RenOnBill promotes the development and implementation of on-bill schemes (OBS), to scale up investments towards deep energy renovations of residential buildings. RenOnBill focuses on five pillars: (1) scientific analysis serves to define the residential building market context, thus laying the foundation for replication in Europe. (2) Stakeholder engagement fosters cooperation among different actors to jointly develop national roadmaps for the replication of OBS in the RenOnBill in the four focus countries (Germany, Italy, Lithuania, Spain). The third pillar, (3) tool development, structures the residential sector’s energy renovation demand, by assessing risks and investments. (4) Pilots, the forth pillar test the results on the three partner utilities, for which tailored business models are developed. The last pillar, (5) related to exploitation and dissemination, ensures that the projects results reach the relevant groups and are effectively disseminated even after the end of the project.
