Debate over definition

The assessment of the height of artificial structures has been controversial. Because varying standards have been used by different organizations, the accepted height of these structures or buildings depends on which standards are accepted. The Council on Tall Buildings and Urban Habitat has changed its definitions over time. Some of the controversy regarding the definitions and assessment of tall structures and buildings has included the following: * the definition of a structure, a building and a tower * whether a structure, building or tower under construction should be included in any assessment * whether a structure, building or tower has to be officially opened before it is assessed * whether structures built in and rising above water should have their below-water height included in any assessment. * whether a structure, building or tower that is guyed is assessed in the same category as self-supporting structures. Within an accepted definition of a building further controversy has included the following factors: * whether only habitable height of the building is considered * whether communication towers with observation galleries should be considered "habitable" in this sense * whether rooftop

Tallest buildings

Up until the late 1990s, the definition of “tallest building” was not altogether clear. It was generally understood to be the height of the building to the top of its architectural elements including spires, but not including "temporary" structures (such as antennas or flagpoles), which could be added or changed relatively easily without requiring major changes to the building's design. Other criteria for height measurement generally were not considered, which occasionally caused some controversy. One historic case involved the building now famous for the

(CTBUH) found the Willis Tower (without its antennas) to be the third-tallest building, and the Petronas Towers (with their spires) to be the world's two tallest buildings.

This measurement is the most widely used and is used to define the rankings of the 100 Tallest Buildings in the World. # Highest Occupied Floor # Height to Top of Roof (omitted from criteria from November 2009 onwards) # Height to Tip The height-to-roof criterion was discontinued because relatively few modern tall buildings possess flat rooftops, making this criterion difficult to determine and measure. The CTBUH has further clarified their definitions of building height, including specific criteria concerning subbasements and ground level entrances (height measured from lowest, significant, open-air, pedestrian entrance rather than from a previously undefined "main entrance"), building completion (must be topped out both structurally and architecturally, fully clad, ''and'' able to be occupied), condition of the highest occupied floor (must be continuously used by people living or working and be conditioned, thus including
