Passivhaus Trust Activities

To meet our main aims, the Trust runs a core programme of activities:

Education & training Research & guidance Campaigns & Policy


Education and training

The Trust runs several educational events throughout the year.

The biennial Passivhaus Awards celebrate exemplars of the Passivhaus standard, while the Passivhaus Student Competition encourages the next generation of designers to gain expertise in energy-efficiency.

Conferences offer an opportunity to expand your knowledge, network and discover Passivhaus products and services. The UK Passivhaus Conference takes place towards the end of the year, and international conferences give the chance to connect with Passivhaus proponents and practitioners worldwide.

And the Passivhaus Open Days which take place twice a year, in June and November, allow the curious to experience a Passivhaus first-hand, and the knowledgeable to explore projects in detail.

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:

  • Costs and Benefits: PHT will be setting up a steering group for the new ‘Costs and Benefits’ guide which has been sponsored by Hastoe Housing Association, Saint-Gobain, Ecology Building Society, Econekt and Ashden. The steering group will also include Aecom and independent experts.

    The ‘Costs and Benefits’ guide will form two main sections. The first section will demonstrate the value to health, the local economy and wider zero carbon policies for one-off and mid-large developments, with the second section focusing on the benefits to operational and ongoing maintenance costs, whole life costing and procurement approaches and associated risks

  • Certification: The Certification group which is now part of the PHT Working Group programme includes Etude, MEAD, WARM and a member of the 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. 

Guidance documents and protocols

Via the Technical Panel meeting in January and through our internal technical team and advisers, PHT identifies areas that need further research and technical guidance documents. We are currently developing a suite of good practice technical guides which include:

  1. Large and Complex Buildings – Mark Siddall
  2. Summer Comfort – Nick Grant and Mark Siddall
  3. Insulation – Will South and Bill Butcher

In development:

  • MVHR – Sally Godber, Mich Swainson, Andrew Farr
    • Zehnder and PHT have agreed to publish guidance that covers Design, Installation, Testing and Maintenance. The guide will be written by Sally Godber, Dr Mich Swainson and Andrew Farr. The Guide is due to be published Summer 2018.
  • Airtightness – TBC
    • PHT supported by Ecology Building Systems and ATTMA have agreed to publish good practice guide on airtightness. The guide will cover the importance of planning the airtight barrier, detailing of junctions and window installation. 

All guides are peer reviewed by the PHT/iPHA technical group.


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.
