Moss as a multifunctional material for technological greenery systems

Nature-based solutions can help mitigate the heat island phenomenon in densely populated urban areas. As far as building envelopes are concerned, both green roofs and walls provide multiple benefits to the surrounding areas and to the buildings where they have been installed by using plants that act as building materials with specific attributes and performances. In detail, living wall systems are particularly sensitive to the vegetal choice due to their sophisticated technology and to the artificial vertical layer where plants are forced to live. The purpose of this paper is to investigate the characteristics of mosses in relation to their potential use in technological greenery systems. In this regard, the most recent and innovative application examples in buildings and design are presented and discussed.
