This report details an evaluation of Orlando Utilities Commission (OUC) residential energy  efficiency demand side management (DSM) programs to assess their impacts and relative  measures of energy and economic performance. The primary objective of the end-use billing  analysis is to estimate energy savings attributable to three of OUC’s residential energy efficiency  rebate programs, including seven individual retrofit measures. This analysis addresses the need to develop methods for characterizing existing housing stock, and understanding the energy and  monetary benefits of making specific residential energy efficiency retrofit investments. Retrofit loan program criteria can incorporate historical energy savings estimates for local retrofit  programs by providing a basis for prioritizing and targeting specific retrofit programs that are  likely to optimize efficiency gains.
