Effects of natural light on improving the lighting and energy efficiency of buildings: toward low energy consumption and CO2 emission

Abstract

Abstract Findings from simulations and case studies reveal a significant reduction in energy consumption and CO2 emissions, with up to 30% improvement in overall energy efficiency. The framework demonstrates that combining natural light optimization with intelligent energy management systems can lead to sustainable building designs, fostering eco-friendly practices and reducing environmental footprints in urban infrastructure. Important results of the study show 24.81% environmental footprint reduction, 17.33% energy savings via daylight optimization, 92.75% energy efficiency gain, 94.39% effectiveness in energy management with Internet of Things integration, and 96.92% better illumination quality.
