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.

Height
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."
217.0 m / 712 ft
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).
217.0 m / 712 ft
Occupied
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
209.0 m / 686 ft
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).
51
Floors Below Ground
The number of floors below ground should include all major floors located below the ground floor level.
2
# of Parking Spaces
Number of Parking Spaces refers to the total number of car parking spaces contained within a particular building.
541
Top Elevator Speed
Top Elevator Speed refers to the top speed capable of being achieved by an elevator within a particular building, measured in meters per second.
8 m/s
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.
118,000 m² / 1,270,141 ft²

About International Towers Sydney Tower 1
Constructed on a former container port, International Towers Sydney Tower 1 was part of the three building International Towers complex and part of the larger redevelopment of Barangaroo South into a new waterfront extension of Sydney’s Central Business District. International Towers was conceived as three sibling buildings with varying heights and specific design features to provide each building with its own identity. One of the identity markers is the in the arrangement and color of the vertical solar shades applied to the exterior facades, improving the thermal performance of the buildings as they were comprehensively designed with the context of their surroundings. The elevator cores were positioned to the northern edge of each building footprint, providing for expansive office floor plates while also further reducing energy consumption through a reduction of glazing on each building’s northern exposure.
Designing workspaces around social interaction was a key part of the design process, providing communal meeting areas beside the elevator cores interlinking workers throughout each building, while the entirety of the roofs, both at the podium and uppermost levels, are also available as open air terraces, courtesy of utilizing a centralized mechanical plant to efficiently provide services to all three buildings. At street level, all three buildings share a common basement and single entry point for vehicles in order to enhance the pedestrian friendliness of where the towers meet the ground.
