3M, Schneider Electric Score Big Efficiency Gains Via ISO 50001 and the SEP
Industrial facility energy managers with efficiency programs in place generally feel pretty good about themselves. After all, they are proactively addressing the issue and doing what needs to be done.
They may not be doing all that can be done, however. During the past few years, the 3M Company and Schneider Electric have used two related initiatives – the International Organization for Standardization’s ISO 50001 and the U.S. Department of Energy’s (DoE) Superior Energy Performance program – to save significant amounts of money. The results have been gains in efficiency in the 60 percent range, even when the plants already had energy management programs in place.
The key, according to Paul Scheihing, a Technology Manager for the DoE’s Advanced Technology Office, is structure. “We usually view energy management as a cost of doing business,” he told Energy Manager Today. “The way it’s managed is more on a project basis… What ISO 50001 does is structure how energy is managed in an organization, which implies many different people involved across the organization and the integration of energy management into the overall business strategy.”
ISO 50001, which was introduced in 2011, is used by about 15,000 facilities worldwide. The DoE, Scheihing said, introduced the Superior Energy Performance (SEP) to verify energy efficiency gains made by ISO 50001, which makes it easier for advocates to gain corporate buy-in. “The energy savings and cost saving are more believable to people giving [authorizing],” Scheihing. “It adds credibility to the ROI.”
ISO 50001 is about creating a structure that everyone in the organization. This includes technology managers and those who deal with procurement, communications, operations, maintenance, facilities and other tasks. It also reaches up to top management. “It’s about getting these people to talk to each other and a more common approach to managing energy,” Scheihing said.
ISO 50001 starts with quantifying energy coming into the facility, delineating its major uses and creating key energy performance indicators. The idea is to focus narrowly on what needs to be done to increase efficiency and cut costs. “What are the key things we are going to track our progress on?” Scheihing said. “It’s a classic case of ‘what you measure is what you manage.’”
Parallel requirements focus on communicating the message to all stakeholders, appropriately training staff and conducting internal audits. The goal is to assess results, gauge how the program is working and determine what the organization can do to improve.
The DoE believes that it has a good story to tell. The results, according to data collected by the Schneider Electric and 3M, illustrate the comparative savings during the past several years of facilities using ISO 50001 and the SEP and those that didn’t. From 2011 to 2015, Schneider Electric claims that its energy efficiency gains rose 11.5 percent in plants that didn’t use either structure. Savings rose 19 percent at 20 plants that did.
3M saw its energy savings rise 6.5 percent in plants without ISO 50001 and the SEP – and 10.5 percent across the 18 plants that implemented the approaches. The program now is active at five additional plants.
The level of savings of certified versus non-certified facilities was more than 60 percent for both companies. The average savings for the two companies over a three year period was 12 percent. An even more compelling element is that three-quarters of the savings were from “no cost/low cost” operational actions, Scheihing said.
The DoE is trying to expand use of ISO 50001 and the SEP into the commercial sector and is working with Hilton and Marriott chains in an effort to create a beachhead in the hospitality industry. A move into the federal sector also is on the radar. Such expansions likely will be in steps. ISO 50001 initially would be implemented alone. The SEP, with its focus on quantification of financial gains, would be added later.
