As the global ecological environment continues to increase,the sustainability research of construction projects has become a research hotspot at home and abroad.In order to achieve sustainable development of the construction industry,research on fabricated buildings is essential.Prefabricated building construction is the key to prefabricated construction,so the study of the sustainability of prefabricated components requires more attention.This paper defines the ecological footprint types of prefabricated components,and constructs a pre-fabricated ecological footprint estimation model based on Process Life Cycle Assessment(PCLA),taking concrete prefabricated composite panels as an example.An ecological footprint benchmark for the sustainability of prefabricated building components is provided by a comprehensive estimate of the resources,energy,and extent of CO2 emissions from the prefabricated process life cycle.
