Currenty, I modeling hotel contain bedroom with AC and bathroom without AC. Those rooms separated by glass door. Based on guest habit, the door maintains open so the conditioned air from the bedroom comes to the bathroom. There are two exhaust fan placed in the bathroom. How to combine the thermal zone between bedroom and bathroom? should I make it two zone? how to define airflow comes to the bathroom? I'm trying to use air network but I don't know the pressure difference between them. Or can I just make one zone contain bedroom and bathroom conditioned with AC and exhaust fan? What the consequences? Your answer will really helpful. Thanks.

My guess would be to model one thermal zone, as the opened glass door would create a direct connection between the bedroom and bathroom. The main question would be about the exhaust fan: Is it always on or active only when the bathroom is being used? If that's the case, maybe you could model it with an irregular schedule to mimic it's use, but would it be worth?

Thank you Bruno! For exhaust fan scheduling according to the lighting schedule, because usually guest will turn on the light when using the bathroom, the problem is standard scheduling from ASHRAE or DoE doesn't have a specific schedule for it.
