With the purpose of clarifying the energy-saving influencing factors of the participants in the construction project, qualitative analysis and scientific measurement analysis were combined in this paper to define and identify the energy-saving influencing factors of the construction project lifecycle. First, a qualitative analysis of the research literature of the natural science index (SCI) and social science citation index (SSCI) databases was conducted through a combination of literature analysis and expert interviews, constructing a list of the energy-saving influencing factors in the lifecycle of construction projects. Second, the knowledge map of the energy-saving research literature of construction projects in the past 20 years from the Web of Science (WOS) database was drawn through Citespace. Then the hotspots of energy-saving research in international construction projects were identified through keyword co-occurrence map as energy saving, energy efficiency, and energy consumption. The main research subjects were divided into four categories: energy-saving management and incentive policies, project users’ energy-saving behaviors and awareness, various energy-saving new materials and technologies, and energy-saving management and control at the operation and maintenance stage. Next, nine main clusters on energy-saving research were identified through cluster analysis, mainly distributed in various energy-saving technology research, energy-saving behavior and power research of owners and residents, policy and regulation research, and energy-saving management and control research in the operation and maintenance stage. Finally, the knowledge mapping analysis results were classified and defined according to the action scope of each stage of the construction project, and the identification of the energy-saving influencing factors in the construction project lifecycle was completed.

基于知识图谱的建设项目全生命周期节能影响因素识别

为了明确建设项目参与方的节能影响因素，本文将定性分析和科学计量分析相结合，对建设项目全生命周期的节能影响因素进行界定和识别。首先，通过文献分析和专家访谈相结合，对自然科学索引（SCI）和社会科学引文索引（SSCI）数据库的研究文献进行定性分析，构建节能影响因素列表。建设项目的生命周期。其次，通过Citespace绘制了Web of Science（WOS）数据库中近20年建设项目节能研究文献的知识图谱。然后通过关键词共现图将国际建设项目的节能研究热点确定为节能、能效和能耗。主要研究课题分为节能管理与激励政策、项目用户节能行为与意识、各类节能新材料与技术、运维阶段节能管控四类。 . 其次，通过聚类分析确定了9个主要的节能研究集群，主要分布在各类节能技术研究、业主和居民节能行为与用电研究、政策法规研究、节能管控研究等。运维阶段的研究。最后，
