Calculation of Life Cycle Carbon Emissions of Residential Buildings

Abstract

Abstract The life cycle of a residential structure is separated into three stages: materialization, usage, and demolition, according to the life cycle theory of residential buildings. Materialization, use, and demolition computation models are built based on the features of residential building life cycle carbon emissions. The model is used to calculate and analyze the sensitivity of carbon emissions during the whole life cycle of the Qianluo 1# building. The results demonstrate that the total carbon output for the building over its entire life cycle is 155526 t, with 9006 t in the materialization stage, 145620 t in the use stage, and 900 t in the destruction stage. The sensitivity analysis results show that the heating carbon emission factor is the most sensitive and has the most significant potential for emission reduction, which is a critical factor in reducing residential building life cycle emissions.
