Hello,

I have been trying to convert a very old IDF file from v6. I decided to follow 2 steps:


Step 1: v6 to v8.4Using the Multiple IDF Version Conversions https://energyplushelp.freshdesk.com/...

It seems that worked fine


Step 2: v8.4 to v9.0and from v9.0 Using this, copied the pre-processing libraries under the appropriate folder for EnergyPlusV23-2-0: https://energyplushelp.freshdesk.com/...


  • Conversion 8.4 => 8.5
  • Conversion 8.5 => 8.6
  • Conversion 8.6 => 8.7
  • Conversion 8.7 => 8.8
  • Conversion 8.8 => 8.9

It seems that worked fine


  • Conversion 8.9 => 9.0
  • Conversion 9.0 => 9.1
  • Conversion 9.1 => 9.2
  • Conversion 9.2 => 9.3

I get multiple warnings:

* Warning * IP: IDF line~66143 Obsolete object=AirTerminal:SingleDuct:Uncontrolled, encountered. Should be replaced with new object=AirTerminal:SingleDuct:ConstantVolume:NoReheat


  • Conversion 9.3 => 9.4
  • Conversion 9.4 => 9.5
  • Conversion 9.5 => 9.6

* Severe * IP: IDF line~66602 Did not find "AirTerminal:SingleDuct:Uncontrolled" in list of Objects

plus a number of warnings of the type:

* Warning * Object=Sizing:Zone, name=B1 N Meeting rms, entered with less than minimum number of fields. * ~~~ * Attempting fill to minimum. * Warning * Object=Sizing:Zone, name=B1 NE Meeting rms, entered with less than minimum number of fields. * ~~~ * Attempting fill to minimum. * Warning * Object=Sizing:Zone, name=B1 E DL Lobby, entered with less than minimum number of fields. * ~~~ * Attempting fill to minimum.


  • Conversion 9.6 => later versions

loads of errors


Nonetheless all IDF files get written / saved. I have tried opening the 22.3 IDF file within Honeybee for Grasshopper and I got the error message: The IDF is from EnergyPlus version 9.2. plus a number of other conversion errors

How do you recommend proceeding?

Are you using IDFVersionUpdater or the command line to manually update the files for each version?

Jason, I am using the IDFVersionUpdater

I'm confused by the file still showing it as EnergyPlus version 9.2. If you start with that file and just go up one version to 9.3 does it still show as 9.2?

JasonGlazer's avatar JasonGlazer  ( Jun 17 )

yes, strangely it does. All subsequent and intermediate versions saved in the conversion indicate "version 9.2"

Please send me your file or post it somewhere I can download it and I will try and see if there is a bug (I wrote IDFVersionUpdater). jglazer at gard dot com

An issue was identified when transitioning your file from 9.1 to 9.2 related to Table:TwoIndependentVariables to Table:Lookup. The issue is completely due to the EnergyPlus "transition" programs that are called from IDFVersionUpdater. I posted a GIthub issue about this here:

If you come across a similar failure shown when transitioning from 9.2 to 9.3 it may be caused by an incomplete transition from 9.1 to 9.2.
