Prediction error histograms of the five predictors constructed by utilizing the energy-consumingpattern: (a)hybridDBNmodel; (b)BPNN;(c)GRBFNN;(d)ELM;and(e)SVR. Then, in order to examine the superiority of the hybridmodel for the office building energy consumptionprediction, thefivepredictionmodelsarecomparedunder theconsiderationofdifferent data types (theoriginalandresidualdata).
