This paper demonstrates how to apply a standardized Building Information Model (BIM) specified in IFC (Industry Foundation Classes) for Building Performance Monitoring. It describes how the IFC meta model is used to implement a Data Warehouse (DW) solution allowing the management and analysis of ‘dynamic’ buildings’ performance data (compiled from sensors and meters) and ‘static’ descriptive data (product model). The consolidated data can then be shared in a structured way amongst different software applications, such as design software, energy simulation packages, building energy management tools, or facilities management software. This standardized BIM provides an integrated data repository which supports the analysis and management of building performance data. To ensure that the benefits from this data source are maximized, it is essential that such a BIM provides reliable storage, effective sharing, and efficient retrieval of information. The success of this integrated DW-environment is based on an open and transparent shared knowledge source to support common language, communication protocols and standards. By supporting the IFC-standard (ISO PAS 16739), it greatly reduces the risk of miscommunication and improves data quality. The research achievements presented in this paper build upon results associated with the EU-FP7 projects CAMPUS 21 and BaaS. The paper provides an overview of how bulk data compiled from two demonstration sites is managed and proposes a new approach on how the data should be structured within the DW based on the IFC standard. The study discusses the integration of a BIM solution with an IFC-compatible DW and outlines how existing BIM based IFC objects can be further enhanced through a synchronous relationship with an IFC structured DW. Finally this paper illustrates the capability of using the IFC standard for data mapping and implementation of an IFC-compatible DW. Information modeling scenarios are presented and their applicability is demonstrated.
