Aiming at the six stages of building material production and transportation, prefabricated component production and transportation, lifting of components, and on?site construction, the carbon emission prediction model of the whole process of prefabricated shear wall building construction is constructed. Based on a prefabricated shear wall project in Wuhan, the carbon emissions of prefabricated buildings and cast?in?place buildings are compared and analyzed. The carbon emissions of prefabricated buildings are calculated at each stage of construction, and the strategies and measures for carbon reduction of prefabricated buildings are proposed, which provide new ideas for energy saving and emission reduction of construction projects and can effectively promote further “ low carbon ” development of prefabricated buildings.
