INDIAN RIVER COUNTY PHASE 2 TECHNICAL ENERGY AUDIT RECOMMENDED ENERGY CONSERVATION MEASURES found to be applicable and advantageous for the facility. The identified high water consumption faucets, water closets, and urinals should be replaced at this facility. The field investigation identified 104 restroom fixtures at the facility. After completion of the analysis,55 replacement fixtures were proposed in the water conservation project shown below: Health Department Proposed Water Conservation Fixtures 4"Single Metered Faucet Dual Temp 0.5 GPM 2 8"Dual Lever Faucet Gooseneck 0.5 GPM 24 8"Sin le Lever Lounge Faucet with 0.5 gpm aerator 0.5 GPM 2 Floor Mount Dual Flush Water Closet-Tank 1.6/0.8 1.0 GPF 9 Floor Mount Dual Flush Water Closet ADA-Tank 1.6/0.8 1.0 GPF 7 Floor Mount To Sud Floor Outlet Water Closet-FV 1.28 GPF 2 Floor Mount Top Sud Floor outlet Water Closet ADA-FV 1.28 GPF 6 Wali Hung Top Sud Urinal—FV 0.125 GPF 3 Exclusions contain the following: • Existing low consumption faucets or faucets used for medical purposes • Existing low consumption showerheads Health Department water conservation has savings at$1,645, with a cost of$56,570, and a payback of greater than 34 Yrs. Therefore, FPLES does not recommends that Indian River County moves forward to implement the water conservation retrofit. The detailed analyses and cut sheets for this ECM can be found in Appendix 7& K. ECM — 4: HVAC FPLES evaluated the potential savings of replacing the existing 96-ton air cooled chiller at the Health Department with a new high efficiency 96-ton air cooled chiller with variable flow primary pumping. • New 96 ton air cooled chiller, 1.15 l ton • New 10 HP, high of l Dee riabie speed pump with drive. New Variable Speed Drive to be located in AH • I room adjacent to Chiller yard. • New pot feeder, r snd expansion tank. • New chiller con bl paller and variable pump control.
