Hi @sshimizu ,
I just pushed an updated set of comfort-mapping recipes to the development version of the plugin. There are a lot of improvements in the new version and one of them is that the IDF now gets copied to the simulation folder such that you can check the EnergyPlus input. So, if you update to the development version with the LB Versioner, you will now see that the IDF gets stored in:
The way EnergyPlus simulates passive buildings is not really muchdifferent than how it simulates conditioned ones. It just doesn’t supply heating and cooling to meet the zone setpoint so the temperature of the room increases or decreases accordingly. So I don’t know of anything specific I could point you towards except to try running a simulation of an unconditioned room yourself and see that the indoor temperatures are far from typical setpoint values.
