The energy used by the coils to condition outdoor air IS included in electricity consumption.
I am just saying that the outdoor air system's outdoor air load component is not always included in Zone/Sys Sensible Cooling Rate. If the coils are off and the air loop is on, then Zone/Sys Sensible Cooling Rate would include the outdoor air load.
Think of it this way. If the air loop is on, and outdoor air is entering the building, and the coil is off. Then at this time there is some outdoor air load and the report variable Zone/Sys Sensible Cooling Rate has some value. You then turn the coil on. The outdoor air load has not changed, but the Zone/Sys Sensible Cooling Rate does change.
Do you see the difference?
Sorry, I have a question here.
if Zone/Sys Sensible Cooling Rate does not include any outdoor air brought into the building and then conditioned by coils or heat recovery equipment, then it can be converted to the electricity consumption for cooling?

What does the load from the previous model represent (i.e., what are the components of that load)? Did that air loop supply outdoor air to the building? Was the outdoor air load included in the load from the previous model?
The Zone/Sys Sensible Cooling Rate is the delivered capacity to the zone. This does not include any outdoor air brought into the building and then conditioned by coils or heat recovery equipment.
Do you want to know the total coil cooling/heating load? Look to the coils for that information.

Hello,
I earlier asked a question about Cooling Load in E+ but I am yet to get any response.
I am trying to match cooling load from a developed model with that estimated by E+ but I am not sure which of the variables in E+ represent the cooling load. I am thinking the closer variable is the Zone/Sys Sensible Cooling Rate, because the room being modelled has no latent load. I have to be certain about this before proceeding. Please your contribution will be highly appreciated.
Thanks

Subject: Cooling Load in EnergyPlus
Dear All,
I am a new user of EnergyPlus. Please can somebody tell me which of the output variables in EnergyPlus represent cooling load. Awaiting your reply. Thanks,
Oluwaseyi
