Aedas designs new concourse for Hong Kong International Airport
The Midfield Concourse is located to the west of Terminal 1 and between the two existing runways at Hong Kong International Airport. The project is a five-level concourse with a total floor area of 120,000 sq m and with ceiling heights comparable to those in Terminal 1. There are 20 aircraft parking stands, 19 of which are bridge-served, including two Code F (A380) stands.
The Midfield Concourse is connected to Terminal 1 by an extension of the existing Automated People Mover system. Green features have been fully considered and adopted in the design. These include an optimised glazed facade, with reduced height glazing on the west and increased height glazing on the east, and north facing skylights at regular intervals throughout the Concourse, to maximise natural day lighting and reduce solar gain.
The facade and north lights also make use of very high performance glazing which allows a good level of natural light into the building whilst reflecting over 40% of solar heat. High efficiency water cooled chillers, cooled with recycled condensate, grey and rain water, are used for air conditioning the Midfield Concourse.
Extensive use of over 20,000 LED lights has been incorporated to reduce power consumption. One of Hong Kong's largest arrays of over 1,200 sq m of solar panels is incorporated onto the roof of the Midfield Concourse to harness renewable energy. The design has been carried out as architectural sub-consultant to the Mott MacDonald - Arup JV.
