Tectonic Sustainable Building Design for the Development of Renovation Scenarios – Analysis of ten European renovation research projects

2018

The investigation of 10 European building renovation research projects presented in this paper demonstrates that recent research in this field is currently centralized around quantifiable objectives i.e. development of energy efficient renovation scenarios, whereas the more qualitative objectives in renovation projects such as aesthetics, identity and/or social dimensions are rarely addressed. Furthermore, the result of this investigation together with the recent researches about the current practice of building renovation indicates that many of renovated buildings, which now are claimed to be sustainable are not addressing all aspects of a conventional definition of sustainability. Lastly,…

Effect of Cu-Zn coated steel fibers on high temperature resistance of reactive powder concrete

2019

Abstract Even though many studies have reported about the impacts of shape, length and distribution of steel fiber reinforcement on global concrete properties, there is a lack of information about the influence of coating type of steel fibers on high temperature resistance of concrete. This paper describes the effect of Cu-Zn coated steel fibers on selected properties of reactive powder concrete (RPC) after exposure to elevated temperatures. The initial corrosion of zinc in Cu-Zn surface layer is found to be already activated by the alkaline environment of the fresh concrete. The RPC samples reinforced with Cu-Zn coated steel fibers are heated to 600 °C and 1000 °C, and the influence of the…

La stereotomia nella cattedra di Architettura statica di Carlo Giachery

2014

La scuola di architettura di Palermo, sin dalla sua fondazione nel 1779, con la creazione della cattedra di Architettura civile affidata a Giuseppe Venanzio Marvuglia, era divenuta inevitabilmente il luogo di verifica e talvolta di esplorazione dei temi legati alla pratica professionale e, quindi, all’arte del costruire. Giachery, Professore di Architettura statica e civile dal 1837 al 1865, è il primo ad avvertire, da docente, la crisi profonda del sistema didattico della scuola di architettura di Palermo isterilita dalla ricerca di astratte idealità neoclassiche e straniatasi dal processo evolutivo della cultura architettonica europea dopo la morte dei “maestri” Marviglia e Gentile. Secon…

The School of Architecture of Palermo since its founding in 1779 with the creation of the chair of Civil Architecture entrusted to Joseph Venantius Marvuglia has become the place of testing exploration of issues related to professional practice and the art of building. Carlo Giachery Professor of Static and Civil Architecture from 1837 to 1865 is the first to feel the deep crisis of the educational system of the school of architecture of Palermo. For him architecture and applied sciences to architecture found in their stereotomy confirmation of the existence of correspondent relationships in their evolutionary process. The notion of stereotomy taken by Carlo Giachery in teaching reconnects directly to the noble art of coupe des pierres. Taken together the teaching aids used to show a theoretical advance that Giachery inclined in the direction of elasticity of the materials. Noting the outcomes of teaching his students have the clear perception of how the teaching on stereotomy is the compendium of all the French tradition on the subject. With the establishment of the School of Application for Engineers and Architects in 1866 the steretomia seems to gradually lose interest in favor of the prevailing metal construction. All the wisdom of build which for centuries had been linked with art de la coupe des pierres gave way to new construction techniques and new materials.Settore ICAR/14 - Composizione Architettonica E Urbana

La Seconda Vita dell'Ambiente Costruito

2021

Il contributo inquadra i saggi, gli studi, le ricerche e progetti pubblicati sul numero 9 di AGATHÓN su ‘La Seconda Vita dell’Ambiente Costruito’, tema di interesse per il mondo accademico, delle professioni e dell’industria. Cambiamenti climatici, eccessivo consumo di suolo e di risorse non rinnovabili, produzione sempre crescente di rifiuti, emergenza pandemica e crisi socio-economica globale sono entrati di fatto nel nostro quotidiano: seppur drammatiche, per certi versi, tali questioni possono essere colte come un’opportunità per ripensare il modo e il mondo in cui viviamo. In questo contesto di ‘rivoluzione’(Floridi, 2020) e di ‘policrisi’ (Losasso, 2020), e con riferimento specifico a…

The contribution frames the essays studies research and projects published in issue 9 of AGATHÓN on ‘The SecondLife of the Built Environment’ an interesting topic for universities businesses and industry. Climate changes excessive use of soil renewable resources ever-increasing production of waste the current pandemic emergency and the global socio-economic crisis have in fact entered our daily life. Even if these are tragic issues they can be somehow seized as an opportunity to rethink the way we live and our world. In this ‘revolutionary’ (Floridi 2020) and ‘polycrisis’ (Losasso 2020) context specifically referring to the building industry the Academy the Research and Industry worlds are called to give answers – based on sustainability and the principles of the Green Deal but also and mostly of the new Bauhaus – that can encourage reconsiderations and re-orientations of processes and products new projects on places buildings objects and materials able to positively affect the governance of the global change that our planet and humanity need able to give a ‘new life’ to the built and/or transformed environment at any scaleSettore ICAR/12 - Tecnologia Dell'Architettura

La scoperta, sistemazione e conservazione della grande Iscrizione di Gortina, nell'isola di Creta (1884-1921): la protezione delle testimonianze e le…

2013

La scoperta e la conservazione della Grande Iscrizione di Gortina a Creta, da parte degli studiosi italiani, fra la fine del XIX sec. e i primi decenni del XX sec., rappresentò un grande riconoscimento scientifico-culturale per la giovane nazione italiana. Nel passato, l’isola di Creta era stata legata alla Repubblica di Venezia e anche questo rapporto favorì l’invio a Creta del giovane epigrafista F. Halbherr, il quale fra notevoli peripezie rinvenne, assieme all’epigrafista tedesco E. Fabricius, la famosa l’iscrizione nell’antica città di Gortina. L’iscrizione, fra le più antiche e complete finora conosciute in tutta Europa, conteneva le norme sulla famiglia, l’eredità e in generale i dir…

The discovery and preservation of the Great Inscription of Gortyna in Crete by Italian researchers in the late nineteenth century. and the first decades of the twentieth century. was an important cultural and scientific recognition for the young Italian nation. In the past the island of Crete had been tied to the Republic of Venice and this report also favored sending in Crete the young epigraphist F. Halbherr who among considerable vicissitudes came to together to the epigraphist german E. Fabricius the inclusion of the famous ancient city of Gortyna. The inscription among the oldest and most comprehensive so far known throughout Europe the rules contained on the family's legacy in general and the rights and duties of some of the people of the Minoan civilization (480-450 BC). The inscription was carved on blocks organic limestone a restored ancient building which later in Roman times was turned into odeon. The Laws of Gortyn were engraved on the remains of the wall forming the passageway in front of the steps of the odeon. The essay traces the events that led to the discovery and subsequent storage made by Halbherr especially with the help of archaeologist L. Pernier and finally with the help of architect E. Stefani who designed a modern cover on the top of the ambulatory of the segments containing the inscription. This coverage was made to perform during the First World War on the basis of the Italian project from the Greek Government in order to protect the membership from possible war damage but especially from vandalism. The roof brick clay of the Laws of Gortyna still serves its function and ensures the use of the monument bearing witness to the preservation of Italian culture in Greece and more generally in the world. But in Sicily in the remains of the Villa del Casale in Piazza Armerina (Enna) its elegant protection (built in 1957) is representative of a whole period of culture of the Italian restoration is removed and replaced because it has not been able to make a ongoing maintenance is due. A bad example of conservation and management of a UNESCO monument from which arise after the work for the construction of new roofs an equally insulting to the archaeological heritage and scenic Italian and world.Settore ICAR/19 - Restauro

Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica

Pannello precompresso di vetromattoni assemblati a secco per la realizzazione di involucri traslucidi

2012

L’invenzione riguarda la realizzazione di un pannello di vetromattoni montati “a secco” -da impiegare per la realizzazione di involucri edilizi traslucidi anche nel caso di edifici alti- che è in grado di rispondere adeguatamente alle sollecitazioni orizzontali (quali quelle dovute a vento e sisma) grazie all’applicazione della tecnica della precompressione mondirezionale. Per offrire una risposta ai limiti imposti dalla tecnica di assemblaggio tradizionale dei vetromattoni (“ad umido”), l’applicazione della precompressione consente, infatti, di dare ai pannelli preassemblati “a secco” una rigidezza adeguata anche in direzione normale al loro piano di posa, sfruttando le buone caratteristic…

The invention is related to the construction of a glassblock panel “dry assembled” that can be used to build translucent building envelope even in high-rise buildings. This panel is able to contrast the horizontal actions due to wind and earthquake by means of the application of unidirectional pre-stressing technique. To overcame the limits due to the “wet assembly” system traditionally used to assemble the glassblocks the use of prestressing technique allow the panels to have an adequate mechanical resistance against the actions perpendicular to their installation plane. In this configuration the mechanical resistance of the glassblocks is exploited. The unidirectional prestressing (along the prevalent dimension of the panel) is obtained through the grip of the nuts inserted in the steel bars that are housed inside the glassblocks supporting profiles positioned in the vertical cavities between the glassblocks and passing through the horizontal profiles useful to separate glassblock rows from each other. The proper nuts grip opposing to the steel plates positioned at the top and bottom of the panel allow to prestress the panel. The steel plate are positioned on a plastic plate fixed to the lateral faces of the glassblocks by means of resins.Settore ICAR/10 - Architettura Tecnica

Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali

2019

I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…

The projects prepared for "Palermo South-East" are the result of a Graduate Laboratory structured through meetings seminars specialist communications critical exhibitions which - in a shared strategy - saw each student elaborate their work in comparison with others actors of the same Laboratory. The research on "urban projects" was set so that each graduating student was made aware of the projects carried out in the same geographical area by the colleagues who had preceded it so as to be able to operate in continuity and contribute to formulating a unitary reasoning in which each project constituted continuation verification or even variant of the previous ones. These coordinated works have pursued two fundamental objectives: the strengthening of infrastructures and the establishment of specialized public buildings with superior functions aimed at requalifying and regenerating various critical situations with particular attention to the relationship between context and life scenarios. Thus each designer while dealing with a main functional program simultaneously deals with various issues such as the rationalization of the road system the redevelopment of existing buildings the design and refunctionalization of urban services (for example the transformed Central Station in the hotel or the project of a great Mosque)several degree theses have addressed as the main theme or as a question in the background the design of a new bed for the Oreto river and the relative establishment of a park facing it. In this desire to "patch up the wounds" in the different areas of "Palermo South-East" in close relationship with the vicissitudes of the place there is a continuous reference to architectures of all time and some questions involving the functional program are suggested - that identifies the character (or perhaps "type") of what is to be inserted in a given context - and the qualities of living reality as a pivotal material in the design process.Settore ICAR/14 - Composizione Architettonica E Urbana

Building Construction Sets by Tiling Grammar Simplification

2016

This paper poses the problem of fabricating physical construction sets from example geometry: A construction set provides a small number of different types of building blocks from which the example model as well as many similar variants can be reassembled. This process is formalized by tiling grammars. Our core contribution is an approach for simplifying tiling grammars such that we obtain physically manufacturable building blocks of controllable granularity while retaining variability, i.e., the ability to construct many different, related shapes. Simplification is performed by sequences of two types of elementary operations: non-local joint edge collapses in the tile graphs reduce the gra…
