**2.2.2 Natural stone products**

Slabs made of natural stone (mainly granite and marble) are used in urban squares, while stone blocks are used mainly in pedestrian and low-traffic streets. As was expected, white marble slabs were cooler than all the other natural stone materials. But dark grey marble and granite slabs recorded very high maximum surface temperatures, which were over 20 degrees above the corresponding air temperature. At 19:30 these materials were about 8 to 9 oC hotter than the air. Finally, it was observed that the surface temperatures of the shaded materials were very low.
