GSO ISO 9050:2007 Glass in building – Determination of light Transmittance , Solar direct transmittance , Total Solar Energy transmittance , Ultraviolet transmittance and related glazing factors
This International Standard specifies methods of determining light and energy transmittance of solar radiation for glazing in buildings. These characteristic data can serve as a basis for light, heating and ventilation calculations of rooms and can permit comparison between different types of glazing.
