1、Designation: E1664 95a (Reapproved 2012)An American National StandardStandard Classification forServiceability of an Office Facility for Layout and BuildingFactors1, 2This standard is issued under the fixed designation E1664; the number immediately following the designation indicates the year oforig
2、inal adoption or, in the case of revision, 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 classification covers pairs of scales for classifyingan as
3、pect of the serviceability of an office facility, that is, thecapability of an office facility to meet certain possible require-ments for layout and building factors.1.2 Within that aspect of serviceability, each pair of scales,shown in Figs. 1-3, are for classifying one topic of serviceabil-ity. Ea
4、ch paragraph in an Occupant Requirement Scale (seeFigs. 1-3) summarizes one level of serviceability on that topic,which occupants might require. The matching entry in theFacility Rating Scale (see Figs. 1-3) is a translation of therequirement into a description of certain features of a facilitywhich
5、, taken in combination, indicate that the facility is likelyto meet that level of required serviceability.1.3 The entries in the Facility Rating Scale (see Figs. 1-3)are indicative and not comprehensive. They are for quickscanning to estimate approximately, quickly, and economically,how well an offi
6、ce facility is likely to meet the needs of one oranother type of occupant group over time. The entries are notfor measuring, knowing, or evaluating how an office facility isperforming.1.4 This classification can be used to estimate the level ofserviceability of an existing facility. It can also be u
7、sed toestimate the serviceability of a facility that has been plannedbut not yet built, such as one for which single-line drawingsand outline specifications have been prepared.1.5 This classification indicates what would cause a facilityto be rated at a certain level of serviceability but does not s
8、tatehow to conduct a serviceability rating nor how to assign aserviceability score. That information is found in PracticeE1334. The scales in this classification are complimentary toand compatible with Practice E1334. Each requires the other.2. Referenced Documents2.1 ASTM Standards:3E631 Terminolog

E6313.1.4 For standard definitions of additional terms
18、applicableto this classification, see Terminology E631.3.2 Definitions of Terms Specific to This Standard:3.2.1 building loss factorin a facility, expressed as apercentage of a facilitys usable floor area, the space noteffective for planning because of building design. It is the floorarea percentage
19、 that must be used for excess circulation,oversize footprints, or “dead space,” because of floorplateconfiguration.3.2.2 building projectiona pilaster, convector, baseboardheating unit, radiator, or other building element located in theinterior of a building adjacent to a building wall that prevents
20、the use of that space for furniture, equipment, circulation, orother functions.3.2.3 floorplatean entire floor of a building, thought of asa solid plane with specific shape and dimensions.3.2.4 occupiable areathat portion of usable area that isactually available for efficient space planning and furn
21、iturelayout for office functions, after deducting the area of anybuilding elements or design features that prevent floor areafrom being so used, for example, columns, perimeter convec-tors, and projections from walls; or a narrow space between acolumn and a wall, which cannot be used for placement o
22、ffurniture or for people to walk; or an angle in a wall, ordiagonal alignment of a wall, leaving a zone where furniturecannot be placed.3.2.5 occupied zonethe region within an occupied spacebetween planes 3 and 72 in. (75 and 1800 mm) above the floorand more than 2 ft (600 mm) from the walls or fixe
23、dair-conditioning equipment (see ASHRAE 62-1989).3.2.6 primary circulationthe portion of a building that isa public corridor, lobby, or the common-use portion of the basefloor of an atrium; or is required for access by all occupants ona floor to stairs, elevators, toilet rooms, or building entrances
24、 oremergency exits or refuge areas.3.2.7 secondary circulation areathe portion of a buildingrequired for access to some subdivision of space whetherbounded by walls or not, that does not serve all occupants ona floor, and that is not defined as primary circulation area.3.2.8 usable areathe sum of al
25、l floor areas of a facilityassigned to, or available for assignment to, occupant groups,including interior walls, building columns and projections, andsecondary circulation.4. Significance and Use4.1 Each Facility Rating Scale (see Figs. 1-3) in thisclassification provides a means to estimate the le
26、vel of service-ability of a building or facility for one topic of serviceabilityand to compare that level against the level of any other buildingor facility.4.2 This classification can be used for comparing how welldifferent buildings or facilities meet a particular requirementfor serviceability. It
27、 is applicable despite differences such aslocation, structure, mechanical systems, age, and buildingshape.4.3 This classification can be used to estimate the amount ofvariance of serviceability from target or from requirement, fora single office facility or within a group of office facilities.4.4 Th
28、is classification can be used to estimate the following:4.4.1 Serviceability of an existing facility for uses otherthan its present use.4.4.2 Serviceability (potential) of a facility that has beenplanned but not yet built.4.4.3 Serviceability (potential) of a facility for which re-modeling has been
29、planned.4.5 Use of this classification does not result in buildingevaluation or diagnosis. Building evaluation or diagnosisgenerally requires a special expertise in building engineering ortechnology and the use of instruments, tools, or measurements.4.6 This classification applies only to facilities
30、 that arebuilding constructions, or parts thereof. (While this classifica-tion may be useful in rating the serviceability of facilities thatare not building constructions, such facilities are outside thescope of this classification.)4.7 This classification is not intended for, and is not suitablefor
31、, use for regulatory purposes, nor for fire hazard assessmentnor for fire risk assessment.5. Basis of Classification5.1 The scales in Figs. 1-3 contain the basis for classifica-tion.5.2 Instructions for the use of this classification are con-tained in Practices E1334 and E1679.5.3 Detailed instructi
