    • Insulsteel Building Enclosures built this 3,700-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.
    • Energy- and water-saving measures incorporated in this ENERGY STAR-certified home are estimated to save $4,000 per year and $167,000 over a 30-year mortgage. The high-performance home also received a LEED platinum rating from the U.S. Green Building Council.
    • The 6.8 kilowatts of solar photovoltaic panels on the roof contribute $1,200 to the annual energy cost savings of $2,350 this high-performance home is expected to achieve compared to a home built to the 2012 International Energy Conservation Code.
    • The refrigerator, dishwasher, and ceiling fans are ENERGY STAR certified. The quartz countertops are manufactured from recycled materials.
    • ENERGY STAR-rated LED lighting was used throughout the home.
    • The impact-resistant triple-pane windows have an insulating argon gas fill between the panes. Low-emissivity coatings reflect heat to help keep the home warmer in winter and cooler in summer; the coatings also block 99% of damaging ultraviolet light.
    • A fresh air intake brings in fresh outside air that is filtered through a MERV 13 filter and an ultraviolet light filter before being distributed throughout the home via the high-velocity duct system.
    • The water-saving faucets, showers, and toilets that were chosen carry the EPA WaterSense label, meaning they meet strict specifications for water efficiency and performance.
    • A programmable thermostat allows the homeowners to both manage and monitor their energy usage, even remotely.
    • Low- and no-VOC paint, sealants, finishes, and flooring helped the home qualify for the EPA's Indoor airPLUS air-quality label.

      We love our new energy-efficient home knowing that our initial investment will pay for itself over the next 10 years. It’s a pleasure opening our electrical bill to see the lowest amounts we have ever paid. Our HVAC system is very quiet and the LEDs are cool to the touch. What is not to love in our new energy-efficient home!
