Shanxi University Develops Methodology to Reduce Carbon Emissions in Building Life Cycle
A research team at Shanxi University has created a methodology integrating BIM and life cycle assessment to identify carbon emission reduction strategies in buildings. Their study, focusing on an office building in northern China, reveals that operational emissions, particularly from heating, dominate total emissions. The findings highlight the importance of early design choices in reducing long-term carbon footprints and emphasize the need for low-carbon heating technologies and efficient material usage to mitigate emissions.

Researchers at Shanxi University developed a methodology that integrates Building Information Modeling (BIM) with life cycle assessment to identify carbon emission reduction strategies in buildings. The study, which analyzed an office building in northern China, found that operational emissions, especially from heating, were the largest contributors to total emissions.
Steel production was identified as the primary source of carbon emissions during material production, while coal-based heating dominated operational emissions. Replacing coal with ground-source heat pumps could reduce heating emissions by over 50%. The methodology aims to enable architects to embed carbon assessment into design, emphasizing the importance of operational energy systems and low-carbon materials in achieving meaningful reductions in building lifecycle emissions.
