This study investigated the thermal sensation of elderly people in Taiwan, older than 60 years, in indoor microclimate at home, and their requirements for establishing thermal comfort. The study was conducted using both a thermal sensation questionnaire and measurement of indoor climatic parameters underlying the thermal environment. Survey results were compared with those reported by Cheng and Hwang (2008, J. Tongji Univ., 38, 817-822) for non-elders to study the variation between different age groups in requirements of indoor thermal comfort. The results show that the predominant strategy of thermal adaptation for elders was window-opening in the summer and clothing adjustment in the winter. The temperature of thermal neutrality was 25.2 degrees C and 23.2 degrees C for the summer and the winter, respectively. Logistically regressed probit modeling on percentage of predicted dissatisfied (PPD) against mean thermal sensation vote revealed that the sensation votes corresponding to a PPD of 20% were +/- 0.75 for elders, about +/- 0.10 less than the levels projected by ISO 7730 model. The range of operative temperature for 80% thermal acceptability for elders in the summer was 23.2-27.1 degrees C, narrower than the range of 23.0-28.6 degrees C reported for non-elders. This is likely a result of a difference in the selection of adaptive strategies.
Taiwan in the last decade has seen a rapid growth in the elderly population in its societal structure, and as such the quality of indoor thermal comfort increasingly concerns the elderly people. This study presents the results from field-surveying elders residing in major geographical areas of Taiwan, and discusses the requirements of these elders for indoor thermal comfort in different seasons. Through a comparison with the requirements by non-elders, this study demonstrates the unique sensitivity of elders toward indoor thermal quality and the selection of adaptive strategies that need to be considered when a thermal comfort zone is attempted in a household of members consisting of different age groups.
本研究调查了台湾 60 岁以上老年人在室内微气候中的热感觉，以及他们对建立热舒适的要求。本研究采用热感觉问卷和测量室内气候参数来研究热环境。将调查结果与程和黄（2008 年，同济大学学报，38 期，817-822）报告的非老年人的数据进行比较，以研究不同年龄组对室内热舒适要求的差异。结果表明，老年人适应热环境的主要策略是夏季开窗通风，冬季调整衣着。夏季和冬季热中性温度分别为 25.2°C 和 23.2°C。对不满意百分比（PPD）与平均热感觉投票的逻辑回归概率建模表明，PPD 为 20%时的感觉投票值对于老年人为 +/-0.75，比 ISO 7730 模型预测的水平低约 +/-0.10。老年人在夏季 80%可接受温度范围内的操作温度为 23.2-27.1°C，比非老年人报告的 23.0-28.6°C 范围窄。这可能是由于适应策略的选择不同所致。
过去十年，台湾社会结构中老年人人口迅速增长，因此室内热舒适质量越来越受到老年人的关注。本研究展示了来自台湾主要地理区域的老年人实地调查的结果，并讨论了他们在不同季节对室内热舒适的要求。通过与非老年人的要求进行比较，本研究展示了老年人对室内热质量的独特敏感性，以及在家庭中成员年龄不同时尝试热舒适区时需要考虑的适应策略的选择。
