| Summary: | The evaporation rate varies according to temperature, humidity, and wind. The evaporation rate tends to be higher in the hot, dry months and lower in the wetter ones. This may affect the nation's energy use, indoor air quality, and water availability. This study conducted experiments under three conditions - uncovered, partially, and fully covered to ascertain the evaporation rate at UiTM Shah Alam, Malaysia. Recycled materials such as bottle caps were used in the experiment. The study examined the evaporation rate at UiTM Shah Alam in Selangor. The study discovered that the uncovered surface area evaporated at the highest rates in the morning, noon, and afternoon due to direct solar exposure. As some or all of the surface was shielded from the sun's rays, partially covered and fully covered surface areas had lower evaporation rates. It shows the evaporation rate for fully covered condition reduced 22 - 50 percent from uncovered condition. Meanwhile, evaporation rate for partially covered condition decreased by 10 - 17 percent compared to uncovered condition. The study offers important information about the variables influencing evaporation rate, which can be used to enhance understanding of evaporation processes and optimize evaporation in various applications. The findings may shed important light on the evaporation process and the variables that influence it, such as temperature, humidity, and cover material. The research results can be used to enhance building design and construction methods, increase building energy efficiency, and guide water management and conservation policies. © Published under licence by IOP Publishing Ltd.
