Energy consumption in residential buildings sector in Egypt is very high, in addition it is estimated to increase more due to the developments in living standards and the growth in population. The study aims to reduce energy consumption of residential buildings in hot climate conditions using Bioclimatic Design Strategies. Those design strategies include three guidelines: energy, human health and sustainability. Moreover, the study merges the Bioclimatic startegies with vernacular strategies to reduce energey comsuption and enhance occupant's thermal comfort. The study adopts a descriptive, analytical and comparitive methodology, complimented with a carried out software stimulation using ANSYS within a qualitative and qualtitative approach. This study concludes with a new design approach for bioclimatic housing units for youth Siwans that will limit energy usage, In addition that it will result as an improved architecture to the climatic environment.
