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.

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."

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).

# of Apartments

Number of Apartments refers to the total number of residential units (including both rental units and condominiums) contained within a particular building.

About Sky House

Sky House is located in midtown Manhattan adjacent to the historic landmarked Church of the Transfiguration also known as the “Actors Church.” All of the development rights (“air rights”) of the historic structure were utilized in order to take full advantage of the limited site footprint, and in thus achieving its overall height. Parish hall facilities for the church are located in the base of the tower. They include meeting/reception rooms, classrooms and offices. The building’s width varies from only 8.8 meters to 15.2 meters (29–50ft) resulting in a highly attenuated slender structure with slenderness ratios ranging from 1:12 at its maximum width to 1:20 at its narrowest.

In order to provide the necessary stability against wind and gravitational loads, concrete shear walls were integrated with the architectural plan not only around the stairs and elevators, but also between units and at the perimeter. The perimeter condition integrates the structure in an inventive pattern of tightly spaced piers and vertically oriented floor-to-ceiling windows. The tower’s dynamic characteristics were designed to tune out the aerodynamic wind effects to a level that satisfied human comfort criteria without the use of supplemental damping systems. The design has only three interior columns which provided flexibility to apartment layouts as well as simplifying construction— achieving a two-day poured-in-place concrete cycle for each floor.

To help Sky House blend with its lower-scale surroundings, the building is divided vertically into three slender masses. The base differentiates itself from the tower with a finely articulated, vertical prismatic glass curtain wall that establishes a graceful and slightly ecclesiastical expression to the façade. The church’s parish house is a new three-story structure at the base of the tower that projects forward to the sidewalk, thus extending the scale and refined architectural detail of the church compound toward the east. At street level, the tower graciously becomes a backdrop to the parish hall and other low-scale structures. The architecture of the parish hall façade provides a transition between the historic church and the minimalist vertical expression of the tower.
