A study of unutilized energy in UiTM buildings / Muhammad Helmi Hamidon

The problem of energy wastage in several buildings in MARA University of Technology (UiTM) has reached a level that is very concerning. After reviewing audit reports on all UiTM buildings, the scenario of energy wastage has been identified happening in several buildings. UiTM's Maintenance and Development office has been identified as some of the buildings that are experiencing unutilized energy, or in other words, wastage of energy. A detailed observation on load profiles for both UiTM's Maintenance and Development offices show that there exists energy wastage during the overnight period. Field investigations conducted identified the sources of these unutilized loads and air conditioning units, mainly split units has been identified as the main components consuming energy during the overnight period. Wastage in energy has been sourced to air conditioning units that are not turned off after working hours. Hence, it can be concluded that there are opportunities for improvements in terms of energy consumption in UiTM buildings and implementing a suitable control system to reduce energy wastage in both the Maintenance and Development offices will ensure that operation cost is minimized and energy usage is optimized.
