Abstract
To study the carbon emissions of the external insulation walls of prefabricated residential buildings in cold regions,based on the full life cycle theory,the full life cycle of prefabricated concrete insulation exterior walls is divided into five stages:production,distribution,construction,operation and demolition.A carbon emission calculation model for the full life cycle of prefabricated concrete insulation exterior walls is established,and the carbon emission factor method is used to calculate its full life cycle carbon emissions.The results show that the carbon emissions from the production stage account for 90.28%of the total carbon emissions,while those from other stages together account for 9.72%.The production stage makes a significant contribution to the carbon emissions throughout the entire life cycle.Putting forward suggestions on energy-saving and emission reduction methods in the production stage is conducive to the transformation of the production of prefabricated concrete insulation exterior wall components in cold regions,achieving energy-saving and emission reduction in the construction industry,and contributing to the realization of the'double carbon'goals.关键词
