# .BuildSysPro.IBPSA.Airflow.Multizone.Examples.ReverseBuoyancy

Model with four rooms and buoyancy-driven air circulation that reverses direction

## Information

This model is similar than IBPSA.Airflow.Multizone.Validation.ThreeRoomsContam but it has four instead of three rooms. The outdoor conditions are held constant at 10°C and atmospheric pressure. All four rooms are at different temperatures, with the rooms on the bottom floor being initially at a higher temperature than the rooms on the top floor. As time progresses, the temperatures of the two rooms on the respective floors asymptotically approach each other. The bottom floor eventually cools below the temperature of the top floor, because the bottom floor directly exchanges air with the outside.
