摘要：The construction of new buildings or interventions to improve energy performance can be considered "sustainable" if they meet the requirements which intersect with each other in the economic, social and environmental spheres. The paper has as its main topic detecting and quantifying the market premium attributable to housing properties with high energy performance characteristics. Through a semi-parametric additive model, extended to a wide real estate sample relating to the city of Reggio Calabria, it is demonstrated how the choice of sustainable interventions, oriented to "Green Building" practices, produce significant economic impacts in terms of increased market value of buildings as well as mitigating energy consumption while respecting the historical-architectural peculiarities of urban buildings.
