Labor shortage and low labor productivity are critical issues in the construction industry. Robotics, as a powerful technology to improve productivity in the digitization era, is being used to assist in addressing these problems. Particularly in recent years, interest in construction robotics research has risen remarkably. To gain a deeper understanding of this burgeoning research field, this study provides a bibliometric analysis of 498 related papers retrieved from WoS (Web of Science). Performance analysis and science mapping were used in the paper to identify the research trends, relationship among authors, top publication sources, regional activities, as well as knowledge base and dominant research sub-fields. The results indicated that the number of papers focusing on construction robotics has been continuously growing since 2013. "Automation," "system," and "design" have been the most addressed topics in construction robotics. The findings are indicative of identifying the deficiencies in existing research and provide directions for future research. Those include greater attention paid to the experimental results of on-site construction robots, while ignoring the impacts of practical construction situations, and the development of off-site construction robots needs more support. For theoretical research, there is a lack of studies on human–robot collaboration workflow and management models. Therefore, the study would be valuable in providing practitioners and researchers with a better perspective on the development of construction robotics and facilitating the building of the intellectual wealth of robotics in the construction industry. Our study analyzed 498 papers related to construction robotics from 1974 to 2022 through bibliometric approaches (mathematical and statistical methods). The study counted the numbers of construction robotics papers by year, identified most active scholars and top publication sources, and analyzed the relationship among regions. Most importantly, the paper identified the knowledge base of the research field of construction robotics and reviewed various relevant studies from theoretical and practical application perspectives.

[Display omitted] • A comprehensive overview of NZEBs is conducted by using bibliometric techniques. • Hot research topics of NZEBs are identified through keyword co-occurrence analysis. • The research trend, key journals, publications, authors, and countries are analyzed by co-citation analysis. • The thematic evolutionary analysis of NZEBs was investigated using SciMAT tool. This study aims to provide a comprehensive overview of three-decade research developments in the field of Net-Zero Energy Buildings (NZEBs) by using bibliometric analysis techniques. The specific objectives of this paper are to: (1) identify the most influential researchers, sources, and countries in this field; (2) identify the main thematic research focus areas and hot topics in the field; and (3) analyze the thematic evolution of NZEBs. VOSviewer software was used to realize the first two objectives while to meet the third objective, the SciMAT tool was employed to examine the thematic evolution of the field within three sub-periods (1995–2005; 2006–2015; 2016–2022). The results indicate that the main thematic areas of the field were initially limited to a few themes including 'environmental impact', 'green buildings', 'building materials', and 'fuel cells', and it expanded in the next periods by encompassing more themes. The results also showed that the field has now reached a certain level of consolidation by acknowledging the significance of three major themes: (1) buildings' energy conservation, (2) energy production and energy storage, and (3) methodological approach. Nevertheless, the evolutionary analysis points out that the field is still expanding with several themes newly emerged such as 'electric vehicles', 'zero-emission neighborhood' and 'smart buildings'. The findings offer a status-quo overview and critiques of research developments in NZEBs as well as emerging themes in the field that should be investigated by future studies. [ABSTRACT FROM AUTHOR]
