Abstract

Masonry units are considered to be traditional and environmental materials used in constructing valuable buildings in historic and Heritage sites all over the world. And they are well known for either construction or claddings up-till now. But they sound for various problems while using them in traditional ways as; the massive weight, the limitations of constructing large spans, the low durability while absorbing water or facing more stresses. Moreover, they are costly while maintaining them.Nowadays the call for sustainable development forced technology to convert the massive material to a smart one which could deal in the site with efficiency as economically or environmentally as called eco- efficient aspects. So the liability issue is that; there is no researches (especially in Egypt in the field of the conservation of the heritage buildings) refer to the usage of the smart masonry in the heritage buildings or the advantages that could be gained by that usage.The research aim to get important role of smart technology to search for the aspects of efficiency that could be presented in the global era to get solutions to revive the usage of masonry units in the heritage buildings in new integrated constructions or in the additions of the heritage buildings themselves, all within the scope of the sustainable development.There are two hypotheses in the paper as follows; the first considering that the global technology afforded the construction process by smart materials and systems that can represent many kinds of efficiency suiting the sustainable development.The second hypothesis: is that the smart masonry have great efficiency while using them in the rehabilitation projects of the heritage site.The methodology used in this paper to fulfill the hypothesis and reach the main aims is a deductive method begins with a theory(Displaying the new technical masonry and their advantages as means of reaching eco efficiency), and developing hypotheses from that theory(by Assessing the validity of the hypothesis concerning the needed efficiencies of the used construction in the heritage sites, by means of questionnaire directed to the persons concerned the heritage sites development), and then collecting and analyzing data to test those hypotheses(by measuring the efficiency of using the new technical masonry in the additions of the constructions in the heritage buildings, by means of questionnaire directed to the persons concerned the heritage sites developmentcivil engineers and industrialists).
