Add "Output : Diagnostic" to idf

edit

The second answer in this post discusses the Output:Diagnostics object, which in its raw text form looks like this:

Output:Diagnostics,
  DisplayExtraWarnings;

You can add this raw text form of the object directly to the EnergyPlus input file (IDF) in any text editor. If you aren't comfortable with that and want to add this in IDF Editor, this post discusses the process of adding new objects. You can also copy the raw text form of the Output:Diagnostics object and paste it into IDF Editor. You should then see an item in the Class List on the left of IDF Editor for Output:Diagnostics.

Yes, you can integrate external EnergyPlus objects into DesignBuilder. You have two options to do that:

• If you paid for the Scripting module, you can add EnergyPlus objects in their raw text form to a script that's included in your DB file.
• If you didn't pay for the Scripting module, another option is to include an external file that has EnergyPlus objects in their raw text form. The relevant section for doing this is near the bottom of the help documentation I linked to.
