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."

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).

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.

hotel / office / serviced apartments

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 Suzhou IFS

Suzhou IFS aims to be a landmark on the city’s skyline in both form and function, drawing upon modern design practices to belay the area’s historical repertoire. Conceived as a mixed-use high-rise, the tower will incorporate a number of disparate programs, embodying a modern 21st century presence that is symbolically tied to the city’s identity.

Suzhou has long been a center of trade in China, and the building’s design pays tribute to this achievement. The tower’s form is reminiscent of a fish, a symbol of prosperity and a nod to the role that water has played in the city’s history and identity—the city is surrounded by lakes and canals, causing it to become known as “Venice of the East.” As such, the tower is designed to interact with the surrounding bodies of water. The tower gestures towards Jinji Lake and opens out towards the water.

Soaring upwards, the curved “tail” of the fish subtly transitions from the scale of the lake and surrounding buildings to the top of the tower. More than an architectural embellishment, the flared base maximizes views of the water for the serviced apartments within and considerably lengthens its street frontage. At night, the tower cladding is articulated with glowing LEDs. These lights activate in a staggered timing that causes the building to shimmer in the evening skyline, much like the nearby lake.

The tower form and orientation, together with the articulation of the west façade, diminishes much of the heat and glare, while bringing more natural daylight to the internal spaces. The tower cladding is a high-performance glazing that significantly mitigates solar loading.
