Recently, in the Week in Review, I blogged about these twin skyscrapers becoming the world’s first commercial development to include large-scale wind turbines in its structure. As you can see from the pictures, Bahrain WTC towers have three, 32-yard diameter propellers that supply about 11-15 % of the buildings’ energy needs, or about 1100 to 1300 megawatts per year. The shape of the towers create an airflow tunnel through the buildings for improved energy generation output and each turbine will be suspended on a bridge connecting the buildings. According to BWTC designer Shaun Killa, solar panels available at the time of construction lost their efficiency due to the high Bahrain temperatures, so wind technology was the better choice for renewable supply. The turbines will be tested throughout the year and the building will open for business later in 2007.
The dueling towers are 50 stories each, with 34 floors of office space. When complete, the entire complex will include a shopping mall, including about 150-200 luxury brand retail sites, and a 5-star Sheraton hotel. In addition to having SMART features that include high-tech security and IT infrastructure, the building will use an environmentally friendly water cooling system. Via GE Eco-Business.
