What is passive solar design and will it really save me money on heating & cooling costs?
Passive solar design is the correct orientation of the building to the suns path within fifteen degrees either side of true south, proper placement of windows for solar gain and ventilation, overhangs and other strategies to prevent overheating, and adequate storage mass within the house to reduce temperature swings in both summer and winter. Implementing passive solar design strategies can reduce heating and cooling loads by 10 to 20%, and make your home feel more comfortable. And please, never ever build your attached garage on the south side of your house.
