The Influence of Indoor Tobacco Smoking on Energy Demand for Ventilation.

The number of smokers differs mainly with age, sex, education, profession, and cultural background. The change in habits from the 2nd World War till today in form of increasing number of female smokers and decreasing number of male smokers is significant. The smoking of tobacco causes pollutants in the form of volatile organic compounds, particles, and carbon monoxide. Many of the pollutants are carcinogenic. In some cases the concentration of specific tobacco smoke related pollutants in room air may be higher than the maximum allowable concentration. In rooms where smoking is allowed the air change rate must be kept much higher than in rooms with only normal human odour load. The extra energy demand for ventilation in a room where smoking is allowed can be deduced from the necessary flow rate when smoking not is allowed. In this paper is discussed the ventilation energy impact of smoking. The estimation is made for the AlVC countries.
