Analysis of Lighting Performance between Single Dome and Pyramid Roof Mosque in Mostar, Bosnia Herzegovina

This study analyses a level of lighting performance between pedentive dome and pyramid roof mosque's construction in Mostars, Bosnia Herzegovina. The selected case studies are Karadjoz Beg (pedentive dome) and Neziraga Mosque (pyramid roof) which are located less than 500 metres apart from each other. The purpose is to assess information on the architectural roof design in relation to lighting performance. This assessment is simulated during winter equinox where it provides results when the sun is perimetering at its maximum position at the Tropic of Capricorn. This study applies simulation analysis for of the case study using Autodesk software known as 3DStudio Max programme. This programme creates simulation of the illuminance level to the indoor building areas during winter season when the sun is perimetering at its most southern point along Tropics of Capricorn. A weather file is inserted in the programme during simulation process as a tool to gain accurate condition of the local weather. The analysis shows that mosque with pedentive dome design provides evenly distributed illuminance level with Scale 2 and 3 lighting performance inside the mosque compared to pyramid roof design only with Scale 2. The study concludes that having better illuminance level distributed at all the locations is one of the crucial reasons why the mosques with pedentive dome roof cover are popularly built in Bosnia as well its neighbouring regions by the Ottoman master builders.
