Abstract |
This study elucidated the difference of microclimate between the tree-covered road and the building-surrounded road. Dry bulb temperature, wet bulb temperature, relative humidity, globe temperature, air velocity, illuminance level, irradiance of UVA and UVB were investigated and compared the difference between two roads. The results of investigation revealed that the dry buld temperature was 33.0oC in tree-covered road and 34.8oC in building surrounded road. The differences between two roads were 0.9oC in wet bulb temperature, 4.0oC in globe temperature, 0.2m/s in air velocity, 33,228 Lux in illuminance level, and 9260 mW/m2 in UVA and 363 mW/m2 in UVB irradiance, respectively. It is obvious that urban greening mitigates hot microclimate in urban area. |
