The consumption rate of energy in higher education institutions has been rising steadily in recent years as a result of the expansion of campus facilities, increased working hours, and the increase in the number of students. In these settings, residential structures constitute a large proportion of aggregate electricity consumption, with lighting systems running over extended hours, and with lighting systems having a direct impact on energy consumption and comfort of occupants. Consequently, the enhancement of the performance of lighting systems has become one of the priority areas of the institutional energy efficiency programs. Lighting system performance dictates energy consumption in institutional residences, and as such, it is one of the priority areas in which efficiency can be improved. Satria Residence College is a campus that is now using traditional Fluorescent (FL) lamps at Universiti Teknikal Malaysia Melaka (UTeM), which are adding to the overconsumption of power and increasing maintenance expenses. To overcome these difficulties, it is necessary to replace FL lamps and conduct a regular analysis of other designs prior to implementation. The paper is a simulation analysis of a retrofitting measure, which substitutes FL luminaires with Light Emitting Diode (LED) luminaires. A preliminary model of the existing setup was developed with the DIALux Evo to determine baseline values of the illuminance, uniformity, and energy requirements. It therefore led to re-simulation of the same layout with LED luminaires under the same conditions, and this provided a direct comparison of the two lighting qualities and energy performance. The assessment model focused on the adherence to the Malaysian Standard MS1525, although the visual comfort requirements were also met. The findings reveal that retrofitting to LED luminaires results in quantifiable changes in lighting performance in terms of energy efficiency. These results show the usefulness of simulation-based assessment when looking at retrofit decisions in relation to institutional homes. The research not only provides a methodological source of information on sustainable lighting upgrade within UTeM but also advances the broader objective of energy efficiency in campuses.
