適用范圍：This document specifies a detailed method, based on the spectral transmission data of the materials, comprisingthe solar protection devices and the glazing, to determine the total solar energy transmittance and other relevantsolar-optical data of the combination. If spectral data are not available the methodology can be adapted to use integrateddata.The method is valid for all types of solar protection devices parallel to the glazing such as louvres, or venetian, orroller blinds. The blind may be located internally, externally, or enclosed between the panes of the glazing.Ventilation of the blind is allowed for in each of these positions in determining the solar energy absorbed by theglazing or blind components, for vertical orientation of the glazing.The blind component materials may be transparent, translucent or opaque, combined with glazing components withknown solar transmittance and reflectance and with known emissivity for thermal radiation.The method is based on a normal incidence of radiation and does not take into account an angular dependence oftransmittance or reflectance of the materials. Diffuse irradiation or radiation diffused by solar protection devices istreated as if it were direct. Louvres or venetian blinds are treated as homogenous materials by equivalent solaroptical characteristics, which may depend on the angle of the incidence radiation. For situations outside the scopeof this document; ISO 15099 covers a wider range of situations.The document also gives certain normalised situations, additional assumptions and necessary boundaryconditions.
