•
Insufficient manual control that was implemented in the HVAC system.
•
Existence of subjective factors in the evaluation of both thermal comfort and indoor
air quality.
In addition, both circumstances have, at the same time, consequences in the energy
consumption derived from the actuators since the inadequate operation of these sys-
tems, as well as their use out of their operation points cause performance and durabil-
ity losses. Hence, as a function of the comfort analysis that has been widely discussed
in this section, it is necessary to develop a specific control system which allows the
users to maintain environmental conditions of the building inside a comfort zone for
the user minimising, at the same time, energy consumption.
