Multi-physical Model Simulation and Interoperability through BIM/ IFC using COMETH Simulation Engine.

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 dimension; so there is often a need to perform multi-physical simulation and therefore to properly connect BIM to various simulation environments and formats. In line with this concern, our research work focuses on the issue of multi-models interoperability for simulation. The aim is to devise an approach and to develop some 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). This paper describes this ongoing work, focusing on its first step – applying the approach to BIM and energy simulation connection. This work is based on the simulation engine COMETH developed in CSTB and implements the IDM process promoted by buildingSMART. The process implied to define a mapping between the building elements as defined in the simulation engine, and the corresponding IFC (Industry Foundation Classes) elements and attributes. As the IFC does not cover all the required elements for energy simulation in COMETH, further enrichment of the IFC – either through ad hoc extension or through connection to complementary is needed.
