closed loop, although the use of feedback to perform an appropriate decision-
making is preferable.
In both approaches, multilayer and multilevel control, the common characteristic
is that there exist different units of decision-making, although only some of them
have a direct access to the controlled system. The rest of the units are located in a
higher level of the hierarchy, and thus, they have to coordinate and define the different
tasks that must be carried out by the lower layers of the control architecture.
In accordance to themain objectives established for comfort control, a hierarchical
multilayer control architecture able to generate, in the higher layer, the suitable
