Chosen for the tender of the EcoCité project launched in 2009, the Chengdu school group located in the “Parc Marianne” neighbourhood in Montpellier was designed by the Coste architecture agency. Built in a record time (16 months, of which 10 months for works) by Bouygues Bâtiment Sud-Est, a subsidiary of Bouygues Construction, this energy-plus building now accommodates 300 nursery- and primary-school children. The project combines energy performance and comfort thanks to its innovative, efficient equipment.
