Height
1
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).

Architectural:
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.

Floors
Above Ground
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.

Country

Address
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.

Structural Material
All-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 an “all-steel” structure as the concrete elements are not acting as the primary structure.
All-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 and/or steel reinforced concrete which has been precast as individual components and assembled together on-site.
All-Timber
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from timber. An all-timber structure may include the use of localized non-timber connections between timber elements. Note that a building of timber construction with a floor system of concrete planks or concrete slab on top of timber beams is still considered an “all-timber” structure as the concrete elements are not acting as the primary structure.
Mixed-Structure
Utilizes distinct systems (e.g. all-steel, all-concrete, all-timber), one on top of the other. For example, a Steel Over Concrete indicates an all-steel structural system located on top of an all-concrete structural system, with the opposite true of Concrete Over 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 within a composite building’s primary structural elements.

About Jiangxi Nanchang Greenland Central Plaza, Parcel B
Located across the wide Ganjiang River from the historic center of Nanchang, the Jiangxi Nanchang Greenland Central Plaza, Parcel B and its identical twin tower became the city’s first supertall buildings upon their completion in 2015. Initially planned to top out at 289 meters, the design was then altered midway through construction to reach beyond the 300 meter mark, presenting a significant challenge to the design team. Through adding height to the buildings, the crowns were then sculpted into a series of concave curves and clad with operable glass louvers, opening to allow prevailing winds to pass through the top of the structure, reducing overall loading on the tower structure.
The bases of the towers are aligned to the street with a square ground floor plan featuring rounded corners. As the towers rise, the floorplate is rotated a total of 45 degrees, maximizing views of the nearby riverfront. The rounded corners become more pronounced as the towers rise, blending with the concave indentations of the uppermost floors, creating a tower form which transitions from rigid to organic and is clad in a sleek glass curtain wall which appears to flow across the exterior like a wave. Many of the glass panes as such are not flat and designers took advantage of a newly created production method known as ‘cold bending’ to form the glass panes into the desired specifications of the complex façade.
The base of the towers is made up of a large open lobby, with a highly transparent glass exterior suspended by a grid of cables wrapping the ground floor. This level of clear glass then transitions seamlessly into the blue tinted curtain wall for the remainder of the tower. The main entrances are marked by large stainless steel canopies suspended from freestanding arches by a weave of cables.
The towers flank a view corridor running from a public park, through the center of the complex where the towers are spaced at 100 meters apart and onward towards a street to the northwest. The integrated design relationship with the surrounding context should ensure these towers remain a key focal point in the Nanchang skyline for many years to come.
