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…
Energy retrofit actions on Italian historical buildings: energy efficiency and feasibility. A review study.
2016
Today in EU, the growth in global primary energy consumption is decreasing. In 2014, Italy contributed with a global reduction of 17.1%, thanks to the application of EU measures on different areas. However, there is still much work to be done in order to make sustainable societies and territories, especially in buildings sector that has the greatest potentiality of energy saving. In particular, in the framework of Conservation, Restoration, Refurbishment, and Retrofit actions, the debate is still open, because many aspects must be considered and solved yet. In this paper, the state of the art of the Italian residential building heritage has been reviewed, applicable energy retrofit issues a…
Space syntax analysis applied to urban street lighting: Relations between spatial properties and lighting levels
2019
According to the international technical standards, higher lighting levels (luminance and illuminance levels) are expected in trafficked and central roads (where restrictive minimum lighting requirements are necessary) and lower lighting levels are expected in peripheral and less trafficked roads. Starting from this assumption, in this paper, the authors analyse the correlations between spatial properties (expressed by spatial indicators, for example, the integration index and the choice index) and lighting levels (expressed by lighting parameters, for example luminance and illuminance) upon roads of an urban context. The analysis has been applied to the case study of the medium sized town …
Reviving earthen architecture in Palestine: The added significances of the building sustainability and an opportunity for the future
2016
Several attempts have emerged recently in Palestine aiming to find an economical-environmental alternative building material beside the widely-used natural stone as a main building material, due to some factors related to the cost and the negative effects of stone mining areas on the local environment. Similar attempts had a certain response to the peculiar social needs and economic situation there. The efforts led to revive earthen architecture on organizational and individual levels, producing a certain number of earthen buildings in the last few years. In order to evaluate the appropriateness of earth as an alternative raw material in Palestine, the paper outlines the general advantages …
EARTH FOR SOCIAL HOUSING IN PALESTINE: AN ALTERNATIVE FOR A SUSTAINABLE REFURBISHMENT OF BUILDINGS’ ENVELOPES
2015
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.

Interventi migliorativi in acciaio a tutela delle opere di interesse storico-monumentale dal rischio sismico
2007
The research concerns the analysis of structural behaviour of some historic-monumental buildings in which steel structures are used for the seismic protection. A dynamic model has been made to individuate the macro-element with an high seismic risk, that is, for church studied, the drum-dome system. Then a scaled model has been tested to determinate the evolution of the lesions, the retrofitting works, that are constituted by steel frames, bare or braced, inserted inside door/window holes of the drum-dome system, and the variation structural ductility. An elastic linear analysis, with a FEM software, has been developed for other type of buildings, in which the vertical structures are made w…
Progetto di Strutture in acciaio per le nuove costruzioni e per gli interventi di consolidamento. IV Edizione
2005
The book is a state of the art summary of recent development in the behavior, analysis and design of steel and composite structures. The book provides advanced students, researchers al professionals in civil and structural engineering with the basic principles upon which the modern codes are based. In the first part, the materials, the actions and the sectional behavior are analyzed on the base of the limit state theory. Then the connections (bolted and welded)and the stability effects are examined. In this way is possible speak about seismic performance, retrofitting an refurbishment of existing buildings, referring to the italian rules, to the european codes EC3, EC4 and to the AISC rules.
