Second place went to a French architecture team from OH!SOM architects who proposed a pavilion composed of a series of floating balloons. The balloons serve multiple purposes by broadcasting the games, generating solar power for night lighting, cleaning the air of CO2, and providing shade. The project also sought to address the use of recycled materials and recycling trash from the games.
Third place was won by a US team from Dowling Duncan whose pavilion is an oragami version of a track. Made from ground up recycled running shoes, the track provides an interactive place to play and gather. The track and the building below it are oriented to maximize daylighting and natural ventilation from air-cooled by the fountains. Unfortunately, as great as these ideas are, the competition was purely for conceptual designs and the projects will not actually be built. The competition sought to “encourage and reward design excellence at a small-scale which integrates function, structure, details and the spirit of the games, as well as encourage the employment of sustainable design in all aspects of the proposal.”
