A Trombe wall is a passive solar building technique where a wall is built on the winter sun side of a building with a glass external layer and a high heat capacity internal layer separated by a layer of air. Heat in close to UV spectrum passes through the glass almost unhindered then is absorbed by the wall that then re-radiates in the far infrared spectrum which does not pass back through the glass easily, hence heating the inside of the building.

we love ours, closed loop and an unexpected perk is that the winter indoor air in our house improved (nicer on our skin and chests) over the propane furnace ...no regrets.

Earth Tubes passive heating/cooling system instead of A/C or heating. My dad has told me about this before. I want this in my home if I can talk Josh into it.
