Q

Direct Gain Systems

A

Defenestration. Simplest passive solar home design technique. Sunlight enters the house through windows without interference and the heat collection, storage and distribution all occur within the same space.
When light reaches floors and walls, they absorb and store the solar heat.
At night the stored heat energy warms the room through convection and radiation
