The government of Nigeria has been making effort in providing adequate infrastructure for teaching and learning through the Tertiary Education Trust Fund (TETFund) grant, however, this effort has not yielded significant results, as many tertiary educational buildings still fail to demonstrate sustainable Indoor Environmental Quality (IEQ). The study assessed students’ satisfaction with IEQ of tertiary educational buildings in Nigeria with the Federal University of Technology, Akure as a case study. Students’ satisfaction with indoor environmental quality was assessed through a questionnaire survey of IEQ factors. The population for the study were the general lecture halls used by 100–300-level students of the School of Environmental Technology (SET).Three hundred and thirty-eight (338) copies of the questionnaires were administered to the respondents. Data collected were analyzed using mean item score and Relative Importance Index (RII). Respondents identified ventilation as the most important IEQ factor as it ranked among all other IEQ factor. Results showed that students were more satisfied with the level of control in all lecture theaters while available workspaces had the most significant effect on the students’ performance. However, students expressed dissatisfaction with the thermal and acoustic conditions of the lecture halls, indicating a need for significant improvements in these areas to enhance both learning and productivity. Therefore, the study recommended that post occupancy evaluations are done to plan for better, sustainable and environmentally friendly buildings. It is also fundamental to enhance the design and provision of workspaces in future lecture halls to comfortably accommodate the growing student population and support effective learning.
