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.

advantages of the tower shape design
The advantages:
Foundation:
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.

Usage:
The Y-shaped plan is ideal for residential and hotel
usage,
with the wings allowing maximum outward views and
inward
natural light.
Nature : Gradient

and
is topped with a structural

22. 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.

24. Interior Finishes
Interiors
The
interior design of Burj Dubai
public
areas was also done by the
Chicago
Office of Skidmore,
Owings
& Merrill LLP and was led
by
award-winning designer Nada
Andric.

The
interior were inspired
by
local cultural while staying
mindful
of the building's status as
a
global icon and residence
It
features glass, stainless steel
and
polished dark stones,
together
with silver travertine
flooring,
Venetian stucco walls,
handmade
rugs and stone flooring.

safety system
Fire and life safety plan system
The
design of Burj Khalifa undertook with special
attention
to the fire safety and evacuation speed.
The
capacity of concrete surrounds of total
stairwells
besides building service and fireman's
elevator
has been so effective that it can easily
bear
5,500 kg.
That
is why it is known for being the tallest
service
elevator in the world.
Pressurized
and air-conditioned refuge areas
are
designed on almost every 25 floor of this
tower
to ensure better safety as occupants can’t
literally
walk down to 160 floors in one go
