What are the highlights of the Beijing Winter Olympics?

Features 1: Maximize the use of the 2008 Olympic legacy.

Beijing 2022 Winter Olympics will make full use of the 2008 Olympic Games heritage, with a total of 14 heritages, including 10 for venues and 4 for land.

The heritage of the venue includes National Aquatics Center, National Gymnasium, Wukesong Sports Center and National Stadium. In terms of land heritage, for example, the National Speed Skating Hall used the land of two temporary venues of the 2008 Olympic Games-hockey field and archery field; The second phase of Beijing National Convention Center and Winter Olympic Village used the reserved land of the Olympic Park.

Feature 2: The ice rink adopts advanced refrigeration technology.

Beijing Winter Olympics will use 8 ice rinks, 10 ice rinks. Except for the original refrigeration system of the first figure skating training hall, all the nine ice rinks in the other seven venues use environmentally friendly refrigerants.

The National Speed Skating Hall, Capital Gymnasium, Shouti Short Track Speed Skating Training Hall and Wukesong Ice Hockey Training Hall are all equipped with carbon dioxide transcritical direct refrigeration systems. This system is the most advanced, environmentally friendly and energy-saving refrigeration technology in the world, which is the first time in the history of the Winter Olympics.

National Swimming Center, National Gymnasium and Wukesong Sports Center adopt traditional refrigeration system, and R449A is used as refrigerant.

Feature 3: Snow field inherits the concept of natural mountain forest.

Liu Yumin introduced that when choosing the site and designing the track, the ski resort should try to fit the original terrain, such as snowmobiles and sled centers. The track design has gone through five versions, and finally we chose the version that best fits the mountain.

For example, the maximum drop of "Xueruyi" platform is about 142 m, and the mountain drop we choose is just 140 m; The tracks of Genting Ski Park, National Cross-country Ski Center and National Biathlon Center basically fit the original mountain landform, which not only reduces the changes to the original landform, but also reduces the earthwork volume, saving the construction period and funds.

"In the process of building a snow field, we have taken many measures to respect the original natural environment and minimize the interference to the environment." Liu Yumin said.

Feature 4: All buildings meet the green building standards.

All newly-built indoor venues in Beijing Winter Olympics meet the three-star standard of green building, while other existing indoor venues meet the two-star standard of green building. Among them, the green Samsung standard can cover the international LEED gold medal standard.

"The Beijing Winter Olympics has also formulated the" Evaluation Criteria for Green Snow Sports Venues "for snow project research, which is an important legacy of Beijing 2022 and China's contribution to the international Olympic movement." Liu Yumin said.

Feature 5: All venues use green energy.

By the end of 2020, all venues of Beijing Winter Olympics will achieve 100% green power supply, that is, power will come from wind power generation or photovoltaic power generation. To this end, the Beijing Winter Olympics will be the first time in the history of the 100-year Olympic Games that all green and clean electricity will be used.

Feature 6: The construction of venues promotes the revival of industrial sites.

The construction of Beijing Winter Olympics venues has also promoted the overall revival of Shougang Park. Shougang has a history of 100 years. With the arrival of BOCOG office and the completion of ski jumping, the overall development of the park has been promoted.

Nowadays, Shougang Park has changed from an abandoned industrial park to a dynamic comprehensive park based on the protection and reuse of industrial heritage, integrating sports, culture and commercial tourism. It has also become the highlight of the protection and revival of the world's industrial heritage, setting an example for the integration of the Olympic Games and urban development.
