Readvars does not produce hourly CSV outputs

[eloneill]

When running a simulation and setting readvars=True, ReadVarsESO does not seem to process the eplusout.eso file into a CSV.

I am unfamiliar with eplusout.eso being converted into a csv file.
Can do you do this with EpLaunch ?
Can you point me to the documentation on this.

@ncbrown , are you familiar with this ?

I might have to experiment a bit to figure this our.

[eloneill]

When you run EPLaunch, this is done automatically. To be honest, I'm not even sure I see readvars=True doing anything in run_functions.py, but I'm far from an expert on the coding side of things. Could the problem be that that argument isn't running ReadVarsESO at all?

• idf.run() is a python wrapper around the EnergyPlus command line interface
• so in principle it should be able to do anything that the command line does. (and cannot do something that the command line cannot do)

In any case, I am a little curious now and will look into this.

I found two issues related to this

• ReadVarsESO not found through CLI NREL/EnergyPlus#5058
• EP-Launch Lite not running ReadVarsESO for standard .ESO file NREL/EnergyPlus#5898

I tested it with idf.run(readvars=True) with EnergyPlus-8-9-0 and ReadVarsESO is running on that version
From the above issues, it seems like the earlier versions (need to check which versions) are not running ReadVarsESO

I'll update the documentation to reflect this.

Ok I tested idf.run(readvars=True) with

• EnergyPlus-8-3-0 - DOES NOT make CSV
• EnergyPlus-8-4-0 - makes CSV
• EnergyPlus-8-5-0 - makes CSV
• EnergyPlus-8-6-0 - makes CSV
• EnergyPlus-8-7-0 - makes CSV
• EnergyPlus-8-8-0 - makes CSV
• EnergyPlus-8-9-0 - makes CSV

All testing was done on a Mac

I noticed in your unmethours question https://unmethours.com/question/30938/eppy-doesnt-produce-output-variables/ you are using E+ v 8.5

What platform are you on ?
Can you test with other versions of EnergyPlus on that platform

[santoshphilip]

I'll update the documentation in eppy to reflect this and then close this issue
