Twelve residential colleges located at the capital city of Kuala Lumpur were selected for an energy audit to evaluate the performance of electricity use according to the Energy Efficiency Index (EEI). The residential colleges that had special features of building layout and arrangement, such as courtyards and balconies, performed better with regard to electricity consumption compared to the buildings with a linear arrangement, due to the prior group’s superior utilization of day lighting and natural ventilation. In addition, the floor area of the rooms, the volume, density, enclosural and facade design including window design, area, window to wall ratio etc. also influenced the total electricity usage of the residential college buildings. The fluorescent lighting and fans are two major contributors to total electricity usage, and with an adaptation of the corridor area to include more natural ventilation and day light, the electricity consumption can be markedly reduced. As a result, it was shown that approximately 40 to 80% of average electricity usage could be conserved in a year, while at the same time improving the indoor environmental quality.
