Factors such as the rapid depletion of natural resources and environmental pollution enable us to better understand the importance of the concept of sustainability today. With the introduction of the concept of sustainability into the construction sector, the design of buildings according to the environmentally friendly "Green Building" approach has come to the forefront, and various certification systems have been developed. Due to these certification systems, various building materials are required to be used in buildings. However, since there are many materials on the market, it is a problem as to which of these materials should we prefer according to the green building criteria. Although there are various approaches in this regard, the value engineering method is an ideal method because it takes into account both the criteria that the materials must meet as well as their costs. Value Engineering is the teamwork carried out to analyze the building properties, systems, equipment, and material selections, while considering the costs, in order to perform the necessary performance, quality, reliability, and basic functions. In this article, a method on how to choose a value-based, sustainable material was proposed, and as a case study, a product that can be used as an exterior cladding material of a building using LEED criteria, which is used for providing certification for sustainable green buildings, was selected. Initially, a value engineering team was formed. This team determined the qualities that the product should have based on LEED criteria and the eight different material alternatives that can meet these qualities. Subsequently, value analysis was conducted, and the highest value exterior coating material was determined.
