One thing that I have heard some people talking about is using solar air heat (solar furnace) for pre-heating ventilation makeup air in larger buildings. From what I’ve heard, it could more or less eliminate the need to heat the air with fossil fuels, even here in chilly Minnesota. If you wanted to learn more, I know that Jason Edens at Rural Renewable Energy Alliance (RREAL) would be happy to tell you what they’ve learned: http://rreal.org.

How can that be achieved without introducing cold ambient air and having to heat it to room temperature?
