According to Chang, the National Stadium, also known as the Bird's Nest, will hold the opening and closing ceremonies, while the National Aquatics Center, known as the Water Cube, will host curling matches after being rebranded the "Ice Cube."

The use of preexisting venues will greatly reduce the costs for 2022, showing China's adherence to the idea of sustainability as conveyed by "Olympic Agenda 2020." The Agenda 2020, approved in late 2017 by IOC, contains 40 proposals mainly around cutting bidding and organizing costs for hosts, which were echoed by three concepts: "athlete-centered, sustainable and economical" in Beijing's bidding report ahead of the Winter Games. Beijing 2022 will be the first Winter Games to fully benefit from the reforms from their very outset.

In terms of the newly-built National Speed Skating Oval, dubbed the "Ice Ribbon," it is the only permanent new ice-sports venue for the 2022 Winter Olympics in Beijing.

Chang added the designers have taken into consideration of the future use in advance and they would serve their functions after the Games.

In November, the Beijing 2022 Legacy Coordination Committee was set up in the hope of ensuring Beijing 2022's long-lasting benefits to the citizens of China. Beijing 2022 will utilize 26 competition and non-competition venues located in three clusters of downtown Beijing, Yanqing district and neighboring Zhangjiakou, Hebei province.

China's set about transforming an old steel mill owned by Shougang Group into facilities for the 2022 Games, demonstrating its sustainable approach to hosting the Games.
