Simulating energyplus with the BCVTB interface

edit

Hello,

I have a openstudio model with 3 zones. We are using a python program to execute energyplus with the BCVTB interface. I got it to work on thermal zone 3 but not for thermal zone 1 and 2. I have the input variables defined in variables.cfg as:

<variable source="Ptolemy">
  <EnergyPlus schedule="Cooling TZ2 Setpoint Schedule"/>
</variable>
<variable source="Ptolemy">
  <EnergyPlus schedule="Heating TZ2 Setpoint Schedule"/>
</variable>

But when I run the execution I seem to get no load on the Air Loop for thermal zone 2. I have a plant loop for district heating and district cooling and then Air Loops thermal zone 2.

Could use some help with this.

The Osm and idf file can be found here: https://drive.google.com/file/d/1TM6L...
