In 2012, Saint-Gobain created one of Belgium’s first Passive Houses in the forested mountains of the country.

On the heights of the Ardennes region, Saint-Gobain and the architectural studio A33 worked together to develop a passive habitat project called Passive Live.

This MULTICOMFORT house provides a very high level of comfort, while consuming virtually zero energy – even in extremely variable climatic conditions. It is now available for rent as a holiday home, giving people the opportunity to experience life in a passive house.

Highlights and challenges

A primary objective of this MULTICOMFORT project was to encourage people to think about energy use in their own homes – through experiencing all the benefits of one of Belgium’s first Passive Houses, which is now available to rent as a holiday home.
