Bouygues Immobilier did not wait for the 2012 Thermal Regulations (RT 2012) in order to forge its expertise in energy efficiency and sustainable construction. As the first property developer to systematically seek H&E (Home and Environment) certification for its residential properties and to extend BBC-effinergie®* low-energy certification to all its developments, Bouygues Immobilier is one step ahead and is already designing the positive-energy homes of the future.
Bouygues Immobilier: committed to sustainability since 2007
Bouygues Immobilier aims to build environmentally-friendly, healthy, innovative and comfortable homes. In 2007, Bouygues Immobilier became the first property developer to seek H&E (Home and Environment) certification for its residential properties. Subsequently extended to all new residential developments, H&E certification guarantees 10% better thermal performance than the regulatory requirement and greater acoustic comfort.
BBC LOW-ENERGY CERTIFICATION FOR ALL NEW BUILDINGS
Bouygues Immobilier passed a new milestone on 1 July 2010: two and a half years ahead of the 2012 Thermal Regulations (RT 2012), it committed to seeking BBC-effinergie®* low-energy certification for all its building permits. Awarded by the certification body Cergual, this label guarantees average primary energy consumption of 40 to 65 kWh/m²/year. That represents one-third of the CO2 emissions of equivalent buildings constructed in the early 2000s.
ON COURSE FOR POSITIVE-ENERGY BUILDINGS
In June 2011, Bouygues Immobilier delivered Green Office® Meudon, near Paris, the first large-scale positive-energy office building in France. Three years later, in 2014, the total surface area of Green Office® projects under construction or completed amounted to 82,750 m², 137% more than in 2012.
With its bioclimatic design and use of renewable energy sources, this cutting-edge development produces more energy than it consumes. It marks a significant step forward that has since been extended to many of Bouygues Immobilier's residential developments. Buildings like L’Avance at Montreuil, near Paris, and Vert Eden at Aix-en-Provence in southern France address both environmental and economic concerns, because the income from selling surplus energy is used to reduce building charges.
