The "Solar Decathlon Competition" is a construction and renewable energy technology competition for universities around the world. It aims to explore the use of new energy in buildings and promote the combination of building energy saving and new technologies. It is called the "World Expo" of solar energy. Since 2002, it has been successfully held for 15 sessions around the world, and was introduced to China for the first time in 2013.
The China Solar Decathlon Competition is hosted by the National Energy Administration of China and has been successfully held twice in 2013 and 2018. 10,000+ reports covered more than 3 million broadcast audiences, attracted more than 760,000 public visits, and received extensive attention from governments, media, universities and enterprises at all levels.
Beijing Jiaotong University ranked first in energy balance in 2013, first in energy performance and electric commuting in 2018, and fifth in overall performance. It has achieved impressive results in the previous two competitions.
2018年的成果还获得了可持续设计领域国际顶级大奖AH award 年度总冠军，是迄今为止中国项目获得的最高荣誉，在加拿大颁奖。
The 2018 results also won the AH award, the top international award in the field of sustainable design, the annual overall championship, which is the highest honor for a Chinese project so far, and was awarded in Canada.
The 3rd China International Solar Decathlon Competition will be held in Zhangjiakou City, Hebei Province from September to October 2021. As the debut project of the 2022 Winter Olympics in Zhangjiakou, the organizing committee will select 17 university teams from all over the world, design and build Zero energy consumption green energy-saving ecological house with both demonstration significance and promotion value.
In this competition, Beijing Jiaotong University joined forces with Mrs. Chen Zhang Mincong's Charity Fund, the British Architectural Research Institute Trust Fund and Loughborough University to form the international team Team BJTU+. The team is composed of 71 teachers and students from 8 colleges from BJTU.
In response to the global issue of "post-disaster rescue", the team will design a "sustainable emergency building": building a disaster preparedness space system that uses modules as units and can be flexibly combined. Optimize disaster relief models, improve energy and medical supply forms, and improve the comfort of living spaces.
At the same time, modular prefabricated industrialized buildings also serve the leisure, volunteer station, medical rescue and other buildings needed for the Winter Olympics, and have a broad market promotion space.
We focus on the needs of different stages after the disaster, develop different response strategies, and propose a set of BBBC (Bag + Box +Building + Community) emergency rescue shelters as an overall framework. Throughout the rescue cycle, we will make full use of solar energy and other natural resources to achieve the goal of energy saving, and improve the building design methods for sustainable emergency rescue. The design will implement a phased solution strategy to gradually realize the transition and improvement of residential housing after the disaster.
In the first 72 hours of emergency rescue, traffic and communication were blocked, materials were in short supply, and there was no large-scale mechanical assistance. We will adopt the bag strategy to solve the rapid rescue needs of the medical team, rescue team and disaster-stricken people. The bag will integrate necessary materials, instruments (or tools) and simple support and shelter materials for people to enclose a temporary space for rest.
The integrated box strategy is aimed at the reconstruction phase after 72 hours. In order to meet the requirements of transportation and rapid on-site construction in the complex environment after the disaster, we will select a lightweight structural frame and a rapid assembly enclosure system to integrate into the energy box, transport it to the site, and release the folded space in the box during use to meet emergency needs. The space needs of medical treatment, shelter and equipment for the disaster-affected people, while solving the privacy, safety and hygiene issues after the disaster. Solar panels will solve the energy needs of the shelter. In addition to the basic components, there are also some folding furniture to improve indoor living comfort.
In the post-disaster recovery phase, the transitional building (transitional building) continues the box energy box to expand the auxiliary space. Through modular expansion ideas, a variety of space combinations are formed, which further enhances the comfort and versatility of the space, and forms a more complete Community centers or family living spaces for medical and health care, residential rest, community activities, shared exchanges.
It can be regarded as a complete disaster backup network, and all "Bag", "Box", and "Building" can be regarded as an integral part of it. According to different circumstances, there will be more possibilities for rescue and recovery.
