Lighting Survey � � CITY OF ROSLASOUNT �XECUTT'tTE SUA�+�ARY FOR ACTI4N CTTY COUNCTL MEETING DATE; June 1., 1993 AGENDA ITEM: Lighting Survey P,GENb�i SEGTI02�S: Dep�rtment Head Report PREPARED BY: Ron Wasmund AGENDA �1�.� � � Public Works DirectorJBuilding Official i � � ATTACHMENTS; Comparison Sheets ED Y: ���=�-- , In January 1993 I had N.S.P. Electric do an Energy Use Analysis for City Hall to see if there was any potential for electrical s��vings. The analysis is done based upon the nuxnber of hours of operati�n, number.of light fixtures and types of light fixtures. N.S .P. eal.culated an annual savings of $7., 000. 72 and a one time rebate of $1, 033 .40 . To aehieve this savings a11 fluorescent fixtures need to be equipped with a new style light tube and new ballasts . The balance of the lighting fixtures in the building are state of the art and very efficient. To determine the true cost savings we then had to find out what the conversion costs would be� so we could uti].ize the new style �3.uoresGent tube, For this, Mr. Ted Hanson of Master Electric did another fixture study and an estimate for retrofitting the �ixture with new ballasts. While he was in the process I asked him to study the maintenance shop and fire sta�ion a1sc�. � have attached copies of his analysis and the results for your review. I will be most happy to go thrc�ugh the report in detail with you on Tuesday night �.f you desire. In summary, for City Hall the cost to re�rofit the light fixtures is $8, 851. By applying the one time rebate we have a net cost of $7, 1b3 . With an annual energy savings of $1, 6$0 we can recover our cost in approxirnatel�r 4 .3 years. The same process was taken with eaeh of �.he other �aci.lities. The shap results in a $454 annual savings with a 5 .1 ye�tr payback. The fire hall nets a $66Q annual savings with a 7.6 year pa�back. If this is a program the Council is interested in pursuing, I will budget the $17,806 for retrofit costs in the 1994 budget.
