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."

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).

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.

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.

office / residential / hotel
Structural Material

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 a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced 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.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/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 in a composite building’s core, columns, and floor spanning separately.

About De Rotterdam

De Rotterdam is conceived as a vertical city: three interconnected mixed-use towers accommodating offices, apartments, a hotel, conference facilities, shops, restaurants, and cafes. The towers are part of the ongoing redevelopment of the old harbor district of Wilhelminapier, next to the Erasmus Bridge, and aim to reinstate the vibrant urban activity – trade, transport, leisure – once familiar to the neighborhood. De Rotterdam is named after one of the ships on the Holland America Line, which departed from the Wilhelminapier in decades past, carrying thousands of Europeans emigrating to the US.

De Rotterdam consists of three connected towers that appear as stacked and shifted volumes upon a base plinth. The façade design has been kept neutral and transparent; the dynamic appearance of the building is determined by the varied day cycles of the different programs. The deep mullions allow the glazed facades to appear more open or closed, depending on the perspective.

De Rotterdam is an exercise in formal interpretation that is at once reminiscent of an imported mid-century American skyscraper, but epitomizes the off-center experimentalism of modern Dutch art of the foregoing century. The nighttime twinkling of the lights indicating different programs throughout the day lends dynamism and contributes to the humanization of the monoliths. It is as if the moai of Easter Island were constantly craning their necks and raising their eyebrows at the change all around.

At ground floor level, a ceiling height of 8.5 meters ensures a smooth transition between exterior and interior, while loading areas are kept, as much as possible, to other levels. The street-side entrance zone is separated from the waterfront restaurant zone by only a relatively small core, and a large central lobby ensures that a visual connection between street and waterfront remains. The public program on the upper floors of the plinth meets the ground floor in a large atrium; this void extends externally between the low-rise tower volumes to 85 meters’ height. Once within the towers, views between the hotel, office and residential volumes continue the theme of transparency.

The architectural concept produces more than sheer size: urban density and diversity – both in the program and the form – are the guiding principles of the project. De Rotterdam’s stacked towers are arranged in a subtly irregular cluster that refuses to resolve into a singular form, and produces intriguing new views from different perspectives. Similarly, the definition of the building changes according to its multiple uses internally.

The various programs of this urban complex are organized into distinct blocks, providing both clarity and synergy: residents and office workers alike can use the fitness facilities, restaurants, and conference rooms of the hotel. These private users of the building have contact with the general public on the ground floor, with its waterfront cafes. The lobbies for the offices, hotel, and apartments are located in the plinth – a long elevated hall that serves as a general traffic hub for De Rotterdam's wide variety of users.

Comprehensive building management, including an energy monitoring system, has been employed to ensure maximum efficiency throughout De Rotterdam. For the purpose of energy supply, a collective generation system was developed, which feeds all the functions in the building. Power is generated via district heating and co-generation with biofuel, while water from the adjacent Maas river is used for cooling. The temperature system additionally uses low-temperature heating and high-temperature cooling, heat exchangers for heat recovery ventilation, and fan speed to control air handing.

Maximum use of daylight is supplemented by efficient artificial lighting, using high-efficiency reflectors. Appropriate lighting methods have been selected for the various functions, with automatic daylight and motion control in the office areas, and LEDs in the public zones. Sustainability is further improved with water saving taps and reservoirs, and efficient elevators using energy recovery.
