A high level architecture framework for coupling building energy performance models

In this paper, a framework that couples energy modeling with building information models (BIM), building automation systems and occupancy data is developed using a distributed computing environment based on the principles defined in the High-Level Architecture (HLA) proposed by the US Department of Defense (DOD). The premise is that building stakeholders typically overlook opportunities to influence occupancy behavior because it is hard to measure its impact on energy use. Coupling energy simulation models to occupancy agent based models allows them to efficiently analyze feedback and other intervention strategies prior to actual dissemination to building occupants. These distinct and standalone models are referred to as federates in the coupled HLA environment. A case study example illustrates how the model coordinates time and data synchronization and transfer between federates the different federates.
