1.1 该分类涵盖了一组匹配的尺度，用于对办公设施的可用性进行分类，即办公设施满足布局和建筑因素某些可能要求的能力。 1.2 在可用性方面，每个匹配的量表集如所示 无花果。1- 12 ，用于对一个可用性主题进行分类。每个主题通常分为两个或两个以上的需求函数或供应特征。乘员需求量表中的每个段落（参见 无花果。1- 12 )总结了乘员可能需要的该功能的一个可用性级别。设施评级表中的匹配条目（参见 无花果。1- 12 )是将要求转化为设施某些特征的描述，结合起来，表明设施可能满足所需的可用性水平。 图1 布局约束的需求规模A.7.1.1 图2 人口密度约束的需求量表A.7.1.2 图3 升级成本需求量表A.7.1.3 图4 提供比例A.7.1.1，以限制布局 图5 支持人口密度的供应规模A.7.1.2 图6 升级成本的供应规模A.7.1.3 图7 声音和视觉条件容差的需求量表A.7.2.1 图8 需求量表A。 7.2.2避免监视器上的眩光 图9 供应规模A.7.2.1布局约束 图10 供应比例A.7.2.2避免监视器上的眩光 图11 建筑损失特征对空间需求影响的需求量表A.7.3 图12 供应规模A.7.3建筑损耗特性对空间需求的影响 1.3 设施评级表中的条目（参见 无花果。1- 12 )仅供参考，但不全面。它们用于快速扫描，以大致、快速和经济地估计办公设施随着时间的推移可能满足一种或另一种类型居住群体的需求的程度。这些条目不是为了衡量、了解或评估办公设施的表现。 1.4 该分类可用于评估现有设施的可用性水平。它还可用于估计已规划但尚未建造的设施的可用性，例如已编制单线图和轮廓规范的设施。 1.5 该分类表明了什么会导致设施被评为某一可用性水平，但没有说明如何进行可用性评级，也没有说明如何分配可用性分数。在实践中可以找到这些信息 E1679 . 该分类中的量表是对实践的补充和兼容 E1679 . 每一个都需要另一个。 1.6 这些比例旨在确定特定用户特有的各种需求水平，以及建筑物满足这些需求的可用性（能力）。因此，比例尺补充而不是包括规范要求。设计师、建筑商和建筑经理仍有责任满足与其在设施设计、施工和日常管理中各自角色相关的适用规范要求。 1.7 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 每个设施评级表（见 无花果。1- 12 )在该分类中，提供了一种方法来估计建筑物或设施对一个可用性主题的可用性水平，并将该水平与任何其他建筑物或设施的水平进行比较。 4.2 该分类可用于比较不同建筑物或设施满足特定可用性要求的程度。尽管存在位置、结构、机械系统、年龄和建筑形状等差异，但它仍然适用。 4.3 该分类可用于估计单个办公设施或一组办公设施内的可用性与目标或需求的差异量。 4.4 该分类可用于估计以下各项: 4.4.1 现有设施对其当前用途以外的用途的可用性。 4.4.2 已规划但尚未建造的设施的可用性（潜力）。 4.4.3 已计划改建的设施的可用性（潜力）。 4.5 使用该分类不会导致建筑物评估或诊断。建筑评估或诊断通常需要建筑工程或技术以及仪器、工具或测量的使用方面的专业知识。 4.6 该分类仅适用于建筑结构或其部分的设施。（虽然该分类可能有助于评估非建筑设施的可用性，但此类设施不在该分类的范围内。） 4.7 该分类不适用于监管目的，也不适用于火灾危险评估或火灾风险评估。

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.

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. ====== Significance And Use ====== 4.1 Each Facility Rating Scale (see Figs. 1- 12 ) 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. 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.
