Traditional building technologies have much to teach us about how to design regionally appropriate structures. The Orosi is one of these useful technologies, which has been used for many centuries in order to control the harsh sunlight in Iran. This architectural element was rather important because the intensive solar radiation could easily damage valuable carpets used in most spaces in Persian buildings. The main question of this research was how much could the traditional Orosi windows reduce the harmful spectrums of sunlight? In order to investigate this effect, a combination of field study, laboratory measurements, and case study research method was applied. Nine Persian traditional Orosi windows were chosen as case studies and the windows’ geometric lattice (Gereh–Chini) and glazing color combinations were drawn and plotted. The experiment was carried out for carpeted and non–carpeted spaces. In order to measure the light transmission of the sample tinted glazing from the Orosi windows, a T80+ spectrophotometer was used. After calculating CIE and skin damage factors and visible transmittance for each piece of glass, an area weighting was used to calculate these factors for the entire Orosi. The results show a significant difference between CIE damage factors of the Orosis in carpeted and non–carpeted spaces where the carpeted spaces had the least amount of CIE damage factor.
