Research on the Influencing Factors of Carbon Emissions in the Construction Stage of Prefabricated Buildings

Prefabricated building is a significant way of energy saving and emissions reduction in the construction industry, especially in the construction stage. The existing research has different results on the calculation of carbon emissions in the construction stage of prefabricated building. In order to clarify the focus of carbon emissions measurement in the construction stage of prefabricated building, this paper conducts a meta-analysis of 65 Chinese cases to explore the key influencing factors and their internal relations. The results show that building size, building function, building structure form, level of prefabrication, urban comprehensive strength, urban coastal situation, urban population density, emissions sources considered, and life cycle phases considered will significantly affect the results of carbon emissions calculation. This study will provide a scientific and efficient basic theory for carbon emissions and emissions reduction strategies.
