Abstract
Data-driven green building design in BIM is challenged by the lack of a comprehensive data integration framework with the capabilities of building life-cycle performance data management and application. This paper proposes a performance integrated BIM (P-BIM) framework for building life cycle energy efficiency and environment optimization. A school building is presented as a case study to verify the P-BIM framework and the design optimization workflow established. The results show that the optimization can improve IEQ by 11.5% and reduce LCC by 36.8%. The influences of different envelope constructions on indoor environment, energy consumptions, and costs are also studied. The P-BIM framework and the optimization methodology built on it demonstrate that the methodology developed can expand the application scope of BIM and contribute to data-driven green building design. More application scenarios focusing on the stage of facility management and different sustainability performance will be conducted in P-BIM framework in future works.
