The Bahrain World Trade Center is a 240-metre-high (787 ft), 50-floor, twin tower complex located in Manama, Bahrain. The towers were built in 2008 and are the first skyscraper in the world to integrate wind turbines into its design.
The two towers are linked via three skybridges, each holding a 225kW wind turbine, totalling to 675 kW of wind power capacity. 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.
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.
