Abstract
The Lightweight Steel Frame technology (LSF) employs pro les made by thin steel and manufactured by cold forming. This technology dates back to the mid-1800s and today the exibility of the industrialized production enables innovations and bene ts in the use of it: buildings can be designed with a very high level of detail, using the precision of the industrial design or on-demand production. Each pro le in Cold Formed Steel (CFS) is designed and built for a speci c purpose and industrial nishing follows the work of the designer, without imposing constraints, such as modularity and mass production. The manufacturing of cold-formed steel rods is made by pro ling, or press bending. The use of CAD/CAM solutions for the design and the production promote the di usion of pro ling during LSF processing. The CFS rods can be produced of whatever length (even all of di erent lengths) from the same sheet metal strip and without interrupting or slowing down the processing. Furthermore, shapes and pro les can be many and di erent. The manufacturing is highly customizable, just so the changes in shapes and pro les are carried out in compliance with the UNI EN 1090 and meet the tolerances required by law. Design a building with the LSF system requires attention to seve- ral issues. The CFS is a real system and a ects the calculation of the structures so, a correct approach to the project is crucial. The collaboration between designer, structural engineer, engineering, manufacturer, and con- struction company can’t be underestimated. The quality of the project and of teamwork allow to realize low cost buildings in a short time and with high performance. These design principles also allow the development for an accurate sustainability analysis. Thanks to the Life Cycle Analysis (LCA), all kinds of processing can be described in terms of energy and CO2 emission costs. This analysis can be performed right from the ma- terials production and construction elements. The research focuses on the project and the buildings even during the phase of use, consider main- tenance and theorize the disas-sembly operations (or demolition) and recycling (or reuse) of the constituent parts of the buildings.
