Pronghorn Ranch

    • Since building their first U.S. DOE Zero Energy Ready Homes in Phoenix in 2013, Mandalay Homes now certifies all of its homes to DOE Zero Energy Ready, ENERGY STAR, Indoor airPLUS, and WaterSense, including this high-performance home in Prescott Valley, Arizona.
    • The owners of this home will save nearly $2,000 each year in energy costs compared to the owners of a new home the same size that just meets code.
    • High-efficiency ENERGY STAR appliances, advanced solid-state lighting technology, and water-conserving WaterSense plumbing fixtures contribute to energy and water savings.
    • Sales office displays help buyers compare Mandalay Homes' energy-saving features and construction details with standard construction homes.
    • The home features high-efficiency endless hot water with a 95% efficient gas tankless water heater.
    • A professionally installed balanced fresh air system removes stale air while bringing in fresh filtered air, including advanced technology to exchange heat and moisture for energy savings and enhanced comfort.
    • The ultra-efficient triple-pane windows are manufactured with special invisible reflective coatings to keep out heat in hot weather while letting in plenty of daylight.
    • Premium installed spray foam insulation fills the walls and covers the underside of the roof deck to provide enhanced quiet and comfort to the living space while protecting the HVAC ducts from extreme heat and cold.
    • The continuous thermal blanket wall construction uses 3.5 inches of open-cell spray foam in the framed cavity along with an inch of rigid foam wrapped around the exterior sheathing.
    • The professionally installed comfort delivery system includes right-sized ducts that are air-sealed, insulated, and located completely inside the conditioned space. These ducts will be protected from extreme temperatures that occur in attics during hot Phoenix weather.

      "The energy efficiency of my home has truly blown me away. One power bill totaled $3.64 and another totaled $7.96. As far as I’m concerned, you can’t beat that." – Homeowner Marsena

      Testimonials

      Home owner (or occupant) Testimony
      We’ve been in the house for about two months now, and we’ve found the house to be very comfortable and energy-efficient. It’s late June in Arizona and the house is so well-insulated that despite peak temperatures in the mid-90s outside, we have yet to turn on the air conditioning and the house has maintained an inside temperature between 78 and 82 degrees.
