2.4.1. "Call" Concept

There are many similar individuals' activities that can be grouped in a single time (for example, eating meals), so that there is the joint use of devices that consume electricity, and thus benefit from an important energy saving method. It is only a reminder that the process of grouping activities can be carried out without neglecting the comfort of the residents. To ensure the latter, it is necessary to first collect the activities in a unified and short time, and if this process causes harm to an individual, the time is expanded to be slightly longer and therefore electricity consumption can also be obtained, but in a smaller amount than in the first case (Figure 3).
