This study aimed at identifying design features that can be incorporated in buildings to make them energy efficient. Energy audit and analysis is necessary to increase building energy efficiency. Three methods to increase energy efficiency were selected based on installation cost: the first method of low cost is replacing T-8 fluorescent lamps (FL) and Metal Halide lamps (ML) with T-5 and High Pressure Sodium (HPS) respectively, the second method of medium cost is replacing all FL and ML lamp with Light Emitting Diode (LED), and the third method of high cost is the automation system for room lighting based on fuzzy logic controller at some places in the building. Energy audit and analysis was performed on Irada building at Islamic University of Gaza (IUG). Good energy saving were achieved using low cost, medium cost, and high cost methods. Finally, this provided much needed power saving to be reused in Gaza Strip.
