When Baptist Hospital’s chillers were not operating at optimal capacity. After loud and unstable conditions emerged, and a surge condition was detected, ThermaServe was called in to correct the chiller plant problems and increase energy efficiency for this critical care facility.
Baptist Hospital’s chillers were not operating at optimal capacity. After loud and unstable conditions emerged and a surge condition was detected, ThermaServe was called in to correct the chiller plant problems and increase energy efficiency for this critical care facility.
When both centrifugal chillers were operating, the 750-ton chiller return temperature was the same as the return secondary water temperature, but at the same time, the return water temperature to the 400-ton chiller was at a lower mixed water temperature. This condition caused the 400-ton chiller to operate at a much lower percentage of design load than the 750-ton chiller. The York 400-ton constant speed centrifugal chiller runs inefficiently at low loads. If this chiller was variable speed, it would operate very efficiently at low loads.
We relocated the 750-ton chiller chilled water return pipe connection from the secondary loop chilled water return to the primary loop chilled water return. We reconfigured the primary chilled water pumps to provide 2.4 gallons per minute per ton and replaced the solid-state starter for the 400-ton chiller with a variable speed drive. We supervised building automation personnel in reprogramming the chiller plant control system for optimal chiller staging and condenser water temperature control.
When Baptist Health converted a former retail space into a new outpatient care center, ThermaServe delivered a complete plumbing system renovation—including a specialized vacuum system installation—to meet healthcare standards, eliminate floor trenching, and ensure an on-time, disruption-free facility launch.
A large part of the mechanical scope was the need for a full plumbing renovation to meet the complex clinical needs of a healthcare environment, including water savings, infection control, and construction schedule constraints.
Adding complexity was the specification of an Acorn sanitary vacuum system, an advanced plumbing technology requiring specialized installation of nonconventional appliances and valves.
ThermaServe was contracted to provide and install the full commercial plumbing system, including:
Our team managed the installation of both conventional and specialized plumbing components with zero disruption to other trades or project deadlines. The vacuum plumbing system eliminated the need for floor trenching and cutting—saving time, reducing dust and debris, and improving infection control compliance during construction.
We also leveraged our healthcare experience to ensure the system was installed for long-term reliability and water conservation in a patient-focused environment.
This successful installation as per the design plans and specifications delivered long-term reliability, and enabled Pavillion Health Services and Baptist Health to open their new primary care facility on schedule.
ACI developed a comprehensive solution for Washington Hospital Center to bring their six boilers into compliance and set the stage for a greener future.
The Washington Hospital Center, a 900-bed hospital, serves as the flagship hospital for MedStar Health and is one of the largest medical centers in Washington, D.C. The facility is the referral center for patients with complex conditions, as well as a safety-net hospital. A central plant supports the entire medical center campus.
When Washington Hospital Center wanted to launch a transformative project to upgrade all six boilers in their central plant, they engaged ACI to tackle this daunting challenge. The existing equipment, dating back to 1955, was not only outdated but also failing to meet new emissions regulations. Given their age, the burners were not loading oxygen properly, resulting in emissions that were above the limits set by the D.C. government. ACI’s team of experts rose to the challenge and developed a comprehensive solution that not only brought the boilers into compliance with the latest regulations but also set the stage for a greener future.
Due to the hospital’s 24/7 operations and the need for boiler redundancy, a completeshutdown of the boilers during the improvement project was not a viable option. It was essential that a phased approach be implemented to eliminate disruptions to patient care and ensure that each boiler was fully commissioned before work on the next boiler began. ACI developed a plan to upgrade all six boilers at the client’s site while also maintaining redundancy, in accordance with hospital policy, to ensure that the upgraded boilers were commissioned before starting on the next upgrade.
ACI’s certified team split the project into two phases, upgrading the winter-use boilers in the summer and summer-use boilers in the winter, to eliminate any downtime and ensure that hospital operations could continue around the clock.
It was crucial for the hospital to find a partner who could manage the project in a manner that would ensure continuity of operations for the hospital and ultimately patient care. Because of ACI’s exceptional service and achievements in the first phase of this project, Washington Hospital has entrusted ACI with continuing the upgrading of their boilers. ACI’s phased off-season approach ensures minimum disruption to the hospital’s operations and ensures the facilities continue to run smoothly.
Under the BGE Smart Energy Savers Program®, GFS provided full retro-commissioning (RCx) services at three Johns Hopkins Medicine (JHU Medicine) facilities, resulting in BGE RCx rebates of $15,000 per facility as well as ongoing energy savings.
RCx services were performed throughout more than 245,000 sq. ft. of building space at Johns Hopkins Health Care and Surgery Center, Green Spring Station Pavilions I and II in Lutherville, Maryland, and at the Johns Hopkins Health Care and Surgery Center in White Marsh, Maryland.
GFS provided turn-key retro-commissioning services, including facility audits to identify deficiencies, a retro-commissioning plan, and project management.
