Webrepresents the Solar Heat Gain Coefficient (SHGC) of the glass. This is the transfer of heat from solar irradiated glass to the occupied space. The third term (the U (t o-t i)) represents the overall conductive heat transfer through the glass considering the differences between the interior and exterior temperature only. In this respect,if the Solar gain is most frequently addressed in the design and selection of windows and doors. Because of this, the most common metrics for quantifying solar gain are used as a standard way of reporting the thermal properties of window assemblies.
