| Abstract |
The purpose of this study was to analyze the reduction of temperature according to planting method and coverage ratio of plant for the sloped green roof. The temperature reduction effects were investigated using plants, that usually installed for green roof system, such as Carex komobugi, Sedum mix(Sedum middendorffianum : Sedum sarmentosum : Sedum acre : Sedum album = 1 : 1 : 1 : 1) and so on. The coverage ratio of Sedum mix. for roof greening was at almost 80%, that was higher than that of Carex komobugi, at 50%. But in flat condition(slope 0°), Carex komobugi showed significantly higher coverage ratio than Sedum mix. In the case of module type, the coverage ratio of Sedum mix is the highest at 87% on 20° slope, while that of Carex komobugi is at 73% on 0° slope in installation type. |
