This green home is a modern addition to an existing single-family home, originally built in 1942. Utilizing both active and passive solar design, the home captures natural canyon breezes and uses large overhangs for cool shading. Other green features include high insulation, low-emissivity windows, certified Cool Roof, tankless water heaters, photovoltaic system, up-cycled building materials and a gray-water system to irrigate the drought-tolerant landscaping. The yard even includes a 16-square-foot solar-powered child's play fort.
