Abstract

This paper focuses on the application of low-carbon technologies throughout the entire lifecycle of prefabricated buildings. By analyzing the carbon emission characteristics in the design, production, construction, operation, and demolition stages, it comprehensively explores the low-carbon technology pathways at each stage. The study finds that compared with traditional cast-in-place buildings, prefabricated buildings reduce the carbon emission intensity per unit area over the entire lifecycle by 26.7%, and carbon emissions during the construction phase decrease by 38.8%; however, carbon emissions during the transportation phase increase by 138%. The operation phase accounts for the largest proportion of carbon emissions, reaching 69.8%, while the production phase of building materials accounts for 29.0%. The application of BIM technology reduces construction waste by 30% and carbon emissions by 15%, and photovoltaic building integration technology reduces annual carbon dioxide emissions by 11.9 tons. It is recommended to establish a three-dimensional linkage mechanism of ‘policy-technology-market,’ promote the integration of technologies such as modular design, green building materials, and intelligent operation and maintenance, achieve carbon reduction throughout the lifecycle of prefabricated buildings, and provide a practical path for the construction industry to reach carbon peaking and carbon neutrality.
