Modification of Human-Biometeorologically Significant Radiant Flux Densities by Shading as Local Method to Mitigate Heat Stress in Summer within Urban Street Canyons

1 h mean values of the long-wave radiant flux densities 𝐿_𝑖 (𝑖 = down, up, E, S, W, and N) reaching the human-biometeorological reference person from the three-dimensional environment, related to the 1 h peak value of 𝐿_up (𝐿_up,max = 474 W/m²), SSW-facing sidewalk (shaded by tree canopies) of a WNW-ESE street canyon, “Vauban” quarter in Freiburg during typical Central European summer day.
