Sick house syndrome (SHS) has been a social issue in Korea, and, after then, many people are interested in indoor air quality (IAQ). By the regulation on architectural equipment standards enacted on February 13, 2006, it became obligatory to install the ventilator, which has the ventilation rate above 0.7, in apartment houses for the improvement of sick house syndrome. The ventilation rates mentioned above was made by the consideration of VOCs concentration and formaldehyde concentration. However there are many pollutants in indoor space, and it is reasonable to decide ventilation under the investigations on those many kinds of pollutants. In this study, ventilation rate is recommended from the viewpoint of indoor concentration of carbon-dioxide. The recommended ventilation rate was investigated by field measurement and theoretical prediction formula. The ventilation rate, in this study, is recommended at 1.1h-1. and it does not contain infiltration rates but only by ventilator. Not only the concentration of air pollutant, but also the odor spreading in indoor space is a big issue in the field of indoor air quality. In this study, the air exchange rates between master's room and living room of dwelling unit of apartment house were investigated. Theoretical consideration on the data analysis for air exchange rates between rooms was conducted and the calculation of air exchange rates between rooms was tried. The air exchange rates between living room and master's room was calculated at 4.14CMH. For the further study on air exchange rates between rooms, it needs to study on the generalization under the conditions of temperature differency between rooms.

새집증후군에 의한 실내공기 오염문제가 사회적 이슈가 되면서 실내공기질에 대한 세간의 관심이 크게 증가되었다. 이로 인해 정부에서는 새집증후군의 해결을 위하여 2006년 2월 13일에 ‘건축물의 설비 기준 등에 관한 규칙을 개정하여 환기 횟수 0.7회/h 이상의 자연환기설비 또는 기계환기설비의 설치를 의무화하였다. 주택의 경우 새집증후군의 원인물질인 VOC, 폼알데하이드(HCHO)외에도 다양한 오염물질이 존재한다. 따라서 실내의 적정 환기량은 새집증후군 물질만이 아니라 다양한 실내공기 오염물질을 대상으로 분석하여 종합적인 판단을 할 필요가 있다. 특히 이산화탄소는 실내공기 오염의 척도로 사용되는 대표 오염물질이다. 이동주 등은 CO2를 오염원으로 하여 실험한 결과 환기횟수 0.6회/h (30CMH)로는 환기를 효과적으로 하기에 부적절하며, 3인이 재실하는 경우의 효과적인 환기를 위한 환기량으로 1.2회/h (60CMH)를 제안하였다.
