Conventional detailed building energy modeling tools have limited functionality in a real building modeling. Since a co-simulation modeling for more detailed building energy simulation is getting concerns along with enforced IoT data availability. This co-simulation environment could be applied model predictive building control, continuous commissioning in existing buildings, etc. Since BCVTB and Modelica are introduced in building energy modeling, many researches attempted to combine different building simulation tools and even with actual hardware. In this research, actual building is modeled with EnergyPlus and Modelica and model calibration and validation is implemented with BAS and AMI data that is measured from the building. Occupancy information is derived through LBNL simulator and lighting and equipment information is developed based on the occupancy schedule. AHU and VAV box are modeled in Modelica and then the results (sensible and latent energy of supply air) are passed through FMU into each zone in EnergyPlus. Validation results shows that good agreement according to ASHRAE Guideline 14 but irregular events are not predicted.
