15、ved Foreword ISO (the International Organization 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
16、 a technical committee has been established 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all mat
17、ters of electrotechnical standardization. International 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 circu
18、lated to the member bodies for voting. Publication 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 responsi
19、ble for identifying any or all such patent rights. ISO 13370 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 2, Calculation methods. This second edition cancels and replaces the first edition (ISO 13370:1998), which has bee
20、n technically revised. The following principal changes have been made to the first edition: Clause 4 contains a revised text to clarify the intention of the initial part of the former Annex A; the rest of the former Annex A is now contained in ISO 10211; 7.2 no longer contains a table of linear ther
21、mal transmittances: it is now recognized, as with other thermal bridging, that the wall/floor junction often needs to be calculated; 9.1 provides an alternative formula for well-insulated floors; 9.2 provides clarification for low-emissivity surfaces; Annex A contains formulae for cooling applicatio
22、ns; Annex B has incorporated minor revisions to the text for edge-insulated floors; Annex D has been revised; Annex F (formerly Annex C) has been changed to informative status.

24、ts and services make to energy conservation and to the overall energy performance of buildings. In contrast with ISO 6946, which gives the method of calculation of the thermal transmittance of building elements in contact with the external air, this International Standard deals with elements in ther
