Passivhaus home standards

Passivhaus is a collection of standards, originating in Germany, for home insulation, draughtproofing and so on. These collectively result in very little energy being needed to keep homes warm enough to be habitable.

The key components are
  • Excellent insulation with elimination of all thermal bridges
  • Extreme draughtproofing
  • Blown air ventilation and (occasionally) heating
  • Heat recovery from the air that is being expelled to warm incoming air.

Example social housing scheme
Norwich Council has built 100 homes to Passivhaus standards - see https://www.theguardian.com/artanddesign/2019/jul/16/norwich-goldsmith-street-social-housing-green-design.
