6、for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). 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 t

7、he right to be represented on that committee. International organizations, governmental and 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. Interna

8、tional Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publicatio

9、n as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights

BS ISO 16818:2008vIntroduction This International Standard is intended to provide general terms and definitions used in building environment design.

36、ire insulation or weather-stripping. The outer shell of the building is not necessarily the same as the building envelope, particularly where the building contains semi-heated or unconditioned spaces. NOTE 2 In some cases, the designer can determine the location of the exterior building envelope by

37、the location that they place the insulation. For instance, it is not uncommon for a stairwell to be at the outside edge of the building. If that stairwell does not have any heating or cooling supply, it can be insulated on the outside edge or the side adjacent to other heated or cooled space. If ins

38、ulated on the outside, the stairwell becomes indirectly conditioned and the outside wall is the exterior building envelope. If insulated on the inside, the inside wall is likely to become the exterior building envelope (unless the outside exposure is so small that it would still be indirectly condit

39、ioned space). NOTE 3 Where a building with conditioned space also contains semi-heated spaces or unconditioned spaces, the building envelope for the conditioned space is the roofs, walls, floors, doors, fenestration, etc. that separate the conditioned space from the exterior. These elements shall co

40、mply with the residential or non-residential conditioned space requirements. NOTE 4 For semi-heated spaces, the building envelope includes any roofs, walls, floors, doors, fenestration, etc. that separate the semi-heated space from conditioned or unconditioned spaces (as well as from the exterior).

41、These elements shall comply with the semi-heated space requirements, as shall elements separating conditioned space from unconditioned space. 3.29 building exit any doorway, set of doors, or other form of portal that is ordinarily used for emergency egress or convenience exit 3.30 building grounds l
