Abstract

The construction sector’s carbon footprint demands urgent material innovation. Using Building Information Modeling (BIM) integrated with structural analysis, we conducted a comparative design study of basement ceiling beams (35,558 m2) in a Chinese residential project. Results indicate that 630-MPa high-strength reinforcing bars reduce steel consumption by 27.12% compared with conventional HRB400 bars, achieving comprehensive cost savings of 11.51% (¥528,948 or ¥14.87/m2). This material substitution reduces 349 tonnes of CO2 emissions and decreases upstream resource extraction by 320 tonnes of iron ore, 134 tonnes of standard coal, and 1,033 tonnes of water. While limited to a single case study, these findings suggest that 630-MPa reinforcement represents a promising technology for construction decarbonization that warrants further validation across diverse structural applications.
