This study focused on the optimal design of adaptive building facade for achieving better energy performance. Iterative facade components design are studied between virtual and physical models with integrated tools of BIM, parametric design and sensor devices. The main objectives of this study are: (1) exploring systematic design process via the analysis of adaptive components in responsive facade design; (2) developing compliance checking system for green building regulations; (3) developing optimization system for adaptive facade design process. This paper demonstrated the integration of various digital design methods and concluded with the energy modelling results of a demo project unit for various facade component designs.
