Nanotechnology has dominated various aspects of life in this age, especially architecture , It is the most promising technology in the field of architecture, It offers a variety of trends in the manufacture of new materials and modified materials after improving their properties, whether in construction materials or non-structural or coating materials, insulation and lighting, It also provides architecture with new systems that narrow the gap between the evolution of modern design methodologies resulting in complex forms and the methods available in the implementation of these forms and complex configurations, Which means that the design process is affected by nanotechnology, It also gave architecture multiple possibilities to form an architectural product that is interacting with the environment through the use of improved building materials such as glass, concrete, etc. -        Therefore, the study of the integration of nanotechnology and architecture increases the level of building performance, Development in this area can lead to the removal of the boundary between the building and the external environment, The casing of the building serves as a data-gathering interface that responds to the stimulus and external influences and adapts them through interaction with different levels of intelligence and responsiveness, The building envelope can also be transformed from one shape to another, from a fixed system to a dynamic one. -         The research deals with the development of nanotechnology and its impact on architecture, and its advanced properties of construction systems and various construction materials, whether concrete, steel, wood derivatives, or various cladding materials, Using digital processing, a new approach to the design and manufacture of building casings can be introduced by controlling the mechanical and physical properties of building materials at the scale of their nanoscale structures and their atomic composition To obtain new materials that are more efficient and effective than the less effective original materials. These new technologies allow buildings to create a dynamic relationship between the building and surrounding environmental factors such as heat, humidity, light, sound and wind, by modifying the performance and behavior of materials and even their form to ensure environmental control and energy saving strategies.
