A Multidimensional Assessment Model of Settlement Efficiency at the Urban Scale

Although the increasing ecological sensitivity has led to the diffusion of various protocols that allowfor the certification of the sustainability of a building or a district, tools currently used by planners for the multidimensional evaluation of urban planning projects on an urban scale are not yet available. The physical and functional organization of settlements is called upon to confront paradigms, principles and disciplinary criteria such as: contrast to land consume, urban compactness, density and multifunctionality, improving urban soil quality, adaptation to climate change. The aim of this contribution is to propose a multidimensional evaluation methodology that allows to control the level of urban efficiency of a settlement on an urban scale, through the identification of indicators that can be controlled from an urban planning point of view and can be used in the drafting of the implementation plans. The assessment of the degree of efficiency of a settlement, with reference to the presence of certain devices, is carried out by considering three different factors: resilience, resources, urban facilities. The methodology is configured as a support tool in implementation planning choices, allowing to guide urban planning towards higher performance values of settlements in terms not only of environmental but also economic and social sustainability.
