The purpose of this study is to suggest improvement plans of School Green Building Certification System by comparing items of domestic system with those of foreign system. Especially, we focused on school use classification. Use classification of Green Building Certification System must be based on Building Codes and reflect the nature of building use and size. Schools are divided into three groups ; preschool, school(elementary, junior high school, high school), university and ect. Also they must be set up assessment method reflecting the nature of school use and size.

The purpose of this study is to suggest the way how to improve the school green building certification system based on life cycle assessment methodology and to assess $LCCO_2$ in outline. Green Building Certification System for School is comprised of 7 categories and 39 items. 7 categories include Land use and Transport, Energy and Atmosphere, Materials and Resources, Water, Management, Ecology, Indoor environmental quality. School is a public facility for students. So Green Building Certification System for School must have educational point of view adding to energy saving, reduction of greenhouse gas emission, etc. Also it needs to be classified into three categories ; kindergarten, elementar/middl/high school and university. Improvement plans for items are as follows ; energy consumption and $LCCO_2$ assessment considering life cycle, deletion or integration of duplicate items by comparing other systems, application of passive solar systems, consideration of the law and standards change, and selection of items considering specific building use.
저온 플라즈마 및 암모니아 선택적 환원공정을 활용한 저온 탈질공정의 특성(II)

연소 배기가스 중의 수분, 탄화수소 및 CO가 저온 플라즈마 및 $NH_{3}$ SCR (Selective Catalytic Reduction)공정이 복합된 탈질공정에 미치는 영향에 대한 연구가 수행되었다. 실험결과 일반적인 SCR 반응에 비해 매우 빠른 반응속도를 갖는 fast SCR 반응은 $150{\sim}200^{\circ}C$의 저온조건에서 탈질율의 상승을 가져다주지만, 처리가스 중에 탄화수소가 있는 경우 fast SCR 반응의 역할이 상당히 감소되는 것을 확인할 수 있었다. 이는 저온 플라즈마 반응기에서 부분산화반응을 통해 탄화수소 중 일부가 알데히드로 전환되며, 알데히드는 fast SCR 반응에 있어 중요한 변수인 $NO_{2}/NO_{x}$ 비율에 영향을 주기 때문인 것으로 설명되었다. 한편, 수분 및 CO가 fast SCR 반응에 미치는 영향은 탄화수소에 비해 상대적으로 적음을 확인할 수 있었다. Effects of water vapor, hydrocarbons, and CO, which are inevitably included in exhaust gases of combustion, on a combined $De-NO_{x}$ process of non-thermal plasma and $NH_{3}$ SCR (Selective Catalytic Reduction) have been investigated. Test results showed that fast SCR reaction enhanced $De-NO_{x}$ rate under the low temperature conditions, $150{\sim}200^{\circ}C$ The present test, however, showed that the role of the fast SCR reaction can be significantly suppressed by addition of hydrocarbons in a non-thermal plasma reactor. Detailed investigation verified that such suppressed role of the fast SCR reaction could be caused by the $NO_{2}/NO_{x}$ ratio modified by aldehydes produced from hydrocarbons in a non-thermal plasma reactor. In addition, the present study was confirmed that the effects of water vapor and CO were not noticeable compared with the hydrocarbon effects.
