Green roofs have a thermal insulating effect known since ancient times.In the building sector, green roofs represent a sustainable passive solution to obtain energy savings, both during winter and summer.Moreover, they are a natural barrier against noise pollution, reducing sound reflections, and they contribute to clean air and biodiversity in urban areas.

In this research, a roof-lawn system was studied through a click here long experimental campaign.Heat-flow meters, air and surface temperature sensors were used in two buildings characterized by different surrounding conditions, geometries and orientations.In both case studies, the thermal behaviors of the roof-lawn system were compared with the conventional roofs.

In addition, a dynamic simulation model was created in order to quantify the effect of this green system on the heating and cooling energy demands.The roof-lawn showed a high thermal inertia, with no overheating during summer, Services and a high insulating capacity, involving energy savings during winter, and consequently better indoor thermal conditions.
