This heat exchanger - riothermal system- can be used to heat buildings in winter but also to provide air conditioning in summer.

This patented system is currently being installed as part of the renovation of a 15,000 m² communal building in Uccle's Brussels neighbourhood. It will contribute to the sustainable transformation of Brussels' municipalities, as it will make use of untapped resources present in the urban landscape.

The project was selected for the Publica Awards 2020 in the category 'Urban Development, Infrastructure & Mobility'. The results will be published next December.
