# Dynamics of Changes in Climate Zones and Building Energy Demand. A Case Study in Spain
## 3 Results and Discussion  
After applying the previous section's methodological steps, the results shown in Figures 2-7 and Tables 3-5 were obtained, which are analyzed and discussed below. Figure 3: Calculated indices of winter (WCS) and summer (SCS) climate severity for the RCP 4.5. Figure 4: Calculated indices of winter (WCS) and summer (SCS) climate severity for the RCP 8.5. Figure 5: Boxplots of values of the WCS (**a**) and SCS (**b**) indexes in 7967 localities in mainland Spain for the period 2015–2018 and future periods. Figure 6: Maps of (**a**) CTE, (**b**) climatic zone by the period 2015–2018, (**c**) climate zones for RCP 4.5 2055, (**d**) climate zones for RCP 4.5 2085, (**e**) climate zones for RCP 8.5 2055, (**f**) climate zones for RCP 8.5 2085. Figure 7: Dynamics of changes in the average of heating and cooling energy demand for the RCP 4.5 and RCP 8.5 scenarios by 77 stations. \begin{table}
