Comfort from every angle

The Multi Comfort concept is designed to deliver every kind of comfort, in any kind of building, anywhere in the world. And always in a sustainable and economical way.

Thermal Comfort

Multi Comfort buildings keep themselves at an optimal temperature using very little energy. They’re neither too hot nor too cold – so we can function comfortably, whatever we’re doing.

Visual Comfort

Multi Comfort buildings bring the outdoors in. They maximize daylight to create the right amount of light for specific tasks – whether it’s reading, performing surgery or working out at the gym.

Acoustic Comfort

Multi Comfort buildings have well-balanced sound environments. They actively protect us from unwanted exterior noise, and enhance those sounds that we do want to hear.

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.
