This study investigates the conditions and the levels of satisfaction with indoor environmental quality (IEQ) in naturally ventilated (NV) learning environments in Bayero University, Kano and compares the results to international comfort standards’ thresholds. It examines the thermal and visual comfort, acoustic quality as well as the indoor air quality of six learning environments in the University consisting of four lecture theatres and two laboratories. Researches in IEQ have shown that...

As the international comfort standards may not be appropriate for all climates, it is imperative to evaluate the comfort requirements of indoor occupants in all regions of the world, particularly in the tropical regions where comprehensive standards are lacking. It is usual to find learning spaces in Nigerian higher institutions in which the thermal qualities do not meet the occupants’ requirements. Despite being in the tropics, where solar radiation is in abundance, Nigerian building...

It is well known that thermal comfort is influenced by major physical parameters; air and radiant temperatures, humidity, and air speed in combination with personal attributes; clothing insulation and activity level. Although temperature is conventionally considered in adaptive thermal comfort model, as the most important physical parameter where cooling is involved, moderate air speed can enhance thermal comfort during higher temperatures. Through convective and evaporative cooling, ceiling...

Poor environmental comfort in learning spaces can have an impact on the learning capacities of students. It is not unusual to find learning spaces in Nigerian higher institutions in which the indoor environmental qualities do not meet the occupants’ requirements. Despite being in the tropics, where solar radiation is in abundance, Nigerian building industry professionals pay little attention to passive energy utilization. Knowing how buildings perform in the country may appeal to their...
