DESCRIBES A FIELD STUDY WHERE FOR EACH OCCUPANT IN 15 RANDOMLY SELECTED OFFICE BUILDINGS THERE WERE ON AVERAGE 6 TO 7 HIDDEN OLFS: 1 TO 2 IN THE MATERIALS IN THE SPACE, 3 IN THE VENTILATION SYSTEM AND 2 CAUSED BY TOBACCO SMOKE. THE VENTILATION RATE WAS AROUND 25 L/S PER OCCUPANT, BUT ONLY 4 L/S PER OLF, WHICH EXPLAINS WHY 34% JUDGED THE INDOOR AIRTO BE UNACCEPTABLE.
