“…In another study, CFD simulation system was employed to assess the optimum reduction of IAQ of Al-Haram mosque in Makkah. The model output revealed that indoor CO 2 levels were reduced by increasing the ventilation rate (Jaafar et al, 2017). Hence, a study concluded that the residents of KSA would prefer of purchasing houses with improved ventilation systems to reduce indoor air pollution (Opoku and Abdul-Muhmin, 2010).…”

“…Therefore, during the last decade, several studies indirectly [ 5 , 6 , 7 , 8 , 9 ] or directly [ 1 , 10 , 11 , 12 ] focused on the problem of pollutant concentration and thermal comfort in closed spaces. All of the research focusing indirectly on excess CO 2 (or other contaminants) approaches the problem by using numerical studies in cavities, namely computational fluid dynamics (CFD) simulations [ 5 , 6 , 7 , 9 , 13 ].…”

Due to the current COVID-19 pandemic, guaranteeing thermal comfort and low CO2 levels in classrooms through efficient ventilation has become vitally important. This study presents three-dimensional simulations based on computational fluid dynamics of airflow inside an air-conditioned classroom located in Veracruz, Mexico. The analysis included various positions of an air extractor, Reynolds numbers up to 3.5 × 104, four different concentrations of pollutant sources, and three different times of the day. The simulations produced velocity, air temperature, and CO2 concentrations fields, and we calculated average air temperatures, average CO2 concentrations, and overall ventilation effectiveness. Our results revealed an optimal extractor position and Reynolds number conducive to thermal comfort and low CO2 levels due to an adequate ventilation configuration. At high pollutant concentrations, it is necessary to reduce the number of students in the classroom to achieve safe CO2 levels.

“…For mosques, feeling comfortable during the prayer help worshipers to attain a feeling of tranquility, peace and serenity. The authors of [6] studied air change rate influence on indoor air quality in Al-Masa'a between Al-Safa and Al-Marwa hills inside Al-Haram mosque using a CFD simulation software. The authors of [7] monitored and assessed, according to the ASHRAE standard 55 (2010), the quality of indoor thermal comfort of an old mosque in Turkey.…”

Post Energy Audit of Two Mosques as a Case Study of Intermittent Occupancy Buildings: Toward more Sustainable Mosques

et al. 2020

Mosques are buildings with a unique occupancy schedule and special energy and water consumption scheme. Generally, this type of buildings lacks the application of energy efficiency solutions and sustainable guidelines during the conception, construction and the operation phase. Interestingly, these iconic edifices can play a key role in raising awareness for sustainability and promoting cleaner energy technologies. The first aim of this work is to present energy audit results, recommended energy savings solutions for two historical mosques in Marrakech (Morocco). A detailed discussion of the adopted solutions is presented and an economic assessment was performed. Then, a two-year energy savings evaluation was conducted for the two mosques. Conclusions about the adequacy of the proposed solutions is presented. The second part is dedicated to outline some guidelines and sustainable criteria to consider for establishing an international sustainable mosques label. The creation of a such sustainable label will encourage spreading sustainable best practices in mosques and other types of buildings. It will also help to compare sustainable performances of different mosques around the world by establishing an adapted sustainable rating system.
