Research and guidance

The Passivhaus Trust organises a Technical Panel of industry experts to participate with ongoing working groups. The key aim of the technical working groups is to investigate detailed aspects of applying Passivhaus in the UK. The findings from these working groups will result in a series of technical & introductory guidance notes, aiming to ensure the integrity and success of Passivhaus buildings in the UK. Several introductory guides are available for Passivhaus beginners as a free download. Technical information can be found in our guidance and knowledge base sections.

Working groups

Current technical working group topics include:

  • Air Pressure testing standard: ATTMA and PHT are working together to redefine ATTMAs TSL1 testing standard to incorporate the Passivhaus methodology. The project will also form a basis for new accredited training course with recognition for registered air pressure testers that have completed the training on ATTMAS website.

  • Certification: The Certification group which is now part of the PHT Working Group programme includes Cocreate, MEAD, WARM and a member of PHI certification team. The aim of this group is to discuss arising issues and inform the PHT board and other working groups on potential research opportunities. 

  • In-use performance: The In-use Performance working group is initially targeting 20+ sites that will be compared, similar to the CEPHEUS research project. A key output from this group will be UK-centric graphs plus data that can be used and referenced. The research team includes WARM and Bath University.

Guidance documents and protocols

  • Certification: The UK certifiers Cocreate, MEAD, WARM are due to author guidance on the process of certification, with a user-friendly explanation of the new standards and classifications now available to clients and designers.

  • MVHR: Zehnder and PHT have agreed to publish guidance that covers Design, Installation, Testing and Maintenance. The guide will be written by Sally Godber and Mich Swainson

  • Insulation Continuity: Knauf, Saint-Gobain and Kingspan are supporting PHT to author a good practice guide on the importance of Insulation Continuity. The guide will cover Design, Procurement, On-Site storage and Installation and will be written by Will South and Bill Butcher.


Campaigns and policy

As well as providing the advice and support described above, the Passivhaus Trust works to promote uptake of Passivhaus in the UK. This may be based on informal engagement with Government organisations and their consultation processes, but will also involve more active promotion of the Passivhaus standard, particularly:

  • Investigating integration of the Passivhaus standard with UK national and local policy
  • Producing guidance and tools tailored for different Passivhaus audiences
  • Ensuring quality of buildings claiming Passivhaus standards in the UK

In addition, the Trust will work with partners to promote Passivhaus more generally, including to planners, clients, local authorities, architects, engineers, housing associations and others. Passivhaus goes Personal is an ongoing campaign aimed at the custom & self-build market and in 2017 we will be launching a campaign aimed at Local Authorities briefly mentioned above. Visit our campaigns and policy section for more details on other recent schemes.
