PROJECT DESCRIPTION
The architect designed the building in the form of a slim prism that integrates the emergency exit from the cinema rooms. This totem with a varying square cross section and a height of 30 m has a translucent backlit exterior skin. This gives the image of a large lamp lit with a range of colours thanks to the system of RGB LEDs. The lower part of the totem ends with a stainless steel mesh. The cover is a translucent matte ETFE membrane on the exterior, an air chamber containing the lights and a white PES/PVC membrane on the inside. This last textile reflects the light to the outside. A structure 13.6 m high with the same façade type was also built on the corner of the annexed building.
TECHNICAL BASE
Construction of façades with ETFE membranes, using IASO’s single-layer system reinforced with cables. Each façade consists of a single membrane made from matte ETFE sheets (250 µm thick) from the brand ASAHI, reinforced with metal cables spaced every 700 mm. Behind these matte ETFE membranes, a white opaque PVC membrane (PRECONTRAINT 702 S2 from Serge FERRARI) is installed at a distance of 586 mm. In the air chamber between the two membranes, LED lights are installed at a distance of 273 mm from the ETFE membrane.
The PVC membranes are fixed to the metal structure of the totem using a spring system and equipped with a peripheral gasket.
The cables are spiral-type, made of AISI 316 stainless steel, 8 mm in diameter, and anchored to the metal structure at both ends. On one side, they are tensioned using a threaded rod system. The cables are inserted into the membrane sleeves. Edge waterproofing is achieved with 1.5 mm thick metal plates fixed to the totem corners. These profiles are made of silver anodised aluminium.
