Hong Kong International Airport Midfield Concourse fully operates

Aedas as Architects

As a core part of the airport’s midfield expansion, the Midfield Concourse equips the Hong Kong International Airport (HKIA) with sufficient handling capacity to strengthen the city’s competitiveness as a leading regional and international aviation hub. This project also symbolises a major achievement for the Airport Authority Hong Kong (AAHK), poised to embark on their expansion to a three runway system.


Located to the west of Terminal 1 and between the two existing runways at the airport, the five-level concourse has a total floor area of 105,000m2 with ceiling heights comparable to those of Terminal 1. There are 20 aircraft parking stands, 19 of which are bridge-served, including two Code F stands that are wide enough to cater for the double-deck A380. Passengers are connected to Terminal 1 via an extended automated people mover (APM).


Building up to full operations with 230 flights per day, the concourse can handle an additional 10 million passengers a year. The Mott MacDonald and Arup joint venture has been working on the detailed design of this project since June 2010, providing full multidisciplinary design and construction support. Aedas is the architect for the joint venture and has also worked closely with OTC Ltd on the planning of the concourse.


The concourse’s timely opening demonstrates that a collaborative effort of client, contractor, lead design consultants and their sub-consultants, can bring about a successful outcome to a large capital works programme.


Design concept


The design of the Midfield Concourse architecturally respects and complements the existing Terminal 1 (T1), while incorporating the latest thinking in aviation, passenger expectation and sustainability.


Passengers will be able to experience HKIA’s latest ambience experience with more landscaping and fresher colours than ever before. At the APM concourse, passengers alighting the train are presented with an impressive 8m x 40m long blue cast glass wall by artist Graham Jones. On arrivals, a complementary 8m x 29m red cast glass wall welcomes passengers. They are part of a magical space which glows with light: adjacent big green walls with waterfalls reference the natural landscape of the Hong Kong New Territories.


The undulating single-span roof of the concourse adopts a diagonal truss structure with curving north-facing roof lights to bring natural light deep into the heart of the building. At the centre of the departures level sits the retail hub, flanked by the north and south halls. Passengers can look both ways towards all the boarding gates, visible beyond the retail stores and food outlets. It is this intuitive legibility that provides a comfortable setting for a relaxed shopping and dining experience.


Sustainability


To maximise efficiency and sustainability, we have introduced more than 35 green features, including low-energy lighting systems, high performance glazing panels, solar shading and north-facing skylights to maximise natural lighting while reducing solar heat gain and saving on air-conditioning.


The concourse adopts an environmentally responsive building form, with its roof shape and glazed facades optimised based on the building’s orientation. The roof has an asymmetrical cross section with a deep protective overhang to the west to minimise solar heat gain. As the concourse’s axis is offset from true north and south, the aspect of the skylights sit at a skew to the main orientation of the roof, to face north to maximise natural lighting.


Recycled water is used for water-cooled chillers of the air-conditioning system and seawater for flushing. More than 1,200m2 of solar panels are installed on the roof to harness renewable energy.


The project targets to become one of the first few buildings to receive the BEAM Plus Gold Rating from the Hong Kong Green Building Council.


Building Information Modelling (BIM)


The Midfield Concourse is AAHK’s first facility to be developed with BIM, enabling use of innovative 3D tools such as wind flow modelling, air traffic control sightline and walk through checks. These 3D tools and implementation of BIM facilitated the coordination of all disciplines in a synchronised manner, while preventing and resolving coordination clashes. The application of BIM on this project won Bentley’s Be Inspired BIM Awards 2011 and Autodesk’s Hong Kong BIM Awards 2013.

Midfield Concourse at Hong Kong International Airport

iGuzzini as Manufacturers

The recent project completed at the Hong Kong International Airport is one of the largest public works conducted in the city in recent years. It consists of an entirely new structure in the airport's central area to the west of Terminal 1 and includes a new lighting system. iGuzzini succeeded in taking part in this project by complying with its strict design requirements and, as a result, won a contract worth approximately 15 million Hong Kong dollars. The project ended up taking longer than expected and underwent a number of variations on the way. The most important of these involved exchanging traditional lamps for LEDs and installing sensors to integrate the preponderance of natural light with artificial illumination when needed. These variations were required in order to comply with the “Hong Kong Beam Plus” standard, a procedure introduced in 2010 for all buildings that includes the energy consumption of luminaires in the assessment of environmental performance. This standard has also affected other choices in the building's design, such as the special glass that has been used, which reflects 40% of solar radiation. This glass helps keep the building cooler and therefore its geothermal-based air conditioning system is used less and energy consumption is reduced. The airport authorities held a bid for the lighting system, that was won by a design put forward by the Arup studio, which succeeded in complying with the energy consumption limits specified by the client by exchanging traditional lamps for LEDs. The other strict requirement stipulated by the airport authorities was the total lack of glare as they insisted on maximum visual comfort.


The lighting project is based on the use of an innovative recessed luminaire that combines iGuzzini's optic expertise with Arup's innovative design skills. The recessed luminaire was designed, developed and industrially manufactured between the company's Italian headquarters and its branch in Hong Kong and is based on the standard Reflex recessed luminaire and the Palco spotlight. To obtain the results required by the customer, the Palco spotlight optic was amplified by up to 54°, thereby achieving an extremely high efficiency level and a UGR of < 10. The luminaire, therefore, has a high precision light effect with an efficiency level of 5000 lm/W, which means it can illuminate heights of up to 15 metres with a better level of visual comfort than that stipulated by the strict regulations for work environments with display screens. This impressive achievement was reached by combining the carefully tested technology of two different products to create the new hybrid Reflex Supercomfort device that boasts new features and performance levels. The luminaires have been installed in groups of 6 and 4, depending on the airport area and the relative quantity of light required. They are mounted on modular triangular metal structures and are fitted with adapters that allow them to be adjusted between 0° and 15° given that the ceiling is curved. This option of adjusting the angle of the optic compensates the inclination of the ceiling so the luminaires always appear to be vertical. Another product that has been customised for use at the airport is the iRoll luminaire. Designed by Bo Steiber, the device has a diameter of 180 mm and Palco optics. This luminaire is installed between the triangles in certain areas of the airport. Here, adapting the luminaire has been particularly complex as in some cases its height has been reduced to as little as 10 cm. Other luminaires, such as Woody and Front Light have also been used in this project, but 80% of the devices supplied are the specially customised Reflex and iRoll luminaires. This considerable production demand has meant that not only the company headquarters, but its branches have been involved in creating the lighting for this important new hub. All the devices installed feature DALI technology and are controlled by a non-iGuzzini control system. The project has already won a merit award in the 'Building currently under construction' category of the “Design Green Building Awards 2012 ", organised by the “Hong Kong Green Building Council” and the “Be inspired” prize at the BIM Awards 2011, in the “Innovations for Campus, Airports and Military Airports” category.
