LSW conducted an initial feasibility study and schematic design for 1,400-ton chiller plant (CFC) and HVAC system. We surveyed the age and condition of the existing chillers, chilled water pumps, tower water pumps & cooling towers. We also interviewed operating staff and service contractor to determine adequacy of existing equipment, and reviewed utility bills and developed load profiles. In addition, we provided SPC documentation and follow-up monitoring to support the $116,000 incentive from the local utility.

This project also included replacing ceiling plenum, and a constant volume air supply system with a ducted, variable volume system in the Probation building. We were also responsible for conversion of controls for the Juvenile Hall, Probation Building, and Court Building to DDC. We provided new cooling plant to serve Probation & Court Buildings, and replaced rooftop air handlers with VAV/VFD air handlers at the Court Building. We also coordinated with the concurrent master planning for the complex, and installed lighting controls in both buildings.
