    Model View Definition for Advanced Building Energy Performance Simulation
    Recent demand for higher energy efficiency within the building sector has led to the use of Building Energy Performance Simulation (BEPS) tools. 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.

    Realizing openBIM: Development of a BIM Model View Definition for Advanced Building Energy Performance Simulation
    OpenBIM, by definition, uses open data models to allow collaborative work practices. Industry Foundation Classes (IFC) is an open source data model for sharing planning, design, construction, and facility management data across various applications used in the AECOO industry. IFC is therefore suitable for storing significant volumes of data required for advanced Building Energy Performance Simulation (BEPS). This comprehensive nature of the data model makes IFC the key technology for storage and distribution of data but requires extensive infrastructure for data management. The use of Model View Definition (MVD) methodology refines data management by enabling lean data management through process specific subsets of the IFC data model. This paper describes the development of an MVD for advanced BEPS.

    MVD based information exchange between BIM and building energy performance simulation
    The process of preparing building energy performance simulation (BEPS) models involves repetitive manual operations that often lead to data losses and errors. 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.
