ABOUT

Passive House is the world’s leading standard for energy efficient construction. It combines building enclosure efficiency and passive solar strategies in a system for designing and building cost effective, comfortable, energy efficient buildings. The major components are:

  • Super-insulated envelope
  • Ultra-high-performance windows
  • Airtight construction (0.6 air changes /hr at 50 Pascals)
  • Eliminating or reducing thermal bridging
  • Heat-recovery ventilation
  • Using passive heat sources (solar of course, but also equipment, lighting, and occupants).

Its effectiveness has been demonstrated in projects in every climate zone around the world, ranging from single family homes to very large commercial and institutional structures. More than 20,000 examples have been completed worldwide.
