Hickory Ridge

    • Greenhill Contracting built this 3,912-square-foot custom home in Gardiner, New York, to the high performance criteria of the U.S. Department of Energy Zero Energy Ready Home (ZERH) program.
    • The 10.26-kW PV system and highly insulated structure help the home perform as a net zero home that produces as much energy as it uses in a year.
    • The lack of pipes, flues, and vents coming out of this roof is a good thing. It means less holes where heat can leak out and water can leak in.
    • A daylight basement and insulated attic mean three floors of living space plus storage in the compact structure.
    • No-/low-VOC paints and finishes and an energy recovery ventilator fresh air system that continually draws in filtered fresh air help ensure clean air inside the home.
    • The basement slab is wrapped in a blanket of insulation including R-27 of closed-cell spray foam under the slab and R-22 ICF blocks wrapping the slab edges.
    • Wiring runs are covered with canned spray foam to maintain the continuous foam layer that covers the inside and outside of the ICF block walls.
    • Seams in the ICF block are sealed so the EPS foam surface can serve as the drainage plane; no house wrap is needed.
    • Before installing the triple-pane vinyl framed windows, the window rough openings are sealed with a liquid-applied flashing that provides a seamless moisture and air barrier to protect the wall from moisture intrusion.
    • The attics are insulated to R-64 with a hybrid application of 11 inches of open-cell spray foam (R-4.45/in) plus 2 inches of closed-cell spray foam (R-7.4/in) that completely fills the roof rafter cavities and encases the rafters creating a continuous blanket of insulation across the attic ceiling.

      Greenhill Contracting has been 100% committed to building DOE Zero-Energy Homes since 2007. The team has worked tirelessly to reduce the construction costs associated with high-performance homes including developing continuous improvement strategies. At this point, with the use of ICF and spray foam thermal and air-control strategies, the DOE Zero Energy Ready threshold can be achieved without any significant costs over a code-built home.
