Report From Cen Tc 129/Wg9 - Light And Energy Transmission, Thermal Insulation

EU standards of TC 129 "Glass in Building" are being established by glass manufacturers. In particular, WG9 of TC 129 standardized the procedures for the determination of luminous and solar properties of glazing and the calculation of thermal transmittance. Measurement procedures for thermal transmittance by means of a guarded hot plate or heat flow meters are considered in EN 674 and EN 675 respectively. In a new standard a calculation method is given for the evaluation of the balance through glazing between heat losses and useful heat gains by solar radiation entering the building.
