Using Attached Sunspaces in Passive Solar Design

Increase home heating and cooling performance and boost savings quickly by adding attached sunspaces to existing structures.

Fig. 4-6: Attached sunspaces are an easy way to retrofit a home for passive solar, although they often don’t perform well. This all-glass attached sunspace must be covered during the late spring, summer, and fall to prevent overheating. All-glass attached sunspaces also tend to lose lots of heat at night and therefore must be isolated from living spaces by doors.
