21、nization 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 establis

22、hed 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 matters of electrotechnical standardization

23、. 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 circulated to the member bodies for voting. P

24、ublication 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 pate

25、nt rights. ISO 10077-1 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 10077-1:2000), the following clauses and subclauses of which hav

26、e been technically revised.

30、mittance: Part 1: General Part 2: Numerical method for frames EN ISO 10077-1:2006vIntroduction The calculation method described in this part of ISO 10077 is used to evaluate the thermal transmittance of windows and doors, or as part of the determination of the energy use of a building. An alternativ

31、e to calculation is testing of the complete window or door according to ISO 12567-1 or, for roof windows, according to ISO 12567-2. The calculation is based on four component parts of the overall thermal transmittance: for elements containing glazing, the thermal transmittance of the glazing, calcul

32、ated using EN 673 or measured according to EN 674 or EN 675; for elements containing opaque panels, the thermal transmittance of the opaque panels, calculated according to ISO 6946 and/or ISO 10211 (all parts) or measured according to ISO 8301 or ISO 8202; thermal transmittance of the frame, calcula

33、ted using ISO 10077-2, measured according to EN 12412-2, or taken from Annex D of this part of ISO 10077; linear thermal transmittance of the frame/glazing junction, calculated according to ISO 10077-2 or taken from Annex E of this part of ISO 10077. More detailed equations for calculation of heat f

34、low through windows can be found in ISO 15099. The thermal transmittance of curtain walling can be calculated using prEN 13947. EN 13241-1 gives procedures applicable to doors intended to provide access for goods and vehicles. EN ISO 10077-1:2006blank1Thermal performance of windows, doors and shutte

35、rs Calculation of thermal transmittance Part 1: General 1 Scope This part of ISO 10077 specifies methods for the calculation of the thermal transmittance of windows and pedestrian doors consisting of glazed and/or or opaque panels fitted in a frame, with and without shutters. This part of ISO 10077

36、allows for different types of glazing (glass or plastic; single or multiple glazing; with or without low emissivity coatings, and with spaces filled with air or other gases); opaque panels within the window or door; various types of frames (wood, plastic, metallic with and without thermal barrier, m

37、etallic with pinpoint metallic connections or any combination of materials); where appropriate, the additional thermal resistance introduced by different types of closed shutter, depending on their air permeability. The thermal transmittance of roof windows and other projecting windows can be calcul

38、ated according to this part of ISO 10077, provided that the thermal transmittance of their frame sections is determined by measurement or by numerical calculation. Default values for glazing, frames and shutters are given in the informative annexes. Thermal bridge effects at the rebate or joint betw

39、een the window or door frame and the rest of the building envelope are excluded from the calculation. The calculation does not include effects of solar radiation, heat transfer caused by air leakage, calculation of condensation, ventilation of air spaces in double and coupled windows, surrounding pa

40、rts of an oriel window. The part of ISO 10077 does not apply to curtain walls and other structural glazing, industrial, commercial and garage doors.
