UCF Business Administration Building HVAC controls retrofit

Project Summary

Hanson provided professional engineering services for the assessment, design and construction phases of the University of Central Florida’s Business Administration I (Building 45) controls retrofit project.

For the assessment phase, Hanson conducted an ASHRAE Level II energy audit by reviewing historical utility data, conducting a facility site survey, performing a space function analysis, identifying facility improvement measures (FIM), reviewing current operations and maintenance procedures and tactically retro-commissioning the functionality and capabilities of the HVAC systems via the building automation system (BAS). The BAS infrastructure was also evaluated for upgrade and replacement options.

The design phase involved replacing the BAS gateway, communication wire and field controllers; replacing field devices, sensors, device wiring and pneumatic actuators; new sequences of operations for optimization; and upgrading the building chilled water pump layout to the current UCF standard by adding an additional chilled water pump, bypass piping and required valves.

With the completion of this project, UCF has gained N+1 redundancy at the chilled-water points of connection to the campus loop with a new, second chilled-water pump. The design also added controls to all the heating, air-conditioning and ventilation zones, which had been controlled via pneumatics; this gives UCF telemetry on how the building is performing.

Hanson also provided construction administration, which encompassed mechanical and electrical services.
