National Speed Skating Oval

The National Speed Skating Oval (The Ice Ribbon) is a speed skating arena which is the only new venue planned to be built on Beijing's Olympic Green for the Winter Olympics. It will host the 2021 World Single Distance Speed Skating Championships and the speed skating competitions at the 2022 Winter Olympics. It was built on the location of the former Olympic Green Hockey Field used for field hockey event and the Olympic Green Archery Field used for the archery event.
It will be able to accommodate 12,000 spectators (6,800 permanent and 5,200 temporary seats) according to the bid book. After the games it is foreseen to use it as a public skating venue and for ice hockey clubs.
It has been designed by an architectural firm Populous. Construction will begin mid-2017, and be completed in 2019; first competition will be held in 2020.
It has an area of 12,000 square meters, being the largest speed skating venue in Asia. The facade is highlighted by 22 "ice ribbon" with a length of 622 meters each. The second floor has a Temple of Heaven-inspired curved curtain wall system. The "ice ribbon" is made of BIPV photovoltaic power glass from Zhongshan Ruike New Energy Co. This power glass is specially designed for the appearance requirements of the speed skating hall, combined with the metal color coating process, and a high-strength laminated structure to perfectly integrate into the building. It is a BIPV product that is truly born for architecture. Not only can it decorate the facade of the building like ordinary architectural glass, but it can also continuously generate electricity to provide long-lasting electricity for the building.
