Advanced Building Skins
Special attention was paid to control the deflections of the whole façade as well as the warping of the
most critical insulated glass units by optimizing every single cable pretension force. These vary from
80 to 330 kN. Black coated curved aluminum shading devices further characterize the façade design
and mitigate the museums heat gain.

The cable clamp and glass fixing has been designed specifically for this museum with the aim of reducing
the material to a minimum and to match the specific architectural language. The 3D-Model for
the pieces has been precisely defined in collaboration with a small casting factory specialized in Italian
design objects.
3 Aluminium Roof
The 77 m long and 43 m wide freeform aluminum roof has to withstand wind, rain and snow while
still being able to freely deform due to temperature variations and the absence of any expansion joints.
A sophisticated detailing which allows for controlled movements and a parametric approach were the
keys to address this task.
