Does Ideal Air Loads affect temperature results?

In one of the models that I'm working on, I want to calculate the Zone Mean Air Temperature of a building with no HVAC, fans, or any other mechanical thermal conditioning. I'm currently running the models with Ideal Air Loads. Will the Ideal Air Loads modify in any way the Zone Mean Air Temperature, or Surface Face Temperatures?

Yes, Ideal Air Loads will try to meet your thermostat setpoints. If you want to look at behavior of your building without the conditioning then you need to turn ideal air loads off.
