**Table 6.** Summary of interventions and related changes.

Figure 12 depicts the electrification degree resulting from the 15 proposed interventions and combinations of them. In the status quo, the average electrification degree, i.e., the ratio between electrical loads and total ones, is 34%. Conversely, the highest value is reached in all the interventions apart from #10 which is 33.8% since the electric loads are reduced making the cooling supply more efficient. Interventions #5, #11, and #14 increase the mentioned parameter thanks the high reduction of heating consumption while interventions #7, #9, #12, #13, and #15 achieved the highest values switching the heating from fossil-based to electric-driven.

Figure 13a shows the flexible loads in percentage value in part while, in absolute values in Figure 13b. Strong changes are found only for the electrification of the heating systems by means of heat pumps for heating and/or for DHW. Those interventions are #7, #9, #12, #13, and #15.

Finally Figure 14a depicts how the frequency of flexible loads is before the intervention #0, and in Figure 14b after the comprehensive renovation #15. In the latter, 40% of dwellings show flexible loads lower than 1400 kWh/y. If the value 1800 kWh/y is considered, 60% of the analyzed residential building stock is under it. Only 32.2% of dwellings have more than 2000 kWh/y flexible loads.
