9、iling clients of the SABS.Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of developing International Standards is carried out through IS0 technical committees. Every member body interested in a su
10、bject for which a technical committee has been authorized has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulat
11、ed to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 6241 was developed by Technical Committee ISO/TC 59, Bulding construction, and was circulated to the member bodies in December 1982. It has been approved by the memb

14、the SABS.INTERNATIONAL STANDARD IS0 6241-1984 (E) Performance standards in building - Principles for their preparation and factors to be considered 0 Introduction The development of performance standards for building in- volves work at all levels from fundamental to specific. The aim is to define th
15、e performance required of whole buildings, parts of buildings and building products in terms of the functional re- quirements of their users. The work includes the preparation of : a) fundamental (level 1) standards on the general prin- ciples of defining performance requirements and establishing st
16、andard methods for their evaluation, such IS0 6240 and IS0 71621); b) fundamental standards on the means of expression which user requirements can be communicated, such IS0 62422); c) fundamental standards concerning the definition agents relevant to building performance, such IS0 62433); of as bY a
17、s of as d) wide-ranging and specific (levels 2 and 3) standards for the performance of particular types of building or product and on methods for assessing individual performance at- tributes. These would be prepared by committees respon- sible for the particular items. This International Standard i
18、s a guide to level 1 standards, in- tended primarily to assist standards committees in their work by stating the general principles for drafting performance stan- dards for building. It includes four tables aimed at identifying the main factors to be considered in their elaboration, i.e. a) the user
19、 requirements (table 1); b) the possible uses of the buildings and their spaces (table 2); c) the building sub-systems of which the product is a part (table 3); d) the agents, of any nature and origin, which are relevant to the performance of the product in use (table 4). These tables may also serve
20、 to arrange the items given in the standards; it is particularly recommended that the performance of a product is stated in the order of the user requirements which it has to meet. The tables are not exhaustive. Their relationship to current classification systems for building documentation is indic
21、ated. 1 Scope This International Standard lays down general principles for the preparation of performance standards in building. It complements IS0 6246 by listing factors to be considered for performance standards. 2 Field of application This International Standard is intended to assist standards c
22、ommittees concerned with the performance of whole buildings, of parts of buildings (components, assemblies and sub-systems) and of the spaces within and around buildings. The principal uses envisaged are : a) as a basis for the preparation of performance standards; b) as an aide-mt+moire for draftin

The contents of, and the order of the clauses in, standards should comply with IS0 6240. performance When dealing with components, they permit different products as solutions in alternative designs or materials (f
34、or example, windows of wood, steel, aluminium or plastics). Performance standards define requirements without imposing restrictions on the form or materials of the solutions. It has to be stressed that performance standards are aids to, but not substitutes for, design. It may be convenient for metho
35、ds of assessment to be given in documents separate from the performance standards to which they relate. The contents and presentation of standards or parts of standards defining methods of assessment should comply with IS0 7162. See footnote 1) to clause 0.1 5.4 Methods of assessment or verification

42、 the calculation of the overall resultant temperature of a room from its thermal properties, its airtightness, its heat in- put from heating appliances and external environmental conditions; b) the estimation of the evacuation time of a building from the occupancy of its rooms and the sizes and arra
43、ngement of escape routes; C) the calculation of the serviceability limit state of a wall, based on the strength of its materials and its stress distribution. 5.4.4 Judgement A judgement or appraisal can permit the extent of satisfaction of performance requirements to be assessed on the basis of ex-
44、perience of similar cases and conditions or compliance with well-established solutions. 5.4.5 Choice of method In most cases, and particularly when developing or checking a design before construction, it will be possible to determine whether a building as a whole satisfies its user requirements from
45、 a calculation or an assessment based on the performance of its parts. However, in some situations (for example with an innovative design, or when reappraising an existing building) or for some performance requirements (for example ventilation, acoustics), the extent of satisfaction of user requirem
46、ents may need to be assessed in part by direct measurement or test of the building itself, or of a sample or prototype. The choice of a method of assessment or verification depends also on the level of accuracy appropriate to the relative impor- tance and the order of priority of the performance req
47、uirement. 6 sta Factors ndards to be considered in performance 6.1 User requirements (table I) 6.1.1 Table 1 lists the user requirements, which the building should satisfy, in various categories. They apply to spaces within (or around) buildings considered independently of their location and design.
48、 The performance requirements apply to the building fabric and its sub-systems. They are derived from the user requirements by taking account of the building location and initial design decisions. The requirements are the same, but they are expressed dif- ferently; for example, in the case of therma
49、l comfort in winter: - user requirement: a minimum internal air temperature of 20 OC shall be achieved on all but 3 days per year, on average; - performance requirement: a minimum internal air temperature of 20 OC shall be achieved when the daily mean outside air temperature is -2 OC or above (assuming this to be the low extreme reached or surpassed on an average of 3 days per year on a particular site). 6.1.2 Table 1 is a master list, so that in any one case only a selection of the requirements will apply. For product standar- dization, the list serves as an aide-memoire to identif
