Buchner bründler architects is responsible for the concept of the Swiss pavilion which is meant to be a representation of a hybrid, interconnected urban area where nature and technology, innovation and sustainability function and interact in symbiosis, which coincide with the Chinese philosophy of Yin and Yang.
The Swiss pavilion is composed of two cylinders. The high-tech urban cylinder is equipped with 3D television screens, life-sized projections of Swiss citizens commenting on their expectations for the future and a 10-meter-tall screen depicting Swiss scenery. Upon entering the rural cylinder, visitors have the option to tour by chair lift, no doubt paying homage to the fabulous mountains in this country. The lift loops up through the building to the roof, where a field of flora provides a natural landscape in contrast to the urban setting.
The most distinguished feature of the pavilion is the outside curtain, made from degradable soybeans and dye-sensitized solar cells that are capable of generating electricity. The curtain presents an image of forest, which will remind people of the nature. And the fibre of the curtain could be degraded after being disposed in the soil in two week.
