OpenStudio attic model

In My model of a commercial building I created 8 thermal zones where 7 are rooms and 1 representing the attic. However, as the attic does not have any HVAC supplying conditioned air, I left it without any terminal unit supplying any air.

  1. In my simulation report I see Annual Energy GJ as Electricity:Zone:THERMAL ZONE 8 237.89 Electricity:Zone:THERMAL ZONE 1 46.85 Electricity:Zone:THERMAL ZONE 2 160.37 The TZ 8 does not have a terminal unit or any electrical equipment or any people schedule to it assigned. What is contributing to the total of 237.89 GJ as annual electricity. 2. My understanding is the HVAC electricity = Fans+Cooling+heating, However, is the VRF system electricity*COP=(Sum of thermal zone sensible cooling/heating) ? I have measured cooling delivered data and want to match with the model for verification. What variables will give the cooling delivered aggregate for daily/monthly/ yearly data. I am bit lost in the ENergyPlus output report nomenclatures.
