Height
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."

To Tip:
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).

Floors
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).

Name of Complex
A complex is a group of buildings which are designed and built as pieces of a greater development.
Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.
A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.
hotel / office
Structural Material
Steel
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.
Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.
Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.
Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.
Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

About China World Tower
The China World Tower is the third phase and heart of the China World Trade Center (CWTC) in Beijing. The master plan and internal site circulation, both vehicular and pedestrian, were carefully considered in context to the rapidly expanding 3rd Ring Road area and existing Phase I & II programs in the World Trade Center complex to create a vibrant urban center. The project meets the ground with public garden spaces, active retail frontages, and protected courts to bring a sense of urbanity to the entire development. Walkways and open spaces reinforce a pedestrian-oriented environment.
The building was intended to achieve a quiet yet powerful dignity as the marker for the central business district of Beijing. The building is a slender columnar form with articulated corners and surfaces that are faceted in an undulating, waterfall-like plane. The walls are layered with crystalline fins that shade and catch the light, changing the view of the tower as one moves around it. The skyscraper stands in contrast to the jumble of new buildings in the fast-growing area of the city’s central hub.
The tower is said to have 112,000 square meters of total façade area, which is equivalent to 16 standard football fields. The façade features a thermally broken, unitized curtain wall system with low-emissivity insulated glazed units, shaded by full height external vertical glass fins. Because the tower tapers as it rises, the curtain wall undulates on alternating floors to create a micro-texture for the exterior. The external glass fins cantilever 600 millimeters from the glazed façade, providing shading and housing LED lighting strips along the outer edges for nighttime illumination.
Multiple new techniques, including computer simulation and physical tests, were used to examine the behavior of the building at different seismic levels. To achieve the necessary combination of strength and flexibility, engineers introduced a new system to China by adopting a composite steel plate shear wall at the base of the tower. The result illustrates a desirable balance between economics and the structural safety of a high-rise in a high seismic zone.
The tower’s robust base is folded seamlessly into the existing urban fabric and visually anchors the tapering tower. The ground floor contains clearly organized entries to offices on the west and a hotel on the east. The complex acts as a social and commercial hub for the city, with its retail podium drawing a constant bustle of activity to the area.
