Title : Research on daylighting optimization of ice rinks for frugal hosting of the Asian Winter Games: A case study of the speed skating hall at Heilongjiang provincial ice sports center
Abstract:
In the post-COVID-19 Winter Olympics era, ice sports in China are developing vigorously. The 2025 Harbin Asian Winter Games, adhering to the concept of frugal hosting, puts forward higher requirements for energy conservation of venues. Refrigeration energy consumption accounts for over 50% of the total energy consumption in ice rinks, and skylight design directly affects solar energy capture and thermal balance. This study takes the Speed Skating Hall of Heilongjiang Provincial Ice Sports Center as the research object, focusing on the significant transformation of its skylight system—reduced from the original glass lighting belt of more than 2,000 square meters to over 400 square meters and replaced with thermal insulation aluminum-magnesium-manganese material.
Through a combination of on-site measurement and numerical simulation, sensors are deployed at key nodes in the transformed skylight area, side light-transmitting area, and ice surface to collect data on daylighting efficiency and solar radiation heat gain on typical winter and summer days. Additionally, based on the Radiance daylighting simulation and EnergyPlus light-thermal coupling model, the impact of reducing large-area lighting belts on natural light utilization and refrigeration and heating loads is emphatically quantified.
The intended conclusions are as follows: reducing the skylight area and using thermal insulation materials can effectively retain necessary natural light, significantly improve roof thermal insulation performance, and reduce heat loss; although top skylights dominate direct light utilization, reducing their area lowers the summer refrigeration load; side lighting maintains lighting uniformity through diffuse reflection and reduces the risk of glare. This transformation strategy, by balancing lighting needs and thermal insulation performance, effectively optimizes the net solar energy gain of the venue and provides key empirical basis for the green and low-carbon operation of Asian Winter Games venues.
