The structure called "Surface of the wall windmill ecological curtain" is made of 775 vertical windmills and is expected to produce 7,551 kilowatt-hours annually. Combined with solar panels set on the top of the structure, the energy collected will be used to power lighting in the mall building.
Doesn't seem like a very good deal as far as power-generation vs. surface ratio is concerned. They'd probably get more from a single regular wind-turbine on the roof of the building.
Maybe their concern was noise? There's probably a way around that even with a regular wind-mill, though (although you'd probably lose efficiency).
I think the point is integrating design and color with some small degree of clean power generation.
