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).

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.

About Riviera TwinStar Square 1

The towers are occupied by two different bank headquarters. Thus a key element of the design was to create symmetrical towers that are all about balance, order, and stability. Their interdependence sends the message of union and respect for each other simultaneously. The stone and glass towers rise in tandem to form a gateway to the Huangpu River. As they face each other, their façades curve dramatically to form an implied space that frames the sky and the city skyline. The facing inner curves are lit at night to emphasize the distinctive shape and monumental scale of the space.

This site is designed with the intention of integrating a high profile urban space within a new state of the art, highly modern business environment. This adds a sense of place, or destination, to an already popular area, where the community can utilize and enjoy the river landscape and partake in various recreational activities. In this sense, the main buildings are interconnected by an elevated platform which serves as weather protection for the indoor pedestrian corridor below, and above provides an outdoor public space. The project created specifically a raised basement level to cater to the height of the Huangpu River’s flood protection systems.

The architectural design is aimed at the needs of a flagship financial tenant, providing an efficient floor plate and special consideration to specialized trading floors and private meeting spaces. A removable slab area was integrated into the plan to accommodate flexibility for tenant needs, allowing connectivity to floors above and below for larger firms, or these can be kept closed for smaller tenants that will only occupy single floors. Individual MEP areas are reserved to help ensure the high electricity supply requirements for financial institutions.

The façade comprises unitized high performance Low-E glass, with solar control coating. Natural stone and aluminum cladding serve to add a distinctive patterned feature across the elevations, giving the towers a distinctly Chinese feel, and thus further grounding them in their local context. All the façade materials were procured locally in China and are recyclable.

A conventional reinforced concrete frame core wall system was adopted for the tower. However, some special structural features have been used for this project. Inclined columns are used at the curved elevations face to face to integrate the structure into the architectural form. Steel Reinforced Columns (SRC) are used in the lower part of the towers to minimize column sections and the lost floor area that would have been needed for larger columns.

Riviera TwinStar Square Chosen as Featured Building

This building has a fantastic balance and poise. The towers stand out for the new spatial dimension they give to the “emptiness” that lies between them.
