1、Designation: E2320 04 (Reapproved 2012) An American National StandardStandard Classification forServiceability of an Office Facility for Thermal Environmentand Indoor Air Conditions1,2This standard is issued under the fixed designation E2320; the number immediately following the designation indicate
2、s the year oforiginal 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 contains pairs of scales f
3、or classify-ing 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
4、 classifying one 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 re
5、quirement into 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
6、 to estimate approximately, 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
7、level ofserviceability 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
8、a facility to berated (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 PracticeE1334. The scales in this classification are complimentary toand compatible with Practice E133
9、4. Each requires 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 E1679. The scalesin this classification are co
10、mplimentary to and compatible withPractice E1679. 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
11、 the applica-bility of regulatory requirements prior to use.2.
