Sell the barometer and use the money to hire someone to find the answer.
Find a point a which the barometer and the building have the same apparent height. Measure the distance from from eyeball to the barometer and the distance from your eyeball to the building. The ratio of the distances will equal the ratio of the heights.
At least I tried to give original answers!

You could use the old pendulum trick, or you could compare shadow heights, or you could measure the height in barometer lengths but I still think the option to bribe the building superintendent with the barometer is the best.

no mate a barometer is a thing that measures air pressure and tell you the forecast eg. rain wind storm, im not to sure how you could measure a tall building, maybe you could satnd on top if you can get access and then look 45 degrees down, remember that point and measure from that point to the bottom of the building, or maybe you could measure the shadow, or just go in and ask either the receptionest, or at the local council office, im sure that they will have blue prints with all the details on

Drop the barometer from the top of the building and time how long it takes to fall to the ground. Then use d=0.5 g t^2

its hard... you need to take a reading at the bottom, and then at the top. you then need to convert the reading to a measurement above sea level. (that is the hard part).
Most GPS hand held system use this method to work out their height above sea level. It can be very inaccurate because air pressure is not a constant.
You will always get a reading of "above sea level" because this is believed to be the only constant in air pressure.
I know that this doent really answer your question because iot doesnt give you the key of converting the change in pressure to a distance in height. If you find that out you will have your answer!

Though the pressure varies with height, it cannot be considered for accurate measurement of height.
For approximate calculation, up to a height of 500 m, we can take that for an increase of height of one meter the pressure decreases by 11.73 pascal.

ask d watchman by bribing him with the barometer.
