In community planning at neighborhood scale, a long-term vision with consideration of future climate change impact becomes increasingly important. This study demonstrated the projections of future build environment image and weather conditions based on SSP/RCP in an urban center neighborhood in Nagoya City and conducted thermal environment simulation of those 3D models. The result of the simulation of SSP5-8.5 (Fossil-fueled development scenario), which we assumed it for its future image that more high-rise buildings will be constructed by the end of the 21st century, confirmed that the neighborhood thermally deteriorated at noon in summer due to both the temperature rise and the reflections of sunlight from the building sides.
