Thermal comfort standards are essential to ensure comfortable and enjoyable indoor conditions, and they also help in optimizing energy use. Thermal comfort studies, either climate chamber‐based or field investigation, are conducted across the globe in order to ascertain the comfort limits as per the climatic and other adaptive features. However, very few studies are conducted when the occupants are subjected to a stressed condition, like the COVID‐19 lockdown, which may not only have the health impacts but also have psychological impacts on the adaptation. In this paper, we present the results of the online study conducted regarding the status of thermal comfort during the COVID‐19 lockdown in India. A total of 406 complete responses were collected from subjects located across 3 different climatic regions of India, that is, cold climate, composite climate, and hot and humid climate. Variations in clothing insulation, thermal sensation, and preference were noted across the different climatic regions. We also present the variation in opening of windows and running of fans with the variation in outdoor mean air temperature. The self‐judged productivity, comfort, desire to go outdoors, and effectiveness of working from home were seen to vary with the increase in the days of lockdown.

印度不同气候地区居民的热舒适度研究——COVID-19封锁的影响


热舒适标准对于确保舒适和愉快的室内条件至关重要，并且还有助于优化能源使用。在全球范围内进行基于气候室或现场调查的热舒适性研究，以便根据气候和其他适应性特征确定舒适度极限。然而，很少有研究是在居住者处于压力条件下进行的，例如 COVID-19 封锁，这不仅可能对健康产生影响，而且还会对适应产生心理影响。在本文中，我们介绍了印度 COVID-19 封锁期间热舒适状况的在线研究结果。总共收集了 406 份完整回答，来自印度 3 个不同气候区的受试者，即寒冷气候、复合气候和湿热气候。不同气候地区的服装隔热性、热感和偏好存在差异。我们还展示了窗户打开和风扇运行随室外平均气温变化的变化。人们对自我评价的生产力、舒适度、户外活动的渴望以及在家工作的有效性随着封锁天数的增加而变化。
