Green BIM-based building energy performance analysis

Abstract

ABSTRACTIn the face of a rapidly changing climate and global energy crisis, this study proposes the concept of green building information modeling (Green BIM), and suggests the use of a decision-making cycle when performing building performance analysis (BPA) to obtain design proposals with optimized environmental effectiveness in response to local climate conditions when BIM is used as a basic tool from the beginning of the design process.Taking building energy performance analysis as an example, in comparison with other domestic and foreign research, the important contributions of the study include: (1)Based on a design decision-making perspective, a Green BIM-based decision-making cycle can integrate the practical steps of BIM and BPA. (2) Furthermore, this study also finds that meteorological data in a format that can be used in BPA is not easy to obtain. Nevertheless, virtual weather station technology developed using cloud technology can enable a building project to obtain simulated meteorological d...
