green roof

The aim of this paper is to experimentally investigate and analyze the thermal and optical behavior of a Green Roof System (GRS) installed in the 10000 m2 roof of a fully insulated, bioclimatic office building in Peania. More specifically, during the experimental procedure, measurements of the outdoor temperature and relative humidity have been performed, as well as of the air temperature inside the building and the surface temperature of the ceiling.

The treatment of roof space with cool paint or vegetation is a widely employed urban heat mitigation strategy. As the allocation of roof space for social activity becomes more prevalent in the urban environment, there is a need to understand how cool roofs and green roofs can affect the outdoor thermal comfort of its users. 

Vegetation on the building envelope can have a marked effect on the microclimate and on the building’s energy behavior as well. In this paper, the impact of planted roofs on the thermal load of buildings is presented. Based on measurements and a series of
