Master Thesis Thermal Comfort Analysis of Historical Mosques, Case Study: the Ulu Mosque, Manisa, Turkey(Izmir Institute of Technology, 2019) Diler, Yusuf; Gökçen Akkurt, Gülden; Turhan, CihanMosques are sanctuary places for Muslims where they can communicate with each other and perform their religious activities. Mosques differ from other building types in terms of occupancy period during a day with their unique function and intermittent operating schedule. Historical mosques with cultural heritage value, contain lots of artworks and represent Turkish culture for centuries. These mosques are originally built and serve without heating, cooling and mechanical ventilation systems. In this thesis, a systematic approach on monitoring and evaluating the microclimate and thermal comfort of historical mosques has been developed. This approach consists of two phases: detailed data collection and developing a dynamic building energy model. As a case study, The Ulu Mosque was monitored between 2015 and 2018. Thermal comfort evaluation of the mosque during worship periods were conducted based on the method provided by EN ISO 7730 standard. A dynamic Building Energy Performance Software, is used to model the mosque, and the model was calibrated by hourly indoor temperature data. The calibrated model, which meets ASHRAE 14 requirements, is used to develop retrofitting proposals. Thirteen different scenarios were proposed to improve thermal comfort during worship periods. The results were then evaluated according to EN 16883 standard in terms of the conservation of cultural heritage. Electric radiator heating with intermittent operating schedules was obtained as the best options to protect cultural heritage, while decreasing dissatisfaction level from 45% to 10% in winter months. Additionally, comparing with continuous operating schedule, intermittent operation saves 46.9% energy.Master Thesis Adaptive Thermal Comfort Analysis of Historic Mosque: the Case Study of Salepçioğlu Mosque, Izmir, Turkey(Izmir Institute of Technology, 2016) Bughrara, Khaled S. M.; Durmuş Arsan, Zeynep; Gökçen Akkurt, GüldenMosques differ from other types of buildings by having intermittent operation schedule. Due to five prayer times per day throughout the year, mosques are fully or partially, yet periodically, occupied. Historic mosques, possessing cultural heritage value, need to be evaluated in terms of thermal comfort. The adaptive thermal comfort method presented by ASHRAE 55 is recommended to be used to analyze thermal comfort conditions of unconditioned buildings. The aim of research is to analyze thermal comfort conditions of historic mosques throughout the year, and to conduct an adaptive comfort analysis. The selected Salepçioğlu Mosque was built in 1905 in Kemeraltı, İzmir, Turkey. The objective is to improve indoor thermal comfort levels by applicable interventions with specific attention to its heritage value. First, indoor and outdoor microclimate of Salepçioğlu Mosque was monitored from October 2014 to September 2015. The physical model of mosque was created via dynamic simulation modelling tool, DesignBuilder v4.2. The model was calibrated by comparing simulated and measured indoor air temperature within hourly error ranges defined by ASHRAE Guideline 14. Whole-year thermal comfort analysis was conducted on monthly basis by using adaptive thermal comfort model. The adaptive comfort analysis of monitoring campaign shows that the Mosque does not satisfy acceptable comfort levels. Different scenarios were applied to better comfort levels. The best improvement is obtained with underfloor heating by which discomfort hours drop into 1369 hours by 31.34%, while it was 3760 hours by 86.08% in the baseline model.
