Analysis of human heat stress status for academic learning environment in Kano University of Science and Technology, Wudil, Kano State, Nigeria.

Abstract

This study analysed heat stress condition and its implications on Academic activities of the KUST Wudil University. The Meteorological variables consisting of maximum and minimum wet and dry bulb temperatures data were collected from the KUST- Meteorological station from 2008 to 2011 and subjected to means simple statistic for determining heat stress condition by using Formulae of Discomfort Index (DI). The result reveals that DI values were 24.5, 26.5, 28.5 and 20 during the hot-dry, warm-wet, warm-dry and cool-dry seasons, respectively. These mean that the study area is vulnerable to severe discomfort condition, especially during the hot and humid season and during the afternoon hours when the influence of temperature and humidity elements are at their peak. This study recommends that (both passive and active mean of ventilation such as) air conditioners, surrounded with trees as well as the orientation of the building be taken into cognizance from the design stage for the effect of solar radiation on classes and rooms of the students/staff; Subjects that are mathematic based should be scheduled for morning period, while for the benefit of students the semester examinations should coincide with period around December or August when there is less risk of heat stress. The general idea presented is to illustrate the range of dimensions relevant to design and maintenance of an academic setting.
