As many countries prepare for World Expo 2010 in Shanghai, the proposed design for the Shanghai Corporate Pavilion is attracting a lot of interest. This beautiful building will be made from plastic tubes created from recycled CD cases. The design includes a plan to recycle the tubes again at the end of the building’s life. Computer-controlled LED lights installed on the outside of the structure will allow multi-color lights to play across its surface. While in use, the building will use sustainable power provided by a solar thermal energy system consisting of heat-collecting tubes on the roof that provide power to heat water and generate electricity in the building.
