huge

The tower is so enormous that the air temperature at the top is up to 8 degrees Celsius (14 degrees Fahrenheit) lower than at the base. If anyone ever hit upon the idea of opening a door at the top and a door at the bottom, as well as the airlocks in between, a storm would rush through the air-conditioned building that would destroy most everything in its wake, except perhaps the heavy marble tiles in the luxury apartments. The phenomenon is called the "chimney effect."
