International Passive House Open Days
November 5-7, 2021

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! Information to follow. 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.

Do you have a Passive House building you’d like to share? The criteria for joining the event are simple – just answer “yes” to these questions:  Was it designed and built with the Passive House methodology?  Did you complete the Passive House Planning Package (PHPP) energy model for the design and construction? Are you willing to tell your Passive House story?  

If the answer is yes to those three questions – we hope you register and share your building.  Find out more information about hosting, submitting your building, and giving a tour!

Featured American Projects: Nov 5-7
