INDIAN RIVER COUNTY PHASE 2 TECHNICAL ENERGY AUDIT RECOMMENDED ENERGY CONSERVATION MEASURES FPLES recommends that Indian River County moves forward to implement the occupancy sensors, as the ECM has the following savings and cost characteristics: R m N A IJbz 12,721 7.5 Yrs (Note: The detailed analyses and cut sheets for this ECM can be found in Appendix N& I) ECM - 3: Water Conservation FPLES performed a walkdown of the facility's domestic water system with respect to installing low flow and. ultra low flow fixtures. As a result, it was determined that savings can be achieved through the replacement and/or retrofit of water fixtures. The analysis included determining the consumption of the existing (pre) fixtures, comparing it to the baseline water bill (see Modeling Methods, Section 3) and determining the consumption of the retrofit (post) fixtures. Once the post and pre consumption were determined, the savings were calculated based on the current water/sewer rates. The identified high water consumption faucets, water closets, and urinals should be replaced at this facility. The field investigation identified 10 restroom fixtures at the facility. After completion of the analysis, 9 replacement fixtures were proposed in the water conservation project shown below: Proposed Water Conservation Fixtures 111 1111111 NNIIIIIIIS 4"Sin le Metered Faucet Single Temp 0.5 GPM 3 Floor Mount Dual Flush Water Closet-Tank 1.6/0.8 1.0 GPF 3 Floor Mount Dual Flush Water Closet ADA-Tank 1-6/0.8 1.0 GPF 2 Wall Hung Top Sud Urinal—FV 0.125 GPF 1 Exclusions contain the following: • Existing low consumption faucets. Water conservation hasan annual savings of $503, with a cost of$12,898, and a payback of greater than 25 Yrs. Therefore, FPLES does not recommends that Indian River County moves forward to implement the water conservation retrofit.
