Significance and Use4.
44、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 practice can be used to classify areas for internalcost acc
45、ounting 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 the future, additional annexes are expected to be added to
46、this 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 AnnexA1 provides a procedure for measuring floor areaand fo
47、r 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. Where possible, also assess the extent ofvariation and state
48、as an estimate.6.3 If Practice E2619/E2619M 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.
