五棵松冰上运动中心，北京/建筑设计

Wukesong ice sports center has a total construction area of 38960 ㎡, and can accommodate about 2500 spectators at most. The venue contains two standard ice rinks. It is the ice hockey training venue for the 2022 Beijing Winter Olympic Games.

总建筑面积约38960平方米，地下两层、地上两层。地下两层为冰场，设置南北两块60×30米和60×26米可转换场地和1907个固定座椅；地上两层为体育文化配套用房和一个910座的剧场。五棵松冰上运动中心拥有两块室内冰场，一块室外冰场，并同步建设看台及观众休息区、训练场辅助用房、设备机房、公共厅及交通空间等。

The total construction area is about 38960 square meters, with two floors underground and two floors above the ground. The two underground floors are ice rinks, with two 60 × 30m and 60 × 26m convertible field and 1907 fixed seats; The two floors above the ground are the supporting rooms for sports and culture and a 910 seat theater. Wukesong ice sports center has two indoor ice rinks and one outdoor ice rink. It also has grandstands, spectator rest areas, auxiliary rooms for the training ground, equipment rooms, public halls and traffic spaces.

2021年1月25日，五棵松冰上运动中心制冰完毕，并通过北京冬奥组委组织的专家验收，已具备运营条件，成为冬奥会首个具备运营条件的二氧化碳冰场。

On January 25, 2021, the ice making of Wukesong ice sports center was completed and passed the acceptance of experts organized by the Beijing Organizing Committee for the Winter Olympic Games. It has become the first carbon dioxide ice rink with operating conditions for the Winter Olympic Games.

中心采用的是和国家速滑馆相同的二氧化碳跨临界直接蒸发制冰技术，整个制冰系统换热效率更高，再搭配高性能的热回收系统，形成一套“绿色环保0排放”的制冰系统，使得本场馆完全符合国家承办冬奥会时承诺的切实践行绿色奥运理念。

The center adopts the same carbon dioxide transcritical direct evaporation ice making technology as the national speed skating hall. The whole ice making system has a higher heat exchange efficiency, coupled with a high-performance heat recovery system to form a set of "green, environment-friendly and zero emission" ice making system, so that the venue fully conforms to the national commitment to practice the concept of Green Olympics when hosting the Winter Olympics.

五棵松冰上运动中心是为响应国家冰雪发展战略、提升国家冰雪运动实力、服务2022年冬季奥运会、提升北京市青少年冰上运动培训水平的号召而建设。场馆融入世界先进的设计理念，力争建设奥运会级别冰球赛事的配套设施，以及国际标准的演艺舞美灯光系统。

Wukesong ice sports center is built to respond to the National Ice and snow development strategy, enhance the National Ice and snow sports strength, serve the 2022 Winter Olympic Games, and improve the ice sports training level of Beijing youth. The venue integrates the world's advanced design concepts, and strives to build the supporting facilities for the Olympic level ice hockey events, as well as the international standard performance and beauty lighting system.

五棵松冰上运动中心是单体面积最大的被动式超低能耗体育建筑，通过在建筑围护结构、能源和设备系统、照明、智能控制、可再生能源利用等方面综合选用各项节能技术进行集成，能耗水平远低于常规建筑。制冰技术采用的也是最节能环保的二氧化碳跨临界直冷制冰系统。

Wukesong ice sports center is a passive ultra-low energy consumption sports building with the largest single area. Through the integration of various energy-saving technologies in building envelope, energy and equipment system, lighting, intelligent control, renewable energy utilization, etc., the energy consumption level is far lower than that of conventional buildings. The most energy-saving and environment-friendly carbon dioxide transcritical direct cooling ice making system is adopted for ice making technology.

五棵松冰上运动中心优化工艺设计的被动式建筑幕墙、国内首个二氧化碳直冷跨临界制冰系统、溶液除湿系统三大技术，大大降低场馆能耗，每年可节约三百万度电，相当于节约标准煤八百吨，减少二氧化碳排放约一千四百吨。

The passive building curtain wall, the first carbon dioxide direct cooling transcritical ice making system in China, and the solution dehumidification system of the optimized process design of Wukesong ice sports center have greatly reduced the energy consumption of the venue, saving 3million kilowatt hours per year, equivalent to saving 800 tons of standard coal and about 1400 tons of carbon dioxide emissions.
