Abstract: This paper sought to determine the effects of design strategies on thermal comfort in naturally- ventilated student hostels. The review of related literature led to the postulation of two null hypotheses which served as a guide to the study. The data were collected via computer fluid dynamics (CFD) and simulations using the PHOENICS-VR programme. The principal component analysis (PCA), analysis of variance (ANOVA) and Pearson product-moment correlation were used in the data analysis. The results revealed a significant correlation between design strategies hinged on ventilation, temperature and relative humidity with passive ventilation for thermal comfort. The results also confirmed the degrees of effectiveness of the different design strategies and ranked them in the appropriate order for effective passive ventilation and thermal comfort. Some recommendations were made, while new areas were suggested for further study.
