Session 6.11: Processes, Design, Tools and Methodologies in SBE (4) Evidence-Based Approach to Calibration of Whole Building Energy Model
A systematic procedure for calibrating building energy simulation models has been developed.The proposed method combines analysis of building plans and documentation manufacturers specifications,data from building sensors and results from EnergyPlus simulation.This paper describes the calibration method that was developed and demonstrates the use of the calibration procedure by applying it to an office building located in Kawasaki,Japan.Data collection took place between July 2015 and February 2016.Data from the months of August November and February were used as test data and used to determine the models CVRMSE and NMBE.These months were selected to be representative of summer,autumn and winter periods in Japan respectively.The remaining months were used for model training and to determine model inputs.This separation(training and testing data)was done to prevent bias when evaluation the model.Comparison of the simulation results with hourly measured data gave coefficient of variation of the root mean squared error(CVRMSE)values of 14%,11%and 11%for lighting,equipment and air handling units(AHUs)energy consumption respectively,all of which are below the 30%threshold set by ASHRAE Guideline 14(2002).In addition,the calibrated model also shows normalized mean bias error(NMBE)values less than 3%when compared with hourly lighting,equipment and AHUs energy consumption.
