A Bibliometric Analysis and Visualization of Building Decarbonization Research

Abstract

The building sector is responsible for approximately 40% of global energy consumption and carbon emissions, making it a key area of focus in addressing the urgent global challenge of climate change and in achieving the 1.5-degree target. This study concentrated on building decarbonization, using bibliometric and network visualization analyses based on a dataset of 2494 publications retrieved from the Web of Science up to 25 June 2023. Findings revealed a rapid growth in publications, with China being the largest contributor (approximately 31%). Notably, the journals of Cleaner Production and Applied Energy emerged as the most influential journal in this field. Although leadership teams and authors have gained prominence, cross-national collaboration and communication among them remain limited. Furthermore, an analysis of keywords and co-citations revealed that the main research themes and hotspots encompass “energy”, “life cycle assessment”, “storage”, and related “models” and decarbonization “strategies”. As the field progresses, a clear trend toward multidisciplinary integration and diversified research directions and content was observed. Researchers can further concentrate their efforts on countries with historically limited research but substantial emissions, and enhance international collaboration and interdisciplinary integration. Overall, this study offers valuable insights for researchers and facilitates future investigations in the field of building decarbonization.
