Wathen Castenos Hybrid Homes - Net Zero

Wathen Castenos Hybrid Homes has been building energy efficiency into every new home as a standard for the better part of a decade. Every home in the new Visalia community comes with high efficiency HVAC, better-than-code insulation, instantaneous hot water heating, high performance windows, EnergyStar appliances, and a 2kW solar array. When WC Homes came to Southern California Edison’s Sustainable Communities program for design assistance on a “Zero Net Energy Option,” energy efficiency was taken to the next level. Any homeowner interested in going ZNE can select a building that improves the HVAC efficiency, adds LED lighting throughout, includes an energy management system, and an upgraded 8 kW rooftop solar array capable of producing more renewable energy than the building uses.
