While the CHP system provides critical resiliency, it also allows PRMC to manage its operating costs by offsetting 81% of its annual energy consumption. In fact, Unison Energy ensured the hospital could benefit from efficiency savings by installing a custom thermal solution that connected the CHP system to the boilers on the other side of the campus.
Unison Energy installed over 4,000 linear feet of pre-insulated hot water piping with leak detection, routing the pipes underground, over a portion of the hospital roof, and along the walls. Where the pipes were visible, Unison Energy installed a decorative cover that matched the existing architecture. They also installed heat exchangers, pumps, and valves, and incorporated digital controls into the existing building management system in order to optimize heat delivery.
The resulting system provides hot water for the facility and allows the hospital to minimize its boiler usage. In the first two years since implementation, Unison Energy has already saved the hospital some $500,000 in energy costs.
What’s more, by choosing a Unison Energy solution, the hospital was able to step into a new role as an environmental leader. Thanks to its improved energy efficiency, PRMC has reduced its carbon emissions by 50% annually. Dr. Naleppa, PRMC’s president at the time, said, “By installing the CHP, we achieve both environmental and economic stewardship that is a benefit to our community.”
For Peninsula Regional Medical Center, a Unison Energy CHP system is an investment in the future. But it has already proven to be a success — in fact, it won a 2019 Energy Project of the Year Award from the Association of Energy Engineers (AEE), demonstrating the value it has brought to PRMC and the patients it serves.
