INDIAN RIVER COUNTY PHASE 2 <br /> TECHNICAL ENERGY AUDIT <br /> 1 <br /> RECOMMENDED ENERGY CONSERVATION MEASURES <br /> Exclusions: <br /> • Control system connection to County LAN line. <br /> • Painting <br /> • Temporary Cooling during replacement <br /> • Repair of existing pipe insulation not associated with replacement of chiller and pump. <br /> As a result, the impact of replacing the existing air cooled chiller with a new high efficiency air <br /> cooled chiller and replacing the existing chilled water pump with a variable speed chilled water <br /> pump is recommended,as the overall "project"economics justifies the installation of such a <br /> system. <br /> Itecommended <br /> NLA $18,307 1373,949 20.4 Yrs <br /> (Note: The detailed analyses and cut sheets for this ECM can be found in Appendix ]& K) <br /> Health Department Summary <br /> $261278 16488 $442,505 16.4 Yrs <br /> (Note: the overall"project"economics justifies the inclusion of this facility) <br /> Old Health Department <br /> FPLES investigated the feasibility of implementing lighting retrofits and water <br /> conservation at the facility. The results of the analysis are listed below. <br /> After detailed engineering analysis, FPLES has identified cost-effective ECMs that <br /> will help the County: 1) reduce its operational energy and utility expenses, 2) <br /> relieve capital expenditures for other critical improvements; 3) relieve service and <br /> upkeep expenses; and 4) provide a comfortable indoor environment to its <br /> occupants. <br /> ECM - 1: Lighting Retrofit <br /> The field investigation identified 115 lighting fixtures at Old Health Department. After completion <br /> of the analysis, 109 fixtures have been included in the lighting retrofit shown below: <br />
