This unique 241 square foot all solar design qualifies as a zero energy home. It’s for desert regions only. The home is cooled with water trickling over the metal roofing using the same evaporative cooling principle as found in the original Desert Submarine. It’s a simple yet proven technology. Solar panels power the water pumps, lights and other electrical needs. A solar hot water heater provides domestic hot water. Electronic controls regulate the flow of water to maintain interior temperatures. The main structure consists of steel studs covered in galvanized metal roofing. Earthbag walls help keep the home comfortable year-round.
