In fact, the hospital’s physical constraints presented a number of design challenges. Union Hospital, which sits within the confines of a city block, had limited area available for new construction. At the same time, the hospital needed the CHP system to be quiet for patients and out of sight for visitors. Unison decided to place the CHP system in front of the building, behind a custom-built wall that matched the hospital’s aesthetic. The system runs at only 65 db, allowing for normal conversation immediately outside the CHP’s walled enclosure. Despite the construction hurdles and custom engineering, Mark Mears, Facilities Management Director at the hospital, said, “The experience with the design team was outstanding, every step of the way.”
Looking ahead to the 20-year relationship, Mears said, “Unison was without a doubt the best company that we could have partnered with.” Operational in October 2019, Union Hospital’s CHP system now runs at over 65% efficiency, offering a projected $120,000 in first-year savings alone. And most critically, the system offers peace of mind for the patients, medical and facilities staff at Union Hospital. If the grid goes down, the CHP system will engage island mode and continue supplying heat and power, ensuring the building remains operational, comfortable, and safe for staff and patients.
