The European Green Deal sets out a new growth strategy aimed at turning the European Union into a just and prosperous society, with a modern, resource-efficient, and competitive economy, which will no longer generate net greenhouse gas emissions by 2050. Cities in this context are committed on several fronts to rapid adaptation to improve their resilience capacity. The historic centre is the most vulnerable part of a city, with a reduced capacity for adaptation, but also the densest of values, which increase the complexity of the challenge. This study proposes an integrated tool, Heuristic Planning Support System (HPSS), aimed at exploring green-blue strategies for the historic centre. The tool is integrated with classic Planning Support System (PSS), a decision process conducted from the perspective of heuristic approach and Geographic Information System (GIS). It comprises modules for technical as...

Consequently, to achieve the objective of social sustainability, the rents of social housing must be below the market rents and low enough to be affordable. Italian law has set several rent thresholds which are based on local territorial agreements between landlords and renters associations. This article aims to examine whether these thresholds generate social fairness and housing affordability within each city and between different cities, or instead inequalities and spatial asymmetries. A cluster analysis is applied to study whether the goal of fairness is achieved, while the effectiveness of providing housing affordability is assessed by comparing the benchmarked rents with those of the national ministerial Real Estate Market Observatory. Two metropolitan cities—one in the north and another in the sou...

The renovation of existing hotels to achieve a nearly zero-energy (nZEBs) performance is one of the forefront goals of EU’s energy policy for 2050. The achievement of nZEBs target for hotels is necessary not only to comply with changing regulations and legislations, but also to foster competitiveness to secure new funding. Indeed, the nZEB hotel status allows for the reduction of operating costs and the increase of energy security, meeting the market and guests’ expectations. Actually, there is not a set national value of nZEBs for hotels to be attained, despite the fact that hotels are among the most energy-intensive buildings. This paper presents the case study of the energy retrofit of an existing historical hotel located in southern Italy (Syracuse) in order to achieve nZEBs status. Starting ...

In the prospect of investigating the relations between urban and life quality—corresponding to the “city effect”—in the territorial context of each of the 20 municipalities of the Enna district, a hierarchical descriptive-valuation model was created, which coordinates a relevant amount of information units (data) and the corresponding attributes, indicators and indices that have been turned in aggregate value judgments attributed to each administrative land unit, from the perspectives of the criteria referred to as the main forms of the territorial capital. This is a multi-dimensional valuation model based on the Multi-Attri...

The residual green urban areas are representative of a low level or absence of order, but above all, of functions and values. The study proposes a new methodological and operational approach to the rehabilitation of green residual urban areas, participatory type that can generate a new order between values, functions and actors, to mediate private and public needs, to promote new forms of responsibility and thus to implement some of the priority objectives set out in the 2030 Agenda. The operational tools supporting the approach are the Contingent Valuation Method (CVM), public and private partnership (PPP) and crowdfunding. This approach supported the selection of the project and the creation of a budget with public and private funding to support the participatory rehabilitation of a residual green urban area in the municipality of Acireale. The amount of fundi...

A co-effects-based policy approach proposes a multidimensionality capable of strengthening its effectiveness and supporting a co-generative development model aimed at promoting virtuous forms of territorial capital valorisation. The study aimed to evaluate the landscape co-benefits generated by the Natura 2000 networks, achieving a measure of efficiency of the policies and performance of the Management Plan, with reference to the “Timpa di Acireale” site. CVM and TCM were used for the estimation of landscape co-benefits. For the evaluation of the efficiency of the policies and the performance of the Plan, some economic-financial criteria were implemented. With reference to the user-citizen, the local tourist and the supralocal tourist, flows of annual co-benefits of EUR 754,764, EUR 99,678.12 and EUR 2,276.39, respectively, were esti...

It proposes a global economic-evaluative strategic planning pattern supporting decision-making in developing a specific energy-environmental equalization program. Starting from the huge database of the GIS describing the Architectural Units forming the old town’s urban fabric, the pattern features each of them with several architectural and energy attributes, so that each of them can be sorted among the different Categories of Intervention, ranging from the conservative to the transformative ones. Furthermore, the energy characteristics of all the AUs of the sample have been modelled in order to calculate the energy performance to be improved. The combination of architectural and energy characteristics provides the profile of each AU according to which the pattern associates to it the appropriate CI and calculates the related cost and real estate market price surplus to be used for the equalization. By releasing the constraint according to which an AU is sorted to a specific CI, the pattern is able to design several global strategies that can be ranked by performing a MAVT model.

This paper deals with one of the current public housing management policy initiatives, undertaken by the Municipality of Palermo (Italy), which aimed at transferring a significant part of the public housing asset to the current tenants, according to some terms and conditions, and applying a politically fixed price. This policy is described in general, focusing on the amount of the assets involved, reporting the terms and conditions for transferring them at an affordable price, and analysing their concentration/distribution in the urban areas. The main aim of the paper is to provide a valuation pattern for defining the trade-off between the efficiency and fairness of such a tool, recognising the conditions for the consistency between the transfer price establis...

Nevertheless, their more remote causes must be sought in the difficulty local and national communities experience implementing inter-temporal allocation policies. The consequent failures of the territorial policies trigger new inter/intra-generational disparities whose effects will eventually accumulate as causes of further entropy decay. The latter cannot be metabolized by the social system and remains an environmental trace. Due to pressing budget constraints, it is increasingly difficult to generalize proactive behaviors: this has an impact on the individual tendency towards temporal continuity, resulting in a further reduction of the resilience of urban territorial systems (cities and infrastructures) whose allocation policies are strongly imbalanced towards the present. The contribution focuses on the issue of intergenerational solidarity in the context of disaster prevention and management and therefore on the indicator of this solidarity, the social discount rate. Finally, it presents a summary of two case studies on floods and earthquakes.

Identifying these values for some of the possible configurations of components for a historic town centre is a complex task. This study proposes a cognitive, interpretive and evaluative model for the evaluation and choice of action in the redevelopment plan for a historic town centre, in order to locate amongst all possible redevelopment alternatives, those that best meet the prerequisites of sustainability. In particular, this study analyses the actions of the redevelopment plan for the Biancavilla’s historic town centre. The instrumental operational model for evaluation is of a multi-criteria type and in particular uses a MAUT approach. This multi-criteria approach allows for a ranking of the analysed alternatives on the basis of a set of criteria which take into account the sustainability of the interventions.

By referring to the case of the waterfront of Syracuse (Italy), this contribution introduces a semiotic-sociological pattern for accounting and assessment concerning the main topics of the Sustainable Development Plan currently in force. The assessment takes into account the connection of the multiple thematic layers grouping the different functional/symbolic land units that are characterised by a semantic link, within an assessment pattern working as a syntactic field, highlighting the interactions between them. The pattern involves the social relevance of the different criteria featuring this landscape unit by making the “facts of nature” and the “narrations of culture” worth together.

The management of the aqueducts is a strategic link in the sustainability chain; its mission is to contain the catabolic effects of dialectic between social system and environment, caused by inadequacies in the design, construction and maintenance of capillary networks in large part obsolete. Starting from some analyses of the criticalities of the infrastructure management, the contribution focuses on information as production factor, whose implementation may help resolve major problems, especially in the planning of interventions to improve efficiency of the underground pipelines network. With reference to the ATO of Caltanissetta, we estimate the positive economic impact that the implementation of ICT-based technologies have on the extension of the territory covered by the IWS, given the quality target.

The assessment was conducted to verify the economic balance and landscape sustainability of some of the most significant schemes submitted by nine teams entering a design competition organized by the Architecture Department of the University of Palermo. The assessment of the nine schemes focuses on the main issues of the territorial and real estate features involved in the regeneration process and connected with the large and polluted area surrounding the Petrochemical Industrial District of Syracuse. The analysis consists of two approaches: a Discounted Cash Flow Analysis and a Multi Attribute Value Theory pattern.

As a result, the evaluation process should integrate more approaches to quantify the different forms of capital involved. The seismic event can pose risks to an individual’s survival or reduce the quality of life. The assessment of the effects of the potential seismic vulnerability reduction plan on the population can be determined on the basis of the value of a statistical life (VSL). Among the possible approaches for its determination, that of the human capital (HC) was chosen for use. A critical review of the HC approach literature has been instrumental in defining an empirical approach t...

The study assumes an axiological approach to land planning, including a qualitative valuation model and an interactive multicriteria tool based on the combination of WebGIS and DRSA tools. The valuation model is based on an axiological pattern taking into account four groups of valorisations according to a semiotic marketing approach. A hierarchic three explains each of them, so that every land object or rail performance can be assessed into a general frame oriented to provide the aggregate value of the path that which they relate, as composed by the GIS network pattern aiming to meet the users’ preference profile. The DRSA tool allows generating the preferences structure of the target segments users.
