The EnergyPlus Climate Data Summary depends on the .stat file that has the same name and in the same folder as the .epw file. So to fix the problem, you might need to locate the .stat file and make sure it is in the same folder as the .epw file.

Hey Jason, I am sure the .stat file is in the same folder, yet it populates SizingPeriod:DesignDay, Monthly Precipitation Summary, and an empty Weather statistics file table. Is there a preferred location for the weather files?

I don't think it should matter where the files are. Sorry, I can't think of any other solution to your problem. Does this happen with other weather files in other locations?

Sadly, yes, all weather files so far, same table, empty. By the way Jason, I only need this table because I am trying to run the PRM 90.1 2019 appendix G measure, after the measure is run successfully and I try to run the checker, I get this error "line 392, in add_weather climate_zone = rows['ASHRAE Climate Zone'][0] KeyError: 'ASHRAE Climate Zone'"

Does the stat file contain the ASHRAE Climate Zone. If it does there should be a line in the stat file that looks like:

  • Climate type "3C" (ASHRAE Standard 196-2006 Climate Zone)**

You can open the stat file with any text editor, such as Notepad.

Yep, "Climate type "4A" (ASHRAE Standard 196-2006 Climate Zone)** - Mixed - Humid, Probable Köppen classification=Cfa/Dfa, Humid Subtropical/Humid Continental (Warm Summer)" line 528. The problem I think is that it is not linked inside the OpenStudio and it does not make it to the epjson to be read by the PRM checker
