title = "Thermal assessment of different configurations of roof ponds for passive cooling",
abstract = "This paper discusses the cooling potential of two pond roof prototypes built and tested in a hot-dry climate with mild winters. The first roof consists of a pond covered with a floating insulating panel with a spray system above it that operates at night. The second roof is composed of a flat aluminum plate separated from the water by an air gap. At night, the temperature of the aluminum sheet falls below the temperature of the water, and therefore, the water vapor inside the roof condenses and falls by gravity. The potential cooling of a Water to Air Heat Exchanger (WAHE) has also been tested by connecting the cells with the ponds by a pipe through which the cell's air is re-circulated by a fan. We ran multiple series and compared the results to a control cell that had an energy code compliant insulated roof. Results demonstrate that both pod roof variants have higher cooling potential than the code compliant control cell. The best performance is obtained in the insulated roof with WAHE operating all time. In this case, the indoor temperature can be kept below 24 °C even with ambient temperatures above 35 °C.",
