The completion of Terminal 3B (T3B) at Chongqing Jiangbei International Airport represents a monumental milestone in aviation architecture. As the final major piece of the airport’s large-scale expansion, this project solidifies Chongqing’s status as a premier global transit hub. At the heart of this transformation is ZHA, delivering a masterclass in how cutting-edge design can gracefully manage unprecedented scale.
Scale Meets Efficiency: The Genius of the ‘X’ Plan
Designing for massive passenger volumes without sacrificing human comfort is the ultimate test of aviation architecture. ZHA met this challenge by designing the world’s largest satellite terminal for air-passenger traffic, built to accommodate 35 million passengers annually. This addition elevates the airport’s total capacity to 80 million travelers and 580,000 flights per year, supporting Chongqing’s rapid economic ascent.
To achieve this, ZHA utilized an innovative “X”-shaped radial floor plan. This layout optimizes operational efficiency through:
- Maximized Gate Capacity: Houses 71 aircraft gates and stands, dramatically increasing turnover rates.
- Flexible Pier Design: Each of the four piers features Class C and E aircraft stands, allowing for rapid gate allocation and adaptable airline operations.
- Streamlined Flow: Seamlessly connected to Terminal 3A via an underground metro, the radial layout minimizes walking distances for departures and transfers.
- Congestion Relief: Passenger circulation vertically separates arrival and departure flows to prevent bottlenecks during peak travel hours.
A Civic Landmark Rooted in Landscape
True to ZHA’s signature organic style, T3B is deeply reflective of its context. The terminal’s striking, undulating roofline mimics Chongqing’s dramatic topography of mountains and rivers. Rather than a sterile transit box, the building feels alive; the flowing roof incorporates strategically placed skylights that flood the deepest parts of the terminal with natural light, intuitively guiding passengers through the space. To soften the travel experience, ZHA also integrated outdoor terraces and scenic courtyards on the northern and southern wings.
Forward-Thinking Sustainability
Aviation architecture is shifting rapidly toward decarbonization, and ZHA is leading the charge. T3B is engineered to thrive responsibly within Chongqing’s humid subtropical climate through advanced eco-technologies:
- Zero-Carbon Heating: Utilizing a zero-carbon air heat source system paired with hybrid natural ventilation, the design completely eliminates the need for traditional boilers—saving an impressive 1.4 million cubic meters of natural gas annually.
- Smart Glazing: The facade features thermal dimming glazing that automatically adjusts to changing sunlight and temperature, offering optimal shading and reducing cooling loads.
- Local Sourcing: The physical structure prioritizes locally sourced materials, lowering the carbon footprint of the construction itself.
The Verdict: Through T3B, ZHA has redefined the expectations of modern airport design. They have proven that mega-scale infrastructure can be highly efficient, sustainable, and deeply aesthetic all at once.
