The prices of the vertical greening systems analysed in this
study have significant differences (Table 2). The first option, direct
green façade, is made of climbing plants, which cost 22 V/linear
metre facade (H. helix); in this case, as well for indirect greening
systems (option 2Ae2B) a dig at the base of the façade is required
(requiring a cost of 520 V/linear metre facade). The supporting
systems made by HDPE and steel mesh cost respectively 36 and 94
V/m2 while installation costs 83 V/m2. For the indirect green façades
combined with planter boxes the costs are higher (Table 2);
besides these systems, as well as the living wall system (4), require
an irrigation system.
