GOC1354436-CS - Chilled Water Plant Optimization & Legionella Mitigiation

1.) Install Variable Frequency Drives (VFDs) on the compressors of two (2) remaining chillers (Chillers #2 & #3) 2.)
2.) Install VFDs on the three (3) primary chilled water pumps (P#8, P#9, & P#10).
3.) The sequence of operation for these chillers and primary chilled water pumps will be revised in the building automation system (BAS).
4.) Replace the existing three (3) primary and one (1) secondary chilled water pump motors with new inverter duty, high efficiency motors.
5.) Install six (6) new motorized isolation valves on the cooling tower equalization line, cooling tower return header and cooling tower supply header
6.) Perform any required modifications to the water treatment system to individually treat each tower separately.
7.) Perform controls modifications to enable cooling tower #1 to serve chiller #1's heat rejection requirements, cooling tower #2 to serve chiller #2, and cooling tower #3 to serve chiller #3.
8.) The existing drift eliminator shall also be investigated further and repaired or replaced if need be to ensure the potential for airborne contamination is reduced to minimum.
9.) Apply and oversee the application and measurement & verification (M&V) of applicable Hydro Ottawa (Local Distrubution Company, LDC) incentives.
10.) Update the Legionella Bacteria Control Management Program (LBCMP) for 350 King Edward Building following any modifications.
11.) Update water treatment regime for all new equipment.
