# Intelligent Reasoning Rules for Home Energy Management (IRRHEM): Algeria Case Study
## 4 Analysis and Discussion  
Through the obtained results, it can be seen that the value of the energy consumed by the IRRHEM solution intervention is less than or equal to the value of the energy consumed without the intervention of this solution, which proves the IRRHEM solution efficiency in many cases, including (Figure 10):  
* Energy savings of 81.39% and 56.73% are obtained during the periods of 05 h: 00 min: 00 s to 06 h: 00 min: 00 s and from 06 h: 00 min: 00 s to 07 h: 00 min: 00 s, respectively, based on:
* Turning off the \"air conditioner 6000 BTU\" in the parent's room;
* Turning off the \"air conditioner 6000 BTU\" in the boy's room;
* Turning off the \"air conditioner 6000 BTU\" in the girl's room;
* Switching off all the electrical equipment in the event of the absence of occupants; \begin{table}

Table 9: The obtained results using IRRHEM intervention. Contributing to the correction of negative characteristics of the family members, such as making mistakes in the use of electrical equipment, as well as forgetting to turn off equipment that is in a working state and not in use; * Adapting the rooms of the home according to the family members' wishes; * Grouping similar activities for adapting the rooms of the home according to the wishes of members (for example, \"Fajr\" prayer in congregation). * Energy savings of 85.84% were obtained during the period of 07 h: 00 min: 00 s to 08 h: 00 min: 00 min: 00 s, based on:
* Turning off the \"air conditioner 6000 BTU\" in the rooms of the parents, boy, and girl;
* Turning off the electric light bulbs in the rooms of the home (except in special cases) and taking advantage of the sunlight coming from outside of the house;
* When the family members are absent from a room, all electrical equipment is turned off (except in special cases, such as the refrigerator or security equipment);
* Correcting some negative actions of individuals, such as leaving a device running without it being needed, or forgetting to turn off a working device. In addition, through this solution, a room in the home can be adapted according to the personal preferences of the individuals, and also the similar activities of family members can be grouped together to be conducted at the same time (for example, the activity of eating meals together).
