With the addition of fault-detection diagnostic software to its energy savings efforts, South Carolina-based Prisma Health has gone from having zero ENERGY STAR hospitals in its system to now having two. In that same time, according to an article on the Health Facilities Management website.
Patewood Memorial Hospital deployed the software across its entire building management system but the real pay off came from its air-handling units and chilled water system.
Some of the biggest energy wasters were leaky water valves and faulty valve actuators and damper actuators. After correcting these issues, Patewood saw more than $1 million in energy savings.
Prisma expanded the initiative to more facilities. To date, the system has saved nearly $2.5 million.
Hospitals are second only to food service buildings for energy use per square foot in the commercial sector, according to the U.S. Energy Information Administration.
