Contribution of Beijing Winter Olympics low carbon action to emission reduction

It is reported that since September 2021, the low-carbon technology management team of Beijing University of technology has taken the lead and cooperated with 8 units, including the national speed skating hall, Tsinghua University, Beijing University of Aeronautics and Astronautics, Hefei Institute of material sciences of the Chinese Academy of Sciences, Shandong Guoshun Lvjian Technology Co., Ltd., Beijing Zhongchuang carbon investment Technology Co., Ltd., Beijing Green Exchange Co., Ltd. and Beijing aotemake Technology Co., Ltd., to focus on the above tasks and key problems, Jointly undertake the national key R & D plan science and technology Winter Olympics special project "key technologies and demonstration application of low-carbon Winter Olympics monitoring and carbon neutralization regulation".

Among them, the project team of Beijing Institute of technology independently designed and developed the "measure calculate control seek" technology system of carbon emission, successfully developed the Winter Olympic carbon measurement platform, integrated the human machine material environment data monitoring, carbon emission accounting, evaluation and control functions related to the Winter Olympic carbon emission, carried out the "carbon inventory", scientifically quantified the emission reduction contribution of various technologies, and realized the evaluation of carbon emission reduction actions of Beijing Winter Olympic Games, which has evidence, data and material evidence, The equipment developed by the project has been applied to the "ice ribbon" and the "ice cube" of the National Swimming Center.

Yu Biying, member of the project team of Beijing University of technology and deputy director of the energy and environmental policy research center of Beijing University of technology, introduced to the media, "We have installed intelligent monitoring equipment at dozens of points such as the grandstand area of the venue, energy consuming equipment and audience entrance to collect human-machine and physical environment data such as carbon dioxide concentration, flow of people, electricity, temperature and humidity of the venue in real time. This is' measurement '. The data is returned to the Winter Olympic carbon measurement platform to automatically calculate the carbon emission of each area of the venue, which is' calculation'."

At the same time, the "measure calculate control seek" technology system generates a Winter Olympic carbon emission control scheme library according to the data, quantifies the emission reduction effects of different categories and various carbon control measures, and puts forward carbon neutralization control schemes.

"Zero carbon cabin" outside the national speed skating Hall

On the west side of the "ice ribbon" of the national speed skating Museum, you can see a gray and white hut with a length of 6 meters and a height of 2.5 meters. On the top, there are two groups of strip-shaped wind leaves with red, blue and green blending and Winter Olympic color elements. This is the "zero carbon cabin" of the cooperation between Guoshun and beipolytechnic. Taking this as an example, Yu Biying said, "the roof fan and solar photovoltaic panel are used to supply clean energy to meet the power demand of indoor air conditioning, office equipment and large screen on the outer wall. Heat recovery system and electric energy storage system are installed to realize energy self-sufficiency and intelligent regulation and achieve zero carbon emission." the building itself also uses environmentally friendly and recyclable steel materials, and the cabin can be disassembled, moved and recycled.
