Abstract The purpose of this study was to confirm the effects of flush-out on the reduction of Volatile Organic Compounds(VOCs) concentration in newly built residential buildings. The field measurements were conducted in two complexes of multi-residential buildings which are located suburban areas of Seoul. About three samples of residential buildings were selected in the field measurements. Two samples, B and C, had been flush-out with outdoor air more than seven days. The sample A was maintained at same condition during the flush-out because of the comparison. The indoor concentrations of VOCs in the three samples were measured at three times, before, during ,and after flush-out. From the field measurements, it was confirmed that two samples' indoor VOCs' concentrations were considerably decreased after the flush-out comapred with those of the sample A in which the flush-out was not conducted. The decreases of indoor VOCs concentrations were corresponding to about 50% ~ 92% of the concentrations of before. Through the reviews for the previous studies, it was also found that the reduction effects of the flush-out is similar with the those of the bake-out which were reported in the previous studies.
