BIM based Building Energy Efficiency Certification Support System

Objective information related to energy simulation is required in the stages of using energy performance program (ECO2) for evaluating the current building energy efficiency rating. However, if 2D drawings are used for evaluating building energy efficiency rating, required information extraction and input are done manually and work hour depends on user’s ability and information are sometimes omitted or errored, which leads to work inefficiency. If such problems are also considered in connection with the changes in design information management environment related to BIM’s extended application as mentioned earlier, problems caused by 2D-based can be solved. In this study, we defined the method of extracting and extractable informationfrom in BIM by analyzing the energy efficiency rating certification work status and related request information. In addition, we propose a method to create and manage information that is not present information in BIM but needs information to be managed by BIM. Also, We proposed a method to modify the BIM can use in the building energy efficiency class certification. Based on this, we developed a system to support the building energy efficiency class certification by using BIM. Through case study, we confirmed that the efficiency of building energy efficiency class certification using BIM is higher than that of existing method. This study is expected to minimize data omission and error in the creating process of input information required for building energy performance evaluation and improve the efficiency of building energy efficiency rating certification tasks by automatizing information input process.
