The design for this stunning California home managed to achieve net-zero electrical use and a LEED Silver rating.
Energy use is 38% below Title 24 requirements, and an integrated design process delivered a superbly comfortable and beautifully lit
home with many sustainable and energy efficient features, including:
Owner desired west (ocean) and east (valley) views; long east-to-west gabled ridge provides south-facing roof for 44 solar/PV panels to provide 100% of electrical needs; 9.9 KW
Concrete slabs and retaining walls provide passive cooling, no AC needed
South facing overhangs calculated to provide shading of glass in summer and solar gain to stone floors in winter.
Trellises at west-facing gabled ends, dining room and gazebo increase summer shading
Dual-glazed low e2 windows for high energy performance
Carefully located operable windows provide through ventilation that take advantage of prevailing winds
Thermostatically controlled exhaust fans dump hot/stagnant air from ridges
Ridge skylights, skylights and roof monitor provide interior daylighting to reduce need to turn on lights during the day
