Sustainable Mosques have unique functional requirements and operational characteristics. However, the challenge of energy demand reduction in Sustainable Mosques is due to the nature of their daily use for five intermittent periods during the day, and the hot climate of the region. Furthermore, energy demand reduction could be achieved through the design stage by applying measured sustainable design aspects, which considers the unique function of the Sustainable Mosque and sustains the user's needs and comfort. However, this is achieved by assessing the Sustainable Mosque's design through a sustainability assessment system, which considers the special requirements of Sustainable Mosques (i.e. GSAS-Mosques scheme).
Accordingly, this MS thesis 'Examining the Sustainable Mosque Design in Qatar through the Global Sustainability Assessment System (GAS)' is submitted to the College of Islamic Studies (CIS), by Reem A. Al-Mohammed (B.Sc. Architectural Engineering, and GSAS-Certified Green Professional). Under the supervision of Dr. Remah Gharib, and Dr. Esam Elsarrag. The research aims to examine how GAS can control sustainable measures of designing sustainable Mosques in Qatar and can reduce 50% of the energy consumed. This is achieved through proper data collection, literature review, and analysis. In addition to carrying out case studies comparison and comprehensive analysis, of GAS Design Certified Mosques and conventional (non-certified) Mosques in Qatar. In order to set recommendations to retrofit the existing conventional Mosques in hot climate countries to reduce 50% of energy consumption, and to pass the GSAS- Mosques Energy score.
