As is known, the Italian Ministry of Economic Development has launched a review of the National Energy Strategy. This revision is necessary, given the climate targets for 2030 and the swift entry into force of the Agreement of Paris. In the building sector a remarkable qualitative leap forward will be required. The greenhouse gas emissions, whose levels have been stable over the past 25 years due to the energy consumption growth in the service sector, will indeed have to be reduced by 15-20% by the end of the next decade, according to the objective set for Italy (-33% compared to 2005) for non-energy intensive sectors, that is those not covered by the Emissions Trading System.
It will therefore be necessary to arrange new incentive systems that will gradually shift the focus from efficiency measures on individual apartments, typical of the tax credits of 65%, to measures directed to entire buildings in order to get stronger energy consumption reductions (-50-70%). A first signal has been noticed with the Law of stability of end 2016, but it is possible to figure out even more effective tools, such as those suggested by Enea and Green Building Council Italy which provide for the involvement of “Cassa Depositi e Prestiti” to anticipate large amounts of the needed capital.
At the same time, it is also necessary to increase the level of offer of the building sector, taking advantage of the opportunities provided by innovations in materials, system solutions and organizational tools. One interesting path that has applications in some specific contexts concerns the industrialization of the energy renovation process, started with the Dutch experience of Energiesprong that is spreading in France, UK, Germany and is being introduced also in our Country. The cost reduction of 40%, the drastic shrinkage of time needed (3/4-storey buildings regenerated in 2-3 weeks) and the resetting of fossil fuels, make this approach particularly significant.
