This paper presents a research agenda for Social Network Analysis (SNA) in Digitalization in Sustainable Built Environment research (DSBE). The paper contains a description of SNA, and reviews the use of SNA in DSBE research. Also, the paper identifies future research challenges that SNA can help resolve. A literature review of DSBE finds that of 506 articles in 36 journals, only 1 article includes SNA. This is surprising, given the growing interest in SNA in digitally related fields. We review the 506 DSBE articles and analyze how SNA can contribute to the field. To understand how SNA can be used in DSBE research, we also analyze how SNA has been applied in Digitalization in Built Environment research that is not focused on sustainability. Findings are that SNA can be a useful and powerful tool, because it can help in analysis of how multiple actors interact, which is a common theme in built environment research. An example is that architects, contractors, and developers are separate actor groups that can improve sustainable solutions through networked cooperation. Another area in which SNA can advance research is in the study of how actor networks of companies or people relate to networks of data or physical buildings or sensors. An example is that actors may change their behavior based on sensor data, and SNA can study sensor data networks and actor behavior networks as interconnected layers. Methodological advances are key to advancing research to meet sustainability challenges. Specifically, SNA can make it possible for the built environment area to advance sustainability and digitalization research, because SNA has a rich array of empirical and conceptual tools for the study of networks.
