•
The summer period. As shown in the top picture of Fig.

, there are some days in
which the PMV index is outside the comfort zone and other days where this index
is inside the comfort zone. Moreover, if the top picture is compared to the bottom
graph, it can be observed that there is an increment in energy consumption those
days in which the PMV index is located inside the comfort zone. From this, it can
be inferred that the environment was occupied and besides the HVAC system was
working. Finally, in the middle figure it is shown that although the PMV index was
equal to zero, there is a percentage of people approximately equal to 5% which is
dissatisfied with the thermal environment. Furthermore, when the room is closed
