Plaster ventilated façade system for renovating modern and ancient buildings. A CFD analysis
In the past decades several researches have been related to energy saving and emissions reduction. The technologies that exploit passive natural ventilation, like ventilated roofs and fa ades, have been recognized as the effective methods to provide energy saving and comfort. Ventilated fa ades represent dry assembled coating systems for buildings, traditionally made of panels in different materials. Very few ventilated fa ade systems with plaster finishes are already present on the building market. The potentiality of their design solution can be considered, e.g., when an historic building has to be recovered, since they can enhance the energy efficiency of building without changing its ap…
Analysis of Renovation Works in Cappuccinelli Social Housing District in Trapani
The refurbishment of public residential districts represents a current and complex problem. The Cappuccinelli Social Housing (SH) district in Trapani, designed in the late 1950s by Michele Valori and built during the 1960s, is emblematic of the architectural quality and technological innovation of the time it was designed, but at the same time represents the physical and social decay that occurred just after its construction. The neighborhood was examined through a combination of inspections and documentary research. The inspections were conducted for the entire district in order to identify the recurrent external degradation of building components and the related causes, both physical and …
Approccio integrato per la caratterizzazione delle murature storiche siciliane. Il caso di Gangi
This study is part of a research aimed at developing a database of mechanical and hygrothermal information for Sicilian historic walls. This database is intended to support the analysis of the envelope performances of the historic building and to integrate data collected through in-situ measurements. The method is based on the analysis of local contexts: stone walls are divided in typologies according to the detailed non-destructive examination of the historic building stock, and laboratory and in-situ tests are carried out to characterize the mechanical and thermophysical properties of walls and masonry materials. This study focuses on the local context of Gangi, where a large amount of hi…
Integrating thermal and mechanical characteristics of historic masonry categories: Development of a Sicilian database
Detailed construction analysis is essential to the compatible energy improvement of historic buildings. In-situ measurements are crucial for energy diagnosis but their use is limited, especially in vernacular architecture. This paper exposes the development of a hygrothermal and mechanical database for Sicilian historic walls. The proposed method, applied to eleven historic centres, is based on the investigation of those masonry construction features, which recur in local contexts. Preliminary results concern the case study of Petralia Sottana, where a first set of laboratory measurements of stone compressive strength and thermal conductivity was conducted, together with in-situ tests of ma…
