Leveraging building design model from energy performance model: From an IFC/BIM to cometh simulation engine

Conference of 14th Conference of International Building Performance Simulation Association, BS 2015 ; Conference Date: 7 December 2015 Through 9 December 2015; Conference Code:121832International audienceDynamic building energy simulation is recognized as a pivotal component of design tool support but is also considered as a complex task, requiring specific expertise. With the take up of Building Information Modelling and of advanced Information and Communication Technology (ICT) in the Architecture, Construction and Engineering (AEC) area, there is a unique opportunity to unfold the full potential of energy simulation thanks to seamless, effective a connection between BIM design information and energy simulation data models. In this scope, and with the aim to illustrate how BIM standardization may contribute to this challenge, this paper gives an account of a research study lead to deliver and assess a framework for automated transformation of Industry Foundation Classes (IFC) models to energy simulation models. The framework includes a well-defined transformation specification process, based on the buildingSMART Information Delivery Manual (IDM) and Model View Definition (MVD), and a software tool for the generation of input files for the French thermal regulation simulation engine (COMETH) from IFC models. The paper describes the overall framework, outlines the implementation of a simple use case of a house in passive mode, and draws some lessons for future works
