It sounds like the original question was just badly worded. It should have read "Show how it is possible to determine the height of a tall building using only a barometer.". The other answers, while not incorrect, do assume the availability of additional items such as rope and watches.

Doing it the "right" way would also require the stairs (well, and elevator would work for that too, but I would count the elevator as an additional item which itself uses complex mechanics and cables to get you to the top.)
