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
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
