Abstract: The wall or the frontage includes areas receiving plants and photovoltaic panels where the panels, arranged alternately with respect to the areas covered with plants, are cooled by an airflow circulating in contact with the plants, which allows operation of the photovoltaic panels under optimum conditions.

Abstract: A light self-supporting vegetated wall includes globally prismatic boxes, designed to be juxtaposed and/or stacked, the adjacent boxes being assembled together. Each box includes latticed or meshed surfaces, lined internally with a web, and filled with a cultivating substrate, such as humus. A network of water pipes and a network of air vents may be incorporated in the thickness of the structure, these networks passing through the parting lines between the boxes. The structure is designed for urban enhancement, as well as for producing noise screens, partition walls, hoardings and the like.

Abstract: The invention concerns a decorative device consisting of a support layer having some flexibility, on one surface of which are set and fixed, along predefined zones, plant or mineral materials of selected colours, which a produce a predetermined pattern. Said materials can be set using a moulding template, provided with orifices corresponding to said zones. Some raised parts left free on the support layer, advantageously surround the various coloured areas. The inventive device is useful for urban and landscape arrangement, as well as for decoration for special events.
