Thermal comfort analysis for an in-between period (the autumn) the PMV index (
top
),
the PPD index (
middle
) and energy consumption (
bottom
)
Moreover, from the middle picture it can be inferred that the PPD index is inferior
to than 10% along these periods of time in which the heating system is working.

The autumn period. Figure
3.14
shows the results derived from the thermal comfort
analysis along the autumn period with the PMV and PPD indices. As can be seen
in the top picture of this figure, most of the time the PMV index is inside the
comfort zone. However, the 14 November was a cold day and it was necessary to
use the heating system in order to achieve the appropriate thermal conditions. This
hypothesis can be confirmed by means of the bottom graph in Fig.
3.14
, where
a considerable increment of energy consumption can be observed. Finally, in the
middle picture, the PPD index less than 20% along the whole period is shown.
