Method #1 won't work because the GSHP COP changes with indoor and outdoor conditions.
Method #2 could work, but there are nuances depending on HVAC sizing and setpoints. You could compare coil heat output variables, though there are also nuances there (e.g., duct losses). I think that's what we did to calculate the BEopt "delivered energy" outputs.
