Some Interesting Facts About The Burj Dubai
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.
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 elevators have the world’s longest travel distance from lowest to highest stop.
Hot air on the outside condense due to the large cooling needs of the building. The condensation is collected and used to water the buildings
flora and fauna. 20 Olympic-sized swimming pools per year of water.
There are 1,210 fire extinguishers on the site.
At the peak cooling times, the tower require approximately 10,000 tons of cooling per hour.

The
tower superstructure of
Burj
Khalifa is designed as an all
reinforced
concrete building with
high
performance concrete from
the
foundation level to level 156,
and
is topped with a structural
steel
braced frame from level 156
to
the highest point of the tower.
The
structure of Burj Khalifa was
designed
to behave like a giant

Cladding system in general
Cladding system: curtain
wall
Cladding material: Stainless
Steel
The
exterior cladding is comprised of reflective
glazing
with aluminum and textured stainless steel
spandrel
panels and stainless steel vertical tubular
fins.
Close
to 26,000 glass panels, each individually
hand-cut,
were used in the exterior cladding of
Burj
Khalifa.
Over
300 cladding specialists from China were
brought
in for the cladding work on the tower.
The
cladding system is designed to withstand
Dubai's
extreme summer heat, and to further
ensure
its integrity, a World War II airplane
engine
was used for dynamic wind and water
testing.
The curtain wall of Burj Khalifa is equivalent to 17
football
(soccer) fields or 25 American football fields.
