Abstract
The ever increasing energy demand of sport centres highlights significant challenges in spatial planning, operational efficiency, and sustainability particularly within regions experiencing unstable electricity supply. This study assesses solar energy systems and their role in aiding spatial efficiency in selected sport centres in Lagos, Nigeria. A case study methodology was adopted, focusing on two major facilities within Southwest Lagos. Data were obtained through site observation, architectural layout assessment, and solar potential estimation of available roof and open spaces. Findings reveal that existing solar photovoltaic installations remain minimal, with heavy reliance on diesel generators and conventional systems occupying substantial service areas. However, both facilities possess high solar integration potential due to expansive long-span roofing and large parking zones suitable for photovoltaic deployment. Results further establish a positive relationship between solar energy integration and spatial efficiency, as solar systems optimize roof utilization, reduce generator infrastructure, and promote dual-use land functions such as solar carports. The study further concludes that incorporating solar energy systems into sport facility design and existing complexes can significantly improve energy sustainability and spatial performance outcomes.
