For example, the albedo of concrete and colored stones decreases over time, while asphalt becomes brighter and increases its albedo. In today's world, sustainable architecture, especially in conjunction with green architecture, plays a crucial role in the use of new polymer materials produced with smart technology and nanotechnology, with an emphasis on using renewable resources instead of the earth's non-renewable resources. Sustainable architecture incorporating green and recyclable materials offers a logical response to the challenges and problems of the industrial age. Building materials play an important role in sustainability. As a metropolis with energy consumption from fossil fuels, high energy costs, and air pollution, the city of Tehran needs appropriate solutions to reduce energy consumption. The purpose of this research is to investigate the amount of energy consumption reduction in residential buildings in Tehran by using three types of ASHRAE standard concrete, engineering system standard, and smart concrete in the external walls of residential buildings, and the result shows that the amount of energy consumption is close in using ASHRAE standard and It shows the engineering system in cladding walls and a significant reduction in energy consumption if smart concrete is used in external cladding walls. https://www.ijumes.com/article_708920_e6bcd27397f8e1e57dbd05d3d948fd56.pdf
