ASTM E 1664:2019

1.1 This classification covers matched sets 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 layout and building factors. 1.2 Within that aspect of serviceability, each matched set of scales, shown in Figs. 1- 12 , are for classifying one topic of serviceability. Each topic is typically broken down into two or more demand functions or supply features. Each paragraph in an Occupant Requirement Scale (see Figs. 1- 12 ) summarizes one level of serviceability on that function, which occupants might require. The matching entry in the Facility Rating Scale (see Figs. 1- 12 ) 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. FIG. 1 Demand Scale A.7.1.1 for Constraints on Layout FIG. 2 Demand Scale A.7.1.2 for Constraints of Population Density FIG. 3 Demand Scale A.7.1.3 for Cost of Upgrade FIG. 4 Supply Scale A.7.1.1 for Constraints on Layout FIG. 5 Supply Scale A.7.1.2 for Population Density Supported FIG. 6 Supply Scale A.7.1.3 for Cost of Upgrade FIG. 7 Demand Scale A.7.2.1 for Tolerance of Sound and Visual Conditions FIG. 8 Demand Scale A.7.2.2 Avoiding Glare on Monitors FIG. 9 Supply Scale A.7.2.1 Constraints on Layout FIG. 10 Supply Scale A.7.2.2 Avoiding Glare on Monitors FIG. 11 Demand Scale A.7.3 for Influence of Building Loss Features on Space Needs FIG. 12 Supply Scale A.7.3 Influence of Building Loss Features on Space Needs 1.3 The entries in the Facility Rating Scale (see Figs. 1- 12 ) are indicative and not comprehensive. They are for quick scanning to estimate approximately, quickly, and economically, how well an office facility is likely to meet the needs of one or another type of occupant group over time. The entries are not for measuring, knowing, or evaluating how an office facility is performing. 1.4 This classification can be used to estimate the level of serviceability of an existing facility. It can also be used to estimate the serviceability of a facility that has been planned but not yet built, such as one for which single-line drawings and outline specifications have been prepared. 1.5 This classification indicates what would cause a facility to be rated at a certain level of serviceability but does not state how to conduct a serviceability rating nor how to assign a serviceability score. That information is found in Practice E1679 . The scales in this classification are complimentary to and compatible with Practice E1679 . Each requires the other. 1.6 The scales are intended to identify the levels of various requirements unique to a particular user, and the serviceability (capability) of a building to meet those requirements. The scales thus supplement rather than include code requirements. It remain the responsibility of designers, builders, and building managers to meet applicable code requirements relative to their respective roles in facility design, construction, and ongoing management. 1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
