With the proposal of the"Dual-Carbon Goals"(realizing carbon peak before 2030 and carbon neutrality before 2060 in China),higher requirements are proposed for carbon emissions in the construction industry domestically,especially in residential buildings,which account for about 48%of the entire construction industry's carbon emissions.Research on carbon emissions from residential buildings has significant practical significance for achieving the"Dual-Carbon Goals",as well as for people's lives and social development.Based on survey data from residential communities in hot summer and warm winter regions,this study uses SPSS 25 to conduct partial correlation analysis and ridge regression analysis on carbon emission data,and establishes a regression model for carbon emissions during the operational phase of residential buildings in hot summer and warm winter regions.The results show that the difference between the average annual carbon emissions predicted by the regression equation and the actual measured values for the residential community households is 3.4%.The number of residents indoors has the greatest influence on carbon emissions during the operational phase of residential buildings in hot summer and warm winter regions,followed by the building area,while the building orientation has a relatively small influence on carbon emissions.Residential building carbon emissions are relatively lower during the transitional seasons;the hot summer is the peak period for carbon emissions in hot summer and warm winter regions.The research on the current state of carbon emissions in residential buildings in hot summer and warm winter regions provides design solutions and operational guidance for residential buildings in this area.Additionally,it serves as a reference for evaluating carbon emissions in residential buildings in this region.
