Abstract

In this study, the surface temperature of the roof green system using ALSRBA(Artificial Lightweight Soil Recycled with Bottom Ash) was measured in each season and the thermal property of the ALSRBA was investigated. As a result, it was certified that ALSBRA has superior thermal property than the usual artificial soil. In addition, The daily temperature range in each season was measured to investigate the thermal isolation property of EUS(Existing Unit System) and DUS(Developed Unit System). The result showed that the thermal isolation effect of EUS was lower than that of SPSS(Site-Place-Soil System), but thermal isolation effect of DUS was similar to that of SPSS because DUS has continuous ALSBRA layer by removing unit barrier.

본 연구에서는 바텀애시 재활용 인공토양을 적용한 옥상녹화 유니트 시스템의 표면 온도변화를 계절별로 측정하여 바텀애시 재활용 인공토양의 열특성을 분석한 결과, 바텀애시 인공경량토양이 기존 토양보다 우수한 열차단 특성이 있음을 확인하였다. 또한, 기존 옥상녹화 유니트 시스템과 개발 옥상녹화 유니트 시스템의 열차단 효과를 분석하기 위해 계절별 일교차를 측정한 결과 기존 녹화 유니트 시스템은 현장 포설형 녹화시스템보다 열차단 효과가 낮은 반면 격막을 탈거하여 바텀애시 인공경량토양을 연속된 층으로 형성하는 개발 유니트 녹화 시스템은 기존 현장 포설형 녹화시스템과 유사한 열차단 효과를 갖는 것으로 분석되었다.
