Hi,

I am trying to setup a Baseboard Heater in EnergyPlus using the code as follows:

ZoneHVAC:Baseboard:Convective:Electric,
  Zone A BASEBOARD,  !- Name
  Zone A Heating Availability Sch,  !- Availability Schedule Name
  HeatingDesignCapacity,   !- Heating Design Capacity Method
  5000,                    !- Heating Design Capacity {W}
  ,                        !- Heating Design Capacity Per Floor Area {W/m2}
  ,                        !- Fraction of Autosized Heating Design Capacity
  0.97;                    !- Efficiency

There are many outputs available for this class and I am interested in the output HVAC,Sum,Baseboard Electric Energy [J]. I checked my RDD file and it is available.

But, whenever I try to request this output, I get the following error:

The following Report Variables were requested but not generated -- check.rdd file
**   ~~~   ** Either the IDF did not contain these elements, the variable name is misspelled,

I checked everything but EPlus is still throwing that error. Please help to fix this.

Thank you for your time..

Can you post the actual IDF snippet for your Output:Variable? I bet that's the issue.

Hi @Julien

My Output code is as follows.

Output:Variable, Zone A, !- Key Value Baseboard Electric Energy, !- Variable Name Timestep; !- Reporting Frequency

Yeah so the the Key has to be the object's name, not the Zone it's in.

I suggest having Output:VariableDictionary in the IDF format so you can copy from the .RDD to your IDF file without error:

Output:VariableDictionary,
   IDF,                                    !- Key Field
   Unsorted;                               !- Sort Option

cf https://bigladdersoftware.com/epx/doc...

what you're looking for is either general:

Output:Variable,*,Baseboard Electric Energy,hourly;

or keyed:

Output:Variable,Zone A BASEBOARD,Baseboard Electric Energy,hourly;
