### Comparison of Energy Consumption Based on the Comfort Model, Cities, and Scenarios  
The results of consumption in Figure 4 show significant differences in the energy consumption between the cities of Barcelona and Rome, varying between 883.07 and 1857.25 kWh/year according to the scenario and city, and in the cities of Berlin, Bern, and Vienna, between 2474.58 and 3705.98 kWh/year. The main reason is that Barcelona and Rome are located in warmer climates (Csa, according to [PERSON]) than Berlin, Bern, and Vienna (Cfb, according to [PERSON]). Focusing on the cities of Barcelona and Rome, results show that there are energy savings between 14.46 and 25.02% in heating, and between 46.83 and 66.22% in cooling, whereas the total energy saving achieved savings between 42.66 and 58.16%. On the other hand, Berlin, Bern and Vienna achieved energy savings between 7.03 and 12.85% in heating, and between 75.90 and 100% in cooling, whereas the total energy saving achieved savings between 14.49 and 26.42%.  
In all cases, the energy saving in cooling was greater than in heating. As for Barcelona and Rome, the reason could be that their climate is characterized by mild and high temperatures, and cooling consumption is greater. However, another reason could be that the temperature difference between static and adaptive setpoint temperatures was greater in cooling than in heating: In heating, the difference between the static setpoint temperature (18 \({}^{\circ}\)C) and the minimum adaptive (17.1 \({}^{\circ}\)C) was 0.9 \({}^{\circ}\)C, whereas in cooling, the difference between the static setpoint temperature (27 \({}^{\circ}\)C) and the maximum adaptive (32.7 \({}^{\circ}\)C) was 5.7 \({}^{\circ}\)C.  
Table 5 analyzes the different energy savings obtained in heating and cooling by using the ACCIM. Columns Static--Adaptive Heating Consumption, Static--Adaptive Cooling Consumption, and Static--Adaptive Total Consumption are the result of the subtraction of the adaptive consumption from the static consumption in the modes of heating, cooling, and total, respectively. The column Cooling--Heating is the result of the subtraction of the heating saving from the cooling saving (i.e., the first and second columns previously mentioned), so positive values mean that the cooling saving predominates over the heating saving, and negative values mean the opposite. In the cities of Barcelona and Rome, the cooling energy saving was considerably higher than the heating energy saving, between 853.41 and 1267.98 kWh/year. On the other hand, the energy saving in Berlin was greater in heating in all scenarios (varying between 67.49 and 448.51 kWh/year), except in the RCP8.5 scenario, in which the cooling energy saving was greater by 22.74 kWh/year. This tendency was similar in the cities of Bern and Vienna, in which the heating energy saving was greater in all scenarios (varying between 43.40 and 254.27 kWh/year), except in RCP4.5 and RCP8.5 scenarios, in which the cooling energy saving was greater between 58.24 and 527.69 kWh/year. In addition, the cooling saving in Vienna was slightly greater by 38.19 kWh/year than the heating saving in the scenario A1B.
