Experimental analysis of an extensive green roof in Mediterranean climate.
From 26% to 35% of incident solar radiation lost by evapotranspiration in summer.
A reduction of 100% of the thermal energy entering the indoor environment in summer.
A reduction between 30% and 37% of the outgoing thermal energy in winter.
A minimum decrement factor of 0.135 and a maximum time lag of 4.8 h are obtained.
