Effects of Flush-out on the Reduction of VOCs in Newly Built Residential Buildings

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 was conducted in three samples located in a suburban area of Seoul. From the results of the field measurements, it was found that indoor VOCs concentration decrease 63∼ 86% in the samples after flush-out. The number of day for flush-out has no significant influence on the reduction rate of VOCs, when the flush-out continued more than 7 days. Also, The comparison with bake-out showed that flush-out also can reduce VOCs as same levels of it in newly built residential buildings.
