June 25-27

The International Passive House Open Days are a great opportunity to learn about Passive House buildings of all kinds, around the US and the world. Get in contact with current owners and learn first-hand what it is like to live and work in a Passive House and what the building or retrofitting process was like. Some will have professionals on hand with the knowledge and tools to explain the technical details of Passive House projects.

  • Find participating Passive House buildings in the Passive House Database. Viewing and/or event information is included in the entry!
  • Take a digital tour! Digital content for the Mid-Year International Passive House Open Days will unlock on the International Passive House Association’s Youtube channel at 6 PM ET Friday, 25 June 2021. For now, you can discover digital tours from last year’s #iPHOpenDays in the dedicated YouTube playlist on the same channel.
  • Finding a local project via the Passive House world map! All the new participating buildings are marked in yellow, whereas the buildings that took part also in previous editions are marked in blue.
