Italian residential buildings are estimated about 12.42 million – more than 65% of which are over 45 years old, with ~56.4% of the whole National stock below energy performance class E and requiring deep renovation. Of this amount, 25% is composed of buildings with an energy demand from 160 – 220 kWh/m2 per year. Despite innovative financing mechanisms at National level (Ecobonus and Bonus Casa), the current deep renovation rate is estimated below the 0.85%. In order to increase this rate and meet the EU decarbonization and renovation rate goals, the Italian ecosystem is going to operate at National level but will deal with an heterogenous territory and unique assets. Putting together the experiences and networks provided by a triangulation of 3 key players, a strategy for the market uptake for industrialized retrofit will be drought on National level, acting both on the demand and supply side, by defining the potential of the use of that approach as well as the main barriers hampering that.
EURAC will share its knowledge on innovative products, technologies and tools for building retrofit with industrialized approach, as well as exploiting its network with industrial companies working in the field of energy efficiency in buildings.
GridAbility, via its ESCO R2M Energy, is an active player in Sardinia supporting ESCO models to develop turnkey renovation services and solutions – spamming from condominium to Local Energy Communities. R2M Energy is the promoter of the NESOI E(40)SCO Project
Ener2crowd is a crowd funding platform for green projects, willing to foster a fair and bottom-up energy transition. Ener2Crowd will provide an attractive financial instrument for investors, which will become direct contributors for the BuildUPspeed project.
Key focus of the Italian Ecosystem is the E(40)SCO project, located throughout the Cagliari municipal area (85 sq km). E(40)SCO has already been granted funding from the NESOI Project (https://www.nesoi.eu/) , with a total budget of 3,815,000 euros for a pre-feasibility study of deep renovation of 40 schools in the Cagliari Municipal area, with the objective of transforming 40 schools into 40 positive energy districts for the municipality. Moreover, the pilot site already gathered the interest of private partners in the energy sector (via the R2M energy ESCo. Models) willing to finance all or part of the plant interventions and manage the buildings several years necessary for the remuneration of the investment with the objective of impacting the energy saving and financial balance of the Municipality. At the same time, it provides a contribution to exploitation of deep energy retrofitting practices for a highly replicable building typology such as schools on the Italian Building stock – 73% of Italian schools belongs to the last three energy performance class (E,F and G) and only the 5.5% is in Class A and 1.7% in Class B, being in urgent need for energy efficiency interventions and comfort improvements for its occupants.
Concerning the renovation of building stock of schools, 500 million euros have been already put in the financial pipeline from the Italian government to foster schools stock renovation. This is a positive action, although further investments are needed on this side to drastically improve the existing situation, also taking into account that on the whole national territory around 50,000 schools are present. In this perspective, the identified financing approach and technologies and setting criteria can easily be a replicable example on a wider territorial scale of entire Sardinia Island, starting from the 17 municipalities included in the metropolitan City of Cagliari, where 431,000 inhabitants live on a territory of 1,248 sq km, moving to the other regions at progressive replication steps.
