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."
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.

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.

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).

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.
