For this project, safety-laminated glass modules with an air gap were chosen; these improve the thermal and acoustic insulation of the building and generate a total of 2,500 kWh per year, preventing the release of 1.6 tons of CO2 into the atmosphere. The energy generated enables the powering of 141 lights for the 4 hours per day required by the client.
The glass modules measure 2,954 x 1,240 mm (9.69 x 4.07 Ft) and feature a degree of transparency of 10%. The glass has a Solar (g) Factor of between 5% and 40%, and is capable of filtering out 99% of ultraviolet radiation and 95% of infrared radiation, making it an optimal choice in the prevention of overheating of the building and thus enhancing the thermal comfort of its occupants.
The refurbishment of the building was managed by the town planning authority of the city, the Bordeaux Métropole Aménagement (BMA), and was designed by the architect Jean Louis Montagnier.
