Appeal point
The heat index (WBGT: heat stroke risk) can be calculated because the radiant temperature in the city block can be calculated.
The thermal environment can be quantitatively evaluated, and the thermal environment assessment for urban redevelopment becomes possible.

Summary
The urban space is considered as a three-dimensional space containing multiple solid objects, and the space is constructed with multiple grids.
The thermal radiation is calculated based on the attribute data including the view factor between each grid, the area of each grid, the reflectance, and the temperature.
According to this simulation, the heat index distribution according to the time (sunlight direction) of the urban space can be expressed, and it can be used as a thermal environment assessment for urban redevelopment.
