#### 3.3.4 Future Climates--Scenario RCP 8.5  
Figure 17a,b present the water content profile for the selected two spells for the near future for RCP 8.5 (Table 6), while Figure 17c,d show the respective precipitation for each spell. The two spells show the results for an extra 24 h after the spells end because they had a substantial precipitation event right before their end (Figure 17c,d). Figure 17a shows the water content for the first selected spell, which lasts for 304 h and has a total precipitation of 33.1 L/(m2h). The highest water content value of 13.6 kg/m2 is attained on 28/01 at 06:00, while the lowest water content value of 3.0 kg/m2 is attained on 27/01 at 15:00. It is visible that before the spell begins (i.e., 27/01 at 09:00), the water content value throughout the assembly is rather low. This means that the assembly is able to dry from the previous spells. However, as soon as the spell starts, the water content increases firstly on the exterior surface, which then spreads to the remainder of the assembly. In addition, it is also visible that the extra 24 h for drying are not enough for the brick to dry, but some substantial differences are already observed for the lime layer (Figure 17a, purple and green lines). For this case, the moisture originating from outdoors is able to reach a depth of 129 mm at 17.0 kg/m\({}^{3}\) (Figure 17a). Figure 17b shows the water content for the second selected spell, which lasts for 94 h and has a total precipitation of 17.2 L/(m\({}^{2}\)h). This spell is shorter than the first spell (69.1% shorter), and the precipitation is lower (48% lower). The highest water content value of 13.6 kg/m\({}^{2}\) is attained on 05/11 at 02:00, while the lowest water content value of 3.4 kg/m\({}^{2}\) is attained on 02/11 at 15:00. It is interesting to notice that the highest average water content is attained not right after the most significant WDR spell, i.e., 04/11, but nearly at the end of the spell. It is visible that before the spell begins (i.e., 01/11 at 10:00), the water content value throughout the assembly is rather low with the exception of the exterior surface. Since the value is still far from the mortar maximum storage capacity (Figure 3), this means that the initial WDR spell is sufficient to increase the water content at the exterior surface. It is visible that after the spell starts, the amount of moisture within the assembly increases considerably, and there is a significant difference between the end of the spell and 24 h later, especially nearer to the exterior surface for the mortar and nearer the interface for the brick (Figure 17b, purple and green lines). For this case, the moisture originating from the outdoors is able to reach a depth of 94 mm (Figure 17a), which is not as deep as for the first

The blue lines in (**a,b**) correspond to water content across the assembly for any given period within the corresponding spell limits. spell (Table 7). This is probably because the spell is shorter as well as due to the amount of rain that impacts the wall. Figure 18a-c present the water content profile for the selected three spells in the far future for RCP 8.5 (Table 6), while Figure 18c-e show the respective precipitation for each spell. The last two spells show the results for an extra 24 h after the spells have ended because they had a substantial precipitation event right before the spell ended (Figure 18c,e). Figure 18a shows the water content for the first selected spell, which lasts for 362 h and has a total precipitation of 31.0 L/(m\({}^{2}\)h). The highest water content value of 13.0 kg/m\({}^{2}\) is attained on 16/02 at 19:00, while the lowest water content value of 3.0 kg/m\({}^{2}\) is attained on 05/02 at 14:00.
