Abstract
With the global energy crisis and the emergence of sustainable development issues, architectural design must be mastered, not only to ensure a comfortable indoor environment, but also to control energy consumption and its impact on the environment. Comfortable buildings, energy efficiency, and positive energy buildings are all current issues that require knowledge of the basic principles of sustainable development in buildings. Moreover, understanding the values that characterize materials is essential today to choose products wisely from a technical and economic point of view. This work proposes to articulate them by focusing on Functionally graded material (FGM) as a design tool. Thus, it seeks to contribute to convert the concept of gradient into reality with accuracy and precision thanks to the manufacturing processes based on the new technology.
