Material Efficiency

Definition

Material efficiency refers to the optimal use of materials in construction and design to reduce waste and improve sustainability while maintaining structural integrity. This concept emphasizes using the least amount of material necessary to achieve the desired performance and safety, which is crucial for both cost-effectiveness and environmental impact. Material efficiency is particularly relevant in design considerations and in the selection and optimization of structural systems.
