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, tour the project, and learn first-hand what it is like to live and work in a Passive House and what the building or retrofitting process is like. Some will have professionals on hand with the knowledge and tools to explain the technical details of Passive House projects.
