Abstract: Residential and commercial buildings are responsible for almost half of the total electricity consumption in Egypt. This work deals with the envelope optimization for residential buildings in Egypt with the aim of reducing the cooling needs and projecting those needs in the future. Best available technologies in the market were identified and a series of dynamic simulations were executed in Cairo using those technologies. Financial, energetic, and environmental factors were used to execute comparative analysis to assess the best alternatives. Moreover, measures to further reduce the cooling needs were explored such as the usage of more efficient lighting and night ventilation. The simulations show a reduction of 30% in the cooling energy needs. Future weather files adapted to climate change were generated and used to assess the expected future cooling needs, cooling energy needs, and peak cooling loads are expected to increase by 40% and 22% respectively by 2080.
