Capella Garcia Arquitectura are the creators of the Green Side-Wall vertical garden on a façade in Barcelona, representing “the birth of a novel type of construction in the field of vegitecture.”
Consisting in a free-standing structure parallel to the façade of a building, the green façade continually changes, cooling in the summer and insulation in winter. Generating oxygen and absorbing CO2, it filters dust and forms an acoustic screen that reduces noise.
"The free-standing structure is inspired by the form of a tree. For maintenance of the vegetation that forms the façade, all requirements for cleaning, safety and sustainability have been accounted for. Water consumption is minimised by means of an automatic irrigation system."
