After the convenience that an automation system offers, energy management
is the main requirement as it pays the owner for a lifetime.
There is no room for experimentation at this point since
energy management is purely mathematical models.
The models calculate the rate of energy production
from renewable sources and the rate of consumption of the building and even predictably.
Thus, priority is given to the exploitation of cheap sources
and the combustion of fuel and the use of electricity from the grid is prevented.
In fact, today, when excess energy is allowed to be stored on the grid,
smart energy management monitors this energy storage and ensures
that it is consumed as the cheapest that has been stored on the grid.
