Abstract

A material database has been developed for VOCs and formaldehyde emitted from building materials in this study. New classification system has been made by correlating the classification methods used in Korean Air Cleaning and Environmental Protection Agency. The developed databases include emission rates of TVOC, 5VOC and formaldehyde emitted from each building material. In addition, the databases can be used as an input variable to estimate indoor air quality (IAQ) using computer simulation since they also contain chemical component and general imformation. Box plot was used to do statistical analysis for emission rates of formaldehyde and TVOCs from different types of building materials. Also we confirmed the building materials worsening IAQ by categorizing the emission characteristic of different types of pollutants.

이 연구에서는 건축자재로부터 방출되는 휘발성유기화학물과 폼알데하이드의 오염물질 방출강도를 포함하는 데이터베이스를 개발하였다. 건축자재 분류체계는 환경부와 한국공기청정협회에서 사용하는 분류체계와 연계하여 세분류하여 정립하였다. 개발된 데이터베이스는 각 건축자재로부터 방출되는 총휘발성유기화합물과 5가지 휘발성유기화합물, 그리고 폼알데하이드의 방출강도를 포함하며 화학적 성분 및 일반적인 정보를 함께 포함하기 때문에 평가 모델링을 통한 실내공기질 예측에 입력변수로 사용 가능하다. 건축자재 분류별 폼알데하이드와 총휘발성유기화합물의 방출강도를 box plot을 이용해 통계적 분석을 하였다. 또한 각 분류별 오염물질의 방출특성을 확인함으로써, 실내공기질을 악화시키는 주된 원인이 되는 건축자재를 확인 할 수 있었다.
