BS EN ISO 52022-3:2017 specifies a detailed method, based on spectral data of the transmittance and reflectance
of the constituent materials (solar protection devices and the glazing), to determine the total solar
energy transmittance, the total light transmittance and other relevant solar-optical data of the
combination. If spectral data are not available, the methodology can be adapted to use integrated data.
The method is valid for all types of solar protection devices parallel to the glazing such as louvres,
venetian blinds, or roller 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 the glazing or blind components, for vertical orientation of the glazing.
The blind component materials may be transparent, translucent or opaque, combined with glazing
components with known 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 of transmittance or reflectance of the materials. Diffuse irradiation or radiation diffused
by solar protection devices is treated as if it were direct. Louvres or venetian blinds are treated as
homogenous materials by equivalent solar optical characteristics, which may depend on the angle of the
incidence radiation. The current method is limited to vertical installation ?15?. For situations outside
the scope of this document; ISO 15099 covers a wider range of situations.
The document also gives certain normalized situations, additional assumptions and necessary
boundary conditions.
