summary:With increasing interest in sustainable design, the issue of energy-efficiency in the building design process is receiving ever more attention from designers and researchers. Greater access to building performance analysis results has led designers and researchers to increasingly address energy-efficiency concerns. However, the huge amount of performance analysis data that may be generated during the design process cannot easily be handled by traditional data analysis methods. The goal of this research is to develop a data-driven approach for the integrated design process, in order to help to improve the accuracy of performance analyses and also reduce the time required to complete such design iterations. We propose our method to include five step: 1) Requirement identification; 2) Building modelling; 3) Workflow implementation; 4) Simulation and data mining; 5) Evaluation and refinement. A case study demonstrates our data-driven workflowÕs ability to guide the design process with high precision. Our approach can also be extended and applied to discover useful patterns in the building design process.
