EVALUATING INDOOR ENVIRONMENTAL QUALITY FOR PRODUCTIVITY OPTIMIZATION IN NIGERIAN UNIVERSITY ENTREPRENEURSHIP CENTERS

This study evaluates Indoor Environmental Quality (IEQ) in selected Nigerian university entrepreneurship centers to assess its impact on user productivity and propose optimization strategies. Focusing on three case studies, a federal, state, and private university, the research examines five key IEQ parameters: thermal comfort, indoor air quality (IAQ), visual environment, acoustic conditions, and spatial ergonomics. Using a qualitative case study approach with structured observational checklists, the study identifies critical deficiencies, including inadequate ventilation, uneven lighting distribution, poor acoustic treatment, and non-adjustable furniture. Findings reveal that while natural lighting is abundant, thermal regulation remains suboptimal due to passive adaptation strategies (e.g., closed blinds, limited airflow). The absence of sound-absorbing materials and ergonomic furniture further compromises workspace functionality. The study highlights discrepancies between observed conditions and established IEQ standards (ASHRAE, WELL Building Standard), emphasizing the need for context-specific improvements in Nigeria's tropical climate. Recommendations include immediate low-cost interventions (e.g., installing acoustic panels, adjustable window treatments), medium-term upgrades (e.g., ergonomic furniture, task lighting), and long-term policy integration of IEQ standards in educational building codes. In addressing these gaps, Nigerian entrepreneurship centers can enhance cognitive performance, creativity, and business incubation outcomes. This research contributes to the limited literature on IEQ in African educational workspaces and provides actionable insights for optimizing innovation hubs in developing economies.
