새건물증후군이란 새로 지은 건물에서 생활하는 사람들에게 눈이 따갑거나 목이나 코가 아프거나, 두통, 구토, 피부발진 등 증상이 나타나는 것을 일컫는 말이다. 새집증후군 원인물질의 주요 성분으로는 건축 자재나 벽지, 페인트, 가구 접착제 등에서 발생되는 포름알데이드(HCHO)와 톨루엔 등 휘발성 유기화합물(VOCs: Volatile Oragnic Compounds), 부유 박테리아, 곰팡이, 바이러스 등이다. 새집증후군을 저감하기 위한 방법으로는 환기에 의한 방법, 오염물질이 없는 친환경 재료의 사용 및 재료의 처리를 통해 오염물질을 저감하고자 제거하는 방법이 있다. 본 연구는 이들 방법 중 건축 재료 위에 표면코팅처리를 함으로써 실내 공기질을 향상시키기 위한 것으로, 건물 내 표면 코팅 전후의 공기질을 분석함으로써 실내 거주환경을 안전하게 조성하는 데 그 목적이 있다.

Sick Building Syndrome (SBS) is an illness symptom such as irritation of eyes, skin eruption and vomit ing in newly constructed buildings. It is mainly due to the harmful gases from the materials installed in building such as Volatile Organic Compounds (VOCs), Semivolatile Organic Compounds (SVOCs), floating bacteria, fungi, fungal spores and viruses, human bioeffluents in many modem buildings. The general ways to improve the Indoor Air Quality (IAQ) are ventilating, utilizing eco-material without harmful gases and reducing or removing harmful gases through additional treatment to the building materials. This study aimed to improve the Indoor Air Quality(IAQ) by applying surface coating on the building materials and to make safe living environments through the analysis of air quality before and after surface coating treatment in buildings.

제안 방법
1) Manufactured LT-1 photocatalyst's physical and chemical properties were examined by nitrogen absorption, XRD, and the TEM technique. This contains higher anatase than the photocatalyst P-25, and particles are uniform and four times big흥er.
In this study, in order to seek alternatives to remove substances causing sick building syndrome, raw materials are manufactured by water heating composition. The results from this study are as follows:
The final solvent is manufactured by reacting as water heating composition over six hours. The crystal structure, particle size, and surface area of manufactured photocatalysts are examined through XRD (Rigaku D/MAX-1200) pattern, TEM (JEOL, EIM-2000FXII: Korea Basic Science Institude/Gwangju Branch) photo, and nitrogen absorption experiment, which are powder obtained after drying photo catalytic sol at one hundred degrees. In the present experiment, the character of manufactured photocatalysts is compared with a common photo catalytic powder, P-25 (Dequssa, Germany).
The formaldehyde and TVOC is measured by using Z-300P (Environmental Sensors Co.) and IAQRAE (RAE System, Inc.), and floating bacteria in the air is examined by measuring the number of bacteria culturing at 37 degrees after installing BHIV badge at Air Sampler (MAQ.S.Ⅱ, OXOID Co.) and inhaling air for a regular period of time. Measuring floating bacteria is averaged by two measurements at the same place.
This study examines its physical and chemical characteristics by manufacturing a photo catalyst including a high-efficiency corpuscle dioxide titan and checks its applicability as an indoor environment purification material by examining the effect of removing substances causing the sick bwlding syndrome after coating a photo catalyst in newly built apartments, classrooms, and offices.
성능/효과
2) Formaldehyde in materials coated with LT-1 was removed for two hours over 90%, and colon bacteria and corona viruses were checked to eliminate them over 99.9%.
3) Coating LT-1 photocatalysts to the inside of newly built buildings is checked to remove substances like formaldehyde, VOC, and floating bacteria in the air. As a result, the substances were decreased under the limit of criteria.
