Hi folks! Has anyone ever made any output converters for EnergyPlus they'd be willing to share? Specifically I'm interested in converters that allow outputs from more recent versions of E+ to be shown in the output format of older versions. Output variable names have been changed and reported in different ways. Interested in being able to convert to 8.5 format if possible. OK if it's an OS measure. Feels like a long shot but thanks for any help or insight! Andrew

Or thinking about it some more - does anyone have an OS measure that generates old E+ output files from OS?

@Andrew_Corney, I'm asking around a bit. OS reporting measures primarily reads the E+ SQL file (so its more of an E+ reporting measure), but it does also have access to IDF and OSM file as input files that can be used for report, if for example you want to see data by space type or building story, or include combination of input and output data in a report. They typically write out to HTML, CSV or some other format. The only example writing back to SQL is Radiance reporting that added illuminance maps to the E+ SQL file. What you are describing might be possible but I have not seen it.

I'm not aware of any tool that does that automatically. But the definitive list of changes made to output is in here:

And the Report variables changes are in

My (perhaps naive) feeling about it is that I don't think it'd be a daunting task to write such a tool. As you'll see, most of the Report Variables CSVs are empty of changes, and when it's not, load it as a dict and replace variable names to the old name, do that for each version from current back down to 8.5.

Thanks Julien, That's really helpful. Hopefully not a daunting task, no - this list makes it seem more manageable :-) cheers, Andrew
