The accuracy of energy consumption calculations is often evaluated applying normalized variations of Equations (1) and (2): normalized signify bias error (nMBE) and coefficient of variation in root signify squared error (cvRMSE). Both equally the MBE and RMSE are normalized utilizing the signify on the measured values. The nMBE signifies the genera
