Abstract: With the advancement of the "dual-carbon" goals, green buildings have become the core direction of transformation and development in the construction industry. As the main source of building energy consumption, electrical systems hold significant potential for energy saving. This study focuses on energy-saving technologies in electrical construction of green buildings, exploring the paths of integrated application and management model innovation. First, the technical indicator requirements for electrical energy saving under the green building evaluation system are analyzed, and the key energy-consuming components of electrical systems are identified. Principles for energy-saving technology selection and integrated design are proposed, and an integration process for energy-saving technologies during the electrical construction phase is established, with feasibility verified through typical case studies. Second, during the construction phase, an innovative path for an integrated management model of electrical construction energy-saving technologies is proposed, based on lifecycle energy-saving management concepts, quality management and process control, and the establishment of multi-party collaboration mechanisms. Finally, an evaluation path incorporating international performance protocols, model comparisons, and post-occupancy evaluation feedback is designed, while introducing optimization directions such as intelligent control, economic incentives, and the linkage of policy standards. Together, these provide systematic solutions and actionable approaches for building long-term energy-saving mechanisms in green building electrical systems, thereby promoting the development of green buildings.
