Nowadays, energy equalization is one of the many issues concerning the energy policies on the urban scale and in the perspective of reducing the Urban Heat Island effects (UHI-e). The different economic-financial profiles of the interventions implemented in the buildings having a wide range of climatic locations, typological arrangements, architectural-historical constraints, need to be coordinated within unitary local energy-environmental policies inspired by economic-financial as well as environmental issues. The renovation of existing hotels to achieve a nearly Zero-Energy performance is one of the goals of the 2050 EU’s energy policy. This paper presents the nZEB retrofit case of an existing historic hotel and proposes a step by step approach to nZEB performance with a perspective on the costs, in order to identify the most effective energy solutions. Such approach allows highlighting useful insights regarding energy and economic-financial strategies for achieving nZEB standards.

The European Green Deal proposes an epochal change in the European society by transforming environmental and climatic problems into opportunities and making sustainable and fair the European Union economic system. Radical changes will also concern urban redevelopment and energy efficiency measures in order to reduce global greenhouse gas emissions. To achieve these objectives, rules and standards, as well as financial resources and assessment tools, are needed to support both urban planning and public decision process. This paper aims to analyze the existing European programs that are applied in some European smart cities, as they constitute a valuable source of information for the development of financial schemes and evaluation tools ad hoc for the Green Deal implementation. Moreover, the analysis of the pilot projects of the ZenN program has made possible to identify some critical issues regarding the economic feasibility of energy retrofit at a district scale, though further studies will be required to respond to the new assessment challenges launched by the Green Deal.

The phenomenon of the “houses for one Euro” is the epitome of the progressive and increasing abandonment of the inland territories in which many small towns are affected by continuous and unstoppable depopulation. This process, mostly affecting the southern and insular Italian regions, have been triggered by the quick industrial development started after the second post-war, led by the northern regions, that deeply and irreversibly modified the anthropography of the whole country until now. The impoverishment of a wide part of the Italian territory, is one of the many issues connected to the social-territorial justice that is the original topic by which appraisal and valuation, that is science of the economic value judgement, differs from other branches of the applied economics. With the prospect of an insight of the case of Calabria, the paper presents: as first some factual basic premises for defining the matters and the sense of the concept of land debt; as second some theoretical and methodological coordinates for reinterpreting “abandonment as a metaphor of being back”.

As many low-income households have still been facing the problem of affordable housing, in several countries governmental institutions have implemented various measures of housing policy and are supporting both the “right to housing” and the “right to buy” a dwelling at a subsidized price. Alienation of public housing is a political measure mostly directed towards low-income tenants, by which the dwellings are sold at a price set by law, assumed as a “administered” price. The gap between market and administered prices may be considered as the “value of solidarity” to be taken into account as the monetary reference of the social housing welfare policies aimed at reducing social inequities. The solidarity value approach has been implemented here to identify some measurements of the overall management efficiency (concerning the allocation of the public housing asset) and the social equity between the tenants whose “right to buy” should be fostered. The management efficiency concerns the ratio between the “administered price”, fixed according to the regulations in force, and the potential property market price; the social equity concerns the homogeneity of the prices registered over the actual transfers. The model is applied to a case study in the city of Palermo (southern Italy), where the Municipality implemented an ‘Alienation and Real Estate Development Plan’.

The challenge of promoting sustainable cities and reaching the objectives developed by the European Green Deal includes the renovation of the building sector, as it is responsible for 40% of energy consumption in Europe. Regional or local public administrations have to allocate their financial resources for improving the energy performances of their building stock and to face a multidimensional problem, where different aspects – such as energy efficiency, financial-economic feasibility and environmental protection – have to be harmonized. The present study proposes a Multiple Criteria Decision Aiding model, which includes the ELECTRE TRI-nC method, for supporting the public decision process of sorting alternative energy retrofitting actions into various categories, each of them expresses different levels of overall performance. The model is applied to an Italian real case study. An experts’ panel has been involved for structuring the decision problem and discussing the results. The results show that opaque envelope insulation actions are often classified in best categories to be implemented and funded instead the upgrade of the lighting system falls in the worst category. These results are useful for local or regional public administrations to select those energy retrofitting actions that have to be financed as a priority.

Archaeological sites are part of the history and identity of a community playing a strategic role on the different scales of the cultural and economic common life. Whereas on the one end the most famous archaeological sites attract huge flows of tourists and investment, on the other hand, many minor archaeological sites remain almost ignored and neglected. This study proposes a project-evaluation approach devoted to the “minor” archaeological site development, outlining a territorial, socio-economic, and landscape communication pattern aimed at creating an archaeological network integrating other cultural and natural resources. As such, these networks get able to match the demand of customers who shy away from iper-consumerist tourism and want to deepen their knowledge of a place. The proposed approach integrates knowledge, evaluation, and design in a multiscale pattern whose scope is to foster and extend the archaeological research program, involving public and private stake/stockholders to widen the cultural-contemplative experience and promote further educational events concerning the themes of the local identity. With reference to the archaeological basin of Tornambè, Italy, a Web-GIS knowledge system has been drawn to provide the territorial information requested by the economic-evaluation multiscale pattern implemented to verify the cost-effectiveness of the project. The expected negative results of the economic valuation supported the allocation pattern of the considerable investment costs, as well as the hypothetic scenarios about the evolution of the cultural-contemplative experience due to the extension of the archaeological estate. Some disciplinary remarks propose a heterodox approach for a further interpretation of the economic results and financial indexes, by introducing the monetary dimension of such a social capital asset.

An urban park provides many environmental and recreational facilities and services, and moreover it may become a catalyst for social energies and an instrument of community identification. This paper analyses whether participation and bottom-up planning may compensate institutional absences in implementation of urban parks, and how multiple criteria model may support socially shared decisions about their management. These issues are examined from the singular case of Parco Uditore in Palermo (Italy) that is located in a land which has been surprisingly undeveloped, despite the expansion of the city. The phases of promotion, planning and implementation of the park were the result of a synergistic but spontaneous collaboration of multiple actors, whereas an Analytic Network Process model has been built in the current management phase. The model has been provided for supporting a structured participatory process between promoters-managers and users for the selection of the best project among several alternatives, in order to strengthen the environmental, recreational and social role of the park.

This paper aims to examine the theme of energy retrofit within the circumscribed field of refurbishment interventions on load-bearing masonry buildings built in the early 20th century. These include a remarkable share of the fabric of many European cities and, in particular, they can be found in geographical areas characterized by a Mediterranean (mild) climate. The main objective is to increase the climate resilience of the buildings by verifying the economic feasibility and the environmental sustainability of the interventions, and moreover by observing the specific architectural features of the buildings. We put forward alternative retrofit solutions carrying out synoptic comparisons of several technological solutions and types of materials, assisted by the use of digital tools such as BIM. In order to increase the environmental compatibility of the intervention, this article carries out a closer examination of the comparison between the employment of nanostructured, conventional—of synthetic origin- and natural materials. The selection of the best intervention solution required the elaboration of an iterative flexible integrated process of assessment of energy, technological, economic, environmental and architectural aspects. The methodology we propose here is applied to the case study of Palazzo Utveggio (Palermo, Italy).

Public housing policy has been proposing plans of public housing (PH) stock alienation or, as an alternative, property enhancement plans, since administrative and financial commitments have become too heavy for municipalities. 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 established by municipality, the merit of the public housing asset, and the market value. A detailed study on two representative neighbourhoods was carried out in order to measure the value of solidarity of this policy and to propose some corrective rules.

The “challenge of complexity” is one of the many points of convergence between the Encyclical Laudato si’ and the evolution of post-modern scientific thought. This study aims to analyze how complexity represents the essential element of the profound renewal in the scientific paradigm of the discipline of evaluation, particularly in regard to the theory of value, the categories of value, and the instruments of multi-criteria evaluation. Some contemporary theories of value propose, in fact, a complex source of value, such as surpluses of energy and of information (Ecological Economics) or as the creative and synergistic combination of three surpluses, namely energetic and non-entropic, genealogical-ecological, and scientific-cultural (the “Nuova Economia” of Francesco Rizzo). These theories derive from a new interpretative key founded on the alliance between the natural sciences and the humanities. The creation of new categories of value, the social use value and the total economic value, constitute, moreover, the response of the science of evaluation to the social and disciplinary need to express a complex value that goes beyond both the private use value and the (normal and speculative) exchange value, and which include the multiplicity of values (ethical, aesthetic, economic, cultural, scientific, political, juridical, and equitable) that express the human being as a whole, no longer reduced merely to the homo economicus. The demand for the resolution of complex problems involving public and private territorial assets has led to the elaboration of models of multi-criteria evaluation through which to recompose the conflicting dualities of equity/efficiency, quality/quantity, and local/global into a uni-duality. In these models, the absence of a monetary unit of measurement constitutes an opportunity for re-founding a system of common social values and for allowing the participation of local communities in decision-making processes (Bentivegna 2016). The evaluation discipline, furthermore, may continue to participate directly in the great cultural, spiritual, and educational challenges contained in the Encyclical, to change the style of life and the patterns of production and consumption, making its own contribution in three spheres: scientific-cultural, through studies and research orientated towards the promotion of the culture of complexity, of multidisciplinarity, and of environmental protection; social-territorial, through collaboration with public institutions to elaborate operative instruments (models) of social participation in local decision-making processes; and educational, through the qualification and training of architects and engineers.

The landscape units of the Sicilian mountainous inland, as for the case of Petralia Soprana, are marked by the presence of ancient urban centres controlling the agricultural territory, from which they derived their own wealth, and to which they conferred landscape significance. The unity between economy and landscape has been interrupted by the radical transformation of the socio-economic structure and the technologic progress, which have eroded the consistency between structures and superstructures. We propose an assessment approach based on a synthesis of semiotic and phenomenological view. The approach mainly focuses on the basic concepts and contents of the valuation process that can be assumed as the theoretical premise for the operational tool.

When urban and environmental transformations occur in areas where the equilibrium between nature and culture is complex and fragile, public administrations could decide to induce private investments using several tools, such as financial contributions to those projects of refurbishment that better respect the purpose of improving the environmental quality and of preserving the local architecture. Multicriteria models may support public decision process regarding this issue, but it is essential to adopt a scientific paradigm that provides a major theoretical reference. This study proposes the development of a network model based on the scientific paradigm by Rizzo and the Analytic Network Process. The first one has been chosen because of its interpretation of the city as autopoietic organization, dissipative structure and political-administrative system, the second one because of its holistic representation of the decision problem in which the interactions between all the elements are made explicit. The network model has been applied to a case study that consists in ranking some alternative refurbishments of buildings in Favignana (Egadi islands, Italy) in order to grant public financial contributions.

Housing affordability problems have become more serious over the course of the last few decades and are now also affecting the middle-class, despite the fall in prices on the housing market. This study proposes a methodology to assess threshold-income as an index for measuring housing affordability by applying a combination of the ratio income and residual income approaches. The methodology is applied to two particular areas of Sicily in Italy as case studies consisting of medium-size metropolitan areas located in a less developed European region. The areas have been chosen on the basis of their different territorial structure: a polarized area that comprises a high-density city centre and a polynuclear urban region. The results are diversified for income level, as well as for town and urban zone, and allow us to compare the housing affordability problems between towns belonging to the same metropolitan area.

Real estate capital is in constant competition with other capital assets due to its different and complementary economic functions such as direct use, productive investment, and speculative investment. These features and the resulting opportunities cannot be easily deduced from direct observation of the real estate markets, so some further insights need to be carried out in order to highlight the relationship between prices, rents and performances. This study aims at providing a multifaceted perspective of a specific urban real estate market to overcome the difficulties arising from opacities and informative asymmetries that hinder the decision of investors, by facilitating the comparison of different options such as capital value, income and performance. Within the mass appraisal approach, the study proposes a methodology for the analysis of the cap rate, intended as the expression of profitability and liquidity of the urban real estate capital asset. The methodology is based on a detailed survey of a sample of the housing market data, collected within a structured database, supported by statistical and territorial analyses of the sample, in order to display the range of cap rates featuring each sub-market, and the related distributions. The methodology is applied to a case study of nearly 1000 properties distributed in a vast urban area of the municipality of Palermo, Italy. The consistency of the relationships between the three variables has been tested with reference to two hypotheses about the sub-market definition, which has been carried out by cluster and by neighbourhood.

The analysis of the housing market of a city requires suitable approaches and tools, such as data mining models, to represent its complexity which derives on many elements, e.g. the type of capital asset-house is a common good and an investment good as well, the heterogeneity of the urban areas—each of them has own historical and representative values and different urban functions—and the variability of building quality. The housing market of the most densely populated area of Palermo (Italy), corresponding to ten districts, is analyzed to verify the degree of its inner homogeneity and the relations between the quality of the characteristics and the price of the properties. Five hundred sets of housing data have been collected and elaborated by cluster analysis with the aim of describing the structure of the housing market in each district and developing operational tools for the implementation of urban policies and public-private investments.

The implementation process of the Syracuse's Master Plan is characterized by the widespread use of “urban negotiation”. The Municipality has drawn up a protocol aimed at obtaining areas for facilities and public infrastructure in different areas basing on the rule of the transfer of a portion of land in return for the building permission for the remaining part. Since these areas are variously characterized, the negotiation process may not be fair to Municipality or convenient to land owners. Basing on an equalization pattern, this study provides, for each area, the indexes of fairness and convenience, and, more specifically, the difference between the market value of the areas achieved and the value of the permits issued. and based on the possibility to transfer the development rights, some different scenarios are prefigured about the possibility of acquiring additional areas for social housing and/or achieving funds for sustainable buildings.

The issue of affordable housing has again become crucial in ensuring a greater social equity, increasing social cohesion and reducing inequalities within metropolitan or regional systems which, in the current climate of severe economic crisis, have to respond to global challenges of development, innovation and sustainability. This study aims at building a system of knowledge about the housing affordability on the territorial scale, by which to identify the local characteristics of housing problems that could be solved through traditional planning tools or new practices of social housing, which involves private stakeholders and/or public administrations. This system of knowledge should include the analysis of the wealth distribution both in terms of income and real estate market price, and the calculation of the income-thresholds (based on the HAI-Housing Affordability Index) that filter the access to the real estate market. All these data are used to define the correspondences between groups of people and affordable housings, distinguishing them both by income and urban location. This approach is applied to the case study of the territorial system of the Province of Syracuse (Italy) and it allows appraising the gap between housing prices and income level in different areas of seven towns. To know the size and the spatial distribution of these gaps is a valuable tool to orientate the housing policy, to select the best model of social housing and to design the equitable parameters of social housing projects for each town.
