18、 Committee CEN /TC 89, “Thermal performance of buildings and building components“ the secretariat of which is held by SIS. This document shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2008 and conflicting natio

20、ative. This standard consists of two parts: Part 1: Simplified method Part 2: !Detailed calculation method“ Due to the improved thermal properties of insulating glass units an adaptation of the notional parameter G was necessary. The scope of the standard was made more precise.“ According to the CEN

22、uxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. 1 Scope This European Standard specifies a simplified method based on the thermal transmittance and total solar energy transmittance of the glazing and on the light tr

23、ansmittance and reflectance of the solar protection device to estimate the total solar energy transmittance of a solar protection device combined with glazing. The method applies to all types of solar protection devices parallel to the glazing such as louvre, venetian or roller blinds. The position

24、of the solar protection device can be interior, exterior or between single panes in a dual glazing system. It is applicable when the total solar energy transmittance of the glazing is between 0,15 and 0,85. Venetian or louvre blinds are assumed to be adjusted so that there is no direct solar penetra

25、tion. It is assumed that for external solar protection devices and for integrated solar protection devices, the space between the solar protection devices and the glazing is unventilated and for internal solar protection devices this space is ventilated. !The resulting g-values of the simplified met

26、hod given here are approximate and their deviation from the exact values lie within the range between +0,10 and -0,02. The results generally tend to lie on the safe side for cooling load estimations. The results are not intended to be used for calculating beneficial solar gains or thermal comfort cr

27、iteria. The simplified method is based on the normal incidence of radiation and does not take into account either the angular dependence of transmittance and the reflectance or the differences of spectral distribution.

29、and 0,1 e,B 0,8 For reflectance and transmittance values outside these ranges EN 13363-2 1 applies. An allowance can be made for this fact when applying the method.
