The Bahrain World Trade Center (also called Bahrain WTC or BWTC) is a 240 m (787 ft) high twin towercomplex 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.This 50-floor structure is constructed in close proximity to the King Faisal Highway, near popular landmarks such asthe towers of BFH, NBB, Abraj Al Lulu and the scenic Pearl Roundabout. It currently ranks as the second tallestbuilding in Bahrain, after the twin towers of the Bahrain Financial Harbour. The project has received several awardsfor sustainability, including;1. The 2006 LEAF Award for Best Use of Technology within a Large Scheme.2. The Arab Construction World for Sustainable Design Award.[2]

Structural details

The BWTC under construction.

The two towers are linked via three skybridges, each holding a 225KW windturbine, totalling to 675kW of wind power production. Each of these turbinesmeasure 29 m (95 ft) in diameter, and is aligned north, which is the directionfrom which air from the Persian Gulf blows in. The sail-shaped buildings oneither side are designed to funnel wind through the gap to provide acceleratedwind passing through the turbines. This was confirmed by wind tunnel tests,which showed that the buildings create an S-shaped flow, ensuring that any windcoming within a 45° angle to either side of the central axis will create a windstream that remains perpendicular to the turbines. This significantly increasestheir potential to generate electricity.[3]

The wind turbines are expected to provide 11% to 15% of the towers' total powerconsumption, or approximately 1.1 to 1.3 GWh a year. This is equivalent toproviding the lighting for about 300 homes annually.[4] The three turbines were

turned on for the first time on the 8th of April, 2008. They are expected to operate 50% of the time on an averageday.[2]
