With the continuation of technological development and what has been demonstrated by the massive expansion in modern technologies, we now need to ensure that this expansion does not cause a huge increase in the consumption of energy and resources, and that it does not have a negative impact on the environment and human health, as modern technical developments provide pioneering opportunities. To monitor and protect the environment, in addition to preserving the general health of the planet, by harnessing it in the most appropriate manner, modern technologies can be directed to enhance ecological design in order to preserve the environment and humans. Through this, the research problem is revealed by the following question: What is the role of smart technologies? What is its impact in the designs of sustainable interior spaces? While the importance of the research study contributes to highlighting the importance of preserving the environment through the use of smart technologies and the selection of environmentally friendly building materials. While the current research aims to reveal the role of smart technologies and the clear reflection they achieve in the designs of sustainable interior spaces, the research study also included the axes of the theoretical framework as well as the research procedures represented by the research methodology based on the descriptive analytical approach (case study). Finally, the research study included extracting the most important Results, conclusions, recommendations and future proposals.
