  • “Large consumer” energy audit of the campus (including ULB laboratories and datacenters)

Since 2016, through various study and consultancy assignments subject to public contracts, we have been assisting the Université Libre de Bruxelles in their technical and energy management. In concrete terms, this first resulted in a “big consumer” energy audit imposed as part of the extension of the site's environmental permit. This audit made it possible to put in place an action plan supporting the university's longer-term strategy. The collaboration then continued with the design office mission for the renovation of 4 substations (buildings A, C, E1, E2) as well as the techniques of building S.
