Energy Efficiency Analysis And Auditing Of Ethiopian University Buildings Case Of Buildings In Arba Minch Institute Of Technology

In this paper the results of the energy audit of buildings in Arba Minch Institute of Technology AMIT are presented. The objective of the study was to identify the energy lossy applications activities and traditions and to suggest the least costly energy conservation mechanisms. All functional lighting systems office equipment desktop computers and water fixtures showerheads dishwashers toilet flushers and hand washers are taken into consideration for the study. Increased energy consumption due to daytime operation of lighting systems inactive mode operation office equipment and desktop computers and poor water management practices were the focus of the study. Based on the audit results poor water management practice in the campus contributes the most to the total energy loss followed by the inactive mode energy consumption of desktop computers and daytime operation of outdoor lighting systems. Therefore a significant amount of energy can be saved by practicing regular maintenance of water fixtures and pipes in the campus. Moreover awareness creation campaign can help a lot in reducing the energy loss which could be resulted from inactive mode energy consumption of computers and daytime operation of lamps. Installation of electronic day light control and motion detection systems can be potentially used to reduce the energy consumption of lighting systems operating in the daytime and in class rooms and halls both in the day and night time respectively.
