Height

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 point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).

Floors

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).

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.

Address
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.

About National Commercial Bank

Constructed as the headquarters for the National Commercial Bank, the design was oriented around central courtyard at the center of the V-shaped office tower. The courtyard was then framed with a staggered arrangement of seven and nine story blocks of office space, allowing for large apertures for light and air to enter the courtyard, filled with a series of outdoor gardens within the center of the structure. Office floors are clad with windows facing the courtyard and solid walls of Roman travertine on the exterior, illuminating interior spaces with ambient sunlight, but eliminating heat gain from direct solar exposure. The courtyard begins just above the banking hall on the ground floor and rises through an opening in the roof, drawing heat naturally through the top of the building as air rises when heated throughout the day.

The southwestern fa├žade of the triangular office tower is joined by a recliner spine, also clad entirely of travertine, which houses all building services and vertical transportation systems, allowing for the offices flanking the courtyard to have large uninterrupted floor pates. The National Commercial Bank is positioned on a large waterfront plaza and is flanked by a cylindrical six story parking garage constructed out of reinforced concrete. When the building opened in 1983, it was the tallest building in Jeddah and made a dramatic visual impact on what at the time was largely low-rise cityscape.
