Assessment of Indoor Environments in University Student Accommodation: Evidence from Nigeria

Poor indoor environmental quality (IEQ) in Nigerian university accommodation can negatively impact students' health, comfort, and academic performance. IEQ was assessed in 6 hostels using field measurements and surveys of 442 students. In male hostels, poor ventilation and indoor activity led to significantly higher levels of PM2.5 and PM10 compared to WHO standards. Poor ventilation was seen in female accommodation, as shown by CO₂ trends. Poor IEQ was substantially related with reported symptoms such as respiratory issues, headaches, and frequent sickness. The study suggests improved ventilation, maintenance, and statutory modifications to improve student health and learning.
