This paper aims to study the impact of sunlight and daylight on the dwelling's design in Algeria. The approach used for this purpose is the theory of structuration. In this work, the home is considered as the behavioural setting and five case studies are investigated from the coastal area of Algeria to its Sahara desert: traditional houses of Algiers, Kabylie, Constantine, Aures and Ghardaia. The preliminary outcomes presented in this paper are part of a broader research including people's reactions and attitudes, of an Islamic culture, towards various daylighting and sunlighting strategies in different working and living spaces
