6、odies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental a
7、nd non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are
8、described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is dr

13、(E) Introduction The performance concept has historically been used to address fitness for intended use of attributes of a building as a whole or a part thereof. Each characteristic is assessed in terms of whether or not it meets assumed performance. Over the last decade, this concept has been expan
14、ded to be used to address the beneficial or adverse impact of choices made regarding building materials, construction methods and resources, operating energy, water services and sanitary systems on economic conditions, the environment, a society or the quality of life, i.e. the contribution which a
15、building makes to sustainable development. This document provides the necessary framework and principles to describe the performance of a building or a part thereof either in terms of fitness of purpose or beneficial and adverse impacts and to provide the means of evaluation for solutions for all th
16、ese applications. This document is intended to assist anyone concerned with specifying performance of attributes and aspects of a building or a part thereof. Those include regulators, specifiers and suppliers, as well as international and national standards committee members. Specifying performance
17、of a building ranges from fundamental to specific. This document is intended primarily to assist those who are involved in specifying performance in buildings by stating general principles. It includes tables aimed at identifying the main factors to be considered in their elaboration. a) User requir
18、ements and societal expectations, b) possible uses of the buildings and their spaces, c) building subsystems of which the product is a part, and d) agents, of any nature and origin, which are relevant to the performance of a building and related entities in use, and affecting factors. Documents that
19、 specify performance may take various forms or features, such as regulations, specifications, or product standards. Annex B gives an example of application of the principles embodied in this document. ISO 2016 All rights reserved v Framework for specifying performance in buildings 1 Scope This docum
20、ent provides the framework for specifying the performance of a building as a whole or a part thereof in order to satisfy specified user requirements and societal expectations. This document covers buildings as constructed and inbuilt fixed components. It does not cover a) the use of the land for bui
21、ldings, b) the design and operation of the environment within which buildings are located, and c) moveable contents within buildings. NOTE 1 Guidance on the application of certain clauses is provided in Annex A. NOTE 2 A part of a building includes subsystems, spaces, elements, assemblies, component
22、s, products and materials. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

39、ion of property. They may also relate to contributions to sustainable development. Performance may be categorized into the following four types: a) reaction to agents; b) influence on human activities; c) impact on society; d) change in performance over time. The performance of a building as a whole
40、 may vary from its parts. The performance of a part of a building, such as a subsystem, element or component may also influence the performance of a building as a whole. The relationship between a part of a building and the whole of the building depends upon its intended or designed role. There are
41、forward and backward linkages between the building as a whole and its parts, such as subsystems, spaces, elements, assemblies, components, products and materials, as illustrated in Figure 1. Accordingly, an objective and associated performance of a part of a building need not be identical to the obj
42、ective and performance specified for the building as a whole. For example, if the object of the building as a whole is to minimize operational energy usage, the objectives for walls and floors may relate to thermal performance. On the other hand, a part of a building may have multi-faceted objective
43、s derived from the multi-faceted performance of the building as a whole. For example, a wall might be required to satisfy thermal, tightness and structural performance requirements. Performance specified for a component should be project specific and not generic as the context within which the compo
44、nent is used needs to be considered.4 ISO 2016 All rights reserved ISO 19208:2016(E) Figure 1 Hierarchical structure of the performance of a whole building and its parts 4.2 Model for specifying performance 4.2.1 Four level model The four level model shown in Figure 2 shall apply for specifying perf
45、ormance of a building as a whole or as a part. However, the contents of its description and its nature will differ depending on which attribute is under consideration. 4.2.2 Structure of the multiple layer model 4.2.2.1 Objective Objectives of a building as a whole are directly related to user requi
46、rements or societal expectations. Table 1 lists the commonly encountered subject matter of objectives. The common drivers for objectives associated with contributions to sustainability are indicated in Table 2. Objectives of parts of a building may be determined by the intended use or the way they a
47、re related to other parts or the building as a whole.
