The relationship between thermal environmental parameters and clothing insulation is an important element in improving thermal comfort for the elderly. A field study was conducted on the indoor, transition space, and outdoor thermal environments of 17 elderly facilities in Shanghai, China. A random questionnaire survey was used to gather data from 672 valid samples. A statistical analysis of the data was conducted, and multiple linear regression models were established to quantify the relationships between clothing insulation, respondent age, indoor air temperature, and indoor relative humidity. Results indicated that the average thermal insulation of winter and summer clothing is 1.38 clo and 0.44 clo, respectively, for elderly men and 1.39 clo and 0.45 clo, respectively, for elderly women. It was also found that the thermal insulation of winter clothing is linearly correlated with age, and that there were seasonal differences in the relationship between clothing insulation and the environment. During winter, the clothing insulation is negatively correlated only with indoor temperature parameters (air temperature and operative temperature) for elderly males, while it is negatively correlated with indoor temperature parameters as well as transition space and outdoor air temperature for elderly females. In summer, clothing insulation for both elderly males and females is negatively correlated with outdoor temperature, as well as indoor temperature parameters (air temperature and operative temperature). The thermal insulation of summer clothing is also negatively correlated with transitional space temperature for males.
热环境参数与服装隔热之间的关系是提高老年人热舒适度的一个重要因素。在中国上海，对17家老年设施的室内、过渡空间和室外热环境进行了实地研究。采用随机问卷调查的方式，从672个有效样本中收集数据。对数据进行了统计分析，并建立了多元线性回归模型，以量化服装隔热、受访者年龄、室内气温和室内相对湿度之间的关系。结果表明，老年男性冬夏服装的平均隔热值分别为1.38 clo和0.44 clo，老年女性分别为1.39 clo和0.45 clo。研究还发现，冬季服装的隔热值与年龄呈线性相关，服装隔热与环境之间的关系存在季节差异。在冬季，老年男性的服装隔热仅与室内温度参数（气温和操作温度）呈负相关，而老年女性的服装隔热与室内温度参数以及过渡空间和室外气温呈负相关。在夏季，老年男性和女性的服装隔热均与室外温度以及室内温度参数（气温和操作温度）呈负相关。男性夏季服装的隔热也与过渡空间温度呈负相关。
