'I think the key difference between the design of Burj and the design of Kingdom Tower is the approach we took to the shaping of the form in relation to the wind. Burj features a stepped pattern of setbacks that proceed up the toward in a spiraling fashion. Kingdom Tower, on the other hand, is a sloped tower that tapers upward. Like Burj, its base has three "legs," but unlike Burj, the legs ascend in a smooth manner and then terminate at different heights, creating the effect of a plant with leaves that begin to separate at the top. Our wind-tunnel testing indicates that this shape is very effective at 'confusing the wind,' as we say.'
