Most regions in Nigeria are notable for the hot and humid environments. This is attributed to
the major weather factors which in turn influences the indoor thermal comfort of occupants. Owing to the
economic constraints in the country, the choice of active air conditioning is often not realizable in public
university halls of residence. This leaves designers in this region with the only other option of passive
cooling applications in hostel building designs. Study identified that natural ventilation processes is
mostly dependent on regional windflow systems for wind driven ventilation. This paper examines the
impact of windflow systems around different building configurations adopted in the design of hostel
buildings in most Nigerian public universities. The atypical behavior of air movement which is necessary
for activating passive ventilation within these building forms is studied and the results justified the
effectiveness of building orientation for functional indoor ventilation.
