BIM Architecture: White Egrets Fly Together Wetland Exhibition Wings at Bohai University Sports Center by CAS Architectural Design Institute

Bohai University of Science and Technology Gymnasium

The Bohai University of Science and Technology – Weiqiao Guoke Advanced Technology Research Institute (Binzhou) is situated in Binzhou City, Shandong Province. The campus is divided into two zones, north and south, with the Qinhuang River National Wetland Park to the east, offering exceptional urban landscape resources.

The sports center cluster occupies the southeast side of the North Campus, directly opposite Qinhuanghe Park. The gymnasium faces the North Campus entrance, serving as a landmark along the campus’s north-south axis. As the main sports venue on campus, the gymnasium incorporates a competition hall, training hall, and swimming pool. Classified as a Grade B venue, it meets the standards for hosting national and provincial events. Adjacent to the east is a standard 400-meter sports stadium, surrounded by basketball and volleyball courts, collectively forming a vibrant “vitality island” focused on sports within the campus.

White Egret Exhibition Wings · A Dynamic Campus

The college building cluster at Bohai University of Science and Technology draws inspiration from traditional Chinese academies, preserving their cultural heritage. The buildings predominantly feature red brick facades. As a major public structure on campus, the sports architecture injects energy and futuristic technology, transforming traditional forms into a contemporary, dynamic space. This design creates a lively atmosphere, fostering vitality across the campus.

Located adjacent to the Qinhuang River National Wetland Park, the sports arena is envisioned not only as a campus landmark but also as a central landscape structure visible from the park. The architectural form employs volume subtraction to maintain integrity and sculptural appeal, expressing dynamism through diagonal elements.

Inspired by the white egrets inhabiting the wetland park, the façade is clad in silver-white honeycomb aluminum panels. A ribbon-like, gradient skin spirals around the venue, lending the gymnasium a light and graceful presence, as if floating over the wetlands. This design metaphorically reflects the egrets spreading their wings, flying low and circling, creating an aesthetically pleasing vision.

Ping Sai Multipurpose · Campus and Community Sharing

Campus sports buildings differ from professional venues by emphasizing teaching, fitness, and community engagement over pure competition. From the project’s inception, dual-purpose use during and after events was a key objective. This ensures the design meets high competition standards while supporting multifunctional, low-maintenance use for the university.

Positioned near the campus’s north entrance, the sports arena offers shared facilities for the city, complementing urban sports venues and promoting public fitness.

Functionally, the arena includes a competition hall, training hall, and swimming pool. The competition hall measures 40m by 70m, seats 3,000 people with 70% active seating, and features fixed seats on only one side. This layout supports versatile uses such as fitness, teaching, competitions, performances, lectures, and ceremonies while minimizing construction and maintenance costs.

A U-shaped side hall on the second floor acts as a transitional space, serving as a buffer during competitions and supporting exhibitions, activities, seminars, and teaching. Adjacent to the track and field, this hall also serves as a large “private room” for students to watch events indoors, acting as a campus viewpoint and a social “living room” after classes.

Unified Design and Layered Construction

The gymnasium is positioned west of the track and field area, designed as an integrated complex. The west stand is cleverly embedded within the gymnasium’s form, creating a cohesive structure. An overhanging canopy replaces traditional seating covers, providing shade and rain protection while visually grounding the gymnasium with the stands. This compact design reflects an efficient use of the limited campus space.

The sports complex integrates the competition hall, training hall, and swimming pool in a compact layout that prioritizes land conservation, material efficiency, and energy savings. The swimming and training halls are stacked vertically and aligned north-south alongside the main venue, sharing central equipment and support facilities.

Natural Light and Green Ecology

The design actively incorporates natural light through skylights integrated into the roof. These skylights are shaped as three-dimensional triangular pyramids, strategically angled based on light environment analysis to minimize glare. Natural light is channeled into the interior via roof sides, with 28 and 12 corner windows atop the main and training venues, respectively, providing excellent indoor lighting comfort. This approach is a key green design strategy for the project.

Set against the park’s water system backdrop, the skylight’s lattice design resembles sparkling waves and white egrets in flight, creating a visually rich and rhythmic fifth façade for the building.
