provided during day time. Figure 4.9 shows Fanger PMV values of 11 January and 18
August. Fanger PMV values are not more than 0.5 on 18 August; however, on 11
January these values change between 0.4 and 0.7. This result is provided by the fact that
the number of discomfortable hours decreased from 3.4 on 11 January to 2 on 18
August. Although summer averages may indicate better PMV index due to the night
temperature falls, these can not compansate the unpleasant hours of the day time.

Sensible cooling is is thermodynamically defined as the cooling with
temperature drop (contrary to latent cooling where no temperature drop occurs),
however; DesignBuilder user manual defines it as “cooling energy delivered to the
space from the HVAC system, including any “free cooling” due to introduction of
relatively warm outside air and any heating effects of fans” (DesignBuilder 1.2, User
Manual). Sensible cooling is needed both on a summer and a winter day (Figure 4.10).
There is also a minute amount of sensible heating is needed in some winter days. Figure
4.10 shows a comparison between August 18 th and January 11 th day time cooling energy
requirements. It is seen that the day time cooling energy requirement for a summer night
is twice as large as a winter night, whereas, day time cooling requirement is quadruples
between winter and summer, clearly the indication of solar gains.
