Adaptive Comfort In Buildings Located At The Hot Dry Condition Of Damaturu - Nigeria
Heat tolerance was measured in buildings located in hot dry area. The occupants of three buildings selected within the faculty of sciences, Yobe State University, Damaturu (Chemistry Laboratory, Physics Classroom and Lecture Hall B) were studied about their responses to peak values of thermal parameters for three consecutive days. The morning and evening measures were taken with (Thermometer, Anemometer and Hygrometer) where Thermal Comfort Questionnaire Survey was used in accessing the occupants. The results revealed that over eighty percent (80%) of the indoor users in each case were comfortable within higher values of thermal parameters. It was numerically recorded across the three buildings that when pMT was at (40 – 50) ºC while pRH and pV were constant, 86.3% of indoor users were comfortable within the indoor condition; but when pMT was at same value as above while pRH and pV set to outdoor condition, 77% of indoor users were comfortable within the indoor condition. The study concluded that heat tolerance in buildings increases in ratio of 1.12/1.0 with the decrease of outdoor air infiltration for users to become more comfortable indoor. School buildings should follow a reduced infiltration of outdoor poor thermal conditions in the area so that the required majorities (80) % were comfortable.
