Abstract

Abstract

Based on the characteristics of the construction process of prefabricated steel structures, a process-based construction carbon emission calculation method was proposed, and the feasibility of the method was verified in a case study of a multi-story steel-structured data center project. Through on-site measurement and investigation, the basic parameters of construction process-specific carbon emissions in 10 processes of floor deck, shear nails, steel rebars and concrete works were obtained. The calculation results were uniformly characterized as carbon emissions per square meter of floor area, and it showed that the total carbon emissions of steel structure floor construction were 0.759 5 kgCO₂/m² floor area, which was equivalent to 1.64% of the building material embodied carbon emissions of the floor construction. The carbon emission contribution was concrete works (0.477 8 kgCO₂/m² floor area), steel rebar works (0.181 5 kgCO₂/m² floor area), shear nail works (0.067 1 kgCO₂/m² floor area), and floor deck works (0.033 1 kgCO₂/m² floor area) in descending order. Among them, the carbon emissions by construction energy and material consumption accounted for 72.6% and 27.4%, respectively, and the generated direct, indirect, and embodied carbon emissions accounted for 62.9%, 9.7% and 27.4%, respectively. Based on the calculation method proposed by this study, the results obtained could show the main carbon emission sources, which was conducive to tracing the carbon emission hotspots of steel structure construction and formulating corresponding carbon reduction measures. In this case, the construction processes that generated carbon emissions more than 5% of total were the concrete mixing process, steel rebar lashing process, concrete pumping process, and shear nail welding process, which together generated 88.9% of the total carbon emissions of floor construction.
