I submitted this earlier and was asked to add the .INP files to the .PD2 files I attached. Below is the original message repeated.
I'm doing a rough energy model using mostly Equest defaults and wanted to replace the existing baseboard electric heating with a heat pump. The resulting space heating increased from 57,000 kWh to 147,000 kWh (including the HP Supp.). From the baseline model I went into the wizard and added the dx heating and cooling and aligned the EER/COP with state compliant levels (10.7/3.2). Attached are the .PD2 files for baseline and HP models. Many thanks.

Yes, it is rough. Where does one begin? I generally like to look at
the results in the .SIM file. First look at the SV-A reports - one
model has no outside air, the other has 10000 cfm outdoor air.
Then look at the SS-D report. The one has a peak heating of 339
KBTU/hr and the other has 1200 KBTU/hr. This could be due to adding
outdoor air to the other.
If I still don't have an inkling, I will add some hourly reports to
compare the total supply cfm vs outdoor air ratio at different hours
of the year. I didn't have to do that in this case.
And if all else fails, I would then ask for help from the egroup.
