You are right that the OSM and IDF files are created under the hood for the comfort map recipes but they aren’t currently saved to the simulation folder. We only save the resulting .sql file since that’s all that is needed for the later simulation steps. @AbrahamYezioro actually asked to have the IDF stored in the result folder a while back and I was just going to add support for it this week. Are you ok if we only store the IDF and not both the IDF and OSM?
EnergyPlus can absolutely simulate unconditioned and passive buildings. Your models definitely don’t need to have HVAC systems in them and all that you have to do is set contioned_ to False when you create the room to have them be fully passive.
I’ll also say that people use the Adaptive model for mixed-mode conditioned/passive buildings all of the time. While the original studies for used to make the Adaptive model were done in fully passive buildings, a lot of experts now think it’s fine to use them in mixed mode buildings where people have the freedom to open windows and change their clothing.
