Revision history [back]

The name and likely the type of PVT needs to be entered somewhere for the model to be called. Since you are using outdoor air the likely place would be an outdoor air system as you see in the example file. Another place would be the ZoneHVAC:EnergyRecoveryVentilator except that this model is not allowed as an input (which would be a nice improvement to EnergyPlus). So your only option as I see it is to install an air loop and configure it as 100% outdoor air which would model exactly what you are doing now with just a little more work. In the outdoor air system equipment list, enter the type and names of the HX and PVT. And of course, remove the ZoneHVAC:EnergyRecoveryVentilator you are using now.

In the Energy+.idd file, this object is allowed to be referenced in the OA system or a branch or plant object, none of which you are currently using. The simplest thing to do is add a 100% OA system.
