They are used in facade panels, structural beams, and even entire modular units, offering superior strength, corrosion resistance, and reduced weight. For example, the use of composites in bridge construction allows support systems to be significantly lighter while maintaining safety margins.

b. Modular and prefabricated building techniques

Prefabrication involves manufacturing standardized modules off-site, which are then assembled on-site. This approach accelerates construction, reduces waste, and allows for the use of lightweight materials like insulated panels and metal frameworks. Modern projects, including eco-friendly urban habitats, leverage these methods for greater flexibility and sustainability.

c. How simulations and modeling improve the efficiency of using light materials

Advanced software enables engineers to simulate structural behavior under various conditions, optimizing material distribution and minimizing waste. Finite element analysis (FEA) helps predict stress points and improve design efficiency, ensuring safety and durability of lightweight structures, as seen in the planning of innovative habitats like My Sweet Town.
