Towards a context control model for simulation and optimization of energy performance in buildings

The process of optimizing building energy performance requires complex measurement, estimation and analysis. To address the complexity of designing for energy efficiency, models need to describe a building's different subsystems: The structure, processes, occupants, control equipment, etc. For example, a Building Information Model (BIM) describes a building's structure, while Business Process Models (BPM) can formalize processes going on in a building, and a Context Control Model (CCM) describes heterogeneous devices in relation to a building's context. To express the interdependencies between these subsystems an Enterprise Energy Performance Management Model (E-EPMM) is needed, integrating and extending the subsystems' models. In this paper we focus on the physical subsystem (the building and devices) presenting a Context Control Model for devices and appliances as an integral part of the E-EPMM. Further, we describe a middleware approach for instantiating and using th e CCM and its application in a multi-agent based energy performance simulation framework.
