The building energy consumption and carbon emission data measured in this report are the research data of the research group.
The Special Committee on building energy consumption and carbon emission data of China Building Energy Conservation Association has issued the Research Report on China’s building energy consumption every year since 2016.
Analysis on the change trend of energy consumption and carbon emission in the whole process of construction in China (2005-2019) the study found that, on the whole, the changes of energy consumption and carbon emission in the whole process of construction in China showed the same phased characteristics.
This year’s research report focuses on the assessment of the peak situation of building carbon emissions in various provinces and cities, develops a national unified provincial building carbon emission accounting method, analyzes the differences of provincial building carbon emissions and evaluates the peak situation of building carbon emissions in the future.
In 2021, the special committee was officially renamed the Special Committee on building energy consumption and carbon emission data of China Building Energy Conservation Association (Professional Committee of building energy and emissions, CaBee).
At present, the special committee has 13 member units, including Chongqing University, Beijing Architecture University, China Academy of Building Sciences, Shanghai Academy of Building Sciences, Shenzhen Academy of Building Sciences, Sichuan Academy of Building Sciences, Liaoning Academy of Building Sciences, Henan Academy of Building Sciences, Shaanxi Academy of Building Sciences, China Shuifa Xingye energy group Tongyuan design group, Yunnan Construction Technology Development Center, Tianjin building energy conservation promotion and training center, China Construction Group Technology Center, and Chongqing University are the chairman units.
Through years of research and accumulation, the special committee has established an accounting method system covering regional building energy consumption, building area and building carbon emission, constructed an assessment model of regional building carbon peak situation and state, a prediction method of carbon peak carbon neutralization scenario, and developed China building energy consumption and carbon emission database (www.cbeed.
It is subordinate to the branch of China Building Energy Conservation Association.
Note: 1) the building energy consumption in this report is calculated according to the coal consumption for power generation; 2) The total national carbon emission in this report is 9.877 billion tons, which is quoted from IEA database; 3) The calculation boundary of building material production energy consumption and carbon emission selected in this report is the building material production energy consumption and carbon emission consumed by the construction industry in that year.
02 data analysis of energy consumption and carbon emission in the whole process of construction in 2019 this report updates the data of building energy consumption and carbon emission in various provinces and cities in 2019 based on the calculation methods of previous years.
From 2005 to 2019, the carbon emission in the whole process of construction in China increased from 2234 million tons in 2005 Tons of carbon dioxide, rising to 4.997 billion tons of carbon dioxide in 2019, expanding 2.24 times, with an average annual growth of 5.92%.
2021.12.
It is found that the total energy consumption in the whole process of construction in 2019 is 2.233 billion tons of standard coal.
The special committee is a social group composed of relevant units and professionals committed to the accounting, research and application of building energy consumption and carbon emission data in China.
Figure 2021 Research Report on China’s building energy consumption and carbon emission: provincial building carbon peak situation assessment 01 introduction to the work of the Special Committee on building energy consumption and carbon emission data, China Building Energy Conservation Association (CaBee) organized and established a professional committee on energy consumption statistics in March 2016 to integrate industry forces, coordinate special research on building energy consumption and building carbon emission, and consolidate the data base of building energy conservation.
The purpose of the special committee is to And purpose: to build a data sharing platform for China’s building energy consumption and carbon emission, provide data support for the government to formulate policies, standards and plans, provide data sources for scientific research on building energy conservation, provide data value-added services for enterprises in the building energy conservation industry, and contribute to the development of building energy conservation and green building in China.
The themes of the reports over the years are: national building energy consumption measurement in 2016; In 2017, the building energy consumption was calculated by province; In 2018, construction carbon emission accounting; Scenario forecast of building carbon peak in 2019; In 2020, carbon emission accounting and carbon neutralization scenario prediction in the whole process of construction; In 2021, the situation of building carbon emission peaking in different provinces will be evaluated.
The 2021 Research Report on building energy consumption and carbon emission in China: assessment of the situation of provincial building carbon peaking is the sixth annual report issued by the special committee.
The research results of this phase mainly include the 2021 China building energy consumption and Carbon Emission Research Report, China building energy consumption and carbon emission database, and China building carbon emission visualization platform.
CN), Provide support for the carbon peak and carbon neutralization strategy in China’s construction field.
232021 Research Report on China’s building energy consumption and carbon emission: the results of the provincial building carbon peak situation assessment were released.
On December 23, 2021, China Building Energy Conservation Association and Chongqing University published the 2021 China building energy consumption and Carbon Emission Research Report: provincial building carbon peak situation assessment online.
03 analysis on the situation of building carbon peak at the provincial level in 2021, the state successively issued two documents: the opinions of the CPC Central Committee and the State Council on fully and accurately implementing the new development concept and doing a good job in carbon peak and carbon neutralization, and the notice of the State Council on Printing and distributing the action plan for carbon peak before 2030, making overall arrangements for carbon peak and carbon neutralization, Among them, it is required to “jointly formulate local peak reaching scheme”..
From 2005 to 2019, the energy consumption in the whole process of construction increased from 934 million tons of standard coal in 2005 to 2233 million tons of standard coal in 2019, an increase of 2.4 times, with an average annual growth of 6.3%.
In 2019, the total carbon emission of the whole process of construction in China was 4.997 billion tons of carbon dioxide, accounting for 49.97% of the national carbon emission.
The special committee is positioned as a public welfare and research-oriented organization.
