تاثیر روانی و جسمانی فضای سبز شهری بر روی آسایش حرارتی در فضای باز در طول فصل تابستان در هلند

Our results demonstrate that green infrastructure improves generally perceived thermal comfort. People evaluated green urban spaces as the most thermally comfortable spaces which was in line with the physical thermal investigations. Physiological equivalent temperature (PET) in parks on average was 1.9 K lower than in the city centre and 5 K lower than in the surrounding grasslands during the hottest period of the day. Thermal variance between parks was significantly influenced by tree canopy cover (mean radiant temperature p = 0.00005) and upwind vegetation cover (air temperature p = 0.013), not significantly for park size.
