Hi Marko,
You can use jEPlus to run an IDF with multiple weather files, by either selecting all the weather files you want to include on the GUI, or putting the list in a text file (like the one below) and including it in the project.
C:/EnergyPlusV8-2-0/WeatherData/USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw
C:/EnergyPlusV8-2-0/WeatherData/USA_CO_Golden-NREL.724666_TMY3.epw
C:/EnergyPlusV8-2-0/WeatherData/USA_FL_Tampa.Intl.AP.722110_TMY3.epw
C:/EnergyPlusV8-2-0/WeatherData/USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw
C:/EnergyPlusV8-2-0/WeatherData/USA_VA_Sterling-Washington.Dulles.Intl.AP.724030_TMY3.epw
The benefit of using jEPlus is that it will create index for each case and extract results after simulation. To create those .def files, I used the following Python script before:
import os
import shutil
for file in os.listdir("D:\\ DSY\\ WeatherData\\London"):
if file.endswith(".csv"):
fn = os.path.splitext(file)[0]
print("procedssing " + fn)
# shutil.copyfile("D:\\ DSY\\ WeatherData \\HEB1976.def", " D:\\ DSY\\ WeatherData\\London\\" + fn + ".def")
f1 = open("D:\\ DSY\\ WeatherData\\HEB1976.def", "r")
f2 = open("D:\\ DSY\\ WeatherData\\London\\" + fn + ".def", "w")
for line in f1:
f2.write(line.replace("data record 1976", fn))
f1.close()
f2.close()
It basically just copy from a template and write it to a new .def with the same name as the .csv. Also it changes the comment line in the .def, so that the resultant .epw will contain the correct information. This is probably not the smartest Python code you can find; but it does the job.
Cheers,
Yi

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?
Marko
