As one of the Hong Kong International Airport's infrastructure projects, the 200-meter long Sky Bridge connecting Terminal 1 and the North Satellite Concourse will be the world's longest airside Bridge. Rising above 28-meter, the Sky Bridge can allow the largest passenger aircraft A380 to taxi underneath. Upon completion, the travelling time between the two terminal buildings can be greatly reduced.

Adoption of the glass-bottom floor at both ends of the Sky Bridge allows travellers to enjoy the spectacular views of the apron. Being a new landmark of the airport, its sustainable features and the provision of observation decks, catering outlets and relaxation facilities provide a unique airport experience for travellers. This magnificent addition will further promote HKIA to be one of the world's greenest airports.

Green Features

Site Aspects

  • Convenient public access to basic services and recreational facilities including nursey room and charging station
  • Optimize exterior lighting design which minimizes light pollution
  • Adequate mitigation measures during construction phase to minimize air, noise & water pollution

Materials Aspects

  • Use of timber products from sustainable source
  • Use of non-CFC based refrigerants and non-ozone depleting insulation materials
  • At least 60% of demolition and construction waste recycled and reused

Energy Use

  • Automatic speed reduction travellators will be installed to increase energy usage efficiency
  • All electrical appliances and installations will be certified energy efficient products

Water Use

  • Adopting low flow sanitary fittings including aerators and dual flush toilets
  • Installing water leakage detection system for the prevention of unnecessary water consumption
  • Saving of over 30% of annual water consumption and over 20% of annual effluent discharge

Indoor Environmental Quality

  • Incorporating considerate measures into the design; considering aspects including hygienic plumbing and drainage system, waste disposal facilities, indoor and outdoor sources of air pollution, background ventilation, thermal comfort, natural lighting and provision for access for the disabled

Innovations and Additions

  • Adoption of Electronic Project Management System Aconex for ease collaboration of involved parties and enhancing the project management efficiency
  • Adoption of Building Information Modelling System in the design and construction stage for enhancing and improving the coordination of project development
  • Incorporating the design of twin tanks in flushing and portable water systems for preserving the water

Story

Having pledged to make Hong Kong International Airport one of the world's greenest airports, the Airport Authority Hong Kong has strived to incorporate sustainable elements in the projects at the airport, including Sky Bridge project. To ensure a green development throughout the design and construction stages, the feasibility of implementing green building technologies and materials was investigated and evaluated at the early stage. The potential areas to be incorporated with sustainable designs and materials were reviewed and studied before the implementation stage.

The project team focused mainly on the use of sustainable construction materials and construction methods to reduce waste during construction stage. To minimise the disruption to the busy airport's operation, the construction of Sky Bridge at HKIA used prefabrication method, which adopted pre-assembling large modules and components off-site. The prefabricated steel segments were then transported to the HKIA and assembled on site to form the permanent structure of the bridge. This sustainable construction method can produce a final product with enhanced time and quality control, as well as minimised environmental impacts on adjacent buildings and ambience.

Use of environmental friendly materials is one of the green strategies in the project. For example, timber products used in the project are obtained from well-managed and certified sustainable forests to conserve the virgin forests.  A comprehensive waste management plan is implemented to recycle demolition and construction waste.  Climate friendly refrigerant R410A and other alternatives are employed for air conditioning units and insulation materials to replace ozone depleting materials.

Not only that the design of Sky Bridge optimizing the indoor environmental conditions with adequate air ventilation, lighting, thermal comfort, as well as minimizing noise and air pollutants, it also enhances passengers' airport experience by saving 50% of travel time between the two buildings compared to the use of shuttle bus; and offering the view of Hong Kong International Airport to passengers to enjoy.  The green design can increase the well-being of airport users and take a leap forward for the sustainability development of HKIA.
