The authors investigated the impacts of seven residential rebate energy efficiency programs offered by a municipal utility. The evaluation examined energy use pre and post retrofit using the Advanced Mete1ing Infrastructure (AMI) data, disaggregated by major end-use and weather-adjusted; and also by detailed simulations. Residences modeled were representative of typical participants for that measure based on factors such as year built, conditioned square feet and number of bedrooms.
Our analysis found the residential rebate programs to be of highly varied effectiveness, but important differences surfaced between the simulation and the AMI data evaluation. Not surprisingly, programs with larger samples tended to better match the simulation results for annual energy use.
Our evaluation showed that the following rebate segments for existing single family homes were highly effective:
- ENERGY STAR Water Heater Program (HPWH)
- Duct Repair Program
- Window Replacement Program
- ENERGY STAR Clothes Washer
- Window Film Retrofit
- Wall Foam Insulation
- Solar Water Heating
