High-Performance Bungalow

    • Imery & Co. constructed the High-Performance Bungalow, a 2,194-square-foot home in Roswell, Georgia, to the performance criteria of the U.S. DOE Zero Energy Ready Home (ZERH) program.
    • High-performance features and a 6.3-kW solar electric generation system help the home cut energy costs by almost $1,900 per year compared to a similar-sized home built to code.
    • Large overhangs protect south-facing slider doors to minimize unwanted summer solar heat gain.
    • The home's white metal roof reflects sunlight, reducing solar heat gains through the roof in this hot-humid location.
    • The home's 6.3-kW solar electric system is expected to reduce energy bills to $200 a year, for monthly bills of about $17.
    • Water-saving fixtures and ENERGY STAR-rated appliances add to energy savings.
    • Natural daylight is filtered through double-paned windows with a U-value of 0.35 and a solar heat gain coefficient of 0.25, keeping warmth in during the winter and out during the summer.
    • The home's stained concrete flooring takes advantage of passive solar heating, absorbing heat from the sun during the day and releasing it into the home at night.
    • A double layer of insulation over the unvented attic helps keep the loft warm in the winter and cool in the summer.
    • Despite having several doors and windows throughout the home, the high-performance R-32 wall insulation and R-45 attic insulation helped the home achieve a Home Energy Rating System (HERS) score of 41 before photovoltaics were added to bring the score down to a HERS 6.
