.3.2.9 interior encroachment,

24、 nbase building element thatis located inside a building, not on an outer wall, and thatprevents the use of the floor area for furniture, equipment,circulation, or other occupant function.93.2.10 interior gross area, nportion of the floor(s) that istotally enclosed within the dominant portion.93.2.1

32、he occupantis limited from using the area, either by regulatory authority orfrom a governing document.93.2.22 restricted headroom, nlarge portion of a floor thatdoes not have sufficient clear, unobstructed headroom toconform to local building codes or that has headroom less thanthat required for occ

33、upancy.3.2.22.1 DiscussionRestricted headroom is primarily in-tended to exclude large areas such as low attics and crawl-spaces from being defined as “floors.” It also establishes, in asloped ceiling attic or sloped exterior wall, where the effectiveouter wall is located. Restricted headroom does no

34、t apply toreduced or no headroom conditions (that is, walls, columns,stairs, door headers, limited piping, railings, alcoves, and soforth) typically found on a floor, unless they are part of anoverall restricted headroom condition.8In the 1996 edition, which is copyright by BOMA, the dominant portio

35、n isdefined as the inside face of the portion of the wall which is window glass where itis more than 50 % of the vertical distance from finished floor to finished ceiling, andelsewhere as the inside face of the outside wall, or of a pilaster or column attachedto the outside wall where they occur.

40、area that cannot be classified as either assignable area, orrestricted area, or occupant void, or interior encroachment, orsecondary circulation. Examples are: (1) small areas betweenfurniture panels and columns where furniture does not fit; and(2) area set aside to install future workstation or oth

Significance and Use4.1 This practice can be used to facilitate comparison ofareas that have been measured but it does not specify whatmeasurements must be conducted.4.2 This practice can be used in space progr

43、amming andforecasting of space requirements.4.3 This practice can be used to classify areas for internalcost accounting purposes.4.4 This practice can be used to compare space use betweenorganizations.5. Basis of Practice5.1 The basis for classification of floor area measurementsfor certain function

44、al types of building is contained in AnnexA1.NOTE 1In the future, additional annexes are expected to be added tothis practice to contain the classifications for floor area measurements inother functional types of building and to compare measurements of floorarea for different purposes or from differ

45、ent countries.6. Measurement Procedure and Report6.1 AnnexA1 provides a procedure for measuring floor areaand for reporting such measurements for certain functionaltypes of building for those purposes stated in Section 1.6.2 When reporting floor area, measured in accordance withthe procedure in Anne

46、x A1, note any exceptions to theprescribed method. Where possible, also assess the extent ofvariation and state as an estimate.7.
