China. Shanghai. World Expo. Expo 2010 Shanghai China. Switzerland Pavilion. View from the Switzerland Pavilion to the France Pavilion. A chinese soldier from the People's Liberation Army is wearing his summer military service uniform and is posing for a picture's portrait. Chinese are waiting hours online in order to vist the various pavilions in 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
