The effect of water-sprinkling on the surface temperatures of the materials used on the "skin" of greek cities

This paper focuses on the effect of water sprinkling on the fluctuation of the surface temperatures of materials, which are widely used in the urban open spaces of Greek cities, and are exposed to solar radiation. The assessment is based on experimental measurements, which were conducted during the summer period of 2004 on samples of building materials. The materials were placed on a flat roof and were periodically sprinkled with water.
