Weighing only half as much as a glass roof of equivalent area, the structure is nonetheless engineered to withstand high wind loads and pressure—combining the advantages of a lightweight build, high structural strength, and excellent light transmission. During the World Cup, the roof can be adjusted rapidly to accommodate Atlanta’s variable weather: when fully open, the stadium connects directly to the open sky, seamlessly blending the pitch with the urban horizon; when fully closed, it creates a completely enclosed environment, supported by a climate-control system that ensures the tournament can proceed regardless of external conditions. This dynamic, moving dome creates a visual spectacle, lending a unique architectural aesthetic to every World Cup match hosted within.

II. SoFi Stadium: A Futuristic Landmark for Sporting Events

Located in Los Angeles, USA, and completed in 2020, SoFi Stadium stands as one of the newest and most expensive premier venues for this World Cup. With a staggering $5.5 billion investment, it ranks among the world’s top sports complexes. The stadium seamlessly blends minimalist architectural aesthetics with cutting-edge membrane structure technology. Hosting eight high-profile matches—including group stage games, the Round of 16, and the quarterfinals—it serves as a core venue for the tournament.

The stadium’s most iconic feature is its fixed ETFE membrane roof. Eschewing traditional, heavy steel-structured roofing, it utilizes a lightweight, tensioned membrane system that offers exceptional light transmission. This allows natural light to diffuse evenly across every corner of the pitch, eliminating shadows and creating optimal lighting conditions for high-definition broadcasting and player performance. The fixed membrane roof incorporates a specialized ventilation design, ensuring efficient airflow without the need for a retractable mechanism—a solution perfectly suited to Los Angeles’s mild climate. Furthermore, the design significantly reduces the structure’s overall weight; combined with a sunken layout, it minimizes the visual dominance such a massive structure might otherwise exert on the city skyline, creating the impression of a dome hovering above the pitch. Inside, the stadium is equipped with a 360-degree, dual-sided 4K suspended giant screen and a comprehensive audiovisual system. Together with the natural illumination provided by the translucent membrane roof, these elements deliver an immersive viewing experience—a fusion of natural light and advanced technology—making it a world-class football arena that excels in aesthetics, innovation, and functionality.

III. AT&T Stadium: A Benchmark for Long-Span Sports Architecture

Located in Arlington (Dallas), Texas, AT&T Stadium is one of the largest membrane-structured sports venues in North America. Renowned for its massive, long-span retractable membrane roof and exceptional structural stability, it frequently hosts top-tier sporting events. As a key venue for the 2026 FIFA World Cup—jointly hosted by the United States, Canada, and Mexico—the stadium leverages its sophisticated membrane structural system and comprehensive event infrastructure to host high-intensity World Cup matches.

The venue features a long-span, retractable tensioned-membrane roof, composed of two colossal membrane panels. Supported by 64 high-precision drive motors and an arched truss structure, the roof can transition between fully open and fully closed positions in just 12 minutes, making it one of the most stable and largest-spanning retractable membrane roofs in the world. The membrane material offers wind resistance, waterproofing, thermal insulation, and noise reduction, enabling it to withstand the extreme weather fluctuations common in Dallas. When closed, it quickly creates a climate-controlled environment with stable temperature and humidity; when opened, it fully exposes the arena to the sky, restoring the authentic atmosphere of an open-air football match.

IV. NRG Stadium: A Model for All-Weather Event Spaces

Opened in 2002 in Houston, Texas, NRG Stadium was among the first NFL venues to implement a large-scale, lightweight retractable membrane roof. Following several rounds of upgrades and renovations—which significantly enhanced both its versatility for various events and its structural stability—the stadium was selected as a host venue for the 2026 FIFA World Cup. Its high-speed retractable roof and climate-controlled interior are perfectly suited to Houston’s hot and humid climate, ensuring an optimal environment for World Cup matches. The stadium’s retractable roof consists of a steel-hinged framework clad in a semi-translucent membrane. The roof is divided into two large sections that open toward the center of the arena. These sections are supported by massive trusses—each measuring 206 meters in length—which allow the roof to slide; when retracted, the roof panels are stowed above the stands at either end, while in the fully closed position, they completely cover the playing field. The entire opening and closing sequence takes just 7 minutes. Given the hot and humid summer climate in Houston, the membrane roof remains closed throughout all World Cup matches. The semi-translucent material filters out intense sunlight while allowing soft, natural light to permeate the interior. Complemented by a 2,500-ton central air-conditioning system, the stadium maintains a constant temperature of 24°C, significantly reducing the physical toll of the hot, humid weather on players and ensuring a high level of competitive play during intense football matches.

V. BC Place Stadium: A Landmark Stadium with a Retractable Cable-Supported Membrane Roof
