In recent years, Urban Heat Island (UHI) phenomenon, which causes excessive energy consumption, environmental deterioration, and health damage, has become prevalent in many cities. Urban planners have been challenging to reduce UHI by effective city planning and policies. However, because of the complicated nature of causes in the urban environment changes, it is still challenging to measure their effectiveness on the UHI reduction. Therefore, this study takes Tsukuba city, a planned city, as an example, to assess the effect of landscape composition on Land Surface Temperature (LST) and evaluates the distribution of building height (3D) and functions (e.g., residential, commercial) on LST. This study uses Esri City Engine and ArcGIS software to conduct spatial analysis using remote sensing data, open street map data, and Zenrin data. The regression analysis examines the relationships between LST and land use/cover, building height, building function, and other variables (e.g., distance to the road). Our results show that green space management and control could be significant to harmonize demand growth, environment protection, economic development, and healthy urban establishment. The enhanced theoretical underpinning on sustainable cities can further promote city dwellers' environmental awareness and help the city make an orderly urban development.
