Double ZeroHouse

    • KB Home earned a U.S. DOE Zero Energy Ready Home certification on this highly efficient home they call the “Double ZeroHouse” because it is a net zero energy home producing as much energy as it uses in a year and because the home uses zero fresh water for irrigation with an onsite greywater recycling system.
    • Professionally installed high-performance windows let in daylight but keep out heat, and advanced solid-state lighting technology is used in 100% of the fixtures.
    • High-efficiency appliances including an ENERGY STAR refrigerator and a water-recycling dishwasher to conserve energy and water. Other water-saving features include WaterSense-rated plumbing fixtures, a motion-sensing kitchen faucet, real-time metering of water usage, and recycling of shower water for irrigation.
    • A professionally installed fresh air system brings fresh filtered air into the home while continually exhausting stale air. Low- and no-VOC paints and finishes also contribute to the EPA Indoor airPLUS certification.
