Passive Cooling: Rock Wall

Passive Cooling: Rock Wall. A Natural Thermostat, originally uploaded by Jeremy Levine Design.

Project: Three Trees
Location: Eagle Rock, California

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.
