The Financial Costs in Energy Efficient District. Alternative Scenarios from the Demo Sites of the CITyFiED Program

The European Union’s environmental policies actively promote the transition to a low-carbon society and to sustainable energy systems that improve people’s quality of life and do not negatively impact the natural environment. To achieve these goals, the European Union funded several programs to pilot energy efficiency measures for buildings and districts and, lately, launched the European Green Deal. The results of these experimentations have shown that often the economic feasibility of retrofitting interventions is not achieved without public grants. This contribution aims to analyze the influence of financial parameters on the profitability of projects of energy efficient districts. The study is based on the data from the demo sites of the CITyFiED program (Soma in Turkey and Laguna de Duero in Spain) that are reworked according to new several alternative scenarios, differentiated by cost financing and amount of public grants.
