Consider replacing these with 13 watt CFLs with electronic ballasts, which would use about <br />13 watts each. If these lamps are ON about 2,500 hours per year, the savings would be 423 kWhr and <br />$41. <br />The 400 metal halide lamps in the parking/security lights each draw about 460 watts with their ballasts. <br />These could be replaced with pulse start ballasts which would draw about 355 watts each. Total potential <br />savings would be 7,740 kWhr and $740 per the year evaluated, based on 4,380 operating hours per year. <br />LED lights would provide significantly greater savings for this application-however, the present cost of <br />LEDs is very high. Replacement options should be reviewed periodically as costs are reduced and new <br />options become available. <br />Consider adding motion sensors to the lights in the lower level utility room to reduce the time these lights <br />are ON. Potential savings are dependent on reduced operating hours for the lights. <br />Water/Sewer <br />The 1,080,000 gallons of water used during 2010, is nearly 3,000 gallons per day, including weekends. <br />The City Hall is not charged for water orsewer-however, efforts should be made to minimize water use <br />with low flow plumbing fixtures and a culture of wa#er conservation at the facility. <br />Waste/ReCVClinq <br />The waste/recycling cost of $1,200 for the year evaluated seems reasonable for this facility. Efforts are <br />being made to recycle and compost materials as much as possible/feasible, to reduce trash. Section 5 <br />below provides guidelines for evaluating and possibly improving waste reduction and recycle programs. <br />Other <br />All computers, copiers, fax machines, and other electronic equipment should be turned off at night and on <br />weekends. <br />5: Solid Waste and Recycling Management <br />Following are guidelines for effective solid waste and recycling management. Not all this information is <br />necessarily applicable to your facility. <br />1. Level of Fill, Frequency of Pick-ups, Dempster Size, Compactor <br />Page 6 of 9 <br />
