### Identification of Consumption Patterns  
The following graphs show the probability trends for different end uses; as an example, five typical houses have been used, but the methodology has been applied to all the houses that make up each of the transformation centers mentioned:  
The highest probability to use lighting, as shown in Figure 7, is from the sunset to the time when users go to sleep. Therefore, the curve shows a peak from approximately 18:00 to 23:00. Consumption is almost zero during night and starts rising between 6:00 and 7:00, when users initiate their daily activity. Regarding the probability of using the kitchen, shown in Figure 8, there are two peaks during the day, which correspond times in which users are preparing lunch and dinner. Regarding acclimatization end used, the probability of using the heating (Figure 9) is higher when there is no sun, while air conditioning (Figure 10) is more likely to be used during the central hours of the day.
