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).
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."
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
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).
The number of floors below ground should include all major floors located below the ground floor level.

Usually involved in the front end design, with a "typical" condition being that of a leadership role through either Schematic Design or Design Development, and then a monitoring role through the CD and CA phases.
The Design Engineer is usually involved in the front end design, typically taking the leadership role in the Schematic Design and Design Development, and then a monitoring role through the CD and CA phases.
Other Consultant refers to other organizations which provided significant consultation services for a building project (e.g. wind consultants, environmental consultants, fire and life safety consultants, etc).
These are firms that consult on the design of a building's façade. May often be referred to as "Cladding," "Envelope," "Exterior Wall," or "Curtain Wall" Consultant, however, for consistency CTBUH uses the term "Façade Consultant" exclusively.
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

Tall Buildings: Imaginative Façades Solutions
Mimi Daraphet, Meinhardt Facade
Façades simply taken in isolation can be complex. A combination of design, engineering, fabrication and installation expertise is important to address all aspects of façade...
Ocean Heights is located in the Dubai Marina development, making an immediate visual impact through a combination of soaring height and the geometry of its form. The building immediately starts to twist its three faces at the base. As it rises, the tower’s floor plates reduce in size, allowing the rotation to become even more pronounced. The building rises over its neighbors. This movement allows two faces of the building unobstructed views of the ocean. The tower breaks away from the orthogonal grid and reorients the project toward one of Dubai’s Palm Islands to the north.
A challenging aspect of the design was accommodating the client’s strict requirement of unit layouts within a challenging envelope. What resulted was a rational 4m (13ft) module, which tracks its way down through the entire building and only changes at the façade. This also considerably simplified the structural system of the project. The shear walls were placed perpendicular to the mean of the two most extreme angles of the façade. This was done to soften the relationship between façade and partitions minimizing how “off-perpendicular” the relationship becomes.

CTBUH has released a study that looks at the recent proliferation of twisting towers creating a new generation of iconic buildings throughout the world.
31 December 2010
In a year dominated by news coverage of the new “World’s Tallest Building” – Burj Khalifa, Dubai – one may be surprised to learn that, besides being the year in which a building first surpassed the 600, 700, and 800-meter thresholds, 2010 has seen the completion of more skyscrapers than any previous year in history.
