RFR participated in the design studies of the facades in collaboration with the architectural office.
- The vertical glass louvers covering all sun-exposed façades, positioned to optimize shading while not obstructing the view.
- The main facades, located to the south-west and north-west, are double-skinned glazed facades, naturally ventilated from the outside to create a transparent and bright facade while providing enough shading.
- The secondary facades, located to the southeast and northeast, alternate between opaque and glazed polished aluminum surfaces, which reflect the overall geometry of the tilted glass louvers.
The design allowed this building, located within the new EuraTechnologies economic hub, in Lille, to be a low-consumption building, running mostly without air conditioning whilst maintaining thermal comfort even in the summer.
