The Strata: World’s First Skyscraper With Built-In Wind Turbines

Prepare to be blown away: the latest addition to London ‘s skyline is a striking modern skyscraper that is heralded as the world’s first building with wind turbines  built in! Nicknamed “The Razor”, the 148 meter-tall Strata tower  is topped with a trio of turbines that will produce enough power to meet 8% of its energy needs.

We’ve seen skyscrapers studded with wind turbines  before, but the Strata  is the first building to integrate turbines directly into its facade. Developed and contracted by Brookfield Europe , the tower is a tricky engineering feat indeed, especially granted the gusty blasts of wind that construction crews had to deal with while raising it.
Measuring in at 42 stories tall, the Strata tower has enough height to eclipse the buildings surrounding it, allowing it to take full advantage of the area’s 35mph wind speeds. The tower is also designed to utilize the Venturi effect  created by nearby structures to force wind through the turbines at accelerated rates, generating an expected 50MWh of electricity annually.
According to The Guardian , each of the building’s 19KW turbines will have 5 blades rather than 3, which will reduce noise during operation. Meanwhile a five-ton base outfitted with vibration dampers will keep the building securely anchored to the earth. The skyscraper will also boast other green building strategies such as the exclusive use of natural ventilation , high-performance glazing, and other energy efficiency measures that will keep the building’s power use 6% below current building requirements.
The Strata tower cost £113 million and is set to complete construction this April. The skyscraper’s revolutionary design makes bold steps towards meeting the UK’s requirement that all new buildings be zero-carbon by the year 2019.
