Over the past two decades the Council of Europe has addressed cultural heritage preservation policies to the use of heritage as cultural capital. Given this definition, the conservation of cultural capital is crucial, for its intrinsic value and as an investment for cultural, social and economic development. Thus, principles and areas of actions have been defined with the aim of underlying the importance of cultural values for territorial identity. Especially for cultural heritage with a potential for tourism, the decisions about valorization interventions are not always consensual, given the coexistence of different instances from local inhabitants and tourists. Selecting among the potential uses the one that could ensure the preservation of physical characters as well as intangible values, fueling economic development, is still a challenging policy and design issue. In this context, this paper proposes the use of a multi-methodological approach based on Choice Experiments and Social Multicriteria Evaluation to support the adaptive reuse on real case study. The NAIADE approach has allowed the decision maker to consider both socio-economic and technical dimensions within the same evaluation framework.

The National Strategy for Inner Areas (SNAI) is a public policy designed to tackle depopulation in inner areas, defined according to the distance from centers offering essential services. Such a policy’s success is crucial to address the new challenges for planning brought to light by the COVID-19 pandemic. In this sense, there is a need to adequately support its implementation by providing handy decision support tools, understanding the power balances among municipalities, and defining proper interventions. The Indicator Grid, already used by the SNAI for project areas selection, can answer this need. However, the Grid’s application to support public policy at the municipality level requires reviewing some of its features, such as the indicators’ large number and the impossibility of defining some of them at the municipal scale. Based on these premises, this paper aims at supporting inner areas policies by carrying out a critical analysis of the current SNAI Grid, aimed at improving its effectiveness. It relies on a hybrid methodology that merges qualitative data interpretations and statistical analyses. Thanks to this method, defining a parsimonious Grid by leaving its complexity and information level untouched is possible. The so-defined set of indicators can represent a valuable reference tool in pinpointing priorities for actions or selecting further territorial scopes from the SNAI perspective, even if it still brings some criticalities to be faced.

In Italy, the Legislative Decree 49/2010, issued according to the European Directive 2007/60/EC, introduced the Flood Risk Management Plans (PGRA) as a mandatory requirement for the flood-risk areas to reduce the impact of flooding on human health, environment, cultural heritage and economic activities. The PGRA plays a crucial role for the prevention and sustainable planning for risk areas, through the identification and evaluation of appropriate interventions, in contrast to the traditional approach based on emergency actions. Starting from the analysis of the PGRA requirements and contents, this paper aims to highlight the role of evaluation with respect to the plans implementation and the multidimensional issues emerging when laws and standards are applied. Many evaluation issues are still open, such as: (i) the uncertainty due to the long-term perspective generally used within this kind of investment decision; (ii) the estimation of the complex social impact of vulnerable areas; and (iii) the definition of a social discount rate able to reflect the intertemporal preferences of today’s generation over future ones.

Composite indicators have been analyzed by several scholars, especially with the aim of defining standardization and aggregation rules consistent to the multidimensional theoretical framework underlying these kind of measures and adequate to the difficulty of comparing data of different nature. Starting from a broadly shared methodology, set up by OECD in 2008, the paper proposes a Composite Indicator of Territorial Vulnerability based on environmental, social and economic criteria. A special attention has been paid to the methodological approach more than to the results, with a focus on uncertainty and sensitivity analysis. The latter one has been developed by the use of the SimLab (http://ipsc.jrc.ec.europa.eu), which has allowed to estimate the probability distribution function of the composite indicator and to point out the field of variation of its variables. Lombardy Region has been selected as a pilot case study since it is one of the Italian regions with the highest infrastructural development. The results show that the Composite Indicator of Territorial Vulnerability applied to municipalities in the Lombardy Region has a limited variation range, and thus low uncertainty. Furthermore, the synthetic measure of territorial vulnerability seems to be a promising decision aid tool in the field of regional infrastructural development policies.

The paper is aimed at exploring the advantages of public authorities within the context of negotiating Public Private Partnership (PPP). During recent years, many European cities have developed complex urban interventions through innovative forms of cooperation between the public and private sector. Given the limited public funds to cover investments and the need to increase the quality and efficiency of public services, this kind of PPP enables public and private sectors to define agreements with respect to future urban development interventions. Starting from an analysis of the urban developments under PPP carried out in Lombardy region over the last 15 years, the paper provides an overview of surplus values that result from land-use changes and development with the aim of pointing out the allocation between public and private parties. Despite the difficulty of performing an ex-post evaluation of surplus values, meaning the difference between the asset values before and after transformation, mainly for the limited and incomplete economic data recorded by the agreement, some preliminary insights are drawn, and a first operational framework is suggested to evaluate the sustainability of the urban development interventions from a public perspective.

Multiple factors influence individuals' health status. Their impact is difficult to quantify as it is their interaction. Aim of the current work is to develop guidelines to support designers to promote health in the residential environment and to apply them through an evaluation system to certify the level of health performance.Politecnico di Milano, in collaboration with the Local Health Authorities of Milan and Empoli through analysis of needs performance and numerous multidisciplinary meetings, has produced a design guide (Healthy Design Guide - HeDe) and an evaluation system to certify the level of health performance. This system was tested on the Milan metropolitan area.The experiment was carried out on a sample of 30 private residences, with an overall floor area ranging between 90 and 150 square meters, new or recently renovated.The tool works but at the same time it also shows that too often design choices are made for aesthetic or economic reasons rather than a real need for health and wellness.It is becoming increasingly important to strengthen synergies and multidisciplinary collaborations to achieve shared performance indications and to make a systematic review of the regulatory tools to protect public health.

In the last decades, the growing concern about land consumption, together with the awareness about cultural heritage’s key role for sustainable development, has led to greater attention to cultural property reuse as a conscious process of new values production. However, decisions about heritage bring a high degree of complexity, related to the need to preserve properties’ values and fulfill protection legislation, thus bringing high cost, which discourages public and private investments for reuse interventions. In this context, it becomes urgent to support reuse decisions through proper evaluation methodologies that, dealing with the complexity of interests at stake, allow individuals to assess the financial sustainability of conscious cultural heritage reuse projects. For these reasons, the paper proposes a methodological framework that, grounded on the recognition of cultural properties’ values and their possible integration in the local economic system, assesses reuse projects’ financial sustainability. This methodology’s application is discussed through a case study, represented by a project for a historical rural landscape in Pantelleria island. The application to the case study allows us to discuss the role of the proposed evaluation framework in supporting and promoting cultural heritage reuse and its possible room for improvement.

In recent years adaptive reuse has proven to be a promising strategy for preserving cultural heritage. When the adaptive reuse approach is used for cultural heritage, the expected outcome is not only the building protection, but the preservation of its historical and heritage significance, and the trade-off between the retention of symbolic values and the adaptation to new alternative (economically profitable) uses becomes of paramount importance. Decisions on the allocation of resources for cultural heritage preservation or development are based on a set of multiple, often conflicting, criteria, as well on the preferences of various, and not always consensual, stakeholders, who attribute different relative importance to market and non-market effects of adaptive reuse proposals. In this context, multiple criteria approaches provide a proper theoretical and methodological framework to address the complexity which characterizes adaptive reuse strategies of cultural heritage. This paper aims to contribute to this strand of literature by proposing a multicriteria decision aiding approach for ranking adaptive reuse strategies of cultural heritage. In detail, we present a novel application of the Preference Ranking Organization Method for Enrichment of Evaluations (PROMETHEE) to support the design and implementation of adaptive reuse strategies of abandoned industrial heritage in vulnerable contexts, and evaluate relative tangible and intangible effects. Industrial sites are frequently left to deteriorate, as their preservation is not considered as important as other kinds of heritage structures. Nevertheless, they are characterized by special architectural and technical features as well as by huge spaces suitable to be redeveloped for new uses. The paper focuses on the potential reuse of nine different abandoned buildings located in an industrial valley in the North-West of Italy, with a strong presence of wool and silk factories starting from the 18th century.
