Abstract
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.
