Abstract

In the context of climate change and the depletion of traditional energy sources, it is significant to explore passive building technologies that are suitable for specific climatic and geographical conditions. This paper reviews strategies for retrofitting sunspaces in vernacular dwellings on the Qinghai-Tibet Plateau, focusing on enhancing solar gain and addressing cultural preservation challenges. The unique solar utilization characteristics and architectural forms are discussed, highlighting the need for tailored retrofit technologies. The paper analyzes the technological typology of sunspaces, including sun passageways, sunrooms, and sun courts, and evaluates their performance in terms of temperature rise, economic viability, user acceptance, and cultural adaptability. Implementation barriers, such as technical, social, and economical constraints, are identified, and emerging solutions are proposed to overcome these challenges. The study aims to provide insights for future retrofit projects that balance thermal performance improvement with cultural integrity preservation in high-altitude region.
