“…The most common aggregation operator is the weighted average function, which consists of the weighted average of the values provided by the attributes. Multi-attribute assessment models are often used for economic assessments in different areas, such as in the assessment of benefits arising from urban or environmental regeneration [21][22][23].…”

Reuse of Vernacular Architecture in Minor Alpine Settlements: A Multi-Attribute Model for Sustainability Appraisal

In the marginal areas of the Alps, there is a huge built heritage expressed by local communities, resulting in an architectural model that is sustainable in terms of its material use, resource exploitation, and landscape coherence. Although buildings in these small settlements have been largely protected from transformation, currently this heritage is largely underused. Thus, it is desirable to consider reuse and enhancement actions that can combine both economic viability and the protection of historic, cultural and architectural values. This paper presents a multi-attribute model for the evaluation of sustainability in reuse projects concerning traditional buildings in the Italian Alpine settlements. For the appraisal of sustainability, the model uses relevant parameters aggregated into three macro-indicators. The model was calibrated by an expert panel and tested on reuse projects in Sauris, in north-eastern Italy, where residential building type is characterized by specific techniques that are expressions of community traditions. The main results show that the attributes aggregation function is predominantly andness in all nodes. A short range in sustainability assessment is a predictable result, as the buildings used for the model’s application give a common judgment in some attributes. Finally, activities for widespread hospitality generate a greater expected return compared to commercial services.

“…The project under analysis involves the construction of five buildings. The design choices have led to the adoption of non-traditional technological solutions, such as the creation of green roofs, since these can offer benefits not only to the private individual, but also to the community [28,29] ( Figure 3). Buildings A, B, and C are for residential use and provide the following subdivision of houses in relation to the number of occupants, as shown in Table 2.…”

Social housing constitutes a partial response to the demand for affordable housing. In Europe, there are different forms of social housing, which are distinguishable based on whether they employ a universal or residual approach. The latter is employed by Italian initiatives for social residential construction, the financial instrument of which is the Investment Fund for Housing, a closed-end fund managed by CDP (Cassa Depositi e Prestiti) Investment, which provides public–private partnerships. The main obstacle to the supply of low-cost houses is the high cost of building areas or, in other words, the high urban land rent. The value of building areas is particularly high in urban areas and in widespread settlement areas, for instance, in Northeastern Italy. The main objective of this paper is to identify the trade-off between urban land rent and housing affordability in a social housing intervention in Pordenone (Northeastern Italy). Four different scenarios are developed, the variables of which are: Cost of the area (urban rent), cost of construction works (quality of the buildings), and household income distribution. The results show that achieving the economic and social objectives of a social housing investment simultaneously is not possible in any of the scenarios evaluated. To allow the social groups most in need to access affordable housing would require a reduction of approximately 30% of the estimated cost of a building area.

“…Other authors have demonstrated the profitability of this solution in non residential buildings [39,40]. Even the combination of solar panels with green roofs can be found in the study of Berto et al [41]. They produce energy that is an interesting alternative to achieve economic and environmental benefits.…”

Contribution of Roof Refurbishment to Urban Sustainability

Achieving sustainable urban environments is a challenging goal—especially in existing cities with high percentages of old and obsolete buildings. This work analyzes the contribution of roof refurbishment to sustainability, considering that most roofs are currently underused. Many potential benefits of refurbishment can be achieved, such as the improvement of the energy performance of the buildings and the use of a wasted space for increasing green areas or for social purposes. In order to estimate the degree of the improvement, a vulnerable area in Castellón (east Spain) was selected as a case study. A thorough analysis of the residential building stock was undertaken. Using georeferenced information from the Cadastral Office we classified them according to typology, year of construction and roof type. Some refurbishment solutions were proposed and their applicability to the actual buildings was analyzed under different criteria. The theoretical benefits obtained in the neighborhood such as energy and carbon emissions savings were evaluated, together with the increase of green areas. Moreover, other social uses were suggested for neglected urban spaces in the area. Finally, a more accurate analysis was performed combining different solutions in a specific building, according to its particular characteristics.
