Calculation of Carbon Emissions throughout the Lifecycle of Buildings Based on BIM Technology

This paper comprehensively discusses the carbon emissions of steel structures and the application of Building Information Modeling (BIM) in the construction industry. Carbon emissions from steel structures are crucial for global climate change and sustainable development. BIM models utilize computer technology to manage architectural information, playing a significant role in both design and construction phases. Life Cycle Assessment (LCA) is a systematic approach to evaluating the environmental impacts of products, processes, or activities throughout their entire lifecycle, providing scientific basis for environmental management. By integrating BIM models with LCA methodology, it is possible to achieve more efficient and environmentally friendly energy utilization and emission reduction goals, thereby driving the construction industry towards a more sustainable direction.
