TLU’s Mechanical Systems Get a Little TLC
This reality makes it necessary that administrators consider alternative funding mechanisms when they’re evaluating facility investments.
The facility department at Texas Lutheran University (TLU), Seguin, TX, needed funding to replace an aging central plant and other infrastructure items. Not wanting to draw from the endowment fund, the department heads decided to explore performance contracting as a means to fund improvements.
“Our hvac equipment was too old to be efficient and was breaking down in increments of $100,000 nonbudgeted repairs. We needed to stabilize our expenditures for hvac,” says Alan VanBodegraven, vice president for business and finance.
“We did not have the expertise on campus to design a system, monitor subcontractors, and make the right equipment choices,” he continues. “Our system went down and we had very little time to get it up and running before the cooling season started. We did not have time to do an in-depth study. The performance contracting method made it feasible.”
Performance Contracting, Rebate Fund ProjectTLU eventually decided to fund its facility modernization project using the “Performance Agreement for Comfort from Trane” (PACT). The $3.1 million project is being funded using the resulting $577,000 in annual energy and operational savings. A one-time utility rebate of $238,000 also helped fund the improvements.
Trane met with the staff at TLU to better understand their current and future facility needs. Then the manufacturer’s staff analyzed TLU systems and proposed options for them to consider. The project was soon fully underway.
The primary goal of the project was to provide reliable comfort with little or no upfront capital. The specifics of reaching this goal addressed the antiquated central plant and operating inefficiencies.
New EquipmentThe central plant was reconfigured to include new boilers and chillers for more reliable operation at a lower cost.
Variable-flow pumping was designed into the system for further efficiency. A new cooling tower and switchgear were added to serve the new equipment.
In addition, modifications to the existing plant and the new roof were included to improve the functionality of the facility. “Building aesthetics were especially important to us,” comments Tom Dodgen, physical plant director.
New air-handling units were installed in the Schuech Fine Arts Center, Knutson Hall, and Hahn Hall, to help improve comfort and indoor air quality throughout the buildings.
Additional air distribution improvements were made at the Beck Administration Center. A dual-duct system was replaced with a vav system to optimize comfort and energy conservation.
On the controls side, control valves were replaced throughout the campus to optimize energy conservation, and a Tracer Summit® building management system was installed to improve consistency and efficiency in facilities operation.
“Our staff is able to respond to complaints and emergencies much quicker than in the past,” says Dodgen.
Extensive construction and project management tools were necessary due to the complexity of the project. Schedules were developed to speed along the installation with careful consideration to classroom occupancy.
To ensure that the results are as anticipated, PACT is administered through a performance management program. Service, monitoring, and training are provided to maintain the installed systems operating efficiencies. The risk management aspect of the program ensures TLU long-term project performance.
