—This study proposes extensive green roofs, based on three typologies, that in function of the resulting configuration are identified as modular, continuous and aerial. They all use herbaceous vegetation with premolded structures of light concrete, fabricated with a type of residue from the shoemaking industry, the Ethylene Vinyl Acetate (EVA). The typologies were designed and simulated, in real scale, in a laboratory, using medicinal plants. The modular typology uses vegetated blocks and corresponds to the simplest technique regarding installation and maintenance; the continuous typology is the system with vegetation and soil over plaques, providing the best plant development; the aerial type consists in the combination of vegetated blocks in two narrow bands of slab, with a screen between them, allowing the development of climbing plants, being this system the less biodiverse. All systems cater to the maximum weight parameter for extensive green roofs, and cater to the finalities expected from a green roof, with the possibility of having even additional contributions regarding thermal comfort, due to the use of a light aggregate in the composition of the premolded structures.
