Good, clear presentation of Seasonal Window Considerations for Passive Solar homes. Windows must be climate sensitive: check to see if they show be double or triple paned, or even covered with a thermal shade in coldest climates.
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.
