SPATIAL DISTRIBUTION OF THERMAL COMFORT FOR PEDESTRIANS WITHIN A LOW-RISE RESIDENTIAL DISTRICT NEAR WET AREA

Spatial variability of thermal comfort for pedestrians in a low-rise residential district was evaluated based on a mobile observation. The observation was conducted in August within a residential district near a tidal flad in Narashino, Chiba. The observation was taken place totally for 12 times among 2 days to obtain their ensemble characteristics to extract the local effect. Spatial variation of globe temperature was observed to be more than 3.5 degree, which is attributed to the effects from wet area, variability of vegetation distribution and geometry of the district. Wet flow from the wet area penetrated around 100m inland in case the major streets are perpendicular to the flow although it exceeded 300m in case the major streets are parallel to the flow.
