Actual Measurement and Analysis of Winter Thermal Environment in Typical Streets and Alleys in Villages and Towns of Hot Summer and Cold Winter Regions
Eight typical cases from Renshou Town,Nanping City,Fujian Province are selected for actual measurement,the streets and alleys characteristics of different height to width ratios,orientation and plane shape etc are analyzed.The simultaneous changes of air temperature,relative humidity,wind speed and black sphere temperature are compared.The results show that,orientation affects the thermal environment of streets and alleys in winter mainly by way of solar radiation,and its effect is closely related to the cross-sec-tional shape of the streets and alleys.The streets and alleys located in multistory low-density residential areas have higher temperatures than multistory high-density residential areas,and have higher wind speeds.In a multistory building complex,streets and alleys with a flat"T"shape have lower wind speeds and higher tem-peratures.The wind speeds of the streets and alleys with narrow and similar building heights on both sides are higher than those with different building heights on both sides,their thermal environment remains in a com-fortable range for most of the day.
