A standardized approach to BIM and energy simulation connection

Abstract : BIM (Building Information Model) applications cover many areas such as quality control, monitoring, structural analysis and space management. BIM is also widely used as a basis for energy simulation as it contains most of the data needed for energy analysis. However, buildings feature multi-physics phenomena in which energy is only one aspect; therefore it is often needed to jointly perform different kinds of simulations and, to properly connect BIM to the related simulation environments and formats. In line with this concern, our research work focuses on the issue of heterogeneous multi-models interoperability for simulation. The aim is to devise an approach and to develop tools that can support and enhance connections between BIM authoring tools and simulation tools, covering various physical dimensions. To implement this approach, we propose to rely on some well-proven and focused standards from the Building Smart International consortium, namely the IDM (Information Delivery Manual) and the Model Views Definition (MVD). In this respect, this paper brings two contributions. The first is an in-depth review and discussion of the interoperability issues of the Architecture, Engineering and Construction (AEC) area, in particular since the advent of BIM technologies. The second is an account of the first results of our research work, focusing on the definition and implementation of a well-structured and standards-compliant approach to the generation of energy simulation models from BIM IFC (Industry Foundation Classes) models. This work entailed defining a mapping between the building elements as defined in the targeted simulation engine (the simulation engine of the French thermal regulation), and the corresponding IFC elements and attributes. As the IFC do not cover all the required elements for energy simulation, further enrichment of the IFC – either through ad hoc extension or through connection to complementary data sources – was defined and implemented.
