Hi all,

I am facing this error in my eplusout.err file after implementing Ideal Air Loads Zone HVAC measure from the BCL, which can be found here;

I ran the Ideal Air Loads Zone HVAC measure with both add_meters: True and add_meters: False as inputs, with the same error occurring.

* Severe * Invalid Output:Variable or Output:Meter Index Key Name =NODE XX

* ~~~ * For Output:Variable or Output:Meter = VARIABLE YY

* ~~~ * Entered in EnergyManagementSystem:Sensor=RES_DS_RES_ASHP_CENTRAL_HTG/CLG_AIR_SYSTEM...

* ~~~ * Unique Key Name not found.

* Fatal * Errors found in processing Energy Management System input. Preceding condition causes termination.

XX, YY indicate different/multiple nodes and output variables, respectively. (i.e., Node 22, Node 29, SYSTEM NODE HUMIDITY RATIO, SYSTEM NODE TEMPERATURE etc.)

I searched through my IDF and could not find an Output:EnergyManagementSystem object; maybe that is the cause of the fatal error?

Please advise! Thanks!

I would try searching for an energymanagementsystem:Sensor object, since that’s what is directly referenced in the error.

One thing to keep in mind is that the ideal air loads measure deletes zone equipment when it runs. So it may be that some stuff is getting stranded when that happens depending on what you have in the model. You may need to do some preemptive house cleaning to get an ideal air load run.
