According to statistics, buildings and buildings construction sectors combined are responsible for 36% of global final energy consumption and nearly 40% of total direct and indirect CO2 emissions. As population on Earth grows, homes and other types of constructions are expected to multiply, in order to satisfy the needs for civilized life of every human being. Nowadays, most buildings receive the energy they need from external grids. Reversing this situation is viewed as a primary task in the struggle for naturally-compatible artificial environment. Borrowing from biomimicry, using plant skins as model and applying biophilic engineering principles, the building facades can be transformed into smart energy harvesting tool, which sustains the energy needs of the construction and allows more intensive interactions with the surrounding medium, providing adaptability as in the living species.
