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.

Selsam Small Turbines – Just Right for Residential?

Selsam

The bloggers at Engadget picked up on the Selsam small wind turbines, which look a lot like one of those amateur ham radio antennas we used to see on houses.  This small-scale wind solution is basically a single elongated shaft made of strong carbon fiber.  The carbon shaft holds rotors that range in size from 14-18 inches in diameter.  Apparently, the more rotors you have on a rod, the better output you get.  Invented by Doug Selsam, this 13-rotor small wind turbine can produce roughly 200 watts in 20 mph winds (or more in higher wind speeds).  It’s currently being tested and developed in California, so who knows, we may just start seeing stuff like this on top of houses and buildings?

Wind Could Power 20% of US Grid by 2030

Palm Springs Wind Farm

Here’s some interesting news: a new Department of Energy report claims wind turbines could generate 300 gigawatts of electricity — roughly 20% of the US electrical grid — by 2030.  There’s already a website in support of the news at 20%Wind.org.  The report doesn’t necessarily predict the future of the wind industry, but it paints a picture of what a particular 20% wind scenario could mean for the nation.  The wind industry currently produces about 17 gigawatts of electricity, so we’re talking about significant growth over the next twenty-something years.  That said, wind industry growth has been fierce in recent years and is on track to meet these numbers if growth holds pace.

OptiSolar Planning Largest PV Solar Farm in World!

Optisolar Topaz Solar Farm This is big news for the green building revolution, because a solar farm like this could power roughly 190k homes in California.  Referred to as the Topaz Solar Farm, this $1 billion, 550-megawatt plant would cover roughly 9.5 square miles, and if constructed, would be the world’s largest photovoltaic solar farm.  Hayward-based OptiSolar is developing plans for the project as we speak.  According to their current time line, OptiSolar will apply for a conditional use permit in May 2008 and begin construction in 2010.  Topaz Solar Farm would then be completed over three years.

[Video] BedZED Zero Energy Homes

You've probably already heard of BedZED, but have you seen it?  Feel free to watch a short little video about the cutting-edge community. 

BedZED is a 100-home, sustainable community in Beddington (UK) that's designed to be a Zero Energy Development.  Hence the Bed and the ZED. 

The colorful wind-driven ventilation system gives it a quirky, kind of playful look — but don't be fooled: This joint is all business.  Most of all, residents appear to enjoy the sense of community and quality of life.
