对广州地区某校园夏季室外热环境进行了现场测试。在2014年8月至2014年10月期间,对环境参数开展现场测试和问卷调查研究,问卷调查共收到有效问卷1 582份。研究结果表明,广州地区夏季室外中性温度为23.9℃,而期望温度为23.7℃。广州居民对温度变化的敏感与其他地区存在不同程度的区别。可接受热舒适分析表明,90%被测对象可接受的热环境对应的SET*上限为28.54℃,与其他地区可接受温度上限值有明显不同。运用线性回归的方法,建立了当地的热环境评价指标ASV*,为环境设计者提供参考。
Investigations and analysis on outdoor thermal environment were conducted in Guangzhou campuses in summer. Site tests and meanwhile a questionnaire survey were adopted to assess the thermal comfort of subjects from August to October, 2014, and 1,582 effective questionnaires were collected in total. Results showed that neutral temperature was 23.9℃ and the preferred temperature was 23.7℃. Sensitivity to temperature variations in Guangzhou was different from that in other regions. Acceptable thermal comfort analysis indicated that the upper limit of SET* , corresponding to the thermal environment, that could be accepted by 90 % measured objects was 28.54℃, which was distinctly different from the acceptability limit of thermal temperature in other regions. Finally, linear regression was employed to establish ASV* , the local thermal environment evaluation indicator, so as to provide a reference to environmental designers.
