No of Days
In the afternoon, the relative humidity outside and inside the building followed the same pattern
and no clear difference was observed. This might be as a result of an increase in wind movement. The
relative humidity inside varies from 43.2% to 81.5% while the relative humidity outside varies from
40% to 82.7%.
In the evening, the pattern was not different from that of the morning, which implied that the
relative humidity conditions inside, the building was slightly higher than that of outside. The relative
humidity inside varied from 57% to 89.3% while the relative humidity outside varies from 56.6% to
87.6%, which was normal and within the comfort zone as stated by Seedorf, et al (1998).
Temperature Variations
The indoor and outdoor temperature varied with the periods of the day. In the morning the indoor
temperature was usually greater than that of outdoor temperature but in the afternoon the outdoor
temperature was a slightly higher than the indoor temperature. The indoor temperature in the morning
varied from 21.2 ºC to 27.1 ºC while the outdoor temperature varies from 21.7 ºC to 27.3 ºC as shown
in Fig.15. In the afternoon, the indoor temperature varied 26.1ºC to 34.6ºC while the outdoor
temperature varied from 26.9ºC to 36.3ºC as shown in Fig.16. In the evening, outside and inside
temperatures followed the same pattern as shown in Fig 17. The outdoor temperature varied from
25.2ºC to 33ºC while the inside temperature varied from 25.2ºC to 32.7ºC. This is considered normal
and within the thermo neutral or comfort zone of the birds (Van Kampen, 1997).
