Innovative Roof Designs for Stadium

The Guangzhou University Central Stadium, accommodating 40,000 spectators with a 33,673 m² area, showcases unique roof designs tailored to its landscape. Designed for a basic wind pressure of 0.6 Kpa (112 km/h wind speed), the east and west stands feature distinct structures.  

The east stand is integrated into the hillside, with the architect’s concept of merging the stand into the mountain, creating a part of the hill. A green artificial turf-covered sandwich panel roof extends over the stadium, seamlessly blending with the landscape. The roof is supported by a suspension structure, transferring loads efficiently to the foundation.

The east stand, merging with a hillside, has a green artificial turf-covered sandwich panel roof (9500 m², 257 m span, 34 m cantilever). Using a suspension structure, it efficiently transfers load to the foundation.  

The west stand symbolizes "clouds over mountains" with a PTFE membrane roof (16,000 m², 300 m span, 60 m cantilever), supported by radial and circular trusses.

Bionic Conch Luxury Tent

Inspired by nature, bionic architecture honors natural aesthetics while promoting environmental harmony. The Bionic Conch Luxury Tent, designed to resemble the spiral form of marine life, integrates nature into modern architecture. This design reduces environmental impact and enhances the space’s eco-friendliness, creating a peaceful and immersive experience that connects guests to nature.

The Bionic Conch Luxury Tent offers a one-of-a-kind living experience. Its soft, curved structure maximizes space and stability while enhancing weather resistance. The thoughtfully designed interior ensures excellent lighting and ventilation, allowing guests to enjoy nature’s warmth and fresh air. With luxurious decor and modern amenities, it offers unmatched relaxation. Whether waking up to the sea breeze or sleeping under the stars, it provides a serene escape from the city’s hustle, bringing guests closer to nature.

The Conch-type luxury outdoor camping tent features a sturdy Q235 hot-dip galvanized steel frame combined with a double-layer membrane structure, both inside and outside. This design ensures privacy, provides great thermal insulation, and creates a cozy atmosphere. With a standard size of about 42 square meters, the eco-friendly tent is designed in a modern minimalist style with luxurious details.

The lightweight tensioned membrane is supported by a strong, shell-like framework. The structure has been thoroughly tested for stability and safety, able to withstand wind speeds of over Level 10. This makes it ideal for challenging locations like seaside areas or high mountains. The design is flexible and can be adapted to almost any shape or form.

BDiR offers luxurious and comfortable stretch tent accommodations, combining innovative design with practicality to create unforgettable outdoor experiences.

Efficient, Aesthetic, Sustainable, and Cost-Effective: The Future of Membrane Facades

    Membrane materials have increasingly been used for building facades, offering a range of benefits such as fast installation, low construction costs, and effective surface coverage that enhances both aesthetics and signage. As a result, mesh membrane materials are commonly found in commercial centers, cultural hubs, exhibition halls, and sports venues.

     One popular option is the use of perforated mesh membrane, which features a wider spacing between base fibers and a partial coating, resulting in a certain perforation rate (20–70%). This material has high transparency (30-70%), allowing natural light to penetrate while maintaining excellent shading and decorative effects. Alternatively, semi-transparent membranes can be used for different applications, offering a balance of light diffusion and energy efficiency.

Project Case 1: Germany Pavilion at Expo 2010, Shanghai
    The Germany Pavilion at the 2010 Shanghai Expo covered an area of 6,000 m². The facade was constructed using high-strength PTFE membrane with a Ferrari metal silver coating and 28% perforation. Approximately 21,000 m² of membrane material was stretched over the pavilion’s roof and surrounding walls. This membrane effectively blocked up to 80% of sunlight radiation, significantly reducing the building’s cooling load while allowing natural light to enter. As a result, the pavilion's energy efficiency was greatly improved.

Project Case 2: Germany Pavilion at Expo 2015, Milan
    At the Milan Expo 2015, the Germany Pavilion also utilized membrane structures as a key material in its design. This highlighted the growing recognition and use of flexible textile technology in architectural design, demonstrating its adaptability and sustainability for global expos.

Project Case 3: Xinhe R&D Design Center
    The Xinhe R&D Design Center, with a total building area of 61,000 m², features a semi-transparent membrane facade that allows 40% of light to pass through. The PTFE membrane is installed at a distance from the building, reducing sunlight intensity and providing ventilation during hot seasons, while still allowing for natural light inside. This innovative facade design ensures both energy efficiency and comfort for office spaces.
