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."

  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).

Chengdu Greenland Center

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
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 Chengdu Greenland Tower

Conforming with the cascade of skyscraper projects advancing in the city – particularly in the booming Dongcun district – [building] blends a keen sense of functionalism with a gutsy, emboldened design that is set to rise above the rest. The tower forms a central component of a larger complex, Chengdu Greenland Center, which will consist of: a retail podium, complete with conference center, a bridge connecting to the main tower, and an exhibition hall; two smaller apartment towers of 173 and 166 meters; and the main tower, containing an array of office accommodations and a luxury hotel. The overall design of the complex interprets and integrates Chengdu’s urban structure and local culture, representing the modern embodiment of Chinese traditional feng shui theory.

The form of the tower was inspired by the unique ice mountain topography around the city, with an angled, mountainous façade that emulates the cool bluish hue of the rocky formations in deep winter. Like the mountain ridges reflecting the light of the sky and the valleys reflecting light from the earth, the tower will perform as a light sculpture to diffuse light from 360 degrees, creating a connection between the ground plane and the sky. A series of inset LED lights along the exterior will enhance this effect at night, causing the tower itself to be an enduring visual centerpiece for the larger development.

Chengdu Greenland Tower’s architecture and structure are married perfectly. The design fully considers the structural requirements of a supertall building in a high seismic zone, using a geometrical plan, a tapered form, and a high-performance damper bracing system to ensure the structure’s stability and efficiency. The building also features an allotment of high-efficiency sustainability systems, including high-performance glass paneling on the exterior.
