ABSTRACT

The purpose of this study is to develop urban planning for mitigating thermal comfortby analyzing the relationship between various physical environmental factors and radiation fluxesfocused on urban areas of Changwon city, Gyeongsangnam-do. Physical environmental factorswere analyzed by sky view factor (SVF), land cover and land use types using GIS program. Radiationfluxes were measured upward and downward in solar and terrestrial radiation by mobilemeasurement during 3 days (2 daytime and 1 nighttime) in summer season. SVF is high in urbanpark less around buildings. High dense building sites were low. Downward solar radiation fluxeswere the highest about 700W/m2 at daytime, and decreased in spatial type arranged densebuildings. Upward solar and terrestrial radiations was affected by land cover types that have thermal features such as reflectivity, emissivity, and heat capacity. Therefore, urban space needs appropriateplanning with building arrangement, green walls and land cover replacement for mitigating thermalcomfort in urban area.
