Using knowledge from designing airflow systems for data centers, it is a matter of creating environments with definitive airflow paths. For air to travel from floor to ceiling, it requires floors with built in air outlets evenly distributed throughout the floor and air return evenly distributed throughout the ceiling in a distributed air pressure environment. In this case, air will travel from floor to ceiling directly. If air is to travel from ceiling to floor, having air outlets from ceiling, and air returns on the floor will solve the problem.
