I was referring to Energy+.idd that comes with the EnergyPlus installation (should be at the same directory where EnergyPlus.exe is to run the simulation).
Per the IORef 422 (463 absolute), you can put negative numbers in the input fields "Design Level", "Watts per Zone Floor Area" and "Watts per Person" to denote loss.
Hope this helps.

I've tried "EquipmentLevel" input and that works. Where do I find the IDD? Is it a good idea to change this?
