A Cost-Benefit Analysis based model to evaluate the retrofit of a reference district

Due to the role of cities in driving the transition to a more sustainable future, an urban level perspective becomes fundamental to support decision-makers in defining long- term coordinated strategies. The driving idea of this paper is to examine different urban retrofit scenarios and study them from an energy, environmental and economic point of view assessing their sustainability at the district level. Energy savings and avoided emissions by different cross-sectorial strategies were calculated, with a particular focus on buildings. Secondly, a socio-economic model was developed through the Cost-Benefit Analysis to delineate the most suitable combination of retrofit actions.
