• Improved Patient Comfort
• Greater Energy Efficiency
• Reduced HVAC Installation and Operating Costs
Intended as a plan and spec project, when initial cost estimates came in significantly over budget, Cleveland Clinic
Florida moved to a design/build approach and established a team to reduce both design and construction costs without
sacrificing building quality or functionality. Open communications between team members was emphasized.
HKS Architects, a national firm headquartered in Dallas, Texas, designed the facility, using their extensive experience
in health care facilities. The construction manager was Centex Rogers, headquartered in Nashville.
Southeast Mechanical Contractors, Hollywood, Florida, was made a team member due to their reputation for designing highly efficient building mechanical systems. To reduce costs the physical
plant was built as a grade-level wing attached to the hospital using a "top-down" process. As each floor was finished it was sealed off and work moved to the next level. This eliminated materials and
workers moving through finished spaces, reducing cleanup and material handling. Southeast Mechanical’s Bill Catron said, "The top down approach works well, but doing plumbing work
top-down is a challenge. In some cases we needed to work on finished floors."
The HVAC plan centered on a chilled-water/hot-water system with high-efficiency chillers, central
station air handlers and constant volume air distribution with full reheat capability. Catron says chilled water systems are most efficient for managing indoor humidity and meeting year-round cooling
needs. "It was always planned as a chilled water project, but we had to find ways to reduce cost
without sacrificing capacity and control." Southeast Mechanical recommended a high-efficiency chiller plant with low-temperature chilled water and supply air. This reduced piping, valves, ducting
and air handler costs as these components could be downsized. The plan first called for two 950-ton chillers, but Southeast Mechanical recommended installing three 600-ton chillers instead. Catron
said, "This gives much more flexibility and the chillers can be optimized for best efficiency for more hours of the year. There also the added reliability of a third chiller."
Bill Bower, vice president of Southeast Mechanical Contractors, says that one way to dramatically reduce costs without sacrificing efficiency and reliability was the low temperature chilled water
design. Another solution was the Tracer Summit building automation system to optimize chiller and cooling tower operation for best efficiency and manage the ventilation, tempering and distribution,
and many other building functions including boilers and emergency smoke exhaust. The Tracer Summit system also communicates with the fire alarm system. Additional cost
savings were realized by placing cooling towers on the roof, minimizing piping and reducing
Construction was finished on time and steps taken to reduce initial costs were successful. The
Tracer Summit™ system provides additional cost savings since all Trane equipment uses
factory-installed controls designed to work with the control system, eliminating control
interfaces. Southeast Mechanical’s Joey Manteiga says, "The open protocol aspect of this
system allows the owner flexibility in installing other systems in the future."
Southeast Mechanical worked with South Florida Trane to install the control system. David
Fernandez, South Florida Trane sales engineer, points out the importance of Southeast
Mechanical experience in building comfort systems and finding ways to reduce construction and
operating costs and the value of the Tracer Summit system relative to service capabilities. Trane
is currently providing HVAC maintenance services at Cleveland Clinic Florida. Fernandez says,
"The system provides information that allows us to perform timely preventive maintenance rather
than repairing failed equipment. It’s hard to over-emphasize the value of the Tracer Summit
system status reports." The hospital facilities group has learned to use the Tracer Summit
system to maximize facility efficiency and are pleased with the building control system
performance, demonstrating the efficiency possible using new HVAC systems designs and
control systems, intelligently applied, to meet customer needs.
Cleveland Clinic Florida is a
