[BLDG-SIM] Changing Heat Pump COPs & EERs



All,
 
For a particular simulation, I would like to change the ground source heat pump cooling EER & heating COP to FEMP's 'Best Available' of 25.8 and 4.9 respectively, at standard conditions. 
 
May I avoid tampering with response curves and very simply just change the cooling/heating electric input ratios as follows:
 
 
EIRc = 1/(25.8/3.412) = 0.1322
EIRh = 1/4.9 = 0.2041
 
 
Or is this too simplistic?  Ah Sundays, perfect for the quiet introspective contemplation of energy studies...
 
Thanks
