Trends and Interdisciplinarity Integration in the Development of the Research in the Fields of Sustainable, Healthy and Digital Buildings and Cities

This article provides a thorough bibliometric analysis of significant research trends in sustainability from 1988 until now, focusing on sustainable, healthy and digital buildings and cities. It exemplifies how research emphasis has shifted from explicit ecological investigations to nature-based solutions and city greening programs, with a rising interest in the many responsibilities of urban stakeholders in attaining sustainability. Despite weak integration at the literature and author cooperation levels, the “healthy buildings and cities” topic indicates promise for multidisciplinary integration. The “digital buildings and cities” topic, on the other hand, presents a more particular concern with strong cross-cluster collaboration and significant integration possibilities. Global relevance has been demonstrated through research on “sustainable buildings and cities,” mainly in journal papers. This topic’s study clusters show remarkable synergy across management, transportation, ecology, remote sensing and environmental engineering domains. In comparison to “healthy buildings and cities” and “digital buildings and cities” topics, the study of “sustainable buildings and cities” demonstrates a deeper level of interdisciplinary integration, highlighting the significant potential for further exploration within sustainability science research. This study emphasizes the ongoing worldwide relevance of sustainability science research and identifies significant opportunities for multidisciplinary integration across the investigated subjects.
