Sustainable Renovation and Low-Energy Retrofitting of Houses in Rural Areas of Southern China

摘要

This article focuses on the low-energy retrofit in the context of rural areas in southern China, where countless houses are being renovated to enhance their facade appearance. It explores the feasibility of the integration of present facade renovations with energy retrofit strategies to turn this vanity project into a sustainable renovation project to address the severe issue of climate change in China. Treating the Passive House Planning Package as a research tool, it examines the effect of each retrofit strategy on the energy performance of the rural house across different climatic regions in southern China, and regional solutions are provided for different climate zones through parametric studies to achieve the Passivhaus energy standard and beautify the housing at the same time.
