The expansion of urbanization has changed the type of land cover and impervious materials in architecture such as asphalt and construction materials have replaced natural soil, and these impervious materials and surfaces are important factors affecting thermal comfort and the environment. The use of urban materials with a high albedo, in addition to reducing the effects of heat islands, can have positive and negative environmental effects. Smart materials are a new term for materials and products that can understand and process environmental events and react accordingly. The current research is descriptive-analytical type, which is considered as an applied purpose, and considering the extraction of the optimization model. The research tool is the library and the analysis stage in the form of case sampling and also the use of simulation and analysis software like Open Studio. 9.5 in the sample materials is recognized. As a result, the main issue in cold climates is providing thermal comfort in the indoor space in winter, and for this purpose, various equipment and insulation works are used in buildings. The results show that in the general state of gas energy consumption, which is the dominant energy for providing internal heating of the building, if Smart concrete of thermochromic type is used in the outer walls of the building, approximately 19-22% of the energy consumption required for It has reduced the generation of heating. Therefore, this amount of energy saving in a building can create significant efficiency in the urban context and on larger scales.
