The methodology used, based on the urbanZEB tool, allows an energy simulation and economic characterisation of the 50,647 dwellings in the area. This large-scale diagnosis forms the first database, on the basis of which the distribution of Menorca’s dwellings into packages with similar characteristics is carried out, following the logic used in the ERESEE 2020. These packages of dwellings allow the roadmap to 2030 to be drawn up and the rehabilitation path to be defined according to the characteristics and criteria defined by the CIME. As a final product of the work, a tool is developed to define the energy impact (savings in heating consumption) as well as the economic impact (cost of refurbishment intervention and equipment), based on the prioritisation criteria introduced.
