Energy Management System (EMS): Full U.S. Guide to Functions
A complete U.S. guide to Energy Management Systems (EMS). Learn how EMS reduces costs, improves reliability, and optimizes energy use for modern U.S. facilities.
1. Industrial Manufacturing: A leading automobile manufacturer implemented an EMS that optimized its energy consumption across multiple facilities. The system used real-time monitoring to adjust energy usage dynamically, leading to a 20% reduction in energy costs within the first year.
Averaged energy savings of EMS for artificial lighting system is 39.5%. The highest saving ratio of EMS for lighting system is 86%, marked by #6 in Fig. 5. The highest energy savings is achieved by the daylight assisted energy management and de-lamping function, as indicated in Table 11 (the specific function).
Among the huge number of publications, a part of papers are picked up for studying energy savings by EMS. Selecting criterions include: Selected papers report quantitative energy saving data obtained from real case studies. Research works provides detailed descriptions of energy management sites or technical specifications of managed equipment.
According to Eq. (2), the null hypothesis could not be rejected, and the yearly energy saving tendency is not clear. Therefore, the analysis of energy savings for these three facilities would be focused on the averaged value. Averaged energy savings of EMS for artificial lighting system is 39.5%.
