Abstract

Self-management plan for GHG (Greenhouse Gas) reduction should be prepared in academic facilities, which occupy a large amount of energy consumption. In this study, a university was chosen as one of the major academic facilities and its energy consuming pattern and GHG emission were analyzed. The results have shown that annual $CO_2$ emission from university buildings was 10,452 ton-$CO_2$ (0.65 ton-$CO_2/m^2$), and dependent upon 78.0% electricity, 20.5% LNG and 1.5% oil, respectively as energy sources. According to more detail analysis by usage of energy consumption, appliances occupies 36.7% followed by gas heating (18.9%), lighting (18.6%), heating with electricity (12.5%), cooling with electricity (10.2%), transportation (1.5%), gas cooling (1.2%) and cooking (0.4%). Furthermore, annual $CO_2$ emissions per unit area and a student by electricity usage were evaluated to 51.30 kg-$CO_2/m^2$ and 981.86 kg-$CO_2$/capita, respectively and those by LNG usage were 14.61 kg-$CO_2/m^2$ and 241.01 kg-$CO_2$/capita.

대학은 그 자체로 거대 소비 주체일 뿐만 아니라 구성원 및 지역 주민의 생활 및 인식 전반에 큰 영향을 미친다. 이에, 본 연구에서는 대학교에서 발생하는 직접, 간접, 기타 온실가스 배출을 포함한 인벤토리를 구축하여 그 배출특성을 파악하고, 배출특성을 고려한 대학 내 온실가스 배출 저감방안을 수립하였다. 사례로 선정한 S대학교의 연간 $CO_2$ 배출량은 10,452 t-$CO_2$ (0.65 t-$CO_2/m^2$)이었고, 에너지원별로 전기 78.0%, 가스 20.5%, 석유류 1.5%에서 기인하고 있었다. 에너지의 사용목적에 따른 온실가스 배출량은 조명 18.6%, 동력 36.7%, 가스냉방 1.2%, 전기냉방 10.2%, 가스난방 18.9%, 전기난방 12.5%, 취사 급탕 0.4%, 수송 1.5%로 나타났다. 전기사용에 의한 단위면적당 및 학생 1인당 연간 $CO_2$ 배출량은 각각 51.30 kg-$CO_2/m^2$와 981.86 kg-$CO_2$/인으로 조사되었고, 가스사용에 의한 배출량은 14.61 kg-$CO_2/m^2$와 24.01 kg-$CO_2$/인으로 조사되었다.
