The sub-Himalayan region extends over 2500 km, extending over several countries. Though the effects of climate change is widely anticipated in the diverse but fragile ecosystem of the Himalayas, very less research has been conducted on the indoor environment of the buildings in these regions. In this study, a pre-validated model of 3-storey concrete residential building was used to study the indoor performance and thermal comfort in the face of climate change in the 8 (eight) different hill towns (hill stations) located from west to the east. Rise in ambient and indoor conditions were evident as a part of climate change with colder locations being affected the most. The thermal comfort assessment using both the climate chamber based PMV model and adaptive models revealed the decrease in cold related discomfort and increase in hot related discomfort. On an overall, the indoor conditions improved in these cold locations. The indoor and outdoor thermal condition and thermal comfort plummeted significantly with latitude and elevation. The heating demand in the future climate reduced by about 50-70 % in warmer locations, while the cooling demand increased by as much as 1000-2000 % in cold locations, respectively. Additionally, it was seen that the thermal environment and comfort both declined more rapidly with elevation in the locations lying in the western Himalayas as compared to those in the eastern Himalayas.
次喜马拉雅地区绵延 2500 多公里，跨越多个国家。尽管气候变化的影响在喜马拉雅地区多样化但脆弱的生态系统中广为人知，但针对这些地区建筑的室内环境，研究却很少。在这项研究中，使用经过预先验证的三层混凝土住宅建筑模型，研究了从西到东的 8 个不同山区（山区城镇）在气候变化面前的室内性能和热舒适度。随着气候变化的一部分，环境和室内条件明显上升，受影响最大的是较冷的地区。使用基于气候室的 PMV 模型和适应性模型进行的热舒适度评估表明，与寒冷相关的不适减少，与炎热相关的不适增加。总的来说，这些寒冷地区的室内条件有所改善。室内外热条件和热舒适度随着纬度和海拔的升高而显著下降。在未来气候下，温暖地区的供暖需求减少了约 50-70%，而寒冷地区的制冷需求则增加了 1000-2000%。此外，与位于喜马拉雅东部的地区相比，位于喜马拉雅西部的地区的热环境和舒适度随着海拔的升高下降得更快。
