Research on Carbon Emissions Measurement during Materialization Stage of Prefabricated Buildings: A Case Study of Urban Renewal Project in Guangzhou
Prefabricated buildings (PBs) play a significant role in improving the efficiency of carbon emission reduction and accelerating the goal of carbon neutrality in the construction industry. Based on the emission factor method, this study establishes a carbon emission calculation model for the materialization stage of PBs from three phases: production, transportation, and construction, and applies it to compute carbon emissions of a case study in Guangzhou, China. The results show that (1) the main contribution of carbon emissions in the materialization stage comes from the production of concrete and steel reinforcement, whose carbon emissions account for 42.43% and 41.04% of the total; (2) the carbon emissions of the production phase account for 94.63% of the total, and the carbon emissions of the transportation and construction phases are equivalent, a result consistent with traditional cast-in-place buildings; and (3) the carbon emission intensity of PBs is 435.34 kgCO2eq/m2 in the materialization stage, which is significantly lower than that of traditional cast-in-place buildings.
