In the future scenario 2050 of climate change with warmer exterior temperature conditions, we see that there is a drop of 33% in the demand for heating in all the cities. The demands of the Case Study in 2050 are, depending on the places, between 25 and 45% lower than in the present-day Case Study. We also see that the order described for the cities coincides with greater to lesser demands. In this situation, Mostar in the Case Study has demands of between 74.2 and 98.7 kWh/m2 yr and Valencia has between 18.9 and 37.5 kWh/m2 yr. The demands of T5 are always higher than T3 and the latter is higher than T1. With the M1 level, savings are produced of between 59 and 79%, with the demands for Valencia being between 3 and 7 kWh/m2 yr and the remaining cities having demand values of under 30 kWh/m2 yr, except for Mostar and Nîmes which are slightly above this value. With M2, savings of between 85 and 100% are achieved, and all the cities have demands below 5 kWh/m2 yr except Mostar and Nîmes, which, in T5, have values of 10 and 8 kWh/m2 yr, respectively. This shows not only the effectiveness of the insulation but also of the incorporation of heat recovery systems in ventilation.
