20年建筑能效与生命周期评估研究全景图，揭示关键方向。
LCA and energy efficiency in buildings: mapping more than twenty years of research
- 结合社会网络分析与文本挖掘，处理8024篇文献摘要。
- 识别出7个核心主题群组，聚焦建材与能效研究。
- 提出语义品牌评分，追踪可持续建筑研究趋势。
生命周期评估（LCA）研究涵盖建筑建材、构件到整体结构的评价，但现有综述未能全面梳理该领域进展，导致学者缺乏明确研究指引。本文旨在填补这一空白，系统映射超过二十年的研究脉络。通过融合社会网络分析与文本挖掘的创新方法，分析了8024篇科学摘要，识别出7个关键主题群组——建筑与可持续性集群（BSCs）。采用语义品牌评分（SBS）指标评估其在建筑与可持续发展讨论中的重要性，并追踪以LCA为核心的演变趋势。主要研究议题集中于建筑建材与能源效率。本文不仅提供了一种高效处理大规模文献领域的新型综述方法，还揭示了新兴及薄弱研究方向，为未来研究指明了关键路径。
原文摘要 · Abstract (English)
Research on Life Cycle Assessment (LCA) is being conducted in various sectors, from analyzing building materials and components to comprehensive evaluations of entire structures. However, reviews of the existing literature have been unable to provide a comprehensive overview of research in this field, leaving scholars without a definitive guideline for future investigations. This paper aims to fill this gap, mapping more than twenty years of research. Using an innovative methodology that combines social network analysis and text mining, the paper examined 8024 scientific abstracts. The authors identified seven key thematic groups, building and sustainability clusters (BSCs). To assess their significance in the broader discourse on building and sustainability, the semantic brand score (SBS) indicator was applied. Additionally, building and sustainability trends were tracked, focusing on the LCA concept. The major research topics mainly relate to building materials and energy efficiency. In addition to presenting an innovative approach to reviewing extensive literature domains, the article also provides insights into emerging and underdeveloped themes, outlining crucial future research directions.
