Ranking criteria and alternatives


Emporis ranks the buildings by highest architectural structural element, which means
 * height of spire, statue, or any other architecturally integral element count towards the height of the building;
 * height of antenna, flagpole, or other detail not classified as architecturally integral element does not count towards the height of the building;
 * roof height is only relevant if no higher architecturally-integral element is present.

Taipei 101, the Petronas Twin Towers, and the Empire State Building]] This naturally hurts the rankings of buildings without spires, or with antennas instead of spires. The most famous such discrepancy is that Petronas Towers, with its spire, is ranked higher than the Sears Tower with its antennae, despite the Petronas Towers' lower roof and lower highest point (of spire/antenna).

Alternative lists of high buildings are maintained by the non-governmental Council on Tall Buildings and Urban Habitat. These lists, first defined and compiled in 1996 as a response to the dispute as to whether the Petronas Towers or the Sears Tower was taller, rank buildings in four categories: height of structural or architectural top; height of highest occupied floor; height to the top of roof; height to top of any part of the building. Currently Taipei 101 tops the category of highest structural element, at 509 m. Sears Towertops the highest point, at 527 m. Shanghai World Financial Center tops the roof height, at 492 m.
