I was wondering if there were any known issues regarding using JEplus and Energy Plus version 9.0.

I am running into an issue where my JE Plus project is validated and runs well, however is not compiling any results. I have narrowed the issue down to my version 9.0 projects only, as it has always worked very well for version 8.8. I have just verified this by running JEplus on a version 8.8 project and verifying the results are produced (e.g. SimResults.csv shows complied results).

I then updated the Energy Plus file to version 9,.0, ran it again in JE Plus with all else equal, and am not able to produce complied results (SimResults.csv file is empty). I note that the model does simulate with no issues as all of the individual output files are created in their folders.

Is there another setting specific to version 9.0 that I should be changing to get it to work with JEPlus? I am using version JEPlus v1.7.2.

Below is the .rvi file I am using, which is quite simple (I almost always this rvi file for most projects so am confident it works):

eplusout.mtr eplusout.csv Electricity:Facility Gas:Facility HeatingCoils:EnergyTransfer 0

here are my output meters:

Output:Meter,Electricity:Facility,Annual;

Output:Meter,Gas:Facility,Annual;

Output:Meter,HeatingCoils:EnergyTransfer,Annual;

Any help appreciated.

Hi Adam,

Thanks for raising this question! From E+ v8.9, the output frequency "Annual" and "RunPeriod" have been given different meanings. They were the same in the versions prior to that.

In jEPlus, the default output frequency is "RunPeriod" when RVI is used, hence it has troubles collecting "Annual" results from v8.9 and 9.0 models. You can either change to output frequency in the IDF to "RunPeriod", e.g.

Output:Meter,Electricity:Facility,RunPeriod;

Or to create a RVX file and specify "Annual" in the RVI object, such as:

my.rvx

{
    "rvis" : [ 
        { 
            "fileName" : "my.rvi",
            "tableName" : "Consumptions",
            "frequency" : "Annual",
            "usedInCalc" : true
        }
      ]
}
