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 Country, and thus uses the lists and codes established by that organization.

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.


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).

Tower GFA

Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

About Academic 3, City University of Hong Kong

Academic 3 connects sectors of the City University of Hong Kong campus and offers a green oasis at its heart. Facilities include classrooms, teaching and research laboratories, multi-function rooms, common areas, administrative offices, a 600-seat lecture theatre, a canteen and a roof garden. In the podium, teaching labs predominate the program, while in the upper section, the administration building contains the board council and Vice Chancellor’s offices, as well as two sky courts, which afford prime views.

The green deck connects the dormitory in the northern campus to the university core, and grows from two to four stories as it progresses toward Cornwall Street. Beneath the open park at roof level, the podium, known as the “Forest of Intellect”, which provides informal meeting space and amenities, accommodates teaching rooms and a 600-seat lecture theatre at its southern tip. By raising the podium above ground level, pedestrian access from the street to the park beyond also gives the public a greater natural resource to enjoy.
