World Records

       At over 828 metres (2,716.5 feet) and more than 160 stories, Burj Khalifa holds the following records:
  • Tallest building in the world
  • Tallest free-standing structure in the world
  • Highest number of stories in the world
  • Highest occupied floor in the world
  • Highest outdoor observation deck in the world
  • Elevator with the longest travel distance in the world
  • Tallest service elevator in the world 
  • Tallest of the Supertall
       Not only is Burj Khalifa the world’s tallest building, it has also broken two other impressive records: tallest structure, previously held by the KVLY-TV mast in Blanchard, North Dakota, and tallest free-standing structure, previously held by Toronto’s CN Tower. The Chicago-based Council on Tall Buildings and Urban Habitat (CTBUH) has established 3 criteria to determine what makes a tall building tall. Burj Khalifa wins by far in all 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 includes spires, but does not include antennae, signage, flagpoles or other functional-technical equipment. This measurement is the most widely used and is used to define the Council on Tall Buildings and Urban Habitat rankings of the Tallest Buildings in the World.

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. Maintenance areas are not included.


Architecture
       The architecture features a triple-lobed footprint, an abstraction of the Hymenocallis flower. The tower is composed of three elements arranged around a central core. The modular, Y-shaped structure, with setbacks along each of its three wings provides an inherently stable configuration for the structure and provides good floor plates for residential. Twenty-six helical levels decrease the cross section of the tower incrementally as it spirals skyward.

       The central core emerges at the top and culminates in a sculpted spire. A Y-shaped floor plan maximizes views of the Arabian Gulf. Viewed from the base or the air, Burj Khalifa is evocative of the onion domes prevalent in Islamic architecture.
