A utility program considers four key variables when assessing the cost-effectiveness of an energy efficiency measure: energy savings, peak demand savings, measure costs and effective useful life (EUL). Of these four variables, programs typically place the least emphasis on setting and updating measure costs. For this analysis, we explore measure costs by mining program participant data across multiple regions over a four year period. Our analysis focuses on a select group of top retrofit measures in commercial programs, where the incremental cost is equal to the full measure cost. We examine how costs change year-to-year and across different geographic regions.
