In particular, the retrofitting of an existing district for reducing energy demand to very low values, improving the generation facilities and the supply of energy for a better use of the local resources (use of renewable) and higher efficiency (use of district scale system), in order to achieve low energy districts (renewable district heating and cooling, PV,CHP,… ), substitute a high number of conventional vehicles by clean vehicles, improving in parallel the associated infrastructures and the management (for instance electrical vehicles and charging infrastructure) and finally improving through ICT solutions the management of some of the city infrastructures, as the smart grids or the traffic management systems.
A financial and feasibility plan has been developed in order to guarantee the investment and the return of them.
The cities that are committing an intervention are Valladolid, Nottingham and Tepebasi/Eskisehir. These lighthouse cities also commit the deployment of a powerful monitoring system, in order to gather the necessary variables for the evaluation procedure that will be designed in a previous stage.
Further that the technical actions, these interventions will include a relevant citizen engagement activity for maximizing the impact and achieve a wider validation. The large scale demonstrations are a part of very ambitious urban plans.
