“…Furthermore, if the ventilated façade is realized with plaster finishing (Figure 9), heat flow can be reduced up to about 70% due to the effects of the ventilation [21]. Compared to modular panels, an outer layer made of plaster minimizes the visual impact of the renovation and preserves the urban and architectural features of the buildings.…”

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 anthropogenic. This paper investigates the physical–mechanical degradation and problems connected to previous renovation work in this district. Furthermore, technological design solutions are discussed for deep renovation and energy efficiency improvement of one of the terraced buildings of the Cappuccinelli SH district.

“…Considering the wide-range of BIPV technologies, their tailored implementation has the potential to improve the quality of human life under multiple prospects [6,7]. A particularly interesting BIPV application is the implementation of PV technologies in Double Skin Façades (DSFs) [11,12] or Ventilated Façades (VFs) [13], since, as identified by De Boeck et al [14], an improvement in the insulation efficiency of the building envelope is a key parameter to increasing its energy performance. In this regard, DSFs and VFs have been identified as one of the best options to reduce building energy loads [15], as their architectural flexibility allows the interaction between outdoor and indoor spaces to be modified according to the building needs [16].…”

Design of a Ventilated Façade Integrating a Luminescent Solar Concentrator Photovoltaic Panel

The increasing trend towards decarbonization requires the reduction of the environmental impact of the building sector that currently accounts for approximately 40% of the total CO2 emissions of European countries. Even though Luminescent Solar Concentrator (LSC) panels could be a very promising technology to be installed in urban environments, there is still little implementation of LSC panels in building façades. Here, the realization of a Ventilated Façade (VF) integrating an LSC device as an external pane is presented and a preliminary numerical and experimental investigation is used to evaluate the interaction between the different structure components. Thanks to the realization of a dedicated mock-up finite element method, models are calibrated and validated against experimental measurements, showing a good correspondence between simulated and measured data. Moreover, the electrical characterization of the LSC panel confirms that large area devices can be used as an external skin of VF, reporting a photovoltaic efficiency of 0.5%. The system’s thermal and optical properties (estimated thanks to the software COMSOL Multiphysics) encourage the continuation of the research by considering different technologies for the VF internal skin, by scaling up the case study, and by running the simulation of an entire building considering winter and summer energy demands.

“…Considering the increasing demand for space cooling application due to the rise of atmospheric temperature associated with carbon emission and the consequent rise in the sale of air conditioning appliances that has led to serious environmental issues, the adoption of passive cooling techniques plays a vital role (Bhamare, 2019). Among the possible strategies, there are technologies that exploit natural ventilation, both on the roof and on the façade, which are particularly effective in hot climates, like the Mediterranean one, as the ventilated cavity mitigates the effect of solar radiation (Corrao, 2021). The realization of an air layer allows the prevention of the heat transfer through the building envelope consequently avoiding the cooling down of the building form the penetrated heat, which represents a valid strategy not only from the environmental point of view but also from the economic one (Susanti et al 2010).…”

In hot climates, ventilated pitched roofs help dissipating the excess heat, thus reducing the cooling energy demand. The key factor is the so-called Above Sheathing Ventilation (ASV) that depends on the air entering and leaving at the eaves, ridge and the gaps among tiles. A strategy for increasing the ASV is the enhancement of the roof air permeability through the development of new tile shapes, as proposed in the European Life HEROTILE project. The performance of a ventilated pitched roof are experimentally analysed by comparing some covering options: the new tile shape designs against the standard ones, available in the market, and a metal cover. A real scale pitched roof mock-up was built and equipped with a comprehensive monitoring system. The air flow and temperature in the different roof layers, as well as the heat flux passing through the roof and the cooling energy demand, were monitored according to the local weather conditions during the summer season. The analysis showed that the new tile design increases the ASV in comparison with the standard ones, and better thermal performance was achieved by reducing the heat gain due to solar radiation.
