Thermal Load Assessment and EnergyEfficiency Enhancement in SchoolBuildings: A Case Study of A School Building

الملخص

Comprehensive study presents a detailed thermal load assessment and energy efficiency analysis of school buildings in Gharyan, Libya, with a focus on sustainable energy solutions and climate-responsive design strategies. The research addresses the critical gap in energy-efficient building practices in Libya's educational sector, where 95% of public schools rely exclusively on natural ventilation systems. Through rigorous thermal modeling and performance analysis of a representative two-story school building (910 m²), this study quantifies heating and cooling loads while evaluating the potential impact of cost-effective energy efficiency measures. The methodology employs established ASHRAE standards and thermal analysis techniques to assess building performance under Libya's hot-arid climate conditions. Key findings reveal that infiltration accounts for the highest thermal loads, while lighting and equipment contribute minimally to overall energy consumption. Implementation of comprehensive energy efficiency measures—including wall and roof insulation upgrades and high-performance window replacements—demonstrates a significant 25% reduction in total building thermal loads. This research contributes to the growing body of knowledge on energy efficiency in educational buildings within developing countries, particularly in North African contexts. The study's findings support Libya's renewable energy targets of achieving 4GW capacity by 2035, representing 20% of the national energy portfolio. The proposed energy efficiency framework provides actionable insights for policymakers, architects, and educational administrators seeking to optimize building performance while reducing operational costs and environmental impact
