    *When Smith and Gill worked at SOM, I understand they
contributed to the design of Pearl River Tower, which is also an
innovative tower designed to capitalize on wind and solar
power.  We also talked about Masdar Headquarters a couple of
weeks ago, which is the world's first mixed-use positive energy
building.  Find Smith and Gill, and you'll find innovative,
green architecture.   Clean Technology Tower  Clean Technology

around it – very unlike the rendering above.    • Dan
Tetsuo makes an important point, the buildings location will
determine the wind flow characteristics. A building will need to
be designed to be site-specific in order to optimize wind
capture (i.e. maximizing mass flow rate, while minimizing
turbulent flow).      CPD modeling programs exist
