“The first skyscraper to integrate large-scale wind turbines suspends three 1,200-megawatt units between its matching 787-foot office towers. The turbines, which were completed in April, supply 15 percent of the electricity for the two buildings—roughly the same amount used by 300 homes.
To maximize energy output, the tapered towers funnel wind between them, creating a negative pressure zone behind the buildings that draws more air through the gap. This suction effect increases wind speeds by up to 30 percent at each of the 95-foot-long rotors to boost electricity production. It also redirects wind gusts hitting the tower by up to 45 degrees off center so that they hit the turbines at a nearly perpendicular angle for optimal electricity generation.” atkinsglobal.com
