Hello,

I am trying to run an energy simulation using OpenStudip-HPXML, but I get a fatal error. On checking the eplusout.err log file, it says the following:

Program Version,EnergyPlus, Version 22.1.0-ed759b17ee, YMD=2023.02.13 21:27,

Seems like a similar error as reported here. In that case, the issue was that "we’re writing the year as a float value (2001.0) instead of an integer value (2001)". So it looks like you need the line to start with "2022" instead of "2022.0".

Thanks for the reply! I checked the EPW file by loading it in excel, and the year column holds integers, not floats, so this should not be the issue.

Excel sometimes applies formatting to what it displays. You need to look at the file in a text editor.

You were right! Notepad++ was able to capture the issue; thank you so much! Any tips on how to solve this optimally? I tried to convert the year column into number in excel and made sure there were no decimal points. But I get the following error:

[17:40:01.340453 ERROR] D:\OSN\src\utilities\filetypes\EpwFile.cpp@2553 : EpwFile 'C:/Users/kkhar/Downloads/OpenStudio-HPXML-euss.2022.1 (1)/OpenStudio-HPXML-euss.2022.1/workflow/Phoenix_Arizona/upgrade0/bldg0000578-up00/Phoenix_MPI_2020_2039_edited.epw' cannot be processed

@krkh-1702 it might be safer to open the EPW in Notepad++, search for "2022.0", and replace ALL with "2022". If Notepad++ doesn't have a 'replace all' feature, then you can use Visual Studio Code as an alternative text editor. As @shorowit mentioned, Excel applies formatting in strange ways, so converting the year column into a number perhaps affected the way EnergyPlus reads the EPW.

Great, I will try this out!

It's trying to tell you this is a line in error. Should be year,month,day
