A study on carbon emission calculation of residential buildings based on whole life cycle evaluation

The whole life cycle carbon emission of buildings was calculated in this paper. Based on the whole life cycle evaluation theory, a carbon emission calculation model was established by using a single urban building as an example. The whole life cycle building of carbon emission calculation includes five stages: planning and design, building materials preparation, construction, operational maintenance, as well as dismantlement. It provides a reference for standardizing the calculation process of building carbon emissions by analyzed the carbon emissions and composition characteristics of each stage of the life cycle of the case house. The calculation results demonstrate that the carbon emission during the operational maintenance and building materials preparation stages in the whole life cycle of the building account for 78.05% and 20.59% respectively. These are the two stages with the greatest emission reduction potential
