On conventional roofs, the solar energy absorbed is essentially released as Sensible Heat and Thermal Radiation.
\nThe large percentage of sensible heat causes a considerable rise in temperature and negatively impacts the tolerability of the surrounding microclimate.<\/p>\n

On a green roof, on the other hand, a considerable fraction of energy is stored by the newly created substrate (new soil) and then used by the plants to evaporate water using Latent Heat (evapotranspiration).

Up to 60% of net solar radiation is absorbed<\/strong> and used for Chlorophyll Photosynthesis and Evapotranspiration, reducing Latent Heat<\/strong> (Schmidt 2010; Takebayashi & Moriyama 2007; Berardi et al. 2014).
The result is a lower percentage of Thermal Radiation and Sensible Heat released into the surrounding environment.<\/span><\/p>\n
