In response to the challenges of urban development, Bouygues Immobilier aims to reduce the environmental impacts of its activities and to anticipate customers' needs.
Bouygues Immobilier is continuing to make headway with its positive-energy buildings, rolling out its Green Office® concept, which anticipates the next set of energy regulations due in 2020. The company also continued to expand Rehagreen®, its commercial property rehabilitation service, which proved its appeal to customers.
In Montrouge, south of Paris, for example, Bouygues Immobilier is coordinating a green rehabilitation project for the investor La Française AM. Obsolete structures from the 1970s will be replaced by a building which will aim for HQE® Excellent certification by using borehole heat exchangers to produce energy. Handover is scheduled for late spring 2017.
A COMPREHENSIVE CARBON AUDIT
Bouygues Immobilier carried out a comprehensive carbon audit of its operations in 2014, including production and, for the first time, the operation for 40 years of residential and office buildings. The aim of the study was to obtain a full picture of buildings' carbon impact over their entire life cycle.
The most carbon-intensive aspects are user commutes during the operation phase (46% of the total carbon audit), followed by construction materials (28%) and the energy consumed by users over a 40-year period (20%). In order to reduce these three major classes of greenhouse gas emissions, workshops were organised in the company in order to define action plans which will be rolled out as from 2015.
ENERGY & CARBON AWARDS
Bouygues Immobilier swept the board at the Energy & Carbon Awards organised by the Bouygues group, claiming four of the eight prize-winning projects: Nextdoor, a concept for shared, smart and collaborative workspaces; Les Lodges, modular, environment-friendly homes; the Green Home positive-energy building in Nanterre; and Le Djinn, a timber-frame student residence which was awarded the special jury prize.
