The thermal adaptation of buildings and their residents is important in extreme cold climates for energy-saving building design. A thermal measurement and a thermal comfort survey were conducted in traditional houses during the winter in the extreme cold climate of the Himalayan region of Nepal. Measurements were taken in 9 houses over 7 days to assess the thermal environment. Thermal comfort surveys were conducted over 4 days, and a total of 1,584 thermal responses were gathered from 36 residents. Passive heating effects were found in houses with thick brick walls and mud roofs. Residents of these houses were highly satisfied with the thermal environment, with 10.7 °C being the mean comfort temperature, which was related to the indoor temperature of the investigated indoor spaces. It can be concluded from these findings that people are well adapted to the thermal environment of traditional vernacular houses, as a result of which the comfort temperature is lower than the thermal comfort standards. Consequently, a significant amount of energy can be saved by passive building design and lowering the indoor temperature setting for heating.

在极端寒冷的气候中，建筑物及其居民的热适应对节能建筑设计至关重要。在尼泊尔喜马拉雅地区的极端寒冷气候下，冬季在传统房屋中进行了热测量和热舒适性调查。在7天内对9栋房屋进行了测量，以评估热环境。在4天内进行了热舒适度调查，从36位居民那里收集了总共1584张热响应。在厚砖墙和泥瓦屋顶的房屋中发现了被动加热效应。这些房屋的居民对热环境非常满意，平均舒适温度为10.7°C，这与所调查的室内空间的室内温度有关。从这些发现可以得出结论，人们很好地适应了传统民居的热环境，其结果是舒适温度低于热舒适标准。因此，通过被动式建筑设计并降低供暖的室内温度设置可以节省大量能源。
