Sustainable building envelope - garden roof system performance

Garden roof systems (GRS) are specialized roofing systems that support vegetation growth on rooftops. GRS not only add aesthetic appeal to the unused roof space that is available in most urban areas; they also provide multiple benefits in an urban context. From a building's point of view, the plants and soil protect the roofing membrane from exposure to ultra violet radiation, extreme temperatures and physical damage, thus contributing positively to the roof's service life.Le syst\ue8me de terrasse-jardin (STJ) est un syst\ue8me de toiture sp\ue9cialis\ue9 qui favorise la croissance de v\ue9g\ue9tation sur les terrasses. Le STJ ne fait pas qu'ajouter \ue0 l'esth\ue9tique des nombreuses terrasses non utilis\ue9es des agglom\ue9rations; il leur apporte divers autres avantages dans un univers urbain. Les plantes et la terre v\ue9g\ue9tale prot\ue8gent le rev\ueatement des toitures des rayons ultraviolets, des temp\ue9ratures extr\ueames et d'une d\ue9t\ue9rioration physique, contribuant ainsi positivement \ue0 leur dur\ue9e de vie.Peer reviewed: YesNRC publication: Ye
