Height

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).

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.

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
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 Changsha IFS Tower T1
Ideally located in the prime area of Jiefang Road in Furong District, the Changsha IFS Tower T1 complex is well positioned to achieve its primary purpose of attracting a myriad of financial institutions based in Hunan Province. This twin-tower development is based on Harbour City, a hyper-connected retail development in Hong Kong. The Changsha complex will sport an underground network of linkages to a future interchange hub (Wuyi Plaza Station) for metro lines 1 and 2. The same underground passageway will connect with one of the busiest pedestrian streets in China — Huang Xing Pedestrian Shopping Street.
The development features two supertall skyscrapers, with Tower 1 rising 452 meters and Tower 2 rising 315 meters. The rectangular form of the glass-clad towers is neatly interrupted by a series of metal fins that add a hint of complexity to their appearance and reduce glare for the interior office spaces. Tower 1 features a crown that incrementally sets back by several meters at three points, downplaying its extreme height and cementing its relationship with the second tower. Like many towers that break the 400-meter barrier, reduced floor plate sizes at the top are best suited for hotel uses—with guest willing to pay a premium for accommodations at such heights.
At the base, a block-sized podium contains a mega mall of 230,000 square meters, generating triangulation between the office uses above and transportation infrastructure below. Changsha IFS Tower T1 also has 700 meters of retail street frontage, greater than that of its likeness, Harbour City. The retail mall, among the largest in Changsha and Central China, offer s amenities spanning entertainment, lifestyle, culture, and dining under one roof. This important shopping will provide critical activity to the larger development, and the district as a whole.
