Cool, California ranch house in San Francisco is a sustainable gem

AGreenLiving

San Francisco-based firm Malcolm Davis Architecture has managed to combine the cool vibe of Cali design with the energy-saving principles of sustainable living. The operable glass doors and ultra-large windows provide optimal cross ventilation for natural cooling throughout the home. The home also has an integral greywater harvesting system that reroutes rainwater to be used to flush toilets and irrigate the landscaping.
