London : zero-carbon buildings

The City of London is building two carbon-neutral buildings as its contribution for the Shanghai World Expo’s Urban Best Practices Area. The buildings will house a lecture hall, a restaurant, an exhibition hall and six model rooms. The inspiration for London’s UBPA Pavilion came from the Beddington Zero Energy Development (BedZED), an environmentally friendly housing development near Wallington, in the London Borough of Sutton.

The two three-story houses on the Puxi side of the Expo site will cover a total area of 2,500 square meters. They will have slanted rooftops covered with plants and solar panels. Eleven windmills on each of the rooftops will bring fresh air into the houses. Restaurant leftovers will be used for power generation. Visitors will be able to see the process of how the leftovers are turned into electricity.
