    Choosing sustainable building materials is an important strategy in designing sustainable buildings, especially in Iraq due to the nature of the environment and atmosphere. This study helps in the selection of building materials by providing appropriate solutions to two main issues: (identifying the most important criteria for selecting sustainable building materials and the process of prioritizing and determining weights for these criteria).. Evaluation criteria are determined based on sustainable criteria for selecting building materials and the need for sustainable construction that serves everyone, especially engineers and stakeholders The criteria were determined through previous studies and through theoretical examination. Indicators were collected from the former research, studies and literature review as well as from theoretical topics relevant to the issue of selecting sustainable building materials used in construction projects, where a survey of construction experts was conducted, where the criteria were divided into four main criteria and (31) sub-criteria, and the SPSS method was used to analyze the data obtained through the experts' questionnaire. In this field, the Fuzzy Hierarchical Analytical Process (Fuzzy AHP) method was used to analyze the data. To calculate the relate criteria weights to use the significance of these criteria for selecting a particular material alternative. On the ground, this model can provide guidance to building designers in selecting sustainable building materials to contribute to the sustainable building process For the purpose of applying this framework (a framework for the sustainable selection of building materials used in construction projects in Iraq), a case study was conducted for the purpose of making multi-criteria decisions using the fuzzy AHP method to solve the problem of selecting sustainable materials. Where the case study includes the selection of three types of bricks used in construction in Iraq, which are red bricks (red), yellow bricks (yellow), and solid yellow bricks (yellow s). And to apply. The framework that was proposed in this study for the purpose of selecting the most sustainable types of bricks .The same criteria and sub-criteria used in this research were used and applied to alternative subjects It emerged from the general evaluation of the three materials using the Fuzzy AHP technique, which aims to find the best materials, and it was found that the importance of red bricks is the highest rank (1), the second importance of yellow perforated bricks (yellow) rank (2) and the third importance of solid yellow bricks ( yellow s) rank (3). These results correspond to reality, according to the opinion of experts .It can also help stakeholders, project managers and contractors to choose sustainable building materials and eliminate weaknesses by taking action at an early stage in order to obtain a building with a high level of sustainability.
