INDIAN RIVER COUNTY PHASE 2 Y TECHNICAL ENERGY AUDIT RECOMMENDED ENERGY CONSERVATION MEASURES FPLES recommends that Indian River County moves forward to implement the lighting retrofit, as the ECM has the following savings and cost characteristics: e N/A $411532 12,886 7 107 430 229 8.4 Yrs (Note: The detailed analyses and cut sheets for this ECM can be found in Appendix H& I) ECM - 2: Occupancy Sensors FPLES performed an analysis of the facility's lighting system with respect to the use of occupancy sensors. It showed that additional savings for the selected rooms can be achieved adding the sensors. This is based on a review of the facility's occupancy pattern, lighting usage and FPLES historical data. For this facility, multiple rooms were selected for the installation of occupancy sensors and/or time switches which resulted in additional 3,384 kWh in savings. The models being used are shown in the Appendix and are for the various rooms (offices, conference rooms, storage rooms, mechanical rooms and electrical rooms). FPLES recommends that Indian River County moves forward to implement the occupancy sensors, as the overall"project"economics justifies the installation of such a system: Room ended_ NLA 380 4625 12.2 Yrs (Note: The detailed analyses and cut sheets for this ECM can be found in Appendix H& 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
