INDIAN RIVER COUNTY PHASE 2 <br /> TECHNICAL ENERGY AUDIT <br /> RECOMMENDED ENERGY CONSERVATION MEASURES <br /> found to be applicable and advantageous for the facility. The identified high water consumption <br /> faucets, water closets, urinals and showers should be replaced at this facility. The field investigation <br /> identified 582 restroom fixtures at the facility. After completion of the analysis, 73 replacement <br /> fixtures were proposed in the water conservation project shown below: <br /> Proposed Water Conservation Fixtures <br /> 74"Sin le�Mite�ed Faucet�Daem 0.5 GPM 28 <br /> 4"Sin le Faucet em 0.5 GPM 5 <br /> 8"Dual eaucet Gooseneck0.5 GPM 3 <br /> 8"Sin le Lever Lounge Faucet with 0.5 qpm aerator 0.5 GPM 1 <br /> Floor Mount Top Sud Floor Outlet Water Closet-FV 1.28 GPF 17 <br /> Floor Mount Too Sud Floor outlet Water Closet ADA-FV 1.28 GPF 18 <br /> Wall Hun To Sud Urinal—FV 0.125 GPF 1 <br /> Exclusions contain the following: <br /> • Existing low consumption faucets. <br /> • Existing low consumption water closets. <br /> Existing low consumption showers. <br /> The annual savings of $3,684 could not support the cost $84,291 and provded a simple paback of <br /> greater than 20 years. FPLES does not recommend that Indian River County moves forward to <br /> implement the water conservation retrofit. The detailed analyses and cut sheets for this ECM can <br /> be found in Appendix X K. <br /> ECM —4: HVAC (none at this site) <br /> ECM - 5: Solar Hot Water System <br /> Solar hot water systems are a proven way to provide hot water needs using the sun's free energy. <br /> As a result, FPLES performed an analysis to supplement the existing boiler C with a ground-mount <br /> solar hot water system. The system includes 35 panels, a small AC powered circulating pump, <br /> control valves, copper piping, strorage tanks (two) and freeze protection. <br /> For this application and location, based on the water usage, as determined by the site <br /> measurements, the savings were calculated as 5,046 therms and $4,547 per year. When compared <br /> to the implementation cost $319,814, the simple pay back exceeds 50 years. <br /> t <br /> PrOP140talY and Confidential 91 FPL Energy Services, Inc. <br />
