Bristol Hospital sought to upgrade its aging infrastructure to improve comfort, increase efficiency of its operation, and combat high energy costs. With limited capital available, the hospital was challenged to initiate needed improvements, including replacement of its fifty-year-old air handlers. “Infrastructure upgrades had been postponed to address other priorities,” said Tom Roche, construction director, Bristol Hospital. “We had a lot of aging equipment; it was time to do something.”
Having worked with Bristol Hospital on a variety of turnkey projects, Trane was familiar with the organization and its challenges. Based on this experience, the hospital engaged the company as their strategic partner for a comprehensive upgrade project. Working together, the hospital and Trane began by identifying areas of critical need to uncover opportunities to improve operations, save energy, and maximize utility incentives.
Investigating financing options
Trane initiated conversations with a bank mortgage lender regarding the hospital’s financing needs. Bristol Hospital, Trane, and the lender evaluated the potential upgrade options to prioritized the measures that would best address infrastructure needs and enable the hospital to apply savings, resulting from the upgrades, to help pay for other needed improvements. The bank mortgage lender also proposed a unique financing option that would allow the hospital to move forward with the project, while adhering to its tight budget parameters. “Rather than providing a typical loan, the lender outlined an equipment lease agreement,” said Kurt Barwis, president and CEO, Bristol Hospital. “That gave us the option to lease the equipment for our immediate use and purchase it at a later date.”
Implementing upgrades without interruption
Frequent and effective communication with the hospital and subcontractors was key as Trane moved ahead with upgrades at the living, working hospital. Coordinating and scheduling, Trane carefully engineered and executed the demolition, installation, and change-over process to replace air handlers and roofops that served patient areas and critical operations of the hospital. Cognizant of the fact that the air handlers were located above the maternity ward, Trane replaced the five air handlers one at a time, alternating demolition of the old units with cross-over connections to the new equipment, ensuring no interruption to the 24/7 operation.
Improving air quality and efficiency
Trane selected Performance Climate Changer™ units to replace the hospital’s aging air handlers, located in a congested, fifh floor mechanical room. Trane® Horizon™ Dedicated Outdoor Air Systems were chosen to condition and dehumidify 100 percent outdoor air year-round. The updated, resized equipment is helping to increase efficiency and comfort, while reducing maintenance costs. In addition, with the new air handlers running at 50 percent speed of the old ones, noise levels for the maternity ward and throughout the hospital have been reduced. “With our old ine1cient equipment, there was a lack of humidity and temperature control,” said Roche. “Plus, the air handlers were so noisy that you couldn’t talk to anyone when you were near them.”
Reducing energy and water consumption
To further reduce energy consumption, lighting fixtures throughout the hospital and in parking lots were retrofitted with LEDs. Building envelope upgrades included reinsulating of the roof and windows, adding door sweeps, and installing steam traps and pipe insulation. In addition, Trane identified areas for improvement and worked with the hospital’s energy management system provider to expand and modernize their controls system.
Water efficiency was important to the hospital, as well as the City of Bristol, which at times experienced water supply issues. To reduce consumption, sterilizers were replaced with more water-efficient equipment and lowflow fixtures were installed. Trane’s exceptional communications again enabled a smooth transition, with installation of the fixtures occurring in occupied rooms of the busy hospital, while patients rested in their beds.
