Figure 2: Stratigraphies of the experimental roofs compared to the green roof. The roofs, in pairs,
were different from each other in terms of the type of covering (copper or clay tiles) and the type of
under covering ventilation (ventilation absent, 3 or 6 cm air cavity)
In spring 2010 the covering module MNV_LR, facing south, was divided into two parts so
as to accommodate on one part (1.5 x 1.5 m) a green roof (Fig.3).
Figure 3: Some of the construction phases of the green roof on a module of the experimental
building: (a) installation of the drainage, storage and ventilation element, (b) installation of the soil
substrate,(c) planting of the “officinalis” vegetation
The type of green roof installed was the best for a slope of 17°. It was an extensive type
of covering having a culture substrate with medium – low thickness (15 cm) and with low
and evergreen vegetation of the “officinalis” type for which very little maintenance is
required. Fig. 4 shows the stratigraphy of the green roof that was installed while Table 1
shows in details the materials that constitute the roof.
