Facilities pursue Superior Energy Performance® (SEP®) certification to validate robust use of the ISO 50001 standard and the significant, ongoing savings it enables. Detailed accounts by facilities that have certified their ISO 50001 achievements to SEP make a clear business case for rigorous use of an ISO 50001 energy management system (EnMS).
Gain an insider’s view on the associated challenges, strategies, energy savings, and other benefits. Learn about the potential cost savings of implementing ISO 50001 and SEP across multiple sites, using the enterprise-wide approach. Read the cost-benefit analysis, review the single-site, enterprise-wide, and measurement and verification (M&V) case studies, and view engaging videos and presentations.
ISO 50001 energy management systems produce energy savings that directly impact the bottom line and endure over time. One analysis examined ten facilities that significantly improved their energy performance using ISO 50001 and achieved SEP verification of those results. Find all the SEP-verified data in the SEP Cost-Benefit Analysis, which documents deeper, more sustained energy savings with ISO 50001:
- 12% reduction in energy costs within 15 months of starting implementation, on average
- Annual savings of $36,000 to $938,000 using no-cost or low-cost operational measures
- Paybacks of less than 1.5 years in facilities with energy costs above $2 million annually (less than 2.5 years for those with energy costs of $1 million per year)
Beyond impressive energy and cost savings, facilities note that, in combination, an ISO 50001 energy management system (EnMS) and verified energy performance improvements deliver further benefits:
- Provide data and analysis to inform decision making
- Take EnMS to a new level—using advanced, rigorous tools to track data and assess impacts
- Raise the visibility of successful facilities within the company
- Provide proof of performance—certification increases credibility internally and externally
- Attract national recognition to your program, helping it grow and succeed.
Facilities, large and small, describe implementing an EnMS, share internal and external costs, present energy and cost savings, and offer lessons learned in the following case studies:
This Detroit Diesel facility improved its energy performance by nearly 33% over 10 years and earned Platinum certification from the U.S. Department of Energy’s (DOE’s) Superior Energy Performance® (SEPTM) program. (February 2017)
MedImmune, the global biologics research and development arm of AstraZeneca, improved the energy performance of its Gaithersburg, Maryland facility by 8.5% by participating in the U.S. DOE’s SEP program. (July 2016)
CCP Composites US LLC incorporated SEP into its integrated health, safety, quality, and environmental management system to achieve a 14.9% improvement in energy performance over a two-year period. (June 2011)
Freescale Semiconductor Inc. engaged employees at all levels of the organization and leveraged facility-level activities into a corporate energy management program—improving its energy performance by 6.5%. (June 2011)
CASE STUDIES: ENTERPRISE-WIDE
A growing number of companies find they can leverage resources and cut costs by sharing a common ISO 50001 EnMS across multiple sites. The following case studies relate their strategies for achieving diverse benefits using this approach to SEP certification. Learn more about SEP enterprise-wide approach.
3M used the enterprise-wide approach to certify six sites to ISO 50001 and SEP, saving $3.6 million in energy costs. The approach cut per-site EnMS implementation costs by $23,600 and condensed the SEP certification timeline by six months. 3M plans to certify more sites around the globe. (May 2017)
Cummins concurrently certified three more U.S. sites to ISO 50001 and SEP—and reduced per-site implementation costs by close to $13,000. In the process, the company saved $4.1 million in energy costs and now aims to get 40 sites certified to ISO 50001 by 2020. (May 2017)
Nissan simultaneously certified three sites to ISO 50001 and SEP (including one recertification), saving close to 1,600 billion Btu as a result. With extensive energy metering already in place, the company spent only 0.4 FTE-year in labor to implement the ISO 50001 EnMS at each site. (May 2017)
Schneider Electric used the enterprise-wide approach to certify 19 sites (including 4 recertifications) to ISO 50001 and SEP. Using its Energy and Sustainability Services group to handle core EnMS tasks, the company cut its implementation labor by three-quarters and cut the timeline by half. (May 2017)
Accurately measuring energy performance allows organizations to predict and plan for energy usage, assess results of energy efficiency activities, and make informed energy-based decisions. These sites share their solutions to M&V challenges to help others.
Cummins’ Rocky Mount Engine Plant (RMEP) faced a modeling challenge where common production throughput and weather variables could not be used to predict the diesel energy consumption. (September 2017)
The HARBEC, Inc. plant in New York uses a mix of energy sources, including a combined heat and power (CHP) plant and onsite wind energy in addition to purchased electricity and natural gas, which made it impossible to model each individual energy source under the traditional approach. (September 2017)
