Abstract: The present research investigates a new evaporative cooling technique, which is placed on the roof of a small building in the climate of Crete – Greece. A pond is filled with water up to 0.10–0.12m deep while an aluminium layer is kept 0.15 above free water surface, allowing ventilation between water level and the aluminium shield. The temperature of water and indoor air is recorded for a 35days summer period. The water temperature is analyzed, in regard to climatic conditions. According to the experimental records, the daily minimum temperature of water is practically equal to the corresponding air temperature while maximum daily temperature of water is about 8–13°C lower compared to the corresponding value of air.
