North Star Plan

    • Philgreen Construction built this 1,770-square-foot home in Fort Collins, Colorado, to the performance criteria of the DOE Zero Energy Ready Home (ZERH) program.
    • This home's 8.56-kW solar electric system and energy-efficient construction give it a Home Energy Rating System (HERS) score of -9, meaning the home will produce more energy than it consumes, saving its homeowners $2,070 a year in energy costs compared to a standard new home built to code, which would have a HERS of roughly 80 to 100.
    • Two ENERGY STAR-rated ceiling fans are installed to help the home feel comfortable while using less air conditioning.
    • Low-VOC paints, finishes, and cabinets help this home earn a EPA Indoor airPLUS certification.
    • For additional energy savings, nearly all of this home's lighting is supplied by advanced technology LEDs.
    • An ENERGY STAR-rated refrigerator, dishwasher, clothes washer, and dryer are installed to reduce energy and water use.
    • The home's advanced comfort system includes a ground source heat pump that provides energy-efficient heating and cooling.
    • In the home's bathrooms, dual-flush toilets and EPA WaterSense-rated plumbing are installed to conserve water.
    • To reduce heat loss through the windows, this home has energy-efficient double-paned windows.
    • This home's solar electric system generates more than $2,000 per year for the homeowner.

      Testimonials

      Home owner (or occupant) Testimony
      I’m really pleased by the renewable energy and the performance of this home. My energy bills including transportation [for an electric car] were … $5 [in winter] and now have gone negative in the spring and will continue to earn money in the summer. I won’t have to worry about increasing energy bills in the future because I am more in control of both my energy use and production.
