The full use of the heritage of the Summer Olympic venues is a major feature of the Beijing 2022 Winter Olympics.
Located along the west side of Chang'an Avenue, the Wukesong Sports Center was once the venue for the Beijing 2008 Olympic basketball competition.
In the Beijing 2022 Winter Olympics, the Wukesong Sports Center achieved an "ice basket conversion", and part of the women's ice hockey and men's ice hockey games of the Winter Olympics will be held here.
In addition, the Wukesong Sports Center has also built a new ice sports center as an ice hockey field. The ice sports center is called "Ice Linghua" because of its novel shape.
6 hours to achieve "ice basket conversion"
"The transformation of the original stadium is not a simple function conversion, but to retain the original use functions during the construction process, while injecting new winter sports use functions." Liu Yumin, director of the Planning and Construction Department of the Beijing Winter Olympics Organizing Committee, introduced, Beijing The 2022 Winter Olympics make the most of the venue's legacy from 2008.
The Wukesong Sports Center has a construction area of 63,000 square meters and can accommodate 18,000 people.
The stadium renovation project started in April 2020 and lasted 8 months. The renovation and completion of the year were realized.
After the renovation is completed, the Wukesong Sports Center uses the "ice dam" technology to "cut out" the ice rink and switch on the "ice dam" as needed. Converting the ice rink, the two game modes of basketball and ice hockey can complete the field conversion within 6 hours.
"In other words, the basketball league was still held the day before, and the venue can be converted into an ice competition venue on the same day. The operation capacity of the venue has been greatly improved, laying a solid foundation for post-match utilization. The Wukesong Sports Center has also become a sports venue. This is the first time in China that it is a general-purpose venue for hockey, short track speed skating, and figure skating," said Song Jiaye, deputy director of the Urban Venue Construction Office of the Beijing Major Project Construction Headquarters Office.
The renovation project of Wukesong Sports Center is based on the principles of green, sharing, and technological transformation and upgrading, and makes full use of new technologies, new concepts, and new materials to achieve a qualitative leap in energy conservation and consumption reduction, comprehensive and efficient utilization of venues, and competition viewing environment. .
The members of the ice hockey team of Tsinghua University participated in the "Meet in Beijing" Winter Olympics test event as athletes at the Wukesong Sports Center, and experienced various high-tech facilities in the Wukesong Stadium.
"The ice hockey can reach a speed of 100 miles per hour (about 160 kilometers) or more when it is hit. Many fans can't see how the ball is shot into the goal when watching the game live." Captain of the ice hockey team of Tsinghua University Wan Haoyuan said that in order to enhance the audience's viewing experience, Wukesong Sports Center introduced the "bullet time" special effect photography technology in this Winter Olympics. Training and referee penalties can allow viewers to see the shooting routes of athletes hitting the ball during live broadcasts.
"Ice Linghua" blooms five pine
Wukesong Ice Sports Center has a total of 2 ice rinks. During the Winter Olympics, Wukesong Ice Sports Center undertakes ice hockey training tasks.
Looking at the ice sports center from a distance, its outer curtain wall seems to be composed of countless pieces of falling snow. At night, the scene of the ice and snow world is presented in the change of light and shadow, so it is called "Ice Linghua".
According to Zhu Xiaodi, the designer of "Bing Linghua", the "Bing Linghua" building was designed with the combination of Chinese elements and modern sports spirit.
In order to present the scene of snow falling all over the sky at night, the outer curtain wall is designed with hidden lights to achieve the effect of "seeing the light but not the light".
At the same time, it also realizes precise control of each lamp to form a dynamic design of falling snow, depicting a poetic mood picture at night.
In addition to its beautiful appearance, "Ice Linghua" also widely adopts new technologies, taking into account the technical requirements of ultra-low energy consumption buildings and green buildings, and has become the world's largest ultra-low energy consumption sports building.
Feng Hui, the full-time deputy secretary of the Party Branch of the Wukesong Ice Sports Center Project of China Construction First Bureau, said that the Wukesong Ice Sports Center has two standard ice hockey fields, which is the first place in the Beijing 2022 Winter Olympics venue to use carbon dioxide transcritical direct It is one of the ice surfaces of the cold ice making system, and it is also the first ice hockey venue in China to use this technology to make ice, which is energy-saving and environmentally friendly.
"During the cooling process, the carbon dioxide refrigerant is directly sent to the site cooling coil for heat exchange, with good heat transfer performance and high heat exchange efficiency, which can save more than 40% of comprehensive energy consumption compared to traditional refrigeration systems." Feng Hui It is said that carbon dioxide ice-making has efficient total heat recovery capability. The unit can recover the waste heat of the ice-making unit while making ice, and directly produce hot water at 60 degrees Celsius to 65 degrees Celsius for heating in the hall. The waste heat recovery efficiency exceeds 75%. .
It is estimated that the venue can save about 3 million kWh of electricity every year, which is equivalent to saving 800 tons of standard coal and reducing carbon dioxide emissions by about 1,424 tons.
In addition, the ice rink adopts an advanced solution dehumidification system, which uses chemical methods to absorb and dry the moisture in the air.
Compared with the traditional dehumidification system, the solution dehumidification system can reduce the energy consumption by 50%, and the annual operating cost can be reduced by about 70%.
Sustainable use after the game
After the Winter Olympics, the Wukesong Ice Center will not only undertake major events, but also set up a youth sports club.
Mainly focus on ice hockey, figure skating, fitness, physical fitness, dance training, and extend the training to include yoga, sports rehabilitation, language and other projects.
"We will cooperate with surrounding schools, communities and government agencies to promote the popularization of ice and snow sports according to local conditions. By providing a full product line of services, more young people will feel the charm of ice and snow and experience the fun of ice and snow." Director Wang Shuxia said.
In the future, Wukesong Ice Sports Center will actively carry out various ice and snow events, take full advantage of the venue, and organize public events from time to time.
Meet the needs of many levels and diverse participation in ice sports, continue the public's enthusiasm for ice sports, and improve the efficiency of venue use.
Wang Shuxia introduced that ice and snow sports is a comprehensive project integrating entertainment, fitness, training, competitions and retail, forming a unique industrial ecosystem.
Wukesong Ice Sports Center will take advantage of the influence of the Winter Olympics and its own venue advantages to fully carry out projects including ice-making expansion, new venue construction, energy conservation and emission reduction in old venues, ice and snow entertainment, event services, and derivative product development. The upstream and downstream of the ice and snow industry chain are fully integrated, so that the ice and snow industry will continue to promote social and economic development after the Beijing 2022 Winter Olympics.
