Exploring the appropriate technology for green renovation of rural buildings incorporating regional culture: Taking the renovation of village houses in Conghua, Nanping, Guangzhou as an example

In view of the rising energy consumption of rural buildings in recent years and the neglect of the connection with regional architectural culture in the construction process, this study explains the connotation and representation of regional culture based on the theoretical tool of cultural regional character, and constructs a suitable technical system for green transformation of rural buildings incorporating regional culture from five aspects, which are regional character creation, outdoor environment improvement, envelope structure performance optimization, indoor environment quality improvement, and renewable energy utilization. Based on the construction of this system, this study takes the renovation of the village residence in Nanping, Conghua, Guangzhou as an example, and explores the ways to achieve green and sustainable development in the renovation of rural buildings in the Lingnan Guangfu area with the guidance of the system and method of integrating regional culture and modern green building technology. The study compares the buildings of Nanping village residence in Conghua, Guangzhou, before and after the renovation, and finds that after the renovation, the building consumes less energy, the spatial quality is improved, and the overall spatial and stylistic expression is more in line with the regional cultural characteristics, which provides theoretical and practical references for the green renovation of rural buildings.
