Energy Consumption and Potential Saving in MSI Complex
Keywords:MSI, achieve cost saving, ACMV system, energy consumption
MSI is a mosque located in Universiti Tun Hussein Onn Malaysia and known as Masjid Sultan Ibrahim. The mosques are considered unique compared to other types of buildings as they exhibit an intermittent operation schedule. This study aims to discover potential saving and provide solutions to achieve cost saving of Masjid Sultan Ibrahim of UTHM. Four potential saving methods were proposed later in this study, which include the installation of sensors, replacement of LED lamp, placement of reminder sign, and human control respectively. Result was found that about 64% of electrical energy was used on ACMV system, 35% on lighting system and the rest were general equipment. From calculation, the monthly electrical energy consumption of Masjid Sultan Ibrahim was near to 36MWh. With the proposed potential saving measures, Masjid Sultan Ibrahim is estimated to reduce the usage of electrical energy for about 13% per month. More potential saving could be found in future study if there is designated system that studies the energy consumption trend of the building.
