An Integrated Decision Support System to Define the Best Scenario for the Adaptive Sustainable Re-Use of Cultural Heritage in Southern Italy

The objective of this document is to propose an integrated evaluation model to support the choice of an alternative of an historic industrial archeology building located in Southern Italy, in order to define a strategy shared based on a "bottom-up approach". The methodological path, in consideration of the needs of the local community and of the historic and cultural values of the historic building, is able to verify the feasibility and economic sustainability of the hypothesis in relation to different management models that involve different forms of public-private partnership. The positive results obtained show that the proposed model can be a useful decision support tool in contexts characterized by high complexity, where the goal is to build shared development strategies

Assessing the effectiveness of public investments in cultural built heritage: the case of the umbertine forts system in italy

The paper deals with the topic of the allocation of resources and investment strategies in cultural built heritage. The valorization of cultural assets is often guaranteed by the intervention of public funding. The need to allocate these funds efficiently and effectively, together with the transparency duties to which public administrations are subject, necessitates a careful measurement of the economic, cultural, environmental and social effects. Accordingly, the paper outlines the starting framework of a study on the ex-post evaluation of the effectiveness of public intervention towards the restoration and valorization of three forts in the Umbertine Forts System, located in the Metropolitan City of Reggio Calabria, southern Italy

A Pilot Plant for Energy Harvesting from Falling Water in Drainpipes. Technical and Economic Analysis

Renewable energy sources are currently object of great attention from the scientific community involved on the matter, in the general context of the ongoing climate change and related implications. In this work, we investigate the costs needed to implement a technical solution to harvest energy from drainpipes. To this aim, a pilot plant was built at the Laboratory of Environmental and Maritime Hydraulics (LIDAM), University of Salerno, Italy. The driving idea consists in the possibility of collecting rainwater at the roof of a building, storing it in tanks. In this way, the established hydraulic head can be converted into kinetic energy at the bottom of the building as can be easily explained by applying the Bernoulli’s principle. Here, a water jet of mean velocity of up to tens of m/s is formed at the pipe outlet as it is provided with a nozzle. The stream is directed against a Pelton turbine where the rotational kinetic energy is finally converted into electrical energy by means of a DC brushed motor turned as generator. The analysis of the investment and management costs of the pilot plant provides useful economic parameters for implementing the project in practice

I valori immobiliari urbani per l’interpretazione del caratteri socio economici della "Napoli de facto"

Secondo la disciplina estimativa, i valori di mercato degli immobili urbani dipendono dalle caratteristiche di localizzazione, riconducibili all’ambito territoriale di riferimento, e dalle peculiarità del singolo cespite. Le prime sono fortemente condizionate dalle politiche di pianificazione territoriale e dalla valenza tecnico-economica dei progetti d’investimento, a loro volta dipendenti da fattori sociodemografici e dalle disponibilità finanziarie che connotano l’ambito urbano. A partire dalla raccolta ed analisi di informazioni mercantili che attengono all’area vasta di Napoli, sono costruiti dataset ed elaborate rappresentazioni cartografiche dei valori patrimoniali secondo logiche GIS. Le mappe sono poi messe in correlazione con tavole predisposte su parametri socioeconomici in grado di incidere sui meccanismi di formazione del prezzo delle abitazioni residenziali. I risultati cui si perviene, nonché possibili sviluppi della ricerca, sono esposti nelle conclusioni del lavoro

Off-Site Construction. The Economic Analyses for the Energy Requalification of the Existing Buildings

The issue of energy efficiency in buildings is now of prime importance, both in terms of financial and environmental impacts. In this sense, the broad literature is expressed in agreement. The theme, which is certainly important for the entire construction sector, is analyzed here taking as a reference the off-site construction, sometimes little investigated in sector studies, both with regard to new buildings and with regard to existing prefabricated buildings. In the first case, in fact, new buildings must comply with the increasingly stringent energy standards that national and international regulations prescribe; in the second case, prefabricated constructions with low energy performance are widespread in many countries, for which efficiency measures are required. In both circumstances, however, the market is increasingly tempted to the problem, for reasons not only of housing comfort but also purely monetary, also attributable to the greater appreciation that a high energy performance has on the market. In this perspective, the paper first articulates the phases of an investigation protocol to be re-purposed in the definition of the interventions to be implemented for the energy efficiency of buildings. Subsequently, with specific reference to existing prefabricated buildings, it aims to select alternative processes capable of increasing the energy efficiency of vertical opaque structures. The preliminary technical selection of possible actions is followed by the necessary financial analysis. This, by comparing the investment and operating costs with the revenues generated by the savings on consumption, makes it possible to establish the best intervention option

Financial targets for the sponsee and the sponsor in the restoration/recovery of the historical and architectural heritage

The paper explores the theme of sponsorship for the restoration/recovery of the historical-architectural heritage. The goal is to propose a model that allows both the sponsee (often public institution) and the sponsor company (mainly private) to maximize the monetary return generated by the investment. The model is tested through the following case study: the sponsorship of the restoration works of the Don Tullio’s Fountain located in the Villa Comunale of Salerno (Italy). In the logic of the model, the funding requested by the sponsee is necessarily inclusive of the amount equal to the cost of the restoration work but should also consider the financial advantage deriving from the advertising return to the sponsor company. These targets are estimated through the direct audience critical variable connected with the number of visitors of the location of interest. For the sponsor, on the other hand, assuming a Cobb-Douglas production function, it’s possible to quantify under static conditions the optimal percentage of turnover to invest in sponsorship to maximize profits. Assuming, therefore, that several companies are interested in sponsoring the restoration of the monument, the application of the model makes it possible to determine which company would be most suitable to sign the sponsorship contract

The rational quantification of social housing - An operative research model

This work has addressed the issue of the urban redevelopment of brownfield sites. It has developed an evaluation model for the quantification of the social housing component that the private investor must make in favor of the public administration. The protocol is based on finding a balance between the interests of the parties involved in urban redevelopment. The algorithm is constructed by borrowing techniques from Operations Research Linear Programming. The objective function is to maximize the social housing quota. The constraints formalize the utility functions of the two contracting parties (public and private). The result is a simple to use mathematical process, which can be implemented in any local context, in order to make choices consistent with the potential of the local housing markets. The algorithm developed is applied to a case located in a municipality of the Agro-Nocerino-Sarnese (SA). The output returned enhances the rationality of the model, capable of contributing to the feasibility of the redevelopment of disused areas

Self-renovation in Rome: ex ante, in itinere and ex post evaluation

In Europe, self-construction/self-renovation are innovative and additional tools to meet the needs of a part of “disadvantaged” social groups that can not buy or rent dwelling at market prices. At the end of the 90 s of the twentieth century, the Municipality of Rome has set the first trial at the national level (still not completed and remained almost unique) related to disused building self-renovation (especially school buildings). The text shows the results of a research, still ongoing, aimed at ex post evaluation of items that have prevented to conclude timely and as provided such interventions and, consequently, doesn’t meet the housing needs for which had been started. This allows to highlight as the assessment tools, in the different phases of the development process of these initiatives, ex ante, ongoing and ex post may help to reduce the risks of “failure” of self-construction/self- renovation initiatives

Building Investments for the Revitalization of the Territory: A Multisectoral Model of Economic Analysis

Following the crisis generated by the financialization of private realestate, construction prices have gradually decreased depriving the housing market of the necessary growth stimuli. Many countries have set up measures to revive this highly strategic area for the national economy. With reference to the Campania Region Law n. 19 dated 28 December 2009, known Housing Plan, this work has two objectives: to recognize the fundamental estimation problems that need to be solved in the implementation of the Campania Housing Plan; in addition, predict the effects of the regulations on the regional economy, both in overall terms as well as for each production sector, with particular attention being given to the construction industry. Regarding the first objective, the contents of the law are analysed on the basis of the principles that govern the appraisal. The consequences of the Campania Housing Plan on the economic system are then evaluated using input-output matrices, which are able to capture the structural relationships that exist among the various productive sectors. The numerical calculations require a preliminary investigation aimed at collecting a list of interventions approved by local governments in accordance to the Housing Plan. The cost of the works, as proposed in the applications submitted to the local administrations, is the input data for the implementation of the Social Accounting Matrix 2010 of the Campania Region
