Building renovation between CAM and Superbonus: limitations and prospects for mass retrofitting

This paper reflects on the results of the recent technical policy for energy requalification in Italy, focusing on both the European objectives of decarbonisation, circularity and industrialisation of the sector, and the size and characteristics of demand. Starting from the comparison between the two main models of efficiency of the public and private building stock, based respectively on the Minimum Environmental Criteria and the Superbonus, the study examines the effectiveness and limitations of the measures for private construction, which constitutes the majority share of the entire Italian building stock. The study identifies the Energiesprong model as a possible way to improve the management and quality of energy requalification interventions capable of expanding their effectiveness beyond the environmental point of view.
