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.

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 Nanning Logan Century 1
Nanning Logan Century 1 is a highly organized mix-use development that manages to incorporate a wide variety of programs without overcomplicating the building’s structure. The tower’s shape recalls that of a blossoming flower. The rectangular building appears to be divided into four parts – each representing a flower petal beginning to bloom. At the top of the structure, a helipad joins the petals together. Along the height of the building, layers of secondary petals mimic the motif at the zenith of the structure.
The variability of the building’s programs (including office space, an observation deck, and a hotel) required the project team to carefully scrutinize all design elements to ensure that they function as a complete whole. This was a particularly important consideration when designing the central core of the tower in order to accommodate all elevator requirements for passengers and goods, fire egress, and structural support. The ultimate solution was to create a series of separated vertical transportation systems. There are separate shuttle lifts for the public to reach the observation deck and hotel guests to go to the sky lobby; three lift zones for office users; and an independent entrance for hotel staff. Taking advantage of varying levels at the ground floor, lobbies are clearly segregated for the different groups of users.
The shell of the building functions as a unifying element for the disparate functions within. The façade system utilizes a curtain wall with aluminum vertical fins. These fins are not only decorative, but also serve to reduce solar heat gain. To differentiate the exterior visually, glass is tinted different colors along each section of the tower, ranging from white to grayish-blue.
