BPOpt: A framework for BIM-based performance optimization

- BIM-based performance optimization (BPOpt) framework is developed.
- Open-source Optimo is developed to serve as a multi-objective optimization engine.
- Optimo utilizes the visual programming method integrated with BIM for BPOpt.
- The performance of BPOpt is evaluated with a case study of a design project.
- BPOpt works on the top of a widely used BIM-platform for sustainable design.
