I am modeling a building that has an underground garage. The garage is untreated (no heating or cooling) and mechanical ventilation is provided to each level of the garage from outside air. The garage is below part of my first floor level so the garage air temperature will impact my room loads and energy usage. Does anyone have any suggestions on how to model the garage area so the room temperature varies with outside air temperature?

Thank you,
Jeremy
