ABSTRACT
This research investigates the potential of piezoelectric floor tiles to harness kinetic energy in shopping malls across Ghana. Focusing on installations in high-traffic areas at Accra Mall and West Hills Mall, simulations and small-scale pilots were used to evaluate performance and financial viability—a 10 m² array produced between 1.15 and 3.46 kWh daily, with observed data closely mirroring projections. Notably, energy output peaked in zones with constant foot traffic. Thus, entrances and food courts proved especially productive. Financially, the setup showed a payback range of 6 to 8 years, translating to annual savings of GHS 584 to GHS 1,582 per year. While the generated energy is insufficient to run entire facilities, it presents a practical solution for powering LED signs. The study suggests that, beyond function, such systems could serve as visible symbols of sustainable innovation in developing urban centres. For commercial property managers, this study provides a strong case for focused deployment in commercial areas to maximize return on investment.
