Abstract
Green Infrastructure (GI) approach provides significant benefits to cities and communities. GI applications would provide multi-benefitssuch as the reduction in building energy demand, stormwater management, urban heat island reduction, habitat creation, etc. GI isnowadays considered as a multi-benefit best management practice (BMP) at diverse levels of government. The purpose of this study isto find out the positive effects of GI application, and Geographic Information System (GIS) is used for the accurate and efficient analysis.Two polygon data, ‘GreenRoof’ and ‘ParkingPlace’ are produced with a satellite imagery extracted from Google Earth Pro. These dataare used to calculate total available spaces for green roof and permeable pavement in the campus of Chungbuk National University. AfterGI application in the campus, 13.2% of landcover is converted to green spaces and this change results in expanding the green networkof Cheongju city. The result of this study shows that green roof application can absorb 4576.95 kg/yr of Carbon Dioxide and possiblyreduce maximum 1,497,600L urban runoff. This study proves how GI is valuable for the city environment with quantitative analyses.
