The Hikari Project (Light in Japanese) remains to be the first energy (EBP) positive building in France, combining offices, shops and housing. This EBP building is located in the new "Lyon Smart Community" area, Confluence.Designed by the Japanese Architect Kengo Kuma and realized by Bouygues immobilier, this 12 800 m² block is made up of 3 buildings.
A tedious but environmentally oriented work helped to develop buildings that benefit either for the highest natural lighning, or reduce noise disturbance.
The architects preferred gigh dimensions' glass openings to emphasize the lightning. Thanks to the produced energy storage and pooling, Hikari is capable of supplying its own energy for the 3 blocks. Photovoltaic panels are located on the MINAMI's building south facade, in order to benefit from the seasonal light energy.
For this building, Sadev provided nearly 1 500 rotules to maintain the photovoltaic panels. As the project required an installation from the outside,the R1008 were chosen to simplify the mounting & respect the French railing legislation.
