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.

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.

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.

Given its central location and commanding form, the R&F Guangdong Building will represent one of several crown jewels in the skyline of Tianjin’s fast-growing central business district. The tower is designed to establish a signature visual profile in the skyline and provide a unique destination for the people of Tianjin and beyond.
Planned as a mixed-use high-rise, the building’s design responds to the programmatic needs of each function. Yet the design is not just a practical conception, it is also responsive to the spatial realities of the site’s location in the Tanggu district. The tower unwraps around its vertical axis as it ascends, similar in nature to an ancient scroll, with a progressively diminishing volume. This unwinding form creates unique opportunities to introduce multi-story atria into the program of each vertical zone. These landscaped interior spaces provide ideal circulation for multi-floor tenants, natural light for deeper spans, and inviting social meeting spaces within the building’s upper floors. The outer shell of the building is to be fitted with high-performance glass and metal, with floor-to-ceiling windows.
Providing intuitive interior and exterior circulation was a high priority for the project. At the base, the site divides vehicular circulation by function, allowing each user to access the tower conveniently from the main roads. A landscaped network of pedestrian pathways connects to a vegetated plaza on the north side of the building, creating a responsive arrival space for the main entrance. Green space is also extended vertically along the exterior, with a green roof topping each of the tower’s setbacks. The overall reduction of impermeable surfaces throughout the complex will allow rainwater to be utilized onsite rather than being directed into the city’s stormwater management system.
