Using a systematic sampling method housing units were survey

Using a systematic sampling method, 120 (20%) housing units were surveyed from a total of 600 units in Oniru estate. Only 100 (83%) copies of the questionnaire were retrieved from the respondents and used for analysis. The data were analyzed by use of descriptive statistics and the Pearson Chi-square test in determining the significance of identified physical characteristics on residential satisfaction (with probability level p<0.05).

Conclusions
Introduction Considering the increasing number of new demands due to the principle of “sustainable“ development based on a search for a more careful contextuality and on a attempt of conciliation of cultural ideas with the potentiality of technological change, the brand new architectonic cultural path is moving through a process of critical and current re-interpretation of the traditional building materials and systems. The characteristics of traditional materials, such as natural stone, enhanced by technological innovations, are often capable of providing excellent performance (Lombardo, 2005). From the environmental point of view we can say that natural stone has several features that give it vorapaxar a sustainable behavior (Lombardo, 2004). It, produced naturally, is able to accomplish, on its own and consistently in long periods of time, diverse tasks (aesthetic characteristics, environmental value, building reliability, static security, endurance, protection from atmospheric agents, thermal and acoustic protection, fire resistance, etc.) so it represents an alternative to new modern architectural materials which have, on the contrary, often shown an early decadence. From the standpoint of processing, the stone in the various phases, produces waste that can be used as inert or to make filling, fills detected and also worked quarries (DLgs 152/2006) (Cicero and Lombardo, 2011). The manufacturing process requires only electricity consumption to power the machinery for the stone working, unlike other building materials such as brick and concrete, where the cooking in fueled ovens could produce polluting emissions in the air (Hammond and Jones, 2011). For instance, natural stone is currently having a moment or “Renaissance” in which it is being used in new shapes and expressions. Also related to its structural vocation by many contemporary designers such as Renzo Piano, Michael Hopkins, Kengo Kuma, Peter Rice, etc. Lombardo (2005). Within this problematic, at the department of architecture of University of Catania, research has been started with the objective to study a new constructive procedure of reinforced masonry, using natural resistant elements made of blocks of lava of natural stone (Etna basalt), in order to create new architecture stone with organic forms, more free in the space than in the past (Lombardo, 2004). From a technological point of view, research has defined the load-bearing masonry constructive procedure in all its parts. It is of an integral type with modular components, consisting of blocks of basalt with square parallelepiped geometry and mortar, inside of which it is possible to insert steel bars according to the structural requirements (Lombardo, 2004). The analysis of the structural behavior allowed us to establish the related values of the characteristic defining the deformation and the mechanical resistance of the model taken into account for the defining of the calculus parameters. The experiments were performed at the Laboratorio Ufficiale Prove Materiali of University of Catania. In accordance with the data reported in Table 1, deriving from the compression tests it appears that the values of the characteristic resistance are greater than the values (in accordance with the law) allowed by the permitted standard (Lombardo, 2007). The seismic tests showed how it is possible to build a spiral with a sloped, prestressed wall, with a thickness of 20cm, highlighting the considerable increase in resistance of the panel, compared to one that is only reinforced to resist against out plain actions (Lombardo, 2010).
