Output cannot be found in CSV

Hello Everyone! I am relatively new to Energyplus. I am trying to output PMV, PPD, illuminance at reference point, energy cost, and electricity (EUI) and gas (EUI).

However, it only outputs PMV, PPD, and electricity (EUI) in my csv even though I have created these settings for others in my file.

Can anybody help me with information on what I might be doing wrong? I am happy to share any additional information required.

Thanks

@Manny can you upload your model to Google Drive, Dropbox, etc. and then share a URL for others to download? That would help others provide better solutions.

Thank you for the suggestion Aaron. It is really appreciated.

This is the google drive link.

I will really appreciate any help as this is my first project so far.

Thank you.

@Manny it looks like you need to change the sharing settings in Google Drive if you want anyone with the link to access the files, right now I have to request your permission to view them.

Thank you for pointing that out Aaron. I have adjusted the link settings.

@Manny, there are 13 Output:Variable requests in the IDF you shared. But as a few are redundant entries, there are really only 10 unique requests:

Output:Variable,
    *,                       !- Key Value
    Zone Thermal Comfort Fanger Model PMV,  !- Variable Name
    hourly,                  !- Reporting Frequency
    Always On Discrete;      !- Schedule Name

Output:Variable,
    *,                       !- Key Value
    Zone Thermal Comfort Fanger Model PPD,  !- Variable Name
    hourly,                  !- Reporting Frequency
    Always On Discrete;      !- Schedule Name

Output:Variable,
    *,                       !- Key Value
    Zone Heating Electricity Energy,  !- Variable Name
    hourly,                  !- Reporting Frequency
    Always On Discrete;      !- Schedule Name

Output:Variable,
    *,                       !- Key Value
    Zone Cooling Electricity Energy,  !- Variable Name
    hourly,                  !- Reporting Frequency
    Always On Discrete;      !- Schedule Name

Output:Variable,
    *,                       !- Key Value
    InteriorLights:Electricity,  !- Variable Name
    hourly,                  !- Reporting Frequency
    Always On Discrete;      !- Schedule Name

Output:Variable,
    RefPoint_Center,         !- Key Value
    Daylighting Reference Point 1 Illuminance,  !- Variable Name
    Hourly,                  !- Reporting Frequency
    Always On Discrete;      !- Schedule Name

Output:Variable,
    *,                       !- Key Value
    Facility Total Purchased Electric Energy,  !- Variable Name
    hourly;                  !- Reporting Frequency

Output:Variable,
    *,                       !- Key Value
    Facility Total Purchased Gas Energy,  !- Variable Name
    hourly;                  !- Reporting Frequency

Output:Variable,
    *, Lights Electric Energy, Hourly;

Output:Variable,
    *, Zone Lights Illuminance at Reference Point, Hourly;

The IDF also hold 8 Output:Meter requests - some are also redundant (e.g. 3 separate "Electricity:Facility" requests). In the end, the following 4 variables/meters are successfully being reported in the eplusout.eso file:

  • Zone Thermal Comfort Fanger Model PMV
  • Zone Thermal Comfort Fanger Model PPD
  • Electricity:Facility
  • InteriorLights:Electricity

The reported "Electricity:Facility" and "InteriorLights:Electricity" are in fact Output:Meter instances - not Output:Variable instances. For instance, there are 2 "InteriorLights:Electricity" entries in the IDF:

  • 1x Output:Variable
  • 1x Output:Meter

In the end, it's the Output:Meter "InteriorLights:Electricity" that's being reported in the ESO file - not the Output:Variable of the same name. Search the eplusout.err file for remaining (failed) ones, e.g.:

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, or the
requested variable is an advanced output which requires
Output : Diagnostics, DisplayAdvancedReportVariables;
   ************* Key=*, VarName=ZONE HEATING ELECTRICITY ENERGY, Frequency=Hourly
   ************* Key=*, VarName=ZONE COOLING ELECTRICITY ENERGY, Frequency=Hourly
   etc.

Heating & Cooling: The single zone in the model ("Thermal Zone 1") is served by an IdealLoadsAirSystem. As such, there is neither electric heating nor electric cooling energy use in your model. With ideal loads, zone heating and cooling requirements are instead reported as District Heating and District Cooling (see "end uses" in the eplustbl.htm file). Search the generated eplusout.rdd file for:

  • Zone Ideal Loads Zone Total Heating Energy
  • Zone Ideal Loads Zone Total Cooling Energy

... probably pick these instead.


Daylighting: I simply replaced "RefPoint_Center" with an " * ". Now getting realistic numbers in the eplusout.eso file. The eplusout.err holds additional warnings on daylighting parameters - these should help in pinpointing underlying issues with your model vis-à-vis daylighting.


EDIT

Utility Costs: Hadn't taken a deeper dive on the Utility:Cost issues, as reported in the generated eplusout.err file ... (more)

Thank you so much, Denis. That fixed the problem and I now have outputs for lighting and HVAC. I really appreciate the help.

Also, thank you for also sharing more explanation on the ideal loads air system which I previously used. I will try to conduct the simulation with other systems to see the changes in results.

PS: I have not gotten outputs for energy cost and any suggestions on that will also be appreciated. Thanks

Glad this helped. BTW, if you found the initial answer satisfactory, it is customary to accept it by clicking on the checkmark. Helps others in the future.

Regarding energy costs, search the generated eplusout.err file for "UtilityCost:": there are quite a few warnings on invalid parameters found in the IDF. I suggest you first fix those. See EDIT at the end of my initial answer.

Thank you Denis, I have done that. I will work on the IDF again and check for the warnings.
