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.

The CTBUH follows the United Nations's definition of City, and thus uses the lists and codes established by that organization.
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.

Height
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."
305.0 m / 1,001 ft
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).
305.0 m / 1,001 ft
Occupied
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
276.7 m / 908 ft

Helipad
Height, measured from the level of the lowest, significant, open-air, pedestrian entrance, to the building's helipad.
300.0 m / 984 ft
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).

About Northeast Asia Trade Tower
The Northeast Asia Trade Tower symbolizes the region’s role as a new center of economic activity and development. The tower embodies the planning principles of New Songdo City, a 607 hectare (1,500 acre), master-planned community on the Incheon, Korea, waterfront. Northeast Asia Trade Tower is a large-scale mixed-use development designed to attract top tier Global and Korean companies as tenants to this new international free-trade zone. Occupying a site centrally located at the southern edge of Songdo Central Park, the tower is adjacent to the Songdo Convensia Convention Center, and near the Songdo First World Towers. The tallest building in Korea at the time of its completion, Northeast Asia Trade Tower rises above the new city offering views of the Yellow Sea, the cities of Seoul and Incheon, and the surrounding mountains.
The tall form tapers from a trapezoid shape at the ground level to a triangle at the top, reflecting the shifting programs within. The tower’s large base accommodates the open floor plates required by office tenants, while the tower’s slender upper floors provide hotel and residential spaces with shallower floor plates, maximizing views and light penetration. The very top of the tower—its observation space—is fittingly paired with the tower’s most slender profile. The transition in plan from trapezoidal to triangular form translates into an elegant exterior with reflective faces that resemble elongated triangles, the edges of which converge and diverge in an alternating pattern.
The form appears to lean toward Songdo Central Park and, in fact, it does bow out by 5m (16ft). This effect is achieved without compromising the tower’s stability. To stabilize the structure of the building, the core rises vertically and the centroid of the tower mass aligns with the centroid of the tower ground level, thereby eliminating any rotational forces in the foundation from the tower form. This results in a very efficient structural system. The concrete core and the lightweight steel floor framing are conventional construction methods resulting in a cost effective building.
Northeast Asia Trade Tower serves as a model of sustainable design strategies, carefully balancing energy conservation, increased indoor environmental quality, and occupant comfort. The exterior glazing allows for abundant daylight penetration and expansive views. Exterior shading devices, together with a high performance glazing specification, limit solar heat gain and reduce air conditioning costs. Operable windows allow for smoke exhaust and small LED lights are embedded into the façade outriggers greatly reducing the energy spent on lighting the building at night.
Like other buildings in New Songdo City, Northeast Asia Trade Tower purchases district hot water from a new, highly efficient cogeneration facility located nearby. Hot water, used for heating and cooling via absorption chillers, is generated from waste heat recovered during the process of producing electricity. The building is estimated to reduce source-energy CO2 emissions by 6,000 tons per year when compared to a “standard” code-compliant office tower with on-site electric chillers and a natural-gas boiler plant.
Because water conservation is a chief concern in Korea, the design for Northeast Asia Trade Tower addresses this issue in several ways. First, low-flow plumbing fixtures reduce water usage by more than 20% in comparison to the consumption rate of a typical office building. Second, a grey water collection system is used for flushing toilets and urinals to further decrease potable water demand and reduce sewage conveyance. Third, the building utilizes collected stormwater for site irrigation via large storage tanks, reducing potable water used for this purpose by more than 50%.
