Mohammadi, Pouria / Ramezanianpour, Amir Mohammad / Erfani, Abdolmajid

Buildings have a significant and continuously increasing impact on the environment because they are responsible for using a considerable number of resources and a large amount of energy besides emitting a large portion of carbon. In recent years, numerous attempts have been made to reduce these harmful impacts of construction activities to achieve sustainable development goals. Careful selection of buildings materials has been identified as the first step for designers to incorporate sustainable principles in building projects. As far as sustainability is concerned, façade plays a prominent role in high-rise buildings. Therefore, criteria for selecting sustainable facade materials of high-rise buildings should be studied in order to have sustainable buildings. In this paper, a comprehensive list of sustainability criteria for selecting façade materials is presented through extensive literature review and expert interviews; afterward, these criteria are prioritized using Fuzzy Analytical Hierarchal Process (FAHP) model using a survey. The study’s results showed that the environmental criteria are of the highest importance from the point of view of experts. Followed by the economic, technical, and social criteria group respectively. The result of this study could help decision-makers in selecting façade materials during design phase.
