摘要
居住区的室外空间是老年人进行户外活动的主要场所,其良好的热舒适环境显得尤为重要。以天津市3种典型布局形式的老旧居住区为研究对象,通过现场实测和问卷调研,了解老年人的热感觉并探析小区内不同位置热环境参数的分布规律及存在的问题。同时确定了春季老年人主观热感觉投票值与基于实测值的热舒适指标生理学等价温度之间的函数关系,进一步得到老年人的热中性生理学等价温度约为21.3℃,其热舒适生理学等价温度范围为16.5~26.2℃。最后选取典型居住区对其空间布局进行优化设计,采用Phoenics和Ecotect软件对优化后的室外空间热环境进行模拟与分析,从而提出基于热舒适的居住区室外空间设计宜采用在建筑来风向一侧围合,内部为行列式分布的混合式布局方式。
As a main place in which to carry out outdoor activities for the elderly,it is particularly important for the outdoor space of the residential area to have a good thermal comfort environment.Taking three typical layouts of the old residential areas in Tianjin as the research object,the field measurement and questionnaire survey were performed to understand the thermal sensation of the elderly and analyze the distribution rule and existing problems of the thermal environment parameters at different locations in the community.At the same time,the function relationship between the thermal sensation vote and the physiological equivalent temperature(a kind of thermal comfort index)based on the measured value was determined.The results show that the thermal neutral physiological equivalent temperature of the elderly is about 21.3℃,and that the thermal comfort range is 16.5~26.2℃.Finally,a spatial layout optimization of the typical residential area was conducted,with the Phoenics and Ecotect software used to simulate and analyze the thermal environment of the optimized outdoor space.Thus,it is suggested that the outdoor space design of a residential area,based on the outdoor thermal comfort,should adopt the mixed layout mode in which the building is surrounded in wind direction and that the interior of the residential area should be arranged in a row.
