A high thermal resistance and air tightness of the building envelope risk to create great internal moisture load with consequences for durability of materials and inhabitants’ comfort and health. The passive solution here proposed is a moisture buffering “active” device (MB-AD), to be integrated in the building envelope, which is able to measure the RH indoors and react by increasing the MB ability of a material forcing the passage of air inside it. The hygrothermal performance of the device has been experimentally tested and results showed that the Moisture Buffering Value measured in the “active” device increased until 29% more than the “passive” one.

Authors: Serpelloni Anna , Gialanella Stefano , Albatici Rossano
Published: June 2022

The Cradle to Cradle (C2C) approach is based on the eco-efficiency in accordance with strategies of expansion, up-cycling and enhancement of products both in environmental and social terms. Being this method currently under development, it has been mainly tested in the industrial production cycle, while in the building sector clear guidelines for the application and exhaustive reference cases are still lacking. This paper presents and discusses the application of the C2C methodology to a test building, designed for research purposes, the ZEFiRe - Zero-Energy Fishfarming Research module.
Experimental and numerical assessment of breathing walls performance for theimprovement of air quality and comfort indoors
Authors: Di Giuseppe Elisa , D’Orazio Marco
Published: June 2022

The construction of airtight building envelopes within nearly Zero Energy Buildings is likely to generate thermo-hygrometric discomfort indoors, that needs to be managed with airconditioning and ventilation systems. In countertrend, some researches developed in northern Europe countries focused on the construction of “breathing” building envelopes that let in the air (passively or with mechanical devices) through dynamic thermal insulations able to preheat and filter it from possible pollutants. This study reports the results of experimental and analytical assessments of dynamic insulation systems, aimed to the design of a breathing wall system for the application in building renovation interventions.

Improving human safety in cultural heritage buildings: experiments on effectiveness of wayfinding systems in a theatre
Authors: Quagliarini Enrico , Bernardini Gabriele , D’Orazio Marco
Published: June 2022

Current fire safety regulations in historical buildings are generally limited to the number and dimension of exits and evacuation paths. This approach clearly clashes with preservation criteria because of the need of invasive layout modifications. On the contrary, a “behavioural design” approach could solve this conflict by proposing evacuation facilities based on effective human behaviours. This work proposes an innovative wayfinding system based on phtoluminescent continuous signs. Experiments in a significant real world scenario demonstrate the possibility to considerably decrease the evacuation timing without building layout modifications.
New materials and technologies in in architectural heritage restoration: masonry columns confinement using basalt fibres ropes
Authors: Greco Federica , Lenci Stefano , Monni Francesco , Quagliarini Enrico
Published: June 2022

This paper deals with strengthening and consolidation of masonry columns, a long developed issue that also in the past interested restorers and designers in their works. A typical past solution for solving this kind of problem involves the use of a jacketing of the column by metal profiles. Nowadays strips of composite materials have been substituting these last ones but, when it is wanted to maintain the original aspect of the brickwork, this technique cannot be applied, so an experimental campaign about consolidation of masonry columns using a flexible element located in mortar joints has been developed. The results show the effective of this innovative technique in enhancing compressive strength of masonry columns without compromising their aesthetical appearance.
Agro-Urban contact. Comparison between long lasting organisms and foundation villages
Authors: Perra Aurora
Published: June 2022

Among the characters that characterize the relationships between agro and urban you place the exploration theme of the urban-function in relation to the rural context. Emerges the comparison between techniques-approaches belonging to the tradition, and those relating to the time of the reclamations where, technique and progress aim at the radical transformation of the processes of construction of places and building organisms, of settlements and agro fabrics. The objective of the research is to investigate the criteria for comparison within the scope of rural landscapes using as case studies San Vito and San Priamo, in Sardinia; identify resources and quality, which could serve as a reference rule for a future declination of contemporary construction methods in agro-contact function
Architecture in iron in the city of XIX century Roof structures of theatres and covered markets in Palermo
Authors: Fatta Giovanni , Campisi Tiziana , Vinci Calogero
Published: June 2022

In post-unification Palermo, components manufactured abroad were usually used for complementary iron structures (greenhouses and skylights, projecting roofs, staircases…), whereas, for more demanding works, more weight was given to the contribution of producers with experience gained in the field of metal construction. Analysis is here carried out on the works of greatest importance, from the roofs of the two major theatres to the roofing of food market structures; the finest technicians were employed and a critical debate was triggered in the city with regard to formal, static and building aspects.
“The design of a system”. Industrialized schools in Italy (1960-1975)
Authors: Giannetti Ilaria
Published: June 2022

The historical reconstruction shows how the industrialization of the schools building sector, was developed in Italy far from the corresponding European experiences. In fact, although the school building sector represented in Italy the most actual tender to stage a general process of industrialization of the construction process (for temporal extension and scale of production), the fragmentation of the planning horizon forces the outcomes on a small-scale production. The industrialization of building systems was, thus, deeply related to the single realization (or a small group of buildings). Today, this fact underlines the need to deal “case by case” (through the knowledge of facts and buildings) the actions due to preserve the buildings heritage.

Analysis and control of façade claddings structural issues
Authors: Sergio Mazzucchelli Enrico , Angelo Lucchini , Tattoni Sergio , Stefanazzi Alberto
Published: June 2022

Although closely related with the building structure and required to possess adequate resistance to the acting loads too, the new cladding systems have shown not infrequently inconsistencies or mechanical deficiencies, such as to compromise their safety. The paper shows the necessity of studying and solving the structural aspects of façade claddings through proper numerical modelling and laboratory test, defining a systematic methodology for the evaluation of the structural aspects of the façade cladding that can be used both in case of new construction and building refurbishment.
