    • Thrive Home Builders built this 3,128-square-foot multifamily project in Lone Tree, Colorado, to the high performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
    • A highly efficient building envelope and a 6.2-kW solar PV system combine to provide the owners of this townhome with energy costs savings of $2,850 per year compared to typical new construction.
    • ENERGY STAR appliances add to energy savings.
    • The ENERGY STAR double-pane, vinyl-framed windows provide an exceptional insulation value at a U-factor of 0.21. Their low solar heat gain coefficient indicates minimal heat entry from the sun.
    • A highly efficient central air-source heat pump provides heating and cooling (HSPF 9.0, SEER 15.5).
    • The efficient tankless gas water heater speeds hot water to faucets with the help of a smart hot water recirculation pump.
    • This townhome project was constructed with double walls with two 2-by-4 advanced-framed walls providing a 9.5-inch wall cavity for R-41 of blown fiberglass insulation.
    • Open corners and open headers above windows are some of the advanced framing features that reduce lumber use and leave more space in the wall for insulation.
    • The rim joists are sealed with spray foam, which helps keep out drafts, pollen, and dust.
    • At Thrive Home Builders' Building Science Center, home buyers can learn what makes a DOE Zero Energy Ready Home different from standard just-to-code new homes.

      I thought I knew what was important when it came to energy efficiency, but Thrive Home Builders went way beyond my expectations. The real test came when I moved in, got my utility bill, and all I can say is wow! The solar panels produce more energy than I am using, three months in a row so far!
