Most of the previous studies on sustainability dealt with the economic benefits of sustainability in terms of the low operating cost of sustainable buildings in the long term during the life cycle of the building, and did not address the problem of the significant rise in the initial cost of these buildings, which caused the impossibility and scarcity of implementing these buildings in Egypt and the local environment and the continuing trend towards Traditional buildings harmful to the environment and human health. In this research, various strategies that can be used during the sustainable building design process were discussed to reach sustainable low-cost buildings that are easy to spread in the local environment with the use of natural resources and climatic conditions of the local environment.
