First Skyscraper With Built-In Wind Turbines

The 148 meters, 43 storey, Strata SE1 (also known as The Razor by the local) located in the London, UK, is the world first skyscraper to incorporate wind turbines as part of its building architecture. The three nine-meter wind turbines use a 5-blade design instead of 3-blade to cut down noise and will produce total of 19 kW of power. With 40 mph of wind-speed expected at the top of Strata SE1 every year the turbines could generate 50 MWh of energy, which is equivalent to 8% of the building annual electricity consumption.
