Characteristics
The main characteristic of HSBC Hong Kong headquarters is its absence of internal supporting structure.
Another notable feature is that natural sunlight is the major source of lighting inside the building. There is a bank of giant mirrors at the top of the atrium, which can reflect natural sunlight into the atrium and hence down into the plaza. Through the use of natural sunlight, this design helps to conserve energy. Additionally, sun shades are provided on the external facades to block direct sunlight going into the building and to reduce heat gain. Instead of fresh water, sea water is used as coolant for the air-conditioning system.
All flooring is made from lightweight movable panels, under which lies a comprehensive network of power, telecommunication, and air-conditioning systems. This design was to allow equipment such as computer terminals to be installed quickly and easily.
Because of the urgency to finish the project, the construction of the building relied heavily on off-site prefabrication; components were manufactured all over the world. For example, the structural steel came from Britain; the glass, aluminium cladding and flooring came from the United States while the service modules came from Japan.
The inverted ‘va’ segments of the suspension trusses spanning the construction at double-height levels is the most obvious characteristic of the building. It consists of eight groups of four aluminium-clad steel columns which ascend from the foundations up through the core structure, and five levels of triangular suspension trusses which are locked into these masts.
