Enhanced Thermal Performance of Mosques in Qatar
Al Touma, A.; Ouahrani, D. ( Institute of Physics Publishing , 2017 , Conference Paper)Qatar has an abundance of mosques that significantly contribute to the increasing energy consumption in the country. Little attention has been given to providing mitigation methods that limit the energy demands of mosques ... -
Evaporatively-cooled facade integrated with photovoltaic thermal panel applied in hot and humid climates
Al Touma A.; Ouahrani D. ( Elsevier Ltd , 2019 , Article)This study investigates the performance of a hybrid passive cooling system, applied on fully-glazed facades of typical office spaces, in reducing the facade surface temperature and the space thermal loads. The proposed ... -
Improved human thermal comfort with indoor PCM-Enhanced tiles in living spaces in the arabian gulf
Touma A.A.; Ouahrani D. ( EDP Sciences , 2018 , Conference Paper)Al-Majlis is the living space in residential buildings of the Arabian Gulf, and is where occupants spend most of their time. For this reason, the human thermal comfort in this space is of extreme importance and is often ... -
Quantifying savings in spaces energy demands and CO2 emissions by shading and lighting controls in the Arabian Gulf
Touma A.A.; Ouahrani D. ( Elsevier Ltd , 2018 , Article)Despite the deceleration in worldwide annual energy consumption and CO2 emissions, many countries, such as in the Arabian Gulf, are still unarguably far from following this international trend. This study investigates the ... -
Selection of slat separation-to-width ratio of brise-soleil shading considering energy savings, CO2 emissions and visual comfort – a case study in Qatar
Ouahrani D.; Al Touma A. ( Elsevier Ltd , 2018 , Article)The addition of fixed external shading devices to glazed surfaces reduces the space loads and sensations of visual discomfort caused by excessive day-lighting. The slat-to-slat separation distance of the brise-soleil blinds ... -
