analisi lca (Life Cycle Assessment ) DELLE INFRASTRUTTURE PER IL VERDE URBANO

The growing awareness of the importance of greening within the urban areas is shown through the demand and the increasingly pressing need to develop a more livable and more sustainable model of city. This creates the need to streamline and make efficient the project issues of this resource, choosing, in the designing phase, material and technologies more sustainable. In this paper we compared, with the help of LCA method, the implementation of infrastructural systems, such as roads, curbs and barriers for urban green areas, in order to verify the choices that produce a lower environmental load. An examination of the different scenarios clarifies how some design choices, such as the replacement of concrete curbs or streets with bituminous, are certainly an improvement for environmental loads produced in a public green area. For other scenarios, such as the replacement of traditional fences with vegetable hedges, the results are not those desired, and indeed, on the basis of the end life time assigned to such arrangements, they are not advisable.
