The sustainable energy transition of communities is one of the main targets within the European energy policies. Consistent energy planning is needed but conditioned by difficulties of city administrations to meet the necessary skills and have the necessary knowledge in order to lead the corresponding transition processes. The R4E project (www.roadmapsforenergy.eu) responds to the EE-07-2014 call entitled “Enhancing the capacity of public authorities to plan and implement sustainable energy policies and measures” within the Secure, Clean and Efficient Energy Work Programme of HORIZON 2020 of the European Commission R4E develops roadmapping capacities of 8 European partner cities (Eindhoven, Forlì, Istanbul, Newcastle, Murcia, Palermo, Sant Cugat and Tallinn) together with their local stakeholders, and provides them with the necessary knowledge about innovative energy solutions in the fields of smart buildings, smart mobility and smart urban spaces. A specific systemic approach to these future energy solutions has been developed, based on Deskstudies, Experts interviews and resulting Generic Roadmaps. The Deskstudies consist in Systemic Solution Maps, Technology Outlooks and Case Studies building a systemic knowledge generation tool for participants in multi-stakeholder processes. First applications and the feedback of stakeholders of city partners will be presented at the conference, discussing the usefulness of the approach for the city partners. The R4E project received funding from the European Union's Horizon 2020 research and innovation program under grant agreement Nº 649397.
