Beijing Daxing International Airport ranks as one of the largest architectural projects completed in recent years.It stands out for its innovative design, which integrates advanced engineering techniques with functional details to ensure a seamless and sustainable travel experience. In this article, we will explore the main design features, structural engineering, sustainability strategies, and the airport’s economic and developmental significance. We will also provide a critical analysis through ArchUp’s perspective, along with frequently asked questions and a summary table.
Key Features of the Design
The airport’s design draws inspiration from traditional Chinese architecture, organizing interconnected spaces around a central courtyard. This courtyard serves as a focal point, guiding passengers toward different areas within the terminal, whether for arrivals, departures, or ground transportation.
The domed roof, one of the most prominent design elements, incorporates six structural forms that extend to the ground, providing full support while allowing natural light to illuminate the interior. This technique not only enhances visual aesthetics but also reduces the need for artificial lighting, thereby lowering energy consumption.
Structural Engineering and Advanced Technologies
The airport is one of the largest facilities in the world, spanning over 7.5 million square feet. To achieve this massive scale, engineers utilized a steel grid structure with over 170,000 components. The roof itself covers an area of approximately 350,000 square meters and features C-shaped columns directly connected to the roof for stability.
- Engineering Challenges:
The structural composition was meticulously studied, including load distribution, vertical support system responses, and structural deflection. Engineers considered 420 total load combinations and utilized 38 different cross-sectional sizes for the superstructure. - Future Flexibility:
Structural extensions reaching up to 100 meters allow for the reconfiguration of public spaces in the future, making the airport adaptable to anticipated growth.
Sustainability Strategies
Sustainable design was a core focus during the airport’s development. Several environmental elements were integrated to reduce energy consumption and improve efficiency:
- High-Performance Glass:
Helps minimize heat transfer and improves building insulation. - Natural Ventilation Systems:
Include fresh air inlets and return air ducts, reducing reliance on traditional cooling systems. - Roof Lighting:
Enhances energy performance and provides a more comfortable indoor environment for travelers.

Economic and Developmental Importance
Located in the Daxing district south of Beijing, the airport is part of a broader strategy to alleviate congestion at the existing capital airport. The project aims to enhance the national transport network and connect Beijing with key cities like Tianjin and Hebei Province.
- Capacity:
At its opening, the airport could accommodate 45 million passengers annually, with expectations to increase to 75 million in the coming years. - Transport Integration:
The airport includes a ground transportation hub offering direct connections to downtown Beijing, boosting regional economic development.
