Hello, upon upgrading energyplus from 8.5 to 8.7 and running a jeplus project, I received the following error.

   ** Severe  ** ZoneCapacitanceMultiplier:ResearchSpecial="1.0" invalid Zone or ZoneList Name="1.0" not found.
   ** Severe  ** GetStagedDualSetpoint: Errors with invalid names in ZoneControl:Thermostat:StagedDualSetpoint objects.
   **   ~~~   ** ...These will not be read in.  Other errors may occur.
   **  Fatal  ** Errors getting Zone Control input data.  Preceding condition(s) cause termination.

I never crerated Zone="1" and not sure whether ZoneCapacitanceMultiplier is a feature of version 8.7. Any advice?

Two new input fields are added in ZoneCapacitanceMultiplier:ResearchSpecialobject in v8.7. Original v8.5 idf should be transitioned to v8.7 using IDFVersionUpdater in order for it to be able to run with v8.7. To address this specific problem, add two new fields a) a unique name for this object b) and leave zone or zone list input field blank.

@Chandan Sharma thanks, that solved it. I am now encountering issues with custom EMS code calculating comfort metrics, which appears less straight forward to fix
