1、Designation: E 1836/E 1836M 091An American National StandardStandard Practice forBuilding Floor Area Measurements for Facility Management1This standard is issued under the fixed designation E 1836/E 1836M; the number immediately following the designation indicates theyear of original adoption or, in
2、 the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information and designation was corrected editorially in April 2009.1. Scope1.1 This
3、 practice provides a definitive procedure for mea-suring and classifying floor area in buildings 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 pract
4、ice is applicable to owned, rented, and leasedbuildings.1.4 Use Annex A1 to measure floor area in 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 a
5、nd building-related facilities.1.5 The practice inAnnexA1 is not intended for use in leasenegotiations 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 designati
6、on ANSI/BOMAZ65.11996 and commonly known as the ANSI-BOMA stan-dard.1.6 This practice is not intended 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
7、 ISO 9836Performance Standards in BuildingDefinition and Calcula-tion of Area and Space Indicators.1.8 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used
8、independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.9 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 saf
9、ety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

18、uilding or groupof buildings.73.2.1.1 DiscussionIn general, occupancy codes and regu-lations do not govern these areas, although there may be codesand regulations that relate to their specific uses.3.2.2 assignable area, nportion of the plannable area on afloor that can be assigned to occupant group
19、s or functions.3.2.3 building, ncontiguous and undivided shelter com-prising a partially or totally enclosed space, erected by meansof a planned process of forming and combining materials.73.2.4 dominant portion, nthe inside surface of the outsidewall, as defined in ANSI/BOMA Z65.11996.83.2.4.1 Disc
20、ussionANSI/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.3.2.5 excluded area, nportion of a floor within a buildingthat is not suitable for occupancy by people or equipme
21、nt.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 interior gross area calculations. Examplesof excluded areas include but are not limited to unfinished atticare
22、as, 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 renovation activity are not excluded areas.73.2.6 exterior gross area, nthe area of the floor measuredto the outside
23、 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, pilasters, buttresses, and so forth that extend beyondthe wall face are disregarded. The exterior gross area of abase
24、ment 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 the base building forthe general use of occupants, excluding the thickness of anyspecial surfacing materials a
25、pplied 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, nbase building element thatis located inside a building, not on an outer wall, and thatprevents the use of the

31、ide the dominant portion ofa building on the outer wall and that prevents the use of thefloor area for furniture, equipment, circulation, or other occu-pant function.93.2.18 plannable gross area, nportion of a floor that istotally enclosed within the interior face of perimeter encroach-ments at the
32、floor plane and where there are no perimeterencroachments enclosed at the inside finished surface of theexterior walls.103.2.19 polygon, nclosed plane figure made up of severalline segments that are joined together.123.2.20 primary circulation area, nminimum path on afloor for access to egress stair
33、s, elevator lobbies, toilet rooms,refuge areas, building lobbies, and entrances.93.2.21 restricted area, nportion of floor area that wouldnormally be available for use by an occupant, but the occupantis limited from using the area, either by regulatory authority orfrom a governing document.93.2.22 r
34、estricted 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 occupancy.3.2.22.1 DiscussionRestricted headroom is primarily in-tended to exclude large areas such as low attics
35、and crawl-spaces from being defined as “floors.” It also establishes, in asloped ceiling attic or sloped exterior wall, where the effective7Copyright is shared with BOMA International.8In the 1996 edition, which is copyright by BOMA, the dominant portion isdefined as the inside face of the portion o
36、f 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. Note that the reader is cautioned that thedominan

Examples are: (1) small areas betweenfurniture panels and columns where furniture does not fit; and(2) area set aside to install future workstation or otherfunctions.3.2.26 usable area, nportions of a building
43、 that can beclassified as tenant area or amenity area.143.2.27 void area, nabsence of a floor inside the dominantportion where a floor might otherwise be expected or mea-sured, that is typically in the plane of the upper floors ofmulti-story atria or lobbies, light wells, auditoria or the areaadjace

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 programming andforecasting of space requirements.4.3 This pr
45、actice 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 functional types of building is contained in AnnexA1.NOTE 1In t
46、he 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 different countries.6. Measurement Procedure and Report6.1 An
47、nexA1 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 Annex A1, note any exceptions to theprescribed method. Wher
48、e possible, also assess the extent ofvariation and state as an estimate.6.3 If Practice E 2619/E 2619M is also used, findings fromthat practice may be included in the report of building floorarea measurement, but the area of building loss features shallbe clearly identified.7.
