ZeroHouse 2.0

    • KB Home's ZeroHouse 2.0 in San Marcos, California, is a certified U.S. DOE Zero Energy Ready Home equipped with solar electric panels on the roof that can meet all of the home's annual electric needs.
    • Advanced solid-state lighting technology is used throughout the home.
    • A solar electric system provides electricity for the home and an electric car charging station, while a solar thermal system provides much of the hot water for the home. A high-efficiency tankless gas water heater provides backup heat when the solar water heater cannot meet demand.
    • The ultra-efficient performance is distinguished with a label that clearly shows significant utility bill savings.
    • Big signs and media tours announced the home's completion and energy-efficient performance projected to save $3,783 per year in energy costs compared to a minimum-code home.
    • The home's water-saving fixtures, which meet EPA's WaterSense requirements, are demonstrated for visitors.
