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

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.

All-Concrete

Height
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."

99.8 m / 327 ft

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).
99.8 m / 327 ft
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).

Floors Below Ground
The number of floors below ground should include all major floors located below the ground floor level.

Tower GFA
Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

About Covent Garden Tower B

Covent Garden is comprised of a high-rise and low-rise building, meant to become an urban signal announcing the North area, the only purpose-built high-rise business district of Brussels. From an urban point of view, the project blends in as much with the historic low-rise buildings it faces on one side, as it copes with the tall buildings it faces on two other sides. At ground level a pedestrian link is created between an existing park and a major public square via a landscaped garden-atrium.

The project implements many sustainable features, including operable window-boxes that allow for natural ventilation yet do not allow rainwater into the building. A radiant air-conditioning system is used, in which less energy is used to achieve the same comfort level as a traditional air-conditioning system. The radiant air-conditioning system or “cold ceiling” requires negligible maintenance and a very low overall cost. Fresh air enters the offices through ventilation grills in the ceilings and is extracted near the lighting after being drawn across the offices.

Lastly, Covent Garden is equipped with an installation which in its specific application is a first in Belgium: the garden of the atrium is not only a major meeting space within the complex, it is also an “Eco-Machine” meant to organize wastewater recovery.

The Eco-Machine is a wastewater treatment process that treats both grey and black water, using advanced biological and bacteriological purification techniques. The system proceeds initially by sedimentation in a septic tank and biological purification with nitrification: the bacteria are held in free suspension in the water and the biomass is filtered through membranes. In a second stage, the water transits via the covered garden into vats with helophytes, which play a fine purification role.

The objective is to treat this water so that it can be recycled into the building’s own consumption cycle. Water is recovered at the end of the process and is stored in a pond. Although not drinkable, it is re-injected into the building for sanitary uses (washrooms), for building maintenance and for watering the plantings.
