Solar and wind in a Chinese skyscraper:  A leading US architecture firm, Skidmore, Owings & Merrill (SOM) "has designed a 69-story building for China that will produce more energy than it consumes. [SOM] is among three finalists in an international design competition for a building in Guangzhou, a port city of 6.6 million people located 182 km from Hong Kong. ..

The design directs and manages prevailing winds to become ‘invisible braces’ which help to support the tower. The sculpted facade directs wind to a pair of openings on the mechanical floors, which then drive turbines to generate electricity for the building's heating, ventilation and air conditioning systems.  “The openings also relieve wind pressure on the face of the building,” explains project architect Gordon Gill of SOM. “Potentially-damaging negative pressure on the opposite side of the building is alleviated as well. The result is a more stable, more comfortable building.”

Energy consumption is reduced by maximizing natural day-lighting, reducing solar gain in air conditioned spaces, retaining rainwater for gray-water usage and using solar thermal collectors to heat the water supply. Stack venting, radiant slab cooling and caisson heat sinks work to chill the building, and building-integrated solar panels on the facade generate AC power... The winner of the design competition is expected to be announced in February."  9:50:14 AM  permalink
