Research on the carbon emission intensity and carbon reduction potential of prefabricated concrete structures
Abstrak
Prefabricated concrete structures (PCS), while recognized as a greener alternative to conventional cast-in-place methods, still entail significant resource and energy consumption. This study employs a life cycle assessment to quantify the carbon emission intensity and reduction potential of a typical PCS. The results indicate a total lifecycle carbon emission intensity of 1135.22 kgCO2e/m2, with the material production stage being the largest contributor at 419.13 kgCO2e/m2. Scenario analysis reveals that promoting green building materials, such as recycled steel and concrete, can achieve a maximum emission reduction of 11.12 % during the construction process. Under an optimistic scenario, this translates to a cumulative reduction potential of 94.33 million tCO2e in Shenzhen from 2025 to 2035. These findings provide a critical quantitative benchmark and a viable pathway for decarbonizing the building sector, offering valuable insights for policymakers and stakeholders in promoting prefabricated construction.
