Glassblock and Architecture. Evoluzione del Vetromattone e Recenti Applicazioni

2010

Il vetromattone è stato impiegato, sin dalle origini, per la risoluzione di problemi connessi alla necessità di aumentare l'apporto di luce naturale all'interno di ambienti confinati contribuendo, in tal modo, anche alla riduzione dei consumi energetici (elettrici, in particolare). La sua applicazione assolveva già in nuce, quindi, ad alcuni dei principi derivati dal più moderno concetto di “sostenibilità” applicato al settore edilizio, anche se solo oggi le ricerche condotte in ambito scientifico e produttivo mirano a tener conto sensibilmente delle problematiche ad esso connesse, soprattutto in rapporto alla produzione e messa in opera del vetromattone. Il libro trae spunto dal convegno i…

L’analisi è stata condotta su quattro differenti ipotesi di integrazione. Attraverso simulazioni numeriche si è effettuata una valutazione dell’energia assorbita dagli strati attivi oltre che delle prestazioni ottiche complessive del dispositivo. Lo studio anali…

In this article the fi rst results of the performance analysis of the photovoltaic glassblock are given. The photovoltaic glassblock is an innovative product which integrates third generation solar cells (DSSC) invented for the construction of translucent building envelopes energetically effi cient and “active” able to reduce the energy consumption in buildings and to produce at the same time green energy. The analysis was conducted on four different hypotheses of integration through numerical simulations in order to evaluate the energy absorption and the optical performance of the device. The software simulations represent a fi rst step for the understanding of the performance of the element and prelude to an experimental analysis session. The results of a research conducted about national and international patents publications on the DSSC technology and its applications will be illustrated too. The data collected during this research had been organized in a digital database.Settore ICAR/10 - Architettura Tecnica

“Hypotheses of Integration of DSC into the Glassblock for teh Construction of Translucent Building Envelope”

2012

New configurations of the glassblock have been designed at the Department of Architecture of the University of Palermo in order to reduce its U value responding to the latest national and international regulation limits for the thermal insulation of the buildings with glass façades. One of these new configurations consists in the insertion of a special plastic "belt" between the two glass shells composing the glassblock, which have to be glued to it (cold assembly); the plastic belt effectively interrupts the thermal bridge between the two glass shells. Thanks to the particular design of its shape, the "thermal belt" can be also used for the insertion of one or more additional sheets of dif…

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
