Towards BIM-based Parametric Building Energy Performance Optimization

The demand for sustainable buildings with minimal environmental impact and efficient energy use is increasing. The most effective design decisions for sustainable design can be made in the early design phases, but appropriate tools to explore design alternatives and understand their impacts on building energy performance are not available at this stage of the project. The integration of Building Information Modeling (BIM) and parametric modeling is the new trend of building modeling, which can greatly benefit sustainable building design. This research introduces an innovative tool to facilitate integrated parametric BIM and to enhance its applications towards creative, sustainable building design through simulation and optimization. The created tool, Revit2GBSOpt, integrates parametric BIM and building energy performance simulation and enables designers to generate alternative options in BIM to explore the energy performance simulation results automatically. Finding the optimized solution, the BIM model will be updated.
