公共建筑运行外部输入能源结构及电气化降碳研究OA

Taking some public buildings in Beijing as samples,the study investigates and analyzes the overall composition of external input energy for the operation of public buildings.By considering the conditions of different climate zones,it points out the overall common characteristics of the current external input energy structure for the operation of public buildings in China.Based on these samples,a carbon emission accounting system for public buildings in Beijing is constructed and calculated.The impact of current electricity usage on carbon reduction is analyzed,and a quantitative comparative study is conducted using cooking electrification as an example.The critical carbon dioxide emission factor EF'2 for electricity is obtained.The results show that cooking electrification in the southwestern region of China has a carbon reduction effect,and it is expected that the electrification of the external input energy structure of public buildings in Beijing will also have a carbon reduction effect after 2032.
