近年來隨著氣候極端變遷與能源匱乏且價格攀升，各國政府與企業積極開發新能源技術與提升能源使用效率。雖然國際標準組織（ISO）於2011年6月15日公告ISO50001能源管理系統標準，但企業將面對的如何有效提升能源使用效率、建立能源績效指標等難題。由於電腦資訊科技進步快速，帶動網路通訊產品需求數量與製造所需使用能源皆相對大幅增加。本研究探討某網路通訊產品公司案例，以能源整合實務模式，提升ISO50001能源管理系統之能源使用效率並進行ISO50001能源管理系統國際認證。根據研究結果，應用本模式提升該企業年度能源績效指標之整體用電密集度相較於基準年下降21.5%並通過ISO50001國際認證。建立能源整合實務模式導入ISO50001能源管理系統，提供空調、照明和綠能等等能源解決方案與資料庫，有效協助網路通訊企業提升能源使用效率並完成ISO50001能源管理系統國際認證。未來對其他不同產品或高能耗企業值得更多相關性研究。

Because of recent extreme climate change and rising energy prices, worldwide governments and businesses have actively to improve energy efficiency. The rapid development of computer and information technologies has spurred high demand for networking products, thereby substantially increasing energy consumption involving the production of networking products. This research conducted a case study of a networking-product manufacturing company, which used an integrationenergy- practice (IEP) model to improve energy efficiency in ISO 50001 energy management system and underwent ISO 50001 certification. According to the study results, the IEP model improved the energy efficiency, as represented by the overall company energy use intensity (EUI) of the annual energy performance indicators (EnPIs) for the company, reducing this measure by 21.5% compared with the base year. Using the IEP model to implement ISO 50001 energy management systems effectively facilitates networking enterprises in improving energy efficiency, identifying energysaving solutions, and obtaining ISO 50001 international certification by third-party.
