In Bahrain, electricity generation remains predominantly fossil fuel-based, contributing significantly to greenhouse gas (GHG) emissions and environmental degradation. Higher-education institutions, as energy-intensive facilities, present a strategic opportunity for sustainable energy transition. This paper investigates the feasibility of a 140 kW rooftop solar photovoltaic (PV) installation for Building A at the American University of Bahrain (AUBH). Using life cycle assessment (LCA), cost-benefit analysis, and ethical evaluation, the study quantifies environmental and financial outcomes while integrating circular economy principles. Results indicate that the proposed system, comprising 250 monocrystalline panels, can supply 40% of the building’s energy needs, reduce approximately 104 metric tons of CO2 annually, and achieve an energy payback time of 0.7-2 years. Economically, the project exhibits a payback period of 9.9 years with substantial long-term cost savings. Beyond financial metrics, the project strengthens sustainability education and aligns with Bahrain’s Vision 2030 climate objectives. These findings position campus-based PV deployment as a replicable solution for sustainable engineering in the Gulf region. © 2025 IEEE.
