Standard Classification for Serviceability of an Office Facility for Typical Office Information Technology
SIGNIFICANCE AND USE
4.1 Each Facility Rating Scale (see Figs. 1-18) 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 the level of any other building or facility.
4.2 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. Further information may be found in ISO 19208.
4.3 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.
4.4 This classification can be used to estimate the following:
4.4.1 Serviceability of an existing facility for uses other than its present use.
4.4.2 Serviceability (potential) of a facility that has been planned but not yet built.
4.4.3 Serviceability (potential) of a facility for which remodeling has been planned.
4.5 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.
4.6 This classification applies only to facilities that are building constructions, or parts thereof. (While this classification may be useful in rating the serviceability of facilities that are not building constructions, such facilities are outside the scope of this classification.)
4.7 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.
SCOPE
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 performance to support typical office equipment for information technology.
1.2 Within that aspect of serviceability, each matched set of scales, shown in Figs. 1-18, are for classifying one topic of serviceability. Each topic is typically broken down into two more demand functions and supply features. Each paragraph in an Occupant Requirement Scale (see Figs. 1-18) summarizes one level of serviceability on that topic, which occupants might require. The matching entry in the Facility Rating Scale (see Figs. 1-18) 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.

Overview
ASTM E1663-22 is the Standard Classification for Serviceability of an Office Facility for Typical Office Information Technology, published by ASTM International. This standard offers a structured approach for classifying the serviceability of office facilities in supporting typical office information technology requirements. Serviceability, in this context, refers to how well a physical office environment meets occupant needs regarding the deployment and functioning of IT equipment and infrastructure.
The classification employs matched sets of scales-demand and supply-to assess and compare various aspects of serviceability across different buildings. The standard is versatile, useful for evaluating existing facilities, planned constructions, and potential remodels. It enables quick estimates on how office environments measure up against occupants’ requirements, supporting efficient decision-making for facility managers, building owners, and tenants.
Key Topics
ASTM E1663-22 covers essential factors impacting the suitability of office facilities for information technology:
Serviceability Scales: Offers paired demand (occupant requirements) and supply (facility features) scales for 18 critical topics, including:
- Density of office computers and equipment
- Location and availability of power sources
- Number of plug-in points at workstations
- Power distribution and supply reliability
- Horizontal and vertical cabling distribution (risers)
- Entrance facility for network services
- Serviceability of cable plant infrastructure
Applicability: The standard is valid for buildings regardless of location, age, structure, mechanical system, or shape, making it broadly useful for comparative evaluation.
Non-evaluative Role: While it provides structured classification, ASTM E1663-22 is not intended for building code compliance, fire hazard, or risk evaluation. Formal evaluation and diagnosis remain the domain of specialized engineering expertise.
Comprehensiveness: The classification does not cover code or regulatory requirements but is designed to supplement those, helping identify individual user needs and facility capabilities.
Applications
Practical uses of ASTM E1663-22 include:
Comparative Analysis: Facility managers and designers can compare the serviceability levels of different office environments using consistent criteria, supporting efficient selection or improvement strategies.
Design and Planning: Architects and planners can leverage the standard during the design phase of new office buildings or renovations to ensure that IT infrastructure requirements are met effectively.
Facility Assessment: Organizations can quickly assess the suitability of prospective office spaces or benchmark existing facilities as needs evolve, especially for IT-dependent operations.
Future Flexibility: By identifying gaps between demand and supply for IT serviceability, the standard supports planning for upgrades or modifications, ensuring office environments remain adaptable over time.
Tenant Communication: The classification scales provide a shared language and framework for discussing facility capabilities with potential users and stakeholders.
Related Standards
ASTM E1663-22 is complemented by other key standards that address specific aspects of office facility performance and IT infrastructure, including:
- ASTM E1334 and E1679: Practices for rating and setting serviceability requirements.
- ASTM E1666: Classification for serviceability under non-standard hours.
- ASTM E1694: Serviceability for special facilities and technologies.
- ASTM E2320: Thermal environment and indoor air conditions.
- ANSI/TIA-569-E: Commercial building standards for telecommunications pathways and spaces.
- ISO 19208: Framework for specifying performance in buildings.
Conclusion
Adopting ASTM E1663-22 provides valuable benefits for facility professionals assessing, comparing, and improving the IT serviceability of office buildings. By offering a repeatable and structured classification system, the standard enhances office planning, design, and ongoing management, ensuring workspaces are well-equipped to support evolving information technology needs.

1. Scope Scope*
1.1 This classification covers pairs 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 performance to support typical office equipment for
information technology.
1.2 Within that aspect of serviceability, each pair matched set of scales, shown in Figs. 1-618, are for classifying one topic of
serviceability. Each topic is typically broken down into two more demand functions and supply features. Each paragraph in an
Occupant Requirement Scale (see Figs. 1-618) summarizes one level of serviceability on that topic, which occupants might require.
The matching entry in the Facility Rating Scale (see Figs. 1-618) 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.
1.3 The entries in the Facility Rating Scale (see Figs. 1-618) 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 E1334E1679. The
scales in this classification are complimentary to, and compatible with, PracticesPractice E1334 and 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 remains
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.

3.1.1 facility—facility, n—a physical setting used to serve a specific purpose.
3.1.1.1 Discussion—
A facility may be within a building, a whole building, or a building with its site and surrounding environment; or it may be a
construction that is not a building. The term encompasses both the physical object and its use (see Terminology E631).
3.1.2 facility serviceability—serviceability, n—the capability of a facility to perform the function(s) for which it is designed, used,
or required to be used.
3.1.2.1 Discussion—
The scope of this performance is of the facility as a system, including its subsystems, components and materials and their
interactions, such as acoustical, hydrothermal, air purity, and economic; and of the relative importance of each performance
requirement (see Terminology E631).
3.1.3 offıce—offıce, n—a place, such as a room, suite, or building, in which business, clerical, or professional activities are
conducted (see Terminology E631).
