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).
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.
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).
Below Ground
The number of floors below ground should include all major floors located below the ground floor level.

Function
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 / residential / office
Structural Material
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 Keangnam Hanoi Landmark Tower
Upon completion in 2012, Keangnam Hanoi Landmark Tower was the tallest building in Vietnam and was a redefining moment for the city of Hanoi, which at the time had very few tall buildings. The 72 story building is comprised of offices and is the tallest in a three building complex featuring two 49 story residential towers with curved facades to maximize views. While the complex is located on the western edge of the city, the placement positions the development within the center of a newly established central business district.
In order to construct the complex in the soft soils of Hanoi, 980 piles with diameters of up to two meters across were drilled deep underground in a process which took longer than one full year during the construction phase. The reinforced concrete frame of the 72 story tower utilized post-tensioning which allowed the structure to rise as quickly as of one floor every five days, a rate which is faster than what would have occurred with conventional construction techniques. Cladding the tower is a double glazed façade, producing a desired modern aesthetic for the exterior which combined with an intelligent building systems technology, provides a high level of energy efficiency. At the peak of construction, the worksite employed as many as 8000 people at one time.
The base of the Keangnam Hanoi Landmark Tower is attached to a shared podium structure containing shops, a department store and a cinema from which all three towers then rise. The main tower then is comprised of offices on floors 12-46, serviced apartments on floors 48-60 and a full service hotel on floors 62-70. The uppermost 72nd floor contains an observatory with a panoramic view of Hanoi and its rapidly growing skyline.
