Energy-intensive building

General information

Located in the heart of the Innolin business park, in Mérignac, in Gironde (France), #Community is a tertiary building of 15,000 m² and brings together the Bordeaux teams of Groupama, which rents the building up to 80%.

#Community was designed to be one with nature and its environment. The building integrates many services, collaborative spaces and biophilic facilities contributing to the well-being of its users. The client was keen to bring the surrounding fauna and flora to life inside the building itself to preserve local biodiversity and offer future occupants a good well-being at work. In total, the construction includes a green roof of 2500m² and nearly 5500 m² of open ground green spaces on site.

#Community is also the first pilot operation of the Altarea Group in which reused materials have been favored over new materials. This was made possible thanks to the commitment of all the stakeholders, including the tenant Groupama, who were happy to be able to promote this approach.

Field of use and material origin :

The reused technical floor comes from the MOBIUS company in Paris.

The in-situ reuse tiling is a new tiling installed by mistake on the construction site at the level of the restaurant, carefully deposited to be reused for the changing rooms and the household waste area.

The INTERFACE brand reused carpet comes from an end of series that was no longer marketed. The carpet was present in a showroom in Paris.

The gratings being reused come from the former Groupama site at Bordeaux Lac.

Reused shower trays and sinks found thanks to the BOOSTER DU REEMPLOI Looping platform (deposited on a Parisian cleaning site).

The Circouleur recycled paint comes from a local company in Blanquefort.
