E1, G standing for the first EnergyPlus scenario and GRDB respectively) and rooftop name.
s] standard deviation of GRDB is less than that of EnergyPlus in all no matter what condition the coil is in for all machines except the dry coil condition for A_7.
From the perspective of model sensitivity or robustness, the GRDB method has a big advantage over EnergyPlus because there is no alternative selection input in the generic method other than the manufacturer (e.
In terms of performance, the GRDB method has much higher accuracy and precision than Energy-Plus, and has a strong robustness against variations in inputs.
In terms of calculation demand, EnergyPlus is more time-consuming and cumbersome than the GRDB method.
