04/22/2013 participation in the audit and retrofit programs for municipal facilities that are funded by state, regional, county and utility programs. It further recommends targeting half the existing facilities for audits and implementation of energy savings projects by 2020 with 15 percent energy savings overall. Depending on staff time and resources, this Plan also recommends exploring using energy service companies for additional audit and retrofit opportunities beyond the publicly funded programs. Unfortunately, rising electricity costs can cut into the dollar savings from implementing energy efficiency projects in municipal facilities. Figures 1 and 2 show that the 15 percent energy savings target could represent as much as a $59,793 reduction in annual electricity costs over 2010, assuming the price of electricity remains the same as in 2010, but it would result in a $37,926 increase from the City's 2005 electricity cost due to an almost 20% increase in electricity costs from 2005 to 2010. If electricity costs do continue to rise, or if new buildings are added to the municipal portfolio, implementing efficiency projects becomes an effective cost control measure for the City.
