An investigation to understand the actual conditionsof smoking spaces was conducted, and itbecame clear that the introduction of a highlyefficientventilation system is necessary, in additionto the securing of a sufficient ventilationvolume. In addition, case studies using CFD andexperiments were conducted on the effects ofintroducing a highly-efficient ventilation systemto smoking rooms. As a result, a unidirectionalventilation system with a floor to ceiling airflow,such as a vertical tornado system, is highly effectivefor the improvement of the air environmentin smoking rooms, when compared to ordinarymixing ventilation systems.
