In this study, the analysis is to measure lighting performance of single pendentive dome type and pyramid roof type in mosque design built during the Ottoman Empire in Istanbul, Turkey and Mostar, Bosnia-Herzegovina. The selected case studies are the Firuzaga and Orhan Gazi Mosques as single pendentive dome styl and Neziraga Mosque as case study for the pyramid roof type. This analysis aims to have a research finding to show that Turkish style’s pedentive dome mosque design provides efficient indoor daylighting in the Orhan Gazi Mosque in comparison with the Firuzaga Mosque and Neziraga. This assessment is simulated during winter solstice occurred when the sun is perimetering at its most southern position along the Tropic of Capricorn. This study applies simulation analysis using Autodesk software known as 3D Studio Max Design 2011 programme. The simulations were done by the program using weather data file to provide the weather information and climate changes of the study area. The analysis shows that both mosques have mostly an evenly distributed illuminance level with Scales 1 to 5. The Orhan Gazi Mosque has slightly higher illuminance levels compared to those of the Firuzaga Mosque and bothe of the pendentive dome mosques have butter illuminance level than the pyramid roof mosque. The study concludes that the pedentive dome mosque design has an effect on the mosque indoor daylighting. Having excellent illuminance level distributed at all the locations is one of the crucial reasons why the mosques with pedentive dome roof cover are built by Ottoman master builders.
