Green roofs: from greening to supporting biodiversity

(in french)

Many regulations now impose "green" roofs even for ever smaller areas. This change imposes technical constraints and precautions. Solutions exist that range from simple extensive greening to a real hanging garden, a support for activity but also for biodiversity.
Like the previous thematic evenings organized by the UPA-BUA, it will offer multiple and complementary approaches that will allow us to explore this topical issue.
