Abstract
Bandar-Lengeh is located in a region with a hot and humid climate in the south of Iran. As a result, given its harsh weather conditions, several elements and spaces have been devised to create a special kind of sustainable architecture, a Baber-Room. Since there is no evidence of any scientific study regarding Baber-Rooms or their analysis, this research has been conducted in two parts, structural and functional, to better understand them as a stable structure. To examine these, an area of Bandar-Lengeh was chosen (36 houses aged 70 or above) for a qualitative (introducing the Baber-Room, its components, materials, and construction process, the occupied areas, orientation, and positioning) and a quantitative study (light-measurement using Ecotect analysis software and temperature measurements with a “Fluke T3000fc” device). This was done at a time when mechanical air-conditioners were not standard, to see whether these rooms could meet the needs of inhabitants as natural air-conditioners.
