SOM invented a new structural system, called a buttressed core, which enabled the building's efficient and economic build out. The design for Burj Khalifa went through extensive wind tunnel testing, resulting in a building that resists high winds while minimizing vibration. Taking advantage of the height, SOM invented a "skysourcing" cooling system to maximize ambient air. It pulls cooler air from the top of the building (which is on average 7° C cooler than the ground) and forces it back down through the building to keep it cool.
