</font><span style="color:rgb(31,73,125)"><font face="Calibri"><font size="3">You are correct <span style> </span>in the <span style> </span>section G 3.1.2.1 it is specified as that <span style> </span>Base case system efficiencies are inclusive of
the indoor fan power. </font></font></span></p><p><font size="3" face="Times New Roman">
</font><span style="color:rgb(31,73,125)"><font face="Calibri"><font size="3"><span style> </span>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.

</font><span style="color:rgb(31,73,125)"><font face="Calibri"><font size="3">If the above case is not true then <span style> </span>you can follow the <span style> </span>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 calculated as per the
Table-G3.1.2.9</font></font></span></div><div><span style="color:rgb(31,73,125)"><font face="Calibri"><font size="3"></font></font></span> </div><div><span style="color:rgb(31,73,125)"><font face="Calibri"><font size="3">Hope this helps</font></font></span></div>
