Hi,

I know the community has answered some similar questions related to this but I could not find a viable solution as of now - pertaining to this.

When I export the OS Model as IDF, and open it using the IDF Editor, it shows the following prompt at first (see the image). After I click "Ok", this is followed by same pop-up (several times) - for different Spaces, after which the IDF Editor closes. Therefore, not allowing me to edit the IDF.

However, when I run the same model in OS Application, it (EnergyPlus Simulation) runs without any issue till completion.

Can anyone please guide me to sort this out - so that I can happily edit the IDF?

Hi Denis,

Hope you are well. Thank you for a prompt response.

As required:

1. One of the invalid SpaceList objects (from run/in.idf):

2. Same object from the IDF I exported:

Could you post one of these invalid SpaceList objects (from both the run/in.idf file, as well as the IDF you're exporting)? These are pretty simple objects, so it should be straightforward to spot the error (the reported message suggests a missing semi-colon at the end). Could you also post which versions of OpenStudio (or OpenStudioApplication) vs IDF Editor you're using?

Hi Denis,

I have provided the required information in/under "Edit-1" of my original post/question.

Thanks once again.

MHW ( 2024-08-19 08:45:09 -0600 )edit

It is possible that just before the SpaceList object is an object that doesn't end with a semi-colon. It might be easiest to diagnose the problem if you share your entire file.

Actually since you have 57 spaces listed and the native energy+.idd file only has 50 spaces, I think this is a case that you need to manually extend the energy+.idd file. See this question.

@JasonGlazer raises great points. I'm curious however how OpenStudio manages to launch EnergyPlus with the same inputs. @MHW, do you see any related issues reported in the run/eplusout.err file, when it runs successfully?

As could be drawn from the above discussion, the solution to this issue is not related to EnergyPlus. It is related to IDF Editor.

@JasonGlazer and @Denis Bourgeois raise some good points for the same and this answer stems from their guidance.

The solution to the above problem is as follows:

Open the IDD file of EnergyPlus in Notepad or any suitable editor.
Find the "Spacelist" object. This shall have these (click the link) parameters, as provided by @Denis Bourgeois in above comment. It will look like this in Notepad:

A1 , \field Name \note Name of the SpaceList. \note This name must be unique across Zone, Space, ZoneList, and SpaceList names. \required-field \type alpha \reference SpaceListNames \reference SpaceAndSpaceListNames \reference ZoneAndZoneListAndSpaceAndSpaceListNames A2 , \field Space 1 Name \begin-extensible \required-field \type object-list \object-list SpaceNames ... and so on till A50; \field Space 49 Name \type object-list \object-list SpaceNames

Open the IDF file in Notepad or any suitable editor.
Find the "Spacelist" object. Investigate the maximum number of "Space Names" in IDF. In my case this was "87" as indicated by the following (copying a portion of a Spacelist object from my IDF):

... T5_Residential_L14, !- Space Name 80 T5_Residential_L18, !- Space Name 81 T5_Residential_L8, !- Space Name 82 T5_Residential_L32, !- Space Name 83 T5_Residential_L4, !- Space Name 84 T5_Residential_L29, !- Space Name 85 T5_Residential_L5, !- Space Name 86 T5_Residential_L20; !- Space Name 87

Go back to IDD file in Notepad.
Remove the semicolon (;) after "A50" and replace it with comma (,)
After:

A50, \field Space 49 Name \type object-list \object-list SpaceNames

... add the following:

A51, \field Space 50 Name \type object-list \object-list SpaceNames

Keep repeating this (adding/incrementing fields) till you have:

A88; \field Space 87 Name \type object-list \object-list SpaceNames

Save and close the IDD file.
Open IDF in IDF Editor, it shall work fine.
