An office building with constant-volume system has a filter located
before the outdoor air intake vent with efficiency of 75% for
environmental tobacco smoke (ets). there are 10 occupants, 2 of
whom are smokers. data indicates that smoking one cigarette per
hour produces between 5 and 10 µg/s of particulate matter pm10.
taking the average, a production rate of particulate matter pm10
at 2×7.5 = 15 µg/s can be assumed. the outdoor airflow rate is 20
cfm per person, the supply airflow rate 50 cfm per person, and the
return airflow rate 40 cfm per person. the ventilation
effectiveness is 0.9. assume that there is no ets outdoors.
evaluate the iaq based on air quality standards set by u. s. epa?
