Appropriate use of daylightmay decrease the need for electric lighting which may lead to reduced energy consumption and costs inlighting. Moreover, in the Iranian traditional architecture, there have been various passive strategies totake advantage of the renewable resources to provide thermal and visual comfort for users. Using daylightis one of these methods and strategies. The present study aims at analyzing the lighting condition of thesebuildings. Therefore, four buildings in Qazvin city, which belong to Qajar period (1785-7925 A.D.), wereselected as the case studies. Then, the elected buildings were simulated as three-dimensional models.Finally, the analysis of daylight factor and illuminance was conducted using Ecotect Analysis, EnergyPlus and VELUX Daylight Visualizer Software. After the analysis of data obtained from the respectivesimulations and their comparison with the extant standards of lighting, it was found that the averagedaylight factor at all under-scrutiny rooms was acceptable; in addition, 76 percent of rooms requiredno artificial light during the daytime. The reason for appropriate lighting in these spaces is positioningalongside the sunlit side of the building as well as use of big windows. In addition, the analysis ofilluminance shows that the distribution of light in interior spaces is even. Moreover, although muchamount of light enters the space, the use of light color prevents contrast and daze while enhances visualcomfort.}, keywords = {Iranian Traditional Architecture,Daylight Simulation Software,Illuminance,Daylight Factor}, title_fa = {The Analysis of Daylight Factor and Illumination in Iranian Traditional Architecture, Case Studies: Qajar Era Houses, Qazvin, Iran}, abstract_fa = {}, keywords_fa = {}, url = {https://www.armanshahrjournal.com/article_49201.html}, eprint = {https://www.armanshahrjournal.com/article_49201_e03ba0534bdbfaeaca9c5b22fe8278ac.pdf} }
