摘要

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。國際標準組織(ISO)於2011年6月15日公告ISO 50001 能源管理系統標準，企業亦將面對如何能有效提升能源使用效率、建立能源績效指標等課題。
由於全球電腦資訊科技技術進步快速，帶動電子零組件與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。本研究採用專家評估法探討某電子零組件與網路通訊產品公司案例，結合專家評估意見與實務整合能源實務流程之導入，提升ISO 50001能源管理系統之能源使用效率並進行ISO 50001能源管理系統國際認證。根據本研究案例某電子零組件公司之結果，應用本流程發展出多項節能實務解決方案，建立整合能源實務流程導入ISO 50001能源管理系統，提供空調、照明和綠能等等能源解決方案與智慧資料庫，成功提升該公司於2011年度能源績效指標之整體能源密集度，相較於基準年(2010)，2011年上半年導入期間階段與下半年執行實施階段分別下降18.5%與21.5% 並通過第三方公正單位之ISO 50001能源管理系統國際認證。
另研究案例某網路通訊公司之結果，採用專家評估法推展並有效提升ISO 50001 能源管理系統之能源績效指標，相較於基準年(2010)能源使用效率提升,年度能源密集度平均下降21.5%。導入ISO 50001能源管理系統對能源績效指標之能源密集度下降率，追蹤2011年下半年執行實施階段(20.21%)高於上半年導入期間階段(19.95%)，實施執行ISO 50001能源管理系統持續改善提升效益所致。對於採用能源服務產業ESCO履約保證有效完成ISO 50001能源管理系統與驗證，有利企業或組織成功完成節能目標並建置ISO 50001能源管理系統標準化並降低無法達成目標之風險，但對於合理計算節能效益結果反饋支付ESCO費用與投資改善設備之資金借貸融資仍需更多探討。由於ISO 50001能源管理系統之條文與要求架構於ISO 9001品質管理系統，隨著ISO 9001品質管理系統即將於2015年進行大幅度改版，ISO 50001可能將受到相關影響與變動，特別是績效管理與風險管理及相關評估影響更大。未來對其他不同產品或高能耗企業值得更多相關性研究。

Global energy sources are gradually becoming scarce and prices are continually rising. Governments and businesses in various countries are actively developing technologies for energy management and developing new sources of energy. On 15 June 2011, the International Organization for Standardization (ISO) announced the ISO 50001 standard for energy management systems. Organizations and enterprises are confronted with challenges associated with enhancing energy performance indicators, continuing to improve energy consumption efficiency, and managing third-party international certifications.
The rapid development of and computer information technologies has spurred high demand for electrical components and networking products, thereby substantially increasing energy consumption involving the production of their products. This research conducted the modified experts assessment method on the case studies of the electrical components and networking-product manufacturing companies, which develops an integration-energy-practice (IEP) process to improve energy efficiency in ISO 50001 energy management system and underwent ISO 50001 certification. According to the study results, the IEP process provides the energy-saving total solutions to improve 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 18.8% and 21.5% compared with the base year respectively. Using the IEP process to implement ISO 50001 energy management systems effectively facilitates electrical components and networking enterprises in improving energy efficiency, identifying energy-saving total solutions, and obtaining ISO 50001 energy management system international certification by third-party.
This study conducted cases studies of businesses that have introduced an ISO 50001 energy management system by using an integration-energy-practice model to improve energy performance indicators and to complete the international auditing and certification procedures for ISO 50001 energy management systems. The integration-energy-practice process efficiently provides enterprises with methods for developing sustainable energy management. Regarding the networking-product company study amount of reduction in energy intensity attributable to ISO 50001 energy management system implementation, the energy performance during the execution period of ISO 50001 (20.21%) was slightly superior to that of the period of implementation ISO 50001 (19.95%). This might be because the ISO 50001 energy management system continued to improve and provide benefits. Future studies are necessary to conduct long-term tracking of this trend. This result indicates that implementing the ESCO process effectively assists businesses in enhancing energy technology and improving energy efficiency. It integrates internal and external technical resources to establish energy technology think tanks, for promoting successful technology and experiences to various sectors, thereby allowing enterprises to integrate energy management, increase energy efficiency, and meet the ISO 50001 international standard for energy management systems.
