"Black Technology" Helps Build Green Winter Olympics

In the process of venue construction in the three major competition areas of the Winter Olympics, low-carbon environmental protection has become the main direction of development, and green has become the background of the construction of the Beijing Winter Olympics.

"Ice Ribbon" achieves the most environmentally friendly and lowest carbon ice surface. The National Speed Skating Oval "Ice Ribbon" is the first Winter Olympics speed skating venue in the world to adopt carbon dioxide transcritical direct cooling ice-making technology, which is the most advanced and environmentally friendly ice-making technology in the world at present, and the carbon emission value is close to zero, and the ice-making energy efficiency is greatly improved. It is understood that after the game, the ice surface can be cooled in different areas, and the temperature of each piece of ice can be controlled separately, so as to realize the "Simultaneous operation and different use" of the venue. Two key design schemes, the integrated design of the ice making system of the venue and the structural design of the ice board, have been patented.

Two-way conversion of winter and summer events into the standard of venues. Beijing Zone, the Beijing Olympic Winter Games makes extensive use of the 2008 Beijing Olympic venues to realize the two-way conversion of winter and summer events into the standard configuration of Beijing Zone venues. The National Aquatics Centre "Water Cube" is the venue for the swimming, diving and synchronized swimming events of the 2008 Olympic Games, and during the Beijing Olympic Winter Games in 2022, the "Water Cube" will be transformed into the "Ice Cube" to undertake the curling and wheelchair curling competitions.

"Water Cube" is transformed into "Ice Cube". In order to achieve the "Ice-water conversion", it is necessary to set up a curling track on the swimming pool, and add the ice function on the basis of maintaining the water function, that is, to build a convertible structure and install a removable ice-making system in the middle of the competition hall, and cooperate with the upgraded air conditioning and dehumidification system, which is the first time in the history of Winter Olympics.

Venues use 100% clean energy. As early as July 1, 2019, the first batch of seven Beijing Olympic Winter Games venues and supporting service facilities, such as the National Stadium (Bird's Nest) and the National Aquatics Centre (Water Cube), have officially used green electricity. Huang Hui, Director of Urban Venue Construction Department of Beijing Major Projects Office, said that with the world's first 500,000-volt Zhangbei flexible DC transmission and transformation project put into operation in June last year, green and clean electricity such as wind power and photovoltaic power from Zhangjiakou officially entered Beijing, and all venues will use 100% green electricity by 2022. In addition, the venues and facilities of the Beijing Olympic Winter Games will be used for a long time and sustainably after the Games, to achieve a win-win situation in terms of benefiting the people, sports, urban and regional development, and to build the Olympic sports industry chain.
