基于UTCI的寒地夏季商业街室外热舒适研究

ON THE OUTDOOR THERMAL COMFORT OF COMMERCIAL STREET IN COLD REGIONS IN SUMMER BASED ON UTCI

优化商业街的热环境可以提高人体舒适度。文中采用问卷与实测的方法,对夏季寒地商业街研究得出,中性UTCI温度为26℃,行人对有阴影遮挡的商业街感觉舒适,对空旷的广场、东西向和柏油路旁的商业街感觉不舒适,影响热感觉的因素有空气温度、黑球温度和人的性别、年龄。

Optimizing the thermal environment of the commercial street can improve human comfort.The questionnaire and in-situ measurement are used to study the commercial streets in cold regions in summer.The results show that the neutral universal thermal climate index(UTCI)temperature is 26℃.Pedestrians feel comfortable in shadowed commercial streets,whereas uncomfortable in open squares,east-west orientation streets,and asphalt commercial streets.The factors that affect thermal sensation are air temperature,black globe temperature,gender,and age.
