Improvement of thermal comfort inside a mosque building
Fawaz Ghaleb Noman1, Nazri Kamsah2, Haslinda Mohamed Kama3.
A combined natural ventilation and mechanical fans are commonly used to cool
the interior space inside the mosques in Malaysia. This article presents a study on
thermal comfort in the Al-Jawahir Mosque, located in Johor Bahru, Malaysia. The
objective is to assess the thermal comfort inside the mosque under the present
ventilation system by determining the Predicted Mean Vote (PMV) and the
Predicted Percentage of Dissatisfied (PPD). These values were then compared to
the limits stated in the ASHRAE Standard-55. It was found that the PMV varies from
1.68 to 2.26 while the PPD varies from 61% to 87%. These show that the condition
inside the mosque is quite warm. Computational fluid dynamics (CFD) method was
used to carry out flow simulations, to identify a suitable strategy to improve the
thermal comfort inside the mosque. Results of CFD simulations show that installing
four exhaust fans above the windows on the west-side wall of the mosque is the
most effective strategy to improve the thermal comfort inside the mosque. Both
the PMV and PPD values can potentially be reduced by more than 60%.
