2020 Featured Home
This 1979 home's windows, ceilings and walls are transformed to exceed the performance of new “net zero energy’’ homes. The solar PV and solar-collecting south surfaces, seven jumbo sun tunnels, five skylights, and 91 square feet of solar floors capture sunlight for electricity, heating, lighting, citrus fruit production and powering a Tesla. The home is still able to supply 10,000 kwH of surplus electricity to the grid. Additions include 14 super insulated airlock entry rooms, built using surplus material, which combine with highly efficient walls to buffer the home’s indoor climate. No natural gas is used; all heating is provided by heat pumps. Water is collected for the gardens and vineyards outside.
