Forrester Research recently reported that something like 45 percent of businesses are investing in some sort of enterprise software for managing energy consumption. A case study that shows how Bentley University has been using one such application, Infor EAM Asset Sustainability, gives you a sense of why this is so–and why this sort of thing isn’t just for big companies.
The university originally looked to the Infor software as a means of automating maintenance workflow across its 46 facilities. More recently, it began wondering how to apply this same automation to managing its electricity consumption. Specifically, by integrating the software with building control systems to get a better sense of what was operating properly, and what metrics should be questioned. The software also helps with preventive maintenance.
When I spoke with the Bentley University energy systems engineer, Jessa Marshall, about the project, she says the overall mission is to manage each building system (or “asset”) so that it is running at its most optimal levels. By managing these technologies to certain guidelines — recognizing that each day brings new operating variables in the form of weather changes and building occupancy — the university can keep things running more smoothly, she says.
“We understand how a piece of equipment should be running vs. how it IS running,” Marshall says.
So, for example, the university staff was able to see that one of its chillers was working at a dramatically different rate than the others. It was consuming 20 percent more electricity. So, the engineers adjusted the settings and made a different chiller the lead system for that building, using the more energy-hungry one as a backup, Marshall says.
In the first 11 months of using the software, Marshall says the university has reduced electricity consumption campus-wide by almost 10 percent. That’s more than 2 million kilowatt hours, or the equivalent of turning off all the electricity on the campus for about 30 days.
Marshall says, where necessary, the university is using basic energy meters from Schneider Electric to feed the data into the Infor software. Some of the building systems can interact with the software directly.

Rod Elsworth, vice president of global asset sustainability for Infor, says the sustainability edition of its enterprise asset management application can be licensed according to the number of concurrent users or according to the number of meters that are feeding information.
