Dubai - inside the Burj Khalifa elevator

The world's tallest building, Burj Khalifa, occupies third place in the world fastest elevator list, with a maximum elevator speed of 36 km/h, or 600m/min. The engineers working on the design first thought about installing triple-decker elevators, which would have been the first in the world. The double-decker elevators that have instead been installed have a capacity of 12 to 14 persons per cabin.
