Sustainable construction

Bouygues and its business partners market low-carbon, scalable offers, beginning at the design stage and going all the way through to when buildings are up and running. These offers use traditional and bio-sourced materials that can be re-used or recycled, smart systems for optimised building management as well as renewable energy coupled with storage systems.

As a pioneer of positive energy buildings, Bouygues Immobilier is maintaining its leadership in Green Office® positive energy offices. Nearly ten years after the launch of the Green Office® positive-energy commercial property concept, some 20 Green Office® projects have been handed over, such as Prism’, the Colas headquarters building in Paris, in July 2018.

 

Prism’, the first Green Office® to be built where Bouygues was the main contractor

A product of the synergies between the Group’s subsidiaries (built by Bouygues Bâtiment Ile-de-France Construction Privée, a Bouygues Construction subsidiary, on behalf of property developer Bouygues Immobilier), Prism’ is exemplary in terms of energy performance. It has been awarded three environmental certifications: Bepos-Effinergie 2013, HQETM Exceptionnel millésime 2015 and BREEAM® International 2013, Excellent. Thanks to 540 m2 of photovoltaic roof panels and a cogeneration plant fuelled by rapeseed oil, the building produces more renewable energy than it consumes.

BBCA: a driver of ecological transition

Bouygues Bâtiment Ile-de-France and Bouygues Immobilier are members of the BBCA (the Low-Carbon Building Association) and have helped launch a label of the same name by submitting projects for certification. The label is used to publicise actions aiming to reduce the carbon footprints of buildings across their entire lifecycle.

The Green Office® Enjoy positive energy office building (Bouygues Immobilier), located at the heart of the Clichy-Batignolles mixed development zone, is the biggest positive energy commercial property with the BBCA low-carbon building label in France.

ELSA: an energy storage system

Bouygues Energies & Services is part of the European research consortium working on the ELSA [1] project. ELSA recovers used batteries from electric vehicles and re-uses them in buildings to create energy-storage systems. Six pilot sites have been set up around Europe to illustrate six different scenarios.
