Passivhaus Trust Newsletter July 2026
This month, we're exploring the evidence behind some of the sector's most common questions. How much does Passivhaus really cost? Can it keep buildings comfortable during extreme heat? Is Passivhaus retrofit achievable? And what can award-winning projects teach us about delivering better buildings?
Dive in below, or head to the full newsletter for the complete roundup
How do you deliver buildings that actually perform?
Designing a building is one thing. Delivering the performance promised on paper is another.
As overheating, rising energy costs and stricter expectations reshape the built environment, the projects that succeed are those that close the gap between design intent and real-world outcomes.
At the UK Passivhaus Conference 2026, industry leaders will share the lessons, challenges and practical approaches that are helping teams deliver buildings that perform as intended. Join us and earn up to 21 PHI credit points in 48 hours.
Is Passivhaus really more expensive?
For many clients and project teams, cost is still the biggest question.
But what happens when you look beyond assumptions and compare the evidence?
Our latest research examines published capital cost modelling to assess the cost uplift of building to Passivhaus, alongside the longer-term value created through lower running costs, greater resilience and more reliable performance. The findings may surprise you.
What does award-winning design have in common?
This summer has been a landmark one for Passivhaus projects, with recognition across some of the UK's most respected industry awards.
From housing to public buildings, these projects demonstrate what's possible when performance, quality and good design come together.
See which projects were recognised and what made them stand out.
What happens when the heatwave arrives?
This summer's extreme temperatures weren't a future scenario, they were a real-world test.
As schools closed and overheating dominated headlines, Passivhaus buildings offered an opportunity to see how high-performance design responds under pressure.
Read what visitors experienced during the Passivhaus Open Days and discover the practical strategies helping buildings stay comfortable in hotter summers.
What does it take to bring Passivhaus into the mainstream?
Making high-performance buildings the norm requires more than good design, it requires shared knowledge across the industry.
This autumn, the Passivhaus Trust and CIOB are launching a new three-part webinar series, combining technical knowledge with practical construction insight. Designed to bridge the gap between Passivhaus design and real-world delivery, the partnership opens up new training opportunities for professionals across the built environment.
Discover what the partnership means for your professional development and how you can get involved.
