Passive Solar Energy
Read free. “‘Passive’ solar heating and cooling does not depend on pumps or fans or any other devices. Instead, it relies on the natural ebb and flow of the energy of the sun through a house. With a few facts from this book and a little common sense, you can combine passive solar design with energy conservation and reduce the heating and cooling bills for a new house to less than 15% of those for conventional houses. And many of the ideas can be adapted to existing houses as well.”
