Pieces of stretched textile structure on which an inert substrate is installed. Thisinert substrate is covered with seeds, which germinate and grow on the textilestructure. This NBS can be fixed to the facades of the buildings on the street orby posts fixed to the sidewalk.

The green shady structures are built with:

• A waterproof layer formed by a PVC sheet. This layer is tensioned by asteel cable. The steel cable could be fixed to a façade or to a post. (In thefigure 28 the cable is fixed to the façades)
• Hydroponic substrate. Geotextile where the vegetation grows. Thisgeotextile is glued to PVC.
• Irrigation system located on the top of the PVC sheet. Irrigation systemlocated on the top of the PVC sheet. It is formed by drip irrigation pipesthat soak the substrate.
• Vegetation planted in seeds. The vegetation are plants with littlenutrient and water needs. They are species resistant to local climatesuitable for growing in an inert substrate such as geotextile.
• Water collection system. All the water from the irrigation system iscollected on the bottom of the garden.
• Public lighting
