International Passive House Open Days



Are you enthusiastic about the Passive House concept and its advantages? Then take part in the Open Days and motivate others to join the movement by sharing your knowledge and experiences!


The 2023 International Passive House Open Days will take place from June 23-25 and November 10-12 and are organised for the 20th time!



Passive House Visitors:


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 first-hand 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 to 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.
