This document specifies methods of determining the luminous and solar characteristics of glazing in buildings, incorporating at least one light-scattering material. These characteristics can serve as a basis for lighting, heating and cooling calculations of rooms and permit comparison between different types of glazing.
This document applies both to conventional glazing and to absorbing or reflecting solar-control glazing, used as vertical or horizontal glazed apertures. The appropriate formulae for single, double and triple glazing are given.
This document includes a method to determine the luminous and solar properties of Building-Integrated Photovoltaic (BIPV) glazing incorporating at least one light-scattering material.
This document is accordingly applicable to all transparent materials except those which show significant transmission in the wavelength region 5 µm to 50 µm of ambient temperature radiation, such as certain plastic materials.
For the determination of the luminous and solar characteristics of glazing in buildings, without light-scattering materials, please refer to EN 410-1.
