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 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 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 current legal building name.
Other names the building has commonly been known as, including former names, common informal names, local names, etc.
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.
The CTBUH follows the United Nations's definition of Country, and thus uses the lists and codes established by that organization.
The CTBUH follows the United Nations's definition of City, and thus uses the lists and codes established by that organization.
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.
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 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."

The number of floors below ground should include all major floors located below the ground floor level.
Number of Hotel Rooms refers to the total number of hotel rooms contained within a particular building.
Number of Parking Spaces refers to the total number of car parking spaces contained within a particular building.
Number of Elevators refers to the total number of elevator cars (not shafts) contained within a particular building (including public, private and freight elevators).
Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

The Wilshire Grand Center marks a new era for tall buildings in Los Angeles; it will be an exciting addition to the visual character of the Downtown area, and offer a contemporary contrast to its surroundings with its sail-shaped form. The development will boast luxury hotel rooms, restaurants, businesses, and nightlife options. Topped with a curved roof that diverges from the traditional flat roof style of most tall buildings nearby, the Wilshire Grand Center will rise well above its surroundings. The tower is designed to be the tallest structure in the Los Angeles skyline, and will do much to add to the cultural and economic vibrancy of the neighborhood.
The project team strove to design a high-performing building that intelligently addresses the specific environmental issues facing Southern California. Architects and engineers employed the latest construction techniques and sustainability considerations to ensure that this project is built and operated in a way that is ecologically responsible, and will allow the building to achieve a LEED Silver certification. The design team worked closely with the City of Los Angeles to incorporate strategies such as thermal energy storage and the reuse of storm water in cooling towers. Innovative lighting and climate systems are also in place to significantly reduce overall energy consumption.
The city’s culture and climate are celebrated with a strong sense of indoor/outdoor relationships created at every practical opportunity. Ballrooms open directly onto gardens, the prefunction space extends to a terrace, pool decks are lined with cabanas, and outdoor meeting rooms encircle fire pits. The hotel rooms and office space feature floor-to-ceiling glass to maximize the spectacular views of Santa Monica and the Pacific Ocean, the Hollywood Hills, and the San Gabriel Mountains.
