Abstract：
Based on LCA(Life Cycle Assessment)theory,calculatedcarbon emissions of a residential building in Xinxiang. Results indicated that the carbon emissions was the largestin productionstage,accounted for 99.34%, which should be the focus of emission reduction.In operation stage used BIM technology to improve the orientation and glass materials, reduce 347?t carbon dioxide successfully.To prove that combined BIM technology with building carbon emissions,can reflect the carbon emissions immediately and adjust parameter in manufacture stage timly.
