ABSTRACT

Somatosensory comfort is mainly determined by the Temperature and Humidity Index (THI) with Wind Efficiency Index (WEI), but this conventional usage of these indicators does not capture the age-related differentials. Here we resolved this gap with a modification of the climatic comfort definition and method in a national standard, denoted as the Relative Climate Sensitive Index (RCSI), which incorporated the age-related vulnerability scores determined through online questionnaires with a scoring method, for each of the age-related and adaptive climatic comfort responses to changes in residence with Beijing-Tianjin-Hebei (BTH) region as an example. First, the result showed that the human comfort of living environment decreased with age in the BTH region, implicating age obviously impacted comfort, and weak adaptability made the elderly the relatively most high-risk group – their suitable region was less than a quarter of the whole study region. Second the adverse effects of persistent hot weather on comfort, indicating global warming as the leading driver of dwindling comfort over recent years. As the warming was more significant in the southeastern part, all these forces combined had there a hotspot, appealing for extra attention. Last this improved evaluation accorded with actual situation to captured high-risk groups with their distributions.

摘要

体感舒适度主要由温湿度指数（THI）与风效率指数（WEI）共同决定，但是这些指标的常规用法无法捕获与年龄相关的差异。在这里，我们通过修改国家标准（称为相对气候敏感性指数（RCSI））中的气候舒适度定义和方法，解决了这一差距，该标准将通过在线问卷确定的与年龄相关的脆弱性评分与评分方法相结合京津冀地区与年龄相关的适应气候适应对居住变化的影响 首先，结果表明，BTH地区的人们对居住环境的舒适度随着年龄的增长而降低，这暗示着年龄明显影响了舒适度；适应性较弱使老年人成为相对高风险的人群，他们的合适区域不到整个研究区域的四分之一。其次，持续炎热的天气对舒适性的不利影响，表明全球变暖是近年来舒适性下降的主要驱动力。由于东南部的变暖更为严重，所有这些力量加在一起就形成了一个热点，呼吁人们格外注意。最后，这种改进的评估符合实际情况，以捕获高风险群体及其分布。由于东南部的变暖更为严重，所有这些力量加在一起就形成了一个热点，呼吁人们格外注意。最后，这种改进的评估符合实际情况，以捕获高风险群体及其分布。由于东南部的变暖更为严重，所有这些力量加在一起就形成了一个热点，呼吁人们格外注意。最后，这种改进的评估符合实际情况，以捕获高风险群体及其分布。
