Some additional info & renders from the SOM website. Could be wrong, but I think that Adrian Smith (of Burj Dubai fame) had a hand in this, before he left the Chicago office to start his own firm?

Pearl River Tower
Guangzhou, China
In 2005, SOM presented plans for a new headquarters tower in Guangzhou that would incorporate the latest sustainable technology and engineering know-how in an attempt to create the world’s most energy efficient high-rise structure—a tower that could significantly reduce its dependency on the city’s infrastructure. Scheduled for completion in 2010, the 71-story, 2.3-million square-foot tower will be the most energy efficient supertall tower ever built, and a milestone along the way to energy independence.
