On account of “double carbon” targeted regional public buildings in Beijing—Research on carbon emission measurement

Abstract

Energy conservation and carbon reduction in the construction field is an important part of China’s dual-carbon strategy. And construction operation Carbon emissions during the period. It is also the stage where carbon emissions account for the largest proportion of the whole life cycle of buildings, among which. The carbon emissions per unit area of public buildings are twice that of civil buildings. This study takes the sub-center of Beijing City as an example, focusing on “double carbon”. Under the goal, the research on the measurement of carbon emissions of public buildings within a radius of about 812 square kilometers in the sub-center, from the perspective of urban construction development and the overall carbon emissions of regional-level buildings, on the basis of the research on the actual operation data of urban buildings, the bottom-up carbon emission measurement method of the sub-center has been established, combined with research data analysis, during the operation period, the carbon emissions per unit area of public buildings are twice that of civil buildings. This finding highlights the key role of public buildings in the stage with the largest carbon emissions in the entire life cycle of buildings. In addition, our study also puts forward the characteristics and suggestions of carbon emission reduction of public buildings in the sub-center area, which are instructive for formulating targeted work suggestions on the “dual carbon” goals of urban development. This study not only focuses on the carbon emission measurement of individual buildings, but also expands the perspective to urban construction development and regional levels, filling the gap in the overall research on regional building carbon emission measurement in existing research. It also combines the latest building energy-saving design standards and green building ratings to conduct detailed measurement and analysis of the carbon emission levels of buildings with different energy-saving design standards.
