Solar gain through glass
WebUsing larger south-facing glass than this limit can lead to overheating even in winters. For instance, passive solar system for 140 m 2 house may consist of 14 m 2 of direct gain glazing (Figure-4) and 11 m 2 of sunspace glazing (Figure-5). The total solar glazing is 25 m 2 which is 18% of total floor area. WebSolar Heat Gain Coefficient (SHGC) is a measure of how much solar energy passes through a window, expressed by a ratio in the range of 0 to 1. Figure 1 (a) illustrates an example of …
