The Bahrain World Trade Center (also called Bahrain WTC or BWTC) is a 240 m (787 ft) high twin tower complex located in Manama, Bahrain. The towers were built in 2008 by the multi-national architectural firm Atkins. It is the first skyscraper in the world to integrate wind turbines into its design. The wind turbines were developed, built and installed by Danish company Norwin A/S. This 50-floor structure is constructed in close proximity to the King Faisal Highway, near popular landmarks such as the towers of BFH, NBB and Abraj Al Lulu. It currently ranks as the second tallest building in Bahrain, after the twin towers of the Bahrain Financial Harbour. The project has received several awards for sustainability, including;
- The 2006 LEAF Award for Best Use of Technology within a Large Scheme.
- The Arab Construction World for Sustainable Design Award.
The two towers are linked via three skybridges, each holding a 225kW wind turbine, totalling to 675kW of wind power production. Each of these turbines measure 29 m (95 ft) in diameter, and is aligned north, which is the direction from which air from the Persian Gulf blows in. The sail-shaped buildings on either side are designed to funnel wind through the gap to provide accelerated wind passing through the turbines. This was confirmed by wind tunnel tests, which showed that the buildings create an S-shaped flow, ensuring that any wind coming within a 45° angle to either side of the central axis will create a wind stream that remains perpendicular to the turbines. This significantly increases their potential to generate electricity.
The wind turbines are expected to provide 11% to 15% of the towers' total power consumption, or approximately 1.1 to 1.3 GWh a year. This is equivalent to providing the lighting for about 300 homes. The three turbines were turned on for the first time on 8 April 2008. They are expected to operate 50% of the time on an average day
Popular fiction — The Bahrain WTC was featured prominently in the 2009 science fiction SyFy channel made-for-television movie Annihilation Earth. In the movie, an incident involving a subatomic collider in the year 2020 creates cataclysmic effects on planet Earth. CGI is used in the movie to show the WTC collapsing as a result of an earthquake, though the reason for the earthquake is not fully explained in the movie.
