The principles of environmental design have become the basis of architectural thought, starting from the early stages of the design process and ending with the selection of appropriate building materials in order to achieve sustainable external envelope. Architects began to use new materials in order to reach an environmental design for the building, which led to a qualitative architectural leap that led to the discovery of building materials that contribute to achieving environmental efficiency. This thesis aims to study modern building materials and their environmental impact on the building by achieving thermal comfort by understanding and studying various environmental characteristics. This thesis relies in its methodology on a theoretical study of a group of previous studies in this field, presenting a theoretical study on the environmental performance of the building and the study of modern building materials and their environmental characteristics and their impact on the environmental efficiency of the building, then Building information modeling technology and how to benefit from it in analyzing the environmental performance of the building was studied, then it dealt with an analytical study of global, regional and local experiences to study how to deal with the environmental characteristics of modern building materials. Then an applied study in which the current situation in the case study is monitored, and the current environmental performance of the building is measured using one of the environmental performance analysis programs of the building, then the application of materials with different environmental characteristics and comparing the results.
