This is very easy if you do your runs using the runeplus.bat batch script.
Just write a master batch script that calls runeplus repetitively with the same input file name (idf) but changing the weather file, i.e.:
call runeplus [idf file name w/o the extension] [weather file name w/o the epw extension]
call runeplus [idf file name w/o the extension] [weather file name w/o the epw extension]
For example, if your idf file is called marko.idf, and the weather files are called nis1.epw, nis2.epw, nis3.epw, etc. then the master batch file would be
call runeplus marko nis1
call runeplus marko nis2
call runeplus marko nis3
The one thing to remember in your case is to change runeplus.bat to copy the output files to [idf filename + epw filename] instead of just [idf filename] or else you'll just get one set of output files since the idf filename is the same.
Then, after the master batch file has been run, you will get the output files as:
markonis1.eso, markonis1.rdd, etc.
markonis2.eso, markonis2.rdd, etc.
I know the runeplus.bat that comes with EnergyPlus has some "bells and whistles" that can be confusing and mask what's being done, which is actually quite simple - it copies the input idf and weather file to in.idf and in.epw, runs EnergyPlus, and then copies the output files (eplusout.*) to input file name.*(same output extension).
Attached are an old runeplus.bat and runalleplus.bat set up to do 200+ EP runs at one shot. Your main problem will be in getting the locations (paths) of your input file and weather files correct, and then changing the output filename from "%output_path%%~1... to "%output_path%%~1_%%~2... or something like that.

Hi all,
i am trying out to create hundreds of weather files where only temperatures for 1 (max 2) day will be perturbed. I know that every csv weather file requires a def file (all of them will have the same structure, only the names will defer) and this can be done from outsource, but my concern is how to run simulations for the same idf file with various weather files. Is there some kind of parametric processor like jEplus or similar that can do the job?
