The building industry is responsible for considerable environmental impacts due to its consumption of resources and energy, and the production of wastes. Circular Economy (CE), a new paradigm can significantly improve the sustainability of this sector. This paper performs a quantitative scientific evolution analysis of the application of CE in the building sector to detect new trends and highlight the evolvement of this research topic. Around 7000 documents published 2005 to 2020 at Web of Science and Scopus were collected and analyzed. The bibliometric indicators, network citation, and multivariate statistical analysis were obtained using Bibliometrix R-package and VOSviewer. The co-occurrence analysis showed five keyword-clusters, in which the three main ones are: (i) energy and energy efficiency in buildings; (ii) recycling, waste management and alternative construction materials; (iii) sustainable development. The analysis showed that researchers pay close attention to “sustainability”, “energy efficiency”, “life cycle assessment”, “renewable energy”, and “recycling” in the past five years. This paper highlights that (i) the development and use of alternative construction materials; (ii) the development of circular business models; (iii) smart cities, Industry 4.0 and their relations with CE, are the current research hotspots that may be considered as potential future research topics.

建筑业由于消耗资源和能源以及产生废物而对环境造成重大影响。循环经济（CE）是一种新的范例，可以显着提高该行业的可持续性。本文对CE在建筑领域的应用进行了定量的科学演化分析，以发现新趋势并突出该研究主题的发展。收集并分析了2005年至2020年在Web of Science和Scopus上发表的大约7000份文档。使用Bibliometrix R-package和VOSviewer获得了文献计量指标，网络引用和多元统计分析。共现分析显示了五个关键字类，其中三个主要类是：（i）建筑物的能源和能效；（ii）回收，废物管理和替代建筑材料；（iii）可持续发展。分析表明，研究人员在过去五年中密切关注“可持续性”，“能源效率”，“生命周期评估”，“可再生能源”和“回收”。本文着重指出：（i）替代建筑材料的开发和使用；（ii）发展循环业务模式；（iii）智慧城市，工业4.0及其与CE的关系是当前的研究热点，可以被视为潜在的未来研究主题。本文着重指出：（i）替代建筑材料的开发和使用；（ii）发展循环业务模式；（iii）智慧城市，工业4.0及其与CE的关系是当前的研究热点，可以被视为潜在的未来研究主题。本文着重指出：（i）替代建筑材料的开发和使用；（ii）发展循环业务模式；（iii）智慧城市，工业4.0及其与CE的关系是当前的研究热点，可以被视为潜在的未来研究主题。
