General Project Overview:

A team consisting of homeowner Keith Fusaro, Passive House Architect Louisa Bradford and builder/framer John Henderson Construction took advantage of a great location and southerly exposure when designing and building this house. This SIPS constructed house is expected to have an ACH50 around the passive house standard of .6.

Special Features:

  • SIPS
  • Triple Glazing
  • Geo-thermal loop with module tied into ERV to take the chill off or add some chill

Orientation and Envelope: (windows, insulation, framing)

  • The SIPS construction allows for an R-24 continuous insulation reducing thermal bridging and the orientation is southerly.
  • There is an additional 2x6 wall framing leaving a total exterior wall envelope of R-44. The roof also includes SIPS so the entire exposure to ambient air has a continuous thermal barrier.
  • The roof framing also allows for additional foam insulation
  • The windows, imported from Germany, are triple glazed for an average u-value of .14.

Heating, Cooling, and Hot Water:

  • The main heating and cooling source is a small 9000 BTU Mitsubishi Air Source Heat.
  • The hot water is heated by a Heat Pump Hot Water Heater.
  • The storage tank itself is in a conditioned area on the 1st floor while the separate heat pump is hanging from the basement ceiling.


  • Ultimate Air ERV


  • Fully energy efficient lighting installed throughout the home


  • Pre-wired for future solar installation
