| Abstract |
Recently, IAQ(Indoor Air Quality) is regarded as one of the most important environment factors as well as thermal and acoustic comfort. A lot of paints, adhesives and chemical materials which are known to emit gaseous chemical pollutants are being used in building. These building materials are potential sources of indoor chemical substances. Bake-out has been as one of mitigation methods for the chemical substance contained in the building material. However, an examination about the effect of the bake-out is not sufficient. So, this study was conducted 1) to establish the bake-out procedure and evaluation method used with new apartment in winter, 2) to determine the effectiveness of the bake-out on formaldehyde and VOCs reduction. From our results, in winter, it was confirmed that the emission rates of formaldehyde and VOCs decreased after bake-out in a temperature of 32∼33℃ for the period of 72hours, and next to put in operation 1days(about 8hours) of cross ventilation. |
