【摘要】 在双碳目标引领下，北京市建筑领域正处于能源结构深度转型的关键阶段。本文系统梳理了北京建筑能源转型的现状、路径与实践经验。北京市主要通过建筑能效提升、可再生能源替代与能源系统智慧协同三大策略，逐步形成以电能和可再生能源为主体的低碳能源体系。新建建筑严格执行绿色建筑标准，既有建筑广泛推进超低能耗与近零能耗改造；供热领域加快以热泵和电锅炉为主体的新型供热系统重塑；提升终端用能电气化水平，利用智慧管理与数字监测实现能源系统的优化调度。以典型项目分析表明，标准政策与综合技术协同可显著降低建筑碳排放。北京建筑能源转型路径极具示范意义，为超大城市实现建筑领域碳中和提供了可推广的经验与模式。更多还原

【Abstract】 Guided by the dual carbon goals, Beijing’s building sector is undergoing a critical phase of profound energy structure transformation. This paper systematically examines the current status, pathways, and practical experiences of Beijing’s building energy transition. The city primarily employs three strategies-enhancing building energy efficiency, substituting with renewable energy, and achieving intelligent coordination of energy systems-to progressively establish a low-carbon energy system centered on electricity and renewable sources. New buildings strictly adhere to green building standards, while existing structures undergo widespread ultra-low and near-zero energy retrofits. The heating sector is accelerating the restructuring of heating systems centered on heat pumps and electric boilers. Concurrently, the electrification level of end-use energy consumption is being elevated, with smart management and digital monitoring enabling optimized scheduling of the energy system. Analysis of typical projects demonstrates that the synergy between standard policies and integrated technologies can significantly reduce building carbon emissions. Beijing’s building energy transition pathway holds exemplary significance, providing replicable experience and models for megacities to achieve carbon neutrality in the building sector.更多还原
