The research problem is that the traditional techniques and materials used in buildings, have a specific impact on energy savings in buildings within certain limits. The research aims to use nanomaterials to provide thermal comfort in the building while rationalizing energy consumption without neglecting the architectural formation and aesthetic appearance.Therefore, an inductive and deductive approach was used to achieve the goal of the research. The research reached a group of nanomaterials whose roles varied between thermal insulation, the amount of energy consumed for lighting, or the extent of the impact of nanomaterials on global warming, and thus their role in the process of energy conservation in the building.
