Choctaw Ridge

    • DP Construction built this 1,664-square-foot home in Prattville, Alabama, to the performance criteria of the DOE Zero Energy Ready Home (ZERH) program.
    • Like all DOE Zero Energy Ready homes, the home is wired for solar photovoltaic panels, but even without the panels installed, the home has utility costs of under $80 per month.
    • The home's large picture windows are double-paned with an insulating argon gas fill between the panes and low-emissivity coatings that block radiant heat to help keep the heat inside in cold weather and outside in hot weather.
    • Only LED lighting is used in this home, and the refrigerator, dishwasher, and clothes washer are all ENERGY STAR-rated appliances that save energy and water.
    • All of the home's finishes are certified as low- or no-VOC, meaning they do not emit harmful fumes into the home.
    • The home's heating and cooling needs are met by two wall-mounted mini-split heat pumps with seasonal energy efficiency ratios of 21.7. The highly efficient equipment also saves energy by eliminating ducts and the heat losses often associated with them.
    • This home uses EPA WaterSense-rated water faucets and fixtures for increased water conservation. Hot water is provided by a 50-gallon heat pump hot water heater.
    • The builder employed good water management practices (like grading the surface away from the structure, pouring on a bed of gravel, and using a vapor barrier to prevent moisture from wicking up into the walls) to help keep the uninsulated monolithic slab-on-grade foundation dry.
    • This home uses advanced framing techniques such as California corners, open headers, and single top plates to reduce the amount of lumber used and to leave more space in the walls for insulation.
    • The entire roof of the home is covered with an ice-and-water shield, which helps to protect against moisture damage.

      Home owner (or occupant) Testimony
      I like the DOE ZERH program because it is pushing the envelope and the market toward more efficient construction. The biggest reward with DOE ZERH construction is creating something that wasn’t there before that will be there for a long time for the good. We’re bringing visions and dreams to life.
