The Effect of Ventilation on VOCs Emission rate during the Bake-out Procedure in Newly Constructed Apartments

신축 공동주택에서 베이크 아웃 시 환기 조건에 따른 마감재에서의 방출량 저감 효과

Various kinds of contaminant are generated from many kinds of interior construction materials, furniture and life articles. People of today living indoor most of the time are exposed to these kinds of contaminant. In this connection, people are exerting their efforts to reduce the occurrence of contaminant from the interior finish materials. And it is the actual condition that research is being actively made on the method of reducing contaminant by performing bake-out for newly constructed housings. Bake-out is the method of temporarily increasing the generation of the harmful contaminant quantity including VOCs and Formaldehyde emitting from construction materials or finish materials by increasing the interior temperature of the newly constructed buildings or improved or repaired buildings, and then removing it by mobilizing ventilation system. In this study, the researcher measured the effect of reduced concentration according to ventilation or non-ventilation of the newly constructed but not yet resident public housings during the bake-out in order to grasp the effect of reduced interior air contaminant according to the elapse of timeat the time of bake-out.
