Abstract

This study aims to provide basic materials for expanding application of green roof afforestation by analyzing structures' energy consumption reduction effects according to green roof afforestation as a planning means to cope with climate change. As the subjects, recently completed apartment buildings and service facilities of apartment houses where green roof afforestation was applied were selected. green roof afforestation of Extensive Green Roof(soil depth: 20cm) and Semi-Intensive Green Roof(soil depth: 40cm) in construction types was applied and design builders were utilized in order to compare energy reduction amount according to the application of green roof afforestation. According to the analysis result, all the buildings had energy reduction effect when green roof afforestation was applied.

본 연구는 기후변화 대응을 위한 계획적 수단으로서 옥상녹화에 따른 건축물 에너지 저감효과를 분석하여 옥상녹화 적용확대를 위한 기초자료를 제시하는데 목적이 있다. 대상지는 최근 준공된 공동주택 중 옥상녹화가 적용된 주동과 부대복리시설을 선정하였다. 건축 유형에 따라 경량형(토심 20cm) 및 혼합형(토심 40cm) 옥상녹화를 적용하고, 디자인 빌더(Design Builder)를 활용하여 옥상녹화 적용에 따른 에너지 저감량을 비교 분석하였다. 분석결과, 모든 대상 건축물에서 옥상녹화 적용시 에너지 저감효과가 있으며, 혼합형 옥상녹화가 경량형 옥상녹화에 비해 냉 난방 에너지 저감효과가 더 큰 것으로 나타났다.
