This climbing gym is like no other in the world. The exterior looks like a piece of crumpled tin foil, but when night falls, the crumpled building becomes transparent, with the climbers inside on view for all to see.

Watch the transformation:

Hope it's in a warm region of the world. It seems quite uninsulated.
+Mads Thomsen  vacuum is the best insulation, low pressured gas is almost as good. What you don't see insulates best.
I would be interested in the thermodynamics of the building. He says "hermetic" but if holes in the aluminum are the only thing creating the transparency, then it doesn't sound hermetic unless there is another layer. Still a beautiful building, and an ingenious design. Though it doesn't seem particularly cost effective to create an entire exterior out of custom shaped aluminum.
