Organized globally by the International Passive House Association, 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.

Our basic guidelines:

  • Dates, times and duration of open house, over the three days, is/are, at the discretion of the owners.
  • The project can be under construction.
  • Certification is not required, but a plus.
  • A calculated PHPP is required.
  • Tours led by someone willing to tell the story of the work (owner, architect, builder, consultant etc…) and speak to the process, systems and components, to their best ability.
  • Provide dates, times, and location of open house, with pictures and basic description, to PHN for publicity.
  • Preferably hosts set up an Eventbrite to track registrations.
  • Attendance should be free.
