1、Designation: E 2320 04An American National StandardStandard Classification forServiceability of an Office Facility for Thermal Environmentand Indoor Air Conditions1, 2This standard is issued under the fixed designation E 2320; the number immediately following the designation indicates the year ofori
2、ginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification contains pairs of scales for classify-ing
3、 an aspect of the serviceability of an office facility, that is,the capability of an office facility to meet certain possiblerequirements for suitable thermal environment and indoor airconditions.1.2 Within this aspect of serviceability, each pair of scales,shown in Figs. 1-53, is for classifying on
4、e topic of serviceabil-ity. Each paragraph in an Occupant Requirement Scale (seeFigs. 1-5) summarizes one level of requirement for service-ability on that topic, which occupants might require. Thematching paragraph in the Facility Rating Scale (see Figs. 1-5)is a translation of the requirement into
5、a description of certainfeatures of a facility which, taken in combination, indicate thatthe facility is likely to meet that level of required serviceability.1.3 The paragraphs in the Facility Rating Scale (see Figs.1-5) are indicative and not comprehensive. They are for quickscanning to estimate ap
6、proximately, quickly, and economicallyhow well a facility is likely to meet the needs of one or anothertype of occupant group over time. The paragraphs are not formeasuring, knowing, or evaluating how an office facility isperforming.1.4 This classification can be used to estimate the level ofservice
7、ability of an existing facility. It can also be used toestimate the serviceability of a facility that has been plannedbut not yet built, such as one for which schematic or prelimi-nary drawings and outline specifications have been prepared.1.5 This standard indicates what would cause a facility to b
8、erated (classified) at a certain level of serviceability but does notstate how to conduct a serviceability rating or how to assign aserviceability score. That information is found in PracticeE 1334. The scales in this classification are complimentary toand compatible with Practice E 1334. Each requi
9、res the other.1.6 This standard indicates what would cause a requirementto be classified as being at a specific level, but does not statehow to ascertain a requirement, or how to assign a specificlevel. This information is found in Practice E 1679. The scalesin this classification are complimentary
10、to and compatible withPractice E 1679. Each requires the other.1.7 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 applic
