Evaluation and feasibility studies of retrofitting interventions on social housing in Italy

While there is an increasing number of new projects aiming at combining high residential quality and low power consumption, it is clear that the main challenge in the short term concerns the performance upgrading of the existing residential buildings stock. The feasibility analysis should consider the economic implications of the retrofit projects. A Disocunted Cash Flow analysis can be implemented in order to investigate the economic aspects of such interventions. The DCF approach allows the analysis of costs as well as the revenues and savings with the objective of understanding the period of time needed to recover the initial investment.
