The Beijing Winter Olympics are coming to an end.
As an important Winter Olympic heritage, the venues and facilities in the three major regions have left a deep impression on athletes from all over the world, and have also witnessed the birth of a series of new Olympic records and world records, making the simple, safe and wonderful Beijing Winter Olympics successfully held Laid a solid foundation.
The construction of venues and infrastructure has always been the top priority in the preparation of the Winter Olympics.
The high standards of the construction of the Beijing Winter Olympics venues have been fully affirmed by the International Olympic Committee. What is particularly valuable is that the legacy of the 2008 Summer Olympics can be used to the greatest extent possible without lowering the standards.
Some venues originally built for summer projects have achieved "gorgeous turn" through scientific transformation, which not only meets the needs of the Winter Olympics, but also has the "amphibious" ability to host winter and summer sports.
For example, the "Water Cube" of the National Aquatics Center realizes the conversion by the overhead structure in the swimming pool, and converts the original swimming pool area into a curling field, becoming a model of "ice-water conversion" venues.
It is not easy to renovate and utilize the old venues to make them meet the requirements of the event.
What is even more surprising is that the new competition venues for the Beijing Winter Olympics have also set a number of "world bests".
For example, the National Speed Skating Stadium adopts a hyperbolic saddle-shaped single-layer cable-net structure roof design, which is the largest single-layer two-way orthogonal saddle-shaped cable-net roof stadium in the world; the National Snowmobile Center is the world's first 360 The Shougang Ski Jump will become the world's first permanently reserved and used ski jump venue, becoming a professional sports competition and training venue.
In addition to considering meeting the requirements of the Winter Olympics competition project itself, the Beijing Winter Olympics also insists on using China's green building standards to guide venue construction.
For a long time, the LEED certification established and promoted by the U.S. Green Building Council is one of the most influential evaluation standards in the field of green building and sustainable building evaluation, but the committee has not developed evaluation standards for snow sports venues. There is also a blank in the international arena.
Adhering to the concept of "green Olympics", the Beijing Winter Olympics has formulated the "Evaluation Standard for Green Snow Sports Venues" for the research on snow sports, which is the first green evaluation standard applied to snow sports venues in the world. The construction provides technical support.
This important innovation in evaluation criteria was praised by the International Olympic Committee as "will leave a precious legacy for China and the Olympic Movement".
From compliance to leadership, from aligning with standards to setting standards, the Chinese plan for the construction of Olympic venues composed of Chinese design, Chinese technology, and Chinese manufacturing is Beijing's contribution to the Olympic movement and China's contribution to the world, and will remain in the century-old Olympic history. A strong stroke.
