Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).
The number of floors below ground should include all major floors located below the ground floor level.

Other Consultant refers to other organizations which provided significant consultation services for a building project (e.g. wind consultants, environmental consultants, fire and life safety consultants, etc).
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

Los Angeles Skyscraper Slide Won't Reopen
A renovation will do away with a slide that gave thrill-seekers a brief ride on the outside of a downtown Los Angeles skyscraper. The new...
When built, U.S. Bank Tower was the first supertall building, not just in Los Angeles, but also in the entire western United States to the west of Chicago and Houston. Originally known as Library Tower, it was constructed across the street from the historic Central Library of Los Angeles and was developed utilizing air rights purchased from the city, preserving the historic open setting of the low-rise building. Its Art-Deco-via-Post-Modern design took cues from established local icons of the 1920s, including City Hall and the Central Library. It is also notable for the public-realm improvements at its base, which is built into a hill. A cascading set of waterfalls and stairs descends around the perimeter.
When built, U.S. Bank Tower was the tallest structure to be located in a seismically active area. Designers based the layout of the tower plan on a concept of overlapping geometries, a circular form superimposed onto a rectilinear matrix, a shape that is translated to the outside of the building and extruded upward into a series of upper level setbacks and a textured façade made up of triangular window bays. The triangular bays are repeated in the crown with more pronounced angles providing greater visual distinction between it and the tower below.
At ground level, development of the tower incorporated the creation of the Bunker Hill steps, a pedestrian link ascending the topographical change between the modern downtown towers built in the Bunker Hill area primarily in the mid to late 20th century and the shorter early 20th century buildings of the historic downtown core.
U.S. Bank Tower has dominated the Los Angeles skyline as its tallest building for 27 years, and has been seen in the backdrop of numerous films produced by Hollywood studios. Its presence will remain a key feature of the skyline, even as its title of the city’s tallest has since passed on to Wilshire Grand Center and as other changes occur to downtown Los Angeles in the in the years to come.
When completed, it was the world's tallest building in a seismic zone.
Features a 45 ft (13.7 m) slide that hangs off the side off the building 1,000 ft (304.8 m) above ground.
First building to be destroyed by aliens in the 1996 movie "Independence Day."
