What does the water cube do when it becomes ice?

By building a convertible structure and installing a detachable ice-making system, "Water Cube" realized the reuse of converted materials and greatly reduced the cost of later demolition and reconstruction. When completed, "ice cube" will be put into use as a curling venue for the Winter Olympics. ?

Sun Weihua is the chief designer of the National Aquatics Center's "Ice-water Conversion". He participated in the initial design of the Water Cube, and now he is facing the task of "ice-water conversion" with his old colleagues. He admitted to the reporter that his mood was very complicated. ?

According to Sun Weihua, since its birth, "Water Cube" has fully considered the continuity of future architectural life, and realized the multi-functional operation requirements such as holding competitions, visiting, fitness and performing arts. However, the direct transformation from summer Olympic venues to winter Olympic venues is rare in the history of architecture. However, after communicating with the International Curling Federation and consulting a lot of information, Sun Weihua found that the two venues are similar, which greatly increased his confidence and that of the team members. ?

"First of all, in terms of the scale of the venue, a standard curling rink, such as a curling rink with four tracks and a standard swimming pool, has a certain degree of fit and is rectangular. So in terms of scale, the swimming pool is basically compatible with the size requirements of curling. Therefore, we believe that it is compatible with innate conditions first, which gives us great confidence. " Sun Weihua said.

The application of science and technology is a bright spot of this transformation:

In order to solve various problems in the process of "ice-water conversion", experts from Harbin Institute of Technology, China Research Institute and Tsinghua University have made technical breakthroughs, reformed the air conditioning, dehumidification and air supply systems, and planned to "informatize" and "intellectualize" the venues and upgrade the intelligent systems during the transformation. ?

"In this transformation of the Water Cube, we still pay special attention to its energy-saving and green transformation and upgrading measures. For example, energy conservation, we have taken a series of measures to achieve our energy-saving goals. First, we need some intelligent control. Its temperature, humidity, lighting and voice control system all need to be automatically adjusted through intelligent control. "

Sun Weihua also added that from the future to 2022, the design team will combine technologies or terminal products, apply technologies such as 5G, VR, AI, BIM, etc. in the venues, and even let spectators wear wearable devices, so that they can have a better experience while watching the games.
