Better buildings already exist. Step inside next week

From 22–28 June, more than 25 pioneering Passivhaus projects across the UK will open their doors for the 2026 Summer Passivhaus Open Days, part of London Climate Action Week. This is your chance to experience first-hand how the Passivhaus standard is delivering healthy, comfortable, resilient and ultra‑low‑energy places to live, work and learn.

Across the country, visitors will be welcomed into new-build Passivhaus selfbuild homes, EnerPHit retrofits, commerical offices, social housing schemes, and leisure facilities. Whether you’re curious about the design process, planning your own project, or working in the built environment, these tours offer a rare opportunity to see high‑performance buildings in action.

You’ll find everything from rural self-builds and Passivhaus Premium homes to ambitious retrofit transformations that show what’s possible for the UK’s existing building stock.
