The contribution of natural light and visibility in the optimization of visual comfort

Case of traditional habitat in Arris dechra

Abstract

Understading vernacular humain settlements remains arduous and very complicated. This issue leads to an eronous perception and a bad division of spatial systems. The present work aims to know and understand the source of natural light in traditional habitats presenting practically only blind facades, this poses a problem concerning the way in which we seem to get a sufficient natural lighiting for a visible and confortable habitat while respecting identity of the locality. Through the present research based on observation in-situ, the questionnaire survey and the syntactic study of these traditional dwellings in Arris, we concluded that the courtyard is the source of natural light in these habitats.
