Understanding of Solar Heat Gain Coefficient
Ranked else to consider is the solar heat gain coefficient. It measures the solar radiation that is released into the house. The lower the solar heat gain coefficient, the less heat is released, which is ideal for a warm climate throughout the year.
On the other hand, a high solar heat gain coefficient means that the window will help to keep the house warm in winter and in cold climates. There is no one perfect solar heat gain coefficient for all climates so you have to choose the right one based on where you live, as well as the orientation of the wall.
