Each year the International Passive House Association invites Passive House buildings around the world to open their doors for a weekend. These are the open houses and events in North America: visit a building, meet the people who designed, built, and live or work in it, and see how they did it. For buildings elsewhere, see iPHA’s Open Days page.
November 13–15, 2026
More listings coming soon.
Host an open house
Any building designed and built with the Passive House method, with a completed PHPP energy balance, can take part: certified or not, finished or under construction. Pick a time over the weekend, tell your project’s story, and keep attendance free. Fill out the host form and we’ll list it here.
