Passive Solar Heating

Passive solar is the most cost effective approach to maximizing solar energy for your home. Passive solar heating occurs when sunlight passes through a window, and no additional equipment is used to harness the energy.  Passive solar applications use building elements such as walls, windows, floors and roofs, in addition to exterior building elements. Landscaping can control overheating by providing shade and winter windbreaks. Once heat is collected inside, a well-insulated airtight “building envelope” helps prevent heat loss.
