This report consists of a literature review and in-depth interviews with subject matter experts in the Home Performance with ENERGY STAR (HPwES) program area. The goal was to compare Delaware Sustainable Energy Utility (DESEU) HPwES Programs with peer-programs across the United States. The report also identifies key metrics and emerging trends regarding program design.

Delaware Sustainable Energy Utility (DESEU) completed a process evaluation to assess the overall effectiveness of program operations. Evaluation activities included reviewing program materials, assessing the program flow, conducting in-depth interviews with program staff and implementers, and conducting surveys with contractors and customers. This report summarizes the key findings and recommendations from these process evaluation activities.

This report builds and expands off of previous research by collecting and evaluating data from 800 Illinois Home Performance (IHP) retrofits. This study investigates homeowner measure package choices in the Illinois Home Performance with ENERGY STAR® (IHP) program compared to cost-optimal choices determined through Building Energy Optimization (BEopt™) modeling software.

This report demonstrates the results achieved to date by the Southeast Energy Efficiency Alliance. It highlights the experiences of Consortium programs, their successes driving further investments in energy efficiency improvements, and the challenges that hindered their progress. It also details the infrastructure, resources, and opportunities that support the deployment of energy efficiency programming, and the approaches that the Consortium has found best suited to the region.

This interim evaluation report examines the design, delivery, and market effects of each of the Southeast Energy Efficiency Alliance's (SEEA) thirteen sub-grantee programs and identifies opportunities to increase each program's success, and quantifies and verifies the energy savings achieved through the programs' funded home energy improvements and the cost-effectiveness of those savings.
