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.

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.

Eleven Times Square Chosen as Featured Building

About Eleven Times Square

Eleven Times Square is a glass-clad commercial tower that occupies a full block front along Eighth Avenue between West 41st and West 42nd Streets in New York City. Designed to extend the vibrancy of Times Square and meet the needs of high-end corporate tenants, its form was derived from an insightful observation of the context. Three independent but interrelated components comprise the structure: a six story ribboned base that wraps the corner of 42nd Street and Eighth Avenue; an outwardly sloped glass-clad “crystal” that preserves sight lines along the 42nd Street corridor; and a 40-story spine that anchors the commercial properties of the building.

Eleven Times Square is an inversion of Manhattan’s zoning paradigm where buildings taper as they rise. Here, the building’s structure along 42nd Street rests on a six-story podium, which reinforces the street’s pedestrian-oriented scale and retail-entertainment environment. The podium terminates in a deep setback that accommodates large scale, three-dimensional LED displays, further contributing to the vibrancy and luminescence of 42nd Street. Set in at its base and then sloping out towards the street line as it progresses upward, the Crystal engages the Westin Hotel across 42nd Street to establish a western gateway to the Times Square. Its distinctive sloped form is crowned with a chiseled profile while preserving views to the landmark Candler and McGraw-Hill buildings. The outward sloping form achieves a civic gesture of gateway, while simultaneously creating more floor area in the upper, valuable portion of the tower.

A site geometry that could not support a center-core building greatly influenced the building’s architecture. Structural engineers determined that a side-core design provided the most efficient lateral and torsional stiffness for the structure. A sloping north face sets the building’s concrete core in the crook of the L-shaped site, offset from the bulk of the tower’s mass. Steel floor framing kept the weight of the building low, reducing torsion and lateral drift induced by the 30-foot cantilever. Due to its efficient configuration and low weight, under wind loads the tower develops tension uplift beneath the concrete core. To resist these forces, a system of rock anchors is installed under the core.

The building’s floor construction and perimeter gravity-supporting structure are steel, providing a flexible structure ideal for the New York office market. The frame maximizes the floors’ regularity and flexibility so that connections and materials are readily accessible to the tenant. Above the fifth floor, column layout is closely coordinated with the architecture to provide column-free corners and façades, maximizing views of the Hudson River and midtown. The building’s southwest corner features a dramatic 45-foot cantilever corner to keep the corporate lobby entrance clear of columns.

Office buildings in this climate are almost always in cooling mode, and therefore the reduction of solar gain was a driver of the building’s form and expression. The building has varying curtain wall treatments on its north and south façades, which are strategically chosen to minimize energy use and create an optimal working environment. The south portion of the building—exposed to the most sun—has reflective glass and perforated aluminum sunshades that cut down on glare and heat. In contrast, the 42nd Street portion is sheer and more transparent welcoming in softer, northern light. The façade is structurally glazed, meaning there are no exterior mullion caps, which can create heat transfer points. Additionally, stainless-steel spacers were used between the lites at the edges of the panels, where curtain walls lose most of their heat, rather than aluminum, which is one of the best conductors available.
