Membership Level change

You have selected the Patron - Pre-approval membership level.

Patron membership is available to organisations actively representing, promoting and preserving the Passivhaus standard. Patron membership is subject to approval based on the following criteria.

  • Should have been standard members for at least 6 consecutive months prior application.
  • Should be fully acquainted with the definition and requirements of Passivhaus certification as defined by the Passivhaus Institute, Darmstadt
  • Should agree to support the work of PHT in protecting the integrity of the standard by promoting certification and upholding the reputation of the Passivhaus standard and methodology (See: What it means to claim Passivhaus standard in the UK)
  • Should have at least one certified Passivhaus project/product or have their service/products used in at least one certified project (this can be anywhere, i.e. not restricted to the UK)
  • Should be willing to assist with lobbying to introduce the Passivhaus standard into the mainstream building industry
  • Should not have any ongoing complaints that would bring the Trust into disrepute by association
  • Should not be part of an external investigation (criminal or other) which may jeopardize the Trust’s reputation.
