CHANGES IN INDOOR AIR TEMPERATURE DUE TO DIFFERENT OPERABLE PANEL WINDOW AT MOSQUE DURING RAMADHAN (PERUBAHAN SUHU UDARA DALAMAN MASJID TERHADAP OPERASI PANEL TINGKAP YANG BERBEZA KETIKA RAMADHAN)
Abstract
Abstract
Jemaah need to gain a feeling of comfort, peace, and serenity during their religious congregations especially during Teraweh prayer as it takes a longer time indoor (about one h and 30 min). Hence, this study was conducted to evaluate the temperature change (T) (°C) at different operable window (i.e. close and open windows). The monitoring was conducted within the main prayer hall of Masjid Seri Ampangan for four h and 30 min from 18:00 to 22:30 h (before Maghrib until Teraweh prayers). T and relative humidity (RH) were measured using an indoor air quality probe (IQ-610) Graywolf Model whereas air speed hot wire (AS-201) Graywolf Model was used to measure air movement (AM). The results indicated that the T within the main prayer hall could be reduced by lowering the percentage of the dead wall (%) (i.e. Open window). The 7.98 %, difference in average percentage of dead wall between close window (98.49 %) and open window (90.51 %) has reduced the T by 0.46 °C within the main prayer hall of the mosque. Therefore, this study suggested that perhaps by increasing the opening area (reducing dead wall) could reduce the T within the main prayer hall of mosques.

Abstrak
Jemaah perlu mendapat keselesaan, kedamaian, dan ketenangan semasa melakukan aktiviti-aktiviti keagamaan terutamanya semasa solat Teraweh kerana ia mengambil yang lebih lama (kira-kira 1 jam dan 30 minit). Oleh itu, kajian ini dijalankan untuk menilai suhu (T)(°C) apabila panel tingkap mempunyai operasi yang berbeza (panel tingkap yang tertutup dan terbuka). Pemantauan dilakukan di dalam dewan solat utama Masjid Seri Ampangan selama empat jam dan 30 min dari pukul 18:00 hingga 22:30 jam (sebelum Maghrib hingga solat Teraweh). T dan kelembapan relatif (RH) diukur dengan menggunakan indoor air quality probe (IQ-610) Graywolf Model manakala air speed hot wire (AS-201) Graywolf model digunakan untuk mengukur pergerakan udara (AM). Keputusan menunjukkan bahawa T di dalam dewan solat utama dapat dikurangkan dengan menurunkan peratusan dinding mati (%). Dengan perbezaan sebanyak 7.98%, diantara peratusan purata dinding mati untuk tingkap tertutup (98.49%) dan tingkap terbuka (90.51%), T dapat diturunkan sebanyak 0.46 °C di dalam dewan solat utama masjid. Oleh itu, kajian ini mencadangkan dengan meningkatkan kawasan terbuka berkemungkinan dapat mengurangkan T dalam dewan solat utama masjid.
