Looks like an adaptation of S/G's Clean Technology Tower- the net-zero-energy prototype with wind turbines.
Also buried in the article is that Willis will be replacing all of Sears' window panes in an energy retrofit, along with the HVAC and lighting.
Should be interesting, however it transpires.
PS - thanks much hydro.
