Mosques serve as pivotal hubs for Muslim worship, accommodating intermittent prayer sessions occurring five times daily. Comprehending the environmental dynamics within air-conditioned structures experiencing varying occupancy is imperative informed design decisions. This study aims to analyse a Malaysian mosque's thermal conditions, including comfort temperatures and compliance with standards. It also seeks assess indoor air quality by measuring CO2 concentrations estimating ventilation...
Rising temperatures due to climate change will impact both the indoor thermal comfort of naturally-ventilated housing and cooling energy needs air-conditioned in tropical regions. This study aims evaluate rising based on IPCC A2 scenario a typical Malaysian terrace house. It addresses three key questions: 1) Can passive (PC) achieve future thermally acceptable conditions? 2) How PC with air conditioning (AC)? 3) What is effectiveness various methods, individually combined, controlling saving...
An effective passive cooling strategy is essential for reducing energy consumption in a residential building without ignoring thermal comfort. Therefore, field measurement on the performance of corner terrace house Kuala Lumpur was conducted to reveal effectiveness free running (FR) with four different approaches – no ventilation, full day and night ventilation. The done all bedrooms family area first floor. Also, mixed mode (MM) consisting natural mechanical ventilation ceiling fan, an...
Understanding the environmental dynamics of air-conditioned mosques hosting five daily prayers with fluctuating occupancy is essential for informed design decisions.This study investigates a Malaysian mosque's thermal environment and worshippers' perceptions, including comfort temperatures.Field measurements spanned week included various prayer times.A questionnaire-based adaptive was conducted after Friday midday when worshippers fully occupied main hall.The mean indoor air temperature...
Mosques are used five times a day according to the prayer schedule, which follows sun's position. Indoor thermal conditions in air-conditioned mosques maintained with cooling time pattern that times. Therefore, an effective air conditioning operating strategy is needed for energy efficiency. This study aims investigate effect of intermittent operation strategies on usage mosque. It involves reducing period before and swapping active periods from pre-prayer calls post-prayer base case. Field...
The purpose of this study is to investigate the potential mitigation strategies overcome overheating issue at attic landed residential house located in a hot and humid climate area. An existing terrace with 178 m 2 was selected for research. A building simulation model created calibrated by using previous site measurement data collected Ng et.al. year 2018. subsequently used evaluate various retrofitting methods strategies, including roof insulation, passive radiative cooling methods. shows...
Abstract Accuracy and verification of instruments for thermal environment measurement are important to determine the reliability measured parameters. The purpose this study is propose simple procedures consistency check on four groups used in measurement: indoor air temperature, outdoor relative humidity, velocity. For temperature measurement, existing were checked with new thermocouple connected a data logger an air-conditioned room. was conducted under different set point temperatures....
