Simply walking into other people’s homes? That is exactly what everyone can do during the International Passive House Open Days. Residents of Passive House buildings will open their doors to visitors during this annual open days event. They invite them to experience the high levels of comfort and energy efficiency for themselves. Welcome to Passive House! This year the International Passive House Open Days will take place from 9th to 11th November.

With a Passive House, building owners are implementing the energy transition within their own four walls. The investment costs required for the construction of a Passive House building are scarcely higher than those of a conventional building. At the same time, residents need very little energy for heating or cooling and therefore only pay a fraction of the normal heating or cooling costs. In addition, Passive House buildings can also be successfully combined with renewable energy generation.

“The recent IPCC Report from the United Nations has again demonstrated that climate protection must be consistently implemented without any further delay. As a major contributing cause of global warming, buildings must also become much more energy efficient. For over 27 years, Passive House buildings have shown that it is possible to drastically reduce the energy consumption of buildings”, explains Dr. Witta Ebel of the Passive House Institute.

Over the three days, building owners will be inviting people into their Passive Houses. A large proportion of the participating buildings are residential, including Passive House Plus and Premium buildings which produce renewable energy on-site. However, the owners of offices, hotels, church institutions, schools and kindergartens will also be inviting people to visit their Passive House buildings.
