World's Fastest Elevators (Work)

CLMECH-CF4PRW

The tallest building in the world (right now) is Dubai’s Burj Khalifa with 163 floors, featuring an observation deck on the 124th floor (452 m high). There is also an express elevator that can take 12-14 people from the ground floor to the 124th floor in 60 seconds.

For a load of 12 people averaging 70.0 kg each, how much work is the elevator’s motor doing on each trip up?
