Benefits of a translucent building envelope made of DSC-integrated glass blocks
2015
The aim of this paper is to analyse the benefits deriving from the replacement of the glazed façades of an office building located in Palermo (Sicily) with a new translucent BIPV envelope made of multifunctional glass block panels integrated with Dye-sensitized Solar Cells (DSCs). The analysed 11-storey building is cladded by a curtain wall determining high management costs, especially during summer, in order to maintain indoor comfort. After the design of the building envelope and of the components for the connection of the glass block panels with existing load bearing structure, the energy performance of the building, before and after the replacement of its envelope, were analysed with th…
Controlling Thermal Flows through Natural Materials in Building Construction Sector
2019
Nowadays, the attention about the building sustainability is increasingly emerging, because of the major responsibility of the building field on the environmental degradation: both in terms of energy consumption from non-renewable sources and the raw materials impoverishment. In addition, the level of comfort required by users is growing and the thermal insulation of buildings becomes the key element for the reduction of energy consumption and CO2 emissions, both in the case of new construction and of the existing ones. The heat load of a building depends on the presence of insulating material which defines the performance of the building envelope. The main purpose of this work is both to i…
DSSC-integrated Glassblocks for the construction of Sustainable Building Envelopes
2014
The paper shows the first results of the optical performance analysis carried out on the DSSC integrated glassblock, an innovative building product developed at the Department of Architecture of the University of Palermo. In the field of a research that is being conducted in order to define innovative solutions for the construction of photovoltaic and energy efficient translucent building envelopes, different hypotheses of integration of DSSC into the glassblock have been foreseen. The integration of glassblock with third generation PV systems allows to define a novel building-PV product that meets the current requirements of the BIPV (Building Integrated Photovoltaics) market. By means of …
Integrazione di celle solari di terza generazione nel vetromattone per la realizzazione di pannelli traslucidi fotovoltaici. Analisi prestazione e st…
2013
L’articolo illustra i primi risultati ottenuti nell’ambito dell’analisi prestazionale del vetromattone fotovoltaico, un prodotto edilizio innovativo derivato dall’integrazione di celle fotovoltaiche di terza generazione (DSSC) nel vetromattone, ideato per la realizzazione di involucri traslucidi energeticamente effi cienti ed “attivi”, in grado di ridurre i consumi energetici degli edifi ci e di produrre, al contempo, energia verde. 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…
Façade Solar Control and Shading Strategies for Buildings in the Mediterranean Region
2020
With the pressing need for holistic solutions that can help in overcoming the imminent environmental and resources crises, a call for the conservation of natural resources and sustainable strategies is needed. Sustainable strategies allow for the mitigation against the impact of climate change on the environment while, simultaneously, seeking the health and comfort of users. Another environmental issue that is worthy of the attention of the scientific research community is the reduction of resources consumption, through the implementation of sustainable development concepts and the use of renewable sources of energy generation. These two aforementioned paradigms are both intrinsic in nature…
Design and performance of sustainable and translucent building envelopes made of ETFE cushions
2009
The paper reports the first results of a research carried out at the Department of Design and Building Construction of the University of Palermo aimed to investigate the problems related to the performance improvement of the building envelope components able to gain the sunlight. In particular we have investigated the development of sustainable building envelopes made of ETFE (Ethylene TetraFluoroEthylene) cushions. The paper shows the problems related to physics, techniques and construction derived from the use of ETFE by analysing the first use of this innovative material for the construction of more recent sustainable building envelopes all over the world. Because of the few studies avai…
Transparent and sustainable materials
2013
The search for greater transparency in buildings characterizes the current architectural scenario: the use of glass is more and more common in both the design of new buildings and for renovation. However, the design of the transparent part of the building envelope is critical to the achievement of efficiency and sustainability. There are several research companies that aim to improve the energy performance especially of the glass. Today there is a wide range of products capable of providing different solutions, depending on the aesthetic and technical requirements of the structure in question. The aim of this article is to provide a clear overview of the possibilities of the transparent mat…
Integrazione di celle solari di terza generazione nel vetromattone per la realizzazione di involucri edilizi traslucidi fotovoltaici
2013
L’integrazione di celle solari di terza generazione - Dye-sensitised Solar Cells (DSSC) - nel vetromattone consente di ottenere un prodotto edilizio in grado di generare energia pulita, personalizzabile in termini di colore, livelli di trasparenza e fi niture, adatto alla realizzazione di componenti edilizi fotovoltaici, traslucidi e multifunzionali, facilmente integrabili nelle chiusure degli edifi ci per la costruzione di involucri edilizi energeticamente effi cienti ed attivi anche in contesti climatici avversi, quali possono essere quelli del Mediterraneo e delle aree subtropicali. L’articolo illustra 4 differenti ipotesi di integrazione delle DSSC nel vetromattone fornendo, per ciascun…
