This report addresses three major barriers to residential incentive uptake for single-family households: incentive availability and requirements, incentive stacking rules, and gaps in available incentives. This report includes:

  • A catalogue of the major federal incentives including a summary of existing stacking guidance.
  • A National Stacking Examples spreadsheet that walks step by step through how a resident would access incentives for retrofit services in order to evaluate and identify the barriers to stacking incentives.
  • A gap analysis identifying the gaps in participants served and the measures available for single-family households in addition to the complexities in accessing and stacking incentives.
  • A selection of concrete steps that state energy offices and other program administrators can take to improve access to incentives and facilitate stacking incentives to address upfront costs.
