I would think that many of the unorthodox methods proposed for measuring
the height of the building are potentially much more accurate than measuring
air pressure differences with a barometer.  Air density (and thus pressure
change with altitude) varies quite a bit with temperature; wouldn't you
need to have a complete knowledge of the air temperature between ground
level and the top of the building in order to get an accurate answer?
