Fig. 4: The water saving capacity of RC films in greenhouses.
a Schematic illustration of the daytime radiative cooling and water saving ability of RC films in greenhouses. b Schematic illustration of the nighttime radiative cooling atmospheric water harvesting ability of RC films in greenhouses. c Water consumption and harvesting for a 500 m2 greenhouse covered with RC film during 100 days of planting. Relevant raw data are taken from refs. 69,70,71.
