Attention to daylighting methods in traditional houses is one of the prominent features of the rich vernacular architecture of Iran. Therefore, recognizing the experiences of the predecessors about the transparent surfaces of the indigenous houses of Tabriz city which is located in the cold-dry climate of Iran and updating the previous strategies can improve the quality of daylight in contemporary buildings.
This paper examines physical elements of the open and closed spaces in the traditional houses of Tabriz and their role in increasing the quality of daylighting and sunlight hours in the interior spaces, analyzes the logical relationship between the components of transparent surfaces and the closed spaces associated with them.
The purpose of this study is to recognize quality and sunlight hours of traditional houses of Tabriz and to provide suggestions and design patterns for closed spaces in this city buildings and cold-dry climate buildings in Iran. The research method is based on data collection, field studies and the use of daylight analysis software to check the illuminance of the spaces, sunlight hours and shading in the yard throughout the year. Standards related to daylight quality and statistical methods were used to analyze the obtained information. The results indicate the existence of a logical relationship between some elements of window and room in the closed spaces related to windows that provide adequate daylight, which is presented as proposed design patterns
