PASSIVE COOLING A cross-section of a home with a solar chimney is shown. The solar chimney draws replacement air from the cool side of the house. Solar radiation absorbed by a metal absorber with a black selective coating causes high temperatures in the chimney, increasing updraft. Hot air exits the chimney through a rotating turbine at the top. The house-facing side of the chimney is insulated.
To add passive cooling to the house you can utilize what are sometimes called “Geo-coupled thermal tubes”, simple pipes or passages below ground where hot air is cooled before entering the shelter....SO AWESOME!
Passive Cooling: Rock Wall. A Natural Thermostat: "Large rocks squeezed into together by 'wood shelves' insulate the South face of the house. The rocks absorb the heat during the day lowering the solar gain. At night the rocks give heat back into into the air as the temperature outside drops. The rock wall and the desert climate work in concert to passively cool the house."
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.
