Textile mills in Friuli (XIX-XX century). Building technique analysis and seismic refurbishment

The conservation of industrial architectures and the refurbishment project, must take into account the growing attention to the seismic risk of the built heritage, which the recent events of central Italy have made dramatically current. The different constructive nature and structural behavior of industrial buildings, impose a different approach, combining the new functional needs - and therefore the safety of the building - with its conservation as a testimony for future generations. The work focuses the Friulian textile industry buildings (XIX and XX century), studying their constructive techniques and identyfing some guidelines for the refurbishment

Insulating materials in Italian modern construction: techniques and experimentation in the colonies (1925-1940)

Italian colonial settlements (1870-1940) have provided the territories in which to experiment modern materials and construction techniques, in particular ready-built and standardized solutions, in African difficult climatic and logistic settings. This work focuses on the experimental employment of insulating (Eraclit, Cel-Bes) materials on light metal-frames in Italian colonies. Its object is to trace back the development of such construction techniques through case studies published in contemporary technical reviews and handbooks, underlining the mutual relationship between experimentation and industrialization, between theory and construction practice

Sauris residential building type. Analysis of typologic and constructive characters for a coherent rehabilitation intervention

3noThis research is focused on alpine building heritage in Sauris, a settlement in Carnia. Its residential building type is characterized by almost homogeneous spatial distribution and construction techniques, historically developed due to geographical isolation of this German speaking area and to availability of natural resource as wood, stone, soil and road-metal. To meet requirements for resettlement and Alpine tourism services, a methodology for rehabilitation is applied to Sauris building type. The proposed actions are compatible with original architectural characters and let a performance improvement in structural safety and energy consumption control.openopenStival, Carlo Antonio; Croatto, Giorgio; Valcovich, EdinoStival, CARLO ANTONIO; Croatto, Giorgio; Valcovich, Edin

Green Systems Integrated to the Building Envelope: Strategies and Technical Solution for the Italian Case

Green roofs and green and living walls are increasingly seen in cities, because they are an important strategy that addresses some key urban environmental issues and allows the achievement of different benefits. Among these, the most relevant ones are reduction of the \u201cUrban Heat Island\u201d effect, of rainfall contributions to the sewer system, of environmental impact and energy saving, and retention of harmful substance. The study aims to analyze different systems of greenery systems integrated (GSI), green roofs (GR), and green and living walls (GW-LW), as a possible retrofit technique of the envelope of heritage buildings and especially their applications in the context of historic cities in Italy, pointing out positive and negative aspects. Particularly, it pays attention to the green retrofitting of buildings and to the technical problems related to the installation of systems, since at the moment there are already several studies that show the environmental and microclimatic benefits of the integration of vegetation in architecture. This study tries to highlight the series of design procedures necessary both in the preliminary phase and then in the executive phase to relate the GSI to the existing building envelopes. The GR, from the results of the simulations conducted, demonstrate a greater simplicity in their construction, with improvements also from the point of view of the working loads on the existing structures, since the interventions are performed more easily than those on the facade. The study highlights the architectural needs that are not always considered such as the increase in the thickness of the roof and the related need to raise its edges, changing the perspective of the building. On the other hand, the GW and the LW show some complexity in their construction because they must deal with facades often rich in decorative elements and where openings aect the assemblage and connection works such as the tinsmiths of the intrados of the openings. It must be taken into consideration the necessity of having to drill masonry, often inhomogeneous, to connect fixings and the problems of stability this entails must be carefully analyzed

Nested-building as an effective strategy for the reuse of reinforced concrete industrial buildings. The case of the ex-Manifattura Tabacchi factory in Verona (1930-65)

[EN] Nested buildings today represent an efficient alternative to traditional recovery interventions in terms of cost-effectiveness, sustainability and compatibility with the existing building. The Italian territory has many disused industrial buildings on which it is necessary to operate with new recovery and re-market strategies. This article presents the results of the research, currently in progress, carried out by the ICEA department (University of Padua). The research concerns the recovery of industrial buildings in reinforced concrete from the 20th century. In these buildings the prefabrication allows a considerable optimization of the recovery interventions focused on modularity and prefabrication to fasten the construction times together with flexibility and reversibility. The analysis of the functional, structural and construction types made it possible to identify general intervention criteria which as the identification of the average span dimensions led to two design scenarios of wooden housing modules, following nested-building strategy. After a phase of study and critical analysis, criteria and guidelines for intervention were identified which as the identification of the average span dimensions led to two design scenarios of wooden housing modules, following nested-building strategy. The ex-Manifattura Tabacchi factory in Verona was chosen as a case study on which the results of the research were tested.Bertolazzi, A.; D'agnolo, E.; Fattori, G.; Piccinato, A.; Croatto, G.; Turrini, U.

Performance based building design to ensure building quality: from standardization to LEAN construction

The discipline of architectural design is influenced by the standardization activities concerning the construction and the development of tools for the coordination in the design process such as Building Information Modeling. The two disciplines contribute reciprocally to the achievement of the overall quality of the building process. To do so, it is strategic to develop researches on the following aspects: - definition of frameworks for the connection of the building system requirements to space and technology unit that defines it; - development of an inventory of interoperable and compliant technical solutions; - implementation of the discipline of model checking for project validation; and methodologies of comparison between intervention models; - implementation of collaborative environments for verification of compatibility between programs and regulations in order to identify the optimal design solution

Up-one: problems issuing from upward extensions of 1950-1900 residential buildings

Though presenting typological and construction-related features different from other European countries, Italian residential buildings as a whole fail to meet the performances required by the European Union before the 2050 deadline. Among the hypotheses meant to upgrade residential buildings, adding floors is regarded as capable of meeting the demand for new lodgings without any further soil consumption as well as of being the driving force leading to the overall upgrading of the building. The research has been aimed at focusing on the problems arising from upward extensions within the Italian seismic context, by means of digital environment surveys, defining intervention guidelines that can be applied to adding floors to 1950-2000 buildings

Architettura, tradizione e recupero in un centro storico minore del Friuli Venezia Giulia

We propose the result of a prolonged research work developed, relating to traditional vernacular architectures characterizing minor contexts. The focus of the contribution concerns in particular the territorial area of Valcellina (Pn) characterized by historical and environmental specificities. From a common elementary typological matrix attributable to the paradigm of the pre-Alpine house, the building heritage has evolved into a series of variants that have determined its progressive adaptation to economic and environmental conditions. From a common elementary typological matrix attributable to the paradigm of the pre-Alpine house, the building heritage has evolved into a series of variants that have determined its progressive adaptation to economic and environmental conditions. In the smaller centers scattered along the valley the aggregation processes of the primitive bicellular units are readable, with redefinition of the vertical connection paths, of subdivision into single-cell units (columnar houses at Andreis), of progressive closure of the balconies with the generation of a subsequent type (loggia house) most present, above all for climatic reasons in the upper part of the valley, but with different connotations than the similar constructions of nearby Carnia. The study clearly shows how the spontaneous conscience of the settled population is reflected in the constructive culture and as a consequence this remains with the changing environmental contexts
