Human subject experiments were conducted to investigate the influences of thermal load and thermal sensation under various outdoor radiation environments. The experiments were conducted at locations simulating the application of ground surface materials with different solar reflectance, tall trees, green walls, hedges, and retro-reflective materials. The results revealed that a quantitative evaluation of the heat transfer between the human body and the surrounding environment using the human thermal load may be connected to the thermal sensation felt under various radiation environments. The improved effects of the thermal sensation by the decrease in reflected solar radiation from the ground, the decrease in transmitted solar radiation from the sky, the decrease in infrared radiation from the wall surface, the decrease in reflected solar radiation toward the human body from a window surface, and the shielding of infrared radiation from the ground surface were quantitatively evaluated based on the human thermal load.
