Abstract

This paper comments on some technical aspects ofliving green façade systems, pointing out their advantages andconstraints. This environmentally sustainable strategy forbuilding construction and refurbishment is especially adequatefor South oriented facades, more suitable for plant growing,contributing to reduce heat island effect, lower emissions andeven a positive balance to buildings by absorbing CO2andliberating oxygen due to photosynthesis process. Green facadescan also reduce visual impact from buildings on landscape. Theuse and appreciation of native flora in these systems should bevalued. In this paper some examples of green facades arepresented and commented on their structural and functionalspecifications.
