ENERGY-EFFICIENT DAYLIGHT HARVESTING SYSTEMS IN TROPICAL CLIMATES: A LITERATURE REVIEW

This paper delves into daylight harvesting systems and their vital role in enhancing energy efficiency in the tropics. Growing energy consumption in these areas, driven by factors like urbanization and population growth, makes addressing this issue a pressing concern. Buildings are significant contributors, accounting for 20-40% of global energy use. Tropical regions, facing unique challenges, can benefit from daylight harvesting to curtail energy consumption. Through qualitative analysis via desktop reviews, fundamental principles and technologies of daylight harvesting are explored, alongside successful case studies showcasing successful daylight harvesting implementations in tropical regions, emphasizing energy savings and improved indoor comfort. Despite challenges like intense sunlight and humidity, opportunities abound in leveraging abundant daylight, integrating passive design, and reaping environmental and economic benefits. This study emphasizes addressing energy consumption in tropical regions, focusing on daylight harvesting systems for significant efficiency gains and improved indoor comfort. Region-specific research is crucial for tailored strategies, while integrated design and continuous monitoring ensure optimal performance. Awareness, policy support, innovation, and collaboration are essential for widespread adoption and sustainable development in tropical building practices.
