At 20:00 on April 20, 2022, the 359th lecture of the "Hong" Lecture Hall, hosted by the Graduate School/Graduate Work Department, undertaken by the School of Architecture, and co-organized by the Graduate Science and Technology Association of the school, was successfully held in the form of an online lecture. Zheng Fang, professor, doctoral supervisor, and national first-class registered architect, School of Architecture and Art, Beijing Jiaotong University, delivered a report titled "Designing a Sustainable Future: Beijing 2022 Winter Olympics Venues", chaired by Liu Qibo, Deputy Dean of the School of Architecture, Chang'an University More than 400 teachers and students from relevant colleges attended the lecture. The following are the wonderful views and content in the theme sharing:
This report mainly consists of the following four parts: (1) Olympic sustainable and carbon neutral strategy (2) Overview of venues in the three competition areas / Ice venues and technology Winter Olympics (3) National Aquatics Center: the sustainable development of venues Sex (4) National Speed Skating Stadium: Sustainability of new stadiums.
1, Olympic sustainable and carbon neutral strategy
The International Olympic Committee's 2020+5 agenda mentioned that sustainable development is the theme of today's world, and sustainability has become one of the three pillars of the contemporary Olympic Games. The Sustainability Plan for the Beijing 2022 Winter Olympics and Paralympic Winter Games proposes the vision of "Sustainability, Towards the Future" and three goals: Smart City, Low-Carbon Society, and Olympic Model. The Beijing Winter Olympics have five key strategies to achieve carbon neutrality: low-carbon venues, renewable energy, low-carbon transportation, low-carbon ice production, and forestry compensation.
2, Overview of venues in the three competition areas / Ice venues and the Science and Technology Winter Olympics
The Beijing Winter Olympics are divided into three competition areas: Beijing, Zhangjiakou, and Yanqing, with a total of 36 venues. In the Zhangjiakou and Yanqing competition areas, the design concept of "Ecological Winter Olympics in Mountain and Forest Venues" runs through the design of the snow competition venues. In the Beijing competition area, renovation and New venues complement each other.
The Beijing Winter Olympics showed the world a wonderful technological Winter Olympics with the highest standard ice rink, sustainable post-competition scenes,light structure and smart construction, reduced environmental impact, and smart venues.
3, National Aquatics Center: Sustainability of Renovated Venues
The birth of the Water Cube of the National Aquatics Center is a process from natural objects to design, which incorporates the translation of mathematics and mechanics.
In the Beijing Winter Olympics, the National Swimming Center took on a new mission and completed the transformation from the Water Cube to the Ice Cube, becoming a venue for curling competitions. The detachable lightweight structure and the new ice-making process all reflect the technology and sustainable concepts of the Winter Olympics. In the future, the venue will also switch between the Water Cube and the Ice Cube according to demand.
4, National Speed Skating Stadium: Sustainability of new stadiums
The design concept of the National Speed Skating Stadium, also known as the Ice Ribbon, is derived from a sustainable strategy for ice stadiums, including 3 interrelated systematic goals: 1. Establish an intensive ice rink space to control the building volume and achieve energy-saving operation; ② Adopt high-performance steel cable structure, lightweight roof and curtain wall system to save materials; ③ Use renewable energy to reduce greenhouse gas emissions.
Ice Ribbon has overcome 10 key technical topics in design and construction: geometric construction, space and structure, facade and curtain wall, roof and ceiling, Olympic function and operation, fastest ice, grandstand, fire protection, renewable energy and wisdom The venue finally presents an efficient and sustainable venue.
After the presentation, Professor Zheng Fang interacted with the students. Then, as a special guest of this academic event, Professor Lu Shiliang from the School of Architecture of Harbin Institute of Technology had a warm exchange with Professor Zheng Fang. Finally, Hou Quanhua, Dean of the School of Architecture, Chang'an University, Liu Qibo, Associate Dean, and Associate Professor Liu Wei expressed their gratitude to Professor Zheng Fang for his wonderful sharing, and expressed their expectations for further exchanges with Professor Zheng Fang and the university in the future. Professor Zheng Fang presented his new book "Designing a Sustainable Future: From Water Cube to Ice Ribbon" to the School of Architecture, and the lecture ended successfully.
