Paris succeeded because the project, inaugurated almost a year ago, is one of the first commercial buildings of this type and size (17000m² SDP) certified PassivHaus.
For the façade, the request related to a VEC aspect with a 20 mm joint between glazings, alternations of concave straight and curved straight and convex façades in continuity, and a UCW objective of 0.8 W / m².K.
To do this, the architect Artefact, planned to use triple glazing which also makes railing, with glazing layout up to L.1.5 x H.4.11 m. for a weight up to 500 kg. The curtain wall solution with clamming glazing appeared the most relevant, in this case the Reynaers Aluminium CW 60-SC system. It has been adapted with specific creations, including pieces of glazing supports depending on the different façade curves to be connected, integration profiles, fire and fire escape frames (TS 68).
Implemented by the company Coveris with Ava, this system except DTI33.1 required an Atex procedure with AEV tests and impact resistance tests for the railing.
