The renovation of old buildings provides an important approach to energy saving and emission reduction with low economic costs. The current important issue remains how to determine the optimal cost-effective technical path for a specific project, although there are a large number of retrofit technologies to choose from. Based on a systematic perspective, this paper conducts a quantitative analysis of the environmental and economic benefits of building renovation, and compares and studies the role and challenges of different countries in the process of recycling waste building materials and technological innovation to extend the life of buildings. Through the use of VOSviewer, 1402 papers from the Web of Science core collection database were visualized, analyzed, and deduced, and the research context and development trends of architectural renovation were sorted out and presented. Finally, this article discusses the status and application process of existing building renovation technologies, including the current obstacles that need to be resolved. It puts forward a vision for the future development of building renovation, emphasizing that top-down guidance is essential to future carbon neutral goals.
旧建筑改造提供了一种具有低成本经济效益的节能减排的重要途径。尽管有大量的改造技术可供选择，但目前仍存在一个重要问题，即如何为特定项目确定最佳的具有成本效益的技术路径。基于系统的观点，本文对建筑改造的环境和经济效益进行了定量分析，并比较和研究了不同国家在回收废弃建筑材料和技术创新以延长建筑物寿命的过程中的作用和挑战。通过使用 VOSviewer，对来自 Web of Science 核心集数据库的 1402 篇论文进行了可视化、分析和推理，梳理和呈现了建筑改造的研究背景和发展趋势。最后，本文讨论了既有建筑改造技术的现状和应用过程，包括目前需要解决的障碍。它为建筑改造的未来发展提出了一个愿景，强调未来的碳中和目标需要自上而下的指导。
