China. Shanghai. World Expo. Expo 2010 Shanghai China. Switzerland Pavilion. Micheline Calmy-Rey was elected to the Swiss Federal Council on 4 December 2002 and was appointed as head of the Federal Department of Foreign Affairs (DFA). Micheline Calmy-Rey looks out from the the Switzerland Pavilion to the Expo. The interactive, intelligent facade enveloping the swiss pavilion is a curtain of woven aluminium elements under which visitors pass to access the urban area on the ground floor of the building. LED lights comprised of an energy source, a storage unit and a consuming unit are incorporated into the facade. The energy produced is made visible in the form of flashes that are triggered by the pavilion surroundings, such as the sun or flashes made by visitor cameras. Thanks to the storage of energy in each individual cell, the facade is also active at night, when the cells will trigger each other. 27.06.10 © 2010 Didier Ruef
