Résumé: ABSTRACT This study aims to evaluate the 50 duplex dwellings of the El Miniawy brothers in M'Sila, usingmethods of analysis of environmental strategies in order to verify their application by thearchitects in the construction of these dwellings. A duplex dwelling was selected to undertakean analysis using a mixed methodological approach, combining a qualitative and quantitativemethod, some of whose strategies were evaluated using the EnergyPlus software and validatedby in situ measurements. The results showed that duplex housing has been subject to theapplication of the strategies in question. We therefore deduce that the construction is efficientand that it ensures the comfort of the user and reduces the negative environmental impact.This study could constitute an alternative for architects, building designers, planners anddecision-makers in order to encourage them to adopt these neo-vernacular environmentalstrategies of El Miniawy in the development of similar projects in M'sila, and to launch otherprojects with a contemporary vernacular character.

Résumé: After having its own independence, Algeria has oriented its development towards industrialization, in which the effects were so destructing for the built environment. As result, we notice that the same architectural style was diffused everywhere of the country. That has created a contradiction with the ancestral traditions, this way of construction has intensified the phenomenon of rupture between man and his local environment. André Ravéreau and Fernand Pouillon, two modern designers who worked in Algeria, have innovated in their visions, by privileging the return to local sources as well as traditional architecture, but different from their peers, stemming from the modern movement that favorite concrete. Nowadays, although they introduced new techniques of construction but they made traditional aspects as reference; the contemporary architecture can-not be possible and achievable only through a reinterpretation of modern designer’s master works in Algeria. This work was fed by exits on ground, grip of photos, interviews with the persons in charge and the owners.

Résumé: Nowadays, architectural creation is in a state of degradation. In fact forms and architectural styles show a lack of environmental aspiration. The studies in this area have revealed that the problem is directly related to the lack of coordination between architecture and the environment.
