Green and Low Carbon: “Give Priority to Passive Measures and Optimize Active Ones”
In response to the problem of high energy consumption in sports venues, the design adopts an energy-saving strategy of “giving priority to passive measures and optimizing active ones” to achieve the construction goals of low carbon, low energy consumption and low water consumption. A BIM model is built for design optimization. Ladybug is used to simulate the roof shape so that the sunshade coverage of the spectator stands can reach 100%. Xflow wind tunnel technology is applied to reduce the impact of airflows on the competition venue. Radiance is utilized to calculate and adjust the quantity, size and distribution of the roof light pipes, and the indoor natural daylighting rate is increased by 26%. Through calculation, the overall energy-saving rate reaches over 78%.

Post-game Operation: The concept of operation priority runs through from start to finish.
In response to issues such as vacancy and low utilization rate after games, the concept of operation priority is implemented throughout. In terms of spatial layout, “flexible reservation” and “composite adaptation” are adopted to cope with the differences in operation between normal times and game periods as well as the dynamic operation requirements. The atrium space between the stadium and the ecological platform forms a “flexible connection” to avoid mutual interference and resolve the differences between normal times and game periods. Meanwhile, a large number of flexible and dividable spaces are reserved. Partitioned by prefabricated lightweight ALC panels, these spaces can be converted according to specific needs to improve the utilization rate.
