• Novel framework for PV-battery systems in multi-functional building complexes. • Real-world validation using ten-zone airport cargo terminal operational data. • Trade-off analysis reveals 60 % renewable share requires 14.5 % higher investment. • Cost-optimal configuration achieves 10.4 % savings at 0.49 CNY/kWh energy cost. This study addresses the challenge of designing cost-effective and energy-efficient solar energy systems for large-scale, multi-functional building complexes, which typically exhibit high and diverse energy demands. Although integrating solar power with energy storage has shown promise, existing research rarely considers the full complexity of such building types or the trade-offs between cost and renewable energy use. To fill this gap, this study develops a novel assessment framework that quantitatively evaluates system performance across both energy and economic dimensions. The framework is applied to a real-world airport cargo terminal comprising ten functional zones, evaluating six system configurations with different photovoltaic areas and battery capacities. Two optimization objectives are considered: maximizing the share of energy supplied by solar generation and minimizing the levelized cost of electricity. The results show that two of the six configurations stand out as most representative: Case 3 adopts full rooftop and façade photovoltaics with an 87.94 MWh battery, enabling 60 % renewable energy penetration and the highest overall performance...
