This is a guest post provided by Maria Surma Manka direct from WINDPOWER 2008.  Maria writes about renewable energy policy, innovation, and private sector leadership at Maria Energia.

Greetings from Houston, site of the American Wind Energy Association’s WINDPOWER 2008 conference. I am a guest of AWEA and have spent the last few days meeting several of the 12,000 attendees and visiting many of the nearly 800 exhibitors.  Below are some of the interesting small wind turbine designs I found.

Nano Vent-Skin Demonstrated in Concept Tower

Nvs_building

I was pretty impressed by Agustin Otegui’s design for Nano Vent-Skin (NVS), rendered on the building above.  NVS is a building skin that uses organic photovoltaics to capture sun and micro-wind turbines to capture wind.  Otegui envisions nano-manufacturing with bioengineered organisms as the production method for NVS, and because it’s organic, the wall provides the additional benefit of capturing CO2 from the air. 

Obviously, the concept building above would be a new design built to reap the benefits of NVS, but Otegui also thinks the skin would be perfect for making existing buildings greener.

Kuwait's First LEED Tower To Be Crowned with Wind

Sabahalahmendifc KEO International Consultants has received word from the USGBC that its design for Sabah Al Ahmed International Finance Center (ICF) has been precertified at the Gold level under the LEED-CS green building rating system.  The 1.2 million sf, 40-story tower is the first building in Kuwait to be registered or precertified by the USGBC.  As you can partially tell from the renderings, the design includes four stacked courtyard atriums ranging from 8-13 floors each.  Three of the atriums serve the office portion of the building, while the fourth atrium serves the 200 key, 4-star business class hotel.  The tower generates part of its energy from a PV system, as well as from roof-mounted wind turbines.  You may be able to see the lattice-work of wind turbines at the crown of the building; I think they’re the vertical axis, helical-type, but it’s hard to tell with this one image.  We’ll make sure to keep you posted …

The use of wind turbines at the building’s apex is similar to what’s planned for Discovery Tower in Houston.  It’ll be interesting to see these designs meet reality — the media world will definitely have fun running video and stories of building integrated wind turbines.
