Indoor photothermal environment in traditional Miao dwellings in western Hunan province: Field measurements, data simulation, and mitigation strategies

Abstract

Rapid urbanization and population growth have escalated demands on the built environment, quality of life, and energy consumption. Consequently, the academic community has delved into the exploration of design methods, construction techniques, building materials, and other climate adaptation strategies, particularly focusing on traditional houses. This study examines the indoor photothermal environment and energy consumption of traditional Miao dwellings in Xiangxi Tujia and Miao Autonomous Prefecture, Hunan Province, China. Through monitoring and simulation, the paper investigates the compatibility between the dwellings and their surrounding environment, shedding light on the efficacy of traditional Miao houses in adapting to local climatic conditions. The findings reveal notable improvements in indoor temperature and humidity levels within typical Miao dwellings, showcasing enhanced climate adaptability compared to the outdoor environment. Nonetheless, the study highlights inadequacies in the indoor natural light environment of these dwellings, necessitating the introduction of light wells to meet contemporary standards. By summarizing the strengths and weaknesses of the indoor photothermal environment in traditional Miao houses in western Hunan Province, this research further evaluates the adaptability of local houses to the regional geographic climate. Additionally, the study offers targeted recommendations to address the identified weaknesses.
