Passivhaus Trust Newsletter - December 2025
As we close out another transformative Passivhaus year, our December newsletter looks ahead with excitement to 2026. We're set to spotlight ground breaking projects, scale up sector-wide collaboration and see you all at our FREE Passivhaus Retrofit Masterclass event! The elves are busy, the presents are stacked - sneak a peek below or enjoy the full newsletter here.
Retrofit ready for the new year.
The future of Passivhaus retrofit is bright in 2026. We’re launching new retrofit levels with PHI, publishing a fresh paper on costs, updating our guidance, and inviting PHT members to showcase projects in our Lunch + Learn Webinars - all designed to share knowledge, inspire practitioners and support high-performance retrofits.
A certified success!
Cambridge’s Hinsley Lane is now officially Passivhaus. Harking back to the traditional college setting, this thoughtful development champions an alternative ethos to the current student housing template - providing 39 new red brick terraced townhouses set within shared gardens.
Exciting New Year deals await.
Our NEW Passivhaus Retrofit Masterclass series is bursting with bargains! Join us over six expert-led sessions and earn up to 12 PHI credits. Not only is the first introductory session FREE for PHT members, you can also book the full series for an additional 20% off!
