The 310m Pearl River Tower is going to be off the electricity grid of China, in one of it’s most polluted cities, and will be run on a combination of wind turbines, solar panels and fuel cells. The building is expected to be finished in late 2010.

Other energy efficient features include a double-layer curtain-wall system to reduce heat absorption and slab concrete vaulted ceilings that enhance natural daylight. Chilled water will run through metal panels in the ceiling, helping to cool the building.

Hopefully China is finally waking up to the threat of global warming and can lead the world in sustainable building.
