Abstract

With the continuous development of urbanization in our country, the contradiction between the protection of traditional village heritage architecture and the development of modern urban lifestyle is becoming increasingly prominent. With the introduction of China's rural revitalization strategy, improving the rural living environment, promoting sustainable development, utilizing renewable energy for power supply, and achieving low-carbon architecture have become particularly important. This article investigates the relationship between solar energy system and site layout in illustrative historic buildings, and uses thermal-economic methods for feasibility analysis of such old building retrofitting program toward nearly zero energy construction. The preliminary results indicate that integrating solar panel roof with old building body for renewable energy exploitation can achieve good economic benefits while reducing carbon dioxide emissions. This work provides reference insights into the sustainable transformation of traditional rural heritage conservation buildings in our country and proposes feasible solutions to reconcile the contradiction between the preservation of traditional architectural heritage and sustainable modernization demands.
