This study aimed at identifying passive and active design features through extensive literature study that can be incorporated in buildings to make them energy efficient. The study also aimed at identifying changes in the design process that can affect energy efficiency in buildings. The study has analyzed the design features of typical buildings in Gaza Strip through a case study conducted on Irada building at Islamic University of Gaza. It also analyzed the present electric energy used for lighting, HVAC and induction motor loads.It offers possible energy saving by adopting certain energy efficient features in Irada building at Islamic University of Gaza. It also analysis proposal for building envelop insulation in Irada building that improve energy efficiency, based on the calculation of energy savings associated with the use of HVAC system (to assure a certain comfort temperature). The findings from this study indicate that by adopting certain energy efficient features in Irada building, we can reduce the annual energy consumption by 24% for low cost model and by 41% for high cost model. It also finding from feasibility study through using three methods which are; simple payback method (S.P.B.P), net present value (NPV) and interest rate of return (IRR) that this type of projects is feasible to encourage the investors to invest In it. Finally it can be concluded that the process of designing energy efficient buildings is the best method to improve the efficiency of electricity sector in Gaza Strip which suffers from many problems such as high electrical deficit rate, high transmission losses, high electricity prices per kWh, annual growth and absence of energy management strategies and skills.
