Smoking and Ventilation
ASHRAE standard 62 states that air removed from an area with environmental tobacco smoke shall not be recirculated into ETS-free air. A space with ETS requires more ventilation to achieve similar perceived air quality to that of a non-smoking environment.
The amount of ventilation in an ETS area is equal to the amount of ETS-free area plus the amount V, where:
V = DSD × VA × A/60E
- V = recommended extra flow rate in CFM (L/s)
- DSD = design smoking density (estimated number of cigarettes smoked per hour per unit area)
- VA = volume of ventilation air per cigarette for the room being designed (ft3/cig]
- E = contaminant removal effectiveness

Famous quotes containing the words smoking and and/or smoking:
“I was always able to understand my friend who decided to quit smoking and who, through an effort of will, succeeded in doing so. One morning, he opened the newspaper, read that the first H- bomb had exploded, found out about the bomb’s admirable effects and went straight to the tobacconist’s.”
—Albert Camus (1913–1960)
“As an example to others, and not that I care for moderation myself, it has always been my rule never to smoke when asleep, and never to refrain from smoking when awake.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
