The Courtyards

    • High Performance Homes built this 6,000-square-foot home in Gettysburg, Pennsylvania, to the performance criteria of the U.S. DOE Zero Energy Ready Home (ZERH) program.
    • The energy- and water-saving measures incorporated in this home are estimated to save $1,600 per year, not counting the home's solar electric generation system. The average monthly energy bill will be about $100.
    • The solar electric panels on this home look similar to traditional roof shingles but provide 7 kW of solar power. They are projected to boost the annual energy savings to $2,500 per year and $109,000 over a 30-year mortgage.
    • The home is oriented to maximize warmth and light from the sun in winter, but windows are shaded by eaves to reduce excess sunlight in summer.
    • The hip roof design adds hurricane resistance, while the ENERGY STAR-rated reflective shingles minimize heat gain to the attic, which is insulated with a combination of blown-in insulation and closed-cell spray foam that provides an insulation value of 53.
    • The home's daylight-basement is insulated with 2 inches (R-10) of rigid foam under the slab, while a half-inch of rigid EPS separates the concrete foundation walls from the interior stud-framed walls, which are filled with R-15 of batt insulation. The downstairs daylight walls, like the above-grade walls, are made of R-37 structural insulated panels (SIPs), which connect with the other foam layers to form a continual thermal blanket around the home.
    • Durable materials like composite decking, lifetime guaranteed roofing, and stone cladding plus sturdy SIP walls add to the storm resistance of the home.
    • Site grading, pervious pavers, drywells, and the site's own natural topography are taken into account to minimize storm water runoff.
    • Wide doorways and level entries are among the aging-in-place features that make this high-performance home a more accessible one, as well.
    • The high-efficiency windows are double-paned, have argon gas fill between the panes to increase their insulating value, and are coated with invisible low-emissivity coatings that help to reduce heat gains and losses.
