An industry foundation class based building product model of University College Cork's "to be constructed" Environmental Research Institute will be developed. This paper discusses combining such a building product model with a building management system and other tools and technologies to create a framework for monitoring, analysing and controlling a building throughout, its building lifecycle based on a set of performance metrics. The framework will be known as the building energy monitoring, analysing and controlling (BEMAC) framework. Current building performance assessment practices lack standardisation/continuity throughout the building lifecycle. An environment such as the BEMAC framework described in this paper offers a means to achieving such standardisation/continuity by documenting and communicating performance metrics data such that these data can provide value across the complete lifecycle of a building project, from planning through design and construction into occupancy and operation.
