More Achievements!

Burj Khalifa has also broken two other impressive records: tallest free-standing structure, previously held by Toronto's CN Tower and tallest structure, previously held by the KVLY-TV mast in Blanchard, North Dakota. The Chicago-based Council on Tall Buildings and Urban Habitat(CTBUH) has established 3 criteria to decide what makes a building tall, Burh Khalifa wins all the three categories-

  • Height to architectural top
    Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building. This does not include antennae, signage, flagpoles or other functional-technical equipment.
  • Highest occupied floor
    Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest continually occupied floor within the building. This does not include the Maintenance area.
  • Height to tip
    Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element. This can include antennae, flagpoles, signage and other functional-technical equipment.

How does Burj Khalifa handle Air Conditioner system?

The air conditioner system collects air from the upper floors of the building where the air is cooler and cleaner as compared on the ground. At peak cooling times the tower's cooling is 46 MW (62,000 hp) which is equivalent to that provided by 13,000 short tons ( 12,000,000 kg) of melting ice in one day. The water is collected through a condensate collection system which is used to irrigate the nearby park.

Under normal conditions, when all building maintenance units are operational, it takes 36 workers three to four months to clean the entire exterior. The Cleaning system for Burj Khalifa was developed in Melbourne, Australia, by CoxGomyl, a manufacturer of building maintenance units, at a cost of A$8 million (Australian dollar)
