Eco-neighbourhood development

The Bouygues group is one of France’s leading specialists in the development of eco-neighbourhoods, which are designed to combine lower consumption of resources with an improved living environment for residents. Several eco-neighbourhoods have been built or are being developed, including Ginko in Bordeaux, Hikari in Lyon and GreenCity in Zurich.


  • Energy management

Smart energy management helps to reduce the cost to residents and users of office, retail and leisure space. It is now a requirement for all eco-neighbourhood projects. Embix, a joint subsidiary of Bouygues and Alstom, is developing smart grid services to meet this need. In order to demonstrate the possibilities, a full-scale trial is under way at Issy-les-Moulineaux with the IssyGrid® neighbourhood smart grid managed by Bouygues Immobilier. Smart grids also help to smooth out energy consumption peaks and to ensure overall balance on the grid while reducing CO2 emissions. With CityBox®, Bouygues Energies & Services helps municipalities to improve the management of their street lighting networks through centralised control of lighting columns associated with new urban features such as loudspeakers and CCTV. The CityBox® is already in operation in the towns of Sèvres, Thiais, Longjumeau, Niort and Tulle.

  • Soft mobility

Better transportation is another major challenge in the management of the towns and cities of the future. Alstom, Bouygues Travaux Publics, Colas’ roads subsidiaries and Colas Rail are major players in the development of public transport (tramways and metros) and have teamed up to participate jointly in developing the necessary infrastructure for the widespread use of electric vehicles.

These innovations are the result of synergies and a cooperative approach on the part of Bouygues subsidiaries, backed up by targeted industrial partnerships.
