Calibration procedure of energy performance simulation model for a commercial building

Calibration with actual data has been considered as one of the most important and difficult part for the systematic energy audit procedure. The purpose of this paper is to develop a systematic method, "base load analysis approach" to calibrate the building energy performance model with actual monthly data. The calibration procedure has been visualized as a logical flow chart and demonstrated with 26-stories actual commercial building located in Seoul. The results indicated that the developed approach provided a reliable and accurate computer model for the annual building energy performance simulations.
