Global warming and increased air-conditioning demand drive up energy use. A passive cooling system for the building's roofs is one solution to this problem. The current study intends provide a unique evaporative concept building that use significantly less water than prior approaches. To reduce room temperature, saturated-activated alumina beds with 2, 4, 6 cm thicknesses were put over roof. Pure 35 PPT saline utilised evaluate performance sustainability. device successfully reduced rooftop temperatures by 84 % 70.9 after 24 h of testing (6 during daytime 18 at night) under heat loads 800 1000 W/m2. findings show salt feasible alternative freshwater does not sacrifice efficiency. From an environmental standpoint, compared bare roof, 6-cm layer saturated activated tables can annual carbon dioxide emissions 71.3 tCO2/m2 92 roof areas subjected daily solar radiation 6000 W h/day 4800 h/day, respectively.
