The purpose of this research is to evaluate and assess the residential buildings energy consumption in the east cost of the Arabian Gulf region. After, conducting the energy performance assessment, the main goal is to reduce the energy consumption of those homes to reach the net-zero stage. Moreover, a net-zero strategies tree have been created. The tree has so many elements in order to help designing the Net-Zero prototype which going to reach the Net-Zero stage see fig.1: the strategies are :- renewable energy, passive technique and enhancing building quality. Furthermore, at the beginning of the research, a study was made for the Arabian Gulf vernacular architecture in order to help designing the net-zero prototype and learn some construction lessons from them since individuals were living in a net-zero homes at the time (no electricity).
