Text

Any parameter not directly based on the physical building or its equipment represents a degree of freedom that can be used to calibrate the model against the facility’s utility bills. By varying these parameters, the same model can be calibrated to meet uncertainty targets in multiple ways, but for very different reasons. This lack of a unique calibration point can cause misleading results for the NMBE and CVRSME. Furthermore, resultant calibrations respond differently to changes in other parameters, which can lead to significantly divergent savings estimates. It is therefore very important that the modeler minimize calibration uncertainty, but that such calibration is also accomplished for the correct reasons. Model inputs should not be unreasonably altered simply to reduce NMBE or CVRSME.
