Abstract
Day lighting is one of the important qualitative factors in housing, which is also effective on health and well-being of occupants. Extensive glass surfaces and Transparency in building facades provides good daylight quantity for interior spaces. However, this lighting system is not appropriate for climates faced with higher sunlight radiation (Such as hot-humid areas), due to overheating and disturbing the thermal comfort. There are efficient day lighting strategies in the traditional Iranian architecture as one of the valuable remaining heritages of Human experiences, which are useful for contemporary architecture. This article intends to investigate daylight quality in the houses of Bushehr from Qajar period by modeling and simulating in daylight calculation software (Dialux) and identify day lighting strategies utilized in these houses. As Bushehr city is located in the hot-humid region of Iran, is faced with high sunlight radiation, making balance between receiving light and heat gain through windows needs careful attention. The houses of Qajar period in Bushehr are evolved samples of traditional architecture in the city and Rashidy house (built in 1893) is one of them which its form and details can reveal many lessons on coping with climate by merely using renewable energies.

Abstract
Various methods have been employed in vernacular architecture, to achieve energy efficiency in different regions worldwide, especially in facade designs. In Iran, most vernacular buildings are still in use without major modifications and renovations, even in harsh climatic conditions. This study uses mathematical analysis to conduct a quantitative approach toward principles used in the façade design of Bushehr's vernacular architecture. The research critically examined the physical characteristics of eight residential buildings, which were selected as case studies. These parameters included window-to-wall ratios, the surface area for each facade, and the size of different openings concerning height and weight. These physical characteristics of the selected houses were systematically extracted for both the interior and exterior facades, delineating eighteen criteria. The statistical analyses were done using IBM SPSS Statistics version 16.0. The results revealed fourteen linear models—six models related to the exterior facades, five models concerned with interior facades, and three models about the opening. Although the linear models are specific to the vernacular architecture of Bushehr, the research method and approach outlined in this study have the potential to contribute to a framework that can be used by other researchers to uncover underlying principles in vernacular facades elsewhere around the world.
