The International Passive House Open Days are a great opportunity to learn about Passive House and energy efficient buildings. Get in contact with current owners and learn firsthand what it is like to live in a Passive House and what the building or retrofitting process was like. Some open houses and buildings will even have professionals on hand with the knowledge and tools to explain the technical details of Passive House projects.


As well as all the opportunities to talk and learn about Passive House, participants can experience Passive House buildings, both residential and non-residential, for themselves. Enjoy the comfortable interior temperatures, take a look at the ventilation system, ask questions and consider the possibilities of Passive House for your own building projects.
