    • Insulsteel Building Enclosures built this 2,967-square-foot home on Johns Island, South Carolina, to the performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
    • The house is designed to save $1,650 in energy costs compared to a home built to the 2012 International Energy Conservation Code.
    • The house is built on piers to increase resistance to floods. Spray foam insulates and air-seals the underside of the floor above the garages and storage areas.
    • Solar energy provides $1,200 in energy cost savings per year.
    • Solar thermal panels on the home's east- and south-facing roof slopes provide most of the heat for the home's two 40-gallon hot water storage tanks. Solar electric panels installed on the roof have a production capacity of 6.0 kW. Although tied to the grid, they also keep a battery charged to provide power to critical needs in case of a power outage.
    • Ultra-efficient triple-paned windows have low-emissivity coatings on three surfaces for exceptional heat blocking; they perform at least 50% better than a standard window.
    • All can lights are equipped with ultra-efficient light emitting diodes (LEDs).
    • The refrigerator and dishwasher are ENERGY STAR certified.
    • The quartz countertops are manufactured from recycled materials.
    • The home meets the requirements of the U.S. Environmental Protection Agency's Indoor airPLUS certification including the use of wood products, primer, paint, cabinets, and flooring that release few or no air contaminants.

      It’s about extreme energy efficiency and air quality. ... We have homes that are 3,000 square feet that have $15 or $20 electric bills. That’s the bottom line, to get lower energy costs and just avoid waste.
