The world has witnessed many crises, including the energy crisis, since the 1970s.This critical crisis draws attention and requires a rapid solution. It found that the main axis of the emergence of this crisis is the residential buildings because it consumes 42.45% of energy source due to the urban expansion energy consumer. Hence, we start towards energy-efficient buildings designed to reduce energy consumption and provide thermal comfort within the building.This trend led to emerging of several solutions using conventional and modern technology applications (including nanotechnology).Therefore, this thesis aims to highlight both the conventional and nanotechnology applications and study the extent of their impact on the building's energy efficiency.The research indicates the use of nanotechnology applications contributes to enhanced thermal performance and rationalize energy consumption more effective than conventional application (currently used). It will also provide solutions to architectural problems in building and construction
