INDIAN RIVER COUNTY PHASE Z <br /> TECHNICAL ENERGY AUDIT <br /> Exclusions include the following: <br /> • Existing LED exit signs. <br /> • Dimming Incandescent fixtures. <br /> In reference to existing lighting levels found in this survey, the building shows above average to <br /> adequate light levels and most of the areas have consistent lighting distribution. FPLES' lighting <br /> retrofit will improve the working environment by improving the lighting quality and <br /> levels in most areas. Although energy savings are the main objective, FPLES <br /> lighting retrofit will avoid sacrificing lighting levels in areas with existing low light <br /> levels to obtain greater savings (the estimated improvement in light levels in most <br /> areas are in a range of 5 to 10% in comparison with the existing light levels). <br /> FPLES recommends that Indian River County moves forward to implement the lighting <br /> retrofit, as the ECM has the following savings and cost characteristics: <br /> R <br /> NIA -t21834 188 1455 $17,372 S. Yrs <br /> (Note: The detailed analyses and cut sheets for this ECM can be found in Appendix H& I) <br /> ECM - 2: Occupancy Sensors <br /> FPLES performed an analysis of the facility's lighting system with respect to the <br /> use of occupancy sensors. It showed that additional savings for the selected <br /> rooms can be achieved adding the sensors. This is based on a review of the <br /> facility's occupancy pattern, lighting usage and FPLES historical data. <br /> For this facility, multiple rooms were selected for the installation of occupancy <br /> sensors and/or time switches which resulted in additional 3,318 kWh in savings. <br /> The models being used are shown in the Appendix and are for the various rooms <br /> (offices, conference rooms). <br />
