قياس كفاءة تطبيق استراتيجيات التصميم السلبي على نموذج سكني في مصر

Abstract AR

The residential buildings sector in Egypt is one of the largest sectors that consume electricity, which shows the extent of the need to balance the energy consumed and achieve thermal comfort for users.

The research problem lies in the fact that the design of residential buildings does not take sufficiently into account energy saving considerations due to the complexity of environmental control calculations and the study of climate treatments in the design stage, which made residential buildings not achieve thermal comfort for the users and thus leads to dependence on various mechanical means that are economically costly and consuming non-renewable energy And polluting the environment greatly.

So, the study aims to evaluate the negative strategies and treatments used to improve energy consumption efficiency in residential buildings to reach the maximum possible savings in energy consumption without affecting the thermal comfort of users, and to apply these strategies to a housing project in Cairo, and to study their impact on the chosen residential model with the help of By one of the simulation programs used to evaluate the thermal performance of buildings, Design Builder Program.

The final results of the study achieved a total saving of energy consumption estimated at about 29.3% of the total energy consumed annually.
