    Development of a Model View Definition for Environmental and Energy Performance Assessment
    Very often, building managers face the challenge of having to operate a building in the absence of the appropriate information about how it should function. 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.

    Requirements for a BIM-Based Life-Cycle Performance Evaluation Framework to Enable Optimum Building Operation
    (Eindhoven University of Technology, 2015-10-29) ; ;
    Buildings rarely perform as well in practice as anticipated during design, and often consume 20-30% more energy than necessary. 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.
