Herzog & de Meuron, 2005
Football stadium with 69,901 seating capacity. The photograph shows its facade made up of inflated ETFE panels. The panels when viewed from a distance seem white, but in fact their surface is a combination of the translucent ETFE foil populated with many small white dots. The foil has a thickness of 0.2 mm.
GSW Headquarters, Berlin
Sauerbruch Hutton, 1999
The GSW tower was the first tall building to rise in Berlin after the fall of the wall. The building structure follows a classic order of base (podium), body (a very thin and curved slab) and crown. Because of the separation between podium and tower, the building is able to integrate itself and respond to the complex urban situations created by the disappearance of the Berlin Wall.
The extreme thinness of the building body, I suppose, results from the incorporation of passive strategies for sun screening and cross ventilation of air flows. The polychromatic facade is constantly changing depending on the users adjustments of the operable windows.
