Passive House standard is widely utilized in Europe, but to a much smaller extent here in the US; it achieves approximately 80% reduction in heating and cooling energy.

Passive building is designed and built in accordance with these five building-science principles:

  • Employs continuous insulation throughout its entire envelope without any thermal bridging.
  • The building envelope is extremely airtight, preventing infiltration of outside air and loss of conditioned air.
  • Employs high-performance windows (double or triple-paned windows depending on climate and building type) and doors – solar gain is managed to exploit the sun’s energy for heating purposes in the heating season and to minimize overheating during the cooling season.
  • Uses some form of balanced heat- and moisture-recovery fresh air ventilation.
  • Uses a minimal space conditioning system.
