The Program's savings analysis of REM v15.7.1 (compared to v15.6.1) found negligible impacts. Moving forward, all REM homes will be processed in v15.7.1.
Please note that v15.7.1 allows for LED lighting inputs. Moving from 100% CFL to 100% LED can improve incentives by $150 to $250, depending on the size of the home. See the most recent technical bulletin on this topic.
