The economic effect induced by the presence of green has been estimated by determining the increased building value and therefore
the consequent increase of rental income. For this type of property (office building), in fact, the rental market (and not the
sale market) is more significant and therefore an attention to aesthetic and functional qualities due to green may increase the
rental income. For the estimation of the average values, the rents listed by the OMI (Real Estate Market Watch e Agency Land e
Provincial Bureau of Genoa) in the second half of 2012 for commercial property (offices) located within the three selected real
estate areas are used [36]. Increases in annual fees are taken into consideration in CBA models starting from the year in which plants
will fully cover the façade. The increases in annual rent related to the specific locations assumed in this study vary from 1960 to 3550 (V/m2/year).
