The U.S. Energy Information Administration reports that while large hospitals account for less than 2 percent of all commercial floor space, they consume 5.5 percent of the total delivered energy used by the commercial sector. In addition, with healthcare costs on the rise, targeting energy use for cost reductions makes sense because it is one budget item that can be directly controlled by a healthcare facility.
The objective of this CARD grant, awarded to CLASS 5 Energy of Vadnais Heights, Minn., was to pilot a comprehensive behavioral and operational energy efficiency program for the healthcare market, with a goal of creating a program that could reduce energy use and costs without a significant financial investment and without affecting patient care. The partner for the pilot program was Ridgeview Medical Center (RMC), which was selected based on its previous sustainability efforts, enthusiasm toward the behavior component of the program, and diverse building mix (including a hospital, five clinics, four professional buildings, a hospice, a HomeCare/HME site, and a staff office building).
The pilot period was from June 2011 through December 2012. During the pilot period, there were no asset projects implemented and RMC’s only investment was its leadership’s time to oversee and implement the program.
The main behavioral strategies included:
With 15 months of data, results indicate that a healthcare-focused behavior energy program can be successfully implemented. RMC saved more than $75,000 and reduced overall energy use by 6 percent (see Figure 1). As the figure indicates, savings tended to be minimal or negative in the first few quarters of the pilot, which is expected as staff learns about the program and implementation is in transition, and then ramped up in later quarters.

Savings varied by facility, with some of the off-site RMC clinics obtaining savings that were significantly higher than the overall average (see Figure 2). One reason for this difference was that the clinics are not required to operate 24/7, but another reason was one or two employees at high-saving clinics who were particularly committed to the energy saving effort and were able to provide a higher level of enthusiasm and motivation for other employees, highlighting just how much difference an on-site champion can potentially make.

Results of a survey conducted in the last quarter of the pilot indicate that the vast majority of employees were fully engaged and that the pilot program has changed their behaviors, with 85 percent reporting they are more likely to engage in energy saving behavior and 91 percent stating they learned that individuals can have an impact on organizational energy costs.
The pilot concluded that any organization interested in achieving similar energy and monetary savings without a significant capital investment can do so, provided three key components are in place:
