INDIAN RIVER COUNTY PHASE 2 <br /> TECHNICAL ENERGY AUDIT <br /> RECOMMENDED ENERGY CONSERVATION MEASURES <br /> FPLES performed a walkdown of the facility's domestic water system with respect to <br /> installing low flow and ultra low flow fixtures. As a result, it was determined that savings <br /> can be achieved through the replacement and/or retrofit of water fixtures. The analysis included <br /> determining the consumption of the existing (pre) fixtures, comparing it to the baseline water bill (see <br /> Modeling Methods, Section 3) and determining the consumption of the retrofit (post) fixtures <br /> water/sewer rates. . Once <br /> the post and pre consumption were determined, the savings were calculated based on the current <br /> The identified high water consumption faucets, urinals and showers should be replaced at this facility. <br /> The field investigation identified 25 restroom fixtures at the facility. After completion of the analysis, <br /> 15 replacement fixtures were proposed in the water conservation project shown below: <br /> Proposed Water Conservation Fixtures <br /> 4"Single Metered Faucet Dual Tem 0.5 GPM 9 <br /> 8"Siri le Lever Lounge Faucet with 0.5 m aerator 0.5 GPM 1 <br /> Wall Hung IM S ud'Elon ated Urinal—FV Infrared Control 0.125 GPM 1 <br /> Shower Head on Arm 2.0 GPF 4 <br /> Exclusions contain the following: <br /> • Existing low consumption water closets. <br /> • Existing low consumption showerheads. <br /> By replacing the existing fixtures and components with low flow units, the proposed consumption for <br /> the restroom fixtures is shown below. <br /> Water conservation has an annual savingst of $46, with a cost of $9,153, and a payback of greater <br /> than 100 Yrs. Therefore, FPLES does not recommend that Indian River County moves forward to <br /> implement the water conservation retrofit.
