It seems troubleshooting what ARCHICAD does with the energy model is like poking around in the dark.
This article might help you to start, though:

This is the PDF guide for Ecodesigner Star (with features you won't have access to):

Also, taking a look at the Ladybug Discourse has some interesting discussions, if you type "ARCHICAD" in the search bar. Mostly about issues, unfortunately.
The Unmet Hours community doesn't have much discussions related to it.
Do you need the results for code compliance? Well... how valid are the results? According to the HelpCenter article the simulation kernel and Strusoft's stand-alone VIP Energy product is validated according to ANSI/ASHRAE Standard 140-2007. They also note that
Code: Select all
"To produce code-compliant energy simulation results, the expert user interface of EcoDesigner STAR is necessary."
Info from here: https://help.graphisoft.com/AC/24/int/_ ... ion-28.htm
Interestingly, they don't say ARCHICAD's Energy Evaluation or Ecodesigner STAR is validated against any measure, just the engine that they use.
Too bad the "more info about the engine" URL is not working. After a few minutes of googling there isn't much available material in English for the VIP engine either:
https://strusoft.com/uploads/documents/ ... IP_ENG.pdf
The overview is in Swedish, I don't understand it unfortunately: https://strusoft.com/products/vip-energy#documents
Maybe someone from Sweden or from GRAPHISOFT could give an overview.
I find it odd, that there is zero trace of a conductive side by side comparison available, against Energy+ for instance (so you have a well documented base to compare to).
