The Modelica modelling language is becoming increasingly important in the BPS field. The International Energy Agency’s (IEA) Annex 60 project, “New Computational Tools for Building Performance Simulation”, coordinates the development of BPS in Modelica. However, data collection and model generation are time-consuming processes, often leading to uncertainty. One subtask of the Annex 60 project focuses on the use of Building Information Modelling (BIM) as basis for building performance simulation. This paper presents an open framework for automated Modelica model generation from a BIM data source. The project outcomes include open-source software tools and a Model View Definition (MVD) for IFC to BPS information exchange with Modelica.

As a result, BEPS model inputs can vary widely from this time consuming, non-standardised and subjective process. This paper proposes a standardised method of information exchange between Building Information Modelling (BIM) and BEPS tools using the Information Delivery Manual (IDM) and Model View Definition (MVD) methodologies. The methodology leverages a collection of use cases to initiate the identification of exchange requirements needed by BEPS tools. The IDM/MVD framework captures and translates exchange requirements into the Industry Foundation Classes (IFC) schema. The suggested approach aims to facilitate the transfer of information from IFC based BIM to either conventional or advanced BEPS tools (e.g. EnergyPlus and Modelica) through the development of a specific MVD that defines a subset of the IFC data model that deals with building energy performance simulation. By doing so, the potential of BIM-based simulation can be fully unlocked, and a reliable and consistent IFC subset is provided as an input for energy simulation software.

These powerful predictive tools enable investigation of environmental and energy performance for different design and retrofit design alternatives. However, integrating BEPS with Building Information Modelling (BIM) based building design tools still experiences limitations due to a lack of standardised methods of information exchange between these domains. As a result, this paper presents a Model View Definition (MVD) for advanced BEPS. In doing so this work enables a standardised exchange of data from BIM to BEPS tools, such as Modelica, using the Industry Foundation Classes (IFC) standard. The entire process becomes available through the open source software framework emerged from the IEA EBC Annex 60.

This problem is one of the many reasons why buildings operate inefficiently and tend to consume excessive amounts of energy. Building Information Modelling (BIM) is an emerging technology which addresses the management of information throughout the Building Life-Cycle (BLC). Industry Foundation Classes (IFC) is a non-proprietary data model of BIM that enables effective data integration over the BLC. IFC is a rich data model which may represent the entire building, however most applications are interested in a subset of this model. Hence, it is necessary to filter the information exchange between different applications and Model View Definitions (MVD) is the methodology to define such subsets. This paper presents the development of a MVD for environmental and energy performance assessment to support building managers during operation.

One of the main causes of inefficient operation is the lack of data integration and system interoperability inherent in the AEC/FM industry. In many cases, the assumptions and specifications defined during design are not transferred throughout the life-cycle of the building, and actual operation deviates from design intent. Building Information Modelling enables designers to create digital models of buildings. Theoretically, these models should be exchangeable between disciplines and over different life-cycle stages, but in practice the lack of information exchange protocols in the building performance area inhibits such exchanges. In order to improve building operation throughout the building life-cycle, this paper proposes a BIM-based performance evaluation framework to compare design intent with actual operation. The framework uses the IFC schema to facilitate the information exchange process for better qualification and validation of data.
