An analytical vision to achieve the Principles of Environmental sustainability in Islamic Architecture Depending on one of the simulation programs ENVI-MET

Sustainable Architecture is one of the most important architectural trends aimed to achieve it as a result of the ongoing environmental problems resulting from buildings such as, Energy consumption in buildings operations. in addition to pollution, as a result of carbon emissions, and this is a modern concept that was announced years ago through global trends interested in protecting the environment with the importance of achieving sustainable buildings. Islamic Architecture is environmental buildings commensurate with the climatic requirements and achieved thermal and social comfort for its users, but it has not been assessed that it has precedence in achieving sustainable environmental buildings, or its inclusion among the successful environmental trends in achieving environmental compatibility. Islamic architecture is dealt with as a distinct architectural concept only.

The research paper aims to address Islamic architecture from a different perspective by presenting an analytical vision whose purpose is to present a new concept for Islamic architecture, which is "sustainable Islamic architecture", according to the perception of the environmental perspective as one of the important environmental tributaries of sustainability, by proving that the concept of sustainability is not new, but rather old and has been achieved Islamic architecture and has an already existing applied legacy، The concept of Islamic architecture was dealt with as a general concept without a spatial or temporal limitation to confirm inclusiveness. Sustainable architecture was also dealt with without a temporal or spatial limitation.

That is why the research paper dealt with the analytical inductive approach by studying the concepts and principles of sustainable architecture and Islamic architecture and how to achieve comfort for its users. Followed by an analytical study of two models of buildings that fulfill the principles of Islamic architecture, namely Al-Suhaimi House in Cairo as a model for an old building, and the American University in New Cairo, in order to clarify the development of the environmental architectural vocabulary, which confirms the sustainability of the concept and the continuity of its application. In order to rely on one of the simulation programs Envi-met as another tool to confirm the hypothesis to evaluate one of the architectural elements, which is the courtyard in a model of an old building (House Al-Suhaimi), for this the study was chosen on the old building and not the modern one, and as a result of these evaluations the research ends Presenting the definition proposed by the researcher for Islamic architecture.
