Green Design

The green design features adopted when HKIA was first built form AAHK’s legacy of best practice and provide a strong foundation for continued leadership and innovation. The T1 Midfield Concourse (T1M) development project exemplified AAHK’s commitment to best practices and innovation in green building design. Its design has incorporated 35 key green initiatives covering various aspects, such as energy-saving measures, reduced water use and sustainable construction methods, to deliver an exemplary sustainable building. The T1M project won a Grand Award in “New Buildings: Completed Projects – Institutional Building” category at the Green Building Award 2016 and achieved a Final Gold rating under BEAM Plus.

Green Airport Design Strategy

In developing HKIA into a Three-Runway System (3RS) and planning other new developments, AAHK has established a Green Airport Design Strategy to ensure environmental and green design elements are consistently and systematically prioritised early in project development and implemented throughout subsequent works. AAHK also voluntarily pursues third-party green building certification for major developments at HKIA. Some examples are listed below:

Hong Kong Green Building Council's BEAM Plus

• T2 Concourse (T2C) and Air Traffic Control Tower – Provisional Platinum
• Terminal 2 (T2) Expansion Works – Provisional Platinum
• AsiaWorld-Expo Phase 2 Development – Provisional Platinum
• Sky Bridge – Final Platinum
• HKIA Tower Two – Final Gold
• Transit Mail Centre – Final Gold
• HKIA Ground Support Equipment Maintenance Facility – Provisional Gold
• T1M – Final Gold

Civil Engineering Environmental Quality Assessment and Award Scheme (CEEQUAL – now known as BREEAM Infrastructure)

• Whole Team Award - Excellent Rating for the Third Runway and Associated Works

The expanded Terminal 2 has been designed as an exemplary sustainable building and has attained a Provisional Platinum rating under BEAM Plus. Green design features adopted include:

• A combination of passive design strategies and low-energy active design techniques;
• Use of high energy-performance glazing, wall and roof materials on façades to provide improved thermal insulation;
• Installation of over 2,000 square metre of PV panels as part of the roof design to offset energy consumption; and
• Reuse of existing building structures wherever practicable.

Building on the achievements of the Green Airport Design Strategy for the 3RS and related projects at HKIA, AAHK has taken a further step by formulating an airport-wide Green Airport Design and Construction (GADC) Strategy. This strategy applies a consistent approach to embedding green design and sustainable construction considerations in both building and non-building infrastructure projects, as well as developments at HKIA implemented through partnership agreements with franchisees and other business partners. This strategy helps ensure a high importance on environmental and green design elements will be put at the project design and development stages. These elements will then be implemented in the subsequent works to minimise the environmental impact over the whole project life cycle.

The airport-wide GADC Strategy was first rolled out in July 2021 and formally adopted on 1 August 2023, following the completion of a two-year trial period.
