Hi there,

I'm trying to run energy simulations through JEPlus v2.1.0 with the energyplus version 23.2. However I keep running into this error message when validating the project:

"Cannot find an E+ installation to handle model version 23.2 of the project! Warning: no report variable is defined. This project may not work with jEPlus+EA."

I was wondering if this has anything to do with the compatibility of the newest EP version to JEPlus. Is there a quick work around or is the only option to downgrade the IDF file to be compatible to JEPlus?

Thanks!

Hi,

Have you selected the location of E+ v23.2 in jEPlus? See the screenshot below.

Hi, yes I have. I am currently trying to downgrade the EP file to v8.9 and re-running it. Did v23.3 work for you?

Yep. If it still doesn't work, please share your system setup e.g. the OS and paths to E+ etc.

@Yi Zhang, This is same case for me, my idf file is 23.2 version and jeplus is not reporting the reporting variable. I tried it with a basic model still its not reporting it. Updating the files in a gdrive folder for your reference. Is it problem with energyplus version, If yes suggest a way to downgrade the e+ model. drive link : https://drive.google.com/drive/folder...

Not sure if I have answered this elsewhere... Your IDF model doesn't produce eplustbl.csv. Change "OutputControl:Table:Style, HTML;" to "OutputControl:Table:Style, commaandHTML;"
