摘要
城市道路照明系统在“双碳”背景下成为低碳基础设施转型的重要对象。现研究多聚焦于运行阶段能耗碳排放,忽视材料制造、施工建设与运行维护等生命周期其他环节,导致碳足迹评估偏差。本文基于ISO 14067标准与生命周期评价方法,构建覆盖原材料获取、制造安装至运行维护的碳排放核算模型,结合南京六条典型道路的实地数据与工程参数,系统识别城市道路照明的主要碳源构成与影响因子。在此基础上,提出智能控制优化、灯具参数调整与照明布设重构等分型低碳化策略,构建“一路一策”协同减排路径体系并开展模拟验证。研究成果可为城市道路照明系统绿色更新提供方法框架与技术支撑,也为政策制定、招评标机制优化及低碳城市道路照明建设提供实证依据。
Urban road lighting systems have emerged as key targets for low-carbon infrastructure transition under the dual-carbon policy framework.Current research predominantly focuses on carbon emissions during the operational phase,while neglecting emissions associated with material manufacturing,construction,and maintenance phases,thereby leading to incomplete carbon footprint assessments.This study,grounded in ISO 14067 and Life Cycle Assessment(LCA)methodology,establishes a carbon emission accounting model encompassing raw material acquisition,product manufacturing,installation,and operational maintenance stages.Based on empirical data from six representative roads in Nanjing,the study identifies major carbon sources and influencing factors in urban lighting systems.A set of differentiated low-carbon strategies,such as intelligent control optimization,lamp parameter adjustment,and lighting layout redesign,is proposed and integrated into a“road-specific”emission reduction framework.Simulation results validate the effectiveness of the proposed approach.The findings provide a methodological foundation and technical support for the green upgrade of urban lighting systems,while also offering empirical evidence for policy-making,bidding evaluation reform,and sustainable lighting infrastructure development.
