Unraveling the Knowledge Roadmap of Building Policy Mixes: A Scientometric Analysis

Abstract

Improving energy efficiency and reducing carbon emissions from buildings are crucial for achieving sustainable development. To realize these goals, it is essential to adopt a policy mix. However, despite much effort in this field, there is a lack of comprehensive understanding on building policy mixes (BPMs), which challenges building sustainability. To address this research gap, this study attempted to uncover the knowledge landscape of BPM through scientometric analysis. By employing methods such as keywords co-occurrence analysis, clustering analysis, co-citation analysis, and research trend analysis, this study systematically examined the current status, hot topics, underlying knowledge framework, knowledge domains, and frontiers of BPM research. The findings revealed that the existing BPM research primarily focuses on various aspects, including policy-related topics such as building energy efficiency policies and policy instruments, as well as topics like green affordable housing, hindering factors, carbon pricing, use obligation, construction waste reduction, and sustainable construction methods. Furthermore, the analysis identified research frontiers in BPM, encompassing policy considerations (e.g., building efficiency policy, split incentive, carbon tax, and carbon pricing), energy-related aspects (e.g., consumption, green transition), political dimensions (e.g., governance, management), building-related factors (e.g., green building, retrofitting), the innovation system, and the evolutionary game. Based on these findings, this study suggests that future research in BPM can deepen insight into interdisciplinary policy mixes by focusing on policy strategies, processes, and features. This study contributes to a holistic understanding of BPM and offers insightful guidance for both researchers and practitioners seeking to advance sustainable practices in the building sector.
