Science is developing significantly in all fields, and of course this development serves the person, and the designer is always looking for everything new and modern that makes his design more successful. The more the designer introduces modern techniques to the design of the internal space, the more contemporary the space becomes, and saves a lot of time and effort, whether for him or for the occupant of the vacuum. Modern technology has provided many and many design solutions and produced spaces that are functionally and aesthetically successful. The world is now heading to the use of modern technologies and advanced technology that achieve savings, whether by energy or raw materials, which also serve the human need and fit with the internal void and its modern requirements and functions, keeping pace with progress and modernity, linking the present with the future, and integrating the originality of thought and environmental character with technology and development. The internal space becomes a smart space in which multiple systems of energy use, temperature control, lighting, sound and communications are compatible, as electronic systems are introduced that work to control different systems of lighting, air conditioning, energy, etc., hence the importance of the research as the research presents applications for the use of technology And modern technologies in interior architecture, and their impact on the concept and vocabulary of interior design.
