Abstract

As a significant component of China's historical architectural heritage, traditional dwellings in the Liangshan region offer a wealth of ecological construction experience. However, due to the age-old limitations of traditional construction techniques, the indoor thermal environment of these dwellings during winter is a salient issue. This paper investigates the current status of the indoor thermal environment in winter using a multifaceted research method that incorporates Climate Consultant climate analysis software, on-site measurements, numerical simulation and theoretical analysis. The study focuses on the Aqiu Lajia, a representative traditional house from Sijiji Village, to provide a case study for analysing and optimising the indoor thermal environment. The study's findings indicate that enhancing the thermal performance of the enclosure structure can lead to an increase in indoor temperature ranging from 2.4℃ to 3.2℃, achieved through the incorporation of thermal insulation layers in the roof and wall sections.Furthermore, the simulation of various building orientations revealed that the south-eastern 15° orientation is effective in reducing wind speed and pressure during winter months, thereby enhancing the natural ventilation effect. The transformation of traditional single-glazed windows into double-glazed windows has been shown to increase indoor temperature by up to 2.69°C whilst simultaneously enhancing thermal insulation performance.The findings of this study provide a scientific basis and technical support for the conservation, protection and renewal of traditional houses in the Liangshan area, and represent a significant theoretical and practical contribution to the sustainable protection and renewal of traditional buildings.
