Abstract: Energy performance gap is considered as one of the most significant issues associated with the assessment of energy consumption in the built environment. In order to narrow this gap, simulation approach for energy performance assessment are requires comprehensive calibration procedures. Calibrated energy performance models facilitate a baseline representation of existing building performance patterns, thus, further accuracy in diagnosis, operation and energy conservation measures (ECMs) become possible through the use of calibrated models. The present study presents an iterative approach for calibrating a building energy model using full year monitoring data. The methodology focuses on disclosing the steps in calibrating the simulation model and the relative sensitivities of the assumed and monitored parameters used in calibration. The magnitude of the alteration in different levels of calibrated simulation models are evaluated with Mean Bias Error (MBE) and Root Mean Square Error (RMSE) and the model accuracy is controlled through benchmarks defined by ASHRAE Guideline 14, International Performance Measurement and Verification Protocol (IPMVP) and Federal Energy Management Program (FEMP).
