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).

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
All-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 an “all-steel” structure as the concrete elements are not acting as the primary structure.
All-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 and/or steel reinforced concrete which has been precast as individual components and assembled together on-site.
All-Timber
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from timber. An all-timber structure may include the use of localized non-timber connections between timber elements. Note that a building of timber construction with a floor system of concrete planks or concrete slab on top of timber beams is still considered an “all-timber” structure as the concrete elements are not acting as the primary structure.
Mixed-Structure
Utilizes distinct systems (e.g. all-steel, all-concrete, all-timber), one on top of the other. For example, a Steel Over Concrete indicates an all-steel structural system located on top of an all-concrete structural system, with the opposite true of Concrete Over 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 within a composite building’s primary structural elements.

About 3 World Trade Center
As part of the World Trade Center (WTC) master plan in New York’s financial district, 3 World Trade Center is fundamentally linked and fully integrated into its surroundings. The building’s design cannot be understood in a vacuum; rather it is intimately related to, and inspired by, the other structures within the World Trade Center complex. It is located opposite the WTC Memorial and Cultural Center, and at the heart of the cluster of buildings which surround the memorial. As the complex’s commercial core, the tower had to address the issue of balancing retail and office uses, while also complementing and acknowledging the nearby public space.
The building has an orthogonal relationship to the main space between the memorial water pools. To complement this relationship, the central zone of the building reduces in mass as it rises towards the sky. The effect is a stepped profile that accentuates the building’s vertical relative to the memorial, and is sympathetic to the height and positions of the neighboring structures. Spires emphasize the height and slender profile of the building both in the local context, and as part of the Manhattan skyline.
The tower’s podium will house a variety of retail elements and five trading floors, which require large floor plates. Work on the podium took place early in the construction process, but after the project was put on hold in 2012, it stood partially built until construction resumed in 2015. As the building narrows, smaller floor plates will accommodate various office spaces. To maximize sustainability in terms of the building’s day-to-day operations, a number of sustainable design features have been included that are expected to give the building a LEED Gold certification. As part of the World Trade Center master plan, 3 World Trade Center manages to interact with its surrounding environment while still maintaining a sense of independence as a standalone structure.
