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.

The main contractor is the supervisory contractor of all construction work on a project, management of sub-contractors and vendors, etc. May be referred to as "Construction Manager," however, for consistency CTBUH uses the term "Main Contractor" exclusively.

What Makes for Tall Building Innovation?

This building houses Sony’s R&D department, taking the form of a thin vertical plate to ensure good views, while minimizing the heat island effect by positioning its narrow sides against prevailing winds. The building was conceived as a massive cooling device. Owing to the narrowness of the building, the offices have flexible, open plans without columns. All the building’s mechanisms are integrated into the facades, which were designed in response to the environment.
The eastern façade is covered with specialized ceramic louvers that guide rainwater through the system to act as enormous radiator for cooling the environment. Thus, instead of contributing to the heat island effect, the building operates as an urban “cool spot.” This is the first building to install Bioskin, a simple system that circulates rain water by using electricity generated by solar power through unglazed terracotta pipes arranged along the façade vaporizes, cooling down the building itself as well as the surrounding area.
