ABSTRACT
This research examines the interplay between indoor environmental quality (IEQ), energy efficiency, and consumer behaviour within Ghana's Accra and Kumasi Malls. Combining IoT-based monitoring tools, building system data, and spatial behaviour tracking, the study assesses how temperature, CO₂ levels, lighting, and ventilation influence the duration of visitor stays. The analysis reveals that elevated temperatures and poor air quality decrease occupancy time, whereas good lighting and adequate ventilation promote more extended visits. A performance index indicates that Accra Mall attracts more visitors, but Kumasi Mall leads in environmental regulation and energy use. These findings underscore the importance of evaluating commercial spaces through both human-centred and technical dimensions. This study suggests that combining smart environmental controls with tailored design and policy can enhance occupant experience and operational outcomes in shopping malls. This promotes a shift toward more sustainable and responsive building management practices.
