Passive Solar Projects

'Passive solar' is a term for a house or building that is built to make full use of solar energy in the form of natural sunlight. From its foundation to its windows, a passive solar house is designed to gather and retain heat from a free and natural source: the sun. Such houses have substantially less expensive heating bills than standard houses of the same size. I have built two such houses in my years of construction, the first one being my own.
