ABSTRACT

Building energy consumption accounts for a significant proportion of global energy use, and reducing operational energy consumption in buildings has become one of the key pathways to achieving sustainable development goals. This study proposes a BIM-based building energy consumption simulation and optimization fr amework by integrating Building Information Modeling (BIM) technology with energy consumption simulation methods, aiming to enhance energy efficiency throughout the entire life cycle of buildings through digital means. The research first establishes data interfaces between BIM and energy simulation tools, enabling seamless transmission of building geometry, material properties, and operational parameters. Subsequently, a multi-ob jective optimization algorithm is introduced to achieve collaborative optimization of building envelope performance, equipment system configurations, and operational strategies. Finally, the effectiveness of this approach is validated through a real-world case study. Results indicate that the proposed method can significantly reduce building energy consumption during the design phase and provide decision-makers with scientific support. The innovation of this study lies in the deep integration of BIM technology with energy consumption simulation, constructing an integrated workflow while considering the dynamic characteristics of buildings across their entire life cycle. This method not only improves the accuracy of energy consumption prediction but also offers efficient technical support for green building design, making a positive contribution to promoting the low-carbon transformation of the construction industry.
