The purpose of this study is to determine the energy usage and energy efficiency in Al-Azim Mosque Melaka which to determine the electrical appliances that have been used by mosque such as fans, lights and air-conditioner. The mosque only use fans and air-conditioners in office. Its electricity bills is surprisingly high which costs more than RM14, 000 every month where the electricity bills cause burden to the mosque committee. Basically the income of the mosque come from donation of the worshippers. Thus, the saving of electrical bills will be used for others benefits such as increase the number of activities in the mosque. The aim of this study is to determine total power consumption and energy saving measures in Al-Azim Mosque and to identify the current thermal condition and opportunities for improvement of fans power consumption without compromising comfort level. There are two methods used to determine the energy efficiency in this project by measure and verify the actual power consumption in Al-Azim Mosque in order to search for significant energy usage that can be reduced. Thus, the thermal comfort is to focuses on the suggestion of the usage of fans and office air-conditioners in mosque in order 10 determine the potential energy saving plan. The area for the power consumption has been setup at the electricity main board in Al-Azim Mosque. Then, the thermal comfort methods have select the prayer arca which consists of nine points, point A, B, C, D, E, F, G, H and I. The main physical parameters involved in this project are air temperature (Ta), relative humidity (RH) and air velocity (Va). The measurement is taken by using Three-Phase Electrical Networks Analyser for the power consumption and Thermal Micro Climate for the thermal comfort method. The power consumption research by using Data Viewer Software and the thermal comfort analysis of this study is conducted through Delta Log 10 Software. The power consumption focus on fans ‘which has used about 2% and office air-conditioners usage is about 10% from the total power usage. Hence, the balance from the total percentage is used by lighting. Furthermore, the Coefficient of Performance (COP) for air-conditioners in several rooms has been such as air-conditioners in offices, meeting, Imam and Muezzin rooms. Thus, all the sample rooms have met the criteria which have achieved more than 2.7. Based on the COP results obtained, all the air-conditioners in the sample room are in good conditions and the eficiency of them are in satisfactory range. Next, the thermal comfort also included the analysis Predicted Mean Vote (PMV) and Predicted Percentage Dissatisfied (PPD) index of measurements. According 10 the obtained results, almost all the air temperature and relative humidity measurement was satisfied the standard and almost 90% air velocity readings were not satisfied the current standard. Furthermore, the questionnaires has been compare with the PMV and PPD results, the results shows the occupant’s thermal sensation has met the results for PMV and PPD.
