Abstract

Building information modeling (BIM) can facilitate evaluation of the energy performance of a building from the early stages of a project. However, due to differences in how information is represented in BIM and building energy modeling (BEM), the exchange of data between the two tools is tedious and error prone. This paper presents research on leveraging open BIM standards for facilitating energy analysis BIM use. An extension was developed for OpenStudio that transforms building information models represented in Industry Foundation Classes (IFC) files into building energy analysis models in the OpenStudio data format. In the defined workflow, the model transformation is performed by a serializer that was developed using the open source BIMserver, while the OpenStudio extension transitions models between OpenStudio and BIMserver. The model transformation algorithm and its implementation in BIMserver were validated in a case study by comparing the actual energy demands of a building with the predicted energy demands of a simulation model that was created through the developed workflow.
