Optimal Layout Design according to Potential Assessment of Rooftop Photovoltaic System on Southeast-facing Buildings for Establishing Green Campus

Abstract

This paper presents an optimal layout design of rooftop photovoltaic (PV) system that maximize the power output for each building in Kangwon National University's Samcheok Campus. The available area was calculated by excluding fixed facilities and shaded areas on the roof of each building. The inclination of module was set to onsite latitude value. Considering the characteristics of rooftops, two layout designs of the solar module were applied (southeast facing-parallel to the rooftop boundary that maximizes the number of modules and south facing that maximizes PV power generation efficiency) to 14 buildings to analyze and compare the PV potentials. As a result using the RETScreen software generally used, the southeast-facing installation method showed higher potential for 11 buildings, while the south-facing installation method was selected as the optimal design for three buildings. This result can be used as basic data for designing the rooftop PV system. 서 론 파리기후변화협정이 2015년부터 본격적으로 발효되면 서 에너지 전환과 그린 뉴딜 정책의 중심에 신재생에너지 가 핵심요소로 꼽히며 사회 전반에서 다양한 방법으로 온실 가스 감축을 위한 노력이 진행되고 있다(Suh and Brownson, 2016; Suh et al., 2020). 특히, 대학은 거대한 에너지 소비 주체로써 교육뿐만 아니라 온실가스 감축을 통해 사회와 환경에 기여할 필요가 있다. 온실가스 감축 방안으로 다양 한 방법들이 검토되고 있는 가운데 대학 캠퍼스 공간을 직접 연구논문
