Manifattura Tabacchi
2015
La Manifattura Tabacchi di Palermo trovò la sua sede verso la fine dell''800 negli edifici che avevano ospitato il Lazzaretto della città, sulla via Simone Gulì, tra gli attuali Cantieri Navali ed il Cimitero degli Inglesi, sulla costa che nei secoli ha subito sostanziali modifiche. Ciò che rimane del corpo ad emiciclo ed il quadrangolare con cortile interno risalgono al 1833, quando furono costruiti per ingrandire il Lazzaretto, su progetto dell'arch. Niccolò Puglia. A questi edifici, in occasione del cambio di destinazione d'uso da lazzaretto a Manifattura Tabacchi, ne furono accostati altri nel 1885, per ospitare le macchine necessarie alla fabbricazione di sigari e sigarette. L'edificio…
Artificial Neural Networks to assess energy and environmental performance of buildings: An Italian case study
2019
Abstract Approximately 40% of the European energy consumption and a large proportion of environmental impacts are related to the building sector. However, the selection of adequate and correct designs can provide considerable energy savings and reduce environmental impacts. To achieve this objective, a simultaneous energy and environmental assessment of a building's life cycle is necessary. To date, the resolution of this complex problem is entrusted to numerous software and calculation algorithms that are often complex to use. They involve long diagnosis phases and are characterised by the lack of a common language. Despite the efforts by the scientific community in the building sector, th…

Recent Development on Self-Cleaning Cementitious Coatings
2013
The recent improvements in nano-technologies applied to building coatings are reported, starting from the historical origins of the research on photocatalysis. The description of the main air pollutants and the chemical mechanism of photocatalysis introduce to self-cleaning surfaces and the super-hydrophilic and hydrophobic attitude. Self-cleaning cementitious surfaces, due to nano-structured photocatalysts, mainly titanium dioxide, show environmental benefit in reduction of air pollutants and many experimental evidences are reported together with several applications on building construction. International standards and main spectroscopic techniques aim to evaluate the benefit in terms of …
Photocatalytic properties of cement-based plasters and paints, containing mineral pigments
2010
Innovative cement-based pre-mix products, for surface coating of buildings, possessing photocatalytic activity, arouse great interest due to achievable results in terms of reduction of the air pollution and in the maintenance of aesthetics.The photoactivity is induced by the presence of a photocatalyst, titanium dioxide, which can accelerate the oxidation processes of air pollutants, particularly nitrogen oxides (NOx) and volatile organic compounds (VOCs), mainly produced by incomplete combustion of fuel and present in urban environment through the exhaust gases of motor vehicles. The surfaces which are coated with these products acquire a self-cleaning characteristic (maintenance of origin…
The durability of basalt fibres reinforced polymer (BFRP) panels for cladding
2015
The study focuses on two basalt composite laminate panels for cladding, produced by means of vacuum bagging technique. In particular, unidirectional and random basalt fabrics, with different areal weights, using epoxy resin as matrix, were used. According to the ISO 15686 methodology for the evaluation of durability, samples were subjected to cycles of artificial aging in climatic chamber and outdoor exposure, carrying out mechanical (i.e. quasi-static and dynamic) and calorimetric tests. The results show the effectiveness over time of produced basalt composite laminates and the initial increase of the mechanical performances after the first steps of accelerated aging.
Smart city and public lighting
2015
The smart city is increasingly becoming a concept of reference for what concerns the planning and the spatial development of cities. The concept of smart city cannot be easily standardized. It is based on a multi-service and multi-sectorial planning regarding various urban functions (energy, mobility, waste, etc.) and places them under a common denominator: the use of advanced technologies for minimizing resources consumption and simultaneously increase the quality of life of the citizens. This paper aims to give an overview on the concept of smart city and outline what, at present, are the main intervention areas considered at European level. Then the paper focuses on the public lighting t…
The effects of a saline environment on the durability of commercial photocatalytic paints
2016
The use of photocatalytic products for surface coating of buildings ensures the reduction of certain air pollutants and greater duration of color over time, due to the reduced attitude of air particulate to adhere to the treated surfaces. The world market is producing a wide range of coatings, transparent and opaque, high initial performance, but there is a lack of data on their durability. The knowledge of performance over time of these new products is at the basis of the Regulation (EU) no. 305/2011, which repealed Council Directive 89/106/EEC and introduced the seventh requirement regarding the sustainability and particularly durability of construction works. This study focuses on the as…
