Persistence of behavioral programs: New information and implications for program optimization

More studies on retention of impacts from increasingly popular behavioral energy efficiency programs are needed to allow programs to be credited with all their attributable effects, accurately assess cost-effectiveness, and optimize program design and delivery. This study reviews recent retention results for home-energy report-type (HER) programs, examines technical degradation function (TDF) and falloff, and provides sample calculations on program cycling for improved cost-effectiveness.
