ABOUT US

TIMELINE

The National Aquatics Center (AKA the Water Cube/Ice Cube) is an iconic venue first built for the 2008 Beijing Olympics and later revamped for the 2022 Beijing Winter Olympics. 

It is the only Olympic facility funded by compatriots from the Hong Kong Special Administrative Region, the Macao Special Administrative Region, Taiwan, and overseas Chinese. 

Hailed as one of the "New Architectural Wonders of China," it is one of Beijing's new representative structures.

Established in August 2007, Beijing National Aquatics Center Co., Ltd., a wholly-owned subsidiary of Beijing State-Owned Assets Management Co., Ltd., is responsible for the operation and management of the National Aquatics Center.

Following the guiding principle of "maintaining the operation of the Olympic venues well after the games" issued by the Beijing Municipal Committee of the Communist Party of China and the People's Government of Beijing Municipality, the Beijing National Aquatics Center Co., Ltd. aims to become "a world-class venue operation service provider." The team continuously explore how to make full use of the Olympic venue in a comprehensive, recycled, and sustainable manner to provide a Chinese solution for the reuse of the Olympic venues. In 2019, the company was awarded the annual "Sport and Sustainable Architecture" by the International Olympic Committee.

Since the opening of the National Aquatics Center after the games, it has continued to expand its business scope. It has since been converted to hold various sports events, tours, large-scale activities, market development projects, franchise events, a water park, and an ice rink. As of the end of 2020, the center had received 26 million tourists, hosted more than 1,600 events, and provided swimming services to about 2.6 million people.

Following the venue retrofit for the 2022 Beijing Winter Olympics, the National Aquatics Center has achieved a comprehensive upgrade of its operational capabilities based on the "water-to-ice conversion" project, and successfully held curling competitions in 2019 and 2021. The center, as a a venue of both 2008 and 2022 Olympic Games, will continue to serve as a model for reusing Olympic venues after the games and innovate and develop the Chinese solution for the provision of services for water and ice events.

The 2008 Beijing Olympic Games' icon venue-Water Cube, has transformed into "Ice Cube", which is the world's first Winter Olympic Stadium to create curling ice in a swimming pool.

In the Olympic and Paralympic Winter Games, "Water Cube" is set to serve as the curling venue.

The construction of the convertible structure of the Water Cube was completed on Aug. 1.

Following on from the completion of the major construction, the Water Cube will now finish the renovation of sports lighting, ice-making, and air-conditioning systems in the curling competition venues in October, and will hold the China Youth Curling Championship in December to debut.

With the convertible structure of the ice rink and the removable ice-making system, the venue in the future will have both water and ice functions.

After the ice-making equipment and ice layer are removed, the ice rink can be reduced to a swimming pool.

According to the plan, water sports will take place in spring, summer, and autumn, and ice sports will happen during winter.

After the renovation, the venue will receive an intelligent system upgrade as well. The new intelligence system will effectively monitor the changes in the thermal, humid and lighting environment in the competition hall.

It will ensure that under any heat load conditions, the arena can react to changes and provide dynamic heating throughout the indoor environment. For example, when the ice surface temperature of curling track reaches minus 8.5 C, the temperature above 1.5 m of ice surface remains at 10 C, the relative humidity does not exceed 30%, and the temperature in the stands is 16 C to 18 C.

The Water Cube has also carried out a research project on architectural acoustics of the curling hall, in which the most advanced building sound-absorbing materials will be used. Athletes who are more than 40 meters apart at both ends of the track can communicate clearly through shouting.

Underground in the South Square of the Water Cube, the Ice Cube ice sports center is under construction at the same time and is estimated to begin trial operation next May.

The Ice Cube ice sports center will not only provide a competition guarantee for the Olympic and Paralympic Winter Games but also is expected to be used by 100,000 ice sports enthusiasts after the Games. 

The "Experience Beijing" ice sports testing program came to a successful end on Saturday as Beijing 2022 welcomed its 300-day countdown. Events of six ice sports were staged in five Olympic venues in downtown Beijing during the 10-day tests.

With three of the venues being legacies of the 2008 Summer Games and advanced technologies in place, Beijing manifests its determination to host an environmentally-friendly Games that are also safe under COVID-19 scenarios through the testing program.

Transferable stadiums

How long does it take for a basketball court to be converted into an ice hockey rink?

The answer from the Wukesong Sports Center is -- six hours.

In six hours, the stadium that once witnessed Team US beat Spain for men's basketball gold in 2008 can set the stage for women's ice hockey competitions, with quick ice-making and adjustment in the dehumidification system.

"That's very good for the whole sustainability of the games and going forward," said William Freyr Huntingdon-Williams, a diplomat invited to watch a test game at the venue.

"Now the newest thing here, of course, is the new technology in ice-making, which we've been told is much more environmentally friendly, which we're very pleased," the first secretary and deputy head of mission at the Embassy of Iceland added.

Huntingdon-Williams is referring to using carbon dioxide instead of ozone layer-harming Freon as refrigerants in ice-making, which will reduce carbon emission equivalent to that of 3,900 cars a year, cutting the number to nearly zero.

The technology is also applied in the Capital Gymnasium, a 53-year-old venue renovated to host figure skating and short-track speed skating competitions. Both events' top skaters will compete on the same rink, but with different requirements of the ice surface.

According to Remy Boehler, head of the ice-making team, in preparation for the Beijing 2022 Winter Games, figure skaters need "softer" ice to better support jumps, while short track speed skaters favor harder ice for more speed.

With the two sports being contested only five hours and a half apart on Day 3 and taking turns to put on a show on the rest of the competition days as the latest Beijing 2022 schedule indicates, a smooth transition is essential to setting the stage for skating feasts.

"This is the only venue that has to switch between two sports in the middle of a day, which gives us huge stress during these testing events," said Ding Dong, head of the Capital Gymnasium venue operation team.

That's why the transition was conducted seven times in six days during the testing program to get fully prepared for the game-time scenario, and Boehler and his team only needed two hours to do so.

Also undergoing transformation was the National Aquatic Center, where Michael Phelps completed his eight-gold-winning epic back in 2008. The "Water Cube" was frozen into an "Ice Cube" for the first time in 2019 and later melted back in May 2020. In the past 10 days, it hosted test runs of curling events after the transferable rink was put up for curling events.

"Thanks to the Winter Games, the venue got its facility upgraded, and energy consumption lowered. Its new form will bring new income, and the cost of water-ice conversion is much lower than building a new venue," said Yang Qiyong, general manager of the venue.

Post-game utilization

Making stadiums transferrable is not only preparing for a successful Olympic Winter Games but also making sure they can satisfy people's different needs in different seasons.

Like Beijing 2008 did in leaving legacies for the city and the development of the sport across China, Beijing 2022 hopes to help fuel the passion for winter sports in the country and provide them with enough facilities to enjoy themselves.

As the only newly built ice sports venue in the Beijing competition zone, the National Speed Skating Oval boasts an ice surface of around 12,000 square meters. It can seat 12,000 spectators, making it the largest speed skating venue in Asia.

Apart from technology highlights, including using carbon dioxide in ice-making and precise controlling temperature and thickness of ice surfaces, the venue's multi-functionality also sets the example in post-game utilization.

Ma Jin, the design director of the ice-making project, told Xinhua that the ice in the oval had adopted a submodule control unit, dividing the ice surface into several areas and making ice according to varying standards.

During ordinary times, it can receive more than 2,000 citizens at the same time and be utilized for ice hockey, speed skating, figure skating, curling, and other ice sports at the same time.

"The purpose is to give full consideration to post-competition utilization and provide hardware support for mass fitness and to meet various needs," he said.

Similarly, the National Indoor Stadium features ice surfaces that can change size for standard ice hockey or figure skating field of play. In fact, the two surfaces were newly added to the 2008 gymnastics, trampoline, and handball venue for men's ice hockey competitions during Beijing 2022.

Hi-tech makes games safe and fun

Apart from Beijing's promise to host a "fantastic, extraordinary and excellent" Olympic Winter Games, "safe" is also a keyword as the COVID-19 pandemic is still ongoing. To ensure everyone involved is safe and provide the audience with the best possible watching experience, the organizers employed state-of-the-art technologies during the testing program.

Smart watch-like intelligent thermometers with chips inside are employed in the Wukesong Sports Center to monitor personnel's real-time body temperature. They can achieve preciseness of 0.05 degree Celsius and users can check their body temperature with taps on their phone.

In the National Indoor Stadium, with the help of 40 cameras and a 3D reconstruction of the visual, "free visual angle" technology allows spectators to choose their angle of watching matches. It also functions in refereeing and players and coaches reviewing the game.

There's also good news for broadcasters. With self-help obstacle avoidance navigation, they don't have to carry themselves heavy equipment thanks to logistics robots shuttling within the working area and canteen to transport items.

In fact, they don't need to bring them on-site in the first place. Cloud broadcast system enables them to edit, distribute and store all their materials remotely on the cloud and even live stream events with their program directors back in their own country.

Apart from that, journalists can interview athletes from a different room to avoid contact, and mix zones can also be set up remotely.

"We believe these technological innovations will bring Beijing 2022 to spectators all over the world in a more spectacular way," said Gao Bo from the media operations department of the BOCOG.

Technology drives Beijing 2022 towards green and safe

Xinhua2021-04-10

The "Experience Beijing" ice sports testing program came to a successful end on Saturday as Beijing 2022 welcomed its 300-day countdown. Events of six ice sports were staged in five Olympic venues in downtown Beijing during the 10-day tests.

With three of the venues being legacies of the 2008 Summer Games and advanced technologies in place, Beijing manifests its determination to host an environmentally-friendly Games that are also safe under COVID-19 scenarios through the testing program.
