**2. Experimental Setup**

A green roof was installed ona building located on Benaguasil, a small town in the Mediterranean coast of Spain. As a reference, aclimograph of Valencia was included, which is the nearest city (at a distance of about 18 km and with similar altitude) with available weather data (Valencia weather station of Viveros). In Valencia, the average annual temperature is 23.0 ◦C during the day and 13.8 ◦C at night. In January (the coldest month), the temperature typically ranges from 14 ◦C to 20 ◦C during the day and 4 ◦C to 12 ◦C at night. In August (the warmest month), the average temperature registered over the last 80 years in Valencia was around 25 ◦C (Figure 1). Furthermore, specific temperature data of the Benaguasil area ranged from 28 ◦C to 34 ◦C during the day and about 22 ◦C at night.
