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.
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).
The number of floors below ground should include all major floors located below the ground floor level.
The current legal building name.
Other names the building has commonly been known as, including former names, common informal names, local names, etc.
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.
The CTBUH follows the United Nations's definition of City, 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.
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.

Number of Elevators refers to the total number of elevator cars (not shafts) contained within a particular building (including public, private and freight elevators).
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.

Usually involved in the front end design, with a "typical" condition being that of a leadership role through either Schematic Design or Design Development, and then a monitoring role through the CD and CA phases.
Usually takes on the balance of the architectural effort not executed by the "Design Architect," typically responsible for the construction documents, conforming to local codes, etc. May often be referred to as "Executive," "Associate," or "Local" Architect, however, for consistency CTBUH uses the term "Architect of Record" exclusively.
The Design Engineer is usually involved in the front end design, typically taking the leadership role in the Schematic Design and Design Development, and then a monitoring role through the CD and CA phases.
The Peer Review Engineer traditionally comments on the information produced by another party, and to render second opinions, but not to initiate what the design looks like from the start.

The CTBUH lists a project manager when a specific firm has been commissioned to oversee this aspect of a tall building’s design/construction. When the project management efforts are handled by the developer, main contract, or architect, this field will be omitted.
Other Consultant refers to other organizations which provided significant consultation services for a building project (e.g. wind consultants, environmental consultants, fire and life safety consultants, etc).
These are firms that consult on the design of a building's façade. May often be referred to as "Cladding," "Envelope," "Exterior Wall," or "Curtain Wall" Consultant, however, for consistency CTBUH uses the term "Façade Consultant" exclusively.
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

Al Hamra Tower stands as an icon symbolizing Kuwaiti national pride. The form of the building appears to be cut from a prism, a void taken from the center, with each floor plate rotating counter-clockwise around the core. The result is a spiraling geometry that unravels to the top. The void, which shifts from west to east, exposes the solid southern core wall, which is visually distinct from the other glazed and transparent walls wrapping around the rest of the building. Two solid “flared walls” provide the transition between these two conditions, covering the complex geometry of the rotating floor plates.
The southern façade, exposed through the central void, is clad in stone with angled window cuts to respond to the intense solar conditions of the area. The same material treatment is given to the flared walls that cover the curvilinear faces along the edge of the spiral void, only without window openings. The concrete construction of these elements also allows them to act as thermal mass walls, slowing heat gain during the day and releasing stored heat at night. The curved east, north, and west façades are clad in vision glass, providing clear views of the surrounding city and Kuwait Bay while also optimizing the spaces against glare and heat gain.
At the north side of the building is the main lobby, a 24-meter-high space that extends from the building core to the perimeter frame. To increase the area of the lobby, the columns along the exterior slope inwards, forming an intricate lamella structure that is both functional and elegant. At the top of the tower, a 40-meter-high space with a restaurant and observation deck provides far-reaching views of the city. To produce these unobstructed views, a cantilevered steel truss system was employed to support the roof and curtain wall glazing, reducing the necessary columns in the space.
