Something don't jive with these figures. The building is 508 meters tall, with 101 floors. Yet, the 89th floor observation deck is reached by 1,010 meters of elevator travel.
Taipei 101 either has the worlds most ineffecient elevators. Or the 89th floor exists in the 5th dimension.
I believe that the elevators travel sideways also. I am not 100% positive but I recall a discussion about it and can't remember if it was about this building or one that is being proposed.
