1、Designation: E1664 95a (Reapproved 2018) 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.1.6 The values stated in SI units are to be regarded assta

The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in th

20、ificpurpose. E6313.1.1.1 DiscussionA facility may be within a building, awhole building, or a building with its site and surroundingenvironment; or it may be a construction that is not a building.The term encompasses both the physical object and its use.3.1.2 facility serviceabilitythe capability of
21、 a facility toperform the function(s) for which it is designed, used, orrequired to be used. E6313.1.2.1 DiscussionThe scope of this performance is of thefacility as a system, including its subsystems, components andmaterials and their interactions, such as acoustical,hydrothermal, air purity, and e
22、conomic; and of the relativeimportance of each performance requirement.3.1.3 offcea place, such as a room, suite, or building, inwhich business, clerical or professional activities areconducted. E6313.1.4 For standard definitions of additional terms applicableto this classification, see Terminology
23、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 that must be used for excess circulation,oversize
24、 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 preventsthe use of that space for furniture, equipment, ci
25、rculation, 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 furniturelayout for office functions, after deducting
26、the area of anybuilding elements or design features that prevent floor areafrom being so used, for example, columns, perimeterconvectors, and projections from walls; or a narrow spacebetween a column and a wall, which cannot be used forplacement of furniture or for people to walk; or an angle in awa
27、ll, or diagonal alignment of a wall, leaving a zone wherefurniture cannot 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 fixedair-conditioning equipment (see ASHRAE 62-1989).3.2
28、.6 primary circulationthe portion of a building that is apublic 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 oremergency exits or refuge areas.3.2.7 secondary c
29、irculation 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 all floor areas of a facilityassigned to, or available
30、 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 level of service-ability of a building or facility for
31、 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 is applicable despite differences such aslocation,
32、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 This classification can be used to estimate the follow
33、ing: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 planned.4.5 Use of this classification does not resu
34、lt 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 that arebuilding constructions, or parts thereof. (
35、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, use for regulatory purposes, nor for fire hazard a
36、ssessmentnor 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 instructions for using the table shown in Fig. 4are contained
