Wired Magazine has an article entitled Pop-Up Cities, about the plan for a large new city near Shanghai, called Dongtan:
Dongtan’s master plan — hundreds of pages of maps, schematics, and data — has almost nothing to say about architectural style. Instead, it outlines the world’s first green city, every block engineered in response to China’s environmental crisis. It’s like the source code for an urban operating system.
There is lots of info and details here about large-scale urban design within the context of being extremely environmentally friendly. A very exciting idea, and an interesting article.
