리모델링 학교 및 신축학교 실내공기질 측정과 대책

Abstract

In order to evaluate the quality of indoor air due to the remodeling and newly-built in S City, 60 schools wereinvestigated in formaldehyde (HCHO) and total volatile organic compounds (TVOCs). One school exceeded thenational standard of formaldehyde 100 μg/m3 at 1st measurement. Thirty-eight schools showed higher level ofTVOCs over 400 μg/m3 at 1st measurement. Twelve schools showed higher level of TVOCs over 400 μg/m3 at2nd measurement. This result derived from TVOCs which originated from the building materials and finishingmaterials. To prevent the pollution of indoor air quality at schools caused by formaldehyde and TVOCs, therecommendation of environmentally-friendly building materials, the diminishment of emission by bakeout process,the efficient combination of natural ventilation and mechanical ventilation, and antibacterial effect of chemicalcontrol measures as photo-catalysts should be given positive investigation.
