Behavioral programs are increasingly popular, but little is known about their lifetimes. Retention drives calculations of behavioral intervention cost-effectiveness affecting TRC results, portfolio choice, and optimal program design. This study assembles existing literature on behavioral program persistence effects, including new research following post-program retention for four years. We detail both technical degradation (year-over-year savings / behavioral fall-off) and the lifetime (years with significant savings). The combination of the two provides the estimated or effective useful lifetime (EUL) for this behavioral measure, and we present results on lifetimes and revised cost-effectiveness from different demographic targets and program designs.
Behavioral Program Lifetimes: New Results & Implications for Cost-effective Program Design

10:30 AM to 12:00 PM
2017 HPC Northwest Regional Home Performance Conference & Trade Show
By attending this session, participants will:1. Understand the complexities of measuring lifetimes for behavioral measures
2. Learn new results for feasible lifetimes for typical behavioral programs and how it is affected by program targets and design3. Identify changes that can be made (cycling customers) that can deliver more savings at lower cost
