Hey, for example I have the following models in EnergyPlus:

  1. A “basic model”
  2. A model with HVAC 1
  3. A model with HVAC 2

Now I want to change something in the “basic model” (for example a geometry) - but I don’t want to change this in all 3 models. Is there a possibility to build such a “base-model” where all changes will be applied automatically in the “test models”?

If you are familiar with Python, on way you could do that would be to write a script using Eppy and then call it for each model.

I second the use of Eppy, which is in Python.

I would also recommend OpenStudio, if you want to start using that ecosystem. This kind of workflow is precisely what Measures (which are in Ruby) helps accomplish. You would basically have a Measure for 2. and 3. where the Measure changes the baseline model to have HVAC 1 or HVAC 2. Thus if you change the baseline model, the measure should work exactly the same (if written well).

I think without some form of scripting, this is an exercise in patience and attention to details. I would highly recommend looking into a scripting option.
