• The Burj Dubai had its name officially changed to Burj Khalifa during its grand opening in honor of the president of the U.A.E. H.H. Sheikh Khalifa bin Zayed al Nahyan.


• Engineers working on the design considered installing triple-decker elevators, which would have been the first in the world. In fact, the realized building uses double-decker elevators.


• The condensation water collected from the A/C system equals to 20 Olympic-sized swimming pools per year and in turn, used for landscaping.


• Over 330,000 cubic meters of concrete and 31,400 metric tonnes of steel rebar was used at the completion of the tower.


• The tower is situated on a man-made lake which is designed to wrap around the tower and to provide dramatic views of it.


• The top of the building contains a public observation deck and a private club above that.


• Burj Dubai features sky lobbies on levels 43, 76 and 123. These spaces offer fitness and spa facilities. The lobbies on levels 43 and 76 each have a swimming pool and a recreational room for receptions and other gatherings.

• The building sits on a concrete and steel podium with 192 piles descending to a depth of more than 50 metres (164 feet).


• The building was rotated 120 degrees to allow for less stress from the prevailing winds.


• An observation deck will occupy the 124th floor.


• The highest residential floor will be level 109.


• "Burj" is Arabic for "Tower".


• The design by Skidmore Owings & Merrill replaces a plan to reuse the design for Grollo Tower, which was proposed in Melbourne a few years earlier.

• Although the building's shape resembles the bundled tube concept of the Willis Tower, it is structurally very different and is technically not a tube structure.


• A subtle reference to the onion domes of Islamic architecture can be found in the building's silhouette when looking up at the lobes from near the base.
