Passive solar heating is a heating system with only one moving part: the sun. (Actually, the sun doesn't more; it's the Earth whose revolutions on its axis give rise to sunrises and sunsets.) Passive solar design provides space heat for all kinds of buildings from homes to offices to fire stations to airports to schools. You name it, passive solar can be used to warm the interior.
 
Passive solar design relies on ordinary visible light from the low-angled winter sun, which penetrates south-facing windows during the heating season. Insider our homes, the sun's visible light is absorbed by floors, walls, and other solid materials. Here it is converted to heat that warms our homes and other buildings.
 
If you would like Simply Efficient to help you retrofit your existing home or commercial property or design your new project with the benefit of passive solar design, please request an estimate or call us today for a consultation.
