To provide a hot heat and wind environment information generation device and a hot heat and wind environment information generation method capable of grasping prediction information of a hot heat and wind environment for each local region in real time, a
route retrieval device and a
route retrieval method.SOLUTION: A hot heat and wind environment information generation device 21 includes a surface temperature information calculation part 214 and a hot heat and wind environment prediction part 216a. The surface temperature information calculation part 214 acquires information obtained by calculating a temperature of an outer wall surface of an architectural structure and a temperature of a ground surface within an object area in each
material quality as information of surface temperature for each object date and hour within the object area at each position. The hot heat and wind environment prediction part 216a generates prediction information of a hot heat and wind environment in each position in the object date and hour within the object area by executing thermal fluid analysis
processing on the basis of the information acquired by the surface temperature information calculation part 214.SELECTED DRAWING: Figure 1
