EL DORADO, Kan. — The Susan B. Allen Memorial Hospital recently began a $3 million energy savings retrofit project, with Schneider Electric serving as general contractor and lead designer. The project is currently in the construction phase, with completion scheduled for April of 2013. The hospital’s main building, medical plaza and dialysis center will all get some upgrades, such as replacing an aging steam power plant with a new water system employing boilers, in addition to several changes involving electrical and lighting functions. Schneider will also make a few changes to increase the comfort levels of patient rooms and physician offices. The hospital will still use a smaller steam system for some very specific functions like the sterilization of medical tools and instruments. Schneider’s work is guaranteed to provide the hospital with a 31 percent energy cost savings per year over the 15-year life of the contract and eliminate the equivalent of 567 cars per year in terms of cutting carbon emissions.

Jordan Lerner, regional director of sales and engineering for Schneider Electric, explained that several changes, such as lighting retrofits, occupancy sensors that control when lights are on, and automation systems that optimize power use, all serve the dual purpose of expending less energy and extending the life of equipment the hospital depends on. Lerner compared automatically turning equipment off when not in use to having fewer years on a car’s odometer; the product will simply last longer if it isn’t running when no one is using it. He added that the automation system would not only regulate electrical use to match the facility’s daily and weekly schedules, but would also make seasonal adjustments throughout the year to adjust for the effects of the outdoor environment on the controlled climate inside the building.

Lerner said one of the more unique features was an ultraviolet light system that eliminates many possible biological contaminants that the ventilation system might pull in from the outside air. He explained this was a feature rarely seen outside of the medical world.

Lerner commented that his company went into each project with the most open-minded approach possible. He said Schneider often used products and services that his company used in the past and trusted, but was willing to try something new depending on the client’s needs and wishes. He said the staff at the memorial hospital brought an equal degree of open-mindedness, which benefited the project greatly. Lerner explained the hospital staff wanted to go for efficiency upgrades with the fastest return on cost-savings possible, but signed up for a long-term approach when they learned how much more cash would be preserved with that approach. He felt that many hospitals focused less on green features than other industries because they often faced financial decisions between structural upgrades and medical equipment, but this facility seemed to buck that trend and embraced the long-term view on cost savings.

Lerner felt that one of the least recognized functions of a retrofit company like his was to serve as a mediator between various interests at a hospital, bridging the gap between the boardroom and the boiler room. He said this part of the operation went particularly smoothly in this case, as all sides seemed interested in working together to find the best solution.

Jim Poffinbarger, director of the hospital’s environmental services department, said the feeling was mutual. “Based on our time working together, we feel that Schneider Electric is best equipped to assist us in reducing our energy use and creating a more sustainable hospital that better serves our patients and staff while demonstrating our commitment to energy efficiency and environmental responsibility.”

Keeping patients, families and staff cool for less

At Hackensack University Medical Center, patient care comes first but operational efficiency and environmental impact are also among its priorities. In the Central Plant Operations alone, the medical center has achieved savings of more than $700,000 through smart management, including more than $400,000 through continuous energy oversight of the chiller plant.

HackensackUMC, a nonprofit teaching and research hospital located in Bergen County, N.J., is the largest provider of inpatient and outpatient services in the state. This 775-bed medical center offers comprehensive care at its facilities, including the Heart & Vascular Hospital, the John Theurer Cancer Center, the Joseph M. Sanzari Children’s Hospital and the Donna A. Sanzari Women’s Hospital.

Over the years, HackensackUMC’s initiatives to improve patient care have earned many honors, including The Joint Commission 17 Gold Seals of Approval; it was named one of HealthGrades America’s 50 Best Hospitals for six years in a row (2007-2012); and it was cited as one of U.S. News & World Report’s 2011-12 Best Hospitals (National) for Cancer, Cardiology & Heart Surgery and Geriatrics. U.S. News & World Report also named The Joseph M. Sanzari Children’s Hospital at HackensackUMC to its Best Children’s Hospital List in Neurology and Neurosurgery.

HackensackUMC has taken steps to continually improve operational efficiency and reduce environmental impact. In February, the medical center signed a memorandum of understanding with the U.S. Environmental Protection Agency (EPA) to reduce energy consumption by at least 10 percent and become an EPA Energy Star partner, reduce the use of plastics, reduce and recycle solid waste, complete a 7,000-square-foot “green roof” to reduce stormwater run-off, reduce air pollution from its vehicles, and use nontoxic cleaning products.

Lowering Energy Consumption
As part of the hospital’s efforts to reduce energy consumption at least 10 percent, plant operations is improving energy efficiency in its district cooling system and central boiler plant.

The central district cooling system is made up of four central chilled water plants, which provide 8,000 tons of cooling to multiple critical facilities. The multifuel central utility plant consists of Carrier electric centrifugal chillers and a 1,600-ton York steam turbine. The 3,000-hp central boiler plant generates a maximum of approximately 51,000 pounds per hour of steam for the medical center’s facilities.

With other efficiencies planned for the future, including upgrades to the boiler plant with new equipment and optimization of its operations, and considerations about ceiling systems for heating and cooling, such as the ones available at therma.cool, the plant operations department still wanted to look into additional steps to reduce the medical center’s $2.2 million chiller plant operating costs.

The Solution: Continuous Energy Oversight
With the goal of reducing the cost of operating the multi-fuel central chilled water plant, the medical center’s engineer and plant operations supervisor looked for an opportunity to work with an energy advisory firm with expertise in analyzing utility rates and experience operating energy plant and metering systems. The answer was utiliVisor Energy Plant Services, which provides oversight of energy systems for health care and other mission-critical facilities. The company implemented a “real-time” web-based metering and monitoring system in the plant and used it to oversee, analyze and report on the facility’s HVAC systems and utility management with automatic utility invoice processing.

The engineering team reviewed HackensackUMC’s chiller plant operation to identify inefficiencies and projected that the medical center would save $400,000 per year by improving chiller part-load performance, correcting condenser water and chilled water flows, monitoring and optimizing the hydraulic bypass, tuning the control loop, and improving chiller sequencing. The proposal included managing a team from Siemens Building Technologies to upgrade the medical center’s existing building control system with additional chiller performance data from the Carrier and York chillers; and install ultrasonic flowmeters to the chilled water, condenser water, steam condensate and the main chilled water bypass valve.

The utiliVisor team also was responsible for:
Monitoring chiller plant operations 24/7/365
Recommending operational adjustments to reduce energy costs
Providing energy use data in “real time”
Tracking actual chiller performance vs. design performance
Enhancing control system performance
Training the medical center’s engineering staff
Analyzing electric vs. gas utility rates to determine which system is most cost effective to operate at any point in time
Customizing the data analysis for the medical center’s reporting structure

HackensackUMC’s investment totaled $434,093 for hardware, software and the first year of monitoring. Before the medical center made a decision, the plant operations supervisor visited chiller plant operations at another major medical center in the New York-New Jersey metropolitan area with a similar chiller plant to talk with them about their experience and was impressed with their results.

Top Success Factor: Teamwork and Communication
HackensackUMC went ahead with the program. In addition to over $400,000 in savings per year, the relationship with the energy oversight provider has exceeded expectations. Based on continuous monitoring of the medical center’s chiller plant operations, their engineering team emails or calls the medical center’s operators and supervisor to recommend operational adjustments to reduce energy costs. For example, an analysis was performed recently that determined a better sequencing of chillers to match the outside air conditions and meet the hospitals required load. This step alone is saving HackensackUMC approximately $3,000 per day of operating costs.
That is just one example out of many. The operating data tracking actual chiller performance is also used to compare design performance to demand operating improvements from our equipment-servicing vendors.

The health care industry is under increasing pressure to find ways to improve patient care while managing costs, and HackensackUMC is no exception. So keeping patients, families and staff cool for less makes good economic sense.

John Nesbitt is the Infrastructure Supervisor of Plant Operations for Hackensack University Medical Center, Hackensack, N.J.
