Materiali cementizi fotocatalitici per il rivestimento superficiale di edifici
2009
Innovative cement-based pre-mix products developing photocatalytic activity for surface coating of buildings is a particularly interesting way to improve environmental conditions in urban centres. These products are particularly suited to be used in the historical centres of cities, where, by necessity tied to the movement of people and goods, it is not possible to close the streets to vehicular traffic, so determining a substantially condition of air pollution. The study describes some pre-mix products, containing mineral pigments, the assessment of their photocatalytic activity, using a well-established testing method and shows how the results are influenced by different aging conditions …
Un regolamento edilizio per la gestione sostenibile della città
2014
Nel nostro Paese, in particolare in Sicilia siamo indietro rispetto ad altre realtà europee nella capacità di gestire l’ambiente in modo sicuro, sano e rinnovabile. Gli edifici hanno un impatto sull'ambiente di diversa natura: occupano suolo, eliminano vegetazione e ostacolano il deflusso delle acque, consumano risorse, materiali ed energia per la loro realizzazione e durante tutta la loro esistenza. Il concetto di qualità energetica ed ambientale degli edifici, richiede di essere tradotto in pratica mediante strumenti concreti. Nel contesto italiano, quello più efficace è sicuramente il Regolamento Edilizio Comunale, che contribuirà a disegnare la Palermo del futuro, più vivibile e sosteni…
L’APPROCCIO TECNOLOGICO PER L’EFFICIENZA ENERGETICA E LA SOSTENIBILITÀ DEL PROGETTO
2012
Il progetto sostenibile dell’edificio, per la complessità tecnologica delle esigenze da soddisfare, l’ingente impiego di energia e il conseguente impatto sull’ambiente, impone una strategia progettuale integrata tra le diverse discipline e aspetti coinvolti (architettonico, tecnologico, impiantistico, ambientale, etc.). I caratteri morfologici e tecnologici del progetto e la natura dei materiali influiscono fortemente sull’efficienza energetica, il comfort interno e l’impatto ambientale durante il ciclo di vita, aspetti tra loro fortemente interdipendenti, su cui ormai da tempo è rivolta l’attenzione della comunità scientifica e degli enti normatori nazionali ed internazionali. L’articolo p…
La conoscenza e la manutenzione degli edifici scolastici. Le scuole a Palermo dal secondo dopoguerra
2013
Il testo affronta lo studio degli edifici scolastici destinati a scuole elementari, costruiti a Palermo dal secondo dopoguerra. Sono descritte le tipologie costruttive sulla base di documenti di archivioe con riferimenti alla coeva produzione nazionale.Infine si tratta il tema della manutenzione degli edifici scolastici.
New digital instruments for the community building in housing cooperatives
2019
The research starts from a study carried out for Confcooperative Habitat, which focused on the systematic analysis of the materials produced for the launch of a new season of the cooperative movement. The goal is to improve the active action on communities for a tangible social impact able to propose a model that knows how to enhance the common urban spaces within the interventions. Finding the new needs and the new processes that characterize living, outlined also in their condominium and urban dimension of ‘common good’, therefore of ‘common housing’. The procedural model proposed and modulated in an evolved platform, seeks to multiply the common practices of living in the city and live i…
The Italian Prisons: An Emblematic Case of Chance of Improvement of a Public Service
2015
The history of prisons is full of pains and contradictions in every historic period. Detention should be seen as a moment of transformation of an offender in a rehabilitated subject. To do this, we need adequate structures, which are able to support individuals by offering them the opportunity, "which in civil life did not have or have not been able to exploit", therefore, prisons where the prisoners do not spend their time lounging due to the absence of any activity, not a structure without services such as the library, recreation centre, etc. as well as not a dilapidated structure and hygienically deficient. A reintegration process has to take into account the place of the reintegration. …
The economic and environmental sustainability in the choice of materials to improve the performances of existing buildings
2015
The concept of sustainability in the construction industry cannot, above all in this historical moment, include in its parameters considerations about economic, social and environmental factors. All this factors are deeply connected with the context, both for climatic reasons and for economic and social reasons. Technical valuations about the choice and use of materials must be motivated by reality in which we work, in the perspective of quality of process as satisfaction of the users but also, in this case, of the producers. The aim of the proposed study is the valutation and individuation of suitable materials for the improvement of the energetic performances of existing buildings which w…
The assessment over time of the performance of jute-basalt hybrid composites for cladding panels
2017
The technology of dry assembly to produce multi-layer panels is an efficient alternative to traditional systems. Eco-sustainable systems are increasingly studied, particularly fiber reinforced composites for external cladding, based on natural fibers. Nevertheless, durability data on these composites are still lacking, being this is a really actual theme, especially for their potential use in outdoor applications. In this way, hybridization of natural fibers with mineral fibers as basalt ones appears promising. In the present paper, the performance of jute-reinforced laminate was compared with those of two jute/basalt reinforced hybrid laminates. The laminates were manufactured by means of …
The durability of basalt fibres reinforced polymer (BFRP)
2014
The technology of dry assembly for the production of multi-layer panels has evolved over the past 30 years, becoming an efficient alternative to traditional systems. The direction taken by the market has been increasingly drawn to eco-sustainable systems and in this way, the interest in the use of laminated composite panels for cladding, basalt fibres based. Basalt is a natural rock, silica based, which is produced through a variety of industrial processes into filaments, wool, chopped strands and fabrics. It is characterized by high resistance in chemically aggressive environments, high fire resistance, high mechanical resistance to compression and bending. The study focuses on two types o…
Calcestruzzo autocompattante siciliano: un'esperienza con il filler vulcanico dell'Etna
2009
Self compacting concrete is one of the last developments in the technology of concrete, being studied and improved from the first '70es. Its production is connected with the use of fillers, most of which coming from iron metallurgy, scarsely present on Sicilian territory. So, the aim of the risearch was to realize self compacting concrete using exclusively local filler, particularly the Etna ashes with a strong pozzolanic connotation, pointing out the use of useless at the moment natural resource. The study relates to the verification of the more appropriate mix-designs and the tests on compressive strength of specimens to early curing and after 28 days. Different characterization tests wer…
