Smith+Gill have in their portfolio section of their website a project called Clean Technology Tower. (See the facade section at left.) This "mixed use" tower in Chicago is an evolution of the Pearl River Tower which both Adrian Smith and Gordon Gill were responsible for while at SOM. Where Pearl River used the face of the building to funnel wind into two large turbine zones this design uses an array of smaller turbines at the corners of the building to catch the wind at its highest velocity. It would be very exciting to see this project take shape, as both the form of the building and the technology involved are very engaging. It is equally interesting to see them continuing to push the limits of net zero building technology after leaving SOM. By looking at their internal roster it's clear that Smith+Gill have enlisted some of the finest talent.
