Appeal point
Capable of simulating the thermal environment in the city block considering the topography
Thermal environment can be quantitatively evaluated, and thermal environment assessment for urban redevelopment becomes possible
Summary
Latitude, longitude, altitude, geology as topographical data, wind direction, wind speed, temperature, atmospheric pressure, humidity as meteorological data are acquired, a predetermined area is considered in a three-dimensional space including multiple three-dimensional objects, and meteorological data after a predetermined time is calculated.
The three-dimensional space is composed of multiple grids, and the attribute data including the view factor between each grid, the area of each grid, the reflectance, and the temperature is acquired.
The thermal radiation is calculated based on each of these data, and the flux and pressure fluctuation between the three-dimensional object and the atmosphere in the three-dimensional space are calculated to obtain meteorological data.
