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 main contractor is the supervisory contractor of all construction work on a project, management of sub-contractors and vendors, etc. May be referred to as "Construction Manager," however, for consistency CTBUH uses the term "Main Contractor" exclusively.
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).
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

High-Rise Hotel Proposed for Sydney’s Darling Harbour
ASX-listed casino operator Crown Resorts has unveiled early images for Sydney's first six-star hotel and its serviced apartments at One Barangaroo, a controversial AU$2.4-billion (US$1.6-billion)...
Constructed on a former container port, International Towers Sydney Tower 2 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.
