The project of the University Campus in Lyon is made up of 4units (housing, restaurants, undergraduate courses) in the city center of Lyon. The research center people's attention thanks to 2 double-skin facades. The 400 slik-sunscreen printed glass blades which compose both facades, present outstanding dimensions (53 cm width - 2.8 to 3.16 m height - average weight of 130 kg per blade).
The project aimed at finding a technical solution which :
- met the climatic and seismis constraints. - was able to maintain glass panels but also ensure the blades' rotation according to the sunshine.
Sadev designed a fixing system composed of S3000AX spiders and a mechanism which drive the blades on the lower side of the glass. This system had to provide a glass rotation up to 135°, but also glass content requirements, automated turning of the blades.
