Towards the implementation of a 3D heat transfer analysis in dynamic-bim (dynamic building information modeling) workbench

Energy efficient building design demands a complete understanding of building envelope heat transfer along with airflow behavior. Although existing building energy modeling tools provide 2D heat transfer analysis, they fail to execute full-scale 3D heat transfer analysis and lack proper integration with Building Information Modeling BIM tools. This paper addresses these issues first by developing a BIM-integrated plugin tool to extract building geometry and material information from a 3D building model and then demonstrating a complete 3D heat transfer analysis along with grid generation. This paper discusses the preliminary research work in data extraction from Building Information Modeling (BIM) for performing 3D heat transfer in a seamless manner. This approach will help towards the implementation of a 3D heat transfer in Dynamic-BIM Workbench, an integrative, collaborative, and extensible environment. This Workbench enables integration of domain modeling, simulation, and visualization.
