I have csv data file which has data from 3/3/2016 to 3/3/2017. When I set this in Run Period as start month 3 and start day 3 and end month 3 and end date 3, energyplus is unable to perform on whole year simulation. The standard procedure is to use 1/1 as start month and date and 12/31 and end month and date. Can someone suggest a way to solve my issue?

You need to use RunPeriod:CustomRange and an EPW weather file that spans this period.

Thank you so much for the answer. It works. But now can you please suggest from where can I get the custom weather file? Since current weather file which I am using is from default EnergyPlus weather files. I do not have weather file corresponding to the dates I have mentioned here...

Given that appear to be trying to load real datapoints into your model, I assume you want to use ACTUAL weather data, as opposed to Typical Meteorologic Year (TMY, what the E+ weather website will give you). (Otherwise you could just process the EPW as a CSV and move the Janunary to March lines to the end and repackage as EPW)

Thanks Julien!!! this is very helpful.... I will try to do this but I have never attempted something like this before. Can you refer me to any documentation or if you don't mind can you spell some the procedure to achieve this so that I can complete this task? This will immensely help me.

Thanks again..

You need to use the weather converter, this ref guide. It's really not as complicated as it looks like. Load EPW in weather converter -> convert to CSV. Open CSV and move rows (and potentially duplicate one for march 3). Load new CSV in weather converter -> convert to EPW.

Thank you very much, Julien! It worked, I solved the issue and the simulations are working as I expected.... Thanks again for your help....
