Beijing Daxing International Airport
Beijing Daxing International Airport (BDIA) is a new airport in the Daxing district 46km south of the city centre. Developed to alleviate congestion at the capital’s existing airport, BDIA will be a major transport hub for the region with the world’s fastest growing demand for international travel and is fully integrated within the country’s expanding transport network.
Echoing principles within traditional Chinese architecture that organize interconnected spaces around ua central courtyard, the terminal’s design guides all passengers seamlessly through the relevant departure, arrival or transfer zones towards the grand courtyard at its centre – a multi-layered meeting space at the heart of the terminal. Eight flowing forms within the terminal’s vaulted roof reach to the ground to support the structure and bring natural light within, directing all passengers towards the central courtyard. Natural light also enters the terminal via a network of linear skylights that provide an intuitive system of navigation throughout the building, guiding passengers to and from their departure gates. Structural spans of up to 100m provide the terminal’s generous public spaces and allow the highest degree of flexibility for any future reconfiguration.
The compact radial configuration of the terminal allows a maximum number of aircraft to be parked directly at the terminal with minimum distances from the centre of the building, providing exceptional convenience for passengers and flexibility in operations. 79 gates with airbridges connect directly to the terminal while BDIA’s facilities can quickly process the passengers of six full A380 aircraft simultaneously. Five aircraft piers radiate directly from the terminal’s main central court where all passenger services and amenities are located, enabling passengers to walk the comparatively short distances through the airport without the need for automated shuttle trains.
As a result, the terminal’s compact design minimises distances between check-in and gate, as well as connections between gates for transferring passengers. This radial configuration ensures the farthest boarding gate can be accessed in a walking time of less than 8 minutes. Photovoltaic power generation is installed throughout the airport to provide a minimum capacity of at least 10MW. BDIA’s centralised heating with waste heat recovery supported by a composite ground- source heat pump system incorporating a concentrated energy supply area of nearly 2.5 million m.
