ASTM E2320-04(2018)

4.1 Each Occupant Requirement Scale (see Figs. 1-5) in this classification provides a means to set the required level of serviceability of a building or facility for one topic of serviceability and to compare that level against any level of any other occupant, or of any building or facility.

4.2 Each Facility Rating Scale (see Figs. 1-5) in this classification provides a means to estimate the level of serviceability of a building or facility for one topic of serviceability and to compare that level against any level of requirement of any occupant, or of any other building or facility.

4.3 This classification can be used for comparing how well different buildings or facilities meet a particular requirement for serviceability. It is applicable despite differences such as location, structure, mechanical systems, age, and building shape.

4.4 This classification can be used to estimate the amount of variance of serviceability from target or from requirement, for a single office facility, or within a group of office facilities.

4.5 This classification can be used to estimate the following:

4.6 Use of this classification does not result in building evaluation or diagnosis. Building evaluation or diagnosis generally requires a special expertise in building engineering or technology, and the use of instruments, tools, or measurements.

4.7 This classification applies only to facilities that are building constructions, or part thereof. (While classification may be useful in rating the serviceability of facilities that are not building constructions, such facilities are outside the scope of this classification. See discussion under definition 3.1.1.)

4.8 This classification is not intended for, and is not suitable for, use for regulatory purposes nor for fire hazard assessment nor for fire risk assessment.

1.1 This classification contains pairs of scales for classifying an aspect of the serviceability of an office facility, that is, the capability of an office facility to meet certain possible requirements for suitable thermal environment and indoor air conditions.

1.2 Within this aspect of serviceability, each pair of scales, shown in Figs. 1-5,3 is for classifying one topic of serviceability. Each paragraph in an Occupant Requirement Scale (see Figs. 1-5) summarizes one level of requirement for serviceability on that topic, which occupants might require. The matching paragraph in the Facility Rating Scale (see Figs. 1-5) is a translation of the requirement into a description of certain features of a facility which, taken in combination, indicate that the facility is likely to meet that level of required serviceability.
