is specified as that Base case system efficiencies are inclusive of the indoor fan power. </span><o:p></o:p></p><p><span style='font-family:"Calibri","sans-serif";color:#1F497D'> But as per the G3.1.2.4 the supply and return fans shall operate continuously whenever spaces are occupied and shall be cycled to meet heating and cooling loads during un-occupied hours . if the supply fan is modelled as cycling and fan energy is included in the energy – efficiency rating of the equipment, fan energy shall not be modelled explicitly. </span><o:p></o:p></p><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:#1F497D'>If the above case is not true then you can follow the method specified in Alternative calculation manual(Ref attached image) to segregate the Fan power from the total EER if you know the combined EER at a particular dry bulb and wet bulb temperature(may be even at AHRI condition) having said that the fan power for all the fans has to be
