Height
1
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).

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.

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

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.
residential / hotel / office
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 R&F Guangdong Building
Given its central location and commanding form, the R&F Guangdong Building will represent one of several crown jewels in the skyline of Tianjin’s fast-growing central business district. The tower is designed to establish a signature visual profile in the skyline and provide a unique destination for the people of Tianjin and beyond.
Planned as a mixed-use high-rise, the building’s design responds to the programmatic needs of each function. Yet the design is not just a practical conception, it is also responsive to the spatial realities of the site’s location in the Tanggu district. The tower unwraps around its vertical axis as it ascends, similar in nature to an ancient scroll, with a progressively diminishing volume. This unwinding form creates unique opportunities to introduce multi-story atria into the program of each vertical zone. These landscaped interior spaces provide ideal circulation for multi-floor tenants, natural light for deeper spans, and inviting social meeting spaces within the building’s upper floors. The outer shell of the building is to be fitted with high-performance glass and metal, with floor-to-ceiling windows.
Providing intuitive interior and exterior circulation was a high priority for the project. At the base, the site divides vehicular circulation by function, allowing each user to access the tower conveniently from the main roads. A landscaped network of pedestrian pathways connects to a vegetated plaza on the north side of the building, creating a responsive arrival space for the main entrance. Green space is also extended vertically along the exterior, with a green roof topping each of the tower’s setbacks. The overall reduction of impermeable surfaces throughout the complex will allow rainwater to be utilized onsite rather than being directed into the city’s stormwater management system.
