**2. Methodology**

Figure 1 shows the diagram of the methodology used in this study and the three analyses that were performed: (1) the weather data comparison between the data provided by the *on-site* weather stations and the *third-party* data; and through energy model simulations using these two weather datasets; (2) the energy demand comparison; and (3) the indoor temperature comparison.

**Figure 1.** Diagram of the methodology used to check the effect of the use of different *actual* weather data in the building energy simulations. Three analyses are performed in the study: weather data comparison (methodology explained on Section 2.1), energy comparison (Section 2.2), and indoor temperature comparison (Section 2.3).
