This European Standard specifies a calculation method to determine the energy balance value of glazing. This

European Standard applies to transparent materials such as glass and combinations of glass used to glaze

windows in buildings.

This method is intended to evaluate the balance of heat loss and useful heat gain by solar radiation entering the

building through the glazing for a given period by means of an average rate of loss (or gain) of heat called the

energy balance value.

The method enables producers to compare the performance of their glazing products. The energy balance value

should not be used for energy use or heating capacity calculations in buildings.
