FULL PAPER: Earth for social housing in Palestine: an alternative for a sustainable refurbishment of building’s envelopes

2016

The suitable climates in the cities of Jericho and Gaza boosted the emergence of new attempts to revive earthen architecture on organizational and individual levels. These attempts produced a number of earthen buildings in the last few years following the crucial need to find alternative low cost material instead of natural stone, which is used in a large scale in Palestine. Similar attempts had a certain response to the social needs and economic situation there. This paper focuses on the possibility of using earth as an alternative material to refurbish the envelopes of existing housing units including two categories; firstly, refurbishing envelopes of housing units those were partially de…

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…

THE PERFORATED BUILDING’S ENVELOPE: GUIDING THE EARLY DESIGN PHASES

In passato gli involucri edilizi perforati sono stati talvolta ricondotti ad alcuni elementi architettonici tradizionali (come, ad esempio, la ‘Mashrabiyya’), in cui gli elementi forati acquisiscono quasi significati archetipici, nell’assumere ruoli tecnologici e ambientali che rispecchiano i valori della comunità, le condizioni socio-economiche e le esigenze ambientali degli occupanti. Oggi, invece, l’involucro edilizio perforato costituisce una tendenza architettonica che ha iniziato a manifestarsi a livello globale all’inizio del nuovo millennio, alla quale ha contribuito l’emergere della tecnologia digitale con i suoi effetti sull’innovazione di tecniche, materiali, realizzazioni, prest…

Local test of random labelling for functional marked point processes

2022

We introduce the local t-weighted marked nth-order inhomogeneous K-function, in a Functional Marked Point Processes framework. We employ the proposed summary statistics to run a local test of random labelling, useful to identify points, and consequently regions, where this assumption does not hold, i.e. the functional marks are spatially dependent.

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…

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
